I hate the lock on DP cables since I have managed to break 2 of them when HDMI just slips out in that situation. DVI also has a lock (2 screws) but for some reason their connectors never break, why did DP has degraded that is a very big question for me.
You can buy cables without the lock tabs. They work well and still stay in just fine, making me wonder why the stupid infuriating tabs are even necessary. I replaced all of mine after busting my knuckle open wrestling with a locking cable in a tight space.
