Dual monitor issue, secondary monitor is undetectable

Question: Dual monitor issue, secondary monitor is undetectable

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.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

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.

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 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...

Answer:Dual Monitor issue after Sleep, Secondary Screen Apps move to Primary

Have you tried disabling the laptop monitor entirely? Also, try setting your icons up as you prefer, then doing a full reboot.

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 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 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

more information... It's the 'advanced minidock' with keys. The monitor is connected via the DVI port, not the plain old VGA port.

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)
Display Adapter: NVIDIA GeForce GTX 780 Ti
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.

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.

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?

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've been trying to use the laptop screen as secondary monitor in a dual-screen setup but I can not change it in the display properties. The option of selecting an external monitor as primary screen is grayed out. Only option is to use the external monitor as secondary screen or clone, but that's not what I want.
Things I have tried:
*Laptop in docking station
*Update videocard drivers
*Use UltraMon

Any thoughts on this?

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 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'm running Gears of War on my Pc. I have a 19" vga monitor in with the computer and a 32 lcd in the living room. I use the TV as a secondary monitor cloned with the 19" and have the computer connected up to it with a long vga cable.

Now usually when I play games it's fine, but with Gears of War the TV display is all screwed up. The bottom half of the game is on the top and the top half is on the bottom. It's as if the whole display is pushed down and the bottom half is appearing at the top... it's hard to describe but maybe someone has come across this before.

I've no idea what res the game runs at as there are no options to change it...there doesn't appear to be a configuration option. There is an image displayed on the Tv, (almost) perfectly in fact. I can see everything in the game. The only problem is it's cut in half, with the top half at the bottom and vice versa.

I have the latest drivers too...

Also, the monitor displays it fine. It's only this game too. I can watch movies etc on the TV with no problems at all.

The specs are as follows:
x1950pro
Catalyst® Version 07.12
lg lcd tv (max res 1366x768 vga)
windows xp sp3

Thanks in advance,
Karl.

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.

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.

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?

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.

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 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.

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

My display list is backwards

I've tired to fix it but cant. I have the monitors plugged into the correct DVI slots on my video card.

Answer:Dual monitor issue

That number shouldn't matter as long as the one you want (left or right) is set as primary. If it is that you want 1 on the left and 2 on the right, then it is just a matter of dragging #1 to the left side of #2.

I am a computer technician for a fortune 15 company. I have a 62 inch DLP television I decided I would like to use as a monitor to view videos on, rather than streaming it through a server to my ps3 or xbox 360. I have an Nvidia Geforce 7800 GT 256mb graphics card PCI-e. I thought that my television had PC-IN ports so I could use a VGA cable and have no issues, but it turns out I only have S-Vid in so that is what I am using. I know S-vid has a MAX resolution of 480i on my TV and a max of 1024x768 on my vid card. Now, the 480i is fine on my TV, its just that I need my computer to output a higher resolution on my video card to my television, preferably 1280x1024. just so that the text is sharper on my 62 inch. I was thinking there may be a hacked driver for my card to use on guru3d but was unsuccessfull in looking. Would there be any way to get a higher resolution on my 62 inch television without having to purchase component HD cables?

I have a user which uses a T60 running Windows 7 x64. She has a large monitor, which should be her primary display and also uses her laptop monitor as the secondary display. Whenever she locks her station or remove the laptop from the docking station and puts it back on it, she has to redo to reset her monitor to be the primary display. The extended desktop configuration mode still automatically kicks in, just not which screen is primary/secondary. There are no formally compatible drivers for Windows 7 from Lenovo at this time, so I'm using the Vista driver version "8.383.1.1-070621a-049739C-Lenovo". I tried to set up a profile on the Catalyst Control Center, but it still forgets the primary display. I have no idea what to do to fix this. Did Microsoft release a patch for this, or did Lenovo release a quickfix or a driver I'm not aware of?

Question: Dual Monitor Issue

I've just installed Vista Beta 2, and I'm having trouble with a dual monitor setup. I'm using an nVidia GeForce FX 5500 graphics card (128 MB of memory, 2 VGAs out, and one S-Video out).

My goal is to connect two monitors like this: my main VGA monitor running at a very high resolution, and a TV at a lower resolution, connected via S-Video. I've successfully gotten the desktop to span the two monitors like this, but every time I reboot, both screens show the same desktop, both at 600 x 800. I need to manually change the resolution and desktop settings each time I reboot.

