I purchased two new surface dock2 to connect our surface pro 7 to our widescreen monitors using usb-c cables. Neither of the monitors would connect through the usb-c ports.
One monitor is an LG 38WK95C. The other is a Dell ultrasharp U3818DW. The LG monitor previously worked connecting to a macbook pro through the usb-c port.
To be clear, I first connected the surface dock 2 to one of the surface pro 7 devices and connected the Dell to the surface dock 2 through the usb-c. A messages was displayed to the effect that the monitor should be connected through a displayport. The monitor never showed up in windows, although you would get the sound like a monitor was recognized and the displayport message. Using the "detect monitor" feature came back with "no monitor detected".
I then connected the LG to the other surface pro 7 device through the surface dock 2. The exact same behavior occurred.
Windows update showed no updates available. I then manually updated the firmware on one of the surface pro 7 devices. Still no joy.

I have a new Surface Pro 7 and a new Dock 2 with USB C. I have 2 monitors (Dell U2721DE) connected to Dock 2 with USB C and tried all the solutions suggested by Microsoft. The monitors are not recognized. When I connect the monitors directly to the Surface, the monitors are recognized. Does anyone have a solution?
I have the exact same issue connecting my two Dell monitors to the Surface Dock 2. Also tried everything that I could find on the subject.
The strange thing is that when I disconnect the first one, the second starts working. If I plug the first one back into the dock, the first one gets preference and the second one will stop working again.
- Clearing cache made me reset the settings over and over again, but did not resolve the issue.
- I first tried it with usb-c to DisplayPort, and I'm now using usb-c to HDMI, but still out of luck.
- I actually have 2x 24 inch Dell with two different resolutions, because one is actually a touchscreen so I also tried to lower the resolution to match the touchscreen, but that also did not help.
- The frequency of both monitors are set to 60 hz.
Any ideas?
Solved!
I replaced the USB-C to DisplayPort cables we had purchased with some from a different brand and it works perfectly. The original cables shows 4K@60Hz in the purchase description but on the package it shows 8K@30Hz -and didn't work.
I bought a pair of these and it works great.

Yet Microsoft will not address the issue
New Surface with new Dock 2.0
2 new monitors with USB C and no way to connect
I am having the exact same problem with my 38" ultrawide monitor.
I was much happier with the doc 1 and had no problem with 2 monitors. One was a DP and one was a HDMI to DP adapter. I got the Surface Pro 7 solely for the USB C and to not be able to use it is beyond frustrating. I wish I never got the Doc 2 as it worked perfectly, I should have simply found a USB C adapter somewhere. I hope they release a fix because not being able to run 2 perfectly good brand new USB C monitors is pointless and frustrating
