Connecting additional Display iMac (Retina 4K, 21.5-inch, 2017)

I am trying to connect a Dell monitor to this Mac. (iMac (Retina 4K, 21.5-inch, 2017). No matter what connector I have tried to purchase I do not end up with the correct one.


The only connection on the Dell monitor is HDMI


I am getting really frustrated and very tired of ordering different items to try.


Am I not going to be able to make this work

MacBook Pro, Mac OS X (10.7.5)
