Testufo

What is it?

testufo.com runs pursuit-camera style and other visual tests for refresh rate, motion blur and related display behavior—useful for checking whether a stated Hz mode is actually active.

How to play

• Open a test pattern matching your goal (Hz, blur, etc.)
• Follow on-screen instructions; fullscreen recommended
• Compare results across monitors if you have more than one
• Use a direct connection and correct OS refresh settings for fair tests
