I got a 2nd gen (late 2013) macbook pro with retina display (15'inch, high end) at an apple store in Tokyo. It comes with a Samsung Display. After 3 weeks a stupid friend made a very serious scratch on the screen by her findernails, and I replaced the screen at the apple store. However after 5 days of waiting I found that they replaced me a LG display, the model is: Color LCD LP154WT1-SJE1 DCN334601F9FF0NB1 I started searching the website to see if there are someone who has already got the "ghost image" problems with this specific type of display, I also did a IR test at the website, shows no IRs, so far. But if the screen will be having the ghost image eventually (say, 1 month or longer), I have to find another excuse to get my mac repaired and ask them for a Samsung display, Because this is really annoying! I have a 1st gen macbook pro retina version and the ghost-image is too bad! So please help me if your screen is exactlly the same with mine and whether you have suffered the IR issue, and please dont forget to tell when did you purchased it, or if anyone who can tell me that has LG really solved the IR issues or not in 2013. Thanks, all the best.
