I currently use a laptop and Keynote to present slideshows to my students. I make heavy use of the presenter notes feature to see previews of my next slide, leave notes to remind myself of what to say, and keep cleaner slides on the projector. I accomplish this via setting up the laptop as the secondary display and the projector as the main display.
I have the Splashtop remote desktop app for my iPad and successfully used it to control Keynote. However, it displays the primary display (slides) rather than the secondary display (presenter notes). Does anyone know if there is a way to have Splashtop pull the feed from the secondary display rather than the main one? I don't know if this is a simple setting I'm missing or if it's not possible.
