Wow. I think I am going to build a test device for this. It would be very simple: Two female DP ports with pins 20 wired together through a battery, resistor, and LED. For good measure, it should be four ports so we can test mini-DP as well. If the bulb lights up when you plug both cable ends in, then the cable is bad.
