Cannot use external monitor as the primary monitor with Portege M400

Question: Cannot use external monitor as the primary monitor with Portege M400

I am unable to use the extended deasktop feature with my m400. I installed the latest video drivers. When I go to the intel graphics media accelerator driver under display properties and choose extended desktop I can't use my external monitor as the primary monitor.

Answer: Cannot use external monitor as the primary monitor with Portege M400

Hi

Maybe is it technical limitation of Intel graphic card. I know for example that on Portege M200 it is not possible to set the external monitor as primary device and the internal screen as secondary device. No way.

Maybe some M400 owner post own experience about that.

I have a Portege M400-s5032x tablet and a pa3680u docking station. I would like to get a bigger external monitor for use with the dock, what is the biggest monitor I can use?

I have a 18.5 widescreen on there now and would like to go up to a 20 or 22 inch widescreen.

Answer:What is the largest external monitor that I can use with Portege M400?

As far as I know there is no limitation. You can use whatever you want.
Only thing that can be problematic is screen resolution.

Has docking station DVI port?

Can the Portege M400 SXVGA (i.e. 1400x1050) support 1400x1050 via analogue to external monitor? I ask this because I can't get it to! The largest it is happy delivering, even though the monitor is a TFT 1400x1050 screen, is 1280x1024.

I have downloaded the latest Intel drivers, and screen drivers, and although the O/S is reporting the screen as being happy to show 1400x1024, it is not an option when selecting resolutions.

Is this a known problem?
Is it rectified by using digital?
Am I being stupid?!

Answer:Portege M400: Is it possible to use 1400x1050 resolution on external monitor?

I would like to be able to use the laptop screen as a tablet whilst viewing an external monitor. The problem is that when using the laptop in its tablet configuration (the screen rotated and clipped in on top) the external monitor shows the image upside down. If I rotate the output for the screen image then I have to use the tablet upside down which is impossible when docked. Is there anyway of independently setting the screen rotation for the tablet and that of the external monitor?
If anyone could help me with this I would be grateful as at the moment I have to undock the tablet and use upside down or not use the external monitor.

I am using Windows tablet SP on a Portege M400 and an external 22" LCD monitor

Thanks.

Hi All,

I have a 24" Wide screen monitor connected via the docking station on my M400. My question is, is it possible to also use the internal LCD and it's tablet functionality when using my 24" monitor.

The 24" display is fine but the internal LCD display is rotated 90 degrees giving a black border top and bottom (portrait way up) but the digitizer is working in landscape mode. So if I move the pen down it moves to the right on the screen :)

It is so close to being right I hope that this can be achieved. It would be great to work off of the 24" monitor and to have the Windows Journal open for writing notes on the tablet screen.

Thanks,
Royce

Answer:Portege M400 - Vista - External Monitor + internal tablet functionality

Hi

Hmmm? if you want to change the screen orientation I would suggest to checking the Toshiba Tablet options.
There you should find the Tool called ?Rotation Utility?.

This Utility provides some option to change the screen orientation in the PC mode and in the Tablet mode.
When the notebook was set to Tablet mode you can choose between Primary portrait, primary landscape, secondary landscape and secondary portrait.

Check it simply

Hi,

I am using my Toshiba M400 in the port replicator.
The port replicator has two display outputs, one DVI and one external analog output.

I would like to use both monitors at the same time under Windows Vista RC1.
The port replicator manual mentions this should be possible depending on the computer connected to it.

"Depending on the computer connected to the port replicator, you may be able to connect external monitors to the DVI port and the external monitor port and display screens on both monitors at teh same time."

Does someone knows it the M400 supports that? I only get the DVI OR external monitor to work.
(It used to work with my old other and that function was just great).

Thanks a lot in advanced.

Answer:Portege M400: Port replicator using DVI Monitor and analog monitor

Hi

I am not 100% sure but pretty sure that you can not connect two external displays at the same time because of notebook graphic card restriction. You can extend you?re your desktop to two displays (internal and external one) or have the same picture on notebook LCD and external TFT connected to DVI or RGB port.

If I read carefully the sentence you posted I have understood that you can use both ports (depending on notebook) and use both displays screens on the same time (notebook display and external one).

All available modes to switch display to external one you can check with FN+F5 key combination or in ?Display Change Service? tab in Toshiba mobile extension tool.

