Motion and Ghosting Test
Move high-contrast test objects across the screen at a fixed speed to see how cleanly your display handles motion. Trails behind the object reveal slow pixel response (ghosting), bright or dark halos reveal overdrive overshoot, and the three lanes let you compare speeds side by side. The test starts only when you press Start.
Run a Motion and Ghosting Test
Nothing moves until you press Start. The objects cross the screen once unless you tick Loop.
What to look for
How to Use the Motion & Ghosting Test
- Choose a Speed and Background; keep three lanes for a side-by-side comparison.
- Press Start (and Full screen for the most accurate view).
- Follow an object with your eyes and look at its edges and the area just behind it.
- Use Pause, Replay and Stop as needed; tick Loop to keep it running.
About This Tool
Gamers comparing overdrive settings, reviewers checking response time, and buyers deciding between monitors.
Input: Speed and background · Output: Moving test objects.
Features and Limitations
Features
- Speeds from 240 to 960 pixels per second with optional ½× and 2× lanes.
- Dark, mid-grey and light backgrounds, because ghosting differs between transitions.
- Moves by elapsed time, so speed stays correct on 60, 120 or 240 Hz screens.
- Reduced-motion users get a still frame first and can opt in to animation.
Limitations
- Eye-tracked motion blur is also caused by sample-and-hold displays and is not the same as slow pixels; strobing backlights reduce it.
- Results depend on the browser hitting every frame; close other heavy tabs for a cleaner test.
- This is a visual check, not a measurement of response time in milliseconds.
- Results are computed in your browser; nothing you enter is sent to a server.
Frequently Asked Questions
What is ghosting?
A faint trail behind a moving object caused by pixels that change colour too slowly. It is more visible on dark backgrounds on VA panels.
What is inverse ghosting?
A bright or coloured halo around the object caused by overdrive pushing pixels past their target. Lower the monitor's overdrive setting if you see it.
Why is there a still frame instead of motion?
Your device has “reduce motion” turned on. The tool respects that by default; tick “Animate anyway” to run the moving test.
Should I use full screen?
Yes. Full screen avoids the browser's own rendering of other page parts and makes the objects travel the full width of the display.
