  If your LG Monitor screen is blank, ensure the power cord is securely plugged into the outlet and that the power cable is properly connected. Also, press the power button. If that doesn't work, make sure the correct input is enabled by going to Menu > Quick Settings > Input. If the monitor is in sleep mode, try moving the mouse or pressing a key on the keyboard. Finally, verify that your computer is turned on. If the issue persists, check the cable and reconnect it.

  If there's no sound coming from the headphone port on your LG Monitor, first, ensure that the headphone connections are properly made. If that doesn't work, try increasing the volume using the joystick. As a last step, set the audio output of your PC to the monitor you are using.

  Miranda RoyAug 7, 2025
  If the display color on your LG Monitor looks abnormal, first, set the color to 24 bit (true color) or higher. In Windows, this can be found under Control Panel > Display > Settings > Color Quality. If that doesn't resolve the issue, check the signal cable for a proper connection. Try reconnecting the cable or reinserting the PC's graphics card. Note that it's normal for LCD screens to have some pixilated spots (red, green, blue, white, or black).
