I want to start by saying I am extremely OCD. I take meds and everything. I had my rMBP about 2 weeks before I even heard about the screen issues. $2000+ for a laptop (even for a big apple fan) was a big deal for me. I had some sluggishness and discovered turning off the automatic graphics fixed it. In my paranoia about that I still didn't come across and posts about the displays. Once I found out about the displays and how to check if its a Samsung or LG, it drove me nuts not knowing (I had no issues) and I told myself I won't check. Well... I checked. Disappointed to find I have an LG. BUT I have no issues. I have tried all the "tests" and cannot duplicate it. My screen is bright, colors are vibrant and no IR. I'll wait a few more weeks before I get too excited but it doesn't even bother me. And trust me, I'm anal. I exchanged my yellowed screen iPhone 5's 4 times to get a good one. This is just a pep talk that good LG's are out there! If anyone wants any info about it let me know. FWIW I bought it at best buy. Not open box.
