Important Information for Preventing Image Retention
Unlike regular LED/LCD monitors, pixels in the OLED monitors emit light on their own, achieving a perfect black and creating clear images without blurring of light.
Image retention does not occur in normal use of the product, but can occur if the same screen is watched for a long time. Built-in features are available to protect the screen  from possible image retention.
If a static image persists on the screen, the screen saver will automatically lower the full screen brightness, and the screen will turn off automatically after a certain period of  time. When an image change is detected, the brightness is automatically restored to its original state. This is not a malfunction of the product.
Examples of Images that may Cause Image Retention

• Static images or images containing objects/information that are constantly visible in a fixed position on the screen (e.g., icons on the desktop, fixed windows such as  menus, or logos while watching broadcasts, etc.)
• Fixed menu/icon on a game console or set-top box
• Fixed menu on the top corner of the web browser

Recommended Measures for Preventing Image Retention
Turn on [Screen Saver] and [Screen Shift] when using the monitor.

• Go to [Menu] > [Settings] > [General] and turn on [Screen Saver]. This is strongly advised.
  When [Screen Saver] is turned on, the screen automatically turns off when it is idle for a certain period of time.

• Go to [Menu] > [Settings] > [General] and turn on [Screen Shift]. This is strongly advised.
  When [Screen Shift] is turned on, the screen moves by a few pixels in four directions.

Safety precautions for prolonged use
Due to the unique properties of OLED panels, the brightness may be reduced with prolonged use. Reduced brightness is permanent.
In addition, repeated use in conditions such as high temperature and high humidity or still images/high luminance may result in afterimages, image blurring, or screen malfunction.
