Hey folks, received a brand spanking new 2011 27" iMac today and it's a fabulous machine except for one problem... yep, the dreaded yellow tint screen is in full force. This sort of thing normally doesn't bother me but it's really quite bad, to the point that the bottom of the screen looks like a totally different colour temp than the top. Looking to make a genius bar appointment ASAP but is there anything I can do to try and relieve the problem? I'm assuming that the screen doesn't need running in or anything like that and haven't been able to get anywhere with calibration. Doesn't seem to make any difference where I'm sitting or what angle I'm looking at the screen from either... really annoyed by this as it's a BTO machine and my Macbook Pro is currently on its last legs (hence the new iMac). Any thoughts or advice would be gratefully received.
