We had to do that for a trade show and cheated. We took many netbooks and had one per display. REMEMBER we had 5 days to get this working so no time to be fancy.
Each machine driving the display was easy. Now we installed all on a LAN and installed a small in house written app that would read a command file and then do what was in that.
So 5 days, 2 fair to good programmers and we went to the show.

Hi!
I am trying to find some software that could control 5 monitors independently at once, so that I can use it for multimedia presentation at my church. I now some people that use a program called "Media Shout," but as far as I know, it only allows dual monitor support. I am really looking for something that will support at least 5 individual monitors in such a way that they could display different things to each monitor and control each monitor's display independently. Does anyone have any idea what software I could use to do this? Thanks!
