iOS devices are easy to use as a second screen for their Mac. You can find out how to do this here.
You travel with Macbook and iPad and would like to use your tablet as a screen extension? Or you have an old iPad at home, to which you want to give a new task? No problem. Different companies offer solutions on how to easily connect their iPad to their Mac and use it as a second monitor. This is possible with special accessories, or simply by app. We show you how it works. Best of all, it all works on the iPhone.
Duet Display is a paid app developed by former Apple employees. The principle is simple: you install an app on your iPad and on your Mac. Then connect the two devices with one cable and voila: you have a second screen on which you can work. You can even continue to use the touch screen on the iPad. If your Mac does not have a touch bar, you can have one shown on your iPad. The price of the app is 22,00 Euro.
The interior in detail:
- Download the software on your Mac and iPad. The macOS software can be downloaded here for free. The iOS app is chargeable and available through the App Store.
- Start the installation on your Mac and follow the installation instructions. During the installation process, you will need to restart your Mac once. After the setup is completed, the program starts automatically. Whether the program is running is indicated by the Duet display symbol in the upper right bar.
- Download the app on your iPad.
- Connect your iPad to your Mac via direct cable connection.
- Launch the Duet display app on your iPad and follow the instructions on the screen. Make sure that the application is also running on your Mac.
- The devices connect automatically and your iPad turns into a second screen for your Mac. You can set it up and configure it in the system settings like a normal screen.
- Tip: Click on the Duel Display icon on your Mac to open a window. The gear and the advanced settings option allow you to configure the connection of the devices (eg frame rate and image quality)
Our impression of Duet Display
With their price of just over 20 euros, the solution convinces us. The app is easy to set up and runs pretty smoothly and reliably. That the touch function can continue to be used is a nice addition. However, macOS is not designed for touch operation. Although it works quite well in principle, it is often the more complicated way. In everyday life, we mostly used the mouse to operate the second monitor. The same applies to the fade-in touch bar. It’s great that the function is there, but we find most of the features of the Touch Bar on our Apple keyboard. On iPads, the Apple Pencil is also supported, but the feature works rather poorly than right. The developers offer additional paid supplements, also one for a more precise Apple Pencil support. Not a perfect solution.
- Fast setup
- Liquid operation
- Touch screen still usable
- Insertion of touch bar possible
- Apple Pencil is supported …
- … but it is not precise enough
- Basic version is chargeable but does not offer all features (Pro version needed)
- If screen mirrored: Poorer performance
