Hi all, what exactly is eARC or ARC on a TV. I read an article but I don't think it explained it well. Is it used when your audio source is the TV itself (ie: lets say you are watching Netflix) and you want the audio to go to your AVR? Right now I have an optical cable from my TV to my AVR to handle the audio and an HDMI for the video. So is eARC/ARC used so the audio goes to the AVR using the same HDMI cable as the video? Here's my situation. I have to replace my current TV in my basement HT. I mainly play movies from my windows 10 PC or bluray player. They are both connected to my Denon X3400H receiver. would replacing my TV with one that has eARC be beneficial to me?
