If your goal is to feed two external monitors, you would be better off with a higher-end system.  If you're within the return period for your system (30 days from shipment if purchased direct from Dell), contact customer support for a return -- and order a system with Thunderbolt support (5000 series and up with the Inspiron line;  XPS, etc. also support Thunderbolt).  
I purchased an Inspiron 15 3000 not realizing it does not have a USB Type C Thunderbolt connection, and now do not know how to connect my docking station (WD19TB)  so I can utilize my dual external monitors.
