Hi

If your console is up to date it should work.

Dolby vision is not working with UHD Blue-ray either.

No, this is merely about 4K-content not playing, no matter if there's Dolby Vision or not. Any ideas?

Unless your going to fork over 1000s of dollars to get 1 of the 5 manufacturers that have 2.1. Dolby vision will not work with ALLM.

Performance of hdr10 is not relevant nor is ALLM.

Dolby vision does not work with ALLM. This is confirmed that this is by design. You choose between the higher fidelity of Dolby vision over Game mode ALLM.

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.

Of course the Blu-Ray disks I'm using are UHD and have Dolby Vision.

Dolby Vision is enabled on Xbox One X settings, TV HDMI ports are in Enhanced mode (4:4:4 4K/UHD HDR 60Hz), and the TV test (that can be found inside Xbox menu) returns all green ticks for my Xbox-to-TV connection.

As said, Dolby Vision works with all streaming apps... but not when playing Blu-Ray UHD Dolby Vision disks.
