If nothing is displayed on your LG Monitor screen, start by checking if the power cord is correctly plugged into the power outlet. Also, verify the power cable connection and ensure you press the power button. It's also important to check that the connected input is enabled via Settings > Input > Input list. If the issue persists, the signals transferred from your PC (graphics card) might be out of the monitor's horizontal or vertical frequency range. Refer to the Product Specification section of this manual to set the appropriate frequency. Also, check the signal cable and reconnect it, and make sure that OSD Lock is set to Off in Settings > General.
