    Hello dear community,

    it is the first time that I ask a question in a forum like this because normally I can find all the answers to my questions on google or forums like this but not with my current problem.

    My setup:
    Surface Book (manufacturer number: CR7-00014)
    Surface Docking Station (man. nr.: PD9-00004)
    Asus VS278Q or Samsung U28E590D (man. nr.: LU28E590DS/EN)
    Available adapters/Cables:
    - Active mini-DP to HDMI adapter (man. nr.: CAC-1070
    - Microsoft mini-DP to HDMI adapter 1553
    - HDMI 2.0 or 1.4
    - mini-DP to DP cable 1.4
    - Plugable USB 3.0 Dual 4K HDMI 2.0 Adapter (man. nr.: USB3-6950-HDMI)

    My problem:

    Since I've bought my Surface Book 1.5 years ago, I've never been able to connect a external monitor through my mini-DP port. In the assumption that my mini-DP port was defective, I've bought a Surface Docking Station and tried to connect through one of those two mini-DP. Same result - no secondary monitor detected.

    When I connect it with the Plugable adapter and the HMDI cable, the monitor receives a signal but I can't work with it because there is too much lag as the Windows Driver Foundation is eating around 40% of my CPU.

    What I've tried so far:
    General:
    - Installing newest Windows Updates
    - And yes I've checked the display settings on my monitor and if the cables are plugged in correctly.
    - Tried connecting the Surface Book directly to one of the monitors by using either the mini-DP to DP cable or the active mini-DP to HDMI adapter with the HDMI cable. Also tried the same with the Surface Docking Station.
    - Tried my setup (Monitor and Surface Docking Station) with another Surface Book - It worked perfectly

    Display adapters:
    - Updated the two display adapters with the newest drivers available (Intel HD Graphics 520 (Driverdate: 23.09.2017, Driverversion: 22.20.16.4811), NVIDIA GeForce GPU (23.01.2018, 23.21.13.9077)
    - Uninstalled the display adapter drivers, rebooted my system and installed all the drivers again

    Surface docking station:
    - Docking Station is charging my Surface Book when plugged in and my sound system also works (connected through the 3.5mm audio port)
    - Cleared the display cache by running the surface dock registry.reg.
    - Tried to update the firmware of the Surface Docking Station with the Surface Dock Update (Surface_Dock_Updater_v2.12.136.0.msi) but this updater always ends prematurely.

    What I haven't tried so far:

    One of my last options would be a complete factory reset of my Surface in the assumption that one of the installed programs causes this problem. I do not like this option because it would cost a lot of time to install all my programs again and it is not guaranteed that it would work.

    My questions:

    - Does anyone has or had similar problems? Could you solve them? And if yes, how?
    - Apart from reinstalling/updating the display adapters, what else can I do? As it is not working either with or without the Surface Docking Station, I assume that the problem lays with the Surface Book itself.
    - Is there a possibility to reduce the amount of CPU used by the Windows Driver Foundation? If I can reduce this amount, it would be an acceptable workaround.

    Thanks for your help and best wishes

    Cedric

    I do not have a Surface Book but I would suspect the mini DP / HDMI adapters as one doesn't work and the other is slow. From what I read you have tried them from both the SB and the dock with the same result. I would try a different cable or adapter.

    Hi EHoskinson

    Thank you for answering. I've already tried multiple adaptors/cables but none of them worked. I've sent the Surface Book to a repair station and they said that my port was defect, that explains why another Surface worked with my setup and mine didn't.

    Thanks anyways and best wishes.
    Cedric
