So I've wondered what exactly this yellow screen issue looked like. Well my wife's 27" C2D refurb showed today and it has a very evident bell curve shaped yellow area along the bottom to the middle of the screen. Only can tell on white/grey screens. Sucks because the display is fantastic. She is going to work with and see but we installed the firmware update which from what I can tell just attempted to shift the entire screen a few points toward yellow but we can still see it. I've heard the whole 'Its an IPS thing', fine Apple decided to sell a monitor with a tint issue that is not uniform across all their production. How evident is the problem on other Mac's? I don't need a test website or screen, I can see it even during the boot up screen. If the effected percentage is small then a replacement might resolve the issue but I don't want to send/receive if the chances of getting a good one is not high.
