  If the screen color is abnormal on your LG Digital Signage, set the number of colors to more than 24 bits (true color) by selecting Control Panel - Display - Settings - Color Table menu in Windows. Check the connection status of the signal cable and try re-inserting the PC video card. Note that several pixels (red, green, white or black color) may appear on the screen due to the unique characteristics of the LCD panel, which is not a malfunction.

  If the screen image on your LG Monitor looks abnormal, and you're using a D-Sub analog signal, press the "AUTO" button on the remote to automatically optimize the screen. If it's still not right, go to [PICTURE] - [Screen] - [Position] in the OSD menu. Also, check that your video card resolution and frequency are supported; if the frequency is too high, set it to the recommended resolution in the Control Panel "Display" settings. Ensure the correct input signal is connected to the appropriate port.

Why does after-image appear on my LG 65LS33A Digital Signage?

  christinehernandezSep 10, 2025
  An after-image may appear on your LG Digital Signage if a fixed image is displayed for a long time, potentially damaging pixels. Use the screen-saver function to prevent this. Also, displaying a dark image after a high-contrast image (black and white or gray) can cause image sticking, which is normal for LCD screens.
