      Jerry MorrisJul 29, 2025
      If no image appears on your LG Monitor, ensure the power cord is properly connected to the outlet and that the monitor is turned on using the Power button. If the monitor is in power saving mode, try moving the mouse or pressing a key on the keyboard. Also, verify that your PC is turned on and the signal cable between the PC and the monitor is securely connected. If the signal from the PC is out of the display's frequency range, consult the 'Specifications' section of the manual to configure your display.
