19 / BROWSER CHECKS
All browser hardware tests
Run focused checks for displays, input devices, audio, cameras, batteries, graphics, storage, and sensors. Save an inspection report locally and export it when you are done.
Display geometry and scaling
Inspect viewport size, screen resolution, pixel ratio, orientation, color depth, and fullscreen behavior.
Open testOnline dead and stuck pixel test for monitors
Cycle solid red, green, blue, white, black, and neutral backgrounds to inspect the panel edge to edge.
Open testBacklight bleed and uniformity
Use black and low-gray fields to inspect bright corners, edge leakage, clouding, and viewing-angle effects.
Open testColor gradients and banding
Inspect grayscale and RGB ramps for abrupt steps, clipping, tint, posterization, and dithering patterns.
Open testOnline monitor refresh-rate and frame-pacing test
Estimate the browser’s animation cadence and inspect frame-time stability with requestAnimationFrame.
Open testOnline keyboard event and rollover test
Record keydown and keyup events, inspect codes, and see how many simultaneous keys the browser receives.
Open testMouse buttons, wheel, and pointer
Verify pointer movement, primary and auxiliary buttons, wheel direction, double clicks, and browser-reported coordinates.
Open testTouch and multi-touch test
Draw with one or more contacts to inspect edge coverage, tracking continuity, contact count, and pointer cancellation.
Open testGamepad buttons and axes
Read connected gamepads, buttons, triggers, stick axes, timestamps, and mapping through the browser Gamepad API.
Open testOnline webcam image and permission test
Open a local camera preview, inspect reported track settings, switch devices, and confirm permission behavior.
Open testOnline microphone level and permission test
Open a local microphone stream, view a live level meter, inspect track settings, and verify stop behavior.
Open testStereo speaker left/right test
Play short, low-level left, right, and centered tones to verify channel routing and obvious distortion.
Open testHeadphone channel and jack test
Check left/right routing, jack detection, balance, intermittent contact, and obvious noise with controlled tones.
Open testGPU and WebGL capability test
Create a local WebGL context, inspect limits and extensions, and run a brief animation workload.
Open testLocal network timing check
Measure repeated requests to this same site for connection, response, transfer, and cache behavior without contacting a third-party speed-test service.
Open testBrowser storage and persistence
Check localStorage, sessionStorage, IndexedDB, storage estimates, and persistent-storage permission for this browser profile.
Open testWindows battery report parser
Parse a locally selected Windows battery-report HTML file for design capacity, full-charge capacity, cycle count, and a simple health ratio.
Open testMotion, orientation, and vibration
Inspect browser motion and orientation events and request a short vibration where the platform allows it.
