[NAME]  The instructions are probably correct if you had a display that had a DisplayPort input, in which case the dock’s DP output could send a DP signal. But that isn’t what you’re doing. Dual Mode DisplayPort is an optional capability on DP outputs. But an active adapter will allow your dock’s DP output to send a DP signal as it normally would, even if you’re not ultimately sending the signal to a DP input. Good luck!
I have a new Dell XPS 13.4 - just got it! I want to have it drive two monitors. I have a Vision Tek VT2000 MST docking station and connect my primary monitor HDMI-HDMI and it works fine. The docking station is connected to the laptop via USB-C (only option). My secondary monitor is connected DVI-Display Port and it is not detected. (On my old MSI laptop this monitor was connected via DVI-mini display port and it worked fine) If I connect the primary monitor alone via DVI-Display Port it is not detected either. Could the Vision Tek Display Port ports not be working? It is a brand new MST Docking Station. The DVI-DisplayPort cable is also new. I think it is passive - I noticed in my searches some advice was to use active. Before I spend more money trying to get this to work I thought I'd ask here. Any advice? Thanks!
