LG A1 OLED
Our accelerated longevity test has been running for over three months now, and we've already encountered some very interesting results. 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 read more about our longevity test, and how we set it up, be sure to 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.
Results Changelog (Last Updated 03/21/2023)
- 03/21/2023: We replaced the DC power supply, and the Samsung S95C OLED is now working properly. It has been returned to the regular longevity test schedule and is now running 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 has 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.
