Review web site Rtings.com has performed an extensive accelerated longevity test for over three months, testing the latest QD-OLED and WOLED TVs.y
Rtings reports that both QD-OLED displays (Samsung S95B OLED and the Sony A95K) showed signs of image retention, and it seems in general that the QD-OLED displays suffer from worse problems compared to LG's WOLED. Some of Sony's WOLED TVs also showed signs of image retention.
We have to remember that these tests are not the usual viewing usage of consumers. Previous tests by Rtings.com in 2017 have shown serious burn-in problems in LG's OLED TVs, but most consumers (me included) did not face any problems even after many years.
It is also important to note that the TV's at Rting.com tests are Samsung's first-gen QD-OLED panels. The company improved the performance of its panels in 2023 and it is likely that the new TVs will also suffer less from burn-in.
