Xbox Series X does not show "Allow Dolby Vision" or "Dolby Vision for Gaming" with LG C1...

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 I have a Xbox series x with a Dolby vision compatible tv also will the allow Dolby vision playback selected in settings on and it still only displays in HDR only when playing 4k blu rays ? I have set it 4k 60hz and the games display in Dolby vision plus streaming apps but not 4k disc playback! Is this correct that the xbox series can’t do this ?

I had the exact same problem which didn't start until today, and I use my Xbox Series X every day..

Starting today, running any game would show me a screen like the op showed.

I turned off Dolby Vision on my LG 55C2 like Jesse Mass suggested (THANK YOU!) and that completely fixed the problem.

With regards to Dolby Vision...

So it's either a TV update that went through (current software version 03.33.65) and changed something (but I didn't notice a recent update), or the Xbox changed something (though the last Xbox update was over a month ago).

So I turned off Dolby Vision in the Xbox's video settings and now everything works fine (except for no Dolby Vision).

SOLVED: Turns out my pi-hole was blocking some sites needed for the Xbox to show the Dolby Vision options. The Dolby Vision options in settings appeared once I disabled the pi-hole. I also had a problem where Xbox Assist would not launch, and it now launches with the pi-hole disabled. So this appears to have been a network issue on my end. Hopefully this will help anyone having similar issues in the future.

I have a XBOX One X connected to an OLED LG C8. If I use the Netflix app on XBOX One X then the LG will display Dolby Vision. So I know that it is passing. But If I use a 4K Bluray that has Dolby Vision, the player will only output HDR。Blu-ray
playback is already up to date.
