3 Way To Use Your Tablet Or Phone As Second Monitor For Your Computer For Free

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
