    NUC7i7BNH – Dual Monitor Output via a Single USB-C Port

    Erez

      Hi,

       

      My monitor setup is as follows:

      • Samsung C34F791 (3440x1440 resolution)
      • Samsung S27A650D (1920x1080 resolution)

       

      Both of these monitors have a DisplayPort input. I’d like to connect them via this port to my NUC7i7BNH. The USB-C port on the back of my NUC7i7BNH supports Thunderbolt 3, but I’m not sure if it’s capable of driving this dual monitor configuration.

      Some suggest to use an external adapter, like Cable Matters, StarTech, or plugable.

      - I read that “USB-C specifications only allow one external display per USB-C port”. Is this correct for NUC7i7BNH’s Thunderbolt 3 port as well?

      - If so, doesn’t an external dual DisplayPort adapter like Cable Matters adds latency or reduces framerates?

      - Would you recommend using a single USB-C port and an external dual DisplayPort adapter, or direct USB-C to DisplayPort connection on one monitor + HDMI to DVI connection on the other monitor (S27A650D doesn’t have HDMI inputs)?

       

      Regards,

      Erez.
