How do you split an image or video from a source such as a dvd or computer to fit more than one screen or projector? I am wanting to know this because I am wanting to use two projectors to display one image, and also switch between dual and single. I do not want to use the dual monitor option on windows. also, just for fun is it possible to split an image between many different sources? It would be cool to have a bunch of old televisions stacked side by side and on top of each other, like a wall, all different, but still combining to create one image.
