What is HDMI eARC, and do I need a special cable for it?
eARC is the newer version of ARC, which sends the TV's sound to a soundbar or amp over HDMI, with enough room for lossless Dolby Atmos. It works with any High Speed HDMI cable that has an Ethernet channel, which is almost all of them.

Worth knowing
- Both the TV and the soundbar need eARC sockets to use it. Otherwise they fall back to ARC.
