    4K 120Hz + ALLM + VRR breaks ALLM, turning off VRR fixes it but then breaks Dolby Atmos


    I have reported these issues many times since last year. No response from Microsoft and has not been fixed. I wish there was a way to see if our issues were acknowledged or not. It feels like they go into a black hole. I've posted here as well and other people said they had the same issues so I know it's not just me.

    With 4k 120Hz + ALLM + VRR enabled, then Xbox turns ALLM on when I'm on the dashboard and when I'm in Disney+, Hulu, YouTube, Movies & TV, Netflix AND when I'm in games. This then disables picture mode processing such as 24Hz support. Turning off VRR fixed this issue, however then when I navigate to the dashboard or watch videos in YouTube, the audio is all garbled unless I turn off Dolby Atmos.

    This wasn't an issue when I first got my Xbox Series X, but then started after an update in mid to late November 2020. There have been multiple firmware updates for my LG OLED C9 and many updates to Xbox since November 2020 and it's still an issue despite reporting it many times.

    Please fix this, or acknowledge it or something. If Xbox Series X supports the latest home entertainment features, but they don't work or fix them, they are useless.

    Xbox Series X Allow Dolby Vision/Dolby for Gaming and Allow Auto Low Latency Mode

    Hi thanks I have played with this for sometime, There is a green check mark by ALLM. ALLM is supported by a 2.0. 2.1 hdmi only exception is no 60@120hz.

    HDR10 is also has a green check without a 2.1 input there are no limitations as my input during game indicate HDR10 is working. I can do this by checking my inputrs throught TV settings (Auto select for 2.0 enables ALLM Feature on My TV). Dolby Vision for games does not work when ALLM is enabled.

    Everything is green on 4K EXCEPT for 120hz because of the lack of 2.1 port. When I turn off ALLM through XBOX setting Dolby vision works.

    How do I find the motion enhancement/anti judder option in my TV?

    Lol... Thanks but they don't know. It seems that when I disable VRR and ALLM from the TVs settings, it automatically unlocks the motion enhancement options. But if I enable VRR and/or ALLM either from my Xbox or the TV itself, then the motion enhancement setting disappears.

    Isn't VRR supposed to unlock higher frame rates?

    This is really confusing 🤣

    Xbox One X connectivity to my Monitor

    Xbox One X supports 1440P and 120Hz or 4K and
    60Hz. By attaching HDMI 2.1 or 2K@120 via HDMI 2.0. The cable will output just 1440P@120Hz only, in the end, this is a monitor that most suitable for PCs. Check the Video Output settings and tweak it accordingly. Your monitor, unfortunately, doesn't support
    ALLM or VRR.

    Good luck!

    Xbox Series X Allow Dolby Vision/Dolby for Gaming and Allow Auto Low Latency Mode

    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.

    Allow variable refresh rate greyed out

    my bad, 65NANO95UNA
    Well, the LG page of that particular model makes no mention of VRR which would usually indicate it is not a feature:

    Edit: I have been looking around and none of the other NANO95 models have VRR either...the have ALLM (Auto low Latency Mode), not VRR
