Visible RAF intervals are browser-observed timing, not panel Hz, input latency or hardware frame skipping. Long frames exceed 1.8 times the median and 25 ms; spikes exceed 3 times the median.

Animation-frame frequency is a browser estimate, not a direct measurement of the physical display refresh rate.

FAQ

Does this test upload my input?

Core interaction is processed in your browser. Testvexa does not intentionally upload camera or microphone streams.

Can browser limitations affect the result?

Yes. Browsers expose different hardware APIs, so unsupported access is not the same as faulty hardware.
