I downloaded a new game (star wars the old Republic) yesterday and when i tried to open it my monitor went black and gave me an input signal out of range sign. Restarting didn't fix it- i can start in safe mode fine but i can't manually change the monitor settings there because it just gives me the safe mode settings.
I've had a similar issue with a different game where nvidia control panel decided to 'optimize' my settings but put them out of my computers range, but in that case i only got the monitor issue when the game was open-i could minimize out and have the monitor come back on.
I tried uninstalling my graphics drivers in safe mode and restarting- which worked for a moment but then windows automatically downloaded a driver and the screen went back to black.
I'm running windows 7,and my graphics card is an nvidia geforce gtx 660
