Oddly enough, the dashboard of Microsoft's Xbox Series X is not 4K, this is despite being a console released with a focus on actual gaming in 4K resolution.

The dashboards of the Xbox Series X and S and all their accompanying UI elements have been rendering at 1080p resolution since the consoles' launch.

Now, finally, after continuous complaints from the Xbox gaming community, Microsoft has announced that a new 4K resolution dashboard interface for the Xbox Series X is in testing.

Microsoft's Xbox testing team states what 4K brings to the table:

This change means Home, Guide, and other areas of the UI will be displayed in a higher native resolution for increased sharpness and text readability.

It is important to note that the improved resolution will apparently not demand more resources from the console.
