I just bought a 15", 2.4 GHz, LED-backlit MBP. I've noticed that there is a problem with the vertical viewing angle of the screen. If I adjust the screen to the most comfortable angle for me, the bottom 1/3 of the screen appears marginally darker/less white than the top 2/3. This goes away if I sort of slouch and look at it from a different angle, but that's not very comfortable. It seems like the vertical viewing angle of the screen is limited. Anyone else notice the same thing?
