Kerneltrap has an interview with the creator of project VGA. "The project aims to develop a simple, low budget, open source, VGA compatible video card available this year. Michael is also a member of the Open Graphics Project, but started Project VGA in order to get something affordable on the market as soon as possible."

Because then you are not directly working with a single frame buffer, you either end up shadowing the frame buffer in main memory and have to copy that to the separate buffers in the video cards, or your software has to figure out which card it is drawing to on the fly.
Either method has a lot of overhead.

Well, if your software really has to have direct access to the hardware frame buffer.. But if your app was just an X application X would present all the screens to it as just one large screen and you could render anything you wish and leave the rest to X. Though, I don't have a clue what you're planning so can't really help more than that

Why not just use two separate cards with dual output each? Atleast X can use all the screens as a large single one. Or is it a Windows based project you'd need that for?
