Hello, the MINIS PRO just can connect two monitors, do not support connect 3 monitors.
You can have a look about other machine can support 3 monitors, such as SER 5800 MAX-----https://www.bee-link.com/catalog/product/index?id=513
This is not correct. I was able to connect 3 monitors by using hdmi to usb for video adapter. It works great! I have 3 monitors running in extended mode with no issues.
Ok, it is fine if you can work with 3 monitors by using HDMI to USB for video adapter.
What I am saying is that the MINIS 12 PRO just has 2 HDMI for displaying.
