DisplayDNA keeps monitor evidence byte-close
A local-first beta for inspecting display layouts, EDID data, and profile changes across macOS, Windows, and Linux.
- For
- People investigating monitor identity, profile changes, or display layouts
- Worth noticing
- The page distinguishes live hardware verification from fixture-tested collectors, and notes that native Windows hardware validation is still pending.
Field notes
The workflow separates a display's reported capabilities from its active settings, then compares saved snapshots against a baseline. The demo shows a 60 Hz-to-30 Hz settings observation and a separate profile-byte difference, explicitly treating both as evidence to inspect rather than proof of intent. Collectors are local-first; the page says they do not capture screen contents or upload display data. Coverage is uneven: macOS hardware is verified, Windows hardware validation is pending, and Wayland geometry is unavailable.
