I have a Dell Latitude 5400. I'm running a secondary monitor using a HDMI cable that connects to the back of a monitor via an RGB connection.

I will add that this is a work computer and I don't have administrative rights. Not sure if that makes a difference, but there's that.

One more thing: Here's a screen shot of my "Display" settings:
