Am looking. My unit is a Panasonic 50’ plasma I got in the noughties. Right up my alley - no smart features at all. I’m aware there are business displays that they use for digital signage, but like the TVs, they have terrible sound, so you may need to fork for a sound bar or something. They cost a bit more, but afaik no smart features either, just media select.

Dude, you can’t just say “perchance”!
