Display 1 desktop or movie on many different screens.

Afternoon experts.

I am trying find out what the name of a device that will lets you display 1 computers desktop or application on many different video screens.

A perfect example is when you go into a computer store and they will have all their computer monitors displaying the same movie all from a single computer.

The general idea is I need to find out what this piece of hardware is, and any brands that I can search for online. Its basically just a video hub.

That's called a video distribution amp.  For example, Kramer makes the Vp-400 for 4 displays: http://www.markertek.com/SearchProduct.asp?item=VP%2D300N&off=0&sort=prod.  When you split the video, you need to boost the signal so that the voltage doesn't drop over a parallel circuit.
