Can we get a Dolby Vision toggle for certain games

Hello,



Welcome to the Xbox Community Forum. Thank you for sharing your concern with us today and we hope that all is well. I can see that you need assistance in enabling Dolby True HD. Let me see how I can assist you with this concern.

Dolby Vision on Xbox

Dolby Vision on Xbox | Xbox Support

The Xbox console supports Dolby Vision technology, which allows you to see games and media with a greater degree of brightness, contrast, and color.

Things to keep in mind:

• On Xbox Series X|S, Dolby Vision is available for streaming media apps and playing games.
  
• On Xbox One X and Xbox One S, Dolby Vision is available for streaming media apps only.
  
• Dolby Vision is not supported on the original Xbox One.
  
• Dolby Vision is not available for media playback via Blu-ray.
  

Enable Dolby Vision for games

To enable Dolby Vision, press the Xbox button  to open the guide, and then go to Settings > General > TV & display options > Video modes > Dolby Vision for Gaming

Troubleshoot Dolby Vision

Note Consult your TV manufacturer for Dolby Vision gaming compatibility and firmware updates.

If your 4K@120Hz TV supports Dolby Vision gaming at 4K@60Hz but not 4K@120Hz, follow this guidance for Dolby Vision gaming, and reach out to your TV manufacturer.

Gaming in Dolby Vision:

1. Press the Xbox button  to open the guide and go to Settings > General > TV & Display options.
   
2. Set Resolution to 4K.
   
3. Set Refresh Rate to 60Hz.
   

Gaming in 120fps:

1. Press the Xbox button  to open the guide and go to Settings > General > TV & Display options.
   
2. Set Resolution to 4K.
   
3. Set Refresh Rate to 120Hz.
   

If your TV has the latest firmware and you’re experiencing display latency or input lag while gaming in Dolby Vision, disable Dolby Vision while gaming and reach out to your TV manufacturer.

To disable Dolby Vision, press the Xbox button  to open the guide, and then go to Settings > General > TV & display options > Video modes > Allow Dolby Vision > Off.

If your TV or monitor displays a blank screen after enabling Dolby Vision, unplug and reattach the HDMI cable. If you still see a blank screen, reboot your Xbox console:

1. Press and hold the Xbox button  on your controller.
   
2. Choose Turn off console or Restart console > Restart.
   

Let us know the result and we will get back to you as soon as we can. We may recommend further troubleshooting steps once we have received your answers to the above questions.

The system supports Dolby Vision in certain streaming apps like Netflix, Disney +, and Vudu, but it's not yet supporting playback of 4k discs with Dolby Vision through the blu-ray app. Hopefully they will eventually patch an update to do so. But currently,
it does NOT.

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

Without knowing the BluRays your trying to watch there isnt much we can do.

I do know that not all UHD BluRays support Dolby Vision, they all support HDR10 (as its a free to use license) but Dolby Vision costs the movie studios to use. it.

Perhaps look at the back of the UHD box and see if it mentions Dolby Vision, if not its probably only using HDR10.

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.
