i got my iMac this june, so i'm not sure what generation that makes it. (somone let me know plz) anyway just today i noticed I have some horizontal lines going across it. very faint and hard to notice, but i'm anal and i noticed them. My first instinct was to find out how to degauss this monitor. but apparently you can't on this thing. 2 possible reasons i could give to this problem. 1. my monitor speakers on both sides of my screen, they are m-audio bx5a. so they are big, but ive had them for months now, and just today the lines appeared. which leads me to belive 2. on mistake i started up call of duty 4, and forcequit it as it was loading. After some time i noticed the lines. next time i opend the game it said it was shut down inpropperly and i would have to open it all weird. any ideas? i'm gonna call apple but does anyone have experience with this, could it be a virus? 24 inches, top of the line video card, i think its a geforce something. 500 gb hd, leapard.
