Medal of Honor Allied Assault Spearhead Keeping Resolution, Not Stretching to Fullscreen

[The Squire of Suck It]

Game is running at 1920x1080 in windowed mode. My monitor is 3440x1440 and I would like to stretch the game to the entire screen, not just the bottom left corner.

A bonus would be "keep game ratio" (which would be 16:9 instead of the stretching the width to the monitor which is 21:9).

Did you find a way to solve it?
Mine was running fine, but as I reinstalled it, I started to have this same problem.

Thanks in advance, mate ;)
