I have my LG OLED 65B7A connected to a Sonos Arc soundbar via the HDMI-Arc port on my TV. Will the TV pass an Atmos signal to the Arc speaker? Also, does this model TV support DD+? Thanks!
If Dolby Digital Plus isn't mentioned in the TV's 'User Manual' (with a registered trade mark/logo) then you're out of luck...Do most tv's older than 2016 not support this? (I have a Sony Bravia HX800 from 2010 that seems to only support Dolby Digital, and passing through 2.0 PCM in the case of Dolby Digital Plus...
From memory, the UH770 series doesn't support Atmos, either natively or through passthrough.I have 2016 LG 49UH770V model. It has Dolby Digital Plus option under DTV settings so I assume that this codec is implemented in firmware (5.60.25). Unfortunatelly I do not get Atmos from any internall apps (Netflix, Amazon Prime nor Apple TV). My soundbar (JBL 5.0 Multibeam) plays Atmos when sent from XBOX ONE X (Netflix). I asked LG about it and still waiting for their reply.
Indeed, LG Support replied:From memory, the UH770 series doesn't support Atmos, either natively or through passthrough.
It was only the 2017 OLEDs that got Atmos, not even the Super UHDs.
Even with the backwards compatibility of the DD+ codec, the chip inside the UH770 doesn't have the capability to decode the Atmos substream inside the DD+ container
