This is a 100% trash point. I have yet to see an unknown device on my network from a dumb screen, let alone any additional microphones or cameras on said dumb screen. I have also not seen or heard of any reports of it becoming a spying type device. You mean to tell me the dumb panel I bought, which is from a major manufacture with known tear downs and a ton of buyers, managed to sneak this hardware in (even something like a cellular radio) and nobody noticed?
I'll repeat this for you so you perhaps it will impact you this time: Show me a dumb TV that has been wired up to spy on people that has been in the wild before.
