Extend or Mirror a Windows Desktop
spacedesk turns an Android phone or tablet into a secondary display for a Windows computer. After the spacedesk Driver is running on the primary PC, the Viewer can show an extended desktop for extra workspace or duplicate the existing screen for presentations and monitoring. This gives an unused mobile device a practical role beside a laptop or desktop monitor.
The connection screen keeps the workflow focused on the primary machine rather than files or cloud accounts. Once connected, Windows windows can move onto the Android display, while mirror mode can keep the same content visible on both screens. The setup is useful for timelines, reference material, chat panels, dashboards, and other tasks that benefit from a separate view.
Discover a PC or Enter Its Address
The Viewer can look for a spacedesk primary machine on the local network and list an available server for quick selection. If automatic discovery does not find the computer, the plus control opens a manual connection form where users can enter the primary PC's IP address. This offers a direct fallback for networks where device discovery is limited.
Connections can use Wi-Fi, LAN, or a supported USB path, but the Windows computer must have the spacedesk Driver installed and active. LAN use normally places both devices on the same network, while USB can provide a wired option for compatible Android setups. Keeping the Viewer and Windows Driver current helps avoid version mismatches before starting a display session.
Control Windows with Touch and Input Tools
spacedesk is more than a passive display when remote input is enabled. Android users can work with touchscreen control, pointer gestures, an on-screen or hardware keyboard, and supported pen input, allowing the secondary screen to act like a touch panel, trackpad, or drawing surface for the Windows desktop. These controls can reduce the need to reach for the primary computer during a session.
The Viewer menu groups Input Devices with Settings, the user manual, technical support, licensing, and app information. This makes input behavior and troubleshooting help accessible from one place. Practical uses include sketching with a stylus, navigating a presentation from the tablet, entering text, or controlling a window positioned on the secondary display.
Build a Portable Multi-Monitor Setup
A phone or tablet running spacedesk can add workspace without carrying a conventional monitor. Travelers can keep notes, communication tools, or reference pages on the Android screen, while office users can dedicate it to status panels or media controls. Mirroring also suits demonstrations where another person needs to see the Windows desktop nearby.
Connection quality depends on the network path, device, resolution, and encoding settings, so users can choose between wired and wireless arrangements to match the situation. A direct local connection can work without public internet access, provided the Viewer can reach the Windows Driver. This flexibility makes spacedesk useful for temporary desks, presentations, creative input, and compact dual-screen layouts.
