Anyone who owns an LG smart TV must inform all guests and family members that they are being monitored – this is required by LG’s current terms of use. Meanwhile, LG monitors install potential malware and surveillance software on a connected Windows computer.
Not impossible, several options are still out there if you actually search for “non smart TV” on retailers’ websites.
Sceptre was one brand that made decent non-smart TVs but they seem to be vanishing off the market now. Many used ones still on ebay and other secondhand markets. Their website still shows a bunch of TV models but the retail links turn up empty.
I searched and didn’t find anything in Europe. And that was couple of years ago already. Maybe there are some sources I don’t know about but I didn’t find any in typical stores.
