System: Surface Pro 3 i7 / 8GB / 512GB SSD
Microsoft Surface Docking Station
2x HP LA2206x Monitors
StarTech Triple Head DisplayPort 1.2 Multi Monitor MST Hub
StarTech Mini-DP to DP Adapter cable
Plugged in like so:
Docking Station -> Mini-DP to DP Cable -> MST Hub -> Output 1=Monitor #1, Output 2=Monitor #2
The Surface continues displaying on its screen, and Monitor #1 gets output. Monitor #2 seems like it tries to initialize (I hear the "da-dump" sound from the Surface when it gets plugged in/unplugged) but no video output.
I have tested the MST Hub on another laptop (HP Elitebook Folio 9470m) and both external monitors display without issue. The only difference between the two setups is the Mini-DP to DP adapter cable is not required/cant be used for the setup on the 9470m, as it has a full DP port on it.
Any help would be appreciated, thanks!
