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!

    Buy the DP 1.2 cables. I've found that the DP 1.4 cables do not work with the Surface Docks. Something like this worked for me: StarTech.com 6ft USB C to DisplayPort 1.2 Cable 4K HDR/HBR2 - Reversible - CDP2DP2MBD - Monitor Accessories - CDW.com

    For all those of you coming here to deal with the nightmare of your surface dock 2 with a SurfaceBook 3 and needing a USB-C to DisplayPort Adapter the cable referenced by BeeYang (A display Port 1.2 cable) worked after going through 5 difference cables.

    This seems to be the core issue: The surface dock is not compatible with DisplayPort 1.4 or HDMI 2.0 standards. It uses older technology and anything "newer" in the tech stack means the cables do not work so the dock is a paperweight.

    I set the displayport version from 1,4 to 1,2 and the display worked with the surface dock 2 om my surface pro 5th gen.

    hope this helps more people.
