how do you make a slide presentation to be viewed on TV?
how do you make a slide presentation in keynote on a disk so it can be viewed on a TV?
Two options:
The simplest way to do this if you have a "Smart TV" (the TV will have a USB connector) is to export the Keynote as an H264 file, Share > Export > QuickTime then copy this to a USB memory card plug it in to
the TV and play.
If the TV doesn't have USB, export a QuickTime video and create a DVD disc using a DVD video application; Toast, iDVD, DVD Studio pro.
