Why is my LG 27UP850N-W Monitor screen display unstable and shaky?
- A
  Amanda JohnsonAug 8, 2025
  If your LG Monitor's screen display is unstable or images leave shadow trails: * If the resolution is HDMI 1080i 60/50 Hz (interlaced), the screen may flicker. Change the resolution to 1080p or the recommended resolution. * Blurred text, a dimmed screen, a truncated display area, or misalignment can occur if the graphics card isn't set to the recommended resolution. Setting methods vary by computer and OS, and some resolutions depend on the graphics card's performance. If issues persist, consider contacting the computer or graphics card manufacturer.

  If image sticking occurs on your LG Monitor even when it's turned off, it could be due to displaying a still image for a prolonged time, which may damage the screen and cause image retention. To extend the monitor's lifespan, use a screensaver.
