Developer Avatron announced its “Air Display” app, which allows iPhones, iPads and Macs to act as a second or third monitor, would be implementing support for the 2048-by-1536 resolution of the new iPad’s 264-DPI Retina display. That means you will soon be able to use your third-generation iPad as a 2048-by-1536 computer monitor.
The update will also benefit the iPad 2 and iPhone 4S with “dramatically better frame rates.” In addition, the upcoming update will allow you to enable HiDPI mode in Lion or Mountain Lion, a “feature in Mac OS X that renders with double-resolution on a double-resolution screen.” The results of turning on HiDPI mode in OS X is viewable in the image to the right. Avatron explained on its blog:
The best 4K & 5K displays for Mac
To turn on HiDPI, you just go to the Displays Preferences and select 1024×768 (HiDPI)… HiDPI has been shipping with Mac OS X for some time. But it isn’t enabled in the System Preferences, because until now there hasn’t been a mass-produced computer display with high enough resolution to do it justice. That’s where Air Display and the new iPad come in.
Avatron noted it is waiting for “another Apple review cycle” before the update goes live on the App Store. We will keep you updated when it does.
