Field notes
The test directory groups checks into display performance, pixel and uniformity, motion, and mouse or keyboard input. The accompanying guides give practical comparison advice, including using a short color sequence for a suspicious pixel and keeping speed and background consistent when inspecting motion trails. Timing results are framed as browser-based estimates, not direct measurements of a monitor’s panel.
