AFAIK the problem with those is that they're overpriced and have inferior picture quality. I guess if you want to make a statement or something they're worth buying, but for now I still think your best choice is to buy a "smart tv" and don't connect it to wifi.
I was under the impression that commercial displays optimize for longevity instead of picture quality. Is that not the case?
Correct - they’re usually designed for always-on signage like you’d see at an airport.
