After setup and troubleshooting emails from Johnny @ CKL. It works like a charm. Beware of DP-HDMI cables. I had one that worked on an HP workstation and another of exactly the same type that didn't work on a Dell Latitude. Johnny recommended a short unidirectional DP male to HDMI adapter and it worked flawlessly. Remember that all USB to HDMI adapters are mainly for USB3. CPU ports and only shows 800x600 on a USB2 CPU port. Once completed it works like a charm and my client is delighted.
