Multiple Monitors, one PC

I have a computer and a bunch of monitors connected to it via networking cables. I want to be able to have ALL monitors show the same thing but from one central computer. Thanks! i am brand new to coding in lua.

Easiest way would be to use this porgram: http://www.computercraft.info/forums2/index.php?/topic/15873-mirror-utility-program-contents-of-computer-screen-on-monitor-v2/

If you want to have this build into your program I would look at the above link and study how that program works when interacting with monitors.
