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

Recommendations For Preventing Image Retention
· [Screen Move] Moving the screen minutely at regular intervals helps to prevent panel noise caused by images that have been fixed for a long time.
It is recommended to set Circle Menu > [OLED Care] > [Screen Move] to on. · [Screen Saver] If there is no movement on the screen for a certain period of time, the screen turns off automatically.
It is recommended to set Circle Menu > [OLED Care] > [Screen Saver] to on. · [Image Cleaning] Corrects screen problems that may occur when the monitor is turned on for a long time. Calibration will take approximately 10 minutes to complete.
It is automatically executed when entering power saving mode or turning off the power after more than 4 hours of use from the previous [Image Cleaning] completion.
It can be operated manually in Circle menu > [OLED Care] > [Image Cleaning]. · [Pixel Cleaning] Corrects pixel problems that may occur when the monitor is turned on for a long time. Calibration will take approximately 1 minute to complete.
It is automatically executed when entering power saving mode or turning off the power after more than 500 hours of use from the previous [Pixel Cleaning] completion.
It can be operated manually in Circle menu > [OLED Care] > [Pixel Cleaning].

ENGLISH

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.
