Question about Roline DisplayPort — HDMI (Typ A)

Unfortunately not.

You can see it here, HDMI:

And here for Display Port:

The cable is HDMI 1.2, so it goes Max. 1920x1080 @60Hz. Display port is not specified

You need HDMI 1.3 (or higher, 1.3/2.0 should be enough) and Display Port HBR (or higher, HBR/HBR2 should be enough).

Hope this helps.
