It's easier if you stop looking for a TV and instead get a display. I like NEC. They are designed to run in retail but they work great in place of a TV.

Interesting. How do you stream stuff to them? Do they have an OS?
I saw at least on display running Android. But I didn’t check all of them.
Running Android puts you back with the same problems. Software updates and data collection out of your control. I prefer a display with the only software being for basic display settings (color, brightness, etc). It's really just a massive computer monitor for retail displays. But it looks and functions just like a "dumb" TV.
I use a mini PC running Fedor. Specifically, this one
No, they don't have an OS in the sense that smart TVs do. They just have the basic software any display has for controlling brightness, color, etc. It's just a good old fashioned dumb TV when you use it like I do. It's incredible how that's a lost concept now. A sign of aging I suspose. Unfortunately, remembering freedom and respect seems to be one of the signs of aging now. Even our TVs abuse us.
