First Look: Avatron Air Display for iPad extends your Mac screen

Avatron Software already has an iPad hit on their hands with AirSharing (US$2.99, $9.99 for Pro edition). Now they're on the verge of releasing a new and useful app that could change the way that you use your iPad and Mac together. We've got an exclusive pre-release look at this intriguing app, called Air Display.

The concept behind Air Display is cool -- use your iPad as a small extension to your Mac's display. For example, let's say that you're working on a project and you want to use your entire screen, but you'd also like to be able to check your email in You fire up Air Display on your iPad, move the Mail window to your iPad, and now you have a small portable workspace that's not interrupting what you're doing on your Mac.

Apps like this are nothing new; just before iPad launch day, Shape Services released iDisplay ($4.99) which does the same thing. However, reviews of that app have been poor and it's pricey for what it does. Our very own Erica Sadun noted another solution in a post about a week later. Her post mentioned ScreenRecycler ($29.90), which uses a second computer (Windows, Mac, etc...) as an additional monitor for your Mac.

The iPad and Mac need to be on the same Wi-Fi network for Air Display to work, naturally. The app and companion System Preference on the Mac (below) work so well together that I had no issues watching YouTube videos that were playing on the Mac on my little "side screen." They looked great on the iPad, although it was disconcerting to hear the sound coming out of the Mac.

One really great feature of Air Display is that not only is it an additional screen for your Mac, but it also adds a second input device to your Mac. I was able to use my finger on the iPad to call up incoming email that was appearing on my virtual screen. I didn't find the accuracy of finger input to be very good in this pre-release version, though, and ended up resorting to a Pogo Stylus for better input accuracy.

There were a few bugs in Air Display, which isn't surprising considering that it's still in beta. When I first started streaming a virtual Mac screen to my iPad, I noticed that the connection kept dropping. A look at the AirPort status in the iPad status bar indicated that the Wi-Fi signal strength had dropped to about one bar, much less than the five bars I see on my network. I rebooted the iPad and everything worked fine after that.

There were also some interesting screen artifacts that sometimes showed up while using Air Display. Once again, they didn't keep me from using the second display, but they just looked a bit odd. Avatron spokesman Elliot Chase mentioned that the artifacting issue and dropped connection issues have been resolved in preparation for release.

Dean Beeler, of Zinger-Soft, who has been working on Air Display at Avatron, noted that after three months of development Avatron is pretty comfortable with how the app is working right now. He mentioned that he's "really proud of it,", that "it keeps pace with playing YouTube-sized videos just fine," and "the only pain points for screen updates are full window moves" that they're working on.

Avatron hopes to submit Air Display to Apple for approval next week, with an expected price of US$9.99.
