Purchased a brand new 27" i7 imac a few weeks ago, display is awesome!!! I was using my old 28" LCD monitor from my PC and running dual displays on the iMac. The 28" LCD monitor annoyed me a bit because i could not get the same color/crispness/brightness that i got from the iMac. ( also it has a Matt screen and i am more into the glossy screens ) So i found a used 24" cinema display locally. Paid 600.00 and it came with 2 yrs of AppleCare. It is only 7 months old ( still have 5 months under orignal warranty ) Got home, hooked it up and it had a "hint" of yellowness to it, It wasn't a exact image of my iMacs display...I tried to calibrate it also, but it still had just a HINT of yellowness....Nothing at all major, but enough for me to be annoyed with it. Took it to the Apple store and they are replacing the LCD on it. I am curious, Once they do replace it,Will this most likely fix the issue? I am expecting the 24" cinema display and the 27" imac to look IDENTICAL in color/quality/brightness. Should they be identical? or is that not possible? Does anyone else run a 24 and iMac together and are they the "exact same"? Just curious if i wasting my time hoping for them to be the same?
