    Replacement came in and it still has the screen retention problem.

    I looked at my screen and I have an LG screen...

    For those who don't have the issue which type of a screen do you have?

    A00E= Samsung
    A00F= LG

    Also if you have gone through replacements how many did it take? It sucks because for the second time I had no issues with anything else other than this.

    And if you wanna be super sure about your display make...

    You do realize, ghosting is due to insufficient GPU capabilities? Apple really screwed this one up by using such pathetic GPU.

    Got a replacement about a week ago and I do see ghosting. Mine is LG. Getting a replacement as soon as they have some in stock.

    I don't understand, if the problem is due to insufficient GPU capabilities, then why isnt every single screen on every single unit that has this GPU ghosting? every single machine has the same GPU, or am I missing something that you are trying to say?

    Not every GPU is always created alike. Due to the binning process and all, each individual GPU will vary. Of coarse, same branded parts will have similar performance levels (in this case GPUs branded as the GT 650M). However, if the part came out as a good batch, but was binned down during fab to make it into a GT 650M, then it will perform marginally better than other defective binned down parts. This makes a bit of difference. In terms of performance, it can mean the difference between ghosting or not.

    However, there is also the screen side to take into account. Response time is important as well. Having it under 5ms guarantees no ghosting due to screen faults.

    However, which side is the one at fault here? Tough to say, but my bet would be both sides equally.

    I've had 4 RMBPs so far, first 2 were Samsungs with a slightly pink tint, and my last 2 have been LGs with yellow tints and dimness. I would rather just have Apple replace the screen so I don't have to keep starting fresh. Surely there has to be a way for Apple to identify whether a part is the Samsung or LG LCD? At this point I would rather have a slightly pink Samsung display just because it's brighter.

    May I enquire as to why you've been through four? Screen colours? Do apple just replace it?

    Sorry, but no. The "ghosting" or "image retention" problem has nothing to do with the GPU.

    Yeah ... that's not how it works.

    Perhaps we should try to pin down what the original poster means when he uses the word 'ghosting'.

    Does the screen have clear output lag when moving the mouse cursor or a Finder window around?

    The retina display is marketed as an IPS display, but the thing is, Samsung doesn't make IPS displays per se. They make displays based off an IPS derivative they call PLS. Maybe that could explain it? The LG displays are IPS and the Samsung displays are PLS.

    That would explain the relative dimness you guys are seeing in the LG displays, PLS panels are supposed to be around 10% brighter.

    Well the first one I bought had a pinkish tint. Looking back at it, I'm questioning whether it was actually tinted or if I was just seeing things. So I exchanged it for another one (Best Buy, not Apple), that had the same tint. These were both base models. Then I decided that I wanted a 2.3/16/256, so I ordered one from a reseller that had some in stock and returned my pink base model. The one that I got from the reseller was pretty bad, and noticeable. It was quite dimmer compared to my last one (I did a side by side comparison before returning my pink base model) and obviously yellow. I bought one from Apple and sent my other one back. Now this one from Apple has the same issue.

    My 1st rMBP had bad ghosting - it was an LG.

    The 3 replacements were all Samsung, and while they had no ghosting they all suffered from varying levels of backlight bleed. (Whereas the LG had almost none). I preferred the picture quality of LG for the most part, but the ghosting was unacceptable.

    tried entering that into the shell to check my screen and got nothing back. Is ML not allowing it?

    I was wondering about this. As far as I knew, Samsung only manufactured PLS and MVA/PVA panels, and all IPS panels are currently manufactured my LG.

    Has anyone looked at a Samsung model under a microscope? I would if I had a Samsung model

    I have the LG screen. No ghosting. Plenty bright. I run the screen at 75 % brightness.

    I suppose it is possible that Samsung licensed the IPS manufacturing process so that they could be counted as a supplier for the Retina screens.

    But to my knowledge, nobody has been able to conclusively prove that the "LSN" part # prefix means that the manufacturer is Samsung. Their other (TN) displays being used inside other models of Apple laptop start with "LTH". I have been able to find plenty of Samsung LCD panel part numbers that start with LTH, but I have yet to find any examples of Samsung panel part numbers that begin with LSN. So all we really know for sure is that the Retina part # that starts with LSN isn't LG.

    There are Macbook Air screens that start with LSN that are typically sold as Samsung panels, e.g. LSN133BT01-A01
