Question about Roline DisplayPort — HDMI (Typ A)

which cable would you recommend me to connect a Macbook Pro 2015 with an Eizo monitor? On the Eizo it has a DP port.... Unfortunately, I first ordered the wrong cable (monitor HDMI and source display port), but of course it doesn't work because it should probably be the other way round... I'm a bit overwhelmed at the moment. A few suggestions by email would be great. Thanks a lot
