I’m lucky enough to have the room for a TV and chair so I take advantage of it. Though I do mostly spend my time at the computer, so I have a small TV next tot he computer and just stream ad supported shows that I only half pay attention to. We all do what works for us.
I went with Sceptre, as for the specs, I’m half blind so all I can say is I can see everything clearly.
I mean that works too, I’m just not a fan of watching things on computer monitors. Sometimes I just want to sit in a recliner and watch a movie on a larger screen.
You can still buy dumb TVs you just have to search for them. You can also go off brand and get a dumb TV from a brand like sceptre.
Non-smart TVs are still available, they just cost a bit more. As for the connectivity issue, China has been caught hiding 5g chips in electrical control systems and city buses, and selling “free streaming” boxes with malware that scans networks and attacks targets deemed worth while. And all these TVs are being manufactured in China so why take the risk when you aren’t going to use the connectivity anyway?
This is why I don’t buy smart TVs in the first place.
I just went to the Sceptre website, they have non-smart TVs listed. You just have to look at the listings. I’m sure there are other brands, I’ve just had good luck with Sceptre so I stopped looking.
