The monitors, connections and Macs Candela has been used on, one row per monitor and connection. Rows come from hardware reports and from the maintainers' own displays; the columns match what the report form asks for, so a report becomes a row without translation.
Every row is self-reported: the person who filed it observed the behaviour on their own panel. Maintainers do not re-verify rows they cannot reproduce. If your monitor is here and behaves differently for you, that difference is exactly what a report is for.
The capability columns say what actually changed the display, not what the
spec sheet promises. yes means the control worked, no means it did
nothing, n/a means the monitor declares that it has no such control, and
not tried means nobody has checked yet. DDC reads is the "Reading values
back" line on the display's Diagnostics page: a monitor that answers reads
lets Candela confirm what it set, and one that does not is driven blind, with
Candela remembering the last value it wrote.
