Browser-visible cadence estimate — not a direct EDID or monitor hardware readout.

Refresh-rate measurement is warming up.

What the estimate means

This page estimates browser-visible display cadence from recent requestAnimationFrame timing. It is not a direct EDID or hardware readout from the monitor.

Why the estimate can differ

Multi-monitor setups, browser scheduling, power-saving modes, variable refresh behavior, and display changes can affect the cadence visible to the page. Hidden-tab timing is discarded and the estimate starts fresh when sampling resumes.
