Specialized utilities to inspect browser hardware capabilities, calculate pixel density, compare display dimensions, and generate test patterns.
Query browser-detected screen parameters, unmasked GPU hardware, WebGL 2.0 / WebGPU support, HDR, and live frame rates.
Probe live browser display and platform APIs against hardware capability boundaries.
Interactive side-by-side display size overlay, pixel density (PPI) comparison, aspect ratio GCD math, and optimal viewing distance.
Generate 12 specialized calibration patterns including SMPTE color bars, crosshatch, dot grid, zone plate, and gradient ramps.
Detailed screen resolution analysis, display scaling ratio (DPR), pixel density, visual size comparisons, and viewing distance guidance.
Select what visual defect you are observing (dead pixels, strange colors, dark shadows, blurry text) to generate a targeted test sequence.
Record voice notes and audio clips in browser memory with pause, resume, instant playback, and local download.
Review recorded observations, inspect dropped pixel defect coordinates, review hardware profiles, and export or print inspection documentation.
