A:Answer For Dolby Atmos to work, every ingredient in your home theater setup has to support Atmos. In other words: The movie that you're playing, whether it’s physical, downloaded, or streamed, has to be encoded with Dolby Atmos (via Dolby TrueHD or Dolby Digital Plus). The hardware you’re playing it on has to be able to decode Dolby Atmos or pass it along to a Dolby Atmos-capable sound system without altering it. This is known as “pass-through.” The app you’re using e.g., Plex, Netflix, iTunes, Amazon Prime Video, etc., must be capable of delivering Dolby Atmos data to your playback device., and of course, your TV, A/V receiver or soundbar must be Dolby Atmos compatible, if that’s the device you’re using to hear audio. So even though the LG CX 55 inch Class 4K Smart OLED TV w/ AI ThinQ® (54.6'' Diag), Model # OLED55CXPUA and the 2018 C8 can easily handle the TrueHD/Atmos track, the obstacle to getting Dolby Atmos will be your non LG Dolby Atmos Soundbar because it cannot decode the Dolby Atmos signal...^IFV
