Yea dude I’ve got the 860. Only reason I tried the tv is cuz I have a vizio 65in m-series from 2015. We’ll three of my hdmi ports are 4K @30hz and port 5 is 4K @60hz so I plugged Xbox into port 5 figuring it’d be the best one to have it in. My tv doesn’t have hdr, the vizio got hdr in 2016. When I had it in my tv I couldn’t get atmos cuz of using the arc but I plugged it back in my avr n I’m able to get it. I think I’m supposed to switch my 4K mode in my Yamaha to mode 1 for 4K n hdr cuz it passes it I believe, maybe you would have some insight on that cuz I’m not positive?
