Surface Pro 3 dock not detecting external monitor

I found a solution that worked for me...  But have to say, MS, I am frustrated and angry that this isn't solved right out of the box, nor did the fix from MS show up on this thread... or at least the first 4 or more pages of complaints and frustrations. 

Windows and Device updates didn't work, firmware updates didn't work.... etc. etc. 

The solution for me was to download and run the "Surface Dock Updater" ... Really?  We had a dedicated Surface Dock Updater available? Why wasn't the Surface Dock Updater and link not listed as a resolution on this thread?????

Resolution Information Source -- YouTube, definitely NOT MS sourced: 

1)   "How to Update the Surface Dock" -- actual link: https://www.youtube.com/watch?v=MCS3IQrERRc

Resolution Software Download --

1. Surface Tools For IT download -- actual link https://www.microsoft.com/en-us/download/details.aspx?id=46703
2. Note: After selecting Download, you may select only the Surface_Dock_Updater option so that you do not have to download all of the tools

After spending hours on troubleshooting, and even sending a dock back, I finally gave up on MS help, and tried YouTube.  Sure enough,  i found my answer in under 3mins on YouTube and had my resolution in under 10 mins.

Same problem. My old dock works fine for video (tho there seems to be a USB problem).  My new dock, this is my second try at a new dock will not project.

Symptoms:

1. The old dock:

1)displays video properly,

2. indicates / shows two monitors in Display Settings and Identifies them. HOWEVER, selecting Detect Displays shows an error that no other displays are detected.

2. The New Dock:

1. My external monitor indicates "No Signal" -- However, my surface displays in Extended Mode per settings -- If my external monitor is the Main Display, then when i pull up things like the Display Settings the app will not show (ostensibly because it is "displaying" on the other monitor)
2. Plugging my HDMI directly into my Surface allows the monitor to work correctly.

Hi,

My surface pro 3 has not had any trouble to detect external monitor till this morning.

Came back home and tried to connect by using docking station as always I have done.

But suddenly could not be able to detect external monitor.

I have tried all method as I have seen at the community suggestions and solutions, but still failed to detect. All other connected devices on the docking station; key board, speaker, and mouse work fine.

Can anyone let me know what I should do at this point?

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:

• Troubleshoot Docking Station for Surface Pro
• Install Surface and Windows updates

We hope this information works! Please keep us posted!

We are always here to help!

Best Wishes,
