  Troy ThomasAug 13, 2025
  If nothing is displayed on your LG Monitor screen, first, ensure the power cord is correctly plugged into the power outlet. Then, check the power cable connection and press the power button. Also, verify that the connected input is enabled in the settings (Settings > Input). If the monitor is in sleep mode, move the mouse or press any key on the keyboard. Make sure your computer is turned on. If the signal cable between your PC and the monitor is missing or disconnected, check the cable and reconnect it. Finally, install the display driver from the LG website and check if the graphics card supports Plug and Play.

  If the display color on your LG Monitor is abnormal, set the color to 24 bit (true color) or higher by navigating to Control Panel > Display > Settings > Color Quality in Windows. Also, check if the signal cable is connected properly by reconnecting the cable or reinserting the PC's graphics card. If these steps don't resolve the issue, remember that it might not be an error related to the monitor's performance.
