ENGLISH
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
• You can prevent image retention using monitor menu settings. (Go to [Settings] > [General] > [OLED Screen
Move] / [OLED Screen Saver] / [OLED Image Cleaning])
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.
