I have read forever the charts that say "if you are X feet from the screen, you will need a TV at 100" to see a difference." I'm 50 years old.. my vision is 20/20 (just had my vision checked) still but I do use reading glasses from time to time. And I can to throw the charts away.
Now comes the fun part.... In the living room I have a 2013 Panasonic P65VT60 65" plasma (last year they made plasmas I think). Im wondering should I replace with a TCL 65 or wait til a TCL 75" comes out later this year or next year? I'm 13.5 feet back from that TV
This is probably the best resource for distance from a TV: https://www.rtings.com/tv/reviews/by...e-relationship
So, according to you the specs you gave us, you're getting about a 20 degree view of the screen at 11 feet away from a 55". At that distance, you're on the line between whether 720p content is distinguishable from 1080p. Let's be generous and say that your eyesight and discernment is very good, so 1080p is definitely worth it. You're still not really getting much actual 4k detail. Now, the colors and HDR of the screen will still be a "wow" moment, but at that distance you can't possibly be seeing much difference between 4k SDR and a normal bluray.
For your second TV, you have about the same arc of viewing at 20 degrees. That's compared to the recommended view of 30 degrees for mixed usage. Again, you're in the gray zone between whether you could even tell the difference between a 720p video and 1080p video, encoding quality being equal. So I'm happy that you're happy, but yeah, you're not really sitting close enough to the TV to get any benefit from 4k. You are probably seeing a lot of new color and dynamic range detail, and not much of the sharpness beyond "yeah, it's sharp!"

At what distance is UHD vs HD noticeable on 65in tv?
8 ft for full HD
4 ft for full UHD
With the same source, you are sitting way too close to your TV, even for Cinema use. 6 feet is the sweet spot. You're still in the Ultra HD range for detail, so you won't be seeing individual pixels, but that viewing range is probably uncomfortable. I'm just imagining you swinging your head back and forth constantly just to see what's going on on the screen...

I really wish this TV panel had a native 120hz and would be instant buy for me. I think I might just hold back and wait for the new vizio p series 2018 line up to come out.
It doesn't matter what the TV supports, no one is going to get more than 60 Hz at 4k. That's a hard limit on HDMI 2.0 bandwidth. Going beyond that bandwidth could lead to the PC or TV port getting fried. Perhaps the TCL can be overdriven at 1080p or 1440p, but I doubt it. TV's have a lot more signal processing and abstraction than PC monitors. It will probably just not display at higher refreshes, or skip frames. Who knows, I'm curious too!
