Inspect your display manually with solid white, black, red, green, blue and grey patterns.
Preview ready. Inspect locally; no automatic pass/fail result.
Inspect the pattern visually. Fullscreen expands it; Escape or Exit fullscreen returns. Overlay controls can move to expose covered pixels.
This is a manual visual inspection. Solid colours can help you notice stuck/dead pixels, but the browser cannot inspect your physical panel or certify it is defect-free. Fullscreen is optional and may be unavailable. Use Next pattern and move the small overlay controls to inspect the area they cover. No automatic flashing or system brightness changes.
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.
