Dell Precision M3800 Multiple External Monitors

Hello,

I recently purchased the Dell Precision M3800. My understanding was that it would not require a docking station to show 2 additional external displays (3 total with laptop screen). I was chatting with Dell Support about this but did not come to a resolution...

Is it possible to display 2 additional external displays using the HDMI and Mini DisplayPort outlets?

I can provided more details as necessary. Any help would be greatly appreciated.

Thanks

Caroline
