    Yes I can.  Week 48 LG, no problems at all.  It's in use about 6 hrs daily mainly for pro photo editing and some basic business use.  I also know 5 other local owners who are graphic/web designers or photographers 4 have LG screens with no issues and the 5th has a Samsung that he just returned due to inability of calibrating an accurate white point.  All of these are original delivery rMBP, no returns or replacements (except the Samsung).

    I can. I have had my rMBP for almost a month and have experienced no real use image retention. My display is an LG and the colors are very rich and accurate.

    How do you tell what week the display was produced. I know of websites such as chipmunk and appleserialnumberinfo but I don't trust putting my serial number into them.

    No defect of any kind to date on my 15" rMBP / 2.7GHz  / 16GB / 784GB / Production Week 41 with LG screen bought Nov 18th 2012. I've used it extensively every day the "normal way" for me (doing a bit of everything: web, photos, videos, read/write texts, etc.)

     

    However, whether this will prove to be useful or not in the long run, I've been taking some precautions to avoid or delay IR in case my screen is "doomed" to have it eventually. Please people (you know who you are) refrain from repeating again that you are certain that ALL the LG screens are or will be defective).

     

    As to the precautions, I've been using a screensaver to come on after 5 mn for when I leave my desk. Also, I use a few series of background images, including Apple's solid colour set, which change randomly every 5 sec. I've increased the solid colour set to 40 picked from the web.

     

    When working with multiple windows open or full screen you very soon don't notice the rapid changes.

    You don't really have to worry. There's no requirement to provide any other personal info on the site.

    Why do you use a screensaver / solid color sets?  It's much easier to just set the display to sleep after inactivity for a set period of time.  I use 2 minutes for battery power and 4 minutes when plugged in.  I originally set the computer to sleep after 1 hour when plugged in thinking it would restart quicker if not in sleep mode but I found it starts from sleep mode just as quickly by setting the sleep to the same timing as the display off.  I just tap the trackpad or space bar to wake it, with the SSD and OS X in 2-3 seconds I'm good to go (and connected to wifi).... This saves running time on the display, the backlighting, GPU, CPU and saves on your power bill as well.  Another easier option is to just close the lid, all your windows / work will reappear just as they were when you reopen the computer.  Over the long haul either one of these options is better than leaving the screen on when your not using the computer, likely the backlighting wiould be the first thing that starts degrading with more hours of running time.

    Hmmm I thought since LEDs are now used for backlighting it wasn't supposed to degrade like CCFL backlighting.  On my retina MacBook Pro when the slider is set to "Never" on display sleep, it no longer has the language, "never letting your display go to sleep may shorten its life."  This language appears on my 2009 MacBook Pro.  Both are running the latest version of Mountain Lion.  And both use LED backlighting.

    Jajaba Level 1 Level 1 (0 points)

    LED's are more stable and don't degrade the same way as CCFL's but in there own way they still degrade over time.  The most common 'failure' is gradual loss of light output and loss of efficincy.  This means they will run warmer and degrade faster as they become less efficient.  There are other issues in applications like notebook backlighting; the LED's are mounted around the perimeter and light the display through a diffuser / reflector 'panel', the actual light coming from the diode never really directly hits the display.  All the 'light piping' and diffuser materials are made of translucent plastic which will eventually also degrade over time due to high temperatures (think of yellowing / brittle old clear plexiglass).  The LED's used in notebook backlights are in the 'super bright' catagory which means they run very hot, again compounding gradual degradation over time.... 

     

    Don't worry this is a slow process, but the more heat the LED's and plastic have to disipate the faster they will degrade and at some point the backlight will dim enough to be noticable and eventually they will not be able to maintain a correct whitepoint even with calibraton.  Just turn the screen to max brightness for 10-15 minutes and feel how warm the back of the display gets....  That's why I choose to have the display turn off and the computer go to sleep when I'm not using the computer, as well as the power savings.  Just thought of another reason, the fans, I bet they also are spinning if a screen saver is in use which would also shorten their lifespan and needlessly suck more dust into the computer.

    MICLAR1-  I just reread read your post about using solid color backrounds and realized that your chaging the desktop backround colors while actually using the computer (I think?).  If that's the case you may want to reconsider as that will do nothing to prevent IR.  The changing solid colors will only show on any visible areas of the desktop on your screen, It doesn't change the colors behind an open window which is where the IR would be generated from so it's not going help to prevent IR....

    New Mac user here. Ordered a custom built rMBP 15, 2.6/16/256 on the 9th January 2013. It has an LG screen and after doing the checkerboard IR test for 10 minutes it definitely has some IR, albeit only minor.

     

    I'll see about contacting the support and see what they say about it should it get any worse.

    No problem for me. i bought my custom built rMBP 15,2.7/16/512 on August 2012 it has LG screen and the screen is wonderfull : no ghosting, no clouding and no dead pixels : for the moment

    you can see how much imperfect are this kind of monitor...

    100 euro monitor haven't this kind of problem... really ridiculus

    To JAJABA - Concerning the screensaver versus sleep we concur along the main points you mentioned. My computer is plugged in 90% of the time. My full settings were: screensaver 5 mn;  display sleep 10 mn: computer sleep 15 mn of inactivity. These would take care of my short absences from my desk as well as long video conversions done mostly during the night. Thanks for the tip of using the same timing for computer sleep and display off.

     

    Concerning the 5 sec desktop backround changes, which I've been using while actually working, you're most likely right. I'm no computer expert and had assumed that would help somehow. I came to that conclusion while watching a series of abstract painting backgrounds which I've used in the same manner. When one of these images with a bright contrasting color line is showned, that bright detail appears lightly into the next image but fades out in a millisecond.

     

    Still, I would be curious to hear from someone having the IR problem who would try this to learn if it improves the experience.

    If you think you've got a flawless LG, great. I honestly hope you do. However, please, for your own sake, just use your rMBP normally like you would any other laptop, without any special treatment. Trying to prolong the onset of IR is silly and illogical. If your machine is going to get IR, wouldn't you want to get it soon, while you're still in warranty? How are you going to feel if you baby your machine and then, a day after your warranty expires, you start seeing image retention?

    This is insane! It's a $2000+ (USD) computer! You should not have to do anything special. Why do you guys insist on babying your machines? It's a Mac! If you need to baby it then there's something wrong with it. Why can't you see or admit that? The denial I'm seeing from the LG owners is sad. You're the reason that Apple hasn't fixed this problem yet. You're too willing to accept what is clearly subpar performance in a premium product. Stop being iSheep and use your voice to get the machine you paid for.
