      If the screen image looks abnormal, try these steps: 1. Press the 'AUTO' button on the remote to automatically optimize the screen. 2. If the result is not satisfactory, navigate to [PICTURE] - [Screen] - [Position] in the OSD menu. 3. Verify that the video card resolution and frequency are supported.

    Why does after-image appear on my LG Digital Signage?

      Timothy FergusonAug 27, 2025
      An after-image may appear because: * The pixels may be damaged if a fixed image is displayed for an extended period. To prevent this, use the screen-saver function. * Image sticking can occur when a dark image is displayed after a high contrast image (black and white or gray). This is normal for LCD screens.

      An after-image may appear on your LG Digital Signage due to using a fixed image for a long time, which can damage the pixels; use the screen-saver function to prevent this. Also, when a dark image is displayed after an image with high contrast, it may cause image sticking, which is normal for LCD screen products.

      If the screen color on your LG Media Player is abnormal, try setting the number of colors to more than 24 bits (true color) via Control Panel - Display - Settings - Color Table menu in Windows.
