Hack You iPad to get Wireless HD Video Mirroring
“Teachers and corporate presenters alike begged Apple for video mirroring capabilities for the iPad, and the company delivered the feature in the iPad 2. Apple’s solution still leaves users tied to a cord, however, so two employees at networking service provider Straight Up Technologies developed a simple hack to give their client wireless HDMI output and freedom of movement while sharing the iPad’s screen.
The iPad 2 can mirror its display in 1080p HDMI video over the new Digital AV Adapter, which plugs into a Dock connector and has an HDMI port on the other side. For some presenters, being chained to a cable isn’t much of an issue, but teachers in particular have told Ars that one important advantage of using iPads in the classroom over laptops is the ability to walk around the classroom and interact more directly with all the students in the room.”
