Dual Monitors Black Screen With Power On

Jan 1, 2010

I have 2 samsung22 monitors hooked up to a 8800gtx running on windows7 64bit. The problem I've had ever since going to windows7 is 1 monitor works, the other just black screen with power on. I've gone into nvidia control panel and also through windows and it shows both monitors present but I noticed one monitor is attached through an analog cable but both are hooked up with the dvi cables. Could my card have a bad port?

when I plug in monitor 2 in the r/s dvi port it shows the right side desktop portion of the extended view and when I switch to monitor 1 on the right side dvi port it shows the left side desktop view but nothing comes up when attached to the left side dvi port. I've taken a snap shot of my desktop and it shows both screens. I've tried older drivers as far back to 170's and nothing worked.

Dual Monitors Go Black On Laptop?

Sep 9, 2011

Recently I've been having issues with my laptop and dual monitors. I have been plugging my laptop into the DVI port of external monitors. After a few days, my external monitor would lose signal if I selected to show the desktop only on monitor 2, but now, whenever I plug in my second monitor, both my laptop monitor and the external monitor go black. I've had this happen with two monitors now, and I can't think of what could cause this. Can repeatedly plugging in a monitor break it?

When I Hit Power Button, Screen Goes Black

Dec 22, 2009

I am seriously at my limit spent 3 days I still cant figure it out, done probably 100 reboots. Contacted ASUS Support they are useless still in contact with them in troubleshooting this matter.

This is my issue.

When I hit the Power Button my screen goes black, before a bios revision it would just reboot my computer. YES I have set Power Options, Power Button to shut down computer.

I noticed I am missing a Sleep Button Action as its not in my menus. Maybe this could be a leading reason why this is happening? Anyone know how to get this option to show up?

I have used another computer cases front panel and same issue occurs so it cannot be my front panel.

I have a gut feeling the OS ACPI is completely being ignored when it comes to what the Power Button should do, if I set it to Sleep/Hibernate/Shut Down SAME thing still occurs.

I have got the Power Button to work successfully maybe 8 times out of the 100. It actually Logged off, Saved Settings and Turned of Computer as what I am trying to get it to do.

I have reinstalled the ACPI driver from ASUS but nothing changed. Have the latest BIOS Revision as well. I have removed battery and cleared CMOS as well. Also loaded default BIOS settings.

My System:
HAF 922
Phenom II 955
M4A79XTD EVO AM3
G Skill Ripjaws DDR3 1600
750GB WD Black Cavier
1TB Green Cavier
320GB Cavier

Logitech Illuminated Keyboard (Maybe can use ACPI I think dont know if it can conflict?)

Weird thing, guy at ASUS told me to set it to "S1 Only" in BIOS and it actually worked twice, third time I hit the power button it went back to same behavior.

I noticed my chances are higher for it to turn off properly when the power options advanced settings window is open for some reason.

I hope someone knows how to fix this.

Dual Monitors On Win 7

Oct 26, 2009

I have dual monitors, one on my laptop and another bigger monitor for when I am docked and at the office.

Under XP I had it set so that when I closed the lid on my laptop, the lapto screen was shut off and all files that were subsequently opend were opened to the main big screen.

It appears now that when I close the lid the screen stays on and if there was a window showing on the laptop when the lid is closed it does not automatically switch to the big monitor. It used to under XP. Is there a way to duplicate this behavior in Windows 7?

There are times when I want to use just one monitor and shut the monitor built-in to the lap top - off. Is there an easy way to do so?

Virtual Gap In Between Dual Monitors

Apr 9, 2011

I just installed a 2nd video card. It's running perfectly fine, except now on my dual monitor setup, there is a virtual space between my monitors. (This space shows on the Windows "screen resolution" tab. Practically, it means that I have to move my mouse a lot more to get it onto the 2nd screen, rather than it just being right there. I can move the screen (on the screen resoltion tab) to be right next to the other screen. I'll press save/apply and then it just pops back to the same place it was with the gap still there. I've tried doing it in the nVidia control panel as well, with the same problem (pops back). By the way, even though I installed the 2nd card, both monitors are plugged into the SAME, OLD (previously working) video card.

Can't Setup Dual Monitors

Sep 7, 2009

I am having a issue setting up 2 monitors. I think maybe I cant run one through my graphic card and my VGA port on my motherboard at the same time.... Right now I am running my monitor through a nvidia 8400 gs but I thought I could run another on my VGA port on the motherboard also.

Attempting To Set Up Dual Monitors?

Aug 29, 2011

im trying to set up dual monitors. Right now i have my main monitor as my LCD tv, and i have a vga splitter from my only vga port sending out two vga cables, one to my tv and the other to the monitor my computer came with. im trying to use the monitor it came with as my second monitor where i can do things on both, but its only cloned from my main one. when i go into control panel> appearance and personalization> display > display settings > detect , it will not find my second monitor. So do u need 2 vga ports for this to work? or is there anything i can download that would allow me to use the second monitor as its own and not a clone? this probably sounds really confusing so if i have to reword it i will, just trying to find out if im wasting my time by trying to do this

No Dual Monitors After Powersave

Feb 1, 2012

I have dual monitors that work perfectly at windows startup.After leaving the computer alone for sometime (after powersave has occured on the monitors), I arrive back to the pc to find only one monitor returns from powersave (the same monitor everytime) Rebooting the system corrects the problem; or entering the device manager and selecting "scan for hardware changes" will also correct the problem.I've updated the video card to the most current drivers possible and do not know where to go after that. It's very annoying and have the exact same thing happening with a PC at work with completely different hardware.

