Field notes

UFO Test groups 35 browser experiments into Motion, Color, Display, Input, and Advanced sections. Its catalog ranges from frame-rate comparisons and scrolling text to VRR, HDR, chroma subsampling, CRT simulation, scan-out, and mouse-rate checks. The homepage also exposes a refresh-rate detector with FPS and Hz fields, and says tests run at the display’s native refresh rate. The public interface indicates no account or installation is required.
