The only 4K video I watch is either streaming from TV apps, or 4K player which is HDMI direct to tv, with audio via ARC. And since I only have 5.1, is there any advantage to Atmos or DTS:X? And I use a Harmony remote, so video and audio switching is programmed through that.It really comes down to whether or not you want the receiver to switch 4K video, rather than switch audio and video separately. A new receiver will handle and switch everything, plus it'll have immersive formats like Atmos and DTS:X.
Yep, but this is where it gets confusing. I have to admit I might not have it all hammered out, but... eARC can pass HD audio, but I'm not aware of any streaming that has HD audio. Some streaming services, most notably NetFlix have some with Atmos, but it's Dolby Digital quality, not HD like on a disc. And you only have 5.1 anyway, so it's arguable that there's nothing for you to gain from streaming Atmos.Got it. Just looked at the 4K player manual. I've had it hooked up wrong. But with a first version ARC, doesn't that mean that the UHD streaming from the TV apps would max at Dolby Digital only, because the audio originates from the TV, goes to the AVR through the HDMI ARC?