Is there some way to get my dual screen settings to "stick" from session to session? Any help would be appreciated.

Question: Dual Monitor Issue

I am running two CRTs on a 6800. I seem to have some problems while running some games that when I move the mouse too far one direction it will force the mouse to show up on the other monitor, instead of being lock in the full screen game. This wouldn't be a problem, except for the fact that if I click while the cursor shows up on the secondary monitor, I will get taken out of the game, and back to my desktop.

I am running Ultramon, and the Nvidia software. This does not happen all the time, only sometimes when I have other apps running in the back ground (CDC from TWL for example).

Any suggestions on how to attack this problem?

When i installed Win8 on my Compaq Presario, Windows update offered a new Nvidia video driver to install.

Did you go into Control Panel - Display - Screen Resolution, then click on 'detect'?

Mind you, i'm using a USB adapter to connect a 2nd monitor since my video card only has the one output. Even then, when i connected via USB, Windows automatically installed the driver.

Question: dual monitor issue

I am running a Lenovo X60 thinkpad with XP Pro, along with an external Viewsonic monitor connected through my docking station. I used to use the Viewsonic as the primary monitor, and the laptop monitor as secondary. Then a few weeks ago when I re-docked my computer the external monitor wouldn't come on. When I go into display properties & try to make it my primary (or my only monitor), it just comes up with a no signal message & goes black. I can activate it as my secondary monitor, but not my only or primary. Also, if my eyes are right, the resolution on the viewsonic seems worse than before.

Any ideas as to what the problem could be?

Question: Dual Monitor Issue

I've just bought a shiny new monitor, and there seems to be a problem.

2 PC's on a desktop; both attached thru a KVM to a monitor.

I added a second monitor to ONE computer, running its cable only to its dedicated monitor, and set up the desktop in Windows Vista so that the new monitor is the 1st monitor, and the older one is the secondary.

The secondary still runs thru the KVM, allowing me to always see the main PC, are you with me so far?

Here's the problem; the second dissplay appears really dim, dark now. Even when I switch the KVM, so that the new monitor is being fed by PC 1 and the "old" monitor is being run by PC 2, the "old" monitor looks positively dim.

I could SWEAR to you that I loved this "old" monitor, and it had no problems. I'm working in a confined space, and don't want to disconnect and reconnect all the cables for the purposes for testing, so I was wondering if YOU could answer one or more of these questions:

1) Could my shiny new LCD monitor really be that much brighter than my 3 year old CRT?

-or-

2) Could the KVM be bleeding off enough signal to be making the display appear dim?

Any thoughts?

Thank you!

I've got an issue, I'm trying to set up dual monitors at work for several desktop work stations and I'm having some resolution issues on the second monitor. It will not let me increases the resolution to the monitors native resolution when I do the screen goes black or is very unstable. The work stations are HP Compaq 6005 pro microtowers running windows 7 professional with an integrated ATI Radeon hd 4200 gpu. The first monitor is connected using the VGA port and the second is connected through the displayport to VGA adaptor, I have the latest drivers installed. Anyone have any suggestions?

Answer:Dual monitor issue

Okay, it sounds like your ATI doesn't know about the other monitor, and since that setting can be OFF though connected, there's a need to turn it ON.  I have ATI on my XP machine with two monitors and an HP 6400; my main Win7 also has two monitors, but Intel HD, and yes displayport to VGA adaptor.  For the XP, there's a tabbed dialog box for ATI;  in Win7, it might be part of Personalize Display Settings, which should reveal if Windows 'knows' you have two monitors connected.  Make sure both monitors are ON, and see.
 
Did you run Windows 7 Media Center?  That helped me.
 
Or, right-click on Win7 desktop, then you should find something worded similar to 'Graphics Options' then a flyout menu gives you 'Output to' and you select 'Extended Desktop': make sure it shows two monitors. But to get the actual settings right, instead of 'Graphics Options' you might see something like 'Graphics Properties', click that and then look for 'Multiple Displays' in the dialogue box.  Click on that, and then re-arrange Monitor 1 and 2 as you actually have them placed, plus change the resolution settings (if needed) for each monitor, including RGB etc. as desired.  Then click 'OK', and the screens refresh;  if you like the setting, 'Accept' it.  The foregoing are the menu options for Intel, but they should be similar with ATI; though perhaps you get a tabbed dialog box instead.  (ATI is wonderful, btw, but I don't have it on Win7. ...

