  If you are experiencing an unstable and shaky screen display or shadow trails on your LG Monitor, and the resolution is set to HDMI 1080i 60/50 Hz (interlaced), the screen may be flickering. Try changing the resolution to 1080p or the recommended resolution. Also, ensure that your graphics card is set to the recommended (optimal) resolution. If not, it may result in blurred text, a dimmed screen, a truncated display area, or misalignment. If issues persist, contact the manufacturer of your computer or graphics card for assistance.
