Hello,
Im using a GeForce GT 640 on a Windows XP-machine, dual display (DVI). When im tampering with any window (just draging it around on the screen) The secondary display has a tendency to flicker, and some times go black for a second or two. Now to the strange part. If i go into "Nvidia Control Panel" --> "Adjust Image settings with preview" and drag the slider to any of the three presets, the screens works perfectly for about 30 seconds and then go back to the flickering, if i drag it to another (ie. the one i had before) it stops for another 30 seconds. I have tried diffrent drivers with no succsess.
Any input would be appreciated.
