If you’re into some hardcore multitasking on your Windows PC, a second screen can go a long way. With an extended second display, it’s as if you have two Windows computers each with its own desktop. You can open apps in these side by side and copy and paste stuff between them. A second monitor can be a bit expensive though. It’s even non-practical if you don’t feel the need for one that often. So what do you do when that one time your desktop feels like it could use a second screen? You use your Android device as the second screen for your Windows PC. This is possible with an app called Spacedesk.

Of course, it’s possible. As long as you don’t mind installing a third-party software on your PC and its companion app on your Android. Spacedesk works wirelessly over Wi-Fi so there are no messy wires involved. This way, your second monitor is only a couple taps away even as you work on your light and compact Laptop at a Starbucks.

Before anything, you will need Spacedesk drivers installed on your Windows PC. These can be downloaded from the link given below. When you visit the link, you will notice a 32-bit and a 64-bit installer listed under the Spacedesk DRIVER software for Windows Primary PC (server) section. Modern PCs are all based on the 64-bit architecture. So if you have a laptop or PC that you bought within the last 5 years go ahead and download the 64-bit MSI installer.
