Dual Monitor Problem On 7900GT
Aug 15, 2009
I have a fresh install build 7100 on my PC today. I have a GeForce 7900GT and 2G of memory. I had a previously working dual 24" Dell monitors working under XP on the same rig of the DVI ports.
Problem is that I can only get one of the monitors to work at a time off the card. Soon as I plug the second monitor in it takes a second for the monitor to sync and than the GPU fan kicks on and the monitor cuts to this stair step pattern. The second monitor that I plugged in will show an extended normal desktop. Unplug the monitor and the primary goes back to normal.
I got the most recent driver for my monitor and video card off windows update. I have also tried downloading the NVIDIA WIndows 7 drivers for 7 series cards but, that caused the same problem to manifest during install and caused some video instabilities.

I was having a problem with dual monitor using 7127 build. But only when I use newest NVIDIA drivers. My tv just flashes a few times, and I can see that fish a couple of times, but then it just goes to like no signal. If I use default drivers which are installed on windows install, then it works fine, but then I dont have NVIDIA control panel and some other features.
My video card is GF 8800GTS 650M 512MB DDR3 DUAL DVI TV PCIE. I would like to know if anyone else is having this problem and If it has been fixed in the newest build, so I could be arsed to do a clean install.

I am running a dual monitor setup with my TV hooked up via HDMI to my laptop.
Everything was working fine before, I always had the laptop as my main display yet I could play a video or a game fullscreen on the TV.
Since a couple of days, as soon as I put something in fullscreen, it immediately goes on my laptop, regardless if it's open on my TV or my laptop. I don't remember changing/installing anything that could've changed that...
I checked a bit in the AMD vision software and the Windows control pannel but I can't seem to solve my problem without switching my TV as the main display. I also made a quick search on google as well as here but the problems were mainly with Flash, which isn't in cause here.
Here are my system specs:
Toshiba Satellite L75D
Windows 7 home premium 64-bit
AMD Radeon 6520G

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 standalone 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.

This computer is running an ATI Radeon HD 2400 Pro. It does support dual monitors...(I've had dual monitors active on this card before, but never on Windows 7.) But since installing windows 7, I can't even get it to detect the second monitor. I want to run the setup with the CRT as the primary monitor and the HD as the secondary.

I'm using a television (32p) as a second monitor in extended mode so that I can watch a movie in the TV and play a game in the monitor (this was my main goal). Monitor and TV lays in two different ambients, both connected to the same pc, one by normal VGA cable and the other by HDMI. I managed to differentiate the audio output so that VLC player sends it's audio to the HDMI (so that only the TV plays it) and the rest of system sounds, media players and games outputs to the speakers (basically only the VLC audio is directed to another output device). I reached my goal so that I can watch a movie fullscreen in the TV and play a game in the monitor fullscreen too without any interference from one another (nor audio or video).
The thing is, because I have the TV in another ambient I can't actually see what's going on in it, as I just "throw" the VLC window to the TV from my main monitor. And here's the question: There's a way to see the TV's desktop in my monitor? Without having to set it as main monitor so to not really switch between desktops.. The perfect thing would be if I could see the TV's desktop in a window like in remote desktops applications.

Friend has a dual monitor and wants to play a game across both of them, the problem is the option doesn't appear I think it might be the new driver he installed. I tried installing Hydravision which has an option to span across displays but it doesn't work can anyone help?

I have Dual monitor setup running on a NVIDIA Quadro FX 4500 driver: 191.00 (latest). Second monitor will not display.
Via Nvidia tool as well as control panel I get an error that the "configuration cannot be saved" when trying to extend my desktop.
Second monitor shows up as a choice, but will not display even when selected.
Monitor displays "data" during boot screens.
Any solutions on how to get windows/graphics card to see both monitors?

I have just built a new machine the last three weeks and finally last night I was ready to complete my final transfer from old to new computer. That meant adding my 2nd monitor to my new machine.
My graphics card is a GeForce 9400gt. I have the latest drivers from Nvidia's web site. New machine with Windows 7 has been working for 2 weeks with a single monitor.
Both monitors are fairly new. The graphics card has one DVI and one VGA input so I must set up my dual monitors that way,
My problem is when I hook up my 2nd Monitor I get the BSOD. I will spend 1 more night trying to fix it but that is it.
So my questions are as follows:
1. Does anymore have any ideas why The BSOD comes up when my 2nd monitor is plugged in?
2. Does anyone using Windows 7 have a working graphics card with a dual monitor set up that is working? If so, what card is it? I may be buying one tomorrow.

