    Image retention shows up best when (A) when you've got a high-contrast image (i.e. black text on white background) open for some period of time and (B) when you use a desktop background with neutral colors OR display an application (i.e. iMovie, iPhoto), which also uses a neutral colored background, in the same area as the high-contrast image previously was located.

     

    Try this:

     

    1) Download this image (see attached).

    2) Leave high contrast image up for 10 or 15 minutes.

    3) Open up the image and move it around your screen.

     

    NOTE:
    Leave your desktop background on a nice photograph or some other image with detail.

     

    If you have IR, it will appear as if the solid gray image is slightly (or maybe not so slightly) translucent, as if you can kind of see through it. The movement just makes it much easier to see.

    A returning poweruser here, just got my LG display with 2 pixel faults and a heavy IR replaced. I wanted to wait with the procedure until I felt that there's enough pressure on Apple on behalf of the users.

     

    The service was the GRAVIS store in Berlin (Ernst-Reuter Platz), the replacement took 3 days. No yellowish color in the last 2 hours, didn't had to calibrate the screen, looked good at the first sight. However, i still did a calibration on it.

     

    As the service people told me, every replacement is now a Samsung screen, as a lot of people brought back their rMBP-s with 'burn-in' problems, so Apple decided to send only Samsung replacement parts. Also, they told me that the LG screens are which develop most of the times pixelfaults by the time using them.

     

    I'd be interested if 13' rMBP's have LG panels.

    Your display can only show 1 color at a time for each pixel, so if you have an open window on your desktop there is no other image / colors 'behind' the open window.   In other words the open windows / images you see that appear to be layered on top of something else in the backround is just a graphic 'illusion'.  When you move a window around on a backround image it is actually just redrawing itself to fill the space left where the window was, just as the moving windows is redrawing itself as you drag it around. 

     

    If your doing graphic intensive work on your computer (you mentioned video editing) then be aware that having the backround changing every 5 seconds is actually using GPU and CPU resources to change the backround which will has an impact (minimal) on the overall performance.  The drop shadow area around a window actually uses the most resources as the graphics has to calculate the 'translucent' details to draw the shadow area, to my knowledge there is no way to turn this feature off like you can in windows OS.   If you go to full scren mode then there is no issue as the backround will not try to change when there is no visible area to change.

    My 2p worth: 2 weeks ago I bought a 15" rMBP. It had a Samsung panel which was absolutely lovely until it suddenly developed 2 small groups of stuck (bright) pixels at 8 days old - 2 groups of 2 pixels (which were a bit odd in that there were tiny divots in the surface of the screen over the top of the stuck pixels, as if the pixel had physically 'blown' - and I'm certain it wasn't careless damage from me - I actually saw one as it formed). My premium reseller (Western Computer in the UK) did a prompt no-nonsense swap <14 dayfor me.

     

    Now I have an LG panel ("LPXXX") which is just as lovely and I can't detect any image persistence after leaving a grid pattern on the screen for 10 minutes.

    Exactly! Plus, the extra heat your generating may actually speed-up the onset of IR.

    I hope you never see IR, because that will be the problem has been solved. I'm not optimistic though. Please keep us updated as to the IR-free status of your screen and let us know if it changes.

    You are way off base with your rantings!  I use my machine for business and have done nothing 'special' to 'baby' it.  Every computer and profesional display we use at my company gets set up a in similar fashion.  It's just common sense.  There is ablosultely no reason to have a computer or display that is not being used to always be powered up.  As I said before ALL displays degrade over time.  No need to accelerate that process especially in a color critical industry. 

     

    I have no 'denial' about my LG screen.  It's perfect and evryone I know locally with one has had NO Issues except one person with a Samsung!  As far as Apple goes I also have no issues, their service and support has been top notch, as always.  You seem to have a phobia about future problems like your comment above about finding problems before your warranty runs out.  I use this machine for work and it has exceeded all my expectations and if any problems occur in the future I'm confident Apple will take care of them.  As a matter of fact I'm so impressed with this machine I have requested a quote from Apple (small business leasing) for 6 new rMBP's that I'm cosidering ordering for my photographers.

     

    iSheep?  Not me!  I just have no problems so I have nothing to complain about.

    Being in the photography industry, you would be even less tolerant of anything (i.e. image retention) that took away from the accuracy of your display, correct? If so, will you please keep us in the loop regarding you and your friends' rMBP machines in the event that you start seeing IR? I'm personally not convinced that Apple has fixed this issue. Nor am I convinced that the Apple I know and love is still the same with regards to quality and customer service, but I really hope to be proven wrong.

    I can assure you from my personal experience that Apple's customer service is top notch.  Not a problem there.  As far as the quality control — well that's up for debate with the IR & the wide variance in color temperature from computer to computer.

    To all people that have an LG :  can you send the first part of the serial?

    There were 22XX series 23XX and 24XX

    i had 24XX and to me IR showed only if i had 50-60%  brithness

    At full brithness IR disappeared.

    Mine is 24XX too, but I think this does not affect anything, no doubt for LG displays defect.

     

    I noticed Image Retention on my rMBP when out of the box. I tested it at first day and it failed, IR is still ongoing, and might be worse in the long run.


    If you do not see IR on any LG, you just need operate that machine some higher tempratures, for that you may need run games. And when you done, I'm sure it will shows up IR at any rate.

    High temps are not causing IR for me.  My ambient temp averages 80F.  I do multiple large batch processing tasks in Lightroom and Photoshop CS6 daily.  By large I mean importing 250-500 24MP RAW image files (10-20+GB total size) and batch processing them to convert the RAW files to DNG files > send the RAW files to an external backup drive (via Wifi) > then the following adjustments to each 24MP DNG image > Convert color profiles > Adjust white balance > Apply lens distortion and vignetting corrections >  Sharpening > Create 2048px .Jpeg preview for each image.  This processing can max out all 8 cores of my 2.7Ghz i7 for 2+ hrs.  This is shear number crunching work and photoshop even processes some of the workload with the GPU and RAM usage is up to 12GB, in addition the wifi is running full tilt sending backup copies to a remote drive.  I'm pretty sure this is a bit more demanding than running  few games on the rMBP....  Yes it runs quite warm during this workload but it's not been an issue so far, the cooling system is very efficient and the fans actually max out at first then slow down once temps stabilize, the power adapter actually gets warmer than the computer.  All this at least daily (sometimes several times a day) and still no signs of IR after 8 weeks of continuous usage.

    Jajaba, a bit of advice: just enter the lottery every now and then ( the real one ) you would be a multi billionaire with your luck.

    You know, I am genuinely surprised by your experience as I personally have tested 3 rMBPs at two different stores ( retailers ) and they all had LG displays with IR, terrible IR actually.

    I have totally lost my faith in LG dispalys as of now based on my personal hand-on experience.

    It seems you got the trouble-free LG display. Nice to read your LG display had no issues about IR. And I hope for it won't show up any sign of slight IR.
