Sadly the Samsung TV I have was the best display for the price by a mile, so I've done what i can to balance usage and protection. Its connected to the wifi to allow for AirPlay natively. The tv has a fixed IP at the router to block all traffic in and out of the network, and as a visibility layer its DNS'd through a PiHole too.

Its unbelievably talkative over the network! In the 7 days just passed, its been 90% of the blocked requests by volume (there's no allowed domains from that IP).

I'm still not convinced it isn't sneaking out data somehow - piggybacking off a connection somewhere to the neighbors TV. Its HDMI runs through a stereo amplifier, so it can't piggy-back off the connected PC that runs it.

Maybe the PC (Mint) can run AirPlay somehow and I can disconnect it entirely from the internet?

I feel overly paranoid about this device relative to everything else in the house, I'm not sure how justified that is.

I think we've overshot the mark a bit about TVs' connection abilities. A built-in SIM was one early conjecture. And while it hasn't been seen in the wild, it is often assumed to exist.

More to your point, we've not seen connections (assumedly ad-hoc wifi) to a neighboring device and uploading data to manufacturer, partner, etc.

We have recently seen a case of data collection, that included wifi scans. What we have not seen is a device that connects to other APs on it's own.

I saw 1 redditor claim that this occurred but it was not substantiated. Lots of folks are looking for this behavior but it hasn't been found.

This tells me that our existing methods of self-protection are effective.
