How to Use Android Phone as Second Monitor for Windows 10/11 PC

Android smartphones and tablets are incredibly flexible when it comes to what they can do. You can actually mirror your Android screen to another Android device or even a computer. Basically, you just need to grab a second monitor app on your Android and then install the app’s client counterpart on your computer. After that, it’s just a matter of connecting your Android to your computer via USB cable or over Wi-Fi (as long as both devices are on the same network), and you’re good to go!

Here’s how it’s done:

Note: Make sure that both the devices are connected to the same Wi-Fi network.

1. Download and install the Spacedesk software for both your PC and Android phone.

• Right-click on the desktop and then click Display settings.
