AFAICT the video interface is irrelevant. It exploits the data transfer between the CPU and RAM. > When data moves between the CPU and RAM of a computer, radio waves get emitted as a matter of course. Normally the amplitude of these waves wouldn’t be sufficient to transmit messages to a phone, but the researchers found that by generating a continuous stream of data over the multi-channel memory buses on a computer, they could increase the amplitude and use the generated waves to carry binary messages to a receiver.
