Alright, you've decided you want duet! That's great news. Here is a step by step tutorial of how to get started along with help to fix any issues you may have along the way.
You need two software applications to make duet work.
First, install duet for iOS. The latest version can be found here:
The app requires iOS 10.0 or later. 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 for Mac
The latest Mac version can be downloaded from duetdisplay.com/mac and requires macOS 10.9 or later (Mavericks, Yosemite, El Capitan, Sierra, High Sierra*, and Mojave). For the best experience on Mojave we recommend that you upgrade to 10.14.2+.
Download for PC
The latest PC version can be downloaded from duetdisplay.com/pc and requires Windows 8.1 or later.
Install on Mac
Double click the app. The app will move to /Applications and ask for your permission to add a graphics driver. The driver is required to render the high performance display on your iPad and we are certified by Apple to load the driver onto your Mac. As mentioned this installation will only add an additional driver for Duet's operation and will not affect your current system drivers.
Once the driver and app is installed, you will have to restart your Mac.
You've restarted, everything is installed and you're ready to go. You should see duet's icon, a circle with a lowercase d, running in the menu bar. You can access duet settings by clicking on this icon and then the settings gear inside the status window.
Install on PC
Double click the exe to open the installer and follow the instructions. You will need to restart your PC to complete the installation.
You've restarted, everything is installed and you're ready to go. You should see duet's icon, a circle with a lowercase d, running in the system tray of your PC. You can access duet settings by clicking on this icon and the status window will appear.
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/PC to Launching Duet right before your new desktop is displayed on the computer.
You now have more space to help you multi-task on your computer.
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.
Mac Display Settings
If you want to adjust the location of your duet display relative to the Mac then simply go to Duet's Mac app settings and click the shortcut Display Arrangement. This will take you directly to System Preferences > Displays > Arrangement. Here you can click and drag to move the screens to the layout you desire.
PC Display Settings
If you want to adjust the location or resolutions of Duet on your PC then click the icon in your system tray to open the settings. This will also link you to the PC's Display Settings to adjust monitor arrangement and other display options.
