yeah, anything media is hard to get without "smart" stuff, but you don't need the bluetooth enabled shaver, trust me.

i also bought a tv/monitor recently and the size and features i wanted were only available on a smart one, but i never connected it to the web. it just complains about it in a grey box top right every start. it probably uses a bit more electricity, because of a proper CPU running all the time.

Probably not in stores, but you can get PC monitors up to about 43", and there are also "commercial signage" or "business" displays which are about $150-200 more than a similarly spec'ed smart TV from the same company (lots of Samsungs on Amazon), and may not come with a stand or possibly speakers. Some smart TVs also let you switch inputs without connecting to WiFi. I think most mainstream media projectors are not smart yet, though it's creeping into that space as well. If everything else is already tracking you, I do tend to wonder how much worse the TV is, but there are ways to pay for a little less privacy invasion from your "TV."

I’ve been searching for a dumb TV now for a bit, can’t find them anymore

Every TV can be a dumb TV if you don't give it your wifi password...
