More along the lines of with windows u can press Fn( Function Key) + CRT/LCD and view your desktop tru another monitor or projector.
Any Help there........

Sure it is.

If your monitor is working already, and you just wanna start a specific application on the other one,

DISPLAY=:0.1 some_command

would launch it on DISPLAY 0.1

If you don't have your xorg.conf configured you have different options to do so.

For example this is my Serverlayout, I got my TV attached to my Laptop:

This creates a layout like this:



(==) ServerLayout "Layout0"
(**) |-->Screen "Screen0" (0)
(**) | |-->Monitor "Monitor0"
(**) | |-->Device "Videocard0"
(**) |-->Screen "Screen1" (1)
(**) | |-->Monitor "Monitor1"
(**) | |-->Device "Videocard1"
(**) |-->Input Device "Keyboard0"
(**) |-->Input Device "Mouse0"
(**) |-->Input Device "Synaptics Touchpad"
