I just purchased the VGA adapter for the iPad so I could use it to present some content. However it works in a slightly misleading manner.
Not all iPad screen output is automatically pushed out to the device when plugged in. For example I navigate through my video files in iTunes on the iPad (external screen blank) until I click Play. Then the video appears (and works flawlessly) on the external monitor. But the iPad screen freezes and shows a still frame.
Similarly with iPhoto. I can navigate through images and folders only on the iPad. My pictures only appear on the external monitor when I start a slide show.
So those two limits are perhaps manageable. But the killer was iBooks. I had a presentation to give but not having Keynote installed on the iPad I instead exported as a PDF and added to iTunes for viewing via iBooks. However there’s no VGA ‘output’ for any content in iBooks. So the external monitor remained frustratingly black.
So short of buying Keynote for the iPad, my only other option would be to export as a movie and watch through iTunes. How painful is that!
Here’s hoping there’s a configuration setting I missed…….
