make sure you dont have like a cell phone near your monitor, lol my phone screw up computers everywhere its funny as hell. Even if its just refreshing it self and checking to make sure time is right it makes monitors flicker, but if it rings anything near it goes nuts. I love ATT wireless. also besure that the monitor is not the problem, a friend of mine was usuing an old monitor and ocasionally it would tint everything funny shades fo make messed up shapes on the screen, it was becasue thecable was messed up.
