MacBook Pro Retina display burn-in?

As having had an LG panel with the IR issue and now a replacement Samsung I got through the "lottery" of exchange shows a significantly better contrast. I know what you mean by the "pinkish white" on the LG, and first thought it was just my bad eye sight hah. The whites are reasonably "whiter" than the LG, but ultimately the significant contrast difference between the two panels is what caught my eyes (Richer dark colors, and still able to distinguish texture -- it was a little more difficult to see in comparison to the LG). My LG was an early week 23 unit, and my new samsung is a week 32.

I had sumsung display but cosmetic problems with my rMBP so I went and replaced my. I got LG week 32 with ML preinstalled. I first i did ghost test in recovery and it was there, strange that i dont have any in actual os.

Then i set dark gray and safari page full brightness waited for 5 mins and nothing. Then for 10 mins and nothing. In 3 hours i did it 3 time for 15 mins nothing at all. So is it safe for me to say that i got no IR?

I dont even use dark gray as a defualt backgroud so I think i am one of the few here that has a normal LG screen or no?

Also after having sumsung first i kinda consider blacks to be better here but maybe its just me...

In the end i am also pretty sure i have less scrolling lag on this machine then i did with the sumsung one but maybe that because i didnt install everything yet but for now it looks as scrolling is better.

Just to make sure I understand the Apple policy on this...if I order a rMBP, take it out of the box, see right away that it's an LG, and immediately return it to an Apple Store, they'll accept it without any question or reason? I've been through the process of replacing FOUR iPhone 4S's (and still have a bad one), and I'll never do it again. I'll give Apple one chance before taking my money elsewhere.

NO questions asked... just return it. My replacement MBA (first two displays were dismal) is on it's way. I can't wait to see what they shipped me this time.

BTW.. I got ripped by two users on the MBA thread for posting that I was having an issue with my Air's screen. https://discussions.apple.com/thread/4119502?tstart=0 Unforunately, most Air users don't seem to care about the quality of their screen.

Interesting observations. Yeah who uses default gray as a background anyway, reminds me of the mac desktops decades ago. Whats not discussed here is that both LG and Samsung use different screen types.

LG is a AH-ISP panel, while the Samsung is of a different variety called PLS. The newest laptops using LG LP154WT1-SJA1 display seems to be getting good comments online versus Samsung LSN154YL01001.

PLS is a slightly different technology then IPS and seems to manage fast motion quite well. I have the samsung 850 which is a 27 PLS and it is a fabulous monitor.

Hey, i double cheked and yes i do have LP154WT1-SJA1 and so far IR FREE!

Is that a different part number from LG vs. some of the earlier LG part numbers?

I am not sure. Look for laptops with ML Preinstalled i think they are good. Because i bought my first laptop on monday and it had Lion. Just yesterday i came to the same store asked for another one and got one newer with ML preisntalled.

I think it even works faster overall.. but i may be wrong.

I would be very (happily) surprised to see a new model number from LG in response to this issue

I think you are correct. I have the LG screen with the same part number and ALSO with ML preinstalled. All other rMPR had Lion on them. So far no IR issues. Might be a fixed model.

@Fiercy2.

I jumped back to this thread because I noticed LP154WT1-SJA1

I have that same model screen. In normal use it has no noticeable IR. But do that checkerboard test for 20 minutes and it has IR. Might be faint and dissapear quickly but its definitely there.

Hey my Custom rMBP was shipped on 1st aug and I will be seeing it for the first time tomorrow as I have been away.

This discussion is getting huge and its the first time that I have seen I and my heart has sunk a little!

From what I can see from going through the 75+ pages ! the LG may have problems that could manifest in different ways and extents. But the Samsung seem to be good to go?

How do i tell whether it is an LG or Samsung screen?

Sorry if this has been covered elsewhere but i really cant find the answer easily!

Cheers
