Here's a dumb 43 inch screen. It's sold as a gamer monitor. It's a UHD TV display with HDMI in and no onboard smarts.[1]

Here's another Samsung dumb screen, at 55 inches.[2] This is supposed to be for digital signage, but it's really a UHD monitor with HDMI in. But the next size up has "Alexa built in".

Sceptre, which mostly supplies Walmart, has a whole line of dumb TVs, including some big ones.[3] They're a little company in City of Industry, CA, which seems to have found their niche in dumb TVs.

There are lots of "digital signage" displays available. They're usually very bright, reasonably rugged, OK for 24/7 operation, immune to burn-in (they may spend their whole working life displaying mostly the same fast food menu), but not that good
