Dolby Vision playback

[DMD]

I have demos in Doly Vision, the audio track is present, but the video is black.
The HiMedia q10 Pro is connected with the LG 65B6, perhaps it is the TV that is not updated to Dolby Vision.

Thanks

Q5/Q10 Pro do support Dolby Vision because Dolby will not issue a licence for media players.

This puts me in trouble as one of the first films he released in Doby Vision is Spectre.
