i bought the 2009 refurbed 27"er and returned it 3 times due to yellow screen problem. for the 4th replacement they decided to send me the new model. i have the 3rd and 4th replacements sitting here side by side. the 3rd replacement, which has a yellow corner is light years better than the new one. the new screen doesn't have yellow corners...it's a perfectly consistent yellowish brown tone. the older one has a yellow corner, but is much more illuminated and very balanced white. the max brightness of the new one is only 3/4s of the max of the old one. i tried configuring it to no avail. are all the new models like this? it's quite a bit snappier, but the screen is worse than the last 3 that had yellow patches? it almost seems like it was a return and it shipped from cali rather than asia?
