      If the display color is abnormal on your LG Monitor, here are a few things to check: * Set the color to 24 bit (true color) or higher. In Windows, go to Control Panel > Display > Settings > Color Quality. * Ensure the signal cable is connected properly. Try reconnecting the cable or reinserting the PC's video card. * When using the monitor, pixilated spots (red, green, blue, white or black) may appear on the screen. This is normal for the LCD screen.