When my laptop is plugged into an external monitor, the laptop screen is the "primary" display, where programs automatically open, etc. Is there a way to make the primary display not the laptop screen but the external monitor screen? Here's the catch--is there a way to do it *without looking at the primary monitor*?

I have this strange request because my laptop's screen recently died. I have connected an external monitor, and so can still use the computer--more or less. The problem is that I can't see my start menu, etc--they are all on the laptop screen, ie, the dead one.

I know, normally, how to switch the display: I would right click on the desktop and select "personalize," then "display" But when I do this, it opens the display in the primary monitor (the broken laptop monitor) and I can't see it to change the settings. It's a sad catch 22.

If anyone could help me with this is would REALLY appreciate it. Thank you.

I need to use an external monitor as my primary and I have Windows XP installed on my 3000 N100. How do I do it?Thanks in advance,Lynn 

Answer:Can I use an external monitor as my primary monitor in Windows XP

   Yes. This should be an option under the software driving your graphics adapter.   There is more than one way to access that.  Shut your laptop off, connect your external display to it, start the display & then the laptop..  The laptop may well show you a dialogue asking how you wish to use the external monitor, just follow the dialogue to use an external monitor as a primary one.  If not, open Control Panel, then open 'Display', go to the 'Settings' tab, where your choices will be displayed.   Some monitors have downloadable drivers that provide more options that your basic operating system provides.

Hello,

WE've juste purchased 2 Protege M400 and 20" Wide (1680x1050) monitors to go with it. Thr problem is that the current driver provided by Toshiba doesn't seem to have this resolution. The graphic hardware is perfectly capable of handling though, since it goes up to ~2000x1500 and is compatible with wide screen displays and digital TV.

This is a high end laptop with all the latest technology.
I'm quite sure it's a driver issue, I've tried several from Toshiba and Intel without luck.

Any ideas ?

Answer:M400 cannot output 1680x1050 to external 20" Wide monitor

I agree with you. According the users manuals this resolution is not supported (Appendix B ? Display Controller and Modes). Sorry but if the original Intel driver can not help I don?t see there other solution.

Answer:How do I make external monitor as primary for laptop?

On some laptops, if you have an external screen plugged in, both the LCD screen and the External screen will show the POST, Starting Windows, and then the login screen. Some laptops do not, as the external could be only ran by the Operating system. I used to have an old Acer Aspire 5536 with Windows 7 Home Premium x64, and I would have an external screen plugged in for gaming. My system always booted from the primary, and never showed on the external until Windows was booted.

You can set it as your primary in Windows, but not as primary in the BIOS, unless there is a setting to change that.

I have connected an external 1280x1024 flatpanel to my A2, set extended desktop and the native resolutions, everything looks "sharp".

But every time I click on the "make this (external) monitor the primary monitor" box (and apply...); the external screen goes black and the portable screen goes back to 640x480 resolution...

Before I was perfectly able to make my external screen the primary one, but since the 1.30 --> 1.40 firmware update this doesn't seem to be possible anymore... Still, in my monitor-preferences the appropriate box is clickable. I also updated the graphics-card drivers, but no better results there.

The screen on the R500 (PPR50E-01301TEN) is fine for use for an hour or two on the go, but if I use it persistently through the day, I get a bad neck and headaches (may be the angle that you have to look at it as much as its small size). So I want to get external monitors for it at work and at home. The home one would preferably be an LCD TV.

The trouble is, Windows tells me that the supported widescreen resolutions for the external monitor are 1280x768, 1920x1080 and 1920x1200. Linux only wants to offer me 1280x800 or lower, although I might be able to fix that with a bit of tweaking. Assuming Windows is right, does anyone know of an 18-21" widescreen monitor or TV with one of the supported resolutions as its native resolution, or even as a supported resolution? I can't find anything.

It probably needs to be 1920x1xxx, because 1280x768 is going to be pretty grainy close up on a 18"+ monitor. Why aren't any of the intermediate resolutions common on widescreen monitors (e.g. 1440x900 or 1680x1050) supported? If it can do 1920x1xxx, it should be able to do them.

Hi, Poonti
 
Have you checked your video settings in BIOS? If not, then I would recommend doing so to make sure that this issue is not being caused by a setting. 
 
