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

Monitor Refresh Delivery Test
Measure a fixed eight-second requestAnimationFrame window with cadence and confidence evidence.
The display appears stuck at the wrong refresh rate or motion is uneven.
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
Set browser zoom to 100% and keep the tab visible.
- 02
Run the fixed eight-second frame pacing capture.
- 03
Compare delivered cadence with the OS display setting.
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.
