  Sergio RobertsonJul 27, 2025
  If nothing is displayed on your LG Monitor screen, ensure the power cord is correctly plugged into the power outlet, testing the outlet with another device. Also, check the power cable connection and press the power button. Verify that the connected input is enabled via Menu > Input > Input list. If the monitor is in sleep mode, move the mouse or press any key. Confirm that your computer is turned on. If signals from the PC are out of the monitor's frequency range, refer to the Product Specification section of the manual to set the appropriate frequency. Finally, check the cable and reconnect it.
