Multi-display utility tool for PC
Spacedesk is a free utility tool that was developed by datronicsoft for desktop PCs. It is a productivity application that allows users to create additional displays on Windows by using their phones or Surface tablets. This tool provides them with options to either duplicate or extend their main desktop to another screen.
Similar to how Miracast works on Android devices, Spacedesk provides users with the ability to use their Windows phone or Surface tablets as external displays in which to mirror or extend their computer desktop. Connect displays to one another using wired or wireless connections in your local network.
How do I use Spacedesk?
Before installing and using Spacedesk, you must first have the necessary drivers installed across all the devices you'll use it on, namely the Windows Desktop Extension and Windows Desktop Duplication. Both software are available to download from the developer's website. The app is compatible with Windows versions 7, 8.1, 10, and Windows 11. While it has support for dual or multi-display setups.
To connect your devices to one another in Spacedesk, you can use your local area network (LAN) through either wired or wireless connections. Ensure that your devices support the TCP/IP network protocol, though. Also, make sure all your devices are connected to the same network for seamless operation. Alternatively, you can use Mobile Hotspots or USB tethering for connections, as well.
Interacting and moving across displays is done using your keyboard and mouse on your desktop PC, or the touchpad—with support for various touch gestures—on your laptop. The program could use improvements in some areas, though. For one, there's quite a bit of lag present when using it, even with just two devices. Another is that connectivity can be inconsistent at times.
A handy tool for multi-display work setups
Spacedesk offers a free solution for creating multi-display work setups, and it does it well enough. It supports various connectivity options for your devices, input devices work well enough, and it's simple and easy to use. Lag and some connectivity issues are present, but for what it is, it gets the job done.
