The setup process is the same for all the devices. First, you have to install the spacedesk server app on your PC running Windows. And then, you have to install the spacedesk client on the other device which is Android in our case. After installing the respective apps, make sure that both devices are connected locally. The simple method to connect the devices is either via USB cable or over wireless LAN. In the case of wireless LAN, just connect both devices to the same network/WiFi.

After connecting both devices, open the spacedesk app on PC. The app shows you the computer name, connection status, and spacedesk driver version. Below that, it shows the local network interfaces and network connections in separate tabs.

Now, open the spacedesk app on your Android device. If both devices are connected to the same network, your PC would appear in the Android app. Tap that and the PC display will be automatically extended to your Android device.

The Android device will act as a secondary display for Windows PC. From the Windows display settings, you can either extend or mirror your desktop screen to Android. The Android screen supports touch input, instead of bringing the cursor to the secondary display, you can use the touch for interaction.

Closing Words

spacedesk is a handy utility app that lets you use almost any smart devices as a secondary display for Windows PC. It can be useful outdoors where you can not bring a secondary monitor with you. It is similar to the sidecar feature of macOS but with more versatility and device support. The only downside of this app is that it doesn’t use any encryption while transmitting data between devices. So, I recommend you not to use this on public networks, instead, use a personal hotspot on any of your devices for connection.
