What to do if my LG 24BK550Y Monitor says no signal?

If your LG Monitor displays a 'No Signal' message, first, ensure the cable connecting your PC and the monitor is properly connected. If it is, reconnect it securely. If the monitor enters DPM (Display Power Management) mode with the power LED off, press the DC button twice to wake up the screen.
