Surface Dock 2 Display Problem

Dear Microsoft-Team,

Dear Community,

I recently got the brand-new Surface Dock 2 for my home office. I try connecting it with my Surface Pro 7 and a Samsung C34J791 (LC34J791WTUXEN) monitor with the supplies USB-C cable from Samsung which came with the monitor.

Windows is recognising the monitor fine, it shows up in the screen settings.

But the display is not showing any images, it just keeps switching through the inputs to find a proper signal and after some time the monitor goes into sleep mode as it could not find a signal.

If I now connect the display to the Surface Pro 7 directly with the same cable it works just fine and I can see the desktop on the Samsung monitor.

What do you suggest?

Thanks a lot in advance for your kind assistance and have a great weekend!

Best regards,

Julian

    Hi, Swiss Julian!

    Thanks for reaching out to Microsoft Community and posting your concerns. We are sorry to learn that your Samsung monitor will not show a display when connected to your Surface Pro 7 via the Surface Dock 2. Thanks for taking the time to let us know about this and allowing us to help you out.

    Thanks for noting that the monitor works fine when directly connected to the Surface Pro 7 using the same USB-C cable that came with the monitor. That helps us isolate the issue here. If I may ask, did you try all USB-C ports on the Surface Dock 2 to test which would work? Also, please ensure that either of the 2 ports in the back are the ones you plug in your cable. Kindly try plugging in the cable to either of the 2 USB-C ports located at the back of the monitor as well. See which of them will work with the USB-C display ports as shown below.

    We hope this helps you out. Otherwise, don't hesitate to respond to this thread if there’s anything else that needs to be addressed. 

    Kind regards,

    Janette_Z
