I have a new system with a UD-3900 connected to dual ViewSonic monitors. One monitor is set up with a cable that has a DisplayPort connector attached to the monitor input and a HDMI connector attached to the Plugable docking station. The other monitor is set up with a cable that has a DisplayPort connector at the monitor and a DVI connector at the docking station. Both monitors give “no signal found” indicator nor do they show up as options in the laptop. The docking station appears to be working otherwise. It has power and the laptop recognizes both the Ethernet cable and the mouse dongle connected to the docking station. Is my issue that these cables (DisplayPort to HDMI and DisplayPort to DVI) will not work in this direction or is there something in the docking station not working? I have set up the Displayport drivers on my laptop and it says I am running the latest version of the driver.
