The main benefit of eARC is a big boost in bandwidth and speed. ItвЂ™s a feature implemented in the most recent HDMI 2.1 specification. What is HDMI eARC? What are the benefits?Д®nhanced Audio Return Channel (also known as eARC) is the next generation of ARC. These services embed Dolby Atmos in a Dolby Digital Plus stream, which ARC can handle. If you want this level of functionality, youвЂ™ll need HDMI eARC.ДЄRC can, however, allow you to receive Dolby Atmos audio from streaming services that use the format, including Netflix and Amazon Prime Video. It simply strips out the core 5.1 data stream. ItвЂ™s worth noting ARC doesnвЂ™t allow you to bitstream the full-fat high-quality codecs such as Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio or DTS:X soundtracks that you find on Blu-rays and 4K Blu-rays. Some TV manufacturers only support Dolby Digital, while others only support two-channel stereo, defeating the point.

Labelling isnвЂ™t compulsory, but as long as your TV is a late-2009 model or newer, there should be one at your disposal.
