  If the screen color on your LG Monitor appears abnormal, it could be due to several reasons: * The number of colors might be set to 16 colors. To fix this, set the number of colors to more than 24 bits (true color) via [Control Panel] ? [Display] ? [Settings] ? [Color Table] in Windows. * There might be a connection issue with the signal cable, so check its connection status. * Try re-inserting the PC graphics card. Also, note that the appearance of a few red, green, blue, white, or black pixels is not a malfunction of the LCD.

  If the screen image on your LG Digital Signage looks abnormal, verify that your graphics card resolution and frequency are supported by the product. If the frequency is out of range, adjust it to the recommended resolution via the [Control Panel] [Display] [Setting] menu. Also, ensure the correct input signal is connected to the appropriate signal port. If condensation is present, allow some time after powering on for it to dissipate. Finally, regularly clean the heat exchanger to prevent internal temperature increases.
