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

This is the advertised @4k compatibility but using my Samsung E28D590 I couldn't get a resolution higher than 2560x1440 and even then it was buggy. When changing to a different cable, the problem disappeared. If you just want to run a 1080p display that's fine, but if you want 4k you'll get something else - watch out for the DP version it claims and try to get one that supports DisplayPort 1.4 compatible, even if it may seem excessive. and costs a few euros more.
