Why is the screen color abnormal on my LG Digital Signage?

  Daniel GregoryAug 26, 2025
  If the screen color on your LG Digital Signage is abnormal, set the number of colors to more than 24 bits (true color) by selecting [Control Panel] ? [Display] ? [Settings] ? [Color Table] in Windows. Also, check the connection status of the signal cable and re-insert the PC graphics card. Note that several pixels (red, green, blue, white, or black color) may appear on the screen due to the unique characteristics of the LCD panel, and this is not a malfunction.
