Why is nothing displayed on my LG 27UL550-W Monitor screen?

If nothing is displayed on your LG Monitor screen, verify the power cord is correctly plugged into the power outlet. Also, check the power cable connection and press the power button. Ensure the connected input is enabled in the settings (Settings > Input). The issue might also be due to a missing or disconnected signal cable between the PC and the monitor; check and reconnect it. Finally, signals transferred from the PC (graphics card) might be out of the monitor's horizontal or vertical frequency range. Refer to the Product Specification section of this manual to set the appropriate frequency.
