Bests & Worsts Reviews from Amazon

Cable works as described, but note that it is uni-directional. It will work with DisplayPort as the output and HDMI as the input. It is described this way as well, but my intended use case was the opposite. I've never heard of a one-way translation for digital video signals, but that does appear to be the case. I verified this worked fine from a Dell docking station (DisplayPort) to a Dell 4K display (using HDMI input). Using the DisplayPort input on the monitor and HDMI output on a laptop did NOT work. Not deducting stars from the rating due to my lack of knowledge on the reverse not working, but writing this review in the hope that it prevents someone else from encountering a similar issue.
