Htc Vive Display Port Problem

[AmandaAlts 0]

I got a new HTC VIVE COSMOS and during the setup it need a display port which is included in the box. The problem is that the displayport is too big to fit in any slot in my computer. I have a razer blade 15 btw which has graphics that are VR ready and everything except a display port slot. It has a hdmi port however and I am thinking a mini displayport to hdmi would work but don't wanna waste my money people with the same problem what should I do?
