6 Ways to Use Your Android as Second Monitor For Your Computer

Attaching a Second display to your existing Computer setup can be a huge productivity boost but before you hit the buy button on Amazon, ask yourself do you need a dedicated Monitor all the time? If your answer is some times, then I have the perfect solution for you.

If you own an iPad, you must have heard Duet Display– a popular second monitor app for iPad. Thankfully, Android has them too. We tested almost every second monitor app for Android on the Google Play store, and here are our top picks. Let’s begin.

Use Your Android as a Second Monitor

Android smartphones and tablets are pretty versatile in terms of features, you can mirror your Android to another Android and as well as a computer. In general, you need need to install a second monitor app on your Android and install the app’s client app on your computer. Once done you can connect your Android to your computer, using a USB cable or WiFi (when both the devices are connected to the same network) and that’s it.

1. Spacedesk

Spacedesk is a popular choice to transform your Android into a second display monitor for Windows PC. You can connect your PC and Android via USB, Wi-Fi or LAN. The resolution is decent and you get touch support.

To get started, you need to install the necessary drivers on your Windows PC. If you need further help, here is a link to the documentation. The app is available for Windows 7 and above. Opening the app will automatically detect and display all PCs on the same server that has the drivers installed. Simply tap to connect. Launch the app on your Android and connect to your PC. The app should detect the IP address and name of your system.

To use your tablet or Android as an extended display, you just have to configure secondary display options in Windows. To do that go to the Control Panel and then Display Settings. Select Extend These Displays and click OK.  You should now be able to use your Android as an extended display.

Spacedesk works well if you don’t want your phone to be bounded by a USB. But that’s the only complaint I have. Since it works wirelessly, there is a noticeable amount of lag. It’s good that you can switch to hotspot and USB.

Supported Medium: LAN, Wi-Fi, USB

2. Splashtop Wired XDisplay

Splashtop Wired XDisplay, as the name suggests, will require you to have a USB handy. Unlike Spacedesk, WiredXDisplay allows you to connect your phone only via USB. On the plus side, since you are connected by a wired medium, you get better resolution and frame rate. It supports Full HD resolution at 60 frames per second.

Wired XDisplay can be installed on both Mac and PC, giving it an edge over Air Display. Mobile apps are available for both Android and iOS. Splashtop uses USB over WiFi for one simple reason – it offers a more responsive and real-time experience. There is no lag whatsoever and you get a battery saver mode which drops the frame rate and resolution to save up on processing.

Supported Medium: USB

3. Google Remote Desktop

Like Remote Desktop for Windows, it also allows you to control your PC via your Android device. You can run commands on your PC from your Android phone. Basically, everything that you can do on your desktop can be done from the Android phone as well. Remote Desktop, like all Google products, is easy to use and simple to set up. You just need to have a working Gmail account. The ability to control your PC remotely is where it shines the most though.

Google Remote Desktop works seamlessly but you cannot use separate apps on both the screen. It doesn’t let you use your phone as an extended display.

Supported Medium: Internet

4. iDisplay

iDisplay is another display mirroring app on this list. iDisplay started with the macOS and iOS but quickly expanded to other Operating systems. You have apps for Windows and Android which makes it a good cross-platform solution. It supports 60 fps and plus offers multi-touch on the device you are using it on.

iDisplay has everything that the other app offers, with one caveat; USB support is not available for Android yet. It does support WiFi though and comes with multi-touch support.

Supported Medium: LAN, Wi-Fi, USB (except Android)

5. Air Display 2

Air Display 2 works the same way for Mac the way Spacedesk does for Windows PC but it comes with a price of 14.99$. It turns your Android device into a secondary screen for your Macbooks. You can extend mirroring the screen to up to 4 secondary devices. On top of that, it also supports full HD displays.

It supports all the way back to Mac OS X 10.8 or Lion. You can also use your PC as a secondary screen for your Mac. But it doesn’t work the other way round like you cannot use Mac or any mobile device as a secondary screen for Windows. I read the FAQs section and it says they are working on a solution, but it also says that they are not “close enough” to provide an ETA.

On the plus side, it offers a more responsive experience thanks to the dynamic compression algorithm the team is using. It also supports retina display, something that is missing in Spacedesk. App also features Air Stylus which you can actually use the secondary device to draw designs on directly.

Air Display works seamlessly but the issue is the pricing model. With every major upgrade Avatron Software i.e. the creator of Air Display increases the price. This is something that bothers long-time users like me but hey if money is not a problem then you are good to go. Another thing that bugs me is that you need to install Air Display Host on your iPhones, Androids, and PCs which you want to use as a secondary screen. But, Air Display can only be installed on Macs. So the cross-platform compatibility gets a little limited.

6. Duet Display

Duet Display is a popular iOS app that allows you to mirror and extend your Mac’s display to your iPad or iPhone. And now that Apple is providing this feature natively via Sidecar, Duet Display is expanding its horizons with support for Android smartphones and tablets.

Duet Display invited us to beta test their new app, and it worked fine on my Google Pixel and Windows 10. Although, I did encounter a few bugs such as connection breaks. Also, while you can connect your Android Smartphone wirelessly to a Windows computer, you still need to attach a USB cable if you want to use the Android app with macOS.

The app is competitively priced at $9.99 and offers a lot of features and supports a wide range of devices. You can get the app for both Android and iOS devices.
