Just don't buy a smart TV. Buy a good "dumb" TV (or just get a good large monitor), then hook it up to a set top box (with TV capabilities as needed).
... and that's the trick, isn't it. Have you ever tried going into an electrical store and buying a dumb TV any time recently?
If you want a good panel, you're going to have to buy a smart TV.
Just don't ever let it connect to the internet.
"Just a good large monitor" costs a fortune.
If anyone could recommend any dumb TV with good panels in EU, you're more than welcome.
