What to do if my LG 34WQ75C-B.AAU Monitor screen display is unstable and shaky?

  If your LG monitor's screen display is unstable or shaky, or if images displayed on the monitor leave shadow trails, and the selected resolution is HDMI 1080i 60/50 Hz (interlaced), the screen may be flickering. Try changing 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 the screen display on your LG Monitor is unstable and shaky, or if images leave shadow trails, 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. In addition, 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. The setting methods may be different depending on the computer or operating system, and some resolutions may not be available depending on the performance of the graphics card. If this is the case, contact the manufacturer of the computer or graphics card for assistance.
