Any TV that you want. Just don't connect it to a network. Why is this hard?

Sceptre dumb TV. Failing that, large computer monitor or digital signage display. You WILL pay a premium.

Rather than trying to get a TV which doesn't have blatant spyware (when in all likelyhood, they all do, or will get one in a software update), I would suggest solving the problem the other way around - get a TV you know you can disable that functionality in. Trusting the manufacturer is a recipe for disaster.

I stripped out the bluetooth+wifi module from my TV and keep it disconnected from ethernet. Now it doesn't matter what it tries to collect, it can't send it anywhere.

SOFTWARE SWITCHES CAN NEVER BE TRUSTED!

Next TV I buy im connecting to to Claude code and lobotomizing it...

It's like every 3 months someone asks some variant of this question.

I'm unsure on current models, but historically the best bet (and what I did last in 2023) was to purchase a TV from Costco, as Costco used to (and probably still does) mandate that SKUs they sell must be able to be operated in a non-connected state. I bought a 70" Sony 4K TV in 2023 and /only/ the Costco version provided this option, but on first power on you could select "Basic Display" or "Connected Experience", and after that unless you explicitly changed it that was set. It's never asked to connect to a network or done anything I can detect as nefarious since, and is used only via an HDMI connected appliance I use for streaming.

Buy a TV from 2016. Mine's a Samsung from 2016. It showed me a EULA on first boot. I declined it. It's been a dumb TV ever since. One input is a LibeELEC NUC, the other an Apple TV, because Netflix requires a botnet to stream >480p.

4K is unironically a meme. You don't need it. A set of decent floor standing speakers (and room treatment) will elevate your movie experience far more than more pixels ever will.

Does anyone know about the kiosk tvs used for professional displays? Do they still make/sell those?

OP, I have been a user of the AppleTV family of products for years. I have no complaints. So far I trust Apple more than Roku or Amazon, and I find the devices work far more smoothly and easily than other players in this space.

Consequently, I have no interest in hooking ANY TV directly to the network. It seems pointless.

I'm 100% not interested in any discussions that begin with "buy model XXX and then install different software..."

I'm not going to hack my TV. I have no interest in sysadmining my television. Success for me would be finding a TV that would work fine for its working life without ever being attached to a wifi network, and that will not try to do so on its own (ie, by joining known-open networks like those provided by Comcast and ATT).
