A couple of months ago my monitor started to flicker so i called ASUS support and they were going to send another monitor right out, yeah months later I'm still waiting, anyway I know its not my graphic's card because i just took out my 780ti for a Titan X same problem, it only flickers on the desktop or loading a game but doesn't flicker at all in a game, if i'm on a forum reading something it flickers really bad and the screen hurts my eyes, I have brightness turned down to 52%, is there a fix or update?