Question: Dual Monitor Issue

Hello,
I'm having an issue using two monitors on my PC.

A bit of background info:
Ive been using dual monitors for about a year by plugging one into my on-board GPU (VGA-VGA) and one into my external GPU (VGA-VGA-DVI-I using an adapter).
For reasons which I can't be bothered to explain because it's not important, my on-board GPU no longer works and I must use my two DVI-I ports on my GPU.

Now, here's the problem:
Both screens are identical, with VGA-VGA wires. I am using an official ATI VGA-DVI-I adapter that came with my GPU (NVIDIA GeForce 9600GT) to connect the one screen.
However, I purchased a cheap ?1.50 VGA-DVI-I adapter off eBay for the second screen. But my problem is that when I connect either screen with the eBay adapter, it doesn't work properly.

Here's a bit of elaboration:
I can connect EITHER screen in EITHER of my GPU ports using the official ATI adapter, and they work fine.
However, when I connect EITHER screen in EITHER of my GPU ports using the eBay-bought adapter, it either doesn't detect any screen, or it caps me at 1024x786 resolution.
When I go to change my resolution, it calls the not-working one "Generic non-pnp" where-as my working one is called Packard Bell 200Ws.

This leads me to believe that there is an issue with my eBay bought adapter, I just wanted someone to clarify that this is the issue?

I don't want to pay the prices that places like PC World charge for a good adapter, so I want to check h... Read more

Answer:Dual Monitor Issue

I'm no expert but it sounds to me like the e-bay bought adapter is missing a few wires that would be used to ID the monitor. If you download the manual for your video card from the manufacturers web site you should be able to figure out what max resolutions are supported. I think its the adapter not a screen resolution problem.

Question: Dual Monitor Issue

Hey, I recently bought a 2nd monitor for my computer. At first everything ran just fine. I restarted my computer and when it came back on, my 2nd monitor got set to my main display, and my original monitor could no longer be set to its "recommended" resolution.

After reading around the internet, I couldn't find any good answers to this problem. I decided to just let the updates go on windows (normally i just don't bother with them) and after I installed them, everything was fine. No settings were randomly changing, the original monitor was set at its recommended resolution ect.

Today I was working on my friends computer so I had mine unplugged and when I went to start mine up after replugging everything back in, the original problem started again. My new 2nd monitor was set to my main display, and my main monitor wont go past the resolution 1600x900 (recommended is 1680x1050). I tried to figure this out but at last I give up and ask for any help I can get to fix this.

Just a side note, my 2nd monitor is a smaller one and sits at 20" so thats why I prefer it to be secondary monitor. Also if I set my smaller one to main display, the bigger one (I think its 23" but its been awhile since I've bought it so I cant remember the exact size) still is messed up.

The main issue is the resolution on my primary monitor not being able to be set to the right setting to look good, right now it is all pixelated.

At home, I run dual monitors. So when I am there, there are programs that open in the right screen. Before I left the area (and intended on bringing just one monitor) I used my setting to change the setup back to using 1 monitor.

However, while Trillian seemed to recognize this change and moved over to the left screen, Vent did not - it opens off to the right (where it can not be seen as I am now only using one monitor). So the question is, how do I get Vent to open on the single (left) screen I have now that I am away from home (and dont have access to another monitor to plug in to simply move it back).

I have a computer that i need to run dual monitors, on my home PC i am using 1 graphic card that has 2inputs so have not had a problem.

However with this setup the graphics card only has 1 output (DVI) so i will also need to use the on board graphics card as well. Tested on each, and they both work individually but not when both connected.

I suspect that when the graphics card is plugged in it disables the on board graphics card, so my question is, is it possible to run dual monitors using both the on board graphics card & the extra graphics card?

*Have looked in device manager, nothing is disabled.
*Plugged them in individually (Worked single display).
*Tried every option in NVIDIA control panel.

The machine is operating WindowsXP & using a Nvidia graphics card.

Question: Dual Monitor issue

I am not too familiar with Windows, but have to work on a project using a Sony Vios running XP.
I need a 2nd monitor and installed an ATI Radeon 9200 PCI video card along with the factory video card.

I confirmed each card works and can drive either monitor independently. But can't get them to work at the same time.

