Dual monitor issue, secondary monitor is undetectable

Q: 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 DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

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

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

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

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

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

This is annoying, please assist...

I 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.

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.

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

A: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.

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.

A: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 have the dual monitor thing working and everything. I have my laptop and attached it using HDMI to a HDTV. The problem is that i cant get my desktop to my laptop. The HDMI cable, when plugged into my laptop makes the TV display the desktop automatically. Because of this, when i enable the dual screen, it extends my desktop to my laptop screen, and uses my tv for the main monitor. Does anyone know how to fix 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.

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

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.

A: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.

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.

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

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

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

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

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'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.

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?

A: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. ...

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.

Thanks for your help in advance,

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?

"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?

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.

Welcome to Seven Forums Calathra. Can we start by having you fill out your system specs?

At the top of the page, you will see UserCP (User Control Panel). Click to open your control panel. In the left side, look for, Edit System Spec. Click on Edit System Spec and fill out the information. If you don't know how to get that info, you can use the free program Speccy:

Speccy - System Information - Free Download

We are looking to see specifically, what video card you are using (if any) and how you are setting the dual monitors (through windows, nVidia control panel, Catalyst Control Panel, etc.), so we can help you with this problem. A Guy

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?

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

A: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.

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.

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

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.

my PC desktop is extended across two flat screen monitors (dell st2010 and dell e193fp) however my cursor cannot move between screens - the cursor remains limited to the primary monitor, the 2010

when I pull up the nvidia control panel it appears on the secondary monitor which my cursor can't access

things were fine yesterday - I could move the cursor between screens no problem - now this - strange

Word opens on the frozen secondary monitor: the insertion point winks, but I can't type anything = no mouse action or typing on secondary monitor

when i move the USB mouse from port to port the cursor jumps from primary to secondary screen but still can't move back and forth between screens

computer is a brand new dell xps studio
dual core

drivers updated

any advice will be greatly appreciated

Have you tried moving the mouse off the side that isn't between the two monitors? It sounds like it may have somehow switched the monitor positions (right/left, left/right).

I just upgraded to Windows 8 on my HP Pavillion dv6815nr. I am not having any luck connecting it to a second monitor. I followed the basic steps under "screen resolution", but my computer is not identifying the second monitor. I read that you need to go to Nvidia's control panel to connect to a second monitor, but I cannot seem to find that with the driver I currently have installed. HP's website does not have an update for the Nvidia driver for Windows 8 for my particular computer. I am using a VGA cable if that makes any difference. The computer originally had Vista and I never had any issues connecting to a second monitor. Does anyone have any useful pointers?

Thank you!

A:HP Dual Monitor Issue

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.

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?

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.


A: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.

I take it you have the Microsoft nvidia drivers installed?

These drivers are very generic....

Install the latest nvidia drivers from either nvidia or from your laptop manufacturer.

That should give you the full nvidia control panel.

Good Morning,

I am running windows xp sp3, and am set up for dual monitors. I have one user who is having issues. The screen on her laptop is fine, but the other monitor she is using (should mirror her laptop) the background picture is all distorted and the contrast is majorly off. Other users can log on the computer and it is fine, so must be the individual users settings. However I can not find any setting differences, between users.

Would really appreciate any assistance you can provide...

(not an SA just forced to play one at work)

In general, when dealing with issues that are User Account-specific, one should always consider the option of simply creating a new User Account and transfering the settings from the old one to the new one, as a most-effiecient means of fixing the problem.

Hi Guys,

My computer just had the most recent update and its caused me a problem with my 2nd monitor.

My main monitor is connected via HDMI and my 2nd is via DVI cable both to my graphics card. Since the update the screen still displays in its native 1920 x 1080 but the screen is blurry (not just the text). This was not an issue before the update and both monitors worked great. The 2nd Monitor is a Dell ST2220.

Things I have tried:

Reinstalling the graphics card drivers and make sure they are updated.
Tried to get driver for the monitor through Dell but according to the website Windows 10 did not require a driver for my monitor
Turned monitors on/off tried them separately etc and still seem to have the same problem.

Any help would be greatly appreciated.

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. The game runs normal with only 1 screen.

ps. I run with the VisionTek Radeon 3870 Video card

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??

Hi all,
I have a PC with an ATI Radeo HD 2400 XT video card installed. Until yesterday dual monitors were working. Now, only one monitor works. In device manager the displayed name is shown once whereas before it was shown twice. I have updated drivers and it did work again when I re-installed them until I rebooted. Then only one again.
I am running XP Pro and have no idea where to go next. I did try another card but had the same issue. All other hardware was replaced for testing purposes (cables, monitors etc).

Does anyone have any ideas?
This is the 3rd time I have seen this happen and haven't been able to fix it.

Many Thanks to all

A:Solved: Dual monitor issue

Though, you have a video card installed, does your computer have a presentation manager application or similar application? In addition, it is not about press Fn + F5 or F7 depending on your manufacturing company, it differs to display both screens.
