How to Use the UFO Motion Blur & Ghosting Monitor Test
-
1
Maximize browser window to full screen.
-
2
Observe moving UFO lanes at varying pixel speeds (480 px/s, 960 px/s, 1920 px/s).
-
3
Check for trailing trails (ghosting) or bright halos (inverse ghosting/overshoot).
-
4
Take a tracking photo with your smartphone camera to capture pixel response.
Practical Example & Use Case
Common Real-World Scenario
Adjusting monitor overdrive settings (Fast vs Extreme) to eliminate motion smearing in fast-paced games.
Technical Notes & Limitations
Browser Engine Architecture
Test accuracy depends on your browser vsync synchronization with your monitor refresh rate.
Frequently Asked Questions
What causes ghosting?
Slow pixel response times (grey-to-grey transition delays) leave trailing motion trails.
