  If nothing is displayed on your LG Monitor, first ensure the power cord is correctly plugged into the outlet and that the power cable is properly connected. Press the power button. Also, verify that the connected input is enabled in the monitor's menu (Menu > Input). If the monitor is in sleep mode, try moving the mouse or pressing a key on the keyboard. Confirm that your computer is turned on. Check the signal cable and reconnect it if necessary. If the issue persists, ensure you have installed the display driver from the LG website and that your graphics card supports Plug and Play.

  If the display color on your LG Monitor appears abnormal, ensure that the color is set to 24 bit (true color) or higher. For Windows, navigate to Control Panel > Display > Settings > Color Quality to adjust this setting. Also, check the signal cable for proper connection; reconnect it or reinsert the PC's graphics card. Note that some color variations may not be errors or related to the monitor's performance.