To enter the BIOS, turn on the machine and tap Enter repeatedly. Do this until a meny appears with a list of options. Press F1 to enter the BIOS. Once in here, navigate to Config ? Display and see what the setting for the Graphics device is. Try setting it to Switchable if not already set at that.
 
Hope it helps,
Adam

Please check it because it could be possible that your external monitor could be affected.

But if it’s not the external monitor issue, I would recommend you to reinstall the graphic card driver as well as to check the monitor functionality using different screen resolutions.

Following up a recent post about using an external monitor with the M400, I have a query about using one with the M200. I realise that the M200 uses the Nvidia graphics adapter rather than the Intel graphics adapter in the M400 - is this better as far as using an external display is concerned? The M200 manual says it will support up to 1600 x 1536 resolution on an external display. I want to use my M200 in a docking station with an external monitor on extended desktop.

What would be the best resolution to go for with the external? Should I go for 1400 x 1050 to match the M200 LCD display? Or could I go for a 1600 x 1200 which the graphics adapter should (!) be able to cope with? Or, finally, if I went for a 1680 x 1050 widescreen, how would the Nvidia adapter cope? Would the display be as clear as with the 1600 x 1050 screen?

What are the chances of it working at all? I see in the M400 manual that it is supposed to support 2048 x 1536 on an external monitor but this seems to be a problem judging from the other post.

Any help appreciated - thanks

Answer:Portege M200 with external monitor - what's the best resolution?

Hi

Well, the screen resolution depends firstly from the graphic card.
If you want to use any display resolution the graphic card must support it. Furthermore the graphic card driver is important. If the graphic card will support the screen resolution BUT the resolution is not listed in the graphic card driver so you will be not able to choose this value.

In my knowledge if you use the docking station you will get supported display resolutions like on the notebook.
The external display resolution depends also on the external monitor. If the monitor hardware will not support the resolution so you will be not able to get any pictures on the external monitor.

I think the best way is to test what resolution is the best. Some people prefers the high resolution with small icons and other ?blind man? ;) loves the low resolutions (1024x768) because of the big icons

Hi I'm using Window Vista Home Edition. I've been using an external CRT monitor with my laptop for several months without problems. To connect to the external monitor, all I do is tick the 'extend to this monitor' button then 'apply'. I can then move windows to the external monitor and watch movies.

However, since yesterday my laptop does not display images. I put on the external monitor and noticed that my desktop, icons, etc were all on the external monitor. Even worse I when I go to the display settings, I see that the external monitor is labelled 'default monitor'. On the Nvidia control panel it is shown as 'primary monitor' and has the number 1. When I try to set my laptop as primary on the Nvidia control panel it brings up a dialogue box to stop me from changing it.

To my surprise, I now have to tick the 'extend to this monitor' button to view images on my laptop, which is a blank desktop with blurred image and colour. Also I have to move the mouse to the left of the CRT monitor to get to my laptop screen, the complete reverse. When I click on 'identify monitors' it shows my CRT as 1 and my laptop as 2!

This is crazy! I need my laptop to remain as the default monitor, number 1, and primary. But it now seems the CRT has taken over as my main display.

When I power off, disconnect the CRT, and power on, the display returns to my laptop. But as soon as I connect the CRT to my laptop, my laptop display goes blank and the CRT takes over.

Hello All,

I have an M200 tablet with GeForce FX Go 5200. I have a Toshiba docking station and an external LCD display.

Unfortunately I cannot find the right combination of settings for this. If I set Windows to extend the desktop to the external screen, the "use this as the primary display" option is greyed out.

Alternatively, I would like to run 1280x1024 on both the built-in-monitor and the external monitor and then turn off the built-in-monitor, but this does not seem possible either; the resolution changes back to 1024x768 when I try to toggle the desktop onto the external monitor.

I have updated the display-driver.

I hope somebody can help.

Answer:Toshiba R100: External monitor as primary display device

Hi,

as far as I know the Portege R100 has only 1024*768 as higest resolution. So it is impossible to set the both monitors to 1280*1024. Sorry!

Did you tried to FN + F5 keys to change the display output?

Hi folks,

I just installed a Portege M400 with an external monitor from other manufacture. This monitor optimal resolution is 1680x1050. I installed the latest available Intel drivers from the toshiba web site together with the monitor drivers from display manufacture. I can't get this combination in its optimal resolution. Can someone of you help me with this issue please ?

One thing you should know : the monitor works perfect on an other portable... so it has nothing to do with the monitor itself...

