ZDNET's key takeaways

DisplayPort cables are designed to transfer power to monitors.

With cheaper options, misaligned pins may cause power failures.

You can avoid this by opting for a VESA-certified DisplayPort cable.

The DisplayPort "Death Pin" issue, or more formally known as the Pin 20 Problem, is a well-known manufacturing defect in which the last contact pin on a DisplayPort cable is wired incorrectly.

This creates a direct electrical connection between your monitor and graphics card, allowing power to flow freely between them and causing severe damage. And in a time where GPU prices regularly top $1,500, it's best to take every precaution to protect your Nvidia or AMD card from becoming a very expensive paperweight.
