Duet Display for Mac is a very useful mobile phone tool that can allow macOS users to transform their iPhone or iPad devices into a fully-functional second screen. By using Duet Display for macOS, you can easily extend your current workspace no matter if you are a desktop or laptop user, enhancing your ability to multitask and optimizing your workflow with more easily available data on screens around you. Additionally, this second screen can still retain touchscreen functionality, enabling you to be even more productive than with a regular non-touchscreen standalone Mac monitor.

With the app, you can delay or even cancel a purchase of standalone secondary monitors, and simply use the iDevices that you already own to increase your productivity and enable your home Mac or a laptop to extend their desktop surface beyond its regular main screen.

Installation and Use

It comes in a fairly large installation package that will require up to several minutes to install depending on the configuration of your home Mac or laptop. After successfully finishing the easy-to-follow installation procedure, you will be welcomed with a very simple app interface that consists of a single control screen and just a few on-screen configuration options. But to access those configurations you first need to properly set up your iPhone or iPad. First, download and start Duet Display mobile app, and connect the device with Mac using a USB cable. Wireless communication is not supported.

The app can be used to configure three aspects of the connection quality – Framerate (60fps is recommended for most fluid use, but that setting can tax computer resources and faster drain your laptop battery), Performance (which will impact the image quality, three presets are available -High Power, Energy Efficient and Pixel Perfect), and finally Resolution (with support for Retina resolutions of latest iPads and iPhones).

To best take advantage of your tool, make sure that your iPad or iPhone device can support higher resolutions and your Mac can handle the rendering capacity needed to send a higher quality image to the external display. To save on resources, you can always reduce quality settings and find the most optimal image quality presets that fit your needs. Be aware that if your Mac or Laptop gets burdened with additional processing during the use of DuetDisplay (such as converting video files in another format), image quality and connection stability of external display images may suffer.
