  If nothing is displayed on your LG Monitor screen, ensure the power cord is correctly plugged into the outlet. Also, verify the power cable connection and press the power button.

Check if the signal cable is properly connected; reconnect it or reinsert the PC's graphic card. Note that sometimes this is not an error and is unrelated to the monitor's performance.
