Our TV just went kaput (after 11 years, thank you for your service) and there's no way I'm getting an Internet-connected TV because I'm already worried enough about my blood pressure. There don't seem to be many consumer options, but is there some reason why we shouldn't just get a commercial display intended for digital signage, like this one?

@mogwai_poet At the escape room we have now-normal modern smart TVs and just never give them the WiFi password and that works totally fine. They can still show HDMI!
@aubilenon Yeah that seems sensible
