Dual Monitor Issue, Secondary Monitor Is Undetectable
Jan 6, 2010
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.

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)
[code]....
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.When first starting the computer, the 15" monitor was recognized as the primary monitor while the 22" was recognized as the secondary monitor. No problem. I simply went to the display settings and set the 22" to be the primary monitor and the 15" to be the secondary monitor. Unfortunately, this setting seems to reset as soon as I reboot the computer. The 15" is always set as the primary monitor on start up, forcing me to set the proper settings all over again. What's worse is that even after I have set the proper settings, they sometimes revert back when using Media Center or other programs. Worse yet, sometimes the monitors both go completely black ... as if the monitor settings were about to switch but got locked up some how.I'm assuming that perhaps the on board video has a primary port (VGA) and a secondary port (DVI) but even still, shouldn't Windows 7 be able to over-ride this and save these settings so that the monitor settings remain the same during startup and regular usage?

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

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.

I am currently using a laptop connected to my tv. The tv monitor is my primary display and the laptop screen is my secondary, they are extended to each other.I am planning to add a third monitor and was thinking of making it touch screen. Would this work? Everything I have read says that if you use a touch screen it has to be the primary display.

I have an hp dv5215us that I have been running off a power cable with no battery for quite some time now, hooked up to a secondary display, a Dell E151FPp. Every now and then I will unhook the secondary display and take the laptop with me to work without issues. Last night I popped my Win 7 install disk while running XP to install, clicked what I needed to, and let the install disk run. Now that Win 7 is installed, I am running into the following two issues:
1) When the secondary monitor is unplugged, the computer will not power on, let alone boot. No blue lights, nothing.
2) When the computer is on and I unplug the secondary display (I learned the hard way), the laptop powers off instantly, as if I unplugged it from the power source.
I looked in device manager under monitors and it only shows one. I am getting mirror screens now, and under the display options, the resolution options available to me look like those for the secondary monitor, not for the laptop monitor. I installed Windows 7 with the secondary plugged in.
I bought a new battery for the laptop online last night. I know it sounds like a hardware issue rather than an OS issue, but the laptop and secondary display didn't move anywhere since it was running without issues in XP, so unless there was some kind of short or something while the installation was taking place, I can't think of why this would be happening.
Any suggestions?

I have seen a couple dual monitor problems on this forum, but no solutions for my issue. I have Windows 7 32 with dual 4850 cards and CCC installed with Crossfire configured. I am using 2 20" LCD monitors, my primary works fine. Windows detects my second 20" monitor and I have set the resolution and that it should extend my desktop but there is no display.
When windows is loading both monitors display the Windows 7 splash page so I know the signal is getting there. Also I have tried resetting the drivers, uninstalling them, etc. At no point have I been able to get windows to display on both monitors. Any ideas?

Is there any way in Windows 7 to force a specific full-screen program (like a game) to open on a secondary monitor? Or does full-screen stuff only work on the primary monitor?

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.

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 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 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.
