I understand you are trying to get an Intel® NUC for dual monitor configuration. Thank you for choosing Intel products. Let me help you on this matter.
For dual display configuration, you need HDMI or Display Port connections or the USB Type C port. This is what Intel is offering on the NUC7i5 models. It would be a good idea to have the USB type C just a transfer data port.
You can find a list of tested peripherals for the Intel® NUC here
