Frequently Asked Questions
Why does my LG OLED dim only during football?
A full green screen of grass with a static scoreboard triggers the OLED thermal limiter to protect organic pixels from heat buildup.
Does disabling Energy Saving hurt the OLED panel?
No, turning off Energy Saving simply allows the panel to operate at its calibrated factory brightness levels.
