  If nothing is displayed on your LG Monitor screen, try the following: Ensure the power cord is correctly plugged into the power outlet. Check the power cable connection and press the power button. Verify that the connected input is enabled by going to Menu > Quick Settings > Input. If the monitor is in sleep mode, move the mouse or press any key on the keyboard. Also, ensure your computer is turned on. If the signals from your 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.

  If the display color on your LG Monitor is abnormal, try setting the color to 24 bit (true color) or higher via Control Panel > Display > Settings > Color Quality in Windows. Also, check if the signal cable is properly connected, and reconnect the cable or reinsert the PC's graphics card. Note that sometimes, this is not an error and is unrelated to the monitor's performance.
