Perfect for the price paid and functional on a 4K monitor at 60Hz

I bought to complement the cables supplied with the monitor 4K U28D590D Samsung recently bought because my laptop has only mini DisplayPort outputs.
I am wary of first-price products, so I covered myself by buying a cable, Lenovo. But it works very well and I shall not use the Lenovo if it loose, which will surely happen to me one day as I have to disassemble and assemble the cables for each trip.

For the price paid, the cable seems to me properly made and in any case, it supports quite 4K operation at 60Hz.
The cable I received was the gold-plated contacts, this is not the case of Lenovo, while Lenovo is guaranteed for 3 years.
