Dual Monitor - Secondary Monitor Flashing Issues

Question: Dual Monitor - Secondary Monitor Flashing Issues

I recently purchased another monitor so I can run dual-monitors on my newly upgraded-to Windows 8 desktop. I set the monitor up last night, and I haven't had any major issues so far... One issue that I've run into, though, is the secondary monitor (regardless whether it's the monitor I owned first or the one I just bought) flashes randomly. Last night, a restart fixed the issue, so I didn't think anything of it. Today when I started it up, it was fine again for about 5-10 minutes. Then it began to flash randomly. It's not a constant steady flash, it only happens once every 3-10 minutes, but it shouldn't be happening. Does anyone else have the same problem and/or have suggestions on how to fix it?

Add'l info:

Monitors (both connected via HDMI, primary to primary gfx card, secondary to secondary gfx card)
1x Asus VW246H 24"
1x Asus VE248H 24"

Both set to 1920x1080p resolution, left as primary, right as secondary.

GFX:
2x EVGA Nvidia GTX 560 Ti's in SLI Configuration

Most recent stable Nvidia drivers are installed. I'll test the beta ones later and update this if anything changes.

Hi all,

I have been running a dual monitor setup on a Windows 10 PC and ever since a windows update a few weeks ago I have been having the following issue..

When I boot up the PC initially I see the same display on both screens, all perfectly normal. However when I land on the PC login screen all i see is a black screen with a cursor.

Just before the PC loads up this screen, my 2nd monitor (which should display the password login screen) loses signal, so I know the PC is loading up fine, it's just not displaying on the monitor.

Strangely when I manually switch the PC off via the power button and then switch it back on again everything starts up fine, the 2nd monitor is posting/receiving a signal.

I have checked for updates on my graphics card but I have the most recent ones. The graphics card is quite old (roughly 7 year old Nvidia card.

I have looked at the display settings menu and the monitors appear to be configured correctly.

Does anyone have any ideas as to how this can be solved?

Thanks,

Chris

I have just did a clean install of Windows 7 ultimate from XP and I am unable to get my dual monitors to work like they did in XP.

I have a DVI Radeon graphics card plugged into the agp slot, and a Nvidia geforce vga adapter plugged into a pci slot of my dell optiplex 755. When I am in the screen resolution settings the second monitor cannot be detected.

In bios I have 2 options under primary video adapter and they are auto, and onboard card. When set to auto the Nvidia card gets a signal but the Radeon does not. There are no conflicts in the device manager, and all of the drivers are up to date.

When I change the bios option to onboard card the Radeon adapter gets a signal but the other monitor cannot be detected and in device manager there is a yellow exclamation mark next to Standard VGA adapter and a code 10 error that states the device could not be started.

I have powered down, and unplugged every cable, I also tried to use the integrated VGA adapter to the Intel G31/G33/Q33/Q35 Graphics Controller but the computer will not even boot. I get
"System Halted
Attention Unsupported Video Configuration Detected"

I have two monitors, both work fine as standalones but Windows will not detect either as a secondary.

Please help me someone, I am so used to having my helpdesk email open in one monitor and all of my other work in the other monitor.

Answer:Dual monitor issue, secondary monitor is undetectable

Welcome!

Try updating your card drivers. Go into Device Manager and right-click on your display adapter.

I suspect that the cards are too old, though. We will see.

I have a dual monitor setup, where the laptop is hooked to a 2nd monitor (TV) thru an HDMI . I primarily use the 2nd monitor. Can I blank screen the 1st (laptop screen) monitor, yet continue to use the 2nd monitor with the lid open for access to the keyboard?(I noticed with changed settings in Win7 control panel, I can close the lid without cutting off [sleep, hibernate or shut-off] the computer and had to reduce the 2nd monitor display to fit the visible screen. But to use the keyboard one has to open the laptop lid, which kicks in the 1st screen)Thank you

I am using a 22" screen for my primary screen and the laptop lid open for a secondary screen. The main screens resolution is 1680x1050, I can set it to anything I want and it's always using the full screen. The laptop screen on the other hand will only use the full screen if it's at 1400x1050 resolution (max for that screen, IBM Thinkpad T43). With the large 22" screen I have no trouble reading the screen at high resolutions, the screen is huge, with the little 14" screen though I have to strain to read the screen at 1400x1050.

The problem is when I set the laptop screen to anything lower than 1400x1050, it uses less of the screen. Preferrably I want it at 1280x1024 or 1024x768 (I dont know which I want yet as I can't see the freaking screen at that resolution). At 1280x1024 for instance the useable screen is just a box in the middle, so the "1280x1024" is still barely readable for me cause it's shrunk from full screen, plus it's just annoying only using a portion of the screen.

I have played with the ATI Control Center, the Thinkpad display settings and windows display settings and just cannot get this thing to go full screen at lower resolutions when docked and using the external monitor.

Anyway to resolve this?

I have two monitors hooked up, my primary is a 22 inch samsung my secondary is a 19 inch microtek. My problem is that some things (mainly firefox and Documents) open on my secondary monitor. Even if I move the window to my primary monitor maximize it and then close it, when I open it again it opens on my secondary. I really only use my secondary monitor for design work in photoshop, illustrator etc. so it is off a lot of the time. It is annoying to have to turn it on just to move firefox over to my primary one.

What would cause this problem and it only does it with some programs and windows, but not all
Thanks

Answer:Dual Monitor Secondary Display

try this: minimize the window drag it to the appropriate monitor, and close it while still windowed.
Relaunch the program and it should appear windowed on the correct monitor. After maximizing and closing it again it should launch fullscreen, and in the correct monitor.

Need help with dual monitor setup. First time trying to do it.

2 Problems
1.
Second monitor does turn on, but is only showing native resolution (1024 x 768) but it has the ability to go up to 1280x1024.
I want to to be able to set it to 1280x1024.

2.
Second monitor will not boot up along with computer.
I shut down my PC, the monitor is still plugged in, and it doesn't wake up automatically.
Things I've tried
- Updating drivers, obviously. (Nvidia, etc.)
- Uninstalling default driver of second monitor in Device Manager then rebooting computer, then plugging out and replugging the monitor back in (so it reinstalls) because it doesn't boot up on its own.
- My Power Options is set to "High Performance" so that's not the reason why my 2nd monitor isn't booting up with my PC.
- I have tried plugging in the VGA cord of my second monitor into the mother board but it didn't come up.
General Information
- The second monitor is an HP Compaq LE1711
- The second monitor is plugged into my GPU? via a VGA cord into an HDMI to VGA Pigtail Adapter (company: ATIVA), into an HDMI port.
- The main monitor (1920x1080) is plugged into my GPU?, via a VGA cord into VGA to DVI-I Dual Link Adapter, into a DVI-I port.

Picture of what I'm seeing:


I'm pretty sure I've got some of the terminology wrong (I'm not a computer expert).

Any help is appreciated!

I think this is the right place to ask this.

I have two monitors connected to the ATI Radeon HD 2600 XT graphics card (it has two DVI connections). With both monitors on everything works fine. Windows remembers which apps I have open on which monitor and so on.

However, sometimes I turn on only one (the primary) monitor. In this case Windows somehow still thinks that both monitors are there, so the apps which would open on the second monitor still do so, i.e. I can't see them when I start them, and the mouse goes easily beyond the active monitor.

Now, the second monitor is completely off - it has a real power switch. But it's possible that it still has some voltage through the connector so that Windows - or the graphic card - detects its presence. I have not tried to unplug it but maybe I should do that as well.

So finally my question - is it possible to make Windows aware that the second monitor is not in use and only extend the desktop when the second monitor is on and do that without restart/log off?

Thanks for any suggestion.

