Which is why I just ignore the smart stuff and use a capable STB instead.
emodendroket is stating that "ignoring the smart stuff" means disregarding high-quality imaging available on the top-of-line products.
Twirrim is stating that "ignoring the smart stuff" doesn't necessarily mean buying a dumb TV, and that they buy a smart TV, ignore a bunch of the TV's features, and replace them by using a separate set-top box.
Ah, of course. Ok, chalk it up to muphry's law.
Consider a short-throw projector instead: zero "smart" features, multiple inputs, relatively portable, adjustable screen size.
But it doesn't have to be that way, even if it is right now. I wish there were a way to explicitly signal "I bought this Smart TV as a dumb display, and I'm using smart features, just not the ones provided by the TV". If enough people were known to be doing that, it might suggest a market for high-end dumb TVs.
Get yourself a big computer screen instead? That's what I use.
