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, 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:
• 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
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 colors
(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 50 ºF and 104 ºF (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 colors or logos etc.
