See browser-reported screen size, viewport dimensions, pixel ratio and display preferences.
Preview ready. Inspect locally; no automatic pass/fail result.
Values refresh on viewport changes. You can also refresh explicitly and download the current report.
Sizes are browser-reported CSS pixels. devicePixelRatio includes display scaling and may change with zoom; multiplying CSS dimensions is only an estimate, not verified physical resolution. Visual viewport includes pinch zoom where available. Browser/OS text is the reported user-agent, which can be reduced or spoofed. No installed hardware scan or uniquely identifying device IDs are collected.
Reports contain the observations currently shown, not an automatic hardware health verdict. No report is uploaded or saved automatically.
These tools run locally and do not upload your device observations, camera video, microphone input or interaction events. There are no accounts or stored test histories. Camera and microphone access stays under browser permission controls.

No. The browser exposes a limited set of events and reported settings. Inspect or listen to the actual result and compare with other applications if needed. Missing browser events or unavailable features do not prove a hardware failure.
Active input capture, audio playback and camera/microphone tracks are released on Stop, hidden tab, workspace switching and page exit. Pending permission results are ignored and late tracks stopped. Reports download only when explicitly chosen.
