Message: [QUOTE="strikes2k, post: 4651374, member: 207082"] eARC is a new standard that enhanced another standard called ARC. ARC stands for Audio Return Channel and is designed to send audio from the TV back to a receiver or sound bar so you don't need a dedicated audio cable such as an optical cable to go from the TV to your soundbar/receiver. Both features would be something used via the HDMI ports on your TV so it's not a special port; it's just a feature of the HDMI ports on the TV. Doing a quick search on your TV model number it looks like it came out back around 2016. The original ARC spec has been around since something like 2009 so it's likely your TV supports it, although I didn't see anything specifically saying that in looking at your TV. I think eARC came out a couple years after your TV so I doubt it would support eARC. [/QUOTE]
