I was looking for dumb tvs a little bit ago and it's quite hard to find. Every company wants to turn their hardware sale into an eternal revenue stream.
They are not hard to find at all. Sure it's more 'difficult' than searching for 'TV' on Amazon, but if you spend ten minutes doing a web search, you will find some brands.
Alibaba. I'm just buying what are basically big monitors. I'm paying what feels like a premium price for a screen, one power and three HDMI input - only. Lack of other BS is the premium feature.
Edit: down thread someone calls it "commercial display" - search for those.
