I always thought it requires a CRT screen, but I got a surprisingly clear signal from my LCD screen.
Why does this work? Where does the recoverable signal leak? I would expect a modern LCD to be full of digital signals sent in unpredictable, manufacturer-specific ways, and certainly not sequentially enough to leak as recognizable audio.
