Turn Your iPad Into an Extra Display
You would like to work more productively and are used to work with an additional screen? Duet is an app designed to let you get some extra use out of your iPad instead of using an conventional display.
The developers of Duet recently introduced an app that allows you to use your Apple device via a Lightning- or 30-pin cable as an extra monitor for your Mac.
The app was developed by former Apple engineers and enables connections with up to 60 frames per second and therefore no delay. Thus, it will now be possible to flexibly work on the go with two monitors.
