Test matrix

What to test and what a pass actually tells you

Run the test closest to the symptom. A passing result narrows the diagnosis; it does not certify the entire device.

Touchscreen TestDraw on the screen to verify touch/pointer coverage.

Use the result to narrow the next branch; browser visibility is intentionally limited to the subsystem exposed by the current API.

→
Multi-Touch TestTrack multiple simultaneous touch points.

Use the result to narrow the next branch; browser visibility is intentionally limited to the subsystem exposed by the current API.

→
Dead Pixel TestShow solid colors full-screen so you can visually inspect for dead or stuck pixels.

Use the result as a visual/timing reference. It cannot certify panel electronics or cable signal integrity by itself.

→
Screen Resolution TestShow browser viewport, screen dimensions, and device pixel ratio.

Use the result as a visual/timing reference. It cannot certify panel electronics or cable signal integrity by itself.

→
Keyboard TestPress keys and verify that the browser receives the expected keyboard events.

A pass proves browser input events are arriving; app/game mappings, profiles and accessibility settings move higher on the list.

→
Mouse Drag TestVerify pointer down, movement, and release during dragging.

A pass proves browser input events are arriving; app/game mappings, profiles and accessibility settings move higher on the list.

→
Webcam TestOpen your webcam locally to verify that the browser can access and display a live camera stream.

A pass proves this browser received live camera frames; app selection, permissions or capture mode become more important if one app still fails.

→
Microphone TestCheck whether your browser can detect your microphone and receive live audio.

A pass proves the selected input delivered audio into this browser session; app routing or processing becomes the next branch.

→
Left Right Speaker TestPlay left and right channel tones separately.

A pass proves browser playback reaches the selected output path; it does not prove every codec, surround or app-specific route.

→
Browser Battery StatusShow charging state and charge level when the browser exposes the Battery Status API.

Use the result to narrow the next branch; browser visibility is intentionally limited to the subsystem exposed by the current API.

Model-specific problems

Start with the symptom people actually search for

These paths combine this model's documented limits with live evidence, instead of copying a generic troubleshooting checklist.

HP Spectre x360 14 dock charges but monitor has no signalHP lists two Thunderbolt 4 USB-C ports with USB Power Delivery and DisplayPort 1.4. Charging proves only the power path, so a dock that powers the Spectre but has no monitor output still needs the video-capable cable, dock topology, monitor input and DisplayPort path checked separately.

Evidence handoff

If the browser cannot reach the suspected subsystem

Keep the browser result as one observation, then move to the operating system or manufacturer diagnostic that can see the protected hardware state. Do not interpret an unsupported browser API as a failed component.
