Review on 🔌 Rankie DisplayPort to DisplayPort Cable: Enjoy 4K Resolution Clarity - 6 Feet, Black by Kyle Merriman

These Displayport cables are NOT VESA compliant. PIN 20 ACTIVE! This cable sends 3.3V on pin 20 from the monitor back to your GPU. This can kill the GPU over time. Most integrated GPUs will detect this and your motherboard will not send a message. If you already have this cable or want to test your current one, you can turn off your computer and a fan or two will continue to spin or the LEDs will dim as the monitor feeds power back to your system. If you unplug the cable, it stops.
