iMac #4 is a winner. I've been staring at this screen for a couple of hours and I do not see any of the yellow gradient that I saw on my old screen. There is almost no light bleed at the bottom and (most significantly) there is no splotchy, inconsistent backlighting like on the old one. I'm happy now. I'll post a quicky pic (I'm sure someone will try to find a flaw here, but I can assure you -- it's spot on) This is week 2 mac. Maybe they are finally getting their sh** together?!
