i just received my MacBook Pro Retina 15" 2.8 GHz today, it's a LG screen version SJA2.
I made the checkerboard test with 5, 10 and 15 minutes. No signs of IR or ghosting at all (knock on wood). Maybe it really has something to do with the SJA2. I'll update this post if i will notice signs of IR or ghosting.
My laptop came back. screen was replaced with Samsung:
But I have a problem - I took it to other MacBook Pro Retina laptops they had on a display and when comparing colours and contrast my laptop screen is like all yellowish with lower brightness and I would say contrast. All three guys who work there agreed the colours are not great - I was in mountains working on time-lapse film so I have a lot of photos with snow. I copied few on USB memory stick to check them on my screen and one of theirs. Snow is not white, it's greyish-yellowish. They said I could leave my laptop and they can send it back or I can go to bigger Apple store where they have service. So 6 working days in repair and now I have to take another day off and go to see them at store that is almost hundred miles away. Apart from screen all works just fine. The dissapointment is huge.
@muriss, RE -- blue screen at startup
I was on the phone with Applecare for an hour and was then moved up to a second-tier advisor for half an hour. What finally seemed to solve it was removing a "desktop playlist" file from the Preferences folder. Now, there is more than one desktop playlist file in the Preferences folder, and if you remove the wrong one I'm not sure what would happen. It's supposed to "refresh," I was told, upon each start up and install whatever desktop image you selected prior to last shutdown. Mine wouldn't refresh and was caught up in some kind of forced override, constantly installing "Aqua Marine Blue" solid color desktop -- which isn't even one of the Apple solid color choices. Bizarre.
My recommendation to you: call Applecare and have them walk through this with you. You will have a record of it if it ever happens again, and you'll be certain not to do something in the preferences folder that you'd wish you didn't.
Also, musiss -- is your machine a CTO? And what city was yours delivered to. I ask because, when I was on the phone with the first Applecare rep (a nice enough guy, but kept me feeling he was randomly guessing half the time) he said "many in your area" have experienced this problem, like it was region localized. I had my 2.4ghz/8Gram/512SSD configured and delivered to the Apple Las Vegas Forum Shops store. Just curious.
We calibrate all our rMBP's to the same target values of 65K, 2.2 gamma and we make 3 different icc profiles for brightness levels of 90cd, 160cd & 240cd. While the Xrite calibration process automatically adjusts the rMBP to a target brightness during calibration it does not set the displays brightness when you select / change profiles. In other words when you change the brightness levels on the rMBP you are varying the percieved colors on the screen as the profile is only accurate for the brightness it was calibrated at. The brightness control on the rMBP cannot be set to an exact level without a sensor so we devised rough settings based on the number of 'bars' shown on the brightness level popup. On average 9 'bars' = 90cd, 12 = 160cd and 14 = 240cd. So when editing in the field we can set the profile and brightness for varying ambient light levels for basic editing. The brightness levels on each machine vary by +/- 10cd or so but it seems to give us a fairly consistent baseline for final calibration on our high gamut RGB monitors. We also only use RAW files and edit in Lightroom in the field so it's easy enough to fine tune any variables in final editing.
The Samsung display has a higher black level (not as dark) as the LG's, this is where the difference in contrast comes from, not in how bright the display gets. I actually have not really looked at the maximum brightness levels between the two, they are way to bright for photo editing. Our replacement for the Samsung with dead pixels is due in tomorrow, if it's another Samsung I'll check the max brightness after calibration. For reference the calibrated LG rMBP I'm using measures a max brightness of 338cd and the whitepoint shifts to 6572K from 6504 @ 160cd.
FYI: If you are editing any images for high end printing you should make (and use) a calibration for 80 - 90cd brightness set at 80-90cd brightness levels, if you use your 120cd calibration @ 120cd brightness level you'll find that your print output will be much darker than what you see on your screen.
Got my Macbook Pro Retina 15,4" (CTO: 2,4 GHz, 16gb RAM, 251GB Flash Storage) today. I also got the new LG Display (LP154WT1-SJA2), so far there isnt any display-burn-in/ghosting (checked it several times). By the way I didnt experience any fan issues either.
Greetings from Vienna (Austria =! Australia)
Just another data point:
Bought my rMBP 2/16/13. Mid-2012 2.7/16/768. As far as I can tell, trying the IR test with different combinations of windows on the dark gray desktop shows no sign of IR. No color cast, or uneven lighting.
LG - model LP154WT1-SJA1
Build Week 46, November
I'm very picky. My background as an engineer, semi-pro photographer, and graphic designer gives me the experience (IMO, anyway) to find these types of flaws (unfortunately, I also find those that wouldn't bother other people...). I've owned many PBs and MBPs, and this display really is the "next level" (1998 Wallstreet 14", 2001 TiBook, 2003 TiBook, 2005 17", 2006 C2D 17", and 2009 UB 17").
HELP ME DECIDE please.
My LG screen was replaced due to image retention. Replaced with Samsung screen but I don't like the colors, brightness and contrast. I took it to Apple Store again and they agreed with me and replaced it with another Samsung screen - same thing, brightness is better but white balance is wrong, epsecially when comparing to MBP with LG screens that they have in store. I was suggested that I can call Apple and request new laptop but should I? LG screens have problem but look way better. Should I request a new laptop with LG screen and ask for newest release hoping the problem is now fixed with their screens?
What would you do? I love my laptop but knowing that screen can look better this love faded a little bit. I paid for quality - it's unbeleievable when you see the difference between LG and Samsung screen. Even Apple Store manager, who was really nice, agreed with me.
Buy a calibration device like a colormunki. That should fix your Samsung display right off. Beware though - many people are so used to seeing displays that are too blue. When you actually see a correctly calibrated one it may appear yellow. Just give it some time and you'll never go back to a non-calibrated display again.
I never used one but I can do it. The only problem is - it costs money and should it really be me paying for calibration. Seriously - they advertise this laptop as a tool for professionals even saying " In fact, it has a 29 per cent higher contrast ratio than a standard MacBook Pro display. Blacks are blacker. Whites are whiter." In case of my laptop this is not true - Apple Store Manager asked me to open just empty word document and she did the same on standard MacBook next to it (no Retina) and she was surprised how yellow mine was!
Most people are used to very blue displays. The Samsung is indeed slightly yellower than the LG, but properly calibrated screens are slightly yellower than the way most screens usually are at factory settings.
I did find the colours on the Samsung to be slightly worse, but I'd take this over image retention any day, and it is still significantly better than any other computer screen I've used.
It is annoying, though, that we can't just get one screen which has all these positive qualities.
Professionals always pay for calibration. You probably won't find a photographer out there that does not have a calibration device despite whatever computer they have. So not calibrated from the factory is not something most pros would care about because they would always be calibrating anyway.
That being said, I suspect that from the factory these Apple laptops are calibrated to a certain extent. I have a theory that when they replace the screens, they don't re-calibrate them. So it could be very possible that a newly installed Samusung screen is much worse than one that comes from the factory like that. If that's the case, you do have a point - had you received it out of the box with a Samsung, it might have been more properly calibrated.
All of this problems related to the RMBP screen are from the old retina model? Does the new models, refreshed about a month ago, have those same problems?
And how can I know if the RMBP I am buying has a good quality screen (i.e. no screen problems embedded)?!
I'm asking that because i'm willing to buy one RMBP 13" in April...
