i just grabbed a software called MaxiVista. You can google it. Basically, it uses your network to access another computer, and you can use that other computers monitor as a second or third.
The one on the right is actually connected to my laptop. The one on the left however, is actually connected to a different computer entirely. Here is a little video I made for it:

Ultramon is cool bc not only does it allow you to move windows from screen to screen without dragging and dropping, it gives each monitor its own toolbar, so that whatever window is on the monitor, its also in the monitors toolbar, and not clogging up your main monitors toolbar.
Just thought some here might find this useful.
