WHAT THIS TOOL IS FOR

REFRESH RATE TEST

This refresh rate test uses motion patterns and browser frame cadence.

It helps visualise whether motion looks closer to 60Hz, 90Hz, 120Hz or higher.

The HUD estimates cadence from frame timing, not hidden hardware APIs.

WHO USES IT?

Gamers, display reviewers, phone users, developers and monitor buyers.

Use it after changing battery mode, browser, gaming mode or refresh settings.

HELP
HOW TO USE

BASIC STEPS

1) Pick SWEEP, WHEEL or STROBE.

2) Press START for fullscreen.

3) Watch CADENCE, EST and JITTER.

4) Exit with ESC or tap/click.

PATTERN GUIDE

SWEEP: easiest for seeing smoothness and stepping.

WHEEL: reveals aliasing and uneven cadence.

STROBE: strong strip motion for spotting judder.

DEVICE GUIDANCE

Disable low-power mode before testing high refresh screens.

Enable high refresh in OS/browser settings where available.

Close heavy tabs and test more than one browser.

FAQ
CADENCE AND JITTER

QUESTIONS

Is it exact Hz? It estimates browser rendering cadence.

Why stuck at 60? Battery saver, browser caps or OS settings may limit refresh.

Best pattern? SWEEP is best for most quick checks.

WHAT JITTER MEANS

Jitter is uneven frame timing.

Low jitter usually feels smoother than a higher but unstable cadence.

Large jitter can look like judder, skipped frames or uneven movement.

MINI BLOG

Higher refresh can make motion look smoother.

Frame cadence is just as important as the Hz label.

Power modes often cap phone and laptop refresh.
