night mode and dolby vision not working

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.

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.

It's not an issue that requires resolving. It's just a simple reminder that Dolby Vision increases input lag. If it feels like the input lag is unbearable, just disable Dolby Vision for Gaming in the video modes menu.

Hi

If your console is up to date it should work.

Hi there SorrowSeer,

Thanks for the update on the inquiry on the Dolby Vision. To start enjoying this feature today, you need a TV that supports
the latest version of Dolby Vision.

To setup this feature, first check if you have a compatible TV by going on your Xbox to the 4K TV Details page under Settings. You can also check the full list of supported TVs here.

• Next enable Dolby Vision on your console by navigating to Settings -> Display and sound -> Video output -> Video modes -> Allow Dolby Vision.

Hope this helps.
