Aren't all the replacement screens Samsung only? The thought of having something so new and expensive go in for a repair put me off, but the image retention (had an LG) was getting stronger and worse. I couldn't watch a video without seeing my desktop's ghost for over five minutes. It wasn't just grey anymore, but also certain greens and oranges. It was most apparent with iphoto's and photoshop's default color scheme. Repair was covered under standard warranty (no Applecare), took three days, and because the entire lid is now the part for the screen, I got a new lid out of it. Had a couple minor scratches on the original, replacement is perfect.
Ran stuck pixel single-color tests and stared at it from every angle, no stuck pixels. I did get scared when noticing very faint flashing pixels looking like snow on the Steam forum's grey background. Goes away when gfxcardstatus forces the nvidia. Still, it freaked me out but it turns out it's a known-issue with all Intel 4000s.
