Dolby Vision For Gaming Went Away

OK that fixed it. Ran the caavo box to receiver then receiver to TV. Had to try a couple different inputs on the receiver because HDR went away. Now I have green checks on everything but Dolby vision which my TV does not support.

Another Nuance came up. Now when streaming with dolby vision Off. Wnen I stream Dolby Content with Netflix through XBOX, within the XBOX settings upon launch of Netflix Dolby vision turns off ALLM in my XBOX and plays Dolby regardless of setting in the XBOX. And launching a game there after it does not turn off dolby vision for gaming or allow dolby vision, nor does it turn back on ALLM. I wanted to try to avoid changing the 4K options everytime I want to do something else.

Okay so apparently it’s something with Dolby Vision gaming as it only happens when i start up a game that uses dolby vision. And when I turn dolby vision gaming off every game works fine. I don’t understand what is happening with dolby vison gaming though as I’ve been using it fine until i just got done playing BF2042.

Honestly the Dolby vision would be the best option until more things are supported that utilize the 3k 120hz rate. Dolby vision will definitely increase the quality of games and apps

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).
