Alienware Aurora R5 question

[McRecon]

I have an Alienware Aurora R5 that has an Intel(R) Core(TM)i7-6700 CPU @ 3.40GHz with 16 GB of RAM. I am running Win10 on a 64-bit operating system. I need the ability to use two monitors at the same time, but I cannot find how to use dual monitors in the Settings. I can use split screens, but need to use two monitors. Will this computer allow me to do that or do I need to get a new computer?
