Longevity Burn-In Test
Updates And Results From 100 TVs

Updated
Sony A90K with bad image retentionSony A90K OLED with bad temporary image retention.

Our accelerated longevity test has been running for over a year now, and from full-on panel failures to image retention and LCD degradation, we've already encountered some interesting results. You can learn more about our latest results with our RTINGS.com R&D videos or our ten-month update article.

At the bottom of this page, you can see the raw data for all TVs on this test below by selecting the month and uniformity slide you'd like to see. If you want to learn more about how we created this test, check out our first article here.

This is an ongoing test on 100 TVs, and we'll provide updates as events occur throughout the test. You can check back on this page for the latest information, or subscribe to our mailing list to be the first to know.

Year 2:

  • Dark spots on the Hisense H8G
    05/02/2024: The 16-month results have been uploaded to each individual review. The Samsung AU8000 is still broken and has been temporarily removed from the test. We're monitoring several issues with almost all TVs, including uniformity issues and significant backlight failures on some LCD models. The Hisense U8H has lost nearly 70% of its brightness since the beginning, and the Hisense H8G has developed dark spots across the screen over the last two months. There's no significant change to the OLEDs; the Samsung S95C OLED remains surprisingly resilient, with no noticeable signs of burn-in, but every other OLED is showing some image retention.
  • 03/27/2024: The backlight on the Samsung AU8000 has failed. We don't know yet if we can repair it, but we're looking into it to determine the cause of the failure and if we can fix it or not.
  • The backlight on the Hisense U8H is failing
    02/13/2024: The results after 14 months have been posted to each review, and we've updated the table below. Not much has changed over the last two months, with no new full failures. A number of LED TVs are continuing to show noticeable degradation. The Samsung Q900TS 8k QLED has a more noticeable dark spot along the bottom middle of the screen, and the backlight of the Samsung AU8000 is continuing to fail. There's a pinched spot on the bottom of the LG QNED80 2022; this appears to be physical damage on the outside of the TV, not a failure of the panel. The backlight on the Hisense U8H (right) is failing rapidly; at this point, it's pretty much unusable. As for the OLEDs, well, they're continuing to experience burn-in, especially the older models like the Sony A80J OLED and the LG CX OLED, and the Vizio OLED 2020 is nearly unusable at this point.
  • 01/25/2024: We've posted our latest video, covering the 1-year results with a focus on LCD models and future failures. Check it out here!
  • 12/20/2023: We've temporarily paused the longevity test during the holiday break. All TVs have been fully powered down and will be turned back on following our normal schedule on January 3rd, 2024.

Year 1:

