Cannot get my new HP Pavilion - 14-ce0505sa to output video via an HP L13899 port replicator

[Curves51]

My husband gave me a  HP Pavilion - 14-ce0505sa notebook, HP L13899 USB-C G4 port replicator and Dell 24" monitor for Christmas.

The monitor works OK using an HDMI cable from the HP Pavilion but does not work when the monitor is attached to the G4 port replicator via a Display Port/ mini Display Port cable (supplied with the replicator) or via an Display Port/Display Port cable which my husband uses on his Dell notebook and port replicator. 

We also tried his Dell port replicator and another USB C to HDMI/USB 3 adaptor. However, it did work with a USB2 to HDMI adaptor which my husband had.

I am totally non-technical but my son is an IT support manager and he did all of the testing. When he compared my husband's Dell notbook and this HP notebook in Device Manager the Dell loaded a USB 3.1 eXtensible Host Controller when a USB-C device was inserted and this did not appear on the HP when a USB-C device was inserted. My son searched the internet for a suitable HP 3.1 driver but could not find one. Is this the cause of the problem I am having and if so how can I get a driver for my HP laptop?

From its specs

It does have HDMI port. Have you tried that ? By the way, the dock is NOT compatible with your Pavilion laptop therefore we can't expect to get full functions from it.

There is a list of compatibles laptops on the following link

The response puts the fault being down to the G4 replicator by not having the HP-Pavillion PC on the list of supported PCs.

But the tests carried out by my husband and son put the problem being down to the HP-Pavillion PC. This is because a HooToo USB-C to HDMI adapter did not work on this HP PC. This works OK on my husband's PC. Looking for a driver on the HooToo web site indicates that 3rd party drivers, i.e. Microsoft on the Dell should be used. 

As my original message said the HP PC does not install a USB 3.1 eXtensible host controller when this is inserted which would appear ro be the problem.

It is interesting that the same version of USB 3.0 controller loads on botht he Dell PC and HP PC. This same controller version is also used for the USB 3.1 controller on the Dell.
