HDMI ARC and eARC: What they are, how they work, and why you should care

By Ryan Waniata — Posted on December 1, 2017 9:13 am

If you’re the owner of a 4K TV or newer HDTV, A/V receiver, soundbar, or home theater in a box, you may have noticed (and then promptly forgotten) a little symbol on one of the device’s HDMI inputs that says “ARC” or “HDMI ARC.” What does this mean? Hint: It has nothing to do with the reactor that powers Ironman’s suits.

ARC stands for Audio Return Channel, which is a little-understood protocol that started showing up on HDMI-equipped devices a few years back, standing today as a ubiquitous standard. The technology is especially useful and has the potential to significantly simplify your home entertainment system. Unfortunately, few know it even exists, much less what it can do.