Answer:Dual monitors, secondary monitor on/off intermittently

If it's plugged in when you boot, Windows will assume it's in use and available...

No known Windoze workaround... connect multiple monitors, Windoze will 'think' they're all turned on and working - however you might find some third party software (like Ultramon for example) might be able to correct the problem...

I recently moved my studio downstairs, and the only thing that has changed is that I now use a Wacom Intuos 6" x 11" tablet. When running Corel Painter 11 the right monitor is sluggish, but the other one is fine.

For example if I drag any painter window around on the right monitor it is really sluggish, but if I drag it to the left monitor it's fine.

Monitors on same ports as before, and I did not have this issue before I moved my studio.

Driving me crazy, and I need to get back to work! Any help, suggestions greatly appreciated!

Answer:Dual monitor issues. One Sluggish monitor?

Moving the rig around could have loosened a connection, or the video card itself. Check all connections, and reseat the video card.

i've got a minor issue where some apps choose to launch on the secondary screen, rather than my primary. i believe it is because my secondary is actually to the left of the primary (it is a TV that is physically to the left of me). is there a way to tell apps which screen to launch in? i'd rather have all my apps launch on the primary display.

Answer:dual-monitor: apps starting in secondary screen instead of primary

Vista goes screwy with this sometimes - but mostly, I have noticed, when I run WMC and it opens in the window that the app is in.

Try running WMC on your TV so that it forces the app to the other 'monitor' and then hit the start button on your KB, freeing your mouse from WMC, and then go to the other monitor and close the app(s). Then close WMC and see if the app opens back on the TV or in the monitor.

I recently switched to a dual monitor set up using my LapTop/Docking Station and 2 Monitors. (I added a second monitor to my Docking Station and closed the Laptop Screen.)

I previously used a Monitor and my Laptop Screen. (The Monitor was set as Primary, and the Laptop screen as Secondary. The Monitor was set to the Sub-D on the Docking Station.)

When I had the Monitor/Laptop setup -all open applications and desktop icons stayed in place. With the two monitor set up, the applications open on my Secondary Monitor move to the Primary after Waking Up, and the Desktop icons on my Primary shift around. (I have to drag everything back...)

This is annoying, please assist...

I recently purchased a new computer that came with Dual 256MB Nvidia GeForce 7800 GTX with SLI Technology. I have two displays: a DVI connected flat panel display and an InFocus Projector connected to the DVI by a DVI-VGA converter. On my old computer, which had the GeForce 6800, I was able to view the same display on the flat panel and projector simultaneously. Now, it appears that the computer will only recognize that one display (either one -- either works on its own) is hooked up at only one time i.e. desktop, properties, display doesn't recognize the secondary monitor. The real bugger is that when I boot up the computer, both displays show the litte windows XP thingy while windows is loading. It is only after the desktop view comes up that the computer ceases to recognize the presence of the secondary monitor. Note: I DO NOT want two desktops or to stretch one desktop between two monitors. I merely want to clone my monitor onto my projector.

Any thoughts?

I have HP Desktop Tower Pavilion with windows 10, I had two HP S2031 monitors in dual mode, worked fine. One of them died, I got a good deal on a larger HP 27er monitor.  I hooked it up, they were both working fine ... it was using a default monitor
setting ... and then yesterday the computer downloaded some updates, and in doing so, it downloaded the driver for the HP 27er and installed.  The next thing that happens is the older HP S2031 starts to go dark ... like it is going into sleep mode, and
then it is totally black.  On reboot, it starts up with both monitors working, but within seconds of reboot the HP S2031 goes black again. The HP S2031's buttons do nothing, other than the power button, which turns it off and on, but that is it.  
I have done all troubleshooting, I did not even have them set up to sleep, all settings are at NEVER.  In coming here, I have done all the fixes I can find for similar  that are posted for similar issues, the Windows Key + W... nothing. 
The create new power plan ... nothing.  the device manger>display adapters>disable then enable ... nothing.  and lastly Start>Control Panel>System>Device Manager>display adapter>driver tap>update ... still nothing.  HOW
DO I GET THE HP S2031 MONITOR TO NOT BE IN SLEEP AND HAVE BLACK SCREEN.  I can not figure this out and am not finding any fix.

Ok, so I do promise that I have searched and could not find a solution to this problem.

Recently my laptop screen was stepped on ( :( ). So, only portions of the top right quadrant of the screen was still in working condition. Using this spare real estate, I set up a secondary monitor to work as my primary. While this worked for a week, the rest of the screen that was broken finally gave out and became unusable.

Here is the problem: After one restart, Vista stopped deciding it wanted to use the secondary monitor as my primary, and nothing is showing up on either screens now. How would I, without any visual display, setup the secondary to the primary again?

Thanks!

So this monitor is from April 09, and I've have no issues with it until now.When I boot it up, the monitor will occasionally be vigorously flashing on and off again. Just now, it continued to turn off and back on, and while it did, the display on the screen would change colors and even shake.I'm no expert on this, so I'm not 100% sure if it's the CPU or the monitor itself.My computer is an HP Pavilion p6210y, and its graphics card is NVIDIA Geforce 9100, and was also recently updated as of November.Also, when I start the computer, it occasionally displays the blue HP bootup screen, and sometimes it won't. When it doesn't, I notice that that's when the screen starts flashing quickly. When it has the blue startup screen, it's pretty much all good for a while.During use, it'll randomly turn off and back on continuously until the Amber light comes on and tells me that it is going into sleep mode. It says I have no connection via HDMI or VGA, when I clearly do and have checked multiple times.I would like to know if there's some sort of ongoing issue, maybe a malware, or if I just need a new monitor.Please help! Thank you!

Hi folks. New here.  Sorry if this has  been asked/answered, but I searched and didn't find it. My company got me this great new W500 laptop.  Came with minidock and external monitor. I have the monitor plugged into the minidock, and have it to the right of the laptop. Laptop is monitor #2, and external LCD display is #2.  works great.  UNTIL.... If I lock the console, and fold the laptop monitor closed (to have it power off - i.e. at lunch break, etc...) When I come back, the external monitor is now monitor #1 (has the windows task bar, Start menu, etc...) and it thinks the laptop monitor is monitor #2.  I can't figure out how to switch them back without rebooting.  It's very frustrating, b/c the 'sides' are swapped too.  Meaning the external LCD display which is physically to the right, is "on the left" as far as Windows is concerned, so if I drag the mouse off-screen to the right of the external display, it arrives on the left side of the laptop (which is physically to the left). Is there a simple solution to this?  I can't live with having to reboot every time I lock my monitor. I'm using Windows XP if that makes a difference.

Answer:Dual Monitor issue. Lock console & external monitor becomes monitor #1

My computer desk sits next to my entertainment system, and I have it connected to two monitors: the primary 22? Viewsonic LCD (DVI) and my 42? Toshiba TV (HDMI hooked in via my receiver). When I just want to browse the ?net or email, I use the primary monitor. For gaming and movies, I use the TV. For a couple of years now, I?ve had display options to always display the TV (monitor 1). If the TV was off, it would default to the Viewsonic, per the Windows feature to always default to the current monitor if only one was on. If the TV was on, it would stop feeding the Viewsonic and default to the TV, so that any games or movies would display on the TV and not cause any issues fullscreen. This way the TV being on or off determined whether the PC would feed to it or not, and I?d only turn on the power hungry TV for entertainment.

About a month ago, my monitors started behaving oddly. The PC would power up normally and load Windows to the Viewsonic, and during the load up screen the Viewsonic would power down. The only way to see the screen was to turn on the TV. This is on Windows 7 64 bit Home Premium (up to date).
Things I?ve tried:Set the Viewsonic to be the primary monitor and settings to only display on the Viewsonic. Result: If the TV is off, there?s no video to the Viewsonic. If the TV is on, it is black (as expected since I've set the monitor to receive the feed) and the feed goes to the Viewsonic.
Set the monitors to extend across both the Viewsonic and T... Read more

Answer:No feed to primary monitor when secondary monitor is off.

