@fatsam We're still running on a 2012 Panasonic 1080p TV. It works fine, and I declined to pay extra for a wifi/ethernet board so it's entirely incapable of snooping on us.
I'd buy a 4K display as an upgrade if I could figure out how to get one entirely free of baked-in spyware. (I'd only be using it as an HDMI display for the AppleTV, anyway.)
