Someone a while back on a thread not dissimilar from this one suggested looking into commercial display screens. A kind of BYO solution to the smart TV problems.
The nice thing about Samsungs is that basically all their remotes work with all their TVs, so I just found one without the smart button so I can’t tell that mine is smart, and I obviously never connected it to internet. I think it’s a lot cheaper than trying to get a commercial dumb TV too.
Weren’t Samsung TVs the one that would connect to neighbors TVs and stuff and find other ways to connect to the Internet?
I’m curious about the need for non-smart TVs… Are you using it exclusively with a game console or is there some sort of other device you use with it?
