laptop: HP ZBook 15u G5
dock: Lenovo Thinkpad USB-C DOCK GEN 2
display: Lenovo ThinkVision T24i-10
First time I have plugged HP to above dock (via USB-C) and further to display (via DP) it works well. Display detected automatically. But then I made a mistake and turn off laptop (shut down the system). After turning on I have only laptop display working, additional display cannot be detected, but dock station charge battery via USB-C port.
I have run all of the below internet research solution with no results:
- reboot system
- unplug and plug again all the cables
- roll back drivers
- update drivers (display adapter and monitor)
- remove drivers and re-install (display adapter and monitor)
What is my concern here is if once I turn off and on machine some incomprehensible update takes place to not work with non-HP equipment.
