    I saw one where they read HDMI over the air from 60 ft away.

    Wow! Was that stuff even EMCD compliant?

      You can read the cables, you can read the transceivers in the video card, in a lot of the screens you can even read the panel changing itself.

      Our ability is to remote sense EMF is absolutely ridiculous these days.

      Then there’s crap like the espionage where they change fan speeds. Or flash an infrared proximity sensor on a cell phone to exfiltrate data.

        I thought that stuff went away with CRTs.
        But I guess that makes sense. We could hear CRTs with out ears, now we just need more sensitive equipment.