In the "Display" control panel settings both video cards show up and two monitors are there in the screen arrangement window, but which ever monitor is plugged into the stock video port will not work and is grayed out on the arrangement window. The cursor does not go off the edge of the primary monitor either.

I click the box to enable the second monitor to extend the desktop and when I hit "apply", nothing happens.
It asks if I want to have the changes take place right away or after re-start, but neither work.
After restart or any type of setting change, the second monitor goes gray again and the box to extend the desktop is unchecked. It never seems to apply the new settings.

I tried every combination of video card, monitor, primary and secondary settings, but only the new PCI card will work when installed. Remove it and the stock card works again.

I must have the correct drivers since each card will work one at a time. Am I missing a step to adding a second video card?

Thanks.
 

Answer:Dual Monitor issue

"If your PC’s graphics capabilities are built into your computer’s motherboard, they will often be disabled when you add a graphics card. You may need to disable it via the system BIOS (Basic Input/Output System)

Does this mean I cannot use my built in video card?

Question: Dual Monitor Issue

Due to a lost password I had to re-load the xp os on a Dell Computer. Now the system no longer recognizes the dual monitors it always had. There is no identy number, each acts as though it were the only display (identical screens and cursors all the time).

Answer:Dual Monitor Issue

In the Display properties, you have to allow the computer to "extend" the screen. I don't remember the exact settings, but I will try to find them for you.

I'm trying to setup my laptop to where I can use my 52" T.V as a 'monitor', mainly for movies. I bought a VGA to S-Video adapter. My on board graphics is the S3 UniChrome PRO IGP. I have a VGA output on my laptop. I've tried hooking it up, but I still get no video. I've tried setting the display settings, to use a separate monitor, and everytime I have tried saving/applying the settings, every time I do that, it goes back to the default setting, so I have to keep reapplying those settings. Any ideas?

Answer:Dual Monitor issue?

Are you trying to use the TV as the main monitor? If so that wont ever happen. The reason being that a Laptop wont save those settings cause it never knows when it will have to use it's LCD as the main monitor again. So by default it will always use the LCD as it main. That way if you ever forgot to turn that display back to the main, it wouldnt work. See what i am trying to say?

Now if you are jsut trying to use it as a secondary display you imght have to get some better drivers if there are any available. I know ATi and nVidia both have these setting in their control panel. I jsut dont know is UniChrome does.

Question: Dual Monitor Issue

Hi,

I have a Lenovo Y900 desktop with dual Samsung Monitors connected via HDMI connections. I have had the PC for about 4 - 5 months and up until yesterday all worked well. I have been away on vacation for 3 weeks and when I returned I booted up the computer only to find the monitors initially started up and then went blank! When I restarted the computer through holding the power button down and restarting the monitors worked fine.

This is now happening every time I start the computer which is strange. The monitors initially start with the PC then go blank until I restart the PC. This one is baffling me and have no idea what the solution is. Anyone have any ideas?

Reinstall the graphics card drivers.

Question: Dual Monitor Issue

Hi, I have a rather specific and yet glaring issue that's recently come up after some modification to my MacBook Pro mid-2010 running Windows 7. I run W7 on a second hard drive that I installed in order to add more storage space to the 128 GB SSD that I use for its speed.
The problem is, I use an external monitor (connected via DVI from the MiniDisplayPort) that works all of the time except when I try to use it as the only monitor. I'm able to run both at once, or just the laptop's screen, but when I close the laptop and try to use only the external monitor, the monitor claims it's not receiving a signal. The CPU fans are still running, and the keyboard lights are on, so I assume the computer is running, there's just no picture going out. Alternatively, when I used the Nvidia settings to switch the external to main monitor, the same thing happened until I unplugged it and it used the laptop screen again.

EXTRA INFO:
This issue only came up recently, after I switched from a 500GB 5400rpm extra HD to a 750GM 7200rpm HD. I tried doing a clean install on the partition that I made for W7 to fix this issue but it didn't work, and neither did a driver uninstall/reinstall.
I also believe a part of the cause may be the attempt I made to install Kubuntu, during the partitioning stage I accidentally did not make the partition for Linux large enough for Kubuntu so the install failed. The next time I turned on the computer, I was forced to run a chdisk on startup and reboot, at whi... Read more

Answer:Dual Monitor Issue

I think it might have something to do with when you shout the lid on the laptop. Once the lid is closed there is no power to that screen and subsequently no power to 2nd monitor because of the lid being closed. There might be a setting to change/play with on the laptop as to what happens when you close the lid of laptop.

