I have a new surface pro 3 and I purchased two docking stations. 1 for the office and one for home. Neither docking stations allows the pro3 to detect a monitor that is plugged into it.   I can plug the monitor directly into the pro3 and it detects if fine both at home and at the office.   I can tell you that its a serious interruption professionally, and personally and does not bode well for MS's desires to serve the business community.   What I need is a solution.

I had exact same issue and I did this and the issue magically solved!!

a two button restart:

  • Power off the Surface Pro
  • Hold Volume Up and the Power button for 10 seconds
  • Release buttons
  • Wait 5-10 seconds
  • Power on the Surface

Hi will-eman,

Thank you for visiting the Microsoft Community! Sorry to know that your Docking Stations are not detecting your external displays. I can certainly understand why this is an inconvenience, especially when, as you mention, it is used in a business environment and for professional purposes. I’d like to help and hopefully provide the best possible solution!

Please try the following:

  • With the Surface and external display connected to the Docking Station, unplug the Docking Station from the power outlet, leave it unplugged for 30 seconds to a minute, then plug it back and see if the displays are recognized.
  • Please make sure all and latest Windows updates are installed. If so, verify all updates were taken while the Docking Station was connected to the Surface.
  • When you connect the external monitor, do you have any other devices connected to the Docking Station as well? And if so, have you tried removing all devices and connecting the external monitor only?
  • Have you tried connecting other external displays to the docking Station? Are ALL displays or devices not recognized?
  • Have you tried the what Ed Bott - MVP suggests?

 Additionally, please read the following support article:

We hope this information works! Please keep us posted!

We are always here to help!

Best Wishes,

    I have an 3' Accell 20276 which is supposedly a DP 1.2 cable, but I just ordered a different one to try.  I'm not sure why my desktop would output to 4k just fine, but not my surface.  It is either the cable or some weird compatibility issue with the SP3...

    I'm having a similar problem outputting to an external monitor from my new dock that arrived today.  I can connect my monitor (Samsung 28" 4k monitor, model U28D590D) directly to my SP3 and it works (although it won't detect the proper resolution.  It maxes out at 2560 x 1440 for some reason).  If I try to connect it through the dock, it doesn't connect at all.  I have all the updates that came out this week.  I have tried connecting through the devices charm (win+p) as well as through the screen resolution window.  Nothing works.  I'm starting to regret buying a 4k monitor and selling all my other ones because the SP3 seems to have some serious issues with them. 

    As a side note, I have a desktop computer that works flawlessly with the monitor (also using displayport), sho there is nothing wrong on that end.

    In order to use/view the full 4K resolution, make sure you have a miniDP cable version 1.2. Version 1.1 won't output 4K resolution. Can you confirm which cable you have?

    I have run my external monitor directly from SP3 OK. When I got the dock today it worked from that OK as well. I don't have all windows updates. The Update for Windows 8.1 for x64-based Systems (KB2975719) fails each time I update.

    This may not have anything to do with your problem. But .....
