Why is my LG Monitor screen display unstable and shaky?
- R
  Robert McdonaldAug 10, 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.
