A browser-based suite for checking frame rate, refresh rate, motion blur, ghosting, dead pixels, mouse polling, input lag, and other display behaviour.

Landing page captured for the 2026-09-01 issue.

Field notes

The suite combines numeric and visual diagnostics: requestAnimationFrame-based frame measurement sits alongside moving-object, colour-bar, and full-screen colour-cycle tests. Its coverage extends beyond FPS into refresh rate, ghosting, resolution, device-pixel ratio, colour depth, mouse polling, and input latency. The listed UFO test spans 120–3840 pixels per second, while the polling test covers rates from 125 to 8000 Hz.
