Surface Dock keeps waking up external monitor

Anonymous

My monitor (LG 29UM68) is connected to Surface Dock -> SP4, via direct miniDisplayPort.

It keeps entering sleep mode and waking up repeatedly, even though my SP4 is asleep. This does not happen when I connect the monitor to SP4 directly.

Another issue is that if I set to PC Screen Only, after few seconds, it will automatically switch back to external monitor only. Again, this does not happen if I connect monitor to SP4 directly.

These 2 issues only arise if I use Surface Dock.

I have gone through all the steps here (https://www.microsoft.com/surface/en-sg/support/hardware-and-drivers/troubleshoot-docking-station-surface-dock) successfully, but issue persist.

Please help.

    That's good info. Even if it did work, it's not a proper solution; my 4k monitor doesn't have HDMI 2.0 (but does have DisplayPort), so I'd be limiting myself to 30Hz (instead of 60Hz) by involving an HDMI adapter.

    Hi all

    Just an FYI, I tried a miniDP to HDMI cable but that did not work with my Ultrawide 27"LG  monitor. The Surface Dock displayed a blank screen. Waste of money buying a new cable.

    Thanks

    I'm a bit surprised at the lack of a response here; we have a considerable number of people in this thread all reporting the same issue. I (and others) have stated that my dock and Surface are both up to date and yet, I still see Microsoft staff asking if that has been done.

    If one of the Microsoft employees who has chimed in here would like provide further debugging, I'm happy to try it. Otherwise, I believe we've exhausted the debugging checklist (update Surface & Dock), and this needs to be sent to a engineer to be further investigated.

    Hi,

    We would like to know more info about your concern. Can you confirm the following information:

    • When and where did you purchase your Surface dock?
    • Have you tried to visit the store where you purchase your Surface Dock so that the store staffs can check it?

    Regards.

    Erwin,

    I know I'm not who you directed you reply at, but I felt that a response was warranted anyway given Microsoft's current handling of this situation.

    My Surface Dock was purchased on 4/26/2016 from Amazon (sold by Amazon.com, LLC, not a marketplace seller).

    I have not visited a Microsoft store with this issue. I did visit an Microsoft store around 6 months ago to have them look at a different monitor-related issue. After they worked on it for over an hour, they were unable to fix it and replaced my SP3 with an SP4 at their expense to resolve the issue. While I appreciate that they made it right for me, I have not been terribly impressed with their troubleshooting skills.

    I have exactly the same problem, ie monitor doesn't go to sleep.

    Note that I have this issue with mini-dp->hdmi cables! This occurs also with only one screen connected to the dock. 

    Pretty baffled by this issue, and even more by the fact that no one seems to care...
