Is there a list of manufacturers that actually support DDC? about ddcutil HOT 2 CLOSED

Welcome to the wide world of monitors. If I'd appreciated how much variability there is I doubt I'd have made ddcutil an open source project. LG is particularly problematic and offensive, but offhand I don't believe any of the biggies are much more forthcoming with information. Years ago I came across some public facing documentation re DDC/CI from Benq, which suggests they may be more responsive.

Unfortunately, things are only going to get worse, as the DDC/CI spec has not been updated in years, and there are more and more things, such as PBP that each manufacturer implements in their own way.

I trust you've seen page [Notes on Specific Monitors[(http://www.ddcutil.com/monitor_notes/), though it hasn't kept up with all the information people have reported in the issues.

Re determining what functions your monitor supports, ddcutil probe tries to read (almost) every feature number, so it's a way of testing all but RO features. It and the output of ddcutil capabilities --verbose are a good place to start.

yeah, saw that page. And I did already run both probe and capabilities --verbose, still there are some false positives there, at least in my case.

Damn, that's some really sad news. And yeah, PbP was one of the functions I've been trying to activate here, spent an afternoon on it and got no results so far...

Also! I think I may have hit something weird, my smaller ultrawide 60 feature changed the response on capabilities check. Before, it was reporting DVI-1, DisplayPort-1, DisplayPort-2 (where? there is none), HDMI-1 and HDMI-2... now it's reporting DVI-1 and DVI-2 (there's no DVI-2, like there was none DP-2)
