  If no image appears on your LG Monitor, first, check that the power cord is properly connected to the power outlet. If that's not the issue, and the signal cable between the PC and the monitor is either missing or disconnected, check the cable and reconnect it, and verify your PC's status. This message might also appear if the signal from the PC (video card) is out of the horizontal or vertical frequency range of the display. In this case, consult the 'Specifications' section of this manual and configure your display again.