Thanks in advance...

Answer:Portege M400: Resolution 1680x1050 on external display not available ?

Hi Steve

I think you are not able to use this resolution because it?s not available in the graphic card properties.
In my knowledge the graphic card driver doesn?t support different resolutions. Some of the resolutions are disabled or not listed in the graphic card driver.

Some users have solved such issue by using a different graphic driver but this was only possible on units with the nVidia or ATI graphic cards.
Unfortunately, I think there is nothing to do.

I bought Dell 24inch wide LCD monitor.

I thought my portege R100 can support 1920x1200 resolution because it's maximum resolution is 2048x1536, but it doesn't. TT

Graphic chip is trident cyber xp4.

I already tried using PowerStrip software but it didn't work for trident graphic chipset.

Is there any way I can use WUXGA(1920x1200) resolution using my portege R100 like regestry modification or what ever?

Answer:Portege R100 and WUXGA(1920x1200) external LCD monitor

Hello

I have found info that 1600x1200 is max supported resolution for Portege R100. As far as I know there is no way to change it through any registry modification. Like you know the graphic card performance can not be changed.

Hi!

I got some problems with my new external Samsung TFT. I hope somebody got an idea.

Is it possible to get a display resolution of 1920x1080 with the R200?

On its data sheet its written something about an external resolution 2.048 x 1.536 ...

But when i connect the tft, press fn+f5 to switch to external tft im just able to set 1280x1024.

I installed the Samsung SyncMaster driver and the problem is already there. No higher resolution then 1280x1024 at 60 Hz for my

new TFT even if i try to expansion the desktop on the other screen. ??

Answer:Portege R200: Can I get 1920x1080 resolution on external monitor?

Hi

Possibly you will not be able to use your favorite resolution on external monitor.
There are two reasons why such resolution is not available;

1) the graphic card chip does not support such external resolution
2) the graphic card driver would not support this resolution.

If the graphic card chip does not support such external resolution then an driver update will not help you?

But if the graphic card would support such resolution but the resolution would still not be available then the graphic card driver should be updated.

Anyway, first of all you have to check if the graphic card would support this. For that you have to check the user manual? I think at the end of user manual you can find all available resolution.

Hi support!

I own a Portege R600 13Z and a ASUS VW224 VGA monitor. Native Resolution is 1680x1050 and connection directly over VGA cable (don't know whether there's a docking station). GPU driver date is 31.03.2010 version 8.15.10.2104 (the newest I believe).

The problem is that the monitor is flickering. The darker the displayed area the stronger the flickering is perceived. It is a "horizontal flickering", as if horizontal lines are chasing each other up and down the screen. It's very annoying.

Since neither the notebook monitor itself nor the ASUS Monitor with another computer show any flickers I believe the problem is rooted in the interaction of the described setup. On the monitor itself I can set different settings. Linked to the problem might be Clock 50 and Phase 54.

Windows tells me in the monitor config that refresh rate is 60. However, Clock and refresh rate can be set to the same without any change.

The meaning of phase I don't know.
Any ideas to solve the issue?

Cheers!

I think it?s grounding issue.
Please check if the flickering would be available using only battery power.

I read a lot about such symptoms on external monitors.
In most cases the usage of 3 cord power cable would solve this problem.

I have a M800 connected to a Dynadock U docking station.
I have problems when i try and set my external monitor as the primary device and have have the laptop as the extended monitor.

I am running Windows XP.

The only options it will allow are: Clone, Extended (laptop is main and external is the extended option)

If i use the WIndows Graphic option it will not allow me to set the external monitor as the main display (i tick this option and click apply and it remains unticked)

If anyone could help that would be great.
Otherwise i would recommend not to use the dynadock

Answer:Portege M800 and external monitor with Dynadock issue

Sorry mate but I still don?t understand what you are speaking about? What problem do you have?

Fact is that Dynadock video drivers give you the option of viewing a total of three screens.
- The screen on the notebook,
- external monitor connected to the video port on the notebook (if available)
- ewxternal monitor connected to the Dynadock

Furthermore you can use Mirror Mode and Extended Mode.

Mirror Mode creates an identical display ? from your computer screen to the external monitor
Extended Mode extended Mode lets you split your display across multiple monitors.

