  There might be several reasons why your LG Digital Signage is not displaying an image. First, ensure that the power cord is correctly plugged into the power outlet. Also, check the signal cable and access the input menu to verify the input signal. If the signal from the PC's graphics card is out of the product's vertical or horizontal frequency range, adjust the frequency range according to the specifications.

  If the screen image on your LG Digital Signage looks abnormal, it could be due to the graphics card resolution and frequency not being supported by the product. Verify that the graphics card resolution and frequency are supported. If the frequency is out of range, set it to the recommended resolution in the “Display” settings in the Control Panel. Another potential cause is an improper input signal connected to the signal port. Ensure that you connect the appropriate signal cable that matches the source input signal.

  If the screen color on your LG Digital Signage appears abnormal, set the number of colors to more than 24 bits (true color) via Control Panel - Display - Settings - Color Table menu in Windows. Also, check the connection status of the signal cable, or try re-inserting the PC graphics card. Note that this may not be a malfunction of the LCD.

What to do if after-image appears on LG Digital Signage?

  Eddie McculloughAug 23, 2025
  If an after-image appears on your LG Digital Signage, and you've been using a fixed image for a long time, the pixels may be damaged; try using the screen-saver function. Also, the appearance of a dark image after displaying an image with high contrast (black and white or gray) can cause image sticking, which is normal for LCD screen products.
