Hi, I've got a new Penryn Macbook (black one), and I'm pretty happy with it. My only problem is the screen - it seems to have really bad colours, which I think may be a contrast problem. For example, I can't see the banded rows in XCode, and I can't see the the grid in Grapher. It just all looks white. Icons on the dock don't look vibrant enough either. It's quite a big problem, because banded rows are a big help for me when looking through long lists, and the grid is very useful when analysing graphs. I can see them if I put the screen way back, so the viewing angle sort of distorts the picture enough to make it look right. Does anyone else have this problem? Do you think I should ask the Apple Store for a replacement? I have tried to calibrate the display, but it only slightly corrects the problem. If anybody has a colour meter and has a professionally calibrated profile, I'd appreciate you uploading it. Thanks!
