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.

I assume it is dodgy because it is a 5 meter cable and it was the only HDMI cable to do this, and it was purchased from a bazaar.
