  If the display color on your LG Monitor is abnormal, set the color to 24 bit (true color) or higher. In Windows, go to Control Panel > Display > Settings > Color Quality to adjust this. Check if the signal cable is properly connected, and if not, reconnect it or reinsert the PC's graphic card. Note that sometimes, this is not an error related to the monitor's performance.
