U2715H, Microsoft SurfaceBook, Microsoft Surface docking station, disconnect issues

Take the dock out of the troubleshooting and re-test.

SurfaceBook mDP out --> mDP to DP cable --> #1 U2715H DP in (DP 1.2 ON)
#1 U2715H DP out --> DP to mDP cable --> #2 U2715H mDP in (DP 1.2 OFF)

Hey Chris,

Thanks for the reply and sorry for the delayed response.  Yup, taking the docking station out of the equation verified that there seems to be an issue with the docking station itself.  I have been running the two monitors in a daisy chained configuration since Monday (four days now), and these issues are no longer happening.  I already have tickets open with MS.

They told us awhile back that they were developing a special power connector dongle that addressed the same issue with their Surface Pro dock. We have not heard back from them.

For the past few weeks I've been battling with inconsistent monitor performance with my new Microsoft Surfacebook.  I initially started to troubleshoot with them to track down what the issue was.  After some updates (a big one today), I'm still having these issues.  Initially I posted about this here:

http://en.community.dell.com/support-forums/peripherals/f/3529/p/19659756/20843820#20843820

encountered some blanking out issues even without the docking station, although it seems to be less frequent.

guarantee the performance.

Monitors are the last peripheral that I thought I'd ever have a problem with.  There's probably not going to be any real solution from either company for this bizarre incompatibility. I'll have to sell these off and hope I can find monitors that are compatible?  And then do I buy Dell monitors again or worry that they'll be incompatible (or the Surface be incompatible with them, I guess you could look at it either way).

So annoying.

Where did you get that chart?

Can you forward that email to me? Our Displays Team needs to discuss this with Microsoft.

Has there been any progress on this?  I just got a Surface Book and was a bit surprised to find my pretty new Dell monitor on the list of unsupported monitors.  Currently it is working using a mdp-dp directly from the Surface Book, but I've been unable to get it working from the Dock.  I have ordered the MS recommended cable (active mdp-dp) hoping that it will work from the Dock.  

I was able to get both monitors working in an MST configuration plugged directly into the Surfacebook.  Around Christmas, I had my book swapped out for another and have had fewer problems with it but even after that swap, I was unable to get it to work in the docking station until recently.  About a few weeks ago there was a firmware update that seemed to address the issue and I've been using the monitors in an MST configuration through the dock, and it is, for the most part, stable.

It's not perfect, though. At times when I plug into the docking station first thing in the morning, the monitors don't always come up or only one turns on. I have to unplug the monitors from the docking station and back in, and sometimes power down cycle the monitors by unplugging them.  Fortunately this doesn't happen very often.

Ultimately, I the Dell monitors are fine and are not the problem.

You may take a while to get the monitors working through the docking station but it should be possible.  It's definitely more of a pain than it should be, but hopefully more updates will come down the pipeline making it less of a hassle.

Is there a way to turn off the power save setting on the monitors so the monitors do not go to sleep?  I cannot find a setting for that. 

Hello, I use my personal Surface Book for work with a DEll 2715 connected via SurfaceDock and have the same issues particularly with the Surface Book going to sleep and then the Surface Dock disconencts the monitor.  I asked for our IT department help with MS for support here, I was hoping the most Surface Dock firmware would solve the issue but it hasn't.  Since this is a fairly popular display, I hope Dell and Microsoft can solve this.  I have to say I never get such issues with the Lenovo X1 Carbon Gen 3 and its dock connected to this monitor...

I have the same issue with 2x U2715H monitors each connected via the mDP to Surface Dock (new brick one) and Surface Book (with the NVIDIA GPU). Can't get both monitors to work stable. Constant sync issues with the Monitors dropping and going into sync loops. I have tried 1 monitor directly to the Surface Book via mDP port on machine and works fine.

Is there a known reason why the monitor doesn't work. It is listed on Microsoft site as in-compatible.

Interesting enough, I have tried a Surface Pro 4 and it works fine in the same Surface Dock configuration. Have to think its something with the Surface Book. Have swapped out the Docks couple of times now with same results.

Has there been any resolution on this? I find that trying to use a U2715H with Surface Book through the Surface Dock causes the internal display & the 2715H to repeatedly turn off & on, making the display completely unusable with the dock. The display does seem to work correctly with the same mini-DP cable connected directly to the Surface Book instead of the dock, however that prevents use of the dock because of size of the dock's connector.

I contacted SurfaceCustomerCare@microsoft.com about the matter but as I was running a Windows 10 14xxx build instead of 10586 they were unable to help further, suggesting only that I go back to 10586, as if that would somehow correct the problem... it sounds like the problem exists aside from 14xxx based on this thread, and SurfaceCustomerCare@microsoft.com is not aware of continuing incompatibility.

To start, the Surface Docking station firmware needs to be checked, and if old, updated.