Was anything done to this system just before the problem started?

Have you swapped out the cables and/or tried a different connection to the monitors?

This sounds like a failure either at the video card or the viewsonic monitor electronics, so I would try swapping out the video card and monitor if possible to confirm or eliminate them as the culprit, this can include the cabling.

I had something similar happen when one of my monitors went bad.

I have an HP laptop and I have been running it with dual monitors. I finally decided to upgrade to Windows 7 and after I installed it I noticed that the built in monitor of my laptop looked strange and when I opened the display settings to change the screen resolution and set the external monitor as a separate monitor rather than a mirror I noticed that only one monitor was detected and it was the external one (Generic non-pnp monitor on standard VGA graphics adapter) and the built in monitor does NOT show up at all.

I've tried the detection button, in hopes that the computer would read the built in monitor and I could fix the problem. This did not help. I tried unplugging/replugging the external monitor to no avail. I tried restarting without the external monitor plugged in and it STILL reads the built in monitor as if it is the external one. Is there anyway to fix this? I have not tried re-installing the OS, not yet anyways.

Any suggestions ?
 

Answer:Monitor Issues - Laptop Reading Built In Monitor as if it were my external monitor.

Only thing I can think of is to disconnnect the external monitor, uninstall any monitors listed and then reboot and hope the computer installs the correct drivers for the laptop monitor.

I have a Dell P-4, 3 GHz with 2 GB Ram and an NVIDIA GeForce FX 5200 video card (dual output, one analog and one digital). I have been using one monitor plugged into the analog port. Now I am adding another CRT monitor, also with analog plug and using a DVI to analog adapter. There is a built-in video out (on the motherboard maybe?) but it was covered when the computer came from Dell and I vaguely recall a warning to leave it alone, so I haven't messed with that. OS platform is Win XP with Service Pack 2, auto security updates, Windows Defender, TweakUI (ver 2.10.0.0) and Norton Antivirus.

Help instructions say:
Right click desktop and choose Properties > Settings tab > secondary monitor icon. This desktop is not showing me the secondary monitor icon.
It shows a single monitor and the message "Display: Default Monitor on NVIDIA FX GeForce 5200 (Dell)"

On my other computer (laptop) I have used the dual monitor feature and never had a problem.

I have tried or checked:
- "All programs" for an NVIDIA program to run or documentation
- The analog output on the video card works and I tried both CRT monitors individually to verify each monitor works
- Device manager > Monitors, updated driver, including going to Windows website.

Answer:Win XP (dual) "secondary monitor icon" missing from Settings tab

You cannot use DVI & analog output at the same time with a NVIDIA FX GeForce 5200
I know it says you can but, you cannot

well you can but you need a DVI monitor NOT a DVI to analog converter as that loops back & disables the other outlet

Hi all,
i always had a dual monitor system. My Previous setup was a 1920x1080 main monitor, and a smaller 1300x... monitor as my 2nd monitor. I had no issues at that time.
Now i bought myself a new Monitor, a BenQ RL2455HM in 24". And here my problems suddenly starts....

1. if i scroll up and down on websites (using Firefox) it feels wrong, it's not very smooth and sometimes i get a "flickering" issue while scrolling.

2. my desktop doesn't work like it should. It seems like windows doesn't know when the taskbar ends, so that the name of the icons are unter the taskbar, and therefor not readable anymore.
Also on the last row of desktop icons (the bottom one) aren't working like they should. I can only use the First 4 and the last icon slots. The other slots aren't useable (can't place any icons there.
I really really hope that u guys can help me out.
Here are my computer specs:

GPU: 4096MB Sapphire Radeon R9 290 Tri-X
Windows 7 64bit
RAM: 16GB Corsair Vengeance Blue DDR3-1600 DIMM CL10 Dual Kit
CPU: Intel Core i7 4770K 4x 3.50GHz So.1150 BOX
Old 2nd Monitor: LG W2443T
New 1st Monitor: BenQ RL2455HM

I tested with 2 cable layouts,
First Try: Both with DVI cable.
Second (and current) Try: 2nd Monitor with DVI and the new 1st Monitor with a HDMI connection.

I also already completely uninstalled my AMD Drivers - and installed the newest stable version 14.12 Omega with CCC.

Both Monitors run with native resolution 1920x1080

Answer:Dual Monitor Issues

Is the problem now on both monitors, or just the new one ?

Test with just the new monitor, still problems ?

Return it.

A second monitor and your resolution setup to extend these displays should not give you any problems, and there was no need to change any drivers.

Run windows update, there is sometimes a monitor driver, it may help.

Got a 22" Westinghouse and a 19" HP monitor hooked up to a 512 MB X1600 card. Everything is set-up and working fine except for when I start the computer up and the Westinghouse resets itself below the native resolution. I looked at the Setting menu on window's properties and it recognizes the HP but shows the Westinghouse as a Plug and Play monitor. Could this be the issue? And how do I tackle this annoying glitch?

In case you're wondering, I can set the Westinghouse back to it's native resolution after it resets itself. After I do this every time I start-up, I don't have to do it again until next time.

Answer:Dual monitor issues!

Hi, and welcome to TSG.

Is the computer switching to a different video resolution during start up? If so, the new resolution may not be compatible with the Acer AL2216W. Does the monitor show any kind of an error message before it stops working?

If you are using a simple splitter cable without any kind of active electronic amplification and the computer is switching to a higher resolution at the end of the startup cycle, there is also a possibility that the cable is attenuating the higher frequency split signals to the point that they can no longer properly drive the Acer AL2216W. You could check for this by connecting the single monitor to the computer without using the splitter cable.

I realize dual monitors should be pretty straightforward, but I've run into some interesting issues that I would appreciate some insight on.
I am running a Windows 7 computer with An NVIDIA GeForce GTX 285 video card. The video card has two DVI outputs.

Running a two monitor set up, the 1st an 6 year old 19inch AOpen monitor with VGA or DVI inputs, the 2nd a 5 year old Samsung LCD TV with VGA and HDMI inputs.

I was running a DVI cable to the 1st monitor and a VGA cable, with a DVI converter at my computer, to the second. Everything worked fine. Then I moved my set up to a new room and had to move the second monitor further away. I decided, since I needed a longer cable anyways, I would try some other options.

I bought both a 15' DVI to HDMI cable and a 15' DVI cable.

I started using the 15' DVI to HDMI cable to the Samsung TV and everything worked fine for about 2 months. Then one day my TV stopped recognizing the input from the computer. It would not even allow me to select the HDMI port as if nothing was plugged in. This is particularly strange since my computer still recognized the TV and acted as if it was working fine. I tried ever variation of rebooting I could think of, TV on first then computer, Computer on first then plug in TV, and so on. Nothing would recover my picture. (I also verified plugs were properly plugged in an all the basic stuff)

Hey guys, first thread/post what have you. Only doing this because I'm completely out of ideas and have pulled out all of my hair.

http://prntscr.com/4kgar3 Those are my basic specs.

I know enough to have fun with PC's but i'm sure you all leave me in the dust. I have always ran two monitors on my desktop up until about a year ago, one of them broke and i never bothered to buy a new one. Just used the one i had, which used to be my secondary monitor.

Now when I plug in a secondary monitor, I can't get a signal on it. They both plug into DVI-D ports. And I'm sure both ports work, cause i've played around with the settings to make the display show up on both (individually) The second monitor is a brand new RCA with DVI to HDMI cable that has never been on this computer.

