I am trying to setup a dual monitor system using a projector as the second monitor, but I'm not having much success.  I purchased a "DVI to 2 VGA Splitter Cable (SW-6095)" from sewelldirect.com, but all the projector will display is the current desktop.  It will not allow me to extend to a second monitor.  In fact the software for the video card will not allow me to enable the 2nd monitor.  I'm wondering if the splitter cable I purchased is not the correct kind or if there is something else I am not doing correctly.  My pc is a new Vostro 200.  I am setting this up in my church, so that's why I'm trying to have the projector as my second monitor.

Any help will be appreciated...
