      First, ensure the power cord is securely plugged into the power outlet and the power switch is turned on. Also, verify the cable connection. If the issue persists, check if the input setting is correct by navigating to [All Settings] > [Input]. Finally, if signals from the PC's graphics card are out of the monitor's frequency range, refer to the section of this manual to set the appropriate frequency.

    Why is the display color on my LG Monitor abnormal?

      Gerald HicksAug 26, 2025
      First, set the number of colors to 24 bit (true colors) or higher. This can usually be found in Windows Control Panel under Display > Settings > Color Quality, though the exact path may vary depending on your operating system. If that doesn't resolve the issue, check if the signal cable is properly connected. Try reconnecting the cable or reinserting the PC's graphics card. Note that sometimes, what appears to be an abnormal display color is not an error and is unrelated to the monitor's performance.

Note that pixilated spots (red, green, blue, white, or black) may appear; this is normal for an LCD screen and not related to the monitor's performance.
