Please try to check your TV settings. Maybe your TV went to a dolby vision mode (and not back) and does not support VRR and ALLM in this mode. If the xbox does not show up the features, the TV does not report those features back.any idea how to downgrade the xbox series firmware?
the dolby vision update makes me loss
1. ALLM
2. VRR
both of them greyed out. Xbox series S, LG CX.
I had to deactivate DV on my xbox because else my x900h TV does not have a game-mode and the lag makes games unplayable.
