Air Display works well, when it works

Last February I posted a brief review of Air Display, an iOS app that lets you use your iPad (or iPhone/iPod touch) as a second monitor. At the time, I had tested the app for only a short time and had done no real work using it.

For the past few days, I've been working from a hotel room in Denver and now have hours of experience using Air Display to turn my iPad into a second monitor for my 13" MacBook Pro. Or should I say, "attempting" to turn my iPad into a second monitor?

When it works, Air Display is a quite effective helper app, and increases my screen real estate by more than 50%. I use it in the following ways:

  • Menus - Adobe CS5 applications are infamous for their extensive menus which can consume your workspace and leave little room for the actual task at hand. Using Air Display, I can shift Photoshop's or Dreamweaver's menus onto my iPad and free up my entire MacBook display for the work.

  • Secondary applications - At any given time I'll have around a dozen applications open. Only a few of them are essential for the work I'm doing and I'll keep them on the notebook's screen. The others can be shifted to the iPad.

  • Separate browser tabs - Using Chrome's tear-off tab feature, I can move a browser window to the iPad while keeping the active window open on the MacBook. That's what I'm doing right now, in fact, with a separate tab on the iPad open to my previous blog post, while typing this on the notebook.
This is all wonderful in theory, but Air Display has some quirks that will drive you to distraction until you figure out how to work around them.

The initial connection process seems to be iffy. Since it requires that the Air Display apps be running on both your computer and your iOS device, if either of them aren't cooperating, you don't get a connection. I've found that after waking up my notebook and iPad in the morning, I need to quit the iPad app, and restart it - sometime a couple of times - before a connection can be made. Also, occasionally the iPad's screen will be blank (it should show your computer's wallpaper). For a while, I thought that indicated that the connection had not been made, but I discovered that dragging an application's window or a browser tab over to the iPad will, in effect, bring Air Display to life.

I also found that I had to disable my notebook's firewall in order to have a reliable connection with Air Display. I don't know if that's a quirk that's associated with the hotel's WiFi system; I didn't have that issue when I tested it at home. But if you're on the road and having problems, you might try this, assuming you're willing to live with the security implications.

And, finally, I've noticed that the longer Air Display is running and active, the slower it gets. This behavior is manifested by an increasingly jerky cursor movement, a disappearing cursor, or one that doesn't move at all. When this happens, a rebooting of the iPad and a reconnection of the Air Display software is often required to restore the original operation.

While these are not insignificant quirks, I must admit that Air Display has become an essential part of my "road warrior" toolbox. I'm willing to live with its eccentricities because when the app is working as it should, it makes a tremendous difference in my efficiency.
