Diagnose a problem

Start with what you notice

Choose the closest symptom; these curated routes suggest a test without pretending to diagnose hardware.

Common diagnostics

Start with these tests

Quick paths into common browser-visible display, motion, and audio checks.

Guided checks

Complete one real task

Move through several specialist tests with neutral observations and a local-only report. A check never turns browser evidence into a hardware health score.

What a browser test can tell you

Evidence, not a universal health verdict

DeviceMetrik names the kind of evidence each instrument can produce and keeps unsupported hardware conclusions out of the result.

Read the measurement methodology

Direct browser input

Keyboard, mouse, gamepad, and touch tools read browser-exposed events or state—not electrical switches, firmware, or raw USB traffic.

Browser-observed timing

FPS, refresh, event-rate, DPI, and reaction tools estimate what reaches or runs in the browser—not laboratory hardware timing.

Visual and listening checks

Controlled patterns or signals help you inspect what you see or hear. Your observation is not an automatic hardware diagnosis.

Camera and microphone capability

Media tools request only the needed permission after Start and process locally. They do not upload media or certify device quality.
