im trying to play video using 5kplayer from imac sierra 2017 27inch to tv via hdmi, i have desktop mirrored which is working fine.
however when i play any video with 5kplayer the video is black (audio works)on my tv.
Quicktime, youtube and other players mirror the video fine,
any suggestions, i dont wish to use tv as extended monitor or as primary desktop
