Steps
Download the spacedesk driver from spacedesk.net and install it on your Windows PC. Restart the computer if the installer asks you to.
Connect your PC and your tablet to the same Wi-Fi network. A 5 GHz network usually gives smoother video than a crowded 2.4 GHz one.
Install the spacedesk app on the tablet from Google Play or the App Store.
Open the spacedesk app on the tablet. It scans your network and lists any PC running the driver by name.
Tap your PC name to connect. Approve the pairing prompt on the Windows side if one appears.
Right-click an empty spot on the desktop, open Display settings, and choose Extend these displays so the tablet becomes a second screen instead of a copy.
Press Windows + P at any time to switch quickly between Extend, Duplicate and PC screen only.
In Display settings, drag the numbered screen boxes to match where the tablet physically sits, then click Apply.
Set the tablet's resolution and orientation in the same Display settings window, and turn off auto-lock so the screen stays awake.
Tips and common mistakes
Keep the tablet plugged into a charger, because a screen running for hours drains the battery fast.
Expect a small lag over Wi-Fi. If video feels choppy, move both devices closer to the router or use a 5 GHz band.
If the tablet cannot find the PC, allow spacedesk through Windows Firewall and check both devices are on the same network, not one on mobile data.
Set the tablet screen timeout to Never while it is acting as a monitor, or it will sleep and drop the connection.
Questions
Is spacedesk free?
Yes, the Windows driver and the tablet app are free for personal use. You only need a working Wi-Fi network.
Can I use an iPad as the second screen?
Yes, spacedesk has an iOS app. Install it on the iPad, connect to the same Wi-Fi as the PC and tap your computer's name in the list.
Why does the tablet screen look blurry or stretched?
The resolution or orientation does not match. Open Display settings on the PC, select the tablet screen and pick a resolution close to the tablet's native one.
