If you’re looking to become more productive on your computer, a second monitor may be the answer. By adding a second display you may be able to get more done, boosting your efficiency and reducing the time you need to complete tasks.
Second monitors can be expensive, can consume a lot of space and aren’t mobile. But if you use your iPad as a second monitor, you can utilize tech you already own, use minimal desktop space plus have it with you on the go.
The Duet Display app, developed by former Apple engineers, allows you to use your iPad as a second monitor for your Mac computer. This handy app not only saves you money by not having to purchase a second monitor, it works smoothly so you don’t have to worry about lagging or stuttering on your computer or your iPad.
This video demonstrates Duet Display in action:
Getting Started with the Duet Display App
Using this app is about as simple, smooth and intuitive as an app can be. To use the Duet Display app you must get the app for both your Mac computer and your iPad.
- Get the Duet Display app for Mac at the Duet website.
- Then get the Duet Display app for iPad/iPhone.
The good news is that the Duet Display app is free for your Mac. The bad news is that the app currently costs $15.99 for your iPad. $15.99 is very expensive for an app, but very inexpensive for a second monitor!
Installing Duet Display on Your Mac
When Duet Display is installed, you will see the Duet icon in the top menu bar of your Mac. →
Click on that icon to get information about the app and adjust the settings.
Installing Duet Display on your iPad
Download the Duet Display app and open it. You’ll see instructions to get started:
Tap Got It and connect your iPad to your Mac with either your lightning or 30-pin cable, depending on which model iPad you own.
Using the Duet Display App to Turn Your iPad into a Second Monitor
After you have the Duet Display app open and your iPad connected with a cable to your Mac, you’ll see a flicker on your Mac screen and then your display will appear on your iPad. You can use your mouse or touchpad to move a window from your Mac onto your iPad. Drag the window to the right side of the screen of your Mac and watch it appear on your iPad.
Controlling the iPad
Because your iPad is now a second monitor, the controls are different than if you were using a regular iPad app.
You can control the window that is open on your iPad with the keyboard and cursor from your computer. Move your cursor over to the iPad screen by moving it past the right side of your computer screen and you will see the cursor appear on the iPad screen. Click on the iPad screen to be able to use the keyboard on that screen.
The touch screen of the iPad will work in a limited way within the Duet Display app. Tap with one finger to click as you with the left mouse button. Tap with two fingers to right-click. The iPad keyboard does not work in the Duet Display app, you must use your Mac keyboard.
You can watch videos on your iPad as a second monitor within the Duet Display app. Sound will play out of the Mac speakers.
Duet Display uses a cord to link your iPad to your Mac. Those who aren’t fans of cords may wonder why Duet doesn’t use Bluetooth or Wi-Fi to connect the devices.
By using a corded connection Duet is more stable and smooth, you don’t have to wait for the connection or worry about it dropping. The cord also supplies some power to your iPad, prolonging its charge. Further, the corded cable is more secure, you don’t have to worry about hackers trying to get into your Mac wirelessly by using the Duet Display app.
