Many are not aware that in PowerPoint 2003 (and 2002/XP) there is a feature available called Presenter View, which allows you to use your computer's multi-monitor capability to better control your presentations.

In order to use presenter view, your computer must meet the following requirements:

• The computer must have multiple monitor capability - check with the manufacturer about this if you're not sure. Usually desktop computers require two video cards in order to have multiple monitor capability; laptops often have the capability built in.
• The computer must be running an operating system that supports multiple displays, such as Windows 98, Windows 2000, or Windows XP (or later).
• Multiple monitor support must be enabled by setting the display options. In Control Panel, click the Display icon.
• Presenter view must be turned on in PowerPoint.

Basically you just set up your second monitor in the display settings and check the "Extend my Windows desktop onto this monitor" box. Then in PowerPoint, follow the menus to set up the slide show (Slide show... Set up show...), and in the multiple monitors section, choose the extended monitor (your projector output) as the device on which to place the slides, then check the box to indicate you want to use the presenter view.

There you have it: One monitor with your notes and controls, and the other for your audience with just the slides. Cool stuff.