Dual Monitors - Only One Works At A Time?

Aug 3, 2010

I've recently switched from Windows Vista to Windows 7 x64. I use the word switched instead of upgraded because I formatted my old drive instead of installing over Vista.I have been using two screens for forever now, both LG Flatron L1750HQ, both are digital and have served me well. My graphics card is an NVIDIA GeForce 8800 GTS, which has two digital outputs. I have the latest NVIDIA drivers, and I have the drivers for my screens (though they are old, June 2007, and I can't find any newer ones... which might imply an EDID problem? Dunno). I have also run every Windows 7 update known to man.To describe the problem: only one of them ever works at a time (which implies the screens themselves are okay), and both outputs work as well. To top that, Win 7 does recognize I have a dual display, but one is always in digital power-saving mode (no signal, I guess).When my computer boots up, the left screen shows the boot process, while the right one has no signal. When Win 7 boots, its the other way around.

In the NVIDIA -and- the Win 7 control panels both screens are visible, shown side by side, and set up properly with and without the screens' driver, but that does nothing to solve the problem.I've also examined my BIOS, but I doubt its anything to do with that since I haven't touched my BIOS in ages and it worked just fine on Vista. I'd wager that if I go ahead and install Kubuntu on this machine, I'll get my dual screens back, but I don't want Kubuntu.

Background Won't Span Across Dual Monitors?

Jan 15, 2011

I have two 4:3 monitors side by side. Both of them are set to 1280x1024. My desktop is extended across both.I downloaded a 2560x1024 image and set it as my background. Iwent into personalization/etc. and set it to 'Tile' as Google results repeatedly said I should.No matter what I do, tiling just makes four images appear, two on each screen.

Dual Monitors And Photo Screensaver

Nov 10, 2009

I have a dual monitor setup. In XP the photo screensaver would display pictures on both monitors, alternating between them.

On Windows 7, most of the image is on my left monitor (which is my secondary, extended display). Some of the image shows on the main (larger) monitor.

I would like the images to show on the big main monitor.

Anybody have any ideas?

Cannot Get Wallpaper To Stretch Across Dual Monitors

Jul 17, 2010

I have 2 Samsung SyncMaster 2243 monitors running off of a ATI Radeon 4670 graphics card.

I have downloaded some wallpapers that are wide enough to cover both monitors (large panoramas atc). But it just displays whatever will fit on my main monitor and duplicates it on the secondary monitor (This is only the case with my wallpapers, not the rest of the desktop: shortcuts, start menu etc.). I'm sure this is just a user error on my part.

edit: If I choose the "tile" option. It will ALMOST do what I want. The picture will extend across both monitors, but if it is not quite long enough/tall enough it will start the tiling.

Feature Funky With Dual Monitors

Jun 17, 2009

I have to have dual monitors and 7 works great with them. One of the cool featurs of 7 is to be able to put up two reading panes side by side. If you have not seen this it is done by opeing say 2 Word docs. Pull one left and one to the right. They will each fill 1/2 the screen side by side. When I do it with dual monitors - let's just say it does not give the expected results.

Odd Configuration: Setting Up Dual Monitors

Nov 1, 2009

Ok, so I just added Windows 7 to my lineup. After an epic battle with permission problems between XP and 7, I finally managed to fix it and have moved on to a slightly more odd yet annoying problem- my dual monitors.

The way I used to have my monitors set up was my monitor on the right had my task bar and icons... but the monitor on my left was the main monitor. That way when a program opened it would open on my left monitor (which is right in front of me) while still allowing me complete access to everything under my taskbar and all my icons to my right.

Is there any way to do that in Windows 7? When I select "Make this my main display" it moves the task bar over to that monitor, which is annoying. Any suggestions?

Note: for those of you curious on how to do this in XP or Vista- pick the monitor you want to be your main monitor (the one programs open on) and pick the one you want to have your taskbar. Let's use my setup- main monitor on the left/Task bar and stuffs on the right).

- Go to display, right click on the right monitor and uncheck "attached". This will turn it off. Now all you have is the left monitor with taskbar and stuff all over it.

- Right click the right monitor again. Check "attached" AND "Primary". Click apply. Right monitor turns back on. Everything refreshes and task bar is on the right monitor.

- Right click left monitor and click "Primary". Task bar + icons are still on the right monitor, but now all programs open on the left one.

Windows 7 Will Not Show Dual Monitors

May 31, 2012

As of right now I am running Windows XP Pro 64bit cause Windows 7 will not display dual monitors, I tried a combination of things and nothing... But xp shows them both with no problems and I didn't even have to install my driver for it! Windows 7 uli when I stall the driver cause i have the same disk that came with the video card what's the deal-le-o here

Running: on board video is Nvidia GeForce 6100 512mb
PCI card with dual vga ports and 1 S-Video port Nvidia GeForce FX 5200

Not sure if ram has anything to do with this but I have 3.25gb ram but both windows 7 and xp only show 2gb I'm thinking that might have to do with that 1.25gb are not of the same as the 2 1gb sticks.
