If you insist on a dumb TV and are in Silicon Valley I'll sell you my Panasonic 1080p TV from ~7 years ago. It's got an IPS panel!

Some of these are non smart but large.

Yes, that's a computer screen. But it's 43". That's what you want. (I have it in my living room and you couldn't tell the difference).
