There are business models that are dumb displays that you bring your own device to do conference stuff on whatever platform you wish. I'm not current with the pricing but they typically have good warranties.
They are insanely priced compared to disposable Vizios - renting a "real" display monitor for a conference would be $1000 or so (including the shipping, setup, return, usually involving large crates and trucks).
Buying a similar Vizio would be delivered by free by Walmart for $200, you just ignore the setup prompts, stick HDMI in, and give it to a nice hotel employee when done.
This was a what can we order under X dollar amount from Target kinda thing. We bought 2 TVs a month for several years.
