  If your LG Monitor screen is blank, start by ensuring the power cord is securely plugged into the outlet and that the outlet has power by testing it with another device. Check the monitor's power cable connection and press the power button. Verify that the correct input is enabled via the Menu. If the monitor is in power-saving mode, move the mouse or press a key. Also, make sure your computer is turned on. Check the cable and reconnect it.

What to do if there is no sound from the headphone port on my LG 24GM77 Monitor?

  Amy GoldenAug 1, 2025
  If you're not getting any sound from the headphone port on your LG Monitor, remember that D-Sub and DVI cables do not support audio, so audio support depends on the cable type. Ensure the headphone port connections are properly made. Increase the volume using the joystick. Finally, set the PC's audio output to the monitor by going to Control Panel > Hardware and Sound > Sound and setting the monitor as the default device.

  Kim WatkinsAug 6, 2025
  If your LG Monitor's screen display is unstable, shaky, or images leave shadow trails, it might be due to the resolution being set to HDMI 1080i 60/50 Hz (interlaced). Change the resolution to 1080P or the recommended resolution to resolve this issue.

  If the display color on your LG monitor appears abnormal, first, set the color to 24 bit (true color) or higher by navigating to Control Panel > Display > Settings > Color Quality in Windows. Next, check the signal cable for proper connection, reconnecting it or reinserting the PC's video card. Note that pixilated spots (red, green, blue, white, or black) may appear, which is normal for LCD screens and not related to the monitor's performance.
