I just got my iPad Friday. One of the first things I tried was Keynote because I hope to use that for an upcoming presentation. After creating a few slides, I wanted to see how it would work on a monitor. So I hooked up the via adaptor and got - nothing. Nothing on the monitor at all. Am I missing something? Is there something have to do in Settings or in Keynote to tell it to use the monitor? I thought if I just hit the play arrow it would go there?
