Thanks Dan.
First, let me reiterate how much I appreciate people trying to help me with this!
I checked all of the ports on the tv, and the only adjustment that can be made is "Full UHD Color" which I have, of course, set to "on." There's no other options for adjustments on it--"Picture size" and "Picture position" are greyed out. The TV manual clearly states that it has/accepts Dolby Vision and has the 60 refresh rate. Maybe it just can't have both at the same time?
Cheers,
Mike
I just tried some different search terms and found this reddit thread for this exact question. It looks like the answer is that it just won't work, but it's still a bit confusing to me. Seems like if the ports are 2.0 that's not quite good enough. If anyone wants to interpret it for me, I'd be thrilled. 🙂

OK, just tested my Stick 4K+ on my Vizio V405 TV. The Stick reports the display as 4K/Dolby Vision capable. I used the Disney+ app for testing, as that's the only streaming source I have with DV content. I selected the original Iron Man movie to test, which D+ says provides DV. Once the movie loaded and began streaming, the Dolby Vision icon appeared on the screen. Pressing the info button on the TV remote confirmed it was a DV video being displayed.
The Stick 4K+ (3821) has HDMI 2.0b, same as my Ultra 4800. So there's no question that Dolby Vision does NOT require HDMI 2.1. I will say that neither my Vizio nor my LG TV (the only two DV capable displays I have) indicate the refresh rate, so I can't say for certain if they are outputting 4K/30 or 4K/60. But that's immaterial since I am absolutely getting DV on both TVs.
Thanks Dan! That's good to know. I'll keep digging around...or give up as I'm not sure how much content has DV anyway.
Much appreciated!

From some quick searching, it appears Dolby Vision will pass 4K/60 on an 18 Gbps connection, which is HDMI 2.0. The only Roku player that has HDMI 2.1 is the new Ultra 4850. But my Ultra 4800 does DV streaming Disney+ (the only DV source I have other than some test clips) on my LG Nano85, and I'm pretty sure that all three devices (Roku, Yamaha AVR and TV) are only HDMI 2.0. I'll test my Stick like I mentioned later today and let you know how it does on my only Vizio TV.
