MST on HP Probook 450 G6

[Noe_TJ]

Hi All,

I'm currently running a UHD Intel Graphics 620 on my laptop that I purchase recently, as you know the Probook 450 has a USB Type-C that outputs Display Port. I'm currently using a docking station that connects to that USB-C and I connect my 2 screens View Sonic VP2468. Both screens have Display Port 1.2 Enabled. I'm trying to update my HP drivers for the graphics but they seem to be the latest. And so far I can only get the second and third screens mirrored? 

I see content in all three screens in this manner:

Laptop Screen (Main Screen)

Second Screen (Extended View)

Third Screen (Copy of Extended View)

Any idea?

Thanks in advanced!

Please describe the docking station. Is it an HP dock?

Hi Huffer,

I'm currently looking at it in more details and it looks like the hub itself is the issue: the one that I'm using is: https://www.amazon.es/dp/B07H2TM2M8#aplus3p_feature_div

as indicated in this graph: http://tinyurl.com/y3tweo83 

The reason why I proceed with MST/Daisy Chain was to use only one of the Video Outputs of the Dock bypassing this mirror limitation. I've purchased a USB Type-C to Display Port and I will try to give it a go, hopefull it works without the dock.

After testing with a cable directly to the laptop (Type-C to DP), I can tell the issue is related to the docking station.

Thanks for your help.
