HP Recommended
Product: Probook 450
Operating System: Microsoft Windows 10 (64-bit)

We have multiple users using Probook 450 some on G4 and most on G5. They all connect to external monitors through HP Elite USB-C G4 docks. After what appears to be a recent update, the Probooks will not display to external monitors. USB ports work normally, and Device Manager recognizes the docks correctly as HP Elite USB-C G4's. This is not happening for all users (yet). One machine was on Windows 10 version 1809 and one was on the newer version 1903.

 

We have tested different machines on the same dock, and the displays work perfectly, so we're left to believe this problem lies on the PC's, and is perhaps a driver issue. We have updated the dock firmware, checked for updated drivers on all devices, but they still do not function. Has anyone else encountered this issue? HP Support had us update PC bios, update dock firmware, but nothing has done the trick. 

 

We are hoping to determine the cause and have a fix before 30 other users encounter the same issue!
