Surface Pro 3 external monitor / display port issues

I know many people have been having issues with external monitors and the displayport connections on the Surface Pro 3 and Surface dock.  I've been having some issues too, and thought I'd share my config / workarounds in case it helps. I believe the issue is fundamentally with the Surface video drivers getting confused, not the docking station. 

My explicit questions are: Is there an easy way to force it to detect new displays?  Anybody have any other suggestions on how to resolve this?  Is there some way to open a formal technical ticket with MS?

My hardware: Surface Pro 3 i7, 256 GB; Surface docking station, 2 HP Z24i displays (1920x1200 resolution each), StarTech Mini DisplayPort 1.2 to Triple Head DisplayPort MST Hub (StarTech PN# MSTMDP123DP)

It's setup as follows: Mini DisplayPort MST Hub plugged into back of docking station, HP monitors plugged into ports 1 and 2 of the hub.

I've had this setup running for about 2 weeks. At first I couldn't get it working, but with the last firmware update in mid August it started working fine.

HOWEVER, just this week I've had issues where I can't get the Surface to detect the displays / output to them when I first plug in to the dock in the morning OR sometimes when it's waking up from going to sleep (like at lunchtime). No amount of fiddling / plugging / unplugging things seems to consistently fix it.  The 'Detect' button in the Screen Resolution window doesn't help.  Doing a shutdown / restart of the Surface also doesn't consistently work. Note that when the Surface gets like this, even plugging the Hub directly into the mini display port on the Surface itself (with it not docked) won't work.

The reason I believe this is a Surface / Windows issues is that when it gets into this state, within the screen resolution settings in windows it often thinks that there is another active display plugged in and will act as such (e.g. lets me extend or duplicate the desktop) - even if I have the surface completely undocked, not plugged into anything. Specifically it says it is a "Display device on: Mobile PC Display" with a resolution lower than 1024 x 768.  See pic below.  This state often survives through a reboot of the Surface.

The general process I usually get to work after a couple tries:

-Use Windows-P keys to set the surface to use only the internal display

-Shutdown the surface and undock

-Unplug the dock and hub

-Plug hub back in

-Power Surface back up while undocked and login

-Dock surface

-Plug dock back in

-I'll know it works at this point because the displays will automatically come on (no need to use windows-P key to toggle them)

NOTE TO FORUM MODS:

Before you reply with your standard questions, know that I've already done all the normal things, including shutdown, check all cables, all updates installed, run the hardware and devices troubleshooter.  I've also checked related threads, such as: http://answers.microsoft.com/en-us/surface/forum/surfpro3-surfdevice/external-display-flicker/1e2b9154-0533-4137-880f-55a90d2d6659?page=1&tm=1409850909719 (Note I've never had an issue with flicker) and http://www.surfaceforums.net/threads/mini-displayport-on-new-docking-station-doesnt-work.10577/ (This isn't an active vs. passive adapter thing.)  Once I get it working it works just fine until the surface undocks or reboots.  It's clearly an issue with Windows / Surface not properly detecting displays.

    Glad that worked for you too. Hopefully MS will iron out the remaining bugs in the coming weeks..

    Thanks Andy!

    That worked - the display had "Disconnect this display" selected in the drop down instead of "Extend to this display".

    Cheers

    Thanks Andy

    I wasn't aware of that, so I'll give it a go when I get home tonight.

    For those still having problems on Windows 10, have you tried to "force" Windows to use your eternal displays using the old control panel? I have noticed that sometimes the displays are not detected and cannot be activated using the new Windows 10 display app, but they can be brought back using the old control panel display app.

    If you don't know how to find this then:

    1. Right click the desktop and select "display settings"
    2. Select "advanced display settings"
    3. From this screen select "advanced sizing of text and other items"
    4. This will bring up the old style display app, select "adjust resolution"
    5. Now click on each display and manually force it to extend the desktop to that display. Make sure you click "apply" after changing settings for the first display before doing the same to the second.

    I have found that sometimes this is the only way to get the screens to be detected when I get an occasional glitch, which is about once a week. The external displays then remain connected following a reboot. 

    Hope this helps at least some of those having problems..

    I had two displays, one plugged into the dock, the other into the surface, working fine with Windows 8.1, but since the Windows 10 update I can only use one of them. Doesn't matter which one, if only one is plugged in, it works, and it doesn't matter where it is plugged in, it works, but the moment I plug the second in, the one on the docking station turns off and can't be detected.

    Looks like they have fixed the problem with using a display hub, but have now broken something else.

    Guess I might as well go out and buy a hub rather then wait for a fix..

    Incidentally, I have the same set up at work, and it still works fine.  At home, it worked initially, but the first time my surface went to sleep whilst plugged in to the dock, it woke up and has been in a grump ever since.
