  If nothing is displayed on your LG Monitor's screen, first ensure the power cord is correctly plugged into the outlet and that the power cable is properly connected. Press the power button. Also, verify that the correct input is enabled by going to Menu > Quick Settings > Input. If the monitor is in sleep mode, try moving the mouse or pressing a key on the keyboard.

Finally, check the cable and try reconnecting it.
