Xbox One X 4K not recognised after update and Dolby Atmos/DTS X not working

MNKhawaja · Aug 20, 2022

Hi guys, my Xbox One X updated itself on 22 July 2022 and since then 4K has stopped working on it, as has Dolby Atmos and DTS X and the resolutiion is fixed at a 640 x 480 resolution.

I have a Denon X4700H receiver and a 4K Sony 9000 series TV.

I have tried hard resetting it, resetting it from the system software (but keeping existing software and applications), tried swapping HDMI cables, tried a different HDMI port on my receiver.

The only semi-fix so far was disabling 'auto-detect' under the video fidelity & overscan settings and selecting HDMI and then going back to the display resolution and manually selecting 1440; however it still does not let me apply 4K under display options and says my TV doesn't support 4k! Hence I am unable to get 4k gaming (or HDR 10).

Dolby Atmos and DTS X still doesn't work.

Any idea what the fix is? Thanks.

Hi Georges, still doesn't work after the offline update. All that's changed is that the last update date under system settings now shows as a random 1600 Gregorian year update! ... still no Dolby Atmos / DTS X sound and no 4K gaming.

My Xbox One X is connected to my receiver. When I try to setup Atmos in the audio settings Xbox One X says that my receiver, Denon AVR-4300H, does not have Atmos capability. I am only allowed to choose DTS for the bitstream sound output. Atmos works fine
with my Samsung 4K player so I know it is an Xbox One X issue.

The Dolby App does not give any error until I try to view the demo videos where it flashes, "you are not viewing this video on Dolby Atmos." It plays the demo video on DTS instead.

I'm having the same exact issue.

***UPDATE***

I finally got Dolby Atmos to work!!! Under "Settings, Display & Sound, Volume, Setup TV & AV Control, Audio" I had to change the default "Stereo" setting to "Surround Sound." The Xbox One X had to reboot to accept/change the setting. Once it rebooted Dolby
Atmos was working. It is interesting that the main control will be under the volume settings instead of audio output. You would think the system will be smart enough to activate surround sound when you are choosing Dolby Atmos to bitstream.

Hopefully this "difficult to find" change of setting will work for others who are having Dolby Atmos issues.
