Are Retina MacBooks displaying screen issues?
If a 56-page discussion thread on the Apple Support forums is any indication, there appears to be a problem with some MacBook Pros with Retina displays. The Retina displays with the issues show image retention and burn-in; others do not.
TUAW reader Joe K. sent us a note about the issue, which appears to be happening to MBPs with displays manufactured by LG; other displays made by Samsung don't have the problem with image retention and burn-in, are brighter, and seem to display colors with more accuracy.
To determine the make of the Retina display installed in your MacBook Pro, Joe supplied a helpful terminal command:
ioreg -lw0 | grep \"EDID\" | sed "/[^<]*</s///" | xxd -p -r | strings -6
It's basically the same command seen on OSXDaily to check for LG screens on MacBook Airs, which will also tell you how you know if you have a Samsung or LG display. If your display code begins with "LP," it's an LG display. Mike Rose has verified that with his LG panel he sees faint ghosting of Finder windows when he goes into a PowerPoint slideshow with a gray background.
Those who own a MacBook Pro with Retina display and see this problem as described in the thread should contact their local Apple Store or AppleCare for resolution.
