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.
- FPS TestMeasure browser animation FPS, frame time, long frames, and stalls.
- Monitor Ghosting Test — Motion Trails & Inverse GhostingInspect moving edges for trails, inverse trails, smearing, or visible blur.
- Frame Skipping TestInvestigate browser timing and a visual sequence for possible skipped frames.
- Pitch DetectorEstimate fundamental pitch and note from explicit local microphone input.
- Screen Tearing TestUse moving patterns to look for visible horizontal tearing or uneven motion.
- Tone GeneratorGenerate bounded tones and a controlled frequency sweep.
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.
Used Device First Check
Run a browser-visible first pass across common input, display, camera, and audio functions on a laptop, desktop, all-in-one, or display setup.

Check browser-visible input and display timing before a gaming or controller setup session.

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 methodologyDirect 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
