So what's everyones thought on the yellow hue problem on the 2012 iMacs? I just got mine. I immediately noticed a yellow hue on the bottom half of the screen. It's annoying me already. It's only when the display is on a certain angle though. Usually only when I lean in close. How wide-spread is the problem? I don't want to return it and wait another 2 weeks for a new one if it's just going to have the same issue. Any thoughts?
