XBOX Summer Game Fest Show Dynamic Background

At this time, dynamic backgrounds are only available on the Series S/X and can't be customized. If the video you saw was done on a One, then the person doing it is doing something that violates the terms of service.

If you are on a Series S/X, when you go to settings and change your background, there's a section for dynamic backgrounds.

Thanks for replying. When I go to "Settings > General > Personalization > My background", and then put in my passcode, the screen is grey. I can view images in capture, but I have not found a way to view the current background. There is a list of 5 options: Solid Colors, Custom Image, Dynamic Backgrounds, Show selected game art, and Restore Default Background. Is there something I am missing?

Hello, SapphireTheRose. Thanks for reaching out. I'm an Independent Advisor and Microsoft Xbox user. I'll be glad to help you out.

Unfortunately, there's no way to create or add dynamic backgrounds to Xbox yet. The only ones available are the ones Microsoft add. But it would be very nice to be able to create or buy dynamic backgrounds.
