Duet Display for iPad
A good second display is hard to come by, especially when you’ve been spoiled by a Retina display. But now you can put your iPad to use as one with Duet Display. Developed by ex-Apple engineers, Duet delivers lag-less full resolution at 60 frames per second by relying on the simplest physical connection — a single Lightning cable — which also acts to keep the tablet fully charged. The second display is also fully touch sensitive and works with all iPads running iOS 7 and above, all Macs on OS X 10.9 and up, and even on iPhones.
