The screen on my Aluminium MacBook gets progressively lighter towards the bottom. It's easy to see in the attached photograph. In the background of the photo a NEC 20WGX2 and in the foreground the Aluminium MacBook. Of course it's terribly annoying. As a document is scrolled though, coloured heading change colour jarringly. And on low contrast web pages (i.e. light coloured text on light backgrounds a la Apple) the text on the bottom of the screen is noticeably more difficult to read. In essence there is no such way that you can position the screen and your head so that the colours on the top and bottom of the screen look even remotely similar. I am now on my second MacBook and the screens on both, 9C8C panels, have behaved exactly the same. The first MacBook was manufactured in the 42nd week and the second the 45th week. Before I send this unit back for another replacement has anyone else noticed this on their MacBooks? Do I have unrealistic expectations? Edit: I took the first MacBook in to the Regent Street Genius Bar where the Genius agreed that this didn't seem quite right, but this could simply be due to unfamiliarity with the new MacBook's screens. The display models didn't seem to exhibit this flaw either from what I could tell, but it might've been masked by the overhead lighting. Thank all.
