Why am I seeing this Ranked on source trust — TechPowerUp
It ranks mainly on source trust: TechPowerUp is the most reliable outlet we track on this subject, and is the only one on the story so far.

Fourteen of sixteen WOLED televisions failed during RTINGS' 18,000-hour longevity test, which simulates roughly ten years of typical viewing. The affected sets developed dead pixels and damage along panel edges, a phenomenon RTINGS calls edge rot. All used LG Display panels manufactured between 2020 and 2023. Older WBC panels showed the worst results, with nine of ten units affected and five rated severe, while five of six newer WBE panels also exhibited the problem.
Only two models escaped damage: the LG A2 and LG G3. The three QD-OLED televisions tested—Samsung's S95B and S95C and Sony's A95K—showed no dead pixels, though RTINGS notes this sample size is too small to confirm QD-OLED immunity. Unlike burn-in, edge rot occurs regardless of content watched, making standard viewing habits irrelevant to prevention.
RTINGS suspects manufacturing contamination or defects in the encapsulation layer that protects against moisture. LG stated the issue may appear in a small number of products under extreme heat, humidity, or harsh conditions, not during normal use. RTINGS lowered its reliability ratings for WOLED models and plans to test 2025 and 2026 units, including those with LG's RGB Tandem panels, to determine if the problem has been resolved.
What happened
Fourteen of the 16 WOLED TVs in RTINGS ' 18,000-hour accelerated longevity test developed what the outlet calls "edge rot," meaning dead pixels and other damage creeping in along the panel edges. All of these sets use LG Display panels and were released between 2020 and 2023, and the test works out to roughly ten years of typical U.S. viewing. Older WBC panels fared worst, with nine of ten affected and five rated severe, while five of six newer WBE panels also showed it. Only the LG A2 and LG G3 came out clean. Meanwhile, the three QD-OLED TVs in the test, Samsung's S95B and S95C and Sony's A95K, didn't have a single dead pixel. However, RTINGS says three units are too few to call QD-OLED immune.
