  If your LG Digital Signage display shows no image, first ensure the power cord is securely plugged into the power outlet. Also, verify the signal cable between your PC and the display is properly connected. Try pressing the INPUT menu on the remote control to select the correct input signal. If the signal from the PC is out of the vertical or horizontal frequency range of the product, adjust the frequency range by referring to the Specifications, noting that the maximum resolution is 1920 x 1080 (60Hz).

  If the screen color on your LG Digital Signage is abnormal, ensure that the number of colors is set to more than 24 bits (true color) via Control Panel - Display - Settings - Color Table in Windows. Check the connection status of the signal cable and re-insert the PC video card. Note that several pixels (red, green, white, or black) may appear on the screen, which is not a malfunction of the LCD.

  If an after-image appears on your LG Digital Signage, and you use a fixed image for a long time, this may damage the pixels, so use the screen-saver function. Also, when a dark image is displayed on the screen after an image with high contrast (black and white or gray), this may cause image sticking, which is normal for LCD screen products.
