[solved] Intel NUC NUC7i5BNB Unable to Connect Second Monitor.

I want to connect a second monitor to my NUC via the USB-C port. According to the Intel docs I should be able to connect a display port to the USB-C. However, when I plug in my second monitor it isn't detected. I have tried a couple of different cables. Note xrandr shows HDMI1 as DP-1.

Also if I try to connect a single monitor via USB-C that isn' detected either.

Re: [solved] Intel NUC NUC7i5BNB Unable to Connect Second Monitor.

I am going to make this as solved, but it isn't. After diving into the BIOS I set Primary Video Port to Thunderbolt and Secondary Video Port to HDMI. They were both previously set to Auto. I can't get any output from the USB/Display port using a Display Port cable. However, if I plug in my USB-C  Anker hub, which has an HDMI port I can get output via the Anker's HDMI port. Thus I can now connect two monitors to the NUC.
