Unfortunately it’s getting hard to find dumb TVs. The only real options are pro-AV or digital signage displays but even a lot of those are now moving to being smart. Our 15 year old bedroom TV finally died last month and we ended up having to replace it, and we ultimately went with an LG. I’ve disabled it’s wifi though. It’s a frustrating situation. I wish one of the manufacturers with good displays would just offer a dumb line of TVs. I imagine they would still have a market even if they were higher cost to make up for the lack of ad revenue, but maybe I’m underestimating that revenue. Either way, avoiding smart TVs is getting extremely difficult these days.
