I love how literally nobody is answering your actual question.
I agree that this is problematic and we need TV reviews to include at least some of the information you cite.
If it helps, I have an LG smart TV. It complains if you don’t let it access the internet at setup, but if you connect it once and let it do its initial patching, you can decline all agreements and not get nagged until it tries to update again. To keep it from further updates, you can disconnect it from wifi and it doesn’t seem to try to reconnect. I can’t speak to public wifi because there aren’t any open access points near my TV.
In contrast, I have a samsung TV that loses its mind if it can’t connect to the internet and becomes basically useless for all the nagging.
I think the current received wisdom on Linux gaming boils down mainly to three letters: AMD. As a company they’re “friendlier” to Linux for drivers and such.
That said, I’m running an 11th gen intel i7 and nvidia 3080 and not having any problems. I haven’t tried starfield yet but Baldur’s Gate 3 runs like a champ.
The Samsung tries to “identify” what’s on an hdmi input before it will connect. It seems to call out to the internet to do that because it takes forever to fail and show you the display anyway when it’s not connected to the internet. Even when it is connected, it takes a stupidly long time to switch to a new input. I super hate it and will never buy another samsung tv.
I guess the lg needs to boot tizen before it works, because I see the logo briefly but then it goes directly to the last used input with no other bullshit, so it’s fine with me.
