    Yeah, it has the LG screen. I did the command and found out.

    Does this mean that the ghosting will occur eventually?

    How do I check for dead pixels?

    What apps should I get? :D

    I don't think there's any direct correlation between manufacturer and screen issues. I believe that's the conclusion of the survey conducted here. I have an LG and it's perfect.

    Dead pixels are most easily identified by looking at an all white or all black screen. Even then, they're hard to see on a retina display. Keep in mind the MBPr display has a dot pitch of 220 pixels per inch. That means there are 48400 pixels per square inch. If you had one dead pixel on your display, a single dot somewhere in the vast array of pixels would be either flipped on or off – meaning it would be a 1/220" static black or white dot.

    Actually the issue is made even more complicated since it's a color display/

    Take a look at discussions.apple.com. The have a long thread going over there, and they've come to the conclusion that it only happens on LG screens. They're pretty convinced that though it does not happen on all LG screens, LG screens seem to be the determining factor.

    I've always checked for dead and stuck pixels on screens by displaying solid yellow, blue, green, red, black, and white screens. Pixel issues will become more apparent when looking at a screen with a single color.

    Yeah I saw that. Yet people here have reported issues with Samsung as well. Can't seem to find the thread at the moment. In any case I don't think it's something that should panic the OP.
