What this tells you

Refresh rate is estimated from browser animation frames. Resolution uses the reported device pixel ratio when available.

Understand your results and improve your setup

A good test should not stop at a score. Use these practical checks to understand what the browser measured, what can affect the result, and what to change before your next call, stream or gaming session.

Visual inspection

Full-screen colours and patterns help reveal stuck pixels, obvious uniformity issues, banding or contamination. Clean the display first so dust is not mistaken for a pixel defect.

Not a calibration tool

Colour accuracy, luminance and contrast require a colorimeter for calibrated numerical results.

Why CamMicGo goes further

✓ Private by design: tests and recordings are processed locally in your browser whenever possible.
✓ Multilingual by design: the same diagnostics and explanations are available across CamMicGo languages.
✓ Practical diagnostics: CamMicGo focuses on repeatable browser measurements and explains their limits instead of presenting them as laboratory certification.
