REFRESH RATE VISUALISER
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.

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.
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.

NAVIGATION
Footer links connect HOME, INDEX, PREVIOUS and NEXT.
The internal pager uses the same button names on every page.
PRIMARY PHRASE
refresh rate test is the main search phrase for Teletext-Tools page 793.
The page offers working sweep, wheel and strobe visual patterns.
CODE HIGHLIGHT
<title> names Hz visualiser and cadence meter.
canonical points to /refresh-rate-test/.
SEARCH INTENT
Users want a quick way to check whether high-refresh motion is working.
Page 1 answers that intent with controls, preview, HUD and fullscreen launch.
HZ TERMS
Hz test, 120Hz test and 144Hz test are important related phrases.
Screen refresh checker and refresh visualizer support broader search intent.
CODE HIGHLIGHT
estimateHz() uses frame-time samples to choose likely refresh buckets.
drawHUD() prints CADENCE, EST and JITTER on the canvas.
READABILITY
SEO text is not squeezed beside the live canvas and controls.
Large internal panels keep help copy readable on desktop, tablet and mobile.
PATTERN FEATURES
SWEEP bars show stepping, judder and smoothness quickly.
WHEEL mode reveals aliasing; STROBE mode makes strip motion obvious.
CODE HIGHLIGHT
drawBars() renders sweep bars and a scan line.
drawWagon() renders spokes for wheel-style cadence checks.
drawStrobe() renders strong strip motion for judder checks.
USER BENEFIT
Different patterns make different refresh and cadence problems easier to see.
The SPEED slider lets users make motion calmer or more demanding.
FULLSCREEN VALUE
Fullscreen mode removes page UI and gives a cleaner cadence reading.
The fullscreen layer remains easy to exit with ESC, tap or click.
CODE HIGHLIGHT
fx is the fixed fullscreen test layer.
fxCatch catches tap and click exits above the fullscreen canvas.
INTERNAL LINKING
Advanced Display Tools links this test with FPS and motion tools.
Footer PREVIOUS goes to P792 and NEXT goes to P794.