I've seen posts about deleting display setting for vista because i've had about 6 different monitors on this PC in its lifetime, but nothing for windows 7 that seems to work. Do i have to factory restore. I've gone through the right click screen resolution option and the Nvidia control centre option, i've updated my nvidia driver and my AMD driver.

This used to work just fine with 2 monitors. I thought this might be the issue. My original secondary monitor became my primary monitor. And now won't switch over properly. ( i've changed the monitor to make this my main monitor in both windows and nvidia control centre )

Hey folks, I just got myself my second monitor, a Samsung SyncMaster 2232BW, and I'm having it alongside my old monitor, a Samsung SyncMaster 173T. Anyway, I've been having some odd issues I'm at a fault to understand with this. Basically, every time I turn off my computer and boot it up again, windows starts up in the lowest possible graphical mode, meaning, what 8 colors(?) and a *very* low resolution. On top of this, it's only displayed on my old monitor, and the new one is completely blank. And when I try to alter any graphical options under windows desktop preferences, it says that my graphical driver is out of date. Sure, no problem, I download the latest driver for my GPU and install it, restart the computer like the installer prompts me to, and everything just works after that.

Or atleast, until the next time I turn off my computer. Then everything repeats, except that I install the exact same drivers again, having it overwrite some files (which doesn't surprise me) and it works yet again. So basically I'm having a hassle having to install the same drivers I already have installed and restart my computer once before I can use it. So, please, I would really appreciate any help as to how to avoid having to do this every single time I boot up my computer

I have issues getting a second monitor to work.
At startup I get a picture on both ( Window starting up... 4 little dots circling..etc)
But as soon as I reach my "Log-in page" my second monitor goes black.

At monitor settings it does not even show the option of dual monitiors.

The computer this concerns is a Acer Veriton N281G (cheap and cheerful). It has a Intel GMA 3150. I run a split cable from the computers VGA to both screens VGA`s.

The fact that I do get a signal on my second screen at start up brings me to think the problem is within Windows. Am I correct and WHAT is the solution???

Many thanks!

Answer:Dual monitor issues!

susidus, welcome to the Seven Forums.

Hope you're not trying to get the monitors to run in extended mode, as when using a VGA splitter all you will get is clone mode (same thing on both).

And no it isn't a Windows problem, the Intel graphics in that thing likely can't handle running both off of a single connection. It is also the Intel driver that is stopping both from running once it is loaded.

Hi guys, I've tried searching the web for the issues that i've been having but i can't seem to find a clear solution. I have a laptop with a GeForce GO 7900 GS video card, and my secondary monitor is a 19" samsung LCD TV (not a legit computer monitor). I understand that things won't be perfect on the TV because TV's are simply don't have resolutions like computer monitors. But anyways, i got the dual monitors to work with an s-video cable but i'm still running into some problems. Say if i wanted to watch a movie on the TV, i would drag winamp or WMP onto the TV, but when i make it fullscreen the video becomes fullscreen on the laptop display not the TV. At the same time while the laptop is fullscreen with the movie, the TV now has some of my icons that were on my laptop. Is there a way i can fix this problem?

Simply put:

How can i make a media player stay fullscreen on the TV and not the laptop? How can i stop the media player from swithing over?


Thanks,

They work better, but I must warn you that doing like your doing above does not always work all the time. I've tried it myself. Then you run into problems. Does the 19 LCD HdTV have VGA? If it does then use it as a Monitor Extender. So this would give you wrap around view.

But it registers both monitors running through it, and when i click on the second monitor, then click on the box that says "Extend the desktop onto thin monitor", it asks if i would like to keep these changes? I hit yes, but nothing happens. The box is unchecked, the power light on the monitor is still orange, and i cant move anything onto it. If anyone could help that would be great.

Hi everyone, didn't know where to post this, so went with general hoping someone can help as small stuff like this really bugs me.

I've just setup a 2nd monitor, a shiny new 30" dell, I'm using my old 28" hanns.g as my main, with desktop icons, start bar and everything on it, thats on the right hand side, with the 30" on the left. The trouble is, is that when I changed the monitors around so the mouse could go from left to right within windows, the icons where shifted to the left hand monitor the 30". I've managed to drag them back accross, but there is now a space above the startbar where I can't place any icon's, those that are placed there are moved to the monitor on the left. I also can't scroll across to the lef hand monitor at the bottom of the right hand monitor. I have placed the right hand monitor on a stand so the top of the monitors match close enough in height.

The monitor on the left, the 30" is on max resolution of 2560x1600 and the hanns.g on the right is on max resolution of 1920x1200, is there any fix for this?

Ideally I'd like to be able to scroll across from the bottom of one monitor to the bottom of the other monitor and be able to place my desktop icons at the bottom of the screen, which I can't do on the 28" atm.

PS: I'm using dual link dvid for the 30" and vga for the 28"

Hello. I actually have 2 issues I am dealing with. My OS is XP. Here goes..

I was having trouble while on-line. Internet Explorer would close because it kept encountering problems. I called Earthlink, they checked on their end and said things were fine and we went through the wizard and it had grayed out the option for dial up and defaulted to broadband. I have dial up. When we try to add a number for dial up it comes back with error 711: a configuration error on this computer is preventing this connection. So Problem #1 is, I cannot get on-line as the Earthlink is not seeing I have a modem installed. Earthlink concluded it must be an OS error and suggested I re-install my OS. I tried to do this and got 2 error messages along the way. One said c:\windows\sisagp is needed. The other said GET IUMS could not be found and said MSDART.DLL. I had to cancel to get by those 2 messages but it appeared as though it had installed but thank goodness it must not have installed because it didn't wipe out everything I had on there. I should never have done the reinstallation because I hadn't backed up. The Earthlink gal made it seem like no big deal and I hate to say I am a little bit beyond a beginner. I did try to reinstall the Intel modem but no luck with the problem. I did not uninstall it though.

Sorry if this is in the wrong place, wasn't sure if it should be in the forum for GPUs or Hardware or not.

I have 2 monitors (1920 x 1080) connected to my Nvidia GTX 770:

BenQ XL2430T (Primary)
BenQ E2420HD (Secondary)

I currently have my XL2430T (Primary) set to 120hz and my E2420HD (Secondary) set to 60hz both connected by DVI.

This is the first time I have had more than a single monitor so sorry if this is a stupid question.
I have noticed that if I have a game running on my secondary monitor (60hz) while I have anything else on my primary monitor (120hz), I get FPS drops for that game.
If I play the game on my primary monitor (120hz) while having anything else on my secondary monitor (60hz) there are no FPS drops.
I also get no FPS drops if I play a game on my secondary monitor if I lower my primary monitor from 120hz to 60hz and have both monitors running at 60hz, and I know that it seems stupid to be playing a game on the secondary monitor but I am still curious.

So in short it seems I only get FPS drops with games on my secondary monitor (60hz) when my primary monitor is set above 60hz.

I guess my main question is, should this be happening? Is this just the limit of my GPU or is there something else possibly at play here?

Answer:New monitor (Dual Setup) FPS issues

My guess would be that the graphics card has to work harder when the refresh rate is set to 120 Hz. Two different refresh rates probably causes the GPU to work even harder, resulting in lower frame rates. Also, the secondary monitor is most likely not given priority by the system, again leading to lower frame rates.

Is there a specific reason that you need to run your primary monitor at 120 Hz? Does your frame rate on the primary monitor increase if you run it at 60 Hz? Myself, I would run the monitors at the same refresh rate to avoid potential stability problems, and situations like the one you are describing. But that's just me.

I've never ran into that one before, but multi-monitor configs seem to be the most readily breakable video setting.

I would probably try uninstalling your ATI drivers and upgrading to the latest version. When you uninstall, make sure to use Guru3D - Driver Sweeper (Setup) download from Guru3D.com or some similar application to completely clean out the driver settings.

