    Is there someone who is lucky to receive a Samsung panel with the standard configuration 2.3 / 8GB / 256 ?

  • my-username-was-taken Level 1 Level 1

    To the person posting about waiting to get the rMBP (and anyone else watching here and debating). WAIT. There's not just the screen issue which is very very common but if you've Google'd a bit, you'll see people talking about decreased battery life with Mountain Lion among other bugs with it. I have not yet upgraded to Mountain Lion but honestly if I was talking to a friend...I'd suggest they wait til, in the very least, they fix their screen issue and then upgrade to Mountain Lion later as well.

     

    This is a gorgeous machine...But there's just too much wrong with it. Aside from the burn-in, I also get artifacts that don't disappear on my screen and I need to change the resolution back and forth to fix that (after sleep). I'm told that is fixed in Mountain Lion and who knows if that has anything to do with the ghosting...But again, if you want an rMBP I'd seriously wait. This IS super frustrating as you could imagine.

    I am a new Mac user (will depend on how my retina experience goes, if I stay).     The terminal used to determine the maker of the LCD display. I assume that is like windows command prompt?     Where can I find the terminal once I get my MacBook?

    Have you used gfxCardStatus?   (decreased battery life)

  • mick jones Level 1 Level 1

    I have to to strike a blow for the rMBP. I got my probs with the lg too, yes, but now with a sammy display its just perfect. For the people, that are unsure if you should buy one: Its really by far the best Notebook I ever got and this is my 3rd Apple Notebook and I have experienced a lot of others. Battery Life is great, ML ist great (much better than Lion) Please don't bash too hard on this one. *Just my 2 cents*

  • RetinaUser Level 1 Level 1

    These are my first result with the test application:

    Persistent image time: 14:59
    Ghost persistence time: 07:13
    Used gray tone: 95
    Display brightness: 100
    Used pattern: Chessboard
    Result code: T11459T2713P1G5fB100I0

     

    The chessboard took about 7 minutes to disappear... quite impressive. I want to know how much time took a persistent image to disappear on other LG's display, just to understand if the behavior of my LG display is normal compared to the others.

    My retina works very well except for the display. Since i am almost sure that if i change it with a new one it will be another LG, i'm trying to realize if it will be more likely better or worse than the one i own.

  • my-v Level 1 Level 1

    Hi guys, received my MBPr with LG Display and slight IR. In fact, you only notice on a grey background and it doesn't disturb my "normal" work, but I will watch this problem.

     

    Could the MBPr owners who have display problems please run the Apple Hardware Test (press "D" while restarting)? I'm excited to get your results!

  • Ronald Burgundy Level 1 Level 1

    Base model here, week 33. LG (LP154WT1-SJA1). Absolutely no noticeable IR the first day even under scrutiny, but by the second day it was starting to appear. 4 days in, it's significantly worse. If you think you got a good LG display, I suggest leaving it on as much as possible for the first few days to accelerate the process. Otherwise, you may notice after your 14 day window has expired, and they could give you the run-around.

     

    Has anyone identified a pattern as to build weeks and which displays are associated? I would be surprised if the panels are truly random off the assembly line, but I don't know anything about the assembly process.

     

    It's too bad that Apple and Samsung are not getting along better. Combined, they make good products. LG panels have a lower cost across the board, and the quality difference shown in the pictures in this thread is consistent with the quality difference long been seen between LG and Samsung televisions. LG is budget tier, so it's disappointing to get one in a premium product, especially when paying the same price as Samsung screens.

     

    I'm going to swap this one, and although I'd definitely prefer a Samsung, I'll take an LG with no IR. However it's becoming obvious that all of the LGs suffer from this problem under scrutiny, and with it getting progressively worse within the first several days, I don't want to chance it turning bad in a year. I'm convinced anyone claiming to have a good LG either hasn't let it run long enough, or doesn't have a discerning eye.

  • tivoboy Level 1 Level 1

    Honestly, I'm really torn

     

    Have a 2.6/16/256GB which is the best config for me.  I've had it about 12 days, but only been able to spend about 2-3 days with it.  It's the LG screen.

     

    While there doesn't APPEAR to be an IR issue, I've tried the tests, etc, the issue that I DO have is that it seems as if the brightness doesn't go to 11.  I mean, compared to my 2008 MBP, it seems as if there is about 2 clicks of brightness missing.  I've changed the settings in Display and Energy saver to make sure I'm not capping it somehow, but still in a normally lit room I have to be at about ONE CLICK below full to have a comfortable viewing brightness.  Is that normal, for the LG but is the Samsung brighter?

     

    But I'm torn, since pretty much everything else about the machine seems perfect. No dead pixels, everything just ROCKS, burn in doesn't seem to be an issue - although I've only put about 3-5 hours use on the machine. 

