Looks like you could attach one display with those refresh rates using either USB-C/Thunderbolt or HDMI. That would cut down the total number of displays the Mini could support to two. If you attached another display, that display would need to be attached via USB-C or Thunderbolt and would probably be limited to 60 Hz.
