Notebook Video, Display and Touch

**It seems plugging a new dock into a setup that we know already works fixes whatever issue the dock has. After plugging it into a working setup, we can move it to whatever other computer/setup we need it for and it continues to work. Not a real techy solution, but it seems to work.

When trying to use a Displayport to VGA or a Displayport to DVI cable to connect from an HP 2013 Ultraslim Docking station to an external display, the display comes up with no signal and goes to sleep. Connecting with a VGA cable, it works fine. We were able to replicate this issue with multiple new, fresh out of the box docking stations. The issue happens on any monitors that we connect, even ones that work with other docks.

It seems to be the Intel Displayport Topology is picking up the display and making it so that the displayport cannot be activated without connecting 3 monitors.

The older version of the Ultraslim Docking station that only had 1 displayport seems to work just fine, it's just the newer 2013 version that has 2 displayports that has this issue.

Does anyone know if there is any newer firmware or where I can disable/stop the Displayport Topology from picking up this one monitor and trying to make it 3 displays? If not, we're probably going to have to go back to USB adapters and those are no fun.

Thanks,

Andrew
