Where buy a legit display port 1.2 cable for 2160p 4k monitor?

Solution
You bought the monitor already? It will most likely come with a displayport cable packaged with it, especially if the panel is advertised as a 60Hz panel. The only way to maintain 4K@60Hz is via DP 1.2. You don't need to buy a cable, the display will come with one.
