I have the same problem updating work to dock 2 with laptop 3 and book 2 - we get 1 or no external monitors - and then it starts working for a while and then stops again and flicks through sources - this is really annoying...
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

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.

2021-07-21T18:13:12+00:00 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
