  Hello,

  I've got the USB C Docking Station Dual Monitor,USB C Dock Dual Display 2 HDMI Adapter,14 in 1 Multiport Hub Triple Display 4K HDMI unit.

  I have that connected to my Mac Pro with two Dell S2722DC monitors connected via the 2 HDMI ports. 

  The Mac Pro seems to only see 1 Dell Monitor and the extended display option is selected. Both the Dell moitors are connected and they are mirroring their displays. 

  How can I get the 2nd monitor recognised within the MacOS so that I can extend the display to the second monitor rather than the two Dell monitors mirroring each other.

  Thanks

  Allen

  Dear  @Allen J ，
  Regarding the issue you mentioned, it is limited by the Mac OS itself. The docking station only supports mirroring mode, i.e. displaying the same image. However, if you connect a monitor, you will notice that the laptop and the monitor display different images.
  Please first check the page of the product you purchased to see if it shows support for dual-screen docking.

  Warm regards,
  Sherlock.