I'm having issues with my Dual monitor set up and not sure if it has anything to do with the ATI Radeon 3000 graphics card. I've gone to AMD support to download the the latest driver for Win10 and keep getting message stating ( We are unable to find a driver for your system). I have the extended display but when I click on the browser on the 2nd screen it opens on the 1st screen automatically. 2nd screen is blurry as well !

Processor:
AMD Athlon(tm) II X2 260 Proc
Graphics:
ATI Radeon 3000
OS:
Windows 10 64-bit

Answer:Dual Monitor issues with Win10

Copy-pasting this from another thread I just put it in, but I had this same problem just earlier and managed to fix it. Give this a try:
Open the AMD Catalyst Control Center (essentially the options/settings program for AMD graphics cards).Select 'My Digital Flat Panels'.Select Properties.Use the dropdown menu to select the screen you're having issues with.Under Preferred Scaling Mode, make that Maintain Aspect Ratio is selected.

I'm not sure whether this is a new thing with Windows 10 that it automatically switched me to upon upgrading, or if it was an old options that doesn't work properly with the new OS, but when I opened the options I saw I was set to 'Scale Image to Full Panel Size', and changing to 'Maintain Aspect Ratio' fixed my blur issue.

Hope this works for you!

I have two monitors I'm trying to set up on my old PC. My system is running two EVGA 560ti in SLI, with a mini-HDMI to HDMI going to the newer Viewsonic, and Mini-HDMI to DVI going to the older Dell monitor. I can get them to both display, but then if I let the system sleep, the primary monitor bugs out and goes black. Sometimes I can get the screen resolution window up on the secondary monitor, and when I can, I can usually get the problem resolved by changing the primary to portrait and back again, or changing the resolution. The other way the screen goes black is if one of the monitors is unplugged from the input, and I plug it back in, it will make the other monitor go black. What the heck is going on? I've reinstalled the video drivers twice.

Answer:Dual monitor issues, screen going black.

After I had updated my drivers ~2 days ago I started experiencing a strange problem with my monitors. After turning them back on one or both of them would say DVI- NO SIGNAL. To attempt to fix this I rolled my drivers back and then updated them through the device manager instead of the GeForce GUI since it was having issues. I have also removed the latest programs that I believe would be causing issues with regards to drivers this being nGlide (A driver wrapper used to run older games meant for 90s era graphics cards). Currently my main monitor (ASUS VG248QE if it matters) is working fine but if I hit the change source button on my second monitor (Samsung SyncMaster 220WM if it matters) to attempt to get it to draw properly, my main monitor will stop drawing and then only if I hit Source and the up arrow button on my second monitor a few times will the main monitor start to draw again. The only thing that I can see on my second monitor is the blue power light flashing in a somewhat random patterns so I have no idea what it is trying to set as the source. I have tried reconnecting both of the monitors to see if there was an issue with connection but they both seem to be fine and when I open the display manager windows is recognizing both of them correctly. If you could offer any advice it would be appreciated. Also if more information is needed please let me know what I should provide.

Thanks in advance

Hello everyone!

I've recently bought a new rig and decided to go with Vista Enteprise 64-bit version on it.

I currently have a 30" Dell monitor and a 19" Packard Bell Maestro 190W setup that I used on my previous XP rig.
Now, when I try to use my PB Maestro 190" Screen on the Vista machine, I get no signal. I can detect the monitor through the ATI Catalyst program but it cant it to work.

The monitor works and shows stuff when I reload the computer, but it goes "No signal" just when Vista Loads...
I have downloaded Powerstrip and another monitor program to try and force it to 1440x900 settings, but still no signal.. Even wrote my own drivers for the screen with a fixed resolution 640x) but no luck.
I plugged in my LCD TV instead and it worked like a charm! So i quickly switched the cables between the second 19" monitor and the TV and bam! I got the second monitor up and running!

But I had to reload the computer and I lost the output, tried several times again to repeat the procedure with plugging in the TV and then the monitor.. no luck...
The only thing I havent tried yet is to use a VGA cable instead of the DVI one..
I'm running the lastest ATI drivers (9.3)..

Just find it strange that it can detect the screen, just not send the video signals to it..

Vista installs the second monitor as a "generic pnp monitor".. And I cant seem to find any drivers on this packard bell monitor on the internet.
Anyone got a good advice ... Read more

I have a Lenovo ThinkCentre M73.  I received an email from Microsoft advising my Windows 10 upgrade was available.  I checked and it showed my system was compaitble with all requirements for Windows 10 so i went ahead and did the update.  I operate with dual extended view monitors and can never go back to using just one screen.  After my system restarted, Windows no longer recognized my second monitor.  It wouldn't even detect the 2nd screen.  After TONS of hassle and having to go into the actual Microsoft store to get my system completely restored to Windows 8 (there were issues with the admin rights that could not be fixed even with remote assistance even though I am the only user on the computer and there were no other profiles created), I was advised that the display driver/graphics card driver had not yet been updated to be compatible with Windows 10.  And until it is updated, my 2nd monitor will not be recognized and I cannot upgrade to Windows 10 until then.  My question is when will the driver be updated and how will i know when the necessary update that allows Windows 10 to recongize dual monitors has been added to the updated driver since everything already showed i was Windows 10 compatible?  The driver in question is for the Intel HD Graphics 4600.  Thanks!

So I have a few issues with my Dual Monitors with Windows 8.1.

Drivers are all up to date, it's two ASUS Monitors, and I have some odd quirks I want to fix.

1) When I press the Start button to get to the Live Tiles, If I do it on one monitor, and then try to do it on the other, it switched the start screen with the tiles to the other monitor. I want to be able to have the start screen and live tiles open on both screens. It was working fine, and then it stopped all of a sudden.

2) Is there any way I can make certain programs load to certain screens? As I stated with the above issue. If I have IE on the right screen, and then open start screen on the left screen, and then try to open start screen on the right screen, it moves IE to the left and puts the left back to my desktop.

3) I know I could search for it, but I figured I'd ask for a simple response while I'm typing this, how can I set it up so that both of my desktops have different backgrounds?

4) When I put my cursor into the top right side of either my left or right monitor, the charms show up, and the same if I put my cursor in the top left on either monitor it shows what apps are running, is there any way to make it so the charms only show on the right monitor and the apps only show on the left? So I can go either all the way to the left or all the way to the right, I find sometimes I accidentally hit the charms when trying to go to my right monitor and it won't let me, it's annoying

We have recently replaced some older PC's in our accounting department and the users need to use a dual monitor setup. We have mini-pci video cards that were installed in the older IBM models and they worked perfectly. I have tried moving these cards to the new machines but, try as I might I am unable to get both the onboard video and the PCI video card to work at the same time. If I select automatic in the video setup in the BIOS, the onboard video is not seen by the operating system (XP sp2). If I select the onboard video, the OS will not see the addon card. I have upgraded the BIOS to version 5CKT48A, but still having the same issues. Is there a fix for this? Previous models from IBM/Lenovo were relatively easy to configure, not sure why a basic function isn't working. Thanks for any help!

I've recently updated from Windows 7 to Windows 8 on my Dell XPS 15 laptop. I normally run a dual monitor setup with my 33" monitor and I am quite fond of watching netflix on the secondary monitor while gaming/doing school work/blogging/reading news/etc... however I'm noticing two things that I would like help with:

1) there is no way to run Netflix on the non primary monitor.

2) there is no way to allow the netflix app to keep playing while running another program (non app). It just exits out.

Are there app settings to get around either or both of these? Some help, please!

Thanks!

