Separate browser-delivered frame cadence from visual observations such as trailing, uniformity or gamma match.

HDR and Wide Color Gamut Browser Test
Inspect browser-reported dynamic range and gamut media queries with SDR/WCG reference fields.
HDR or wide-gamut content is not being exposed to the browser.
This focused entry uses the shared Display protocol. The measurement logic and Evidence version remain identical to the complete lab.
Remove the easiest false alarms first.
01
Set browser zoom to 100%, keep the tab visible and close animated or high-load windows.
02
Confirm the operating-system refresh, HDR and scaling settings before comparing results.
03
Change only one display setting per run and keep room light stable for visual references.
Run one repeatable protocol.
- 01
Verify the operating system HDR and monitor mode.
- 02
Inspect browser-reported gamut and dynamic-range capability.
- 03
Compare the SDR and wide-gamut reference without treating it as calibration.
Evidence the result should expose.

Separate observed, review and inconclusive.
Repeat long-frame or visual artifacts after checking zoom, power mode, duplicated displays and the selected monitor mode.
A browser cannot certify panel response time, PWM, peak brightness, gamut volume or calibrated gamma without external instruments.
Start with the likely path, then retest.
