I have The Frame (2020) + Sonos Arc setup
I saw elsewhere that this TV does not support Dolby Atmos, but I do see something in the menu.
The TV supports Dolby Digital and Dolby Atmos via HDMI eARC, but not DTS.
I have a SONOS ARC and 2020 65" frame TV and I am unable to select Dolby Atmos. The field is always greyed out and cannot select it. Any suggestions?
