docking station and monitors

I know i've seen a few posts here but I can't quite figure out what I need. I just started a new job and have a dell inspiron 14 2-in1 Model 7145

I have a docking station - USB 3.0

I absolutely can't get the monitors to work. I have 2 and neither the HDMI or the other connection is working. Could someone please tell me what I need to get this set up.
