Here some photos: http://i.minus.com/i1IfWen198Huh.JPG http://i.minus.com/ibfAUmuHcL6J5r.JPG I read about this problem and many people have it. WHY weird in subject? Because I have reversed problem: everyone see it on black screen. I took 2 photos, on white screen and black. And as you can see, it's visible only on white, not on black. Should I exchange it??? This is samsung screen in macbook air 13.
