Display geometry and scaling

Inspect viewport size, screen resolution, pixel ratio, orientation, color depth, and fullscreen behavior.

Cycle solid red, green, blue, white, black, and neutral backgrounds to inspect the panel edge to edge.

Inspect grayscale and RGB ramps for abrupt steps, clipping, tint, posterization, and dithering patterns.

Estimate the browser’s animation cadence and inspect frame-time stability with requestAnimationFrame.

Create a local WebGL context, inspect limits and extensions, and run a brief animation workload.

Check localStorage, sessionStorage, IndexedDB, storage estimates, and persistent-storage permission for this browser profile.

Open a local camera preview, inspect reported track settings, switch devices, and confirm permission behavior.

Open a local microphone stream, view a live level meter, inspect track settings, and verify stop behavior.

Check left/right routing, jack detection, balance, intermittent contact, and obvious noise with controlled tones.

Record keydown and keyup events, inspect codes, and see how many simultaneous keys the browser receives.

Verify pointer movement, primary and auxiliary buttons, wheel direction, double clicks, and browser-reported coordinates.
