graphics/drm-kmod-g20190710 doesn't recognize HDMI head on RV730 XT Radeon HD 4670 (xrandr reports HDMI as disconnected)
while graphics/drm-legacy-kmod-g20191217 works fine

graphics/drm-kmod is just a meta-port that pulls in the correct drm-*-kmod, can you list the version of the installed drm-fbsd12.0-kmod please?
as well as all variants of ports in head
in addition, I've checked it on 13.0-CURRENT and ports head, so, all variants except legacy behave the same - after drm initialization, HDMI display blanks (though, it doesn't show "No signal" message in that state)
