Motion Blur vs Ghosting: What’s the Difference?
Understand motion blur, ghosting, inverse ghosting and pixel response behavior, then learn how to test them correctly in your browser.
Motion blur and ghosting are often described as the same thing, but they are different visual effects. Separating them makes it easier to choose the right setting or decide whether a display response problem is actually present.
Motion blur
Motion blur is a loss of detail while an object moves. Some blur comes from the way sample-and-hold displays present frames, some comes from pixel response time, and some can come from the source content itself.
Ghosting
Ghosting is a visible trail behind or around a moving object. It is easiest to see when a high-contrast target moves across a flat background. Gray-to-gray transitions can reveal behavior that black-to-white motion does not.
Inverse ghosting
Overdrive can make pixels change faster, but too much overdrive may overshoot the intended level and create a bright or dark halo. This is commonly called inverse ghosting or overshoot.
How to compare displays or settings
- Use the same browser and zoom level.
- Run the same target speed.
- Compare standard and gaming/overdrive modes.
- Keep brightness reasonably similar.
- Watch the moving target itself, not only the background.
What to look for
A clean result keeps edges recognizable during motion. A mild trail may be normal for a slower transition. A strong repeated shadow, colored halo or obvious overshoot is more useful evidence of response behavior.
Refresh rate matters too
Higher refresh rates can make motion appear smoother and reduce the distance an object travels between updates, but refresh rate alone does not guarantee fast pixel response. A high-Hz panel can still ghost if its transitions are slow.

Remember: browser diagnostics are observational tools. They can reveal repeatable visual symptoms, but they do not replace laboratory measurement or a technician when hardware diagnosis is required.
