RezSwitch allows your program to play full-screen on any computer, regardless of monitor settings.

Many games and multimedia programs are developed to fit in a specific window size, such as 800 x 600.  Most monitors are set to a higher resolution than this, resulting in presentations that run in a window (instead of full-screen).

RezSwitch changes the resolution to your desired settings, and launches your executable.  When your program quits, the monitor resolution is returned to the original settings.
