Thanks All, now using KIWIBIRD brand of adapter for Thunderport to DP, it works, SteamVR automatically prompted me to change DDI too!

I believe the laptop also has "2 ports USB Type-C , you can copy files at USB 3.1 speeds, deliver enough power to charge a laptop or use Alt Mode to send other types of data using DisplayPort or Thunderbolt 3 connections"

I have a Del G5 15 Core i7-9750H CPU, 16GB of RAM, a 512GB SSD and RTX 2060 graphics.  Was informed its specifically for Gaming and OK to use with VIVE PRO EYE.  I can only find HMDI port.  At the risk of looking like I haven't researched enough and need to buy another laptop with the right ports...do I???