Answer:Issues running apps with Dual Monitor Set Up

can you describe your monitor? is it VGA? is it HDCP compliant? the Windows Store Netflix app requires that the graphics card driver AND the monitor be HDCP-compliant. VGA is considered an "unsafe" connection (unsafe in that the contents can be copied) and most VGA monitors are not HDCP-compliant. And none of the old VGA monitors are considered HDCP-compliant. Part of the reason why VGA monitors are extinct in this new DRM world.

in fact, this HDCP compliancy is breaking a lot of systems that have older VGA monitors where the streaming content is encrypted and fail to start. If you have DVI or HDMI displays, they are most likely HDCP compliant and you see less people having issues with Windows Store apps with these monitors.

I have a 3 monitor system. 2 of them are DVI and the other is VGA. I can choose any to be the primary display and have Netflix on any of the other monitors. However, on the VGA monitor, the Windows Store Netflix app will not run any material. The app will run and I can choose the show. But when it gets near 100%, it stops at the security checkpoint and errors out. With a web browser or with Windows Media Center, the VGA restriction is less (likely because copying the content is less than desirable from these sources) and they will allow the content to play.

Windows Media Center is the best way to play Netflix on a VGA monitor. Especially if you have a nice Windows Media Center remote. You can browse Netflix like a TV.

Hi All,
We've installed a number of Dell Optiplex 3040 machines running Windows 10 pro x64 at a customers site with dual Dell E2316H monitors connected directly via VGA and display port cables.
Two users have reported daily issues of the monitors flickering black and going off before coming back a few seconds later.
We've tried updating the graphics driver, firmware, changing power settings and swapping out cables for new ones - none of this has made any difference.
We've also asked the users to move desks and connect to working monitors. The issue followed the PC's and occured on the other monitors.
We only have remote access to the machines at the moment so Dell won't help troubleshoot.
I've seen other posts reporting the same issue with the Optiplex 3040's so wondering if this is a known issue.
Any suggestions would be much appreciated.

Answer:OptiPlex 3040 Dual Monitor display issues

Can you Private Message me a service tag of one of the systems that is having this issue? Also does it seem to matter what port/monitor is doing it, or are both monitors flickering?Best regards,Brad

Good evening!

I'm not sure if this is the appropriate place for me to post this, but I had a couple quibbles with dual monitor support on both Win10 and Win10 Insider preview. There was the nice addition in Windows Insider Preview of having a clock on both your monitors (whereas that wasn't the case in Win10) but not having the option to have the tray icons on both monitors is KILLING me. I am a gamer, and generally use my second monitor for generic stuff, i.e., Steam friends/chat, web browsing, and launching games or other things from the tray, using my second monitor, while I am in a game. Now, my problem arises because I have to set my second monitor as the main monitor. That makes games launch on that monitor by default, and I use DualMonitorTools to do things like lock my cursor to one screen, switch windows quickly from one screen to another, etc. Those functions may be rolled into Win10 by default, but when I was using 7/8/8.1, I needed to use third party software to be able to launch what I needed on my main monitor while still having access to my tray icons and taskbar. The games I play, I launch on the smaller, second monitor (which is my "primary monitor" in Windows settings) and then use DMT to flip them to my REAL primary monitor. This doesn't work with all games, not to mention it is pretty clunky - when it should be easy.

I am not sure if I explained my issues well enough but in summary, how about an option to have dual splash areas for tray icons?

Answer:Dual monitor issues with taskbar/tray icons.

The setting you are looking for is in Settings > Personalisation > Taskbar:


Another option is simply to drag Taskbar to secondary display. In screenshot below you can see that display 1, in my case laptop's own display is the main display but the Taskbar is shown only on secondary display, positioned vertically at left:

Hello,

I just got myself a second monitor and am having issues setting it up. My original monitor is an HP 2311x with a resolution of 1920x1080, and the second monitor I just got is a gateway something-or-other with a resolution of 1920x1200. My graphics card is an ATI 5770. I have the HP monitor's source as DVI off of the graphics card and the gateway as HDMI off the graphics card. When I set both monitors in extended mode to their native resolutions I get this weird color/resolution issue seen in the picture.



When I set them both to 1080p the gateway monitors color turns correct but obviously the resolution is wrong. Any help? Thanks in advance.

Answer:Dual monitor setup resolution/color issues

Hi,

Welcome!

Just saw your post and hope you resolved it already. But have you used the Calibrate Color feature?
start > control.exe > display > Calibrate Color
Note: this requires admin priv's.

Are you sure DVI and HDMI are supported simultaneously? On the GeoForce there are issues there and some HP monitors have seen mixed results with that. D-SUB and DVI or D-SUB and HDMI is common.
Clock rates have to independently correlate on each output connection. I would suggest digging into the ATI specs a little more.

Sorry if I am misreading what you mean by "obviously the resolution is wrong".

NOTE: I placed this in windows 7 forum issues because I believe this is a Win7 issue and not a video card issue. If I am mistaken, I'm sorry.

Alrighty, I guess I'll get this started off with what my issue is in it's most basic form. I have a dual monitor set-up on my system, a 24 inch widescreen dell LCD monitor, and a westinghouse 32 inch LCD tv, using it as my secondary (movies, etc).

My issue is that when I'm playing a game, like WoW on my main screen (24 in) and I have a video or movie playing FULLSCREEN on my secondary monitor (32 in tv), My video will completely cut out on both monitors. My system isn't locking up, because i can continue to hear the sound from the movie and game. It is random on the amount of time before it cuts out, I may be able to watch a whole movie, or it may cut out after 5 minutes, it just varies, and when it does I have to hit my reset button to do a hard reset on my computer and let it reboot. I have no idea why this is occuring.

More background info: I've always been an nVidia fan, and was using a geforce 8800gtx in my system, windows xp, running dual monitors, NO ISSUE like the one described above. I could full screen and never have an issue at all. Since then I upgraded to windows 7, and the issue started happening. After rebooting and checking the event log it stated that my video driver stopped working. Well, I assumed maybe my card was starting to die, and this was the cause.

I'm using a T430s and a mini dock plus series 3. This is the dock with the dual DVI, dual DisplayPort, 1x VGA. I do not use the laptop's built-in screen; just the 2 external monitors. Intel HD4000 graphic chip and Nvidia Optimus/ I previously had 2 20" monitors with a 1680x1050 resolution using DVI-to-DVI. They both worked fine. I upgraded to 2 24" monitors with a 1920x1200 resolution. The laptop is not recognizing the second monitor. I have tried:dual display port (dock side) to mini display port (monitor side): only 1 monitor recognizeddual dvi (dock side) to HDMI (monitor side): only 1 monitor recognizedI ruled out monitor and cable problems by swapping...each by itself works fine. Looking up specs, I believe this resolution should be supported by DP or DVI. Can anybody confirm that this is a supported config? Any ideas what is wrong? UPDATE - I did try 1 DP/mDP and 1 DVI/HDMI: this does work. However, its not an ideal solution because it would interfere with the monitors ports which I want to use for a second PC. UPDATE 2 - OK, now I am beyond aggrivated.

Answer:Second monitor not detected: T430s with Mini Dock Plus Series 3 dual external monitor

Fixed; was a driver issue. Problem seems exclusive to a Dell u2415 on DP port 1 only of the dock or to the laptop's DP port (at least for the couple monitors I tried). It's possible it could affect other monitors. My starting point: 9.18.13.4535 / 9.17.10.2843 (Nvidia /  Intel) The latest driver from Lenovo is 9.18.13.4535 / 8.15.10.2725. I'm not sure how i have a slightly newer Intel, but that's what it was. I couldn't install the Lenovo driver. I also couldn't install a newer driver from Intel (10.18.10.4276). In both cases Windows or the Intel installer stopped me saying the mfr provided the drivers and that the installed version was up to date. I worked around by first rolling back the Intel driver. The manual (.zip) install of the latest intel driver worked. This immediately fixed the Dell u2415 on DP port 1 and laptop's built-in DP port.

