Android Tablet As A Second Display

While monitors aren’t prohibitively luxurious, an Android tablet is an ideal alternative for a second display if you own one. In order to set up an Android tablet as a secondary display, you have to download an app. There are several apps available that makes a tablet into an additional screen. Two of the most well-known are ScreenSlider by Redfly and iDisplay by Shape.

ScreenSlider only supports Android/Windows, while iDisplay is compatible with Android, Windows, iOS and Mac. Air Display is another alternative as well. We have selected iDisplay as it works across different platforms.

Using iDisplay With Android Tablet:

1. Install iDisplay app from Google Play Service.

2. On your desktop, go to Getidisplay site and click on the Windows download button and select your Windows operating system on the resulting page.

3. Follow the instructions to install the drivers and softwares. Now restart your computer when prompted. Allow the installed software to get access through the PC’s firewall by clicking on the Allow Access button on the Windows Security Alert dialog that, which will be visible once the system restarts.

4.  Ensure that your PC and Android device are connected to the same local network.

5. Find iDisplay icon in the Taskbar Notifications Area on your machine. Hover your mouse over it; you’ll see a port and IP address. Note them correctly.

6. Launch the iDisplay app on your Android tablet. Tap the “+” button; enter the IP address, port and any description that you’d like to give your PC. Your configuration may not even need this step. Look for a button to automatically connect to your PC when you first launch the app. When you connect from your tablet, a dialog box will come up on your PC asking if you want to permit the connection.

7. After that, blank extended PC desktop will appear on the Android device. Visually locate the mouse pointer and move it between screens with the PC’s mouse. Take the control and movement with your finger as the mouse pointer transitions to the Android device’s touchscreen.


You need a compatible tablet running Android 3.01 or above and your computer should have Windows XP, Vista or 7 (32-bit or 64-bit).

When you launch a program on the desktop, you can drag it over to your Android device and work with it using touch. One tap on the Android screen will put the mouse pointer on that screen. Touching the trackpad or mouse will move the mouse pointer onto the desktop’s screen.

You can use the PC’s keyboard to enter text in programs on the Android device’s screen. Click Disconnect in the iDisplay notification icon in the Taskbar Notifications Area on the PC’s desktop, in order to close the connection. Use the back button on your Android device to close the app.