These are the features which you can use in connection with Dynadock

I am using an LG Flatron L1811S external monitor on my Portege M800 and find the image is not as rock solid as when I use the display on my desktop or the M800's own screen.
It's most noticeable on big patches of block colour where I can see slight shimmering. I have noticed this is especially bad if I have recently reconnected the laptop to the mains after using on battery until the battery is fully charged.

This makes me think the PSU is interfering with the VGA output?
Any ideas?

Hi

In my opinion this is not possible.
In extended mode, you are using and internal display but extended and the extended part is visible on the external monitor.
In such case its no matter that your external monitor is set as primary display.

If you want to use external monitor only, you can output the video signal to external monitor only be pressing FN + F5

The external monitor is with the main colour purple.

The labtop detects the monitor right and all works well, but there is since today a main colour purple over all.

Its the same wth a beamer!

Answer:Portege R700 - External monitor color is purple

How about the internal display?
Does the purple color appear on internal monitor too?

In case the internal monitor is OK, the graphic chip should be also OK and in such case I think the video out port (RGB / HDMI) or the cable connecting both devices could be affected.

In case the purple color would appear on internal display too, then the GPU (graphic chip) could malfunctions.

PS: what notebook model do you have excatly and how did you connect the external monitor/beamer to the notebook?

Hi - I have just got a new Portege; R600-102. It is an excellent machine - very light and fast.

I connect to a Slim Port Replicator at the office and I would like to be able to dock and automatically use the external monitor without opening the laptop. Can anyone point me in the right direction on how to do this? This process worked fine on my recently retired Dell X300.

Specifically:
# I have the Portégé laptop closed and in standby mode
# I dock it into the Slim Port Replicator (SPR)
# I press the 'on' button on the SPR
# I see the "resuming windows" message and the countdown bars on the external monitor. (So I know it is connected and can see the external monitor)
# The laptop powers up but uses the (closed) laptop LCD screen
# I have to open it up and tell it to manually "output to monitor".
Can that be done automatically?

Thanks for any guidance.

I'm trying to get an external LCD TV with native resolution 1360x768 connected to the external VGA port of my Toshiba Portege M400. This only works with an external resolution of 1024x768. Wide screen resolutions are just not available in the graphics options. I tried this also using Powerstrip, but I did not manage to get it to 1360x768. With another laptop I did.

According to the specifications of the Intel 945GM chipset, it should support wide screen resolutions. It seems to be just a shortcoming of the Toshiba drivers. Is there any solution to this problem?
Marijn

Answer:Portege M400: no wide screen external resolution (1360x768)

Hi Marijn

I saw the other posting where you have posted about the same theme and unfortunately; there is nothing to do!
It seems that the driver doesn?t support this resolution. Not every screen resolution is listed in the graphic drivers.
If the graphic driver doesn?t support your favorite resolution so you have no much possibilities. You have to choose and to use a available screen resolution.

Hi guys,

just had a question regarding my Toshiba Portege R700 as the screen went blank and i couldnt see the display or sometimes i could and it was very dark!

however the laptop would boot up as nomal and i could use it normally through an external display!

i subsequently replaced the screen and it started working again (happy days!)
However a few weeks down the line the same problem again the screen apparantly dies.

So i take it apart again and disconnect and reconnect the screen just to see if it would solve the problem and it did, its back and working again. I even tried the old screen i swapped out and that works too!
So i paid ?140+ for a new screen i didn't need, my question is what is the problem?

Cant find anything else on this topic so would appreciate any help thanks

It difficult to say what could be wrong here? usually dark screen can be related to an faulty FL inverter.
But the notebook?s display supports an Led backlight so FL inverter should not be a problem here?

At my work we have a number of Toshiba Portege R500 series laptops. All the laptops are docking into a Toshiba Slim Port Replicator II. The laptops are all running a build of Windows XP Professional with Service Pack 2 applied (and obviously some business customisation).

The problem is with the display on the External monitor. The laptop boots up as per normal and logs in fine. The Fn + F5 buttons are pressed and as a result we can switch between the external LCD monitor and the laptop monitor. We can also extend the desktop to the external monitor without a problem.

The problem is that when undocking the laptop from the Replicator, when the laptop is redocked, the external monitor display does not display anything. The monitor is receiving a signal as we do not get any errors about "cable disconnected" etc. By cycling through Fn+F5, the monitor will go to sleep (as the setting is only to be on the laptop screen). Pressing Fn+F5 again, the monitor looks to wake up but there is no display on the external monitor.

The only resolution we have found for this so far is to shutdown & restart the laptop and the external display works again. However undock, and the problem re-occurs.

Thought this might be a driver issue or a Toshiba utilities issue, so have updated the drivers accordingly. The drivers installed by default are the Intel 945 Express driver version 6.14.10.4837. I have attempted to update the drivers to the next version up (using ... Read more

I have an Portege R500 running Vista with a Slim Port Replicator II and a digital Viewsonic monitor.
I connected the monitor to the DVI port on the port replicator and got it to work OK.
The fn-F5 key would switch between the laptop display and the external monitor.

Then it stopped working, and I can't get it to work at all. F5 just recognises the laptop screen.

If I connect an analogue display, it's fine, and I can switch between the two screens without difficulty.

The oddest thing is that, if I reboot while the Portege R500 is docked, the digital monitor starts out displaying the boot sequence, but then the signal is lost once the display stops showing the progress bar (in low resolution).

I spent an hour on the phone to support on Friday, and it got me nowhere.
They finished up saying that it should never have worked! So what's the DVI port for then?

Any ideas?

David

Answer:Portege R500: external monitor doesn't work with Port Replicator 2 and DVI

Connect your monitor directly to your notebook and see if you it is recognised and you can switch via FN+F5 between the two displays.
If it works, then connect with port replicator and try again.

Maybe it is best if you reinstall display drivers. Could be that there is a new one too on the download page.

Dell engineers have appeared to have overlooked a setup on the new m5510 precision laptop.  Originally found on a laptop and pro support was going to send out a new motherboard and lcd, however I reproduced the same scenario on another brand new m5510.

If you hookup an external monitor to the laptop via the built in hdmi port and than in windows configure that as your primary (disabling the laptop screen).  Also turn off windows action to sleep when you close the lid.  Now close the lid to use the laptop as a 'docked' computer with the external monitor and mouse/keypad.   This will function fine, however once you try to 'restart windows' here is where the bios is not functioning correctly.

The laptop will shutdown and a white Dell log will popup on the external monitor and stay there.  Than the LED on the leading edge of the laptop will begin to flash an error sequence (2x amber followed by 7x white and repeat).  I am told that sequence references a defective LCD.  The LCD works fine, all diagnostics pass.

The problem appears to be that the computer/bios is not properly recognizing that the external monitor is hooked up (despite it showing the dell logo) and is throwing this error fault haulting boot to the OS.  With the lid closed the built in LCD is deactivated, but the external is definately there the whole time.

If you leave the laptop screen up however the system will properly restart.  IE:  exter... Read more

Hi there!

What I want to do: "...extend my desktop on a second monitor, but, my second monitor is compounded by 2 HDMI TVs and a VGA LCD stage monitor both used as Duplicate setup in Windows 7".

How I have done this (and it works!):

-I have 4 diplay devices (2 HDMI TVs that are connected using a splitter and two monitors both on VGA);
-I also have two "video cards" (GPU): one Amd radeon hd 6570 (with VGA, DVI, and HDMI ports), and Intel HD onboard (aprox. 1GB with VGA output port).
-I have connected the TVs with a HDMI 1x2 splitter on amd radeon's HDMI port, and one of my VGA monitors (this one acts as a STAGE MONITOR for the singer / artist lyrics).
-The integrated Intel HD card has my "Control" monitor attached that I use as my primary monitor (the one that shows me the Desktop and the lyrics control application).

Software aspect of the problem: In Windows 7, I use my Intel HD video card as my primary display, then I can extend on a second monitor the desktop! (The second monitor is my VGA Stage monitor). The Third display that appears in the setup is the HDMI splitter, this one is a Duplicate of my stage monitor. I use: 1680x1050 resolution for my primary display, and 1024x768 for the second monitor... (I know, this resolution is too small for my HDMI TV's... Windows recommends me a 1900 x ... fullHD resolution, but my STAGE MONITOR does not support that much, so I need to use a small resolution).

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.

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.

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.
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've got a program on my Vista machine that prints postage. When I confirm the postage, a window pops up.

No big deal, except it ALWAYS pops up on my primary monitor, regardless of whether I am using the program on monitor 1 (primary) or monitor 2. This is rather annoying.

This did not happen with my old computer in XP.

