USB Type C SuperSpeed Port

[JMO303]

Was super excited to get my new HP Omni delivered today.  Was then met with let down after discovering that all of these "USB SUPERSPEED PLUS PORTS" are nothing more than high powered outlets.  No Video output whatsoever other than the two Display ports and the HDMI.  I run 6- HP V28 monitors for work purposes.  I tried software, and several different adapters to no avail.   I bought the Omen desktop, number one, for gaming that I keep telling myself I'm going play one day.  Number two I  purchased thinking I was upgrading my office PC and getting rid of an older docking station.  Well, enough back story, my question is, since I can't use any of these USB (including USB C) outputs for video, what is my best bet for running 6 monitors?  Adapter?  Docking station? A second  super high priced Omen desktop?  What type of adapter would be best? Anybody know if the displayport inputs are daisy-chain capable?  (keep in mind I am not running 4k on all my monitors, just three out of the six.  I would be happy just to get them up and running at this point)  

Thank you for your help.
