My girlfriend and I have mbps. Mine is 2ghz with 256mb video and hers is 1.83ghz with 128mb video. I have recently noticed that my screen displays colors differently. White is slightly brown and black is grayish. On my girlfriend's mbp the white and the black are perfect .Did anyone else notice anything similar? I was planning to get the logic-board replaced in the near future. Do you think Apple would replace the screen?
