How to fix screen size for medieval 2 pc

Hi. i recently installed a game to my laptop, medieval 2 total war and i have a problem. Im not sure if this is the correct section to ask, if its not let me know, but the game works fine with no problems, but the screen itself isnt full screen. Its only in the center leaving space on the left and right sides, kind of like when you stretch a page to minimize its size and it leaves gaps. Im not too sure how to fix this because when i play it i cant see to well because it looks smaller and i tried to fix it by looking through the options to widescreen it, but nothing happened. Any help would be appreciated.

I recommend posting on an EA Games or submitting a support ticket with EA themselves.
