Precautions to Protect the Screen from
Damage
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, programme 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:
• Sony recommends that you turn off the TV normally by pressing
the power button on the remote control or the TV.
• 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 /
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.
Panel refresh
Panel 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…]
Caution:
• 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.
• Panel refresh will only work when the room temperature is
between 10 ºC and 40 ºC.
Pixel shift
Automatically moves the image on the screen to prevent image
retention.
Other feature
The screen brightness is automatically reduced when displaying
still images, clocks, bright colours or logos etc.
