I got myself a normal, non-smart Philips 49" TV some ten years ago, it's good, but I don't expect to be able to find something similar anymore.
If you want a very specific example, the original nintendo DS can only connect to WEP connections, which meant that when I was there I was able to play parts of DS games that wouldn't have been accessible in the west
I have yet to receive a software update on any of my smart TVs that brought in any positive feature.
I’m starting to wonder if a monitor and a soundbar with an external tuner is possible.
A decent-ish TV-sized panel with at least a single HDMI input really is all I need.
