Regarding Dolby Vision and how Series X handles it's HDMI port (LG 9 Series)

No, unfortunately, one cannot speak of clarity in this case, because I have experienced the exact opposite case.

I own the LG C1 and the LG C2, and the handshake problems have NEVER occurred in over a year of use on the C1! Instead, however, they keep coming back with the C2 on the same Xbox Series X console. When switching this console back to the C1, the same picture again, NEVER! LG C1 and LG C2 both support Dolby Vision (for gaming). Before testing the LG C2 with one / my Series X, I had never heard of the handshake issue with Dolby Vision. Besides, the LG C2 works very well, but the Dolby Vision handshake in games can hardly be tested on other devices, because the PS5 does not support this feature and other devices are at least unknown to me.

Hi,

unfortunately the series x doesnt have an optical audio out port so that is not an option - and that also doesnt solve the issue which is specific to dolby atmos.

So according to the manual for the panasonic soundbar i need to run two hdmi cables from the xbox - one to the tv for dolby vision/ALLM and then a second one to the soundbar for the sound

Obviously theres only one HDMI out socket on the series x so i assume this is not possible?

I just had this same issue on my LG G3 TV. I went in and turned off Dolby Vision on the XBOX Series X and that fixed the issue. HDR works fine. This seems like a issue with a recent update.

I had the same issue and figured it out. My LG TV had the HDMI port I was using for my Xbox series X set to an audio input format of PCM (like my PS5 in the next HDMI slot). I changed it from PCM to bitstream and on the Xbox settings the Dolby Atmos and 5.1/7.1 options returned.

I've never had an issue with

my Onkyo receiver it's actually fixed my issue with my series x and lg c1 issue and my Onkyo receiver came out in 2017 and it supports 4k hdr and Dolby vision. All work perfect. The issue is a Xbox issue as my 360 and my ps3 and my series s never had an issue directly to the tv it's only with the series x and it's strange that you blame the tv when all other devices work but the series x.
