  If your LG Digital Signage displays no image, first, ensure the power cord is securely plugged into the power outlet. Then, verify the signal cable connection between your PC and the signage. Next, access the input menu to confirm the correct input signal is selected. Lastly, check if the PC's graphics card signal is within the product's vertical or horizontal frequency range, adjusting as necessary according to the specifications in the manual.

  If the screen image on your LG Digital Signage looks abnormal, verify that the graphics card resolution and frequency are supported by the product. If the frequency is out of range, set to the recommended resolution in the [Control Panel] ? [Display] ? [Setting] menu. Also, ensure the correct input signal is connected to the appropriate signal port by using a matching signal cable.

  Joshua MartinezAug 25, 2025
  If the screen color on your LG Digital Signage appears abnormal, set the number of colors to more than 24 bits (true color) by going to [Control Panel] ? [Display] ? [Settings] ? [Color Table] in Windows. Also, check the connection status of the signal cable. Note that several pixels (red, green, blue, white, or black color) may appear on the screen; this is not a malfunction of the LCD but a unique characteristic.

  If you notice after-image appearing on your LG Digital Signage, and you've been using a fixed image for an extended period, the pixels may be damaged; use the screen-saver function to prevent this. Also, 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.
