What is eARC and how to set on Samsung Smart TV?
eARC enables the sending of audio to a TV that originates from cable, satellite, streaming or source devices to be sent to an AVR or sound bar through a single HDMI cable. This ensures the simplicity of the connectivity and that the original audio can be experienced.
HDMI ARC and eARC differences
Most TVs compress audio signals in advance before going through HDMI cables. The eARC (Enhanced Audio Return Channel) enables you to transmit the original full resolution audio signal through an HDMI cable and reproduce the best sound without compromise.
The eARC is a feature implemented in the latest HDMI 2.1 specification, the biggest advantage is that it exceedingly improves bandwidth and speed. This allows you to transmit high quality audio from your TV to your Soundbar or AV receiver and is compatible with the high bitrate formats Dolby Atmos.
eARC is also popularly referred to as the next-gen ARC. It proves support for larger bandwidth and supports faster speeds. Therefore, you are able to deliver higher quality audio from your TV to your soundbar or audio receiver.
