Image retention
OLED
TV’s are susceptible to image retention (burn-in) due to the characteristics of
the materials used. Image retention may occur if images are displayed in the
same location on the screen repeatedly or over extended periods of time. This
is not a malfunction of the TV. Avoid displaying images that may cause image
retention.
The following are
examples of images that may cause image retention:
•Content
with black bars either on the top and bottom and/or the left and right sides of
the screen. (for example, Letterboxed, 4:3 screen, Standard definition)
•Static images such as photos.
•Video games that might have static content in some part of the screen.
•On-screen menus, program guides, channel logos etc.
•Static content from applications.
•On-screen tickers, such as those used for news and headlines.
To reduce the risk of image retention:
•Fill
the screen by changing [Wide mode] to eliminate the black bars. Select [Wide
mode] other than [Normal].
•Turn off the OSD (On Screen Display) by pressing the DISPLAY button, and turn
off the menus from connected equipment.
For details, refer to the instruction manuals for the connected equipment.
•Avoid displaying static images with bright colours (including white), clocks
or logos on any portion of the screen.
•Set the picture settings based on the ambient conditions. The Standard Picture
is recommended for home use and when viewing content that often displays the
station logos, etc.
The TV has following features to help reduce/ prevent image retention.
Press the HOME button, then select [Settings] – [Picture & Display] – [Expert
panel settings] – the desired option.

refresh will automatically run to adjust the uniformity of the TV screen after
it has been in use for long periods of time.
Panel refresh can also be performed manually and should only be used if image
retention is very noticeable or you see the following message:
[Panel refresh did not finish...]

•The Panel refresh function may affect the panel. As a reference, perform the
Panel refresh only once a year, do not perform it more than once a year as it
may affect the usable life of the panel.
•Panel refresh takes about one hour to complete.
•A white line may be displayed on the screen during the Panel refresh, this is
not a malfunction of the TV.

ºC.
