Refresh Rate Test

Measure your browser-visible display refresh rate and compare it with the refresh mode you expect from your monitor.

How to interpret refresh rate readings

The measured rate reflects what the browser is seeing from your current display path, not just the label printed on the monitor box.

A lower-than-expected number can still come from OS settings, cables, adapters, mirrored displays, or browser frame caps.

What to try next if 144Hz is not showing

Check Windows, macOS, or GPU control panel refresh settings first, then verify cable and port bandwidth before assuming the panel is limited.

Run the monitor guide route if you need a step-by-step checklist for 144Hz and higher display modes.
