LG OLED evo TVs are equipped with screen protection features to help prevent image retention and reduce the risk of burn-in. The key technology is Pixel Cleaning, which refreshes the OLED pixels to maintain optimal picture quality and panel longevity.

[Settings] → [General] → [OLED Care] → [OLED Panel Care] → [Pixel Cleaning] on your TV’s menu.

 

These features help keep your OLED panel in the best condition for long-term use.

 

*Pixel Cleaning reduces, but does not eliminate, the risk of permanent image retention (“burn-in”). For best results, avoid displaying static images for extended periods. Always leave the TV plugged in after turning it off to allow automatic Pixel Cleaning to complete.
