Dual view can help you deliver your PowerPoint presentations professionally, without the need to turn away from your audience to read a overhead screen, or the aid of written notes. Dual view allows PowerPoint presenters to show slides on a second monitor and view the same presentation on their computer. A computer's hardware system must support dual monitors to enter dual view mode (see PPTools Reference). Luckily, Windows 98 and higher supports dual monitors. Ditch those note cards, and face your audience during your PowerPoint presentations using dual view.
Connect the second monitor to your laptop's VGA port.
Open the "Start" menu and selecting "Control Panel". Double-click the "Display" icon.
Go to the "Settings" tab and press "Identify" to make sure "Monitor 1" represents your laptop and "Monitor 2" represents the second screen.
Check the "Extend my Windows desktop onto this monitor" check box and press "OK". Now you should see your laptop's desktop on the second monitor.
Open PowerPoint, proceed to the "Slide Show" menu, and open the "Set Up Show" dialogue box to configure PowerPoint to display on both screens.
Open the "Display slide show on" drop down menu in the "Multiple Monitors" menu and select "Secondary Monitor" option.
Open your slide presentation and play it in PowerPoint's "Normal" viewing mode, so the presentation remains in sync on your laptop and secondary screen (see Microsoft Reference).
If your desktop does not copy onto the second screen in step four, restart your computer and repeat the process again (see Microsoft Reference). If problem persists, press the "Advanced" button on the "Settings" tab. Click the "Graphics Media Accelerating Driver tab" and select the "Graphics Properties" button. Click the setting for "Extended Desktop" and set our primary device to "Notebook" and secondary device to "Monitor".
