  If your LG Monitor's screen display is unstable or shaky, or if images leave shadow trails, it could be due to the resolution being set to HDMI 1080i 60/50 Hz (interlaced). Try changing the resolution to 1080p or the recommended resolution. It could also be caused by not setting the graphics card to the recommended (optimal) resolution. This may result in blurred text, a dimmed screen, a truncated display area or misalignment of the display.
