Ok i own a dell 2405, i'm not sure if i have blacklight bleeding or is it my video card over heating. When this so call 'bleeding" occur, is it permanent or a come and go thing. And am i suppose to notice this while i'm in window desktop. Well i'm asking this is because whenever I play world of warcraft. I got this rainbow color thing on the bottom and right side of the screen. But when i alt tab out to desktop is gone and when i alt tab back into the game is still there. And this doesn't happen right away when i'm in game. It sorta come and go. So do you guys think is my LCD or videocard?