Hello,
I upgraded to windows 7 32bit today and I have a dual monitor setup. Before I had XP, and I could play video games on my main screen, and watch movies/tv and/or browse the internet on the other screen with no problems. Today when I switched to 7, I cannot play my video game (World of Warcraft) on my main screen without it freezing while having any movement with my mouse. Meaning, as soon as I move my mouse, the screen freezes and get 0 frames per second. While if i right click drag mouse, i can turn just fine. This never happened on xp.

Question: Dual Monitor Issue

I am having an issue with my computer recognizing a monitor.  I have a Lenovo T400 in a docking station and it isn't even recognizing that the monitor is attached.  I just recently installed Windows Vista but it had been working perfectly on a previous version of XP.  Any ideas?

Answer:Dual Monitor Issue

If you have switchable graphics (and turned it on in bios when you installed Vista), did you check in power manager switchable graphics menu (right or left click on the larger of the two battery icons) that high performance mode is set? DVI is not supported in switchable graphics energy savings (=integrated) mode. Nor is DVI supported in bios integrated mode but you would probably already know that from XP.

Question: Dual Monitor Issue

I am trying to do a Dual Monitor multimedia show. I have two video cards on my computer, and I am trying to hook them both to video projectors, and play a file that is 1600 pixels X 600 pixels. Basically I am strecthing the file in borderless play using BSPlayer over the two monitors. My issue is that when the window stretches across both screens, the video will only appear on the screen that has more of the window on it. If there is 3/4 of the playing window on the left monitor, I can see video there, and a black box the size and shape of the window on the right monitor. Same if reversed. The video will play on either monitor, just not both. WMP has the same issue. Does anyone know of anything that could fix this problem?
 

Answer:Dual Monitor Issue

I have the same problem, I think it has to do with which monitor it starts playing on, maybe something to do with the way the drivers for the video card run. Since only one monitor can be primary.

You might look into Ultramon and see if it can help you out. I need to check and see if there is a new version.

Question: Dual Monitor Issue

Hey guys,

I recently bought a new Dell IPS Monitor and I have decided to try and run a dual monitor setup with my old one. My old monitor is running at only 1280x960, my new monitor is 1920x1080. The problem is when I extend them together, my old monitor becomes the primary monitor and my new monitor has only a small area of desktop available(I.E. it has a black boxes around a small desktop). I'm guessing that it used the old monitors res for the new one which is larger but I cant seem to find a way to make my old monitor the primary one at full res no matter what I try.

Any replies would be great.

Cheers
James
 

Answer:Dual Monitor Issue

The resolution should be the largest that both monitors support. If they are using less than 1280 x 960 probably the new monitor does not support that particular resolution.

Question: Dual Monitor issue

Ok. Have always run at least dual monitors on all my systems. Had no problem with the Dell Monitor(VGA) I gave my buddy for his lappie.

I have the HDMI port, and wanted to use a 19" TV to play WoW on of course...lol

Hooks up fine, have no trouble spanning the desktop etc. The problem lies in that task bar, and top of the screen are beyond view able range. Tried different modes on the TV, different screen resolutions, etc. Nothing works.

Now here's the rub. If I use the STD HDMI TV I have it works perfect. Looks like my main screen. Have it spanned of course. Moving apps is fine.

WHY would the screen on the 19" do that if everything else I throw on there is perfect?

Hi everybody,

First off, this is my first post around here, so hello, my name's Chris, I live in Ontario and I use a computer.

Anyways, a few weeks about I spent around $2100 building a new computer, and everything has been going smoothly. One of the more expensive components of this new computer was the video card, the EVGA GeForce GTX 570. Up until today, I've had no issues with it. However, today I went out and bought a second monitor, knowing that my video card would be capable of handling it. While the dual monitor function works almost flawlessly, there seems to be some sort of boundary issue. For example, when I move my mouse from the bottom left corner of the right monitor over to the left monitor, the mouse ends up about 3 1/2" from the bottom of the left screen. Similarly, when I move the mouse from the top right of the left monitor to the right monitor, the mouse appears around 3 1/2" from the top of the right screen. When I try to reverse these scenarios (e.g move the mouse from the top left of the right monitor to the left monitor) it stops at the left side of the right monitor as though the left monitor wasn't connected.

