HP USB-C G5 Dock unable to display LCD connecting to Fujitsu Lifebook U9310

[PlsHelpIT]

The HP USB-C G5 Dock was working fine with 2 x Prism LCD connecting to a Fujitsu Lifebook U9310, but after switching to connecting to a Lenovo ThinkPad T14, it was still able to work. However after switching back to the Fujitsu Lifebook U9310, it was not able to detect the 2 x Prism LCDs.

The following Troubleshooting have been done
- updating the firmware of HP USB-C G5 Dock
- Tested with HP Elitebook 840 G8 and HP Dragonfly G4 laptop - Able to connect to the LCDs to display
- Tested to connect HDMI connection directly to the laptop - Able to display on 1xPrism LCD
- Tested with another new HP USB-C G5 Dock - also same problem

The issue is that it was able to connect to the Fujitsu laptop initially, it was only toggling to switch between different laptop, then it does not detect the 2 x PRISM LCDs on the Fujitsu laptop. 

Does anyone have similar issue like this?

Does HP G5 Dock only be compatible with certain brand/model of laptop?

@Banhien : As I have highlighted, it was able to connect to the 2 x Prism LCD when it was connected to the Fujitsu Lifebook U9310 for the 1st time. It was only after when the HP USB-C G5 dock is connected to the Lenovo Laptop, which is also able to connect to the LCD. After switching back to Fujtsu laptop to the dock, it is not able to connect to the 2 x  Prism permanently.

Hence if it is not supported, why was it able to be able to connect for the 1st time when it gets connected? 

Thanks for your reply.
