Solved!

External monitor not recognizes after laptop resumes from sleep

HP Recommended
HP ZBook 15u G5
Microsoft Windows 10 (64-bit)

I connected a HP Zbook 15u G5 to the HP Thunderbolt Dock G2 through a USB-C connection. The dock is subsequently connected to a HP Z27 4k monitor through another USB-C connection. Everything seems to be working fine, expect when I resume my laptop after being asleep, the external monitor is not recognized and has to be powered off/on in order to display anything. I already checked for driver updates and even installed HP Assistant, both without success.  I'm running windows 10 version 1909, build 18363.778.  Any help would be much appreciated!

Thanks TryToDoMybest!

 

I had already updated the firmware of the dock, however the OSD menu suggestion was very helpful! I changed the following default setting under Power Control -> Power Mode from Power Saver to Performance which seems to do the trick.

 

Kind regards!
