Things like this are why I never will buy a so-called smart tv, the only exception being is that it is better/cheaper than alternative and in that case will keep connectivity disabled like you did.
Good luck in 5 years, there will likely only be an option or two left and they will be as shitty as today's flip-phones. A few years ago I was in the market for a TV and was flabbergasted as to why I couldn't get a nice, big, 'dumb' TV.
Yeah I intentionally bought a dumb TV instead of a smart TV five years ago... recently started thinking about whether it might be interesting to upgrade to a 4k and/or OLED model before discovering that they’re ALL smart.
I've looked in the past and could never seem to find one. Do you happen to have a link on hand? I'd be very interested, especially if it also supports HDR.
