Surface Dock 2 Display Problem

Hi Janette,

Thanks for your rapid answer. No, the exact model of my monitor is C34J791WTU.

I used the USB-C cable provided with the monitor to connect it to the USB-C port on the Surface Pro 7. It works with both USB-C ports on the monitor without any hassle.

The Surface Dock Updater Tool is obviously not present in my computer/ I cannot execute a program file named like this:

But it has created a folder in "C:\Program Files\SurfaceUpdate\SurfaceDock2FwUpdate". Herein are several .bin, a .cat and a .inf file:

Thanks a lot for your further help.

All the best,

Julian.

Hi, Julian!

May we know if your monitor is this one on this link? As for the update .msi files, you downloaded the following and it will not work on your Surface Pro 7 since it tells you that it only works for specific files below, right?

SurfaceDock2_DriverOnly_Win10_17763_20.054.26905.0.msi >>> Surface Go

SurfaceDock2_DriverOnly_Win10_17763_20.054.29700.0.msi >>> Surface Book 3, Surface Laptop 1/2, Surface Pro, Surface Pro 6

As for the SurfaceDock2_SEMMforDock_Win10_17763_20.054.29469.0.msi file, you ran it and have you tried running it after installing?

Press Windows, search for Surface Dock Updater Tool to see if it was installed in your device.

Then follow the prompts when the tool launches.

Can you also tell us which port you plugged in the cable that allowed display directly from the Surface Pro 7?

Regards,

Dear Janette_Z,

thanks a lot for your kind message. Unfortunately, only the file "SurfaceDock2_SEMMforDock_Win10_17763_20.054.29469.0.msi" is working for my Surface Pro 7. The files you mentioned give an error message back:

and:

After I ran the file "SurfaceDock2_SEMMforDock_Win10_17763_20.054.29469.0.msi" nothing happened. How can I check if the update was installed? Do I need to run with admin settings?

Thanks in advance for your further advice and have a good evening!

All the best,

Julian.

Hello, Swiss Julian!

We understand you want to use the Surface Dock 2 to connect your Surface Pro 7 and Samsung monitor. Thanks for the response and informing us that you tried all ports in any way possible. Can you try to download the Surface Dock 2 update manually? Please go to https://www.microsoft.com/en-us/download/details.aspx?id=101317 and select either SurfaceDock2_DriverOnly_Win10_17763_20.054.26905.0.msi or SurfaceDock2_DriverOnly_Win10_17763_20.054.29700.0.msi

Let us know how it goes.

Hi Janette_Z,

thanks a lot for your kind answer. i really appreciate your assistance!

I indeed forgot to mention that I also tried both USB-C ports on the Surface Dock 2 and both ports on the monitor as well, in each possible combination 👍

I also tried to update the display drivers with the latest version from Intel‘s homepage, and I also tried it with the drivers for the monitor.

BTW, as the dock arrived this morning, it showed up no update in Windows update.

I hope you can now isolte the problem even further and provide a solution quickly, as I would love to use my big monitor with the Surface Pro 7 in my homeoffice.

Have a great evening, take care and enjoy your weekend!

All the best,

Julian.
