The 6i7KYK NUC comes with the latest Iris Pro 580 graphics; however, in your case the graphics are handled by the Nvidia GTX 980; Intel graphics are not working.
In regards to your issue, let me know if you already installed the Thunderbolt 3 firmware update.
Plus Razer Core and NVidia drivers
If the problem continues, let me know which devices are connected to the NUC directly and send me results of Intel® System Support Utility.