Hi,

I am using windows 10 pro with 3 monitors attached to a GTX770.
2xDell U2715H monitors (1440p) - work monitors
1xPhilips 1080p monitor - client monitor.

Two monitors are used all the time for work in a dual monitor setup. The third monitor is placed away from me facing clients. When I want to show stuff on the pc to the clients, I will open the display settings and select the duplicate one of the 1440p monitors to the 1080p monitors. The display of the 1440p will scale down to 1080p. When clients leave, I toggle back the settings. The third display is only on when clients need to see something as it is a hassle for clients to come see the stuff the other side of the desk.

Is there a way to automate this process? Maybe some sort of macro/hotkey which I can configure the commands so that I don't need to go adjust the settings every time. I would just like two macro/commands that turns duplication on and off.

Thanks

Hi.

I recently got a monitor from one of my friends saying that it was broken. Its a Dell 19in LCD. I have my main monitor a 22in Samsung wide screen So i just plugged it into the second DVI slot on my graphics Card. When i went into the display config i set up dual monitors just to see if it was working. The dell monitor would blink up then quit on me.

When i was messing with the Display settings I made the Dell. Not my Samsung the Default Monitor. I unpluged the broken Dell and restarted. Now my computer regognizes the Samsung as the second monitor and it just shuts it off and recognizes nothing as the main.

I managed to get it into safe mode and it recognized the samsung but every time i try go back to Normal Start the screen is blank.

How can i get it to recognize the Samsung as my main?

Hi,
Just as the title says, I'm having a slight issue with my dual monitor setup. I regularly need to keep my computer on while not using it, so I usually turn both screens off when I do so.
My problem occurs when I return and turn both monitors on. When I turn on screen 2, nothing bad happens, and there is no change in the position of the windows I had open on both screens. However, when turning on screen 1, both screens refresh, and afterwards all windows that were open on screen 1 are now in the same positions on screen 2. I have had this problem since I installed the second screen about half a year ago.
I know this is a minor issue, but the number of times I've had to rearrange the screen is annoying. Is there any solution to this? Might it be something in the Win 10 display settings? Thanks in advance!
I have Win 10 Pro (10.0.10586 Build 10586)
Screen 1: Dell U2715H (miniDisplayPort) (2560x1440)
Screen 2: Dell U2713HM (Digital) (2560x1440)

I have the displays set as 'Extend these displays'.

Answer:Dual monitor issue - programs switch screen when monitor turned on

I'm not sure I can help, I haven't had that problem. I run 3 monitors. I assume you have gone to display properties and arranged the monitors as they are physically located and set one of them as primary display. Make sure each monitor has 'Extend Display to this monitor'. You should do the same in the Nvidia Control Panel. That's really all I had to do with mine.

Good evening,

I work for a law firm that uses Dell Optiplex's ranging from 745's to 790's with all inbetween [745, 755, 760, 780, 790]. Our NJ satellite office also has these Dell model ranges, but all of them have Windows XP SP3 installations. These machines generally either have the Intel Graphics Media Accelerator Drivers or the ATI Radeon HD 3400 series card/drivers for those models that do not have an available display port. With that said, all machines have dual monitor setups as well.

The issue, put simply: almost a 1/4 of the PC's in our NJ office lose their second monitor on almost a daily basis, where we either have to re-extend the desktop to the other monitor or we have to play the unplug/shutdown/re-plugin game with the display port adaptors.

We're about to run a report containing the following information for the affected machines: OS, BIOS, Video Chipset, Connector Type [VGA2DP, DVI2DP, DP2DP], Power Save Settings. However, I'd like to throw this forum post out there to see if anyone knows any specific Windows XP Pro SP3 issues that exist with utilizing dual monitors on these machine types and/or how to resolve them.

Running dual monitors in Win 10 and when going through the Color calibration steps on monitor #2 (Control panel / Display / Calibrate color) the settings stick as long as the 2nd monitor is active.

If I switch to single display (Windows Key + P / PC Screen only) then the 2nd monitor loses its color calibration. Also anytime I reboot my PC (Even if I have both monitors active) the 2nd monitor loses my calibration.

The 2nd monitor has a fairly strong bias for the color Green so I can always tell right away.

I'm probably overlooking something and was hoping someone might of dealt with this before

Hi!
I recently bought a DVI cable to plug my external LG monitor to my laptop to run nVidia's DualView (stretch format) across the two monitors. I'm using a beta driver (169.04 from laptopvideo2go.com), and when I enter nVidia control panel and go into the setup additional monitors tab, it only lets me choose "choose only ONE monitor". So I did that just to test that my monitor was plugged in right, and it worked. So I KNOW that my monitor is working and is being recognized by Vista. But when going into display settings byt right clicking on my desktop, it also only recognizes 1 monitor. Is it my beta display driver messing my Vista up? Or what could it be?
Any help would be greatly appreciated

Thank you
 

Answer:Solved: Dual monitor in Vista not working. Only showing 1 monitor.

for drivers to work properly in vista i'm pretty sure you have to have signed drivers, since it's beta are you sure they are signed?

I have an ATI Radeon 4670 card. I have not had trouble getting it to "Dual Display" in the past. Usually I wanted to do an extended display. I am now trying to get it set up with my HDTV with HDMI. I have added the Realtech drivers and HDMI adapter to the video card and have been able to get HDMI and digital sound to the HDTV, I am trying to get the two displayed as clones.

The problem I am having is after getting Catalyst to display the HDTV, I have lost the image on the monitor. In the process of trying to get it back to both displays I have accidently made the HDTV an extension of the monitor. Which is really a cluster as I can not get to the control panel to make any changes. All I have is the extension showing on the big TV but none of the controls. I tried rebooting in safe mode but was unable to access the catalyst control center as it did not boot in safe mode. The big plus is that in safe mode both screens are visible, but I can not undo the Catalyst settings. I am now running a system restore which will take me back to tomorrow settings, which is not ideal but better than not being able to access anything outside of safe mode.

How do I get the TV and monitor to display at the same time?

I've been running a multi-monitor setup for a while now, with an ASUS VG248QE 144Hz monitor as my main, and one or more spare monitors as secondary displays. I've set the ASUS monitor to 144Hz without issue in the past, while the other monitors stay at 60Hz.

The other night, Windows wanted to update. I figured it was the usual patch session, so I let it do its thing. However, after restarting my computer, I noticed that my ASUS monitor would only operate at 144Hz if it was the only monitor plugged into the system. When I try to set it higher in the Nvidia control panel, it just reverts back to 60Hz after applying changes. I updated my graphics drivers (though I was only one version behind) and even sought a special ASUS driver for the monitor to resolve the issue, but nothing has helped.

Did Windows recently add a forced refresh rate sync between all monitors recently? If so, that really sucks because I only own one 144Hz monitor.

Answer:Dual monitor setup locks 144Hz monitor at 60Hz

Are you sure the other monitors are independent (dual or multiple mode) rather than cloning the main monitor? If they clone the main monitor, then this explains the 60Hz refresh rate, as all settings (resolution, color depth, refresh rate) should be common for all monitors and the others can only do 60Hz.

Running dual monitors in Win 10 and when going through the Color calibration steps on monitor #2 (Control panel / Display / Calibrate color) the settings stick as long as the 2nd monitor is active.

If I switch to single display (Windows Key + P / PC Screen only) then the 2nd monitor loses its color calibration. Also anytime I reboot my PC (Even if I have both monitors active) the 2nd monitor loses my calibration.

The 2nd monitor has a fairly strong bias for the color Green so I can always tell right away.

I'm probably overlooking something and was hoping someone might of dealt with this before

Answer:Dual monitor setup, Monitor #2 keeps losing color calibration.

