wrapping tinfoil around an hdmi plug/cable isn't particularly hard either :) chips are harder but at least you rule out the cable. HDMI cables are ridiculously finicky if you've ever tried to get anything more than the lowest common denominator 1080p going on them.

I don't agree that wrapping foil is a great way to 100% rule that out as there is room for error. Using different cables/dongles would be better and they already tried that.
