The USB-C device port on the Dock is designed for Data transfer only not for video. You should use HDMI or DisplayPort ports on the Dock for monitors.
In order to connect a DVI-D monitor to the DisplayPort port on USB-C Dock, an active DisplayPort to DVI-D adapter or cable is required. A regular passive DisplayPort to DVI cable will not work.

Certain devices, including Lenovo’s Thunderbolt 3 dock, may experience functionality issues with active cables (such as our 1 and 2 meter). Please use passive cables instead.
Mac OSX may create an extra 200 MB EFI partitions at the start of a drive hence you may see this EFI partition in Windows. The Windows Disk Management tool can’t delete these EFI partitions, and you’ll see the “Delete Volume” option grayed out. This article describes how you can clean these partitions in DOS command mode and re-format your CalDigit drive.
CalDigit Thunderbolt 3 Docking Stations including TS3 Plus, TS3 and TS3 Lite as well as T4 Thunderbolt 3 RAID are compatible with the Apple Thunderbolt Display (Thunderbolt 1 & 2 versions). Apple’s Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter is required to connect in between the dock’s Thunderbolt 3 port and Thunderbolt 1/2 display.
Thunderbolt Station and Thunderbolt Station 2 are fully compatible with the headphones, for example, iPhone’s or Samsung’s.
If you are connecting from DisplayPort to HDMI/VGA/DVI, please make sure to use an active adapter. Otherwise, please check your cable and make sure that it is using DP 1.2 or higher.
MacOS does not currently support MST, and will be able to mirror monitors at best. If you are experiencing problems on Windows, please make sure that you are using DP 1.2 cables and monitors.
