The good news is streaming service apps like Netflix, Amazon Prime Video, and Disney Plus encode Dolby Atmos into the lossy Dolby Digital Plus format, which means ARC can handle Dolby Atmos audio from these sources.^Ivan If you want to go beyond the limitations of ARC, you’ll need hardware that supports HDMI eARC. If your TV is HDMI ARC enabled, but your AV amp or soundbar is compatible with HDMI eARC, you'll likely get a sound – but the bandwidth restrictions of ARC will mean you won't be able to experience the high bitrate audio that eARC can provide. HDMI ARC does not support the Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, or DTS:X soundtracks found on Blu-ray or 4K Blu-ray discs: it will likely only send a 5.1 data stream. Due to the limitations of regular ARC, only eARC can currently process these formats. As a result, with an eARC channel, you can enjoy the depth of movie-theatre-quality surround sound via formats such as DTS:X and DOLBY ATMOS. Higher bandwidth also means that digital audio signal doesn’t have to be compressed and is much more detailed, rich, and vibrant. Higher bandwidth translates into a higher amount of data that can be transferred (a larger pipe). The enhanced version of the Audio Return Channel has a much higher bandwidth than its predecessor. The main differences between ARC and eARC lie in bandwidth and speed. Our Bluetooth-enabled Soundbars can be paired with our Bluetooth-enabled TVsor you can connect our Soundbars that have HDMI ARC or HDMI eARC ports to our TVs that feature HDMI ARC ports or HDMI eARC ports. The most common way for connecting a Soundbar to a TV is connecting the TV's Optical Digital Audio Output to a Soundbar'sOPtical Digital Audio Input. It's more a question of connectivity more than it is a question about compatibility since all our Soundbars are compatible with any of our TVs, including older LG 3D LED TV models.
