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

    I had the same problem. In desperation, I tried everything and finally it helped to run Surface Diagnostic Toolkit and in the step where the program tests the touch screen, it apparently restarted the settings and popped up the second monitor.

    Configuration: Surface Book 4 (Intel), Surface Dock 2, EIZO CS2730 connected by USB-C to HDMI cable.

    Same problem with my C34J79 Monitor. Works fine when I connect the monitor directly to the DP/USB-C on my Surface Book 3. However If I go via the Surface Dock 2, it doesn't work.

    Very incredibly broken and annoying that this hasn't been fixed in over a year!

    Well finding USB C to HDMI without Thunderbolt compatibility seems to be a challenge.

    Might just risk and just buy a monitor that has USB C connection as well.

    Update

    Samsung LC34H890WG, connected with USB-C works just fine.
