Protecting the TV Screen (OLED TV)

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.
