I foresaw myself coming up against this problem 5 years ago and got myself the largest dumb TV I could find at the time. Still going strong.
@UncleIroh I've got a 65" LG I've had for almost a decade. Almost got rid of it last move, but now I'm glad I kept it.
Nice. Keep that bad boy and don't succumb to the tyranny of back-doored "Smart-TVs" with their pre-programmed ROMs.
No in-built bluetooth, microphones, wifi, or ethernet.
You can get all the benefits of a smart TV by plugging in a raspberry pi or equivalent, loaded with FOSS media software via HDMI.
There are tons of articles about it. Here's just one: https://safereddit.com/r/privacy/comments/1fsri2c/my_wakeup_call_how_i_discovered_my_smart_tv_was/