     

    I only have till Monday (it arrived on a monday about two weeks ago) to return it if i want, and even then I probably have to do it Sunday due to work)

     

    I'm leaning to just returning it at the moment, waiting it out and ordering another one in a few weeks.  Although, will Samsung continue to supply at the same rate as they have with these stupid law suits?  I think we know now that LG will be supplying the new iphone 5 screen or at least that is the talk on the street.

     

    Thoughts?  Live with it, or send it back and live to fight another day?  Is there any way to tell if the brightness on THIS machine is equal to what the Samsung WOULD be?

    LG is now a major producer of high resolution displays, not budget tier.  They are not anything close to their roots as Goldstar.   They are now producing very cutting edge 4K displays for sale even before Samsung gets their act together.  see  http://www.engadget.com/2012/08/22/lg-4k-84-inch-uhdtv/

     

    IMHO this discussion about LG AH-ISP panels being inferior to Samsung PLS (variant of ISP) offers little proof that the problem is widespread, yes obviously there are some bad panels out there.

     

    As one person observed in Macumors.com: Reading posts on here as well as on Apple forum (over 105 pages) kinda makes your go crazy in thinking that something better is out there, when some say you must exchange until you get samsung and other saying there is no difference.

    I ran the 15 min test twice both normal and inverted that RetinaUser supplied, nada IR for my LG based panel (LP154WT1-SJA1).   My laptop is more then couple of weeks old.

    When one pays for $2200 to $4000 for a laptop, it better be functionally perfect. Who knows what other flaws this LG panel may exhibit down the line when the machine is out of warranty?

     

    The amount of people who have seen 3+ panels with this flaw makes me believe this is not a QC, but a design problem.

     

    As evidenced by the Macrumors poll, it appears 50% of panels are LG and 50% of those panels have IR problems. This is not a QC issue, LG would be losing mad moneys to create so many LCDs with flaws knowingly if their QC is working properly.

     

    The question is if LG and/or Apple engineers knew about this IR problem before they released the panel. It's hard to imagine what respectable electronics engineer wouldn't test multiple copies of their product for 2-3 weeks before releasing it to the public, and IR surely should have shown up by then, so I'm inclined to believe that they knew about it but released it anyways hoping people wouldn't notice.

     

    Of course the Macrumors poll doesn't specify how long to use the panel before testing IR (some brand new panels apparently do not exhibit IR) so the defect rate maybe even higher than that poll indicates.

     

    It seems Apple doesn't ever do recalls unless forced to by class actions (Original Magsafe adapter, 8600MGT), so I hope some lawyer is reading this thread and gets us all free rMBP upgrades (or something like that, I have wasted over 6 hours talking to Apple on this issue alone and still haven't recieved a replacement panel)

  • zonly1 Level 1 Level 1

    I just got my week 28 rMBP from apple after having my LG with terrible IR replaced. The replacement was also LG but no IR what so ever. I tested it for a couple of hours now and nothing.

     

    So not all LG screens suffer from IR. At least it looks like LG might have fixed their panels. If IR crops back I will update here.

  • johns1 Level 1 Level 1

    AppleCare covers you for 3 years.  The bit about what flaws will appear after a great deal of time is fluff, problems usually appear fairly soon in a products life.   It not like one's computer screen exhibits problems a lot.  I seen hundreds of LCD panels and displays, very unusual to run into noticable IR.  Beleive or not I even seen permanent persistant where the image no longer disappears on a LCD display, quite rare, but happens sometimes.

     

    The macrumors thread The Ultimate rMBP Image Retention Test which includes a poll represents 154 votes only, hardly enough inputs to statically project a accurate representation of the true number of panels with issues.   If Apple ships thousands of MBPr's and all we see is that, drop in the bucket.

     

    I threw out another macrumors thread Any rMBP owners here with a flawless LG screen? which now has 84 posts.

     

    If someone would count the number of people that actually posted in this thread that had a IR issue that they would like Apple to correct or has been since repaired/swapped out, your probably looking at something between 100 to 200 legit failures that I would certainly hope Apple went out of its way to correct without the customer having to argue his/her position.  

     

    BTW don't spin that 2k to 4k bit, as Mac's have always been expensive and todays Mac's are way cheaper then they use to be.  I agree no one that spends a good chunk of change should encounter problems, but stuff happens. 

  • my-username-was-taken Level 1 Level 1

    I have ghosting and I do not have a user account on mac rumors forum. nor do I particuarly intend to get one... i wouldn't go by that forum or its survey. i would go by this official one. and i'm apple does do.

     

    and yes i'm sure LG has fixed their panels by now if not already -- but there's a huge number of panels out in  circulation that are bad and they should be able to put a date on them based on all the reports. they should issue a recall for screens before that date. and should create a very simple application that lets the user run it to see if they are eligible...it would be very simple and responsible of apple. especially on this flagship display.
