SplitShow

A tool for the dual-head presentation of PDF slides on Mac OS X, most likely using a laptop and a projector. The project arose out of the need to correctly project slides created with LaTeX’s beamer class.

This project has been imported from the original, discotinued Google Code project (http://splitshow.googlecode.com).
The aim is to create an up-to-date version of the SplitShow program with the same features and to extend it later on.

Dual-Head Full Screen Mode at Native Resolutions

Traditional PDF viewers require two displays to be in “mirror” mode in order to show the same image on both. The – maybe not so obvious – disadvantage of this is that the higher-resolution display is forced to used the resolution of the lower-resolution one. By keeping the two displays at their respective native resolutions in “extended desktop” mode, your slides will always look great on either side.

Installing SplitShow

To install the pre-build app rather than needing to compile this application, visit the Releases page and download SplitShow.app.zip from the latest release (you may need the alpha release for new macOS platforms). Extract the zip file and use the SplitShow.app executable.

(you may need to tell GateKeeper to allow the app to run by going to System Preferences -> Security and Privacy since it isn’t signed with an Apple Developer ID)
