If you’ve ever felt a need of a secondary display, you’d have definitely come across Duet Display. It is the most popular app that lets you use your iPad as a second display for your MacBook. The app is on top of the list no doubt but comes for a price of $20. But would you wanna burn a hole in your pocket for this? We’ve always tried to offer some of the best yet, lesser known products that you can use as alternatives. And today, we are going to see some of the best Duet Display alternatives. Let’s begin.

I was beyond impressed and completely blown away by the quality of the The Apogee Duet for iPad and Mac. First of all, it is build solidly and the construction is second-to-none. The ease of use with the front display is remarkable, and the Maestro 2 software is wonderful to navigate. The sound of the The Apogee Duet for iPad and Mac is pristine. Apogee Duet sets the industry standard for portable professional audio recording on Mac, Windows, iPad and iPhone. Made for the musician, producer and engineer that wants the ultimate sound quality and elegant simplicity, Duet features legendary Apogee AD/DA conversion, 2 world-class microphone preamps, USB MIDI I/O and ESS Sabre32 DAC technology.

Some of the apps in the list are not an exact replacement of Duet Display, as they are more likely to mirror your computer display to iPad rather than using it as the second display. But nonetheless, they still do something out of the box, which is why they made into the list.

Duet Display Alternatives

1. Sidecar (upcoming)

In WWDC 2019, Apple announces, Sidecar. The perfect replacement to Duet display. Just like Duet Display, Apple’s Sidecar works directly with a wired connection or wirelessly via Bluetooth. Unlike Duet Display, there is no WiFi support, which means, it will only work within a range of few meters. Also, both iPad and Mac should be under the same iCloud account. Once connected, you can use your iPad as a mirrored desktop or secondary display. Of course, it also supports Apple Pencil.

However, most of you won’t be able to use this feature yet. You need to be running the latest software i.e. macOS 10.15 Catalina on your Mac and iPad OS on your iPad, both of them not yet released to the public. Although, you can try the public beta, which we did and unfortunately, the sidecar feature didn’t work for us as of yet. But Apple being Apple, once this feature rolls out officially, I’m sure it’s going to work flawlessly.

2. Easy Canvas: Draw on iPad for your computer

Artists all around the world have loved the idea of digitally drawing their ideas because with technology everything can be accentuated and becomes a little easier to follow through. Professional Graphic Tablets are pretty expensive on their own and it would be nice if we had a more viable option.

EasyCanvas is a mirroring app that lets you project your mac or windows computer on the iPad, pretty cool right? It is available as an app for the iPad and a software package for the computer. The computer applications are available for free and you can download it from the website.

How does it work?

EasyCanvas works as a digitizer and is very easy to install. You download the app from Apple app store on the iPad. Your computer requires a separate download which can be downloaded here. After you set up both the applications, its just plug and play. Open both the applications and connect your iPad using a USB cable and it immediately detects the device and starts projecting it to the iPad. Now the app offers a couple of different options which come in handy while you use software like Photoshop to draw. Apple Pencil (only on iPad Pro) and Wacom pen are supported by this app and you can use it to draw. It has an option to reject accidental palm touch which would come in handy.

Second Monitor: Easy Canvas only supports screen mirroring, however, they also have an app that works as an extended display too. It is called TwomonUSB and the only issue is it cost $11, with no free trial.

3. AstroPad: Digitize the iPad

Created to be a perfect tool for artists, AstroPad visualizes an artist’s vision in a digital environment using the iPad as a digital input device. iPad functions as a touch responsive screen on which you can draw on too.

Astropad is only available on Mac and works similar to EasyCanvas. It converts your iPad into a digitizer which is very useful if you work with creation tools. You get individual software for your mac and iPad, Astropad comes as a trial version with 7 days and they bill after your subscription expires.

How does it work?

To get started, install Astropad app on Mac and the iPad. You can choose the wired option and plug the USB in or connect Astropad wirelessly. The devices have to be on the same network or it won’t connect. It doesn’t take long to connect and is actually faster than most apps. It displays the screen on the iPad cropped to fit the screen but you can also adjust the size with the dedicated toolbar on the left which has a couple of different options.

Apple pencil strokes are specially configured and included with this app. The strokes are identified with the inbuilt processing system of the Apple Pencil. It sends the data to the iPad and the software recognizes the pressure, altitude, and azimuth for the most natural stroke generation.

4. Splashtop Wired Xdisplay: Extend your Display

I’ve personally used Splashtop for a long time and they’ve grown as a company and rolled out a few different software. Splashtop Wired Xdisplay is specially designed to convert your iPad or any mobile device for that matter into an extended screen of your computer.

How it works?

Splashtop Wired Xdisplay requires the installation of two separate software agents, one on the mobile device and the other on the computer. The desktop agent is a very simple app that works by creating a digital extended display on the desktop and then projecting it to the iPad. Rather than just projecting your extended display, you can also control the actions with the touchpad. There isn’t much left to do after that. You don’t get additional features like customized pencil strokes or palm rejection.

Duet For Ipad Mac

Second Monitor: Yes, it is just a tool to convert your iPad into a second Screen.

Availability: Splashtop Wired Xdisplay is available for Windows and Mac computers and works across all mobile device platforms including iOS, Windows, and Android. Check it out here:

5. Team Viewer: Free Alternative to Duet Display

Team Viewer is one of the biggest players when it comes to remote desktop services. It offers free services to consumers and a paid version for commercial use. It initially offered desktop to desktop remote access over the internet. Its services are highly dependent on the network speed and it works with an encrypted key to provide security. As the mobile devices became more powerful and fast, it only made sense that we had an option of using our mobile devices as hosts or guests to log in to remote devices. TeamViewer allows any device to access a device anywhere on the planet to be accessed, provided it has the TeamViewer Software installed and a working internet connection, preferably high speed.

How it works?

Downloading the software is easy and done through their website. After installation is complete, the app displays a unique ID which is unique worldwide and you can access it only with the password generated right below. When you type the Id and password and hit enter, the app takes over the screen and starts transmitting it over the internet to the device that has accessed it. You can control the mouse and keyboards of the remote device with your own input devices. TeamViewer translates all the input values and sends them over to the remote destination. this app has one additional feature which transmits the audio from the remote destination to your device. For example, if you were to play a youtube video through TeamViewer on the remote device the video will play with audio on your device as well, this feature isn’t available with the other apps.

Second Monitor: There is no option to use your iPad as a secondary display using a TeamViewer app, however, you can still control your Computer from your iPad.

Availability: TeamViewer is available across all platforms and can be downloaded here.

Download TeamViewer (Free)

6. AirDisplay: Wireless Duet Display Alternative

Duet Ipad Mac Mini

AirDisplay offers a wireless option to connect your iPad or an iPhone as an extended display with your computer. It works with mac and windows users wouldn’t have to settle for any of the above options.

How it works?

It has a similar operation to other packages listed, you begin by purchasing an app for your iPad or the iPhone and download the driver app on the mac to complete the setup. Now when everything is ready, the mac window displays the connected device as an icon. You just have to click connect and just like that, it makes it an extended display. The upside to this app is it uses Wi-Fi to connect the two devices and broadcasts in high speed. You can connect up to 4 devices to make it a display, which would help in increasing productivity.

Second Monitor: Yes

Availability: It is available for Mac as a host and clients can be Windows, Mac, or Android.

How it works

iDisplay claims 60fps video transmission on extended displays but that totally depends on your device’s capability and Wi-Fi capacity. If you’re broadcasting through it, make sure the devices are on the same network. iDisplay supports multi-touch across all platforms which is better than the other apps that did offer multi-touch didn’t. It has a feature known as smart screen resolution which essentially automatically adjust your extended device’s resolution automatically. You can connect more than one device with iDisplay.

Download iDisplay ($15)

Duet Display Alternatives: Final thoughts

To fuel our productivity, the apps listed in this list are versatile. EasyCanvas and AstroPad act as a mirror and a digitizer with a special apple pencil touch feature. It lets you make the best use of creation tools. If you’re looking for something more than just a digitizer, Splashtop takes the cake. It has options to make it an extended display too.

TeamViewer is free and works well wirelessly, it is best suited to mirror your computer. AirDisplay and iDisplay are paid but have distinct features like high-speed video transmission without latency wirelessly, and multi-touch across all platforms makes it a good choice for people looking for a more comprehensive app.

Duet Display For Ipad

Audio Interface For iOS

The Duet 2 was reviewed in the March 2013 issue of SOS, but Apogee have already released an updated version of the design suitable for use with both iOS devices and Macs and, to make this absolutely clear, the new name is Duet For iPad & Mac.

Duet Display Mac

The plus points noted in the Duet 2 review remain: typical Apogee sound quality, a useful (but small) OLED screen, assignable touch-pads... But by revising the internal hardware to support iOS devices, Apogee have significantly widened the appeal of the Duet to include all those who wish to make high-quality audio recordings on a mobile device as well as on their Mac.

The rear panel of the new Duet features a further socket that will please those of you who held off buying the Duet 2 because of its lack of MIDI support: a USB type A socket supporting 16 channels of MIDI I/O. It has to be said, though, that the omission of a USB cable from the supplied cables seems a little stingy on Apogee's part, especially given that this is not exactly a budget interface. On the other hand, you do get a dock connector (old-style 30-pin) to mini-USB lead (which powers your device and conforms to Apple's 'Made For iOS' program), a mains adaptor and a breakout cable with two XLR/TRS combi input sockets and two TRS output sockets. Owners of iOS devices with Lightning connectors will need a suitable adaptor.

Most of the features of the free Maestro II software for Mac have been ported across to the free Maestro iOS app, including volume controls (which update the position they display depending on the position of the single hardware control) and switchable soft limiting to guard against clipping. One feature missing from the Maestro app is the ability to switch sample rate. Due to the nature of iOS, this is achieved within the app used for recording, if that app supports multiple sample rates. Rates of 44.1, 48 and 96 kHz are supported by iOS itself, so an app like Auria would allow you to record at this rate using the built-in hardware or the Duet, but you are only likely to hear the benefit using the Apogee. GarageBand's sample rate is non-selectable, and so remains fixed at 44.1 kHz.

I was, as usual, impressed with the sound quality afforded by Apogee's gain circuitry and A-D/D-A converters. The rogue noises noted in the Duet 2 review when adjusting input gain are still there, and are especially noticeable the first time you adjust gain after selecting a new channel; almost as if the pots are dirty! That's a bit odd, considering that this is an all-digital system.

The Duet 2 was a good bet for Mac, so this new Duet has become a great choice if you want an interface with independent headphone and speaker outputs that will support capture and playback of high-quality audio from both your Mac and your iOS device.
