When giving a PowerPoint presentation, you may want to be able to see your speaker notes on screen though you don’t want them visible to the audience. This is possible if you have two monitors available to you.
In Microsoft PowerPoint 2007 or Microsoft PowerPoint 2010:
Open the PowerPoint presentation. On the Slide Show tab, in the Monitors group, click Use Presenter View.
The Display Properties dialog box opens. If the Use this device as the primary monitor box has a tick in it and it is greyed out, then the monitor is the primary monitor. To use a different monitor as the primary monitor, click on its icon and tick the Use this device as the primary monitor box. Click the monitor icon for the audience’s monitor, and then select the Extend my Windows desktop onto this monitor check box. Click OK.
On the Slide Show tab, in the Set Up group, click Set Up Slide Show. The Set Up Show dialog box opens.
In the Multiple monitors section, select the required options, then click OK.
You can now see the slides with speaker notes on one screen and the slide show itself on the other.
