you can find on this page a lot of help with black screen Problems:

Thats not directly for your problem, but maybe you can try some solution and ist help

Sorry for hijacking your thread, but I can not find an option to start/create a new thread for an unrelated issue I'm having. Can someone point me in the right direction?

Edit: I was able to finally locate the option to make a new post. Sorry about this.

thanks for the answer but i just had to change the soundbar from optical to HDMI mode.

dolby atmos is now working but now i dont have HDR.

Don't plug the hdmi in the ARC port, try just plugging it straight into a hdmi port on the TV.

It seems that your TV supports Audio Return Channel (ARC). However, on the TV's specification page I don't see if it supports Dolby Atmos through ARC.

If your TV is capable to send Dolby Atmos via ARC, you'd connect your Xbox to a 4K capable HDMI port OTHER than the HDMI ARC port on your TV.

You will then get 4K resolution on the TV screen, and the TV would "forward" audio via the Audio Return Channel to the sound bar. If supported, this will then be Dolby Atmos.

It seems that the Soundbar doesn't support 4K pass through. So either you would need a new TV that supports Dolby Atmos via ARC, or a new soundbar or AV receiver that supports 4K video.
