Many smart TVs still give you popups telling you to connect to the internet or they simply refuse work without connection. There’s not a very good way to tell if any smart TV you get will do this ahead of time without looking over reviews, and even then many people just connect their TVs anyway so it might not show up there either.
I’d prefer to just have a display that works as a display from the start and not have to worry about it.
