Just wanted to add that you'll pay out the ass for them compared to consumer trash, but there's a reason for the higher price tag. They're often made for heavy usage environments where they're on like 24/7 for years showing slideshows and shit in office lobbies. Consequently, they often lag behind the feature set of modern TVs which may or may not be a problem (personally I hate all that image enhancement shit but everyone has their preference) and the higher refresh rate is not as big a selling point so not a huge comparison there if you're looking to use it for gaming or something. They also have a much more clear repair path though replacement parts can be fuckin stupid expensive. It's bullshit that the only way you can get around the enshittification of consumer electronics is by paying the enterprise tax but that's how it is.

I work in IT and about once a year or so I have to spec out that sort of stuff for clients, and they're always like "WTF?!" when they see the cost of some of that Enterprise/Professional grade stuff, but the difference is, the no-name crap they could get for $1499.99 from a big box is going to burn itself up within 18 months and be trash while the $5000 display will be humming along for as long as replacement parts are still available.

Or just don’t connect it to your network? Or DO connect it to your WLAN and block it from communicating to anything else.