  • That's no moon! That's the uniformity issues on the LG NANO90 2021!
    12/05/2023: We've posted the 1-year results to each review and updated the table below. Most of the TVs on this test have now accumulated 7,200 hours of runtime. Not much has changed since our last update. The same LCD TVs continue to degrade, and some are so bad that they're unwatchable. The Hisense U8H, which started to show some uniformity issues in our last update, is now completely blue in the center of the screen, and the Samsung TU8000 looks terrible. Over a dozen LCD TVs are now showing signs of image retention, but only on a 5% gray slide (TCL 6 Series/R646 2021 QLEDLG NANO75 2022Samsung Q60B QLED). This isn't noticeable with our published slides or real content. This might be caused by some form of TFT voltage shift, similar to temporary image retention on an OLED, but LCD TVs lack the compensation mechanism necessary to remove it. We'll keep monitoring this issue to see if it worsens. As for the plethora of OLED TVs on this test, most are also showing signs of burn-in now. Interestingly, the Samsung S95C OLED, which uses a new real-time compensation algorithm, looks significantly better than the Samsung S95B OLED after the same number of months. As for the three monitors, the CNN breaking news bar is barely visible on all three of them, but only on test slides; it's not noticeable with real content.
  • 10/17/2023: We've posted a new article exploring the main events over the last ten months and what we've learned so far about longevity. You can read more about our latest findings here.
  • 10/11/2023: We've posted the ten-month results to each review and updated the table below. It's been a fairly quiet two months, with no new full failures, but LCD degradation on some TVs is getting really bad. Some TVs, like the Insignia F50 QLED, could be considered to have failed, as it's unlikely anyone with a TV that looks that bad at home would continue to use it. However, we'll continue testing them to complete failure to see just how bad it gets. There's also a noticeable improvement in some of our OLED TVs, as we recently discovered that some TVs weren't running their short compensation cycles properly, or even at all in some cases. We're now forcing this process manually before we take our uniformity photos, and on some TVs, this has cleared up the image retention considerably. To learn more about this change and our findings, check out our latest RTINGS.com R&D video linked above.
  • 08/10/2023: Unfortunately, after posting our eight-month results, we noticed that there were specks of dust on our camera or lens when the photos were taken. This doesn't impact the overall results of the test, but these specks are noticeable in the uniformity slides for each TV and monitor. We've updated our methodology to ensure that this doesn't happen again.
  • 08/09/2023: We've posted the eight-month results to each review and updated the results below. Most TVs continue to perform well, but there are a few TVs that are getting worse. The Insignia F50 QLED looks terrible, with a significant portion of the screen darker than the rest, and the backlight of the Samsung TU8000 is getting worse. The dead column on the LG G2 OLED is back, and there are other dead columns. The Sony A90J OLED and the Sony A90K OLED are both significantly brighter than they were at the six-month update, and we don't know why. Finally, the TCL 6 Series/R646 2021 QLED shows signs of temporary image retention in a surprising development. It's different from OLED burn-in, and we'll look into this to better understand the issue. The results for the monitors on the test have also been updated.
  • 07/04/2023: After running ~500 short compensation cycles on the Sony WOLED TVs, we've managed to eliminate a large amount of image retention from some of these TVs, which implies that it was temporary image retention and not permanent burn-in. Some burn-in is still visible. The vast majority of the reduction in image retention occurred in the first few cycles, but we still ran them to match the Sony TVs to the LGs. Except for the new models recently added, all TVs have run approximately the same number of compensation cycles since the beginning of the test. Since CNN updated their logo on June 1st, we've also been looking into how this impacts our longevity test.
  • 06/09/2023: We're looking into the short compensation cycle on Sony WOLED TVs to better understand them. We've found a way to manually trigger this cycle, so we're running it repeatedly so that Sony and LG TVs will have run the same number of compensation cycles total since the start of the test. We hope to have the results of this test in the coming weeks.
  • 06/07/2023: We've posted the six-month results to each review and updated the results below. The uniformity issues with some LED TVs, like the Amazon Fire TV Omni Series, the Insignia F50 QLED, LG NANO90 2021, and the Samsung AU8000, continue to worsen, and we see more signs of burn-in on most of the OLED TVs. We'll post another article to explore these issues and share our findings with you in the coming days. We've also added the initial measurements for the LG G3 OLED, which has now been added to the test.
  • 05/24/2023: The motherboard of our LG 27GR95QE-B was swapped out with one from a new unit, and the monitor is working again and has been returned to the longevity test.
  • 05/23/2023: We've replaced the mainboard for the Samsung QN900A 8k QLED, and it's working again. We've added it back to the test.
  • 05/18/2023: While trying to enter the service menu, our LG 27GR95QE-B shut down and no longer turns on. It appears to be completely bricked, so it's been removed from the test.
  • 05/11/2023: Unfortunately, after partially disassembling the Sony A80K OLED, we've determined that the OLED panel itself is likely the source of the failure, and it's not worth repairing. It's been permanently removed from this test.
