How to connect 3 external full HD displays on HP Probook 470 G5 with HP USB-C Dock G4 (3FF69AA)

How to connect 3 external full HD displays on HP Probook 470 G5 with HP USB-C Dock G4 (3FF69AA)? I found on specification that this dock supports only two displays with FHD resolution. Is it possible to connect third FHD display through HDMI on my HP Probook 470 G5?

All displays have resolution 1920x1080, DVI connectors (so I must use adapters) and I don't need to use notebook screen in such configuration.

Thank you for your quick answer.

After your answer I have decided to buy Dell Universal Dock D6000.

This dock have DisplayLink and have support for my three FHD screens (from specs can run up to three 4K monitors). For output it have 2x DisplayPort and 1x HDMI port.

I have installed DisplayLink driver, connect through USB-C to my Probook 470 G5 and connect 3 FHD screens on the dock.

Problem still occur, I can get 2 screens working but not all 3 in the same time.

When I turn on computer, 2 screens are working from DisplayPort but not from HDMI. If I remove one Displayport cable, dock allow HDMI port and work with remaining DisplayPort. So only 2 screens can work in the same time. No matter where they are connected.

After searching my answer on the web I get a next conclusion. 2 screens work only because of DisplayLink chip in the dock. For third screen dock need DisplayPort Alt mode. I have checked, Probook 470 G5 have USB 3.1 Type-C Gen 1 (Power Delivery, DisplayPort).

Otherwise dock works just fine, peripheral and charging through USB-C work also.

I have tried third screen to connect on my laptop directly through HDMI port. It work just fine together with 2 screens from the dock and this is only configuration that work for 3 screens.

How to get 3 screens working through dock?
