Changing display frequency

I recently bought an LCD monitor to connect to my notebook at work. It's a widescreen Benq with resolution 1440x900 and from the day I installed it my work turned from boring chore into a beautiful pleasure (more or less :) ).

However for some kind of strange reason every time I reconnect the notebook to the docking station, the monitor sets the refresh frequency 60Hz.

Some people say, they can't see the difference, but I'm really not one of them. I really can't stand looking at 60Hz.

Being the lazy person I am, I decided to write a program, so that I don't have to do eight clicks every time I come to work.

After about a twelve seconds of googling, I've found the function I need is ChangeDisplaySettins

Braindead easy program for changing the frequency follows:

#include <windows.h>

int main(void)
{
 DEVMODE d;
 memset(&d, 0, sizeof d);
 
 d.dmSize = sizeof d;
 d.dmDisplayFrequency = 75;
 d.dmFields = DM_DISPLAYFREQUENCY;

 ChangeDisplaySettings(&d, CDS_UPDATEREGISTRY);

 return 0;
}

For convenience purposes binary version follows frequency.zip (5kB).
