Why is my LG 27BL55U screen display unstable and shaky?

  regina25Aug 26, 2025
  An unstable or shaky display, or images leaving shadow trails on your LG Monitor, may occur if the selected resolution is HDMI 1080i 60/50 Hz (interlaced). Try changing the resolution to 1080p or the recommended resolution. If your graphics card isn't set to the optimal resolution, it may cause blurred text, a dimmed screen, a truncated display area, or misalignment. Setting methods vary, and some resolutions might not be available depending on your graphics card's performance.
