PDFPresenter allows to display presentations in PDF format on the external video adapter. It opens PDF presentations received via Mail, downloaded in Safari, or stored in any other application on your iPad. They can also be transferred from your Mac or PC via iTunes file sharing.
PDFPresenter also includes a presenters clock. It automatically connects to the display at the best available resolution, but if the screen or projects has problems with the signal, PDFPresenter offers full control over the resolution.
A unique feature is the built-in laser pointer. While you cannot usefully point a laser pointer at a large plasma display as some companies now deploy in meeting rooms instead of beamers, when using PDFPresenter, you can just touch the main view on your iPad, and a red dot will appear. You can touch with several fingers at the same time, red dots will show up for each finger, a multi-touch laser pointer.
