C2G Legrand DisplayPort 1.2 Male to Male Displayport Cable, Black Display Port Cable, 35 Foot Digital Display Cable, 8k Display Port, 1 Count, C2G 54405 Male to Male Cable 35 Feet

It seems like a durable cable. The connector lock mechanism is better than a lot I've seen. Having a variety of cable lengths to choose from when shopping is very valuable to the customer in my opinion.

Horrific quality cable. Good connection to my 4k display the first day, then, I started getting flickering and cycling through signal loss, constantly. I know it's the cables because when I even move the cable slightly, coil it for instance then plug it in, the occurrence of the signal problem changes, maybe even temporarily disappears, but later re appears. When I use the HDMI ports on my monitor, and even the Displayport using another cable, no problems whatsoever. Very unhappy. It's practically useless. I want my money back.

If you are reading this, you know how rare 50ft DisplayPort cables are and that most cables this length do not have the 12.7Gbps of bandwidth to support 1440p at 144Hz. Lucky for me I was able to get this cable for $65 from Amazon Warehouse Deals and to my surprise it does run my ASUS ROG at 1440p doing 144Hz with G-Sync and that is exactly what I was looking for.

Very disappointed with this DP cable, the picture quality is impressive (it was connected to an ASUS VG248QE monitor), but the cable lasted 2 months and died (I did not even move or unplug the cable until they died)

These cables support 4k/60hz from a GTX1080 to two Dell P2715Qs without issue. The other cables I tried in one case did not allow 60hz and caused the PC to have trouble booting. The other with the wonderful Pin 20 issue caused a power surge that required me to replace the aforementioned GTX1080 due to its being dead.
