Wireless iPad, iPhone, & MacBook AirPlay Mirroring to Projector

January 31st, 2013 No comments

As a professional educator and public speaker I am always looking for ways to make my presentations better. In addition to presenting clinics and workshops in hotel meeting rooms, I teach mobile web development and iOS application development classes and there are many times when I want to present information directly from an iPad or iPhone by mirroring the exact image on the device’s display. For my soccer referee clinics and workshops, I like to display scenarios using a variety of soccer field diagram iPad apps.

Ever since the iPad 2 and iPhone 4S I’ve been able to mirror the display using Apple’s iPad Dock Connector to VGA Adapter (works with iPhone too) and a standard VGA cable to the projector. This works just fine, however, I’ve found myself tethered to a desk/podium controlling the device instead of moving around the classroom. I’ve been looking for a way to make this work wirelessly and am happy to report that I have found success. The solution isn’t necessarily cheap, but it works great.

In addition to the projector and VGA cable, here’s what you’ll need:

The Apple TV device (2nd or 3rd generation) allows you to use Apple’s AirPlay Mirroring to show your iPhone 4S (or later), iPad 2 (or later), or MacBook screen on an HDTV using HDMI. In order for this to work properly, your Apple TV will need to be connected to the same WiFi network as the device you wish to project. See http://support.apple.com/kb/HT5209 for configuration details. Please note: this could present a challenge if you are using a public WiFi network that requires a web browser based confirmation screen because the Apple TV device doesn’t support that (yet). It does, however, support secure WiFi connections as long as the SSID and password are known to you.

If your projector is newer and has an HDMI port, the Apple TV device (2nd or 3rd generation) should be all you need. Most projectors in use today, however, do not yet support HDMI. The Kanex ATV Pro converts the HDMI signal from the Apple TV to VGA so that you can wirelessly connect your Apple TV to your projector. Once your configuration is set, you’ll be able to mirror your iPad, iPhone, and MacBook image to your projector without being tethered by a cable.

The Kanex ATV Pro is listed on the kanexlive.com and the apple.com web sites for $59.95, but I bought mine for $20 less at Amazon.com for $39.95 in January 2013.

I also bought my Apple TV from Amazon.com for $94.99, which was $5.00 less than the $99.99 list price at the apple.com web site.
