Avatron – developers of Air Display – a popular iOS app that allows users to use their iPad, iPhone and iPod touch as a wireless display for their Mac or Windows computer have just announced that they will releasing a new version of their app that includes support for the new iPad’s Retina Display.

After some initial hiccups, Avatron has managed to get their app working  on the new iPad with good performance. They have also added support for Lion’s hidden HiDPI mode, that renders with double-resolution on a double-resolution screen. MacRumors explains:

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 1024×768 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 “1024×768 (HiDPI)” mode in their System Preferences to take advantage of the new mode. 
Here’s how it looks like:

The goods news for other iOS device users (especially iPad 2 and iPhone 4S) is that, thanks to the performance  tuning and profiling, updated iOS app delivers dramatically better frame rates on their iOS devices as well.

Air Display is available in the App Store for $9.99 [direct App Store link] and the update with support for iPad 3’s Retina Display will be available as a free update.
