Okay, I've never had this issue before, but I don't know really how to describe what the monitors are doing. It's like lines move up and down across the screen. It kinda hurts my eyes to be honest, but when I turn on vertical sync, it fixes the flickering. Vertical sync for some reason slows the mouse down in the game I play sooo.. yeahh.. kinda sucks.. :/ Is there anyway to fix it? Ive never had this issue before with any other monitor. 1 monitor I have connected with DVI, and it doesn't do the flickering, but the two other monitors I have connected with VGA and they both flicker.
