Product: HP ZBook Firefly 15.6 inch G8 Mobile Workstation PC (1G3U2AV)

Brand new Z book Firefly 15.6"G8 Mobile Workstation.

Connected to external Dock with two other monitors which previously operated fine with MSI Workstation. Operated ok once then after Windows 11 upgrade connection sent Main Screen (touchscreen) completely blank!

Disconnected from Dock and hard stopped. Re-booted and main screen came back (twice only). 

Connected to dock and all operated as expected. Shut down. Re-started following day, same result as before only this time main screen completely DEAD! connected to single external screen via HDMI port and was able to see to download a windows update. re-booted and connected to dock. Both Screens on Dock operating but main screen completely DEAD!

For this amount of money I would expect a bit more robust machine given it is billed as a 'Mobile Workstation'.  

Dock is Toshiba dynadock U3.0.
