Trailing images are observed visually. The page cannot measure gray-to-gray panel response time or force the display into variable-refresh-rate mode.
Trails and bright inverse trails are visual observations. The animation cannot calculate physical gray-to-gray response time.
Use a stable refresh mode. Camera exposure and pursuit technique can introduce artifacts into recorded comparisons.
VRR observation varies browser workload on a dark background. Whether VRR activates depends on operating-system, driver, browser and monitor settings.
It provides a repeatable moving pattern. You judge the balance between ordinary trailing and overshoot on your own panel and refresh mode.
Start the moving pattern and follow it with your eyes. Compare speeds or record with a camera. Stop the animation when finished.
