Information on Functions Supporting Image Quality in Relation to Temporary
Image Retention
• LG OLED TVs provide a feature called Pixel Cleaning, which helps to prevent temporary image retention.
• When the accumulated television viewing time reaches 2,000 hours or more (this is equivalent to watching TV for five hours a day over the
course of a year), Pixel Cleaning will be automatically activated once your TV is turned off. When turning off your TV, a notice will appear
on the screen informing the activation of Pixel Cleaning. This feature will run for an hour while your TV is turned off. A horizontal line may
appear at the top or bottom of the screen when the process is almost finished.
• You may also manually activate Pixel Cleaning via the TV menu:
• Whenever you watch your TV for more than four cumulative hours, Pixel Cleaning will be automatically activated for a few minutes once
your TV is turned off. (Note: Pixel Cleaning will not be activated if the power cord of your TV is not plugged in or the main power is off.)
