Duet Display, a terrific app which turns an iOS device into an external display for the Mac, has been updated in the App Store with official support for the iPad Pro and major performance improvements on both iOS and OS X.
The best thing about the updated app is its ability to allocate one-third of the iPad Pro, iPad Air 2 or iPad mini 4' display for iOS apps, with the remaining two-thirds of the screen real estate dedicated to Mac apps.
Dual-screening using an iPad Pro and Duet Display comes with zero lag, developers claim. Crafted by ex-Apple engineers who worked on the iPad and iMac, Duet Display through its desktop helper app appears as an external display hooked up to your Mac or Windows PC via the USB port.