I am not really an expert here, but I am wondering do you set the default calibration as well as the current calibration? I have always done that so I can't tell you whether it will cause your problems if you don't set it, but I can tell you that I have never had the issue you are having.

Hi,we have multiple M93p tiny computers causing problems in dual monitor setup (VGA / Displayport->DVI). Our users (already >5)  keep telling us, they leave their workplace, return, then DVI attached monitor if off and they do not find a way to turn it on. This is true; the only workaround that has been found by our users is to bring Win7/32bit into standby mode and awaking it again.Needless to say, we turned all windows energy saving options off (computer standby/hibernate, monitor turn off). Still the problem appears.Maybe there is something wrong with DVI power/DVI signal?- Monitor independent, as far as I can see- Independent from Windows energy saving modes- BIOS updates did not help[todo]: Try Intel/(AMD?) drivers, let users test. I haven't seen exactly when the monitor turns off because it is reported by users. I had a testing machine, but was not able to reproduce. http://forums.lenovo.com/t5/A-M-and-Edge-Series-ThinkCentre/Dual-monitors-problem-VGA-and-Displaypor... is related. Anyone? Thx

I am looking for help with my new x201 (3626 A57) with docking station.  I am running it with an external Lenovo monitor using the docking base.  I have them set up for dual mode when in the dock.  I undocked by pressing the button on the left of the dock, waited for the green light to stop flashing, and pulling the lever.  After using the laptop successfully in undocked config, I replaced the laptop on the dock.  From that point until I reboot, the the monitor did not recognize the laptop and did not display a dual mode screen.  I tried Fn + F4 for sleep mode and also unplugged the external monitor.  It would be great if this worked seamlessly in or out of the dock. Any ideas?  Am I doing something wrong in my undocking?













Solved!

I am having troubles getting my dual monitors back.
Initially had a GeForce 8400GS 512MB PCI video card and was using the on board video (Biostar G41 M7 MB) for dual VGA monitor setup.

I've installed a Radeon HD 6670 1GB PCI-E video card with monitor one setup via DVI to VGA adapter on output one and 2nd monitor on VGA onboard video.
I cannot get the second monitor to detect in any configuration. Tried looking in BIOS of MB, using 2nd DVI (w/ vga adapter) on Radeon card.

Am at a loss and I hope I have provided enough information for some assistance.

Much appreciated

I don't understand why you are using a combination of DVI (to VGA) out of your HD6670 to one monitor, and also using the VGA out of your motherboard to the other monitor.

Am I interpreting what you've done correctly? You are using just the DVI output from your HD6670 through a DVI-to-VGA adapter and on to your first monitor, and also using the VGA output from the onboard graphics of the motherboard to feed the second monitor? If so, this is very wrong.

Your new HD6670 has TWO video outputs of its own: one is DVI, and the other is VGA. You should connect your second analog monitor to the VGA output of the HD6670, not to the onboard graphics VGA output.

Also, if you can disable the onboard graphics in the BIOS that's definitely what you should do when you install an external video card as you've done. At the very least you should give priority to the new PCIe video over PCI (which was your old GeForce card, and probably o... Read more

Whenever my computer recovers from sleep mode, or when the screensaver comes on and I wake it up, I find that all my apps are now on my main monitor.

Example: Google Chrome and Skype on Monitor 1.
Microsoft Word and MSI Afterburner on Monitor 2.

-computer sleeps/ screen saver turns on-
-I wake the computer up-

Google Chrome, Skype, Microsoft Word, and MSI Afterburner are on Monitor 1.
Nothing on Monitor 2.

Is it possible to fix this?

Specs
OS: Windows 7 Home Premium
Using DisplayFusion Pro v5.0.1 to extend my taskbar to the second monitor.

GPU: r9 290
CPU: i5 4670k @ 4.2 Ghz
Mobo: ASUS z87 sabertooth TUF series
PSU: Corsair TX-CMPSU 650W

Answer:After dual monitor sleep recovery, all apps shift to one monitor

I've had dual monitors for years now and have never had this problem. But I also have no screen saver.

If you put your system to sleep why would you want a screen saver? All that does is keep the system active and running - which is the opposite of what sleep does.

Remove the scree saver and see what happens.

About 6 months ago i invested in a second video card to use with an old monitor and a new PC. After much trial and error i eventually got it all working.

A couple of days ago i re-installed windows however and therefore all my settings have been reset and am now havein problems, and if i remember rightly the same ones as before. But for the life of me i cant figure out how to solve them this time round. So any help would be appreciated.

Spec -

2x plug and play monitor (almost sure it has nothing to do with these so wont add details)

1x Nvidia Geforce FX 5200 (AGP) with fully updated drivers (from manufacturers website) (the monitor off this video card works fine)

1x ATI Radeon 7000 (PCI) fully updated drivers (without catylist command centre however due to some installation problems. I had these before when both monitors worked fine..just the drivers) - Problematic monitor

Bios - Dell Computer Corporation A12 (newly updated) (I heard somewhere that this may have an effect).

The Problem-
On my second monitor (Radeon 7000 (PCI) whenever i try to move a frame, scroll in IE etc the refresh rate is appaling. Entire lines get moved at a time.
The only time the refersh rate does not slow is when moving the mouse and scrolling through files in c drive as far as i can tell. If i switch my primary monitor to this one and stop the monitor 'extension' it still flickers. Ive checked my monitors by changing which card they use and as expected, th... Read more

Answer:Dual monitor problems- second monitor refresh times dreadful

Well, could be bad drivers... nvidia and ATI hate eachother, so I dunno why you got cards like that, could be a driver conflict from un-updated windows files, that is to say, uninstall drivers, update everything on windows, re-install newest drivers.

Hello I basically need conformation that I'll need to buy a new monitor in order to have a dual monitor set up with my current system. I'm not super tech savvy so if you need any other info please let me know.

I have a Radeon HD 6670 with 3 ports, an HMID, VGA (which is my monitors type) and DVI. Each port has a stamp next to it that indicates what port type it is/supports (the VGA has a CRI stamp next to it though). My main VGA monitor works fine with the VGA/CRI port, but my second I have to use a VGA to DVI adapter and it's not working.

I've gone through a lot of forums, and found some conflicting information. So I really want to know is it possible to use a converter/adapter or will I need to just go out and buy a new monitor that has a DVI hook up?

I hope I don't need a new monitor, I'm on a very tight budget. (la sigh)

Answer:Radeon HD 6670 Dual Monitor setup not detecting 2nd monitor

I would try one of these before giving up on the monitor:

Rosewill 10ft. DVI-A (24+5) Male to HD15 VGA Male Analog Video Cable w/ Ferrites Cores, Model RCW-900 - Newegg.com

Forget adapters, you might not a have a compatible one, the DVI connector has many variants.

Look at that cable end and make sure it would fit on your video card's female DVI connector (it should), it's DVI-A (analog only) to VGA which is analog only....

Here is my problem. I have a primary monitor and then I run S-Video out to the TV so I can watch video clips.

With Vista, I had no trouble starting a video clip in media player on the primary screen and then dragging it over to the second monitor (TV) for actual viewing.
However, I tried to do that with Windows 7-it won't let me drag Media Player over to the second monitor. I can drag other applications to the second Window (Word, Browsers), but not any media program. Even tried another media player application.

Not sure what to do-how can I get this to work? I want to be able to watch TV/Movies on my second monitor.

Jim

Answer:Dual Monitor Issue-Can't drag MedPlay to Second Monitor

Actually update. I have a hard time dragging anything to my second display. I never had trouble dragging things to my second monitor before. When I get to the right edge of my main display, the window dragging stops..I can't get it to the second monitor. What am I doing wrong?
