Awww man it really does look sweet!
Sorry if it seems i might be jacking your thread but i'm really hyped up to do this now that I know that you can do this!
I well want to go triple display setup now but they don't make my LG monitor anymore, if I've got it right though I can add any same size monitor that does the same resolution and has the same refresh rate for it to work??
I understand that contrasts and screen heights may differ though.
