# One Image/Vid on more than one screen

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.

Another piece of software that allows previewing the program material is Freepath from Grass Roots Software http://www.freepath.com/. The price is \$149.00. I have used a matrix switch with driver amps for choosing a single or multiple program sources on a single or multiple displays in a VGA environment. Thee product I used was for a classsroom situation where there is a desktop computer that the instructor may use but often they prefer to bring in their laptop to use instead. I needed a selector switch to chose the source computer and then a splitter amplifier to driuve the desktop monitor and the video projector located on the ceiling. I selected a 2 X 2 matrix switch made by StarTech which allows you to chose which source goes to each of the display devices. This is the model http://www.startech.com/Product/ItemDetail.aspx?productid=ST222MX&c=US and I believe that I purchased them for somewhat less than the price listed here. The switching is done electronically (which avoids the intermittent operation that the mechanical switches all displayed with some use) and is controlled by a simple pushbutton for each output that steps through source one, source two and no signal while showing the source chosen by LEDs. This approach would let you display the same signal on two screens and very simply switch between two sources for each display.

The key point needed if I read the request correctly is to be able to take a single image, and spread it across two displays. AFAIK freepath will not do this. It is great for a preview of a presentation, and using a DA for putting the same image on multiple displays but not for the "video wall effect"

yes, but a 70 dollar video card will do it.

What I am trying to do is project images on a cyc with cheap projectors, Using one image/video to be displayed on the cyc with two projectors carefully aligned and keystoned.

Will a program such as powerpoint or the open office version of powerpoint spread across the two screens, or can I only asign the slideshow to one output?

Also, any cheap slideshow/presentation programs that work well with video?
