    For a preview that's way way too low touch a dodgy HDMI cable, a finger will suffice if you want to feel electricity and with your tongue if you ran out of 9v bats.

    That's not a dodgy HDMI cable. One of the devices, if multiple are connected together, is causing the mains electricity to be capacitively transferred across the transformer core in the power supply.

    That's a dodgy power supply design because of either a cheap core design, poorly rated decoupling caps across the HV to LV side of the core or lack of earth pin.
