Important Information for
Preventing Image Retention
OLED is a self-emissive technology, which brings many significant
benefits to image quality and performance. As with any self-emitting
display, it is possible for users of OLED TVs to experience temporary
image retention under certain conditions, such as when displaying a
static image on the screen for a long time. LG OLED TVs incorporate
dedicated functions that protect the screen from possible image
retention.
If a static image persists on screen, screen brightness is automatically
reduced in specific areas of, or across the entire screen. Once the static
image disappears, screen brightness will automatically return to its
prior setting. This is not a product malfunction.
Examples of Images that may Cause
Image Retention
•
Still images or fixed images containing certain information
that are displayed uninterrupted on the screen, such as channel
numbers, station logos, program titles, news or movie subtitles,
and headlines.
•
Fixed menu or icons for video game consoles or broadcasting
set-top boxes.
•
Black bars shown on the left, right, top, or bottom of the screen,
such as in images with a 4:3 or 21:9 ratio.

Information on Functions
Supporting Image Quality in
Relation to Temporary Image
Retention
•
LG OLED TVs provide a feature called Pixel Refresher, 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 Refresher 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
Refresher. This feature will run for 1.5 hours 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 Refresher via the TV menu:

•
Whenever you watch your TV for more than four cumulative hours,
Pixel Refresher will be automatically activated for a few minutes
once your TV is turned off. (Note: Pixel Refresher will not be
activated if the power cord of your TV is not plugged in or the main
power is off.)
