Alright, you've decided you want Duet – that's great news! Here's a step-by-step tutorial of how to get started along with help to fix any issues you may come across along the way.
You need two software applications to make duet work – one in your computer and another in your iDevice.
Download and install for iOS
First, install Duet for iOS – the latest version can be found here. The app requires iOS 12.0 or later – although, previous app versions are compatible with iOS 7.
Installation is simple, like any other iOS app, just download and you'll see the icon on your home screen. Tap on it to open when you want to use Duet.
Next, you need Duet for Mac or PC. We distribute the desktop apps on our website and they are free!
Download and install for Mac
Download the latest macOS version from here – requires macOS Mojave 10.14.2 or later. The product does work on 10.12 and 10.13, but we do not officially support those versions if any issues are encountered.
To install the app, please double-click on the .app file, which will install Duet in your Applications folder. Once installed, you will see the app's icon in the menu at the top right of your Mac (a lower case d with a circle around it). If you need to change any settings, click on the menu bar icon to open Duet's UI on macOS.
Download and install for Windows
Download the latest Windows version from here – requires Windows 10 or later.
To install the app, please double-click on the .exe file, which will install Duet on your PC. Once installed, you will see the app's icon in the menu at the bottom right of your PC (a lower case d with a circle around it). If you need to change any settings, click on the menu bar icon to open Duet's UI on Windows.
This is the easy part. Start Duet on iOS and on your Mac or PC. Now connect your iPad or iPhone to your computer using either USB to 30 pin, lightning cable, USB-C and/or USB-C to USB-C (the same one you use for charging) and voilà!
When Duet detects the iPad or iPhone it will change the message from "Connect to Mac or PC" to "Launching Duet" right before your new desktop is displayed on the computer.
You should now have a second display connected to your desktop! Just click and drag the title bar of your apps and move them across the edge of your computer's screen to your new Duet Display.
