Hello, I have a 20 inch LCD and it seems to work bad it turns blank (goes black) every time i want to play a game. or sometimes i am not in game and it stills goes blank but not that much as it does in game.

I also had this problem last year but for some strange reason it vanished away but after a couple a months it back..
Are you sure it is the monitor and not the video card? Have you tried that monitor on another computer?
