Thunderbolt docker station G2 USB-Type C Display

HP Recommended
HP Thunderbolt Dock G2 w/ combo cable (3TR87AA)
Microsoft Windows 10 (64-bit)



I am using HP EliteBook 840G6 with HP Thunderbolt Dock G2 w/ combo cable.

I connected to my Monitor LG 43ud79-b using USB Type-C DisplayPort.

The monitor is not able to detect the signal.

If I connect USB Type C cable to my laptop directly, the monitor can run 4K 60Hz. 


Is my docking station broken? Everything is working file, just I can't use USB Type C for my monitor.
