Kanex ATV PRO Adapter for Apple TV
The Apple TV is a very useful tool for classrooms and conference rooms. By using AirPlay, you can easily display presentations, spreadsheets, or other information from a Mac or iOS device. Most modern projectors have HDMI inputs, but many older ones do not. The Kanex ATV Pro adaptor allows you to plug an Apple TV up to a projector that only has a VGA port.
