So wait, your video card only has one head (output) on it? Then you run that into a splitter to two monitors but you are projecting one large desktop image?
What you need is a dual-head card where you have one monitor operating as your main, and then another line to the secondary monitor. The secondary line, however, feeds to a 2-port VGA replicator which clones to the projector.
You have your dual monitors, and come presentation time, all you need to do is *turn on* your projector, and it will display whatever is on the second monitor. To me, this is a much better solution than adding a second video card. I'm going to go out on a limb and say if your card lacks two heads then it is probably not too incredibly up to date.. correct me if I'm wrong, anyone.
