Why does my LG 55UH5C have no image?
If your LG Digital Signage displays no image, verify that the power cord is properly connected to the power outlet, check the signal cable, and press the INPUT menu on the remote control to ensure the correct input signal is selected. Also, the signal from your PC's graphics card might be outside the product's vertical or horizontal frequency range. If so, adjust the frequency range according to the specifications in the manual.
