If an extensive discussion thread in forums on Apple Support is any indication, then there is seemingly a problem with a number of MacBook Pros that are outfitted with Retina displays. The affected Retina displays show burn-in and image retention.
LG Manufactured Displays
John K, who is a member on the Apple Support forums, contributes to the discussion by pointing out that the problem seems to be taking place primarily with MacBook Pros that are outfitted with LG manufactured Retina displays. It has been found that other displays that are manufactured by Samsung seemingly display the colors more accurately, they are brighter and they do not have the same issues with burn-in and image retention.
This helpful terminal command:
ioreg -lw0 | grep \”EDID\” | sed “/[^<]*xxd -p -r | strings -6
will assist you in determining the manufacturer of the display that has been installed in your own MacBook Pro.
This terminal command is used to check whether an LG Screen is on a MacBook Air. If the display code starts with “LP,” then it is an LG display. It has been verified that users of the LG panel see a faint ghosting of the Finder windows whenever they access any PowerPoint slideshow that has a gray background.
Individuals who have a MacBook Pro outfitted with a Retina display and have been experiencing this problem can contact iFixYouri to perform the necessary repairs.
