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 you can just get a smart TV (they are dirt cheap because they are subsidized by ads) and then install android/linux on it
@mogwai_poet AFAICT the difference between a "display" and a "TV" is that a TV has a number of input options and a way to change between them, as well as built-in audio and ways to control said audio.
@cosine @mogwai_poet True, the Samsung I got was labelled as a “business-class TV". Has sound. (My partner thinks I need to add a sound bar, though.)
@zarfeblong @cosine Yeah the internet consensus seems to be to just make sure it's one of the ones that still works if you don't give it the wifi password and you'll be fine
