Advanced Display Lab
Advanced browser-based diagnostic tests for OLED, HDR, Mini-LED, local dimming, and modern high-performance displays. Inspect near-black shadow detail, backlight haloing, wide color gamuts, and persistence artifacts.
Browser-Observed Display Signals
Guided Diagnostic Workflows
Essential health audit for new screens.
Refresh rate, ghosting, overdrive overshoot, and frame pacing.
Near-black detail, 5% gray banding, retention, and burn-in.
Highlight clipping, black level, and Display-P3 gamut.
Local dimming, haloing, starfields, and subtitle blooming.
1:1 pixel mapping, gamma curve, and color neutrality.
OS scaling text clarity, battery frame pacing, and bleed.
Overscan, 1:1 pixel mapping, and chroma 4:4:4 subsampling.
Exhaustive, profile-aware master diagnostic workflow.
OLED Display Lab
