No whistles here

A typical demo of this technique does it this way: You’re sitting at your PC happily looking at something (like in (1)). Guys sitting almost 25m away (not in direct contact with you) can reproduce your entire screen (like in (2)).

What’s this technique called?

It isn’t new, BTW. A proof-of-concept was published by a Dutch researcher in 1985. (The technique was eventually named after him)

Answer: The process of “eavesdropping” on a monitor from far away by reading the EM signals emitted was called Van Eck phreaking, after Wim Van Eck, the scientist who first invented the method.

    Van Eck phreaking is the process of eavesdropping on the contents of a CRT display by detecting its electromagnetic emissions. It is named after Dutch computer researcher Wim van Eck, who in 1985 published the first paper on it, including proof of concept. Phreaking is the process of exploiting telephone networks, used here because of its connection to eavesdropping.