So, hoping that you've managed to navigate through my labyrinth of 'right's and 'left's, I was wondering if any of you Windows 7 Professionals might be able to lend me a hand in perfecting my dual monitor setup.
Thanks for reading,
Chris

Laptop: Lenovo Thinkpad T430
Docking station: Thinkpad mini dock series 3

VGA and DVI connecting

I have the same setup at home that I have at work. Just different monitors. Same docking station and transport my laptop from work to home. At work I can plug my laptop into the docking station, close the laptop and my display comes up on my monitors. At home if I close my laptop it shows nothing on either monitor. If I leave it open, it shows on the laptop screen and the monitor that is hooked up by VGA. If I go into Display and Screen Resolution, it is detecting my 3rd monitor, however no matter how many ways I try to extend it, copy it, etc the 3rd monitor still will not show up.

I want to have it like I do at work where I can close my laptop and show up on both monitors.. Please someone help me?? I've switched out the chords to each monitor to see if that helped, but still only able to connect to the VGA screen, could this indicate that it's the DVI that is the issue?

I've even tried using a docking station from work to see if my docking station was the issue and it's the same thing.

Hi I need assistance, I am currently running windows XP on a laptop with a second monitor, everything will connect and both monitors work transferring data between them, the issue is that space on my desk only allows the CRT to be on the left of the laptop. I can change settings and allow transfer from right to left and this works until I turn the computer off and then on again it reverts back to left to right setting. How can I get this to save in my profile permanently so I don't have to change this setting each time I turn the laptop on. note: I have tried with the Nividia settings and in the Windows settings accessed from desk top.

Didnt really know which area to post this in, so i thought this was the most suitable.

Just have a issue regarding dual monitors on a windows 7 machine. I will provide as much information as possible:

I recently purchased a cheap graphics card - nVidia Quadro FX 1500 (2 x DVI) to run a dual monitor setup. My original monitor (Acer x243hq), connected to DVI via a VGA-DVI adapter and a newly purchased Samsung BX2440 (connected direct DVI).

Individually the monitor are each capable of a 1920 x 1080 setting, but as soon i plug in both monitors, the Acer resolution blows up and i am unable to see desktop icons and task bar (when it is set to primary, maximised window will be significantly cut of when set to secondary and have a internet browser open).

When i right click and go into "screen resolution", both screens are showing 1920 x 1080, but it is clearly not the case.

Is there any solution for this? I did a search and cant find anything regarding this.
The only solution i have is that the video card is having trouble running both monitors? The specifications however suggests it is capable of this.....

Any ideas??

Thanks in advance!

Answer:Dual monitor resolution issue?!

Check the NVidia control panel for resolution settings there, set it to the native resolution for each monitor.

Also, get a straight DVI to DVI cable for your monitor, that might have something to with it.

Check your refresh rates for each monitor as well.

Due to network security which can't be changed, the PC locks out after a while not being used. When logging back in, one of the monitors fails to come back to life again, generally a the dell monitor.. Try turning it on/off but power light remains on. It appears totally frozen. Only way to reset is to pull power lead out of monitor, leaving for a few seconds until power light fades to off. Plug back in and it all works again fine, well until it next auto locks. Any ideas?

My problem is I want both monitors to display the complete desktop as if each were primary display. For some reason no matter what I set the resolution to on the Dynex the taskbar and a bit of the desktop all the way around the screen is cut off.

Hello, I have a T500 with the ATI HD 3650 graphics.  I have two monitors: 1.  Lenovo L192 Wide (main monitor)  Plug is VGA2.  IBM L170P  Extended second monitor.  Plug is DVI I also plug my laptop into the advanced docking station and both monitor connections are plugged into the station. When my laptop boots the following happens.  it trys to display on the IBM L170P then the Lenovo L192 then they both go blank then the L192 works and then the L170P works too.  During this time all my icons move to the left side of the screen since it's trying to do something with the resolution settings. Can someone help me fix this?  I keep all my icons in certain places and have to move them around everytime I boot my laptop. Thanks -Nick

