Motion Blur and Ghosting Test

Compare motion clarity, ghost trails, overshoot and scrolling detail across multiple full-screen stages.

Motion & ghosting test

Run six full-screen motion stages instead of watching a single plain block. Compare trailing, smearing, inverse ghosting, scrolling clarity and fine moving detail.

Use the same speed and display settings when comparing monitor overdrive, response or refresh-rate modes.
6 motion stagesContrast, inverse, gray, RGB, scrolling text and fine grid.
3 speed levelsSlow, medium and fast movement with frame-independent timing.
Refresh estimateShows an approximate browser animation-frame rate for context.
Simple ratingMark each stage clean, some blur or strong ghosting and review the summary.
Direct answer

What does the motion blur and ghosting test show?

A motion test helps you see whether a moving object stays clear or leaves fuzzy smears, duplicate-looking trails, bright halos or dark inverse-ghosting artifacts. Comparing several speeds and color transitions is more useful than watching one plain moving block.

How to use this improved motion test

Start in full screen and follow the center of the moving target with your eyes rather than staring at one fixed point. Run the same stage at slow, medium and fast speeds. If your monitor offers overdrive or response-time modes, change one setting at a time and repeat the same stage so the comparison is fair.

Practical guide

How to interpret blur, trailing and overshoot

Motion clarity depends on several things at once: refresh rate, pixel transition speed, display persistence, overdrive tuning, browser animation timing and how your eyes track the moving object. The six stages intentionally use different contrast and detail patterns because a panel may look clean on one transition and show artifacts on another.

For a more reliable comparison

What this test cannot confirm

This browser test does not measure a laboratory gray-to-gray response time or motion-picture response time. The frame estimate shown in the tool is only an approximation of browser animation timing and should not be treated as the monitor’s certified refresh rate.
