This guy stole a 5yo video from @TahaOrsel and cut off the intro that showed a hackRF plugged DIRECTLY INTO a tap on the HDMI cable.
There is no “distance” here.
Here is the intro that was cut:
@Psalteric@_MG_ Confirmed. It would have been much better if you had done it in the first place, but I dont make a big deal of it. What is important is that you made my video reach a much wider audience than I did on Reddit alone, so maybe more people will get sparked by their curiosity.

@_MG_ By tapping, I meant tapping the signal wirelessly. There is nothing else except an antenna and the HDMI cable, as seen in the intro. It is completely wireless. I think what caused the confusion is that I put the antenna directly onto the cable. They are not connected by any means
@_MG_ Works actually pretty well. I dont have any footage of the further distance but if i find the time i will do it and also explan the process.
For the people who want to research it, its called TempestSDR. The phenomenon is called Van eck Phreaking
Thanks for defending me btw.
@aean0x@Psalteric You cant imagine how shocked i was when i saw my office while doomscrolling twitter. The video is mine.

your HDMI cable can leak what’s on your screen
watch the laptop on the left. it reconstructs the video playing on the monitor beside it from radio signals leaking out of the HDMI connection
this is TempestSDR. an antenna picks up the leakage, a HackRF radio captures it, and software turns it back into an image
researchers took this further with Deep-TEMPEST, using AI to make recovered images and text easier to read. this clip shows the original technique
quality depends on shielding, distance and interference. the picture is imperfect, but recognizable content still gets through
a wired connection can still leave a wireless trace
@Toki_Kurumsal Anne-Baba üzerine mal olunca genç kontenjanından katılamamak ne kadar saçma bir durum. Resmen gençler katılamasın diye koyulmuş bir şart.
@MacroWorld21@grok the first image looks like it could have some coupling capabilities like a transformer. Can you explain?
For thr second image i am thinking of something like directional antenna. Are they reflectors of some sort? Or since the circuit is so small maybe they are for empedance