Answer:Dual Monitor issue with T500

Nick, Try this:- Go to BIOS setup when you start the computer (press F1 when the Lenovo logo comes up) - Select <Config> press enter- Select <Display> press enter- Set primary device as PCI Express- Set boot display device as either "Analog" or "DVI" - this depends on whether you also use the computer separately.  If you set it this way and you use the laptop away from your other monitors, you won't see it boot. These instructions are based on my older T60P, but should be similar (My T500 is not here with me).  I think if the BIOS is set up to match your monitors, then windows will default to that.    You didn't mention if you use Vista or XP.  I find that Vista handles monitors much better, for what it's worth. One last thought -  you might also try disabling the Thinkpad LCD altogether.  If you set BIOS to boot using the external displays, then go into Windows Device Manager and disable the LCD display, that will force windows to start up with the external monitors, and it should remember the resolution settings and not have to detect them every time. Hope this helps! Don Mannino

I am trying to set up dual monitors and not having any luck. I purchased 2 of the the Dell SE2416H monitors yesterday and I have gone HDMI to tower and VGA to the other computer, then flipped it around and did VGA to tower and hdmi connecting the 2 monitors and nothing seems to work. I've tested both monitors and they both work, just not with each other. I've right clicked on my desktop and went to Display Settings and it does not give me an option to "Extend Display". I've gone to the Intel HD Graphics Control Panel and then Multiple Displays and it only gives me the "Single Display" option. The monitor that is not hooked up to the tower turns on (yes, I have the power cord hooked up), but the screen is black and it says that "No VGA Cable" (even when it has one plugged into the other monitor). My tower is the Dell inspiron 3847. Please advise. TYIA

Answer:SE2416H Dual Monitor Issue

Version of Windows?
How are you connecting these monitors? Both to an add-in video card or one to an add-in card and the other to on-board video?
Assuming you have an add-in video card AND it supports 2 (or more monitors) they both have to be connected to the add-in card. On-board video ports are typically disabled when an add-in video card is installed.  
Video ports on an add-in video card will be in the area inside the green box marked in this diagram. On-board video ports will be in the area marked with the red X, and cannot be used when there's an add-in card.

I am currently using this DisplayPort to DVI adapter: http://www.amazon.com/C2G-Cables-To-54321-DisplayPort/dp/B00J9CLWP2 I have tried updating the driver for the installed Intel HD Graphics 530 display adapter, and I have tried powering off the computer and powering it back on with only the DisplayPort cable plugged in. I have switched cables between the two monitors. I have a feeling it might be the adapter, but I was hoping someone here might have more insight.

Hey all, general question about setting up dual monitors.  I bet its been asked before but my situation is a bit different because the computer is a tad old.The computer in question was just running video from the motherboard, always worked of course.  Its a workstation, so it never really needed anymore then one screen.  With the introduction of new software, the employee who uses the computer has had considerable loss of productivity because the computer couldn't handle the extra software running.  We put in another memory stick and all was well.  However, inefficiencies still ran rampant because the screen was too small for him to handle so many programs.  A solution that management agreed upon was to setup a 2nd monitor to split up his programs in a more organized fashion.I've setup dual monitors before, didn't think it was going to be a big deal.  The motherboard already had its onboard video, so I installed a Nvidia GeForce3 Ti 200 (Yes, this is a very old computer but it runs awesome).  I plugged one monitor into the motherboard and another in the newly installed video card.  Installed the drivers and updated, seemed everything was going well.  After restarting the computer, this is windows XP, I turned on both monitors and it seemed to only be working on the one plugged into the geForce card.  After some investigation there seemed to be no option in the Display Properties to have a dual monitor func...

So I got a new video card, GeForce 210 DDR2 512 mb PCIs 2.0, to allow my computer to have two monitors since it's easier for my designing, but now my sound doesnt' work at all. On my built in AV card my monitor plug and sound plug do not respond at all, like they're not even there. I had to plug both monitors into the same card for it to work. I took my speakers to my mom's computer and determined they still worked and tried hers, which I knew worked on mine, but they still didn't work. When I went into the sound control panel it didn't even recongnize that there was a sound device attached.

