How to run this check
Start the pattern and follow it with your eyes. Compare speeds and monitor overdrive settings.
Understand the result
PASS describes a received signal or your recorded observation. WARNING calls for another check. USER REVIEW REQUIRED means a measurement alone cannot decide. An unavailable API or denied permission does not establish hardware failure.
What this cannot tell you
Eye tracking, rendering and pixel response all affect visible trails; no response-time value is measured.
If something seems wrong
Compare moderate overdrive modes. Very aggressive overdrive can produce inverse trails.

No. It records behavior observed in this browser session. Intermittent faults, internal components and operating-system restrictions need further investigation. See our methodology.