  • 05/08/2023: We've adjusted how we've been running the monitors in this test based on feedback from Samsung Display. We were previously maintaining the 16:9 aspect ratio of the CNN feed, even on widescreen monitors. Samsung Display pointed out that this actually increases the brightness of the CNN feed, as the letterbox bars result in a lower overall average APL. We've adjusted all three monitors to stretch the content to match the monitor's aspect ratio.
  • 05/08/2023: The Sony A80K OLED has completely failed and has been removed from the test. A column of blue light is always on in roughly the same spot as the green column mentioned below. The Google TV smart interface fails to load, and it keeps rebooting, getting no further than the Google TV logo each time, so we're unable to continue testing it at this time.
  • 04/28/2023: A column of green subpixels has died on our Sony A80K OLED, similar to the LG G2 OLED. Even stranger, the column of dead pixels on the G2 seems to have fixed itself and is now working properly. We're looking into both TVs to better understand what caused the columns to fail and how it could fix itself. We've already run the pixel refresh cycle on the A80K and determined that that alone isn't enough to fix the issue.
  • 04/26/2023: Our Samsung QN900A 8k QLED has failed and no longer turns on. Like the Samsung S95B OLED, this appears to be a power supply failure. We've ordered replacement parts and will update this page when we've fixed it.
  • 04/06/2023: Samsung released firmware update 1448.1 for the Samsung S95B OLED that now runs the main compensation cycle automatically after about 2,000 hours. This large compensation cycle is extremely effective at reducing the appearance of burn-in.
  • 04/03/2023: We've posted the four-month results to each review and updated the results below. We've also posted the initial measurements for the four displays we added last week. The initial measurements were taken at the same as the four-month updates, and all displays are now running on the same schedule.
  • 03/30/2023: We've added the Samsung S95C OLED to the longevity test to see if the second generation of QD-OLED panels is more or less likely to burn-in compared to the first generation panels used on the Sony A95K OLED and the Samsung S95B OLED. We've also added three monitors, the Dell Alienware AW3423DWF, the Samsung Odyssey OLED G8/G85SB S34BG85, and the LG 27GR95QE-B.
  • 03/22/2023: We've posted a video covering our latest results. You can see it here.
  • 03/21/2023: We replaced the DC power supply, and the Samsung S95B OLED is now working properly. It has been returned to the regular longevity test schedule and runs normally.
  • 03/13/2023: After a brief delay, the Sony 42" A90K OLED has started a two-week run with a modified schedule. It'll display CNN on a 4.5-hour on, 4.5-hour off cycle, allowing it to run 21 compensation cycles per week. The test is scheduled to run until March 27th.
  • 03/09/2023: We've posted the findings from our first investigations on our first results page here.
  • 03/08/2023: Added the changelog with everything that's happened in this test so far.
  • 03/07/2023: The Hisense U7G has been repaired and returned to the test. We replaced the burnt power wire, power supply, and LED driver board, and it now appears to be working properly.
  • 03/06/2023: Our Samsung S95B OLED no longer powers on. We've removed it from the test and ordered replacement parts. The issue appears to be with the power supply.
  • 02/28/2023: The Sony A95K OLED and the Samsung S95B OLED have completed the image retention fix trial and have restarted the longevity test.
  • 02/27/2023: We're starting a new sub-test with the 48-inch LG C1 OLED and the 42-inch Sony A90K OLED. We want to see if they experience image retention when we reverse the schedule, allowing the LG to only run three compensation cycles per week, but allowing enough time for the Sony to run three per day. This test is expected to run for about three weeks.
  • 02/21/2023: We've started a new trial with the Samsung S95B OLED and the Sony A95K OLED, so they've been removed from the regular test. We're running an image retention fix video to see if we can reduce the amount of burn-in on the TVs. The five Sony TVs that previously ran this test have completed it and have restarted the longevity test.
  • 02/16/2023: We've posted the two-month results for the other 28 TVs.
  • 02/14/2023: We've started a trial with the Sony A80J, A90J, A8H, A90K, and A80K, so they've been removed from the regular test. We're running an image retention fix video to see if we can reduce the amount of burn-in on the TVs.
  • 02/06/2023: Month 2 results have been posted for 72 TVs. We're still working on analyzing data for the other 28 TVs.
  • 02/02/2023: A single column of green subpixels has died on our LG G2 OLED. We're leaving it in the test for now to see if the issue spreads.
  • 01/23/2023: The backlight on the Hisense U7G has failed. It still powers on, and we can see that the LCD layer is still working, but there's almost no light output. We dismantled it and discovered that a connector had overheated and burned. We've pulled it from the test and ordered replacement parts.
  • 12/01/2022: The Sony X95J has developed severe uniformity issues on the left side of the screen. It looks like some of the LEDs are starting to fail.
  • 11/18/2022: We've adjusted the test schedule based on reader feedback. There are now a few longer off periods during the week to allow the Sony OLEDs time to run their compensation cycles, as they need to be off for four hours before the cycle will run.
  • 11/16/2022: Today marks the official start of the longevity test. We plan on running the test for at least two years, until the end of 2024.
