      If your LG Monitor displays nothing, it could be due to a missing or disconnected signal cable between your PC and the monitor. Check the cable and reconnect it securely. Also, the signals transferred from the PC (graphics card) might be out of the horizontal or vertical frequency range of the monitor. Refer to the Product Specification section of this manual to set the appropriate frequency.
