> Never buy a consumer product that expects an Internet connection. This is a nice trite trope, but getting an affordable TV without these features might be nearly impossible for most people these days.
Just looked at a price checking site, checking the oled and "no smart tv" boxes. Zero hits. It is not a question about affordable TV. The only ones that does not have smart features (as far as I can identify) are the cheapest LCD ones at the bottom of the price list. The best alternatives that I can find is projectors or monitors, as those seems to so far not expect an Internet connection.
But you can forget about common TV features like HDR support, DTS/DD audio decoding, usable remotes and other useful features.
