I noticed a problem with my U2711. I there is a very very noticable blue line right down the middle of the screen when displaying certain grey tones. THis particular grey tone produce several blue lines. This is a picture taken by a crappy iPhone 4 but sufficient to display the problem. Now im going to ask is this normal, I am guessing not. I have revision A00 of the U2711, does anyone have this problem? Just make a color graident and drag it across the screen to check. I guess im going to call Dell tomorrow to look into this. Good thing Dell has a "at your door" serivice.
