Are there quality but affordable large HD/UHD/4K "stupid" screens?

LOGINS SUC writes: Truly in the first-world problems category, I've been looking for large format (>55") HD/UHD screens for home entertainment. In light of the recent Samsung big-brother monitoring and advertisement injection concerns, does any reputable manufacturer still make "stupid" TVs? I don't want to pay for all the WiFi, apps, cameras, or microphones. I don't need it to have speakers. And at this point, I don't even care if it has the TV receiver functionality. All this stuff leads to vendor lock-in or is well on the path to obsolescence by the time I purchase the device. I prefer all of this non-visual functionality be handled by devices better suited to the purpose and I don't want to pay for screens including these widgets I have no intention of ever using, at all.

I've searched all the normal retail outlets. If I find anything, they are wildly expensive. "Computer monitors" fit the bill but are almost all 55") LCDs in the sub-$3,000 range anymore? Are projectors the last bastion of visual purity for home entertainment?
