How to Use Your Tablet as an Additional Monitor

This tutorial uses a third party tool called Spacedesk. While reputable, it's worth remembering that any third-party application that can share a screen could snoop on what's displayed. We don't recommend using a third-party screen sharing app for tasks which require strict security.

Follow the steps below to turn your Android tablet into a second monitor.

The method uses a third-party application called Spacedesk that is compatible with all modern Android devices. You will need a Windows computer that runs Windows 8.1, Windows 10, or Windows 11, and a Wi-Fi connection accessible to both your Windows computer and Android tablet.

  1. Open a web browser and visit the Spacedesk website.

  2. Click Download, then download the version of Spacedesk driver software designed for the version of Windows you use.

    You will also need to choose between a 64-bit or 32-bit installer. Most modern Windows computers require a 64-bit installer.

    If you aren't sure which to choose, here's how to find out if you have 64-bit or 32-bit Windows.

FAQ
  • Can a Tablet be Used as a Monitor?

    Yes. While Windows handles this through screen-sharing and Apple has a feature for macOS and iPadOS called Sidecar, Android doesn't offer a similar official feature. When it comes to Android, third-party apps like Screendesk are the only option.

  • How do I connect an Android tablet to a monitor?

    With some cables and adapters, you can connect an Android tablet to a monitor and mirror its screen there. The ones you need will depend on the connections available on both devices, but it's easiest if the monitor has an HDMI port to handle both picture and sound. USB-C-to-HDMI adapters are available at most electronics retailers.

  • What other apps can I use for using an Android tablet as a monitor?

    Screendesk is not the only app to support using an Android tablet as a monitor. Possible alternatives include Twomon, Splashtop, SecondScreen, and SuperDisplay. These are worth a try if Screendesk doesn't work on your computer.
