If your console is up to date it should work.

How to use Dolby Vision HDR on Xbox One:

Dolby vision is not 4k it is a software enhancement for the HDR aspect so not having it is not a major issue, but if you like to have all the green checks you need to look for high end tv's that support Dolby Vision like LG Oleds and Vizio Oleds

I am using Pioneer VSX-832 audio recevier, as far as I am aware it is updated already. Microsoft claims both can be turned on, which I can, but then Dolby Vision only works and hdr 10 don't. Also, Dolby Vision only works correctly when only Dolby Vision
is turned on.

On your console display settings, is HDR and Dolby Vision enabled?

Most people that get flickers on the screen (both playing or only on the dashboard) with Dolby Vision on is because both HDR and Dolby Vision are enabled at the same time.

Just try to turn HDR off and see if it solves your problem. If it does, unfortunately we will not be able to do much about it. It's a bug reported by some people and the only option would be use HDR or Dolby Vision, not both at the same time

But know that HDR and Dolby Vision are two different, incompatible, color schemes for UHD TV sets. Most support HDR but some support Dolby Vision. There are a couple of websites I check for this kind of tech talk but I don't think we csn post links to
outside sites here. Most UHD tvs support HDR 10 but I've heard Dolby Vision is better. Xbox One does not support Dolby Vision, just HDR 10.
