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.
