I recently had to return mine due to this issue but after reading a thread here... http://forums.macrumors.com/showthread.php?t=1397887&page=2 I've noticed that you can look at the model of the screen, so I'm wondering for those who do not have the issue to post which one you have as shown... Under Displays - Color, make sure Color LCD is selected and click Open Profile. Then see the info under #17. http://forums.macrumors.com/attachment.php?attachmentid=346995&d=1341691632 Also the next question I would like to ask is when your Macbook was built, enter your serial here in the link http://www.appleserialnumberinfo.com/Desktop/index.php Enter it into the search and hit enter and what I'm looking for is the production date of your Macbook. Maybe it can help determine if the problem has gone away and if really was a bad batch via the difference in screen model and the date that it was built. Or it can determine that it really is the luck of the draw! Also if you don't mind posting the day that you got your Macbook.
