 When the presentation program displays the specially prepared superwide \beamer-presentation, exactly the left half of the screen will be filled with the main presentation, the right part is filled with the auxiliary material---voil\`a. Not all presentation programs support this special feature. For example, the Acrobat Reader 6.0.2 will only use one screen in fullscreen mode on MacOS~X. On the other hand, a program named PDF Presenter supports showing dual-screen presentations. Generally, you will have to find out for yourself whether your display program and system support showing superwide presentations stretching over two screens.

+\beamer\ uses the package |pgfpages| to typeset two-screen presentations. One can choose from several appropriate options for showing something special on the second screen. These options are discussed in the following sections.
 
 One of the things these options do is to setup a certain |pgfpages|-layout that is appropriate for two-screen presentations. However, you can still change the |pgfpages|-layout arbitrarily, afterwards. For example, you might wish to enlarge the virtual pages. For details, see the documentation of |pgfpages|.
