MOTION CLARITY (UFO)
MOTION CLARITY
This page helps compare motion clarity, ghosting, smearing and judder on screens.
It is a practical visual test for monitors, TVs, laptops, phones and tablets.
It is useful for checking gaming modes, overdrive settings and refresh behaviour.
WHO USES IT?
Gamers, monitor buyers, repair checks, TV setup users and display reviewers.
It also helps video makers demonstrate motion blur differences on camera.
COMMON SEARCHES
motion blur test • UFO test • ghosting test
monitor smearing test • display motion clarity • judder test
BASIC STEPS
1) Choose a speed on Page 1.
2) Press START for fullscreen.
3) Follow the UFO with your eyes.
4) Compare blur, trailing and edge clarity.
WHAT TO LOOK FOR
Blur: the UFO stripes become unreadable.
Ghosting: pale or dark duplicate edges follow the UFO.
Judder: movement feels uneven or stepping.
DEVICE TIPS
Use 100% browser zoom and native resolution if possible.
Disable low-power mode for refresh-rate tests.
Try TV game mode, monitor overdrive or high-refresh settings.
QUESTIONS
Is this scientific? It is a visual aid, not a certified lab measurement.
Why px/s? Pixels per second gives repeatable motion speed.
Why UFO stripes? Fine stripes reveal blur and overdrive artifacts quickly.
WHY RESULTS VARY
OLED, LCD, TV processing, response time and refresh rate all affect clarity.
Browser timing, battery saver and screen scaling can also change results.
Compare screens using the same speed, brightness and browser.
MINI BLOG
Sample-and-hold displays can blur during eye tracking.
Overdrive may reduce blur but add ghost edges.
Higher refresh usually improves perceived motion.
