Dual Display

[Sunny]

Hi guys..

I have configured a dual monitor setup on windows XP (extended
desktop). Now what I want is to have an identical display on both the
monitors.
the Nvidia GeForce4 MX series supports "Clone mode" which gives
identical outputs on both monitors.
I can change the modes using display properties..settings.
My application needs both the "clone mode" and the normal extended
desktop.
So is there any way that I dont have to manually change the display
modes and through some script or program I can automatically change
the display modes ?

Can I call this script or program through a browser ?

Waiting for replies..

Thanks
