Surface dock 2 not connecting to monitors using usb-c cables

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.

    All it took me was new USB-C to DisplayPort cables and it started working every time.

    Could you please post the brand name / photo or link to seller site , of cables that are working for you. I will give it a try buying exact same brand. It's so frustrating experience. Thank you in advance.

    I have bought the Microsoft active adapter USBc-HDMI and it works with HDMI cable. A passive cable USBC-HDMI does not work with the docking station but only direct from Laptop.  https://www.microsoft.com/de-ch/p/surface-usb-c-hdmi-adapter/94CHB2M80S54/58HM?source=googleshopping&ef_id=Cj0KCQjwytOEBhD5ARIsANnRjVhXk4-SGfI3U9_lDkyAJWsiSTzHOo-M_8df0sSOdwgTRwObAGUao4UaAl-3EALw_wcB:G:s&s_kwcid=AL!4249!3!456189990174!!!g!817687661264!&ef_id=Cj0KCQjwytOEBhD5ARIsANnRjVhXk4-SGfI3U9_lDkyAJWsiSTzHOo-M_8df0sSOdwgTRwObAGUao4UaAl-3EALw_wcB:G:s&OCID=AID2100846_SEM_Cj0KCQjwytOEBhD5ARIsANnRjVhXk4-SGfI3U9_lDkyAJWsiSTzHOo-M_8df0sSOdwgTRwObAGUao4UaAl-3EALw_wcB:G:s
