At long last, the set is up and running.
Yes, installing the legs was easier than I'd thought. (Thanks, Audioguy1--it's just like you said!) Best Buy has a video of it here: https://www.bestbuy.com/site/clp/bby...wid=1732265868
After some unexpectedly necessary tinkering, I am very happy!
And by that, I mean this 4K stuff is sure as hell not plug and play. I wish I didn't have to feel silly for not knowing that only HDMI ports 2 and 3 on Sony TVs carry 4K HDR signals, or that I had to go deep into the menus to turn on their "Enhanced" features and even see the benefits of the TV.
Then there was the matter of my receiver, a Sony STR-DN850 from 2015. Apparently, it does not pass HDR. I solved this by connecting my Xbox One directly to the TV and the TV to the receiver via the HDMI ARC port. After some additional fiddling in the receiver settings, it all plays nicely together.
I sort of had to forget all that I knew about calibrating an SD TV (I am coming from a 2014 Samsung H7150 in 75" size), as I was tempted to turn down the contrast straight away. Turns out (duh), that's a no-no for HDR, and the difference between a contrast of 99 or 100 and, say, 95 is very significant.
Playing Call of Duty: Modern Warfare, I clearly noticed increased details in textures and effects such as swirling dust motes. Colors are rich and vibrant, and lighting and reflections have much more impact than I ever saw before.
Motion handling seems great, too. Smooth and clear, just as it looked in the store.
I only watched a bit of TV through a Roku plugged into the back of the Xbox, but I was surprised how good it looked. We are using PS Vue (I'm so pissed that Sony is shutting it down), and while it only broadcasts in 720p, it looked better on this set than the 1080p Samsung we are coming from.
Netflix looked terrific. Even before I had fixed everything to display at 4K HDR, and while I was still viewing standard HD material, the picture was gorgeous. Again, a large improvement from our older screen, and that's to say nothing of the additional impact of the humongous 85" screen.
Lots more to do--streaming 4K Netflix, watching more TV and BD movies and 4K BD movies. But so far, so great!
Tomorrow is an all-day game-athon with my friends, so that should be interesting.
