Can anyone else with a 27" ACD tell me whether they have any image persistence with the display? I just got a new one, and if I switch the background to be a solid gray color (a dark color but not black), and then I place a few browser windows open all on the Google homepage. After 15-20 minutes of not moving the windows, if I view the desktop, I can see the "burnt-in" or image persistence of the Google logos....very faint. If I don't put anything back on the screen, they go away in under 5 minutes. I had this issue once with an old 23" ACD....and I've read all over the web where it's a common issue with LCD panels.....but I'm not sure whether it should be happening so quickly with this ACD? Not sure if I should be taking it into Apple or not. Generally I would never see it unless I had the gray background and had a bunch of windows on the screen just sitting there. This is my 2nd ACD, after the first one had something trapped under the glass. Thanks! -Kevin PS. Also, anyone have any good color profiles for this display? Very blue out of the box......don't have the cash for a calibrator right now.
