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.
