@lanodan@queer.hacktivis.me if you're using vga or dvi, you only have one monitor, and i know approximately where in your home your computer is, font size would likely not be an issue for me (once i figured out your resolution and refresh rate)

confound any of those, and it probably would be. i got enough out of an HDMI stream to recognize my desktop, but not read text in my terminal. but i'm also just a random transgirl with a cheap SDR who was doing a personal risk assessment with open source tools plus something i hacked together myself, in order to sate my curiousity and light paranoia/ocd

i'd say there's a few ways of looking at it, and where i sit is: the fact that i can get that far without much effort is worrying, and a three letter agency has a lot more time and resources they could devote to things like "writing a proper hdmi/displayport decoder with an sdr backend" or "figure out the signal processing bullshit you need in order to separate two display streams". simultaneously, i would be baffled to learn that they were using that against me.
