Just the past few weeks ago, I began to notice that at the top of my monitor (about 1/10th of the top half of the monitor screen) would have all glitch like lines. There seems to be 2 stages of it where it's really bad that even when I put my cursor up there, I can't see it. Then it gets better where it isn't so bad, then it becomes normal. I was just wondering if there is a way I can fix this, or what may have caused this? I don't believe it was any type of magnet type thing since I make sure those aren't around. This usually only occurs after stepping away from my computer for a while or leaving it on overnight. It does not happen while I'm using it however. any help would be greatly apprieciated =) I would hate to have to replace my monitor because of it.
