It isn’t even the smart tv prospect that concerns me with new tvs. My current TV is technically a smart TV but you can’t tell. It has never been connected to the internet.

My concern is the framerate. Some of these TVs, even in the 1080p era, will turn a cinematic masterpiece into feeling like a cheap soap opera. I’m not even sure what to look for to avoid this issue. Limiting myself to maybe 48hz tvs?

You just need to turn it off in the settings.
