    I have a Surface Pro 4 and just recently purchased the Surface dock. It's connected to two Dell U2412mb 24" external monitors via a pair of cable matters mini DP to DVI cables. I also have a label printer, external hard drive dock, and a wireless mouse and keyboard, all connected through USB, as well as a wired network connection. The problem is..... When I dock the Surface, configure the external monitors the way I want them, then disconnect from the dock, do what I need to do, and come back, the external monitors are set to disconnected and I have to go into the control panel/settings and extend them again. It does this literally every time I dock it. I have a co worker with the exact same setup and his works fine. I'm leaning toward a faulty dock but wanted to reach out to other users here first to see if it might be a simple fix I just haven't thought of. Thanks in advance.

    Additional note: I just discovered that if I disconnect either monitor from the dock and just have one external display, it works as designed, on either one. I would think that eliminated either monitor or the cable as the culprit, so from what I can tell, it's just that when there are two external monitors it is not happy.

    I have to do the same thing if I use the MS wireless display adapter and it usually takes multiple trys to get it to connect so I bought the HDMI adapter.

    This problem used to be horrific with my SB (I have 3 monitors: 2 via DP and 1 via USB). It has vastly improved over time, though, with the various Updates.

    I now consider it a non-issue; however, I still keep a handy utility on my Task Bar to restore the display configurations when the issue returns from time to time.

    So did I, so did I. Then we got the new firmware update and now when I boot up the Surface Pro 3 just flickers like it was psychotic or something. If I disconnect the dock connected mDP monitor turn I get back the monitor connected to the SP3. Every time we have a major update it wreaks havoc on my mDP port in the dock.

    Ok, I believe I've found something that may help many people. I've been experimenting with different cable/connection types and adapters, nothing has really made a difference, that is until today. I didn't have any mini display port to full size display port cables on hand so I purchased a pair on amazon which arrived today. I hooked them up to the existing monitors I've been using and the issue appears to have gone away immediately. I have a co-worker with the same setup who is also reporting that he has not experienced the problem since swapping out the cables either. So..... if you have a monitor or monitors with display ports try these cables below. So far so good for us here.
