Hi Mile, thanks for posting. We do not have the MSI WE62 7RJ in our labs for testing and we have not had feedback from customers using this system, so I cannot guarantee compatibility with our docking stations.
In looking at the specifications here --> https://www.msi.com/Workstation/WE62-… they only mention that the USB-C port is USB-C 3.1 Gen 2. While it is possible that this port can support the require DisplayPort Alternate Mode over USB-C, it is not clear if it does when examining the specifications or examining the manual. Based off of this, I would not recommend our USB-C docking stations.
However, I would expect our UD-3900 docking station to work when connected to one of the USB 3.0 Type A ports on your system. Please be aware that our dock relies of DisplayLink technology in order to work. DisplayLink (the manufacturer of the chipset and author of the drivers) has developed a compatibility check tool here --> http://support.displaylink.com/knowle… in order to help determine if your system is compatible with the required software.
If you choose to proceed with a purchase, we offer a 30-day no hassle return policy via Amazon.com/returns if your find that our dock does not meet your needs.
