HP Thunderbolt Dock 230W G2 video issues

Hi everyone,

I'd just bought a MBP 14" M2 Pro. I also have a HP laptop for my work. I use both computers with and HP usb-c dock using display-link to use and external display. Both computers work fine and I can use a second display.

Now I've got a HP Thunderbolt Dock 230W G2 with combo cable. The HP laptop works seemsly with the second display.

When I connect the MBP the system recognize the second screen, but the video is not displaying and the monitor goes to sleep mode, while still running in background (the mouse pointer travels to the other monitor as it is were on).

I'd updated the firmware of the dock but still the same problem. Everything else works in the dock. The ethernet connection, the attached hard drives ...

Any clue? any hint?

Thanks in advance.

Kind regards.
