Isn't that just the viewing angle? If you tilt the screen backwards, the bottom white block will probably become fully white, and the top one will fade out.
that's the thing, is it's NOT the viewing angle. no matter what vertical angle I look at the screen from, the bottom square is always a dingy beige/yellow color. it's the same problem as the other "yellow tint" threads - the bottom portion of the screen has a gradual yellowish gradient that gets worse towards the bottom of the screen. hence why I pushed the lid all the way back, to make the screen as unobstructed by reflections and such as possible, then took the photo head-on, the way someone would normally look at it.
and yeah, I know the picture sucks, I have a ****** camera and shaky hands, sorry. The basic idea should be clear though. I just don't know if this is how the display is SUPPOSED to look, and I'm having a problem with calibrating it, or there really is a defect out there that I've been unlucky enough to get twice in a row.
Hence why I want someone with a "perfect" HR AG screen, with no yellowing on the bottom, to post a picture, so I can at least know that these perfect screens exist out there in the wild. I do not have any calibration tools besides the built in color utility, and as far as I can tell, I calibrated it perfectly. On each section, I made it so the apple was as indistinguishable from the background as possible, when squinting my eyes it disappeared almost completely. For the gamma and white point I basically left it the same because it looked perfect to me as it was. Did I do something wrong? I hope this is an issue of calibration because that would be easy to fix...maybe someone with a pro calibration setting could post theirs, and I can at least see if it makes the yellow tint issue go away.
Thanks all for the replies.