i have:
Windows XP pro (32 bit)
nVida GeForce FX 5200 has VGA;DVI;SVideo
ok heres what i did b4
i had 2 monitors one vga one and one dvi one and i hooked it up and i had i good dual monitor setup but when ever i loaded some programs the would give me a bsod screen and restart for example fsx dark basic and others that change resolution.
now....
i re installed nvida drivers and there updated (i think)
i have the DVI monitor hooked up right now with 1 display only
i have the desktop manager software enabled and running and the Nvida control pannel running.
and what i want to now is that i want to have a horizontal span setup (reason):
ok well i have seen that FSX can run on 2 monitors and that you can have a really cool display with both displaying images can i do this on a dual monitor setup or not or do i need to get a better card (preferably not)?
What to i do now?
ok so do i go to set up multipul monitors and do it that way or is there another way to do it better theres one last question, well i herd from a friend that in the display options like when you right click in the desktop then goto properties then settings. the friend said that there was an option to enable dual monitor support. before i had my setup i did not see that option and neither do i now im guessing that i don't have 2 monitors hooked up now.
I am obsessed about getting this to work so if i am making any of you people here mad i'm sorry and Thank-You for the help that you have given me recently, btw i got my processor to work and i got it hyperthreaded..

Anyway i have 2 22" LCD Monitors and when i plug them in. Windows 7 does this weird thing were when you select the option to extend the desktop spanning from left to right. Instead of simply scrolling from the left screen to the right screen with your hand as you usually would with any OS, Windows 7 BETA somewhat reverses it were you have to scroll to the left from your 1st monitor to get the 2nd monitor. (sorry if this is really confusing im having a differculty writing this also haha)
And if you select your monitor on your left to be your primary monitor, it will wont do that it will move the it to your right monitor instead so i decided to physically switch the monitors around on my desk to get it normal. but i don't like the idea of my computer telling me what to do hahaha.
I know its a beta OS but its still based somewhat on vista. ive got the latest drivers for my graphics card and my graphics card is a NVIDIA 260GTX so its pretty meaty and it can do dual monitor fine on other os's.

I've searched the internet far and wide as well as these forums and have not been able to find the answer. Unfortunately, my sister-in-law's dog killed my 2nd monitor so I haven't been able to test on my own since installing the RC version last week. (new monitor will arrive next week)
My question:
If you RDP in Windows 7 from a computer with dual monitors to an XP computer with dual monitors is the multimon support available?
I want the session to feel as though I'm at work with dual monitors.... not just spanning the 2 monitors. My work computer runs windows xp.
Currently the only way to get this functionality in xp is to use the span command and to use add-in 3rd part software that does not work that great.

okay so I am at work and whenever I want to maximize a window to fill the left side of the monitor, it for some reason maximizes and centers in between both the monitors. Does anyone know how to fix this? I know that probably didn't make much sense, but I attached a picture to show what I am talking about. I was trying to maximize this window by dragging clicking it at the top and dragging it all the way to the top to maximize, but it centers in the middle?

I'm running Windows 7 on a Compaq Presario CQ56.I've been having trouble with the multiple display settings changing on their own on my laptop.

I havan't downloaded anything recently besides windows updates.

I have two monitors, and would like to setup a different wallpaper for each monitor while retaining the expanded screen option. How to go about that? I am using a Radeon 4770 HD if that helps.

I'm having a small problem in Windows 7, and that is the two screens I am using have different resolutions & aspect ratios (1680x1050 and 1920x1080).
The problem is my second screen wallpaper stays the same size as my main monitor (1680x1050) instead of filling the entire area. I've tried all the different wallpaper options, Fill, Stretch, Centre, Tile etc, none seem to do anything. I have seen DisplayFusion (DisplayFusion: Multi-Monitor Taskbar and Desktop Wallpaper*|*Binary Fortress Software), but if possible i'd like to fix this little problem without third party software.

I have an external monitor, actually a TV connected via S-Video cable coming out of the back of my video card. My TV is my second desktop. All of that is fine. The problem comes in when I log off or "switch users" (there are no other user profiles on my computer - I only log off or switch user to make sure the kids can't get on without my permission - they don't know my logon code), the TV loses the picture and goes grainy, but when I log back in, the TV does not "kick in" again. The only way to get the TV to display the second desktop after logging out or switching users seems to be to restart the computer entirely. If it reboots, it picks up the TV as second monitor again.
If you simply log in again, it does not pick up the TV as second monitor. Is this related to some setting that says the TV should only be the second monitor on the admin's account and not for "all users" or something? It is annoying to always be restarting my computer to watch a video on my TV. By the way, in all cases, the "Display" settings in control panel show the TV as the second monitor. But looking at the actual TV, all you see is a grainy screen that obviously is not being fed any clear signal.

I have just installed a dual monitor set-up on my PC. 1 connected with DVI and the other with HDMI. While using both screens 1 has a yellow tint (the right screen) but when I switch back to using just the single monitor (left screen) then that screen has the yellow tint?

