I have decided to send my imac 27inch back to apple because of my backlight bleed issue. It doesn't look AS bad as it appears in the picture but you can definitely see it when you have a black screen. I'm going to be starting a photography course soon and think it's unacceptable on a machine worth this much. I have a 24inch imac with a less superior screen and that is perfect with no backlight bleed at all. Before I send it back though I just want to check if anybody else has this problem. The best way to check is to start frontrow or play a DVD so you get the black bars top and bottom. it's a shame because everything else about the mac is perfect and it's a gamble if I get one without any dead pixels or noisy HDD or yellow tinge etc.... but if I do I will keep on sending it back until it's right.
