What I'm asking is to allow the two screens to adapt proportionally to the size of the game window; I mean that even if the window is resized to be twice as long as it is high, the screens height still remains as if it had no room to expand. This is a screenshot with the window expanded across both of my monitors, to give you an idea of what I mean:

Hell, it might just be easier to make the two screens occupy the entire vertical space of the window. This would make it more pleasent to the eyes even if you don't have a fancy setup. Horizontal-split would improve the situation as well, since the average monitor is wider than it is tall.
