So I have two problems which may be related. I am running a dual screen set up with a GeForce 9800 GTX+ card. The monitors are a Viewsonic 22" 1080p lcd tv (running on VGA) and an Acer P221W 22" lcd monitor (dvi). I just switched to Windows 7 64 bit a couple of months ago, and for some reason I get these two problems.
Every once in a while, while playing a game, the screen will go black, both monitors just lose signal, and slowly the screens boot back up, kind like they had been turned off. Sometimes I get a little thing in the corner that says "Display Driver NVidia Windows Kernel Mode Driver Version 191.07 Stopped Responding and has successfully recovered. "
I have installed the newest drivers and it still does this.
Also, when I set my second monitor (the viewsonic) to its native resolution, it says "out of range" and won't display. If I set it a size below, it displays but with a giant black bar on the side of the screen. I can't nudge the screen over using the monitor menu enough to make up for the black bar, and if I try to do so using the Nvidia control panel, it moves the screen but not the bar. The only way to get it to display, without squishing it, is to set it to a widescreen resolution waaaaay below the native.
The problem sounds alot like this guy's problem: http://windows.bigresource.com/Win7-Dual-Monitors-black...
Hmm thats weird yeah... The only advice i could give you is unplug one of the monitors while gaming or get a new card... Another thing it could be is the card might be overheating so if you have anyway to measure that you might want to try it out... Sometimes the fan might kick in too late and just overheat that way or your case may not be very inclined to letting air flow through (or your cards fan could be pressed against something causing hot air just to circulate back into it
ANd yeah my acer 24 inch says non-pnp generic as well so that isnt really a problem
