Tangentially related: once I bought a no name Amazon HDMI switch that would cause FM interference but only when the screen was mostly white: https://youtu.be/n2DPLEvwO-k
What's interesting is that HDMI is supposed to have a scrambling system that prevents any repeating pattern from causing EMI. I wonder if there was an unshielded, unscrambled raw data path somewhere in the switch.
