Can I set up 2 external displays and my internal display?

I have a Dell XPS L521x with Intel 4000 graphics as well as Nvidia GeForce GT640M. I currently only have one external display using the display port and I want to get a 2nd external monitor but I'm not sure if I can. I have read elsewhere that Intel 4000 graphics only supports up to two displays whether or not one of those is the internal display. So since I have a dedicated graphics card am I able to go up to go up another display? If you need more information let me know. Thanks!

I found the answer to my question. I went into control panel and looked at my display setup and my external monitor is using the Nvidia chip so I have expansion room for one more monitor.

Let us know how it turns out
