Apple’s Digital AV Adapter provides video output from your iPad 2 in 1080p—although movies still play at 720p. But it works with any app, mirroring the display to your TV, projector, or other HDMI device. (Bring your own HDMI cable, of course.) It’s even got a 30-pin dock port so you can charge or sync your iPad while it’s connected to the TV. Bonus: it works with the first iPad (running iOS 4.3), the iPhone 4, and the fourth-gen iPod touch, although those devices all top out at 720p output. It delivers audio too! With this $39 dongle, you can “sneakernet” videos from your Mac to your TV via the iPad, instead of needing a $99 Apple TV. Smart.
