'Air Display' to Let You Use the New iPad as a HiDPI 'Retina' Display for Your Mac

Avatron, the makers of the popular Air Display app for iOS, revealed today that they will be updating their utility to fully support the 3rd Generation iPad.

Air Display allows you to use your iPad (or iPhone/iPod Touch) as an extra display for your Mac or Windows computer. This old video shows how the app works.


The iPad acts as a wireless second screen that can be used by OS X in the same manner as any other monitor.

The developers were able to get their screen-extending app working with the new iPad with good performance. But using a 2048x1536 iPad as a secondary screen computer screen would result in very small windows, text and user interface elements. So, the team has also included support for Lion's new HiDPI mode. We've covered HiDPI mode in the past. HiDPI mode allows OS X to support high resolution monitors while retaining the same relative size for user interface elements, such as windows and buttons.


HiDPI mode will let the new iPad act like a 1024x768 point screen where each point is made up of 4 pixels. Apple has already built in support for HiDPI and some of their Apps, such as Messages, already include Retina-sized artwork that work in this mode. Users simply have to choose "1024x768 (HiDPI)" mode in their System Preferences to take advantage of the new mode.

Air Display is a $9.99 Universal App in the App Store. [iTunes] The Retina-enabled version will be included in a forthcoming update.

I have Air Display, but my stupid ass didn't read the description fully and I didn't realize that my Macbook Pro isn't compatible with it. BLAH!

I just wish they could increase the refresh rate and reduce the noticeable lag that the app has.

I would use it a lot more if it wasn't so laggy.
Will pushing more pixels to it over the air result in further lag ?

Would work pretty good for Photoshop palettes, I wish you could select things on the iPad's screen using your finger instead of the cursor however.


You can use your finger...that's what she said :p

This is one of those apps that need to be free and have an in app purchase to activate it.

It could have a huge flashing watermark in the middle of the screen, but at least you'd know if it worked or not. If you minded the refresh rate or not.

Then, they'd probably only get good feedback.

I'd try it if it was free, but otherwise $10 for something I might not be happy with?

(And if it used USB, wouldn't that be faster than WiFi and it would charge your device at the same time?)

Anyone know if this will let the iPad act as a 3rd monitor? That'd be great for having books / manuals / email app open while I am working.

Now that's an app I would consider paying for. Still hate the idea of paying for something I'll probably never use, but this has some real utility to it. :p

How easy/difficult is this to set up? I see that it supports Windows as well, which is cool... although Aero and DirectX will be temporarily disabled while the app is connected... :(


I set it up in less than five minutes -- including installing the iOS app, installing the Mac app, and rebooting my MBP. When you're in the app on the iPad and the AirDisplay "server" is turned on on your Mac, your Mac recognizes the iPad as an external monitor and treats it as such.

I now have two external monitors -- one on either side of my MBP. One is a 22" and the other is a 9.7" iPad. The touch screen interface on the iPad has proven to be effective with e-mail reading/archiving when I'm at my desk; and it's nice because I can keep e-mail off my other screens and save that screen real estate.
