I’ve been looking for a TV for awhile now, and I’ve found that there aren’t really any practical dumb ones. There are a few models, but they’re more expensive and have lower specs, cheaper panels, fewer menu options, etc.
Overall, the smart TVs are going to be cheaper/better because the company plans to make money on target ads, data mining, etc. Just don’t connect it or enter a wi-fi password. Sadly that’s where we’re at now.
