How to write RGB information on the VGA port of 32 bit system.

Hi,

In my latest project, I am required to send some data through my VGA port. When the external monitor is connected to the Laptop VGA port the full laptop screen is duplicated and displayed in the external monitor.

But my requirement is that, I need just 320x240 resolution of video to be displayed on the external monitor i.e. I have to write the data to the VGA port or some alternative

I am developing the application in VC++2008. Is there any convenient way to perform the task.

Thanks...

This would probably mean writing a video driver or filter. You should refere to the Windows Driver Development Kit for details.
