      If no image is displayed on your LG Digital Signage, first, ensure the power cord is correctly plugged into the power outlet. Then, verify the signal cable between the PC and the product is securely connected. Use the INPUT menu on the remote control to check the input signal. Also, the signal from the PC (video card) may be out of the vertical or horizontal frequency range, so adjust the frequency range by referring to the Specifications, noting the maximum resolution: 1920 x 1080 (60Hz).

    Why is the screen color abnormal on my LG 49LS75A?
    • C
      Crystal PowellAug 22, 2025
      If the screen color on your LG Digital Signage is 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 and try re-inserting the PC video card. Note that several pixels (red, green, white, or black color) may appear on the screen, which is attributable to the unique characteristics of the LCD panel and not a malfunction.

    How to prevent after-image on LG 49LS75A?
    • D
      Daniel ThomasAug 30, 2025
      If an after-image appears on your LG Digital Signage, and you've been using a fixed image for a long time, this may damage the pixels; use the screen-saver function. 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.
