GoKawiilRTings finds 'edge rot' pixel degradation in most tested 2020-2022 LG WOLED TVs
RTings reports that 14 of 16 LG WOLED televisions in its long-running burn-in test, all manufactured between 2020 and 2022, have developed a defect it calls 'edge rot,' where pixels along the screen edges progressively darken in a mold-like pattern. Three Samsung QD-OLED sets in the same test showed no such symptoms. RTings says it cannot yet determine whether newer LG WOLED panels, whose manufacturing reportedly improved in 2024, are affected, since its test period ended in 2025.
GoKawiil's interpretation of the reporting above, not reported fact.
The findings suggest a previously under-reported failure mode distinct from burn-in, potentially affecting a large share of LG OLED TVs sold during a three-year window now mostly out of standard warranty. LG's five-year panel warranty, which covers only select high-end lines purchased since 2021, could leave many owners of affected sets without recourse, though the company attributes the issue to environmental conditions like humidity rather than a manufacturing defect.
- 87.5% (14 of 16) of LG WOLED TVs in RTings' 2020-2022 test batch show 'edge rot' pixel degradation.
- Samsung's QD-OLED panels in the same test appear unaffected, though only three units were tested.
- LG's extended panel warranty only applies to certain high-end series purchased from 2021 onward, leaving many affected owners uncovered.
