>I wish it was only a 30-50% premium though as my experience is that they are an integer multiple of the equivalent consumer TV You weren't kidding, just had a quick browse for some, they were between $5000-$17000 for sizes equivalent to home TVs. |

I'm very happy with my current dumb 65" 1080p screen, but have thought about whether I would pay signage screen prices if the only other option was something with its own rogue computer - smart TVs really are terrible in every iteration I've seen. Eventually I may desire more resolution or size, or my screen may have an irreparable failure.
Having modded thinkpads to use better / higher resolution panels, and having disassembled a number of consumer TVs, I do suspect that the next best option is going to be getting a dumb driver board to accept HDMI and turn it into the LVDS / EDP / whatever interface is needed to directly drive the panel (as well as a backlight driver, and something to spit audio from the HDMI to some speakers). As it gets harder to buy a quality large screen without crapware (without paying signage prices) I hope enough of us will pursue this route that there can be a known process and BOM to make it a straightforward project. I would imagine you could have your cake and eat it too by pairing up a quality dumb driver board and a high quality screen that is not available in dumb form.
At that point we could consider interesting modifications like a teensy with ethernet to allow remote control over LAN with a protocol like OSC, or some lightweight hardware to decode an NDI stream to allow creating "channels" coordinated by a centralized media server / NAS. One could accomplish interesting things that would be concerning if not under local-only control, like video calling that hops between screens in the house as you change rooms, shows that automatically pause if you get up for a restroom break, gesture control for when you're watching a cooking video while cooking and have dirty/wet hands, and so on. There is a ton of smart home functionality around screens that is compelling and useful when not paired with creepy companies or unknown data exfiltration.
