Does anyone know if you can stream your iPad or iPhone screen to the tv. I need to see all actions that take place not just certain apps like the cable only allows.
AirPlay only streams certain video content. It sounds like the OP wants to do a mirror of the entire screen.
There's obviously some way to do this since this is what Steve Jobs does at every keynote, though I've heard that the iPad he uses might have special hardware to enable it. It's not possible with regular software, but it might be possible with a jailbroken iPad.
One possible point in having it on a TV screen is for presentations. Just like you can with computers.
With iPads being used in many facets of the business environs, I can easily see a need to be able to present what is on the iPads screen onto a television or projected image.