Monitor is plugged in vga. Toshiba tv us plugged in hdmi. When I turn my computer on it thinks the tv is the vga monitor. If I unplug the tv and have just the monitor it recognises it but if I then plug in my TV. It then switches to that screen and won't return to the monitor even if I unplug my tv.

HI everyone,
I'm having an issue with my displaying settings and I'm hoping someone here can help me to solve this.

I recently had an older HP Pavilion Media Center m7760n Desktop PC rebuilt. The old power supply fried the motherboard so I need to get a new power supply and motherboard. Here are my current specs.

Mainboard : Asus P5QPL-VM EPU
Chipset : Intel G41
Processor : Intel Core 2 Duo E6420 @ 2133 MHz
Physical Memory : 2048 MB (2 x 1024 DDR2-SDRAM )
Video Card : Intel(R) G41 Express Chipset (Microsoft Corporation - WDDM 1.1)
Hard Disk : WDC (1000 GB)
Hard Disk : WDC (250 GB)
DVD-Rom Drive : TSSTcorp CD/DVDW TS-H653L ATA Device
Monitor Type : Hewlett Packard HP w22 - 22 inches
Monitor Type : Samsung SyncMaster - 15 inches
Network Card : AR8121/AR8113/AR8114 PCIe Ethernet Controller
Network Card : AR5006X 802.11a/b/g Wireless Network Adapter
Operating System : Windows 7 Ultimate Professional 6.01.7600
DirectX : Version 11.00
Windows Performance Index : 2.9
As you can see from above, the "video card" is actually integrated into the motherboard.

The computer works perfectly except for one major problem. I have 2 monitors, one is 22" with 1680 x 1050 resolution and the other is a 15" monitor with 1024 x 768 resolution. At the back of my computer I have a VGA port and a DVI port. The 15" is connected to the VGA port and the 22" is connected to the DVI port.

Hi guys,

I'm having a bit of an annoyance with my dual monitor setup. It seems videos will only show on the primary monitor. I tried everything I coud think of in the Control Panel and NVIDIA control panel also but no luck... maybe a DirectX thing?

Any pointers?

Hello, I am considering to buy an external 4K monitor or a LG 38" ultrawide monitor. I am currently running Windows 7 Professional but I could upgrade to Windows Creator Updates if I want to. I heard many complains about scaling issues with 4K displays. I suppose this happens when users are trying to increase the font size so that they could read the very tiny letters clearly. Am I correct? If I use a larger external 4K monitor, say at 40"-49" or a 38" LG ultrawide monitor at 3840x1600 resolutions, I should be able to see the letters without increasing the font size manually. In this case, will I still have scaling issues? I plan to use the monitor for CAD (SolidWorks), programming, Matlab/Simulink, data science, medical imaging, etc. Thank you.

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. I also have a support ticket w/ Lenovo where they suggested switching to Integrated Graphics only in the BIOS. I tried that, no luck.

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.

I have a dell laptop that has 1920x1080 resolution. However, i connect it to an external monitor that has 1920x1200 resolution. Basically almost everything i do is on my external monitor which acts as my main primary screen. Thus i do sometimes open some windows or drag a window or so to the other screen like youtube etc to the laptop screen which is the secondary monitor.


My issue at the moment is everything is way too big on the laptop screen. I want to have 1920x1080 resolution but its way too big. I googled what is my resolution on it and it shows 1536 x 864. Can someone tell me how to change this to 1920x1080? I googled what is my resolution on the external monitor and it does show 1920x1200 which is correct.

I'm trying to use an older flat screen monitor as an extended monitor on my Yoga 900 series laptop.  I have a VGA to USB connector.  The reason I"m trying to do this is that I cannot use Windows 10 terminal server to remote to my clients server because the resolution is so high everything is tiny.  (I have played with the resolution on my laptop; also the scaling, but when I finally get to a full screen resolution I can see, the cursor disappears in the apps I'm using). I can get the external monitor to work in extended mode just fine and the result on the old monitor is exactly what I want.  But when I'm in remote desktop, running Microsoft Access, the screen flickers and after just a few mminutes, blacks out.  I can revive it, but this is not a workable solution. I have a couple of other flat screens monitors I could try - but they are also older.  I'm willing to try them, but don't want to spend the time if someone else has a better idea. Do I need a more up to date monitor or should I suspect the converter cable.....OR is there another solution out there for my 'older' eyes?

