  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.
