3 Tech Questions for Videoholics

SITUATION:
Upgrading a wall mounted, flat panel in a no-window HT (15 ft. x 18 ft.) from an older 65" 1080P Samsung plasma to a 85" 4K HDR display.
- Max budget is $2,300 (inc. ship/tax). HT use is for movies (Blu-Ray and 4K Streaming), TV sports, and also multi-channel audio.
- The two Main Viewing Positions (MVP ;)) are 13 ft. from screen with "cheap seats" in same (only) row 4.5 ft. to each side of center.
Pythagoras says the "cheap seats" have a 20 degree viewing angle.

OPTIONS:
Considering two 85" panels at our local Military Exchange (no ship, no tax); Sony X800H ($1,900) or Samsung Q60T ($2,100).

During my "homework" on these models, on 4K HDR TV Comparison and RTINGS.com, I found a couple video-geek questions I need help with.
I'm more of an audio-centric HT guy, thanks in advance.

QUESTIONS:
1) Does Sony change from IPS panel technology to VA panel technology (like Samsung) on their 75" and 85" X800H models?

- The 4K HDR TV Compare site's comparison table says Sony X800H 75" & 85" TVs have VA panels versus IPS panels on the smaller X800H models.
I was unable to verify this on Sony's site or anywhere else.
- If true, a VA panel would negate Sony's IPS panel wide-angle viewing advantage and contrast/black level disadvantage, making these two models very close in spec.

2) Will a Samsung Q60T (VA panel) adequately cover a +/- 20 degree viewing angle?
- On the RTINGS.com site, the Samsung Q60T (VA panel) and the Sony X800H (IPS) have the following Viewing Angle sub-component values:


TV (panel)
Color Washout Angle
Color Shift Angle
Brightness Loss Angle
Black Level Loss Angle
Gamma Shift Angle
Samsung Q60T (VA)
23 deg​
28 deg​
32 deg​
15 deg
17 deg
Sony X800H (IPS)
42 deg​
60 deg​
44 deg​
70 deg​
59 deg​
- My understanding is the values represent angular deflection from center, NOT a total +/- angle value, so the room's maximum 20 degree viewing angle would cause a VA panel (Samsung, Sony?) to go "red" for Black Level Loss and Gamma Shift.

3) Are there other 85" 4K HDR panels I should consider <$2,300.
- We have a smaller 4K Sony smart TV in another room, so are comfortable with either brand's user interface/quality/etc.

I can't answer your questions, but I would say that when I bought my Sony XBR900 in 2018, it was very well regarded across the board. I was buying it for gaming as well as HT, so I wanted to make certain it was as solid as could be.
No regrets.
I see them listing at 2500 right now... and would say spending that extra little bit is worthwhile. :)

ryanosaur,
Thanks, your response encouraged me to open up the aperture and look at 75" screens with better viewing angle, sports support (refresh rate), and dark room movie performance (local dimming).
- From same vendor found: 75" Samsung Q80T ($2,400) or 75" Sony X950H ($2,700).
The Q80T has slightly better bench marks, particularly in viewing angle, at $300 less cost (on edge of budget) and is the lead dog now.

I was shooting for a "last TV" size for the room, but desired performance within budget will drive one size smaller.
- Still a large upgrade: adding 4K, HDR, and 33% more screen area (1800 sq. inch vs 2400 sq. inch)

Good point. My kids could stand to learn that...
My kids used to look at me like I was Crazy when I told them some of the things I grew up with. Now my Grandkids 3 - 13 look at me like I'm crazy. It's funny when I look at their faces looking at me when they are thinking (Grandpa's Crazy)
