I currently received a replacement for a rMBP because my current one has a Dirt Screen Effect, which was formed in a line instead of splotches. Really bothered me in the middle of my screen. (also has bad discolouration from backlight bleeding. My dad is a photographer and he noticed it himself) So my replacement comes, everything seems perfect, no DSE, but while checking for the DSE effect I found a STUCK pixel. It's TEAL coloured pixel on white, which is BLACK on red, and normal on green and blue. Other then that the colours are even. I was in a situation to decide which one to keep and which one to return... then all of a sudden I'm using my original macbook deciding to keep it, now there's 4 damaged pixels together and its near the middle. Are you serious? This NEVER existed before If I did I would have noticed, it's very obvious. ONE dead pixel cannot be seen on normal usage distance, I cannot see it on my replacement. ( Didn't really bother me but just the thought that a $3000 laptop having a dead pixel is pretty disappointing) But my original one now has 4 damaged looking pixels, I even checked with a magnifying glass. Because it's 4 pixels it is more obvious and can be seen at a farther distance. The reason for me calling it damaged is because with a magnifying glass its not one colour its white on the black background but if you look closely its uneven colour of red green blue. Scheduled a call with Apple to let them know the problem. I might just keep my replacement with the stuck pixel because it's not even obvious on normal usage to save the time and trouble of replacement... In the end, this isn't a post to discourage new users to purchasing the Retina. It's an amazing laptop overall. I love it and would still recommend it to people, I'm just bad luck to get these issues. UPDATE So my third replacement finally came today and it was an LG screen! :O After all the readings about the negative feed backs about LG screen's. From my point of view, nothing wrong with the screen it looks great. I'm casually using it and I don't see any IR. Wither it will stay like this in the future I cannot say for sure, because my Galaxy S2 started to get IR after less then 6 months of use. I was about to keep this rMBP until I noticed a dead pixel.
