Inspiration Presenter vs. Inspiration 10
Inspiration 10 includes a stand-alone application you can use to present your slideshow, called Inspiration Presenter.
Inspiration 10 and Inspiration Presenter both include all the functionality you need to show your presentation, including support for two displays.
If the computer used for presentations has Inspiration 10 installed, you can use that to show your presentation. Otherwise, Inspiration Presenter is free and is easy to install and remove.
