Note that I've only tested this on a single monitor so far, a Samsung C49RG9, which is the only one I have that supports FreeSync 2 HDR. It would be nice if more people could test it; the compositor side of this is at https://invent.kde.org/plasma/kwin/-/merge_requests/8423
Also worth mentioning is https://gitlab.freedesktop.org/emersion/libdisplay-info/-/issues/51, if anyone wants to help out with figuring out the userspace side of detecting whether or not a given display is actually FreeSync HDR capable. - Xaver
