HP Recommended
Product: HP probook 455 g9 and Elitebook 655 G9

I had a problem with an Probook 455 g9 and elitebook 655 g9 with a dock g4 and g5
Laptop clean install windows 11 drivers ,bios and firmware dock up2date.

usb, network works fine but no hdmi of dp port that work.

USB4 Error`s .

After some trouble shooting i found a solution ish.

The bios is on this moment the version 01.13.01 , if you do a rollback to 01.12 and lock it the dock`s work fine.
I hope a new version bios wil fix this problem.

--------------- update ---------------

New Bios version 01.14 works fine again 👍, tested with 455 g9 an a hp dock g5 with 0.18 and 0.20 firmware.
