We strongly recommend using a touchscreen monitor for customer display; however, utilizing a tablet as a secondary monitor is also permissible. Please be aware that certain vendors might enforce restrictions based on the operating systems used, so compatibility should be considered.
If so, you need to install a second monitor app on your Android or IOS device and install the app’s drivers on your computer. Once done you can connect your Android or IOS device to your computer, using a USB cable or WiFi (when both the devices are connected to the same network) and that’s it. You don’t need an Internet connection. So, let’s begin.
In this example, we’re using Duet Display, which was developed by a team of ex-Apple engineers. Duet Display allows you to use the tablet as a second display not just on your Mac, but a PC too.
Duet Display also provides limited touchscreen support, allowing you to tap and swipe your way around Mac OS. It means you don’t have to spend your time moving your mouse between the two screens, which becomes especially laborious when using a trackpad and again, enables users to be more productive.
We’ll show you how to set up Duet display to use your iPad Pro (or any other iPad or iPhone) as a second display for your Mac or PC.
Here’s an overview of how to use your iPad Pro as a second display using Duet Display, with more in-depth instructions below:
- On your iPad Pro, open the App Store and install Duet Display – at the time of writing, it costs £19.99. It’s a universal app, so it’ll also be available for use with your iPhone.
- On your Mac or PC, head over to the Duet Display website and download the Duet for Mac/Windows app.
- Install the Duet companion app for Mac or PC. This is an important step, as the companion app allows your iPad and Mac to ‘talk’ to each other. Follow the installation instructions, and restart your Mac to complete the installation.
- On your iPad Pro, open the Duet Display app and plug it into your Mac or PC using a Lightning cable (or 30-pin cable if you’re using an older iPad).
- The iPad Pro should be recognised by the Duet companion app, and your desktop should now extend across the two displays. You’re then ready to go! Quality settings can be tweaked via the Duet companion app on your Mac or PC to provide higher graphics, smoother refresh rates, etc. and to disconnect the display, simply close the app on your iPad.
Spacedesk
Spacedesk is the app to use if you want to extend or duplicate your computer desktop to another device, from another computer to a smartphone. The beta version is FREE to download now. Whether you need to expand your desktop or duplicate what you see there, Spacedesk has a solution for you.
Spacedesk needs – it makes sense – at least two devices: the primary machine and the secondary machine, which must be connected to a LAN (Local Area Network). The Network protocol TCP/IP needs to be supported, but once that happens the connection can be over USB (e.g. tethering), via LAN-cable or wireless.