Other system specs. HP pavalion a133on with an AMD 64 athalon processor, Windows XP, use IE 8.0.6001.18702IC and Firefox 3.6.3
 

Answer:Dual monitor sound issue

Are there any sound settings in the Nvidia control panel? Are you running the latest video drivers from the Nvidia support website? Do you see any yellow exclamation marks in the Device Manager? If so, you may have what's called a IRQ (Interrupt Request) conflict

I have a question in regards to my dual monitor system. No one seems to be able to get the fix for this. I can tell you that it worked fine forever and then one day it just does not work properly. Using my computer with Extened Display Windows 7 works fine. Computer Goes to Sleep hit the space bar or move the mouse and it wakes up with the same view which is correct. Main Monitor on the Left and Extened Display on the Right. So No Probelm. I switch over to another computer with my IOGEAR KVM Switch which is Dual View work on another computer Dual View. No Problems. Here is where the Issue comes in. When I switch back to the other computer it comes up but the main monitor on the left is now Blank like its powered off and my desktop is now on the monitor on the right. I goto the display options under resolution and hit the detect button. It now moves my desktop from the right monitor to thte left primary monitor and all is well. So for some time this just becomes annoying that I have to do this everytime I want to switch back over. It does not do it on any other computer and I have tried everything. Remember it used to work.
Here is what I have done so far to rule out the hardware. Bios is set up correctly. Replaced Video Card. Latest Driver has been installed etc. I returned my KVM Switch 3 times to be sure it was not that and it is not. Why do I have to keep hitting the Detect button in order to get it back to where it needs to be on this one computer. Please Help. My name i... Read more

Wasn't sure what the appropriate category was for this post. Please feel free to move it if I have entered this into the wrong category.

I have 2 laptops and one separate monitor. I have an IOGEAR KVM to swap between the two with the separate monitor plugged into the KVM. This separate monitor completes a dual display setup for each of the two laptops. When I toggle between the two laptops, the separate monitor is correctly identified as the second monitor in each configuration.

Here is my issue...when I toggle from laptop 1 (Dell XPS with Windows 7) to laptop 2 (IBM Lenovo T400 with XP Pro), laptop 1 recognizes that all of the windows on the second monitor should stay on the second monitor even though the second monitor is now being used for laptop 2. When I toggle back from laptop 2 to laptop 1, laptop 2 no longer recognizes the the second monitor and kicks all of the second monitor windows to the display of laptop 2. Obviously, laptop 2 believes it is a single monitor setup when the KVM is directed to laptop 1...but the curious thing is that I am using UltraMon on both systems to manage the dual display configuration and the options and settings are the same on both.

Why would one system decide it is suddenly a single display setup when the KVM is pointed to the other laptop, but the other one not behave that way?? Is there perhaps an XP specific or Lenovo setting I need to check somewhere??

I recently bought a 24' widescreen monitor which works fine by itself via DVI at 1920x1200. However, when I attach my 20' monitor via the secondary VGA port, all video playback (VLC, Media Player, Power DVD) runs very slow or skips alot of frames (depends on the software). Oddly enough, this occurs even if the second monitor is disabled though the issue goes away if I unplug it.

I am using a X800XT PE to power the monitors and I should add that games (ie Supreme Commander) still run perfectly fine including the in-game videos.

I have updated the drivers to the latest on the ATI website but this did not fix the issue. Does anyone have any ideas?

I've got two monitors, an Acer 22" primary and an LG 21.5" secondary on the left. I used to have it so that the tops of each monitor meet, but since they don't match on the bottom, any desktop icons on the last row would be shifted upward one row on reboot. After finally getting sick of that, I put a book under the main monitor and made it so that the bottoms of each monitor lined up and repositioned it as such in both Windows display properties and UltraMon. That made that issue go away, but now another one appeared where videos playing (streaming online or on HDD) slow down and skip frames until I mouse over them. I haven't tried changing back to match the tops again, but I'd rather not have to. Any suggestions would be great.

I have a brand new M700 running Win 10 Pro. i am running dual monitors - a brand new Asus on the DisplayPort which is working fine. any monitor attached to the VGA woks but has faint colors. i have tried two new monitors and one old with the same results. Monitors work fine on the DP but not on the VGA. Tried new cables BIOS tweak etc. and nothing works. Lenovo Tech was out here and replaced the mother board but the problem still did not go away. 

Answer:M700 Dual Monitor Issue

This appears to be a desktop (ThinkCenter) system and not a ThinkStation.  So this is posted in the wrong forum.
 
That being said, I'd probably ask if you have any dongles/converters/interposers in between the VGA port and the display being driven off that port.  If they've swapped the motherboard on the system, then I would tend to think the issue lies somewhere after the VGA port (i.e. display, cable, or dongles).  Though it does sound like you've checked different displays and cables to attempt to rule that out.  If there's an in-line converter being used that wasn't changed out, that could be the issue.  Just a guess though.
