Just buy a TV and don't connect it to the Internet. I have even seen people remove the WiFi daughterboard. That's essentially your "very large monitor." You absolutely do not have to endure the adware and privacy invasion of content recognition and other spyware. Beat the TV manufacturers at their own game.

Or a TV where you can rip out the internals and replace them with some cheap dumb board. Not sure where you'd find a reputable one, though, as that's the perfect audience for hidden backdoors.

Naturally I would say, but that doesn't have speakers... but you can't even buy a TV without having to buy a soundbar or any sort of sound system anymore. Infuriating.
