What to do if nothing is displayed on my LG 34WK500 Monitor screen?

If nothing is displayed on your LG Monitor screen, ensure the power cord is correctly plugged into the power outlet, testing the outlet with another device if necessary. Also, check the power cable connection and press the power button. Verify that the connected input is enabled in the monitor's settings (Settings > Input). If the monitor is in sleep mode, move the mouse or press a key on the keyboard. Confirm that your computer is turned on. If the signals from the PC are out of the monitor's frequency range, refer to the Product Specification section of the manual to set the appropriate frequency. Finally, check the cable and reconnect it.
