My "Smart" TV is a new 4K Samsung screen that I never connected to the WiFi connected to a Media PC running Xubuntu. I don't trust the security on any networked device I don't have the source code for (and I don't really trust the media PC hardware either since its intel, not a fan of their security policies).
