Monitors & displays

Monitor shows ghosting or motion blur

Ghosting, where moving objects leave a faint trail, is usually caused by the monitor's response time setting or refresh rate rather than a hardware fault.

Symptoms

  • Faint trailing image behind moving objects, especially in games or fast video
  • Trails are more visible on dark backgrounds
  • Problem is worse at higher refresh rates
  • Text or cursor leaves a faint smear when moved quickly

Likely causes

  • CommonResponse time (overdrive) setting too lowMost monitors have an adjustable pixel response setting that reduces ghosting when raised.
  • CommonRefresh rate set below the monitor's capabilityRunning at a lower refresh rate than the panel supports can make motion look blurrier.
  • PossibleVSync or adaptive sync misconfiguredSync settings interacting poorly with the game or app can cause visible ghosting or judder.
  • PossiblePanel technology limitationSome budget VA panels naturally have more ghosting than IPS or TN panels, which is a hardware trait, not a fault.

What to do

  1. Open the monitor's on-screen menu and find the Response Time or Overdrive setting, then try raising it one level at a time.
  2. Confirm the display is running at its maximum supported refresh rate in Display Settings.
  3. In the graphics driver's control panel, enable or disable VSync/G-Sync/FreeSync and compare which setting reduces ghosting for your use case.
  4. Test with a dedicated motion test website (search 'UFO test ghosting') to compare settings side by side.
  5. If overdrive is already high and ghosting looks like a bright trailing halo instead of a faint smear, lower the overdrive setting one notch, since too-high overdrive causes its own artifact called 'inverse ghosting.'
  6. Accept that some panel types (typically budget VA panels) have inherently more ghosting; if this is unacceptable, an IPS or TN panel of similar size will generally show less.

When to call a pro

This is a settings and panel-technology issue rather than something to repair; if ghosting is unacceptable after tuning settings, a different monitor with a faster panel type would be the practical fix.
