Let me just start out by saying MAN I LOVE THIS TV!!!! I picked it up last September. I had a Samsung plasma that crapped out on me. The Sony is 4k of course. I have the Sony X800 4k player to go with it. Like many of you, I'm such a tweaker I played and played with settings. I'd read about some settings, I'd give it a try. On the Sony XBR page on FB, someone sent me their calibrated settings. They were some really good tweaks. I'm a color matcher by trade (25 yrs) so I think I have a decent eye. One thing that surprised me was how incredible regular blu-rays looks. I was like DAMN!! 4K movies? Yep, they are incredible too. But IMO, some I've seen are no better than blu-ray. The one downside to such a great set is the same with a great audio system. It can be too revealing!! A bad picture can look really bad. LOL Right now I'm watching 'The Last of the Mohicans' I recorded on DTV. I was on BBC America. It's watchable because I love this movie. Netflix 4K is great. Not incredible in my opinion, but a great picture especially since it's a streaming service. Same goes for Hulu and Amazon. I don't watch close enough or care enough to compare each streaming service. Now toss in BR 4K versions of BR2049 or Passengers just to name a couple and I think the picture has to be better than any movie theater I've been in. Then I pulled up a YouTube video of Downtown LA aerial shot at night in 8K. Of course my TV is only showing 4K, but this video left me in awe of the best video I've ever seen on a TV in my life. Flying over head and seeing the detail of the city is nothing short of amazing. When I watched my first BR on this TV I thought it couldn't get a whole lot better. Then I watched BR2049 and noticed an even better picture, but then the YT video of LA left me speechless. I would love to see it on an 8K set. But what I realized was this video was showing off the capabilities of this set. So I'll leave you with this.... MAN I LOVE THIS TV!!!
