This is a pic I found on the internet. I am currently running a crt and lcd together at work. Just like the photo, one monitor contains the start bar while the other just acts as a "spill over" screen. You can drag a window size to make a window take up both screens. However, when you full size a window, it will only fully take up 1 screen, depending on which screen it's mostly in. For mine, I like to have a second set of shortcuts on the other monitor, to avoid having to move the mouse all the way over to one screen each time, as in the example. Overall, I REALLY
like dual monitors. If you have the means, and the desktop space, it is really worth it.
