Technically you can get commercial TVs but many companies stopped selling them. They are literally the new screen tech with no "Smart" capabilities. They are also much cheaper than their smart counterparts.
Some people have mentioned apple TV, for now that at least isn't riddled with ads. Others have mentioned getting android sticks, but I'm not sure how smooth that process is (or how well they work with remotes).
A Sharp Aquos TV from the late 2000s, pre-Hisense days. I have a 42" model from 2007. 1080p, plenty of I/O for modern and legacy equipment, and lots of configuration options. It's an absolute monster at 75 lbs, but is an incredibly high quality unit, especially for it's age. I've owned it since 2019 and it's needed zero repairs.
For reference, we also have a much newer 55" curved Samsung TV (in our basement, wall-mounted up high) which that has already needed its display driver board replaced.
