Can't play Medal of Honor in fullscreen

[Karlo_9]

So,

When I turn on Medal of Honor Allied Assault (MOHAA),the game doesn't take up all of the monitor.
Some of it (right side) is all black and glitchy. Do anyone knows how to fix this because MOHAA is one of the best games I've ever played and I want to play it again.

P.S. I have a 1080p monitor.

Here is the screenshot I took:
