The 20/7 burn-in test ran for about two years, from August 31, 2017, until November 15, 2019. With new panels, new heatsinks, and even brand-new panel types like QD-OLED, there are a lot of unknowns. It's generally accepted that burn-in isn't as much of an issue as it used to be, but it's unclear just how much better the newer OLED TVs are. Although burn-in isn't the main goal of this test, we're hoping to better understand how newer OLED panels compare to the older generation of OLEDs. To that end, we've decided to start a new accelerated longevity test to better understand how long new TVs should last and what are the most common points of failure. However, we still haven't addressed the issue of longevity in general, and we don't know if newer OLED panels are still as likely to experience burn-in. This test ended in 2019, as we feel that we now have a good understanding of what types of content are likely to cause burn-in. Follow along for our updates over the next two years on our new RTINGS com R&D Channel. You can learn more about how we designed and built this test in our latest video. We've started a new 100 TV accelerated longevity test, and one goal of that test is to better understand how well modern TVs handle image retention and burn-in. This test was supplemented by our real-life OLED burn-in test, which started in January 2018. We tested three TVs side-by-side, the OLED LG B6, the VA Samsung KU6300, and the IPS LG UJ6300 in a two-year-long test. Permanent image retention is a more serious issue, but it requires looking at the TV's performance over months or years. It's a temporary annoyance and results in some faint artifacts usually visible in high-contrast areas. We already test for temporary image retention, which generally subsides over a few minutes. Our goal was to see how their performance changed over time, especially with static images like network logos, black bars in movies, or video games with a fixed interface. On August 31, 2017, we started a long-term 20/7 burn-in test on 3 TVs (OLED vs VA vs IPS).