Last year, I ordered and installed a Lenovo 19" Flat-Panel monitor (and driver) for my T-61p ThinkPad.  Recently, as a contractor working on an IBM project, I was provided with an R61 ThinkPad and HP 1740 monitor.  The monitor driver that came with the R61 allows me to extend my desktop displays across the R61 screen plus the monitor screen as one contiguous desktop spread across the 2 screens.  The driver that came with my Lenovo 19" monitor only gives me the option of duplicating my T61 desktop screen on my external monitor.  Can I extract/copy the driver from the R61 and install it on the T61?  Or download a free version of the "extended desktop" driver from Lenovo, IBM, or somewhere else?  I've searched the Lenovo site but found no references to driver downloads.

I believe i can just drag each of the icons on my desktop on my laptop screen to my external monitor. So just do this and that fixes the issue right?

Answer:Desktop Icons Rearranged To Laptop Monitor From External Monitor

If you booted up without the external connected, it likely switched the laptop screen to now be the main screen. Just go back in and double check which one is set to main.
I run dual screens on my laptop but leave the laptop screen as main. My external is a smaller screen than my laptops 17 inch screen. It's a portable 15 inch USB screen.
I on occasion boot up my laptop without the external connected. Having the laptop screen as the main screen helps in this situation.

I am comfortable that Windows sees the monitor because clicking on Display Settings shows two displays. If I unplug the HDMI cable, only one display is shown.

I have confirmed that the monitor works by trying it with another laptop. I have also changed the HDMI cable between the laptop and the external monitor.

It's so dark on the brigthest adjustments that it is impossible to work on. I have downloaded latest driver for support, but still same problem.

Hi, few days ago screen on my notebook Probook 6560b  with discreete GPU 6470M went black.  Monitor does not have any backlight and also there is no picture on it (looking at angle...so it is not faulty backlight). Pulled all devices out (HDD, CD-ROM) but monitor still remains blank (no BIOS screen). On external output (VGA or DP) there is pictrure, but it can not load any Windows (I have dualboot Windows 10 and WindowsXP). In Windows 10 shows error: VIDEO_TDR_FAILURE What failed: atikmpag.sys. In Windows XP, also blue screen with error in atikmpag.sys. So, I booted in SafeMode and remove Radeon HR6470M driver and put Standard VGA driver. Now PC boots to OS, but still only on external monitor. Tried to reinstall drivers, but it always fails with blank screen and PC freeze.With some many tries and restarts, in one moment notebook monitor starts to working again. But only up to next Windows restart.I tried to put new HDD in it and install fresh Windows...but same thing. Booted from live linux distro...only external monitor works. So, as I can see, external monitors on VGA or DP can work but only with generic VGA drivers. OS correctly recognize graphic card, but when driver is installed external monitor also goes blank and windows freezes (not responding on caps/num lock, no longer pingable on network).As in one moment internal monitor went back online it seams that maybe is some bad connections...but where...GPU or video memory? Also tried HP diagnostic...

I only used external monitor occasionally so I decided to wait for nvidia to fix the problem (rolling back to previous nvidia driver version did not help). Well now after 3 new version the problem persists. I tried using  the hot key on my keyboard to change between 4 different monitor-laptop setups (only laptop, only monitor, resize..) and it did not help.  I tried recording my laptop screen when I pluged in the external monitor and the video is normal (it isn't black). I then opend nvidia control panel to see if it recognises external monitor and recorded the screen. My external monitor (samsung) was recognised.Click for video on youtubeIn between black flashes i pluged in/out the external monitor.Translation for "zaslon na prenosniku" : laptop's screen. So any idea how to resolve this problem ? Thanks in advance.

Hi,

i have a notebook lenovo y570 that has a intel 3000 and a nvidia gt 555m card. My external asus vg248 monitor used to work through hdmi, but now it doesnt. I test with another laptop and the monitor works through hdmi... i must have changed some setting in my lenovo. The monitor says no hdmi signal.

I think something is wrong here:

help please!!

See if this helps:

Extending the desktop to the attached monitor with Microsoft Windows Right-click the desktop, and then click Properties.
In the Display Properties dialog box, select the Settings tab.
Click the Display list and select your external monitor.
Note: For help identifying the monitors, click Identify.
Select Extend my Windows desktop onto this monitor, then click Apply or OK.
