Why is my LG 34WQ75X Monitor screen display unstable and shaky?

  higginsdavidAug 2, 2025
  An unstable or shaky display, or images leaving shadow trails on your LG Monitor, can occur if the selected resolution is HDMI 1080i 60/50 Hz (interlaced). To resolve this, change the resolution to 1080p or the recommended resolution. Also, not setting the graphics card to the recommended (optimal) resolution may result in blurred text, a dimmed screen, a truncated display area or misalignment of the display.

  If you're not getting any sound from the headphone port on your LG Monitor, ensure the headphone port connections are properly made. You can also try increasing the volume using the joystick. Additionally, set the audio output of the PC to the monitor you are using. The settings may differ depending on your operating system.