I am running Win 7 Pro x64, i7, MSI Twin Frozr II R6870 1st Monitor is a Dell SP2309W (dvi on video card to dvi on monitor)2nd Monitor is a HP W2338 LCD Monitor (dvi on video card to hdmi port on monitor)The 2nd monitor (HP) goes off after a few minutes, but if I'm playing a video on that monitor the sound is still plays, so I know it's still running in the background. I noticed that the picture on the monitor doesn't fill the whole screen like my 1st monitor does. So I checked the resolution and it's set the highest resolution it will go.I've checked the power settings by setting everything to never sleep or hibernate.I also checked the Graphic settings, but everything looks fine. I also updated the drivers for the video card. Both monitors are set to 60htz because that's the highest it will go.

I'm setting up Dual Monitors on my HIS Radeon 4870 1GB GPU. This GPU has 1 x VGA and 1 x DVI output. I have two identical ASUS VW222u monitors. I have installed the latest ATI Catalyst Suite and drivers for this GPU and have Windows 7 up and running with BOTH monitors.
My issue, however, is my primary monitor (DVI output) is running at my ideal resolution of 1680 x 1050, but my second monitor (VGA output) can not run at this resolution. It is only allowing me to choose from a small specific number of resolutions, and 1680 x 1050 is not included (closest is 1600 x 1200, IIRC).
The ATI Catalyst Control Centre is telling me the primary monitor is my ASUS VW222u (Digital), which is correct, but my 2nd monitor is only described as a "Generic Non-PnP CRT Monitor", despite installing the correct monitor drivers etc.
Is this because I am running this second monitor of the VGA output? Will that cause my monitor to not be able to produce my desired 1680 x 1050 resolution? And will running it off the VGA output mean It thinks its a CRT?

Looked around but nothing specific. If there's another thread with the answer feel free to post the link and smack me...
Have a Dell GX620 (desktop: mid-size that requires low profile PCIe graphics card) running Windows 7 Pro 32 bit. Looking for a low profile card that will support dual DVI (expecting a Y cable) with dual monitors and extended desktop with 2 different displays. Dell 22" widescreen and Dell 19" digital.
Can go VGA if needed but would like to go all DVI.
Another thing I'd like is certified Windows 7 drivers vs just compatible or something that I have hack to make it work. I tend to build out a box and let it run a few years with as little tweaking as possible...

I recently installed an Nvidia Quadro CX card under Windows 7 (risky, I know). Although I'm using the latest drivers from Nvidia, I can't get the second monitor to display through the displayport-to-DVI adapter.
I can swap cables all day long and each monitor works fine with the DVI connector; it's just that nothing is detected when plugged into the second output (displayport).
Has anyone else run into this problem with Windows 7 build 7000?

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?

On my Windows 7 partition I am unable to use my laptop screen and my 27" LCD Samsung TV as a monitor simultaneously. This was not an issue on my XP partition. I have updated drivers on my video card to no avail.
My TV is connected via a VGA cable. If this cable is connected when I turn my computer on, it will display on the monitor only (but at a much lower resolution than my XP partition allowed) and I am unable to switch back to my laptop monitor without restarting. My display settings wont even recognize that both are connected. Any help would be greatly appreciated.

I currently use my computer to watch HULU shows on my HDTV, and it works wonderfully. However, with multiple monitors, I was hoping to be able to watch TV and work on other things simultaneously.
The problem that I'm having is that if Hulu is in Full screen on my TV, and I try to do ANY Thing at all on my other screen, Hulu exits full screen mode. This is Suffice to say, a pain in the butt. Now I can not multi task, I either have to use my computer, or watch TV, and not both.
What I was wondering was, is it possible to completely separate the control between the windows, so that you would instead of dragging the mouse off screen, press something more of an alt+Tab keystroke to switch between them?
That way, not only do I not lose the mouse pointer momentarily if I touch the edge, but I'd also not effect what one screen is doing while working on the other. Maybe even enable multiple mouses and keyboards to be used and assigned to their own screen so that multiple users could even use the same computer.
one could type homework while the other checks their email or plays a game. With the multiple cores in most computer nowadays, this type of multitasking should be a snap.

I have recently bought a new computer and with it i got a lcd monitor. As i alreadfy had a computer i thought i would start using a dual monitor set up in which i can have two screens doing different things, for instance one monitor plays a film while the other is on facebook. how ever when i received the computer it only had one AV monitor port on it. This meant i couldnt do a dual set up for even use the LCD monitor to its potential. So i bought a AV splitter cable to plug both my monitors into one port. but this just left me with two monitors doing the same thing and having to use the bad resolution from the old monitor on both monitors.
