  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 in the monitor's settings (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. Check the signal cable between the PC and the monitor and reconnect it if necessary. Finally, install the display driver from the LG website and ensure your graphics card supports Plug and Play.

  If the display color is abnormal on your LG Monitor, set the color to 24 bit (true color) or higher by navigating to Control Panel > Display > Settings > Color Quality in Windows. Also, check if the signal cable is connected properly; reconnect it or reinsert the PC's graphics card. Note that pixilated spots (red, green, blue, white, or black) may appear on the screen during monitor use, which is normal and not related to the monitor's performance.
