What has shipped, what has been corrected, and when. Corrections are listed as prominently as new features, because they are more useful.
, First release
Twenty-six tools published: the guided monitor check, dead pixel and stuck pixel tools, nine solid colour pages, a colour picker, backlight bleed, OLED burn-in and its fixer, uniformity, greyscale, near-black, HDR capability, refresh rate, frame rate, ghosting, motion blur, touch and resolution.
The homepage opens with a working test rather than a picture of one: eight standard fields, full screen in one click, arrow keys to step through them.
Published the two reference pages: what a browser cannot detect, and the methodology behind each measurement.
Refresh rate measurement uses the median of frame intervals rather than the mean, so a single stall cannot distort the result.
Wide-gamut swatches ranked by how far each primary actually separates, after measuring that blue separates by only 10 steps of 255 against 117 for green.
Every tool carries a visible limitations block, and a build-time scan fails the release if a forbidden measurement claim appears anywhere in the output.
