Help please guys

TLDR: Set up htc vive pro on alienware m15 r6

Hi im trying to get into the vr gaming scene so i purchased a new laptop alienware m15 r6 and htc vive pro This setup cost me £3000 and i have spent the last 3 days trying to set it up but its not working i get multiple errors On steam VR.

I have tried it with dvi to hdmi cable and also with the original dvi to usb c My laptop doesnt have a dvi or mono dvi port so only the hdmi port or usb c port to work with.

Any help would be appreciated or im afraid ill be selling the headset.
