Newly purchased Vizio TVs now require Walmart accounts to use smart features

Walmart wants to connect what people stream "directly with retail interaction."

Ars Technica

Is there any kind of “hook up” on wholesale large dumb displays?

I know I’m preaching to the choir, but I just want a giant dumb display from my Apple TV. I vaguely remember someone posting a link to tvs restaurants use but I don’t remember exactly what or if it was what I’m looking for.

(Sorry, being lazy here)

Look for used 'Digital Signage' or 'Commercial' displays. They usually have dumb firmware and the same panels as retail models.
Most are also larger, heavier, with higher power consumption, and sometimes uncomfortably high minimum brightness. They rarely use the same panels as retail models because they have to support different operating conditions like extreme temperatures and 24/7 operation.
