Your tablet is sitting in a drawer or on a shelf, barely used. What if it could become a second screen for your laptop or desktop? Learning how to turn a tablet into a monitor is simpler and cheaper than most people think. You skip the cost of buying new hardware while gaining real productivity.
The setup works by streaming your computer’s display to the tablet over Wi-Fi or USB. It functions as a true extended monitor for dragging windows, editing photos, sketching digitally, or just keeping chat apps visible. Both free and paid tools exist, and some brands like Samsung and Apple even offer built-in options.
In this guide, you will learn how to turn a tablet into a monitor using the best apps and native methods. You will also get troubleshooting tips, tablet recommendations, and creative ways to use your new dual-screen setup.
Use Space Desk for Any Tablet (Free)
Space Desk is the top free tool for turning almost any tablet into a working second monitor. It supports Windows PCs and connects to Android tablets, iPads, and even web browsers. There are no monthly fees, no watermarks, and no hidden limits.
Set Up Space Desk Wirelessly
Connecting over Wi-Fi takes only a few steps:
- Download the Space Desk driver from
spacesdesk.netonto your Windows PC. - Choose the correct installer: standard for Intel or AMD, ARM64 for Snapdragon devices like Surface Pro X.
- Install the Space Desk app on your tablet from Google Play or the App Store.
- Open the app and let it auto-detect your PC on the same network.
- Tap the PC name to connect.
Once connected, press Windows + P on your PC and select Extend. You can now drag windows, resize apps, and use touch on the tablet.
Pro Tip: For the smoothest experience, connect both devices to a 5GHz Wi-Fi network. Avoid crowded routers or long distances between devices.
Connect via USB for Low Latency
If you want smoother performance for drawing or gaming, use a USB cable instead:
- Plug your tablet into the PC using a USB-C or USB-A cable.
- Open the Space Desk console on your PC and select USB Cable (Android) or USB Cable (iOS).
- Authorize the connection if prompted, and enable USB debugging on older Android devices.
This wired mode dramatically reduces lag, stabilizes the connection, and often charges your tablet while you work.
Enable Touch and Audio Features
Space Desk supports more than just video streaming:
- Touch input lets you tap, swipe, and drag windows directly on the tablet.
- Audio routing sends PC sound to the tablet speakers. Tap the three-dot menu, then Audio, then Enable.
- Security options include password protection in the Space Desk driver settings.
- Performance tweaks let you adjust image quality, frame rate (up to 120 FPS), color depth, and resolution.
Try Super Display for Artists (Android Only)
If you are using an Android tablet for digital art, Super Display is worth the $14.99 one-time purchase. It is built specifically for creatives who need pressure-sensitive stylus support and high refresh rates.
Why Artists Prefer Super Display
Unlike general-purpose tools, Super Display delivers features that matter most to illustrators:
- Full S-Pen and stylus pressure sensitivity, supporting up to 8,192 levels.
- Smooth performance even on 2.4GHz Wi-Fi networks.
- Compatibility with Krita, Photoshop, Illustrator, and other design apps.
- Simultaneous file transfer over USB while streaming the display via Wi-Fi.
It works with most Android tablets and foldables, including Samsung Galaxy Tabs, Lenovo M10, and Xiaomi Pad models.
Install and Connect in Minutes
- Download the Super Display Windows driver and install it.
- Install the Super Display app from the Google Play Store on your tablet.
- Connect via USB-C or Wi-Fi.
- Authorize the connection when prompted.
After connecting, extend your display using Windows + P. Then calibrate the stylus in your design software for accurate pressure response.
Expert Note: For maximum responsiveness, use a USB-C to USB-C cable and disable battery optimization on the tablet.
Use Samsung Second Screen Without Extra Apps
Samsung Galaxy Tab S7, S8, S9, and S10 owners get a major advantage. Second Screen is built into One UI 3.1 and later, so no downloads are required.
Activate the Built-In Wireless Display
This native feature mirrors or extends your Windows PC screen without third-party software:
- On your tablet, swipe down from the top-right corner with two fingers.
- Tap the Second Screen icon.
- Choose a mode: Drawing/Gaming or Video.
- On your PC, press Windows + K to open the Connect menu.
- Select your tablet from the list.
Your PC screen appears instantly on the tablet. Use Extend mode to expand your workspace or Duplicate mode to mirror.
Optimize for Productivity
Fine-tune your setup with these adjustments:
- Adjust scaling in Windows Display Settings. Set it to 150% or 175% for readable text on smaller tablets.
- Switch to Portrait mode for coding, reading docs, or keeping chat apps visible.
- Use touch control to navigate with taps and swipes. The mouse cursor follows your finger.
If the tablet does not appear, check that both devices are on the same Wi-Fi. Confirm that Wireless Display is enabled in Windows Settings under System and Display. Disable any VPNs or temporarily turn off Windows Firewall.
Enable Apple Sidecar for iPad and Mac
For Mac and iPad users, Sidecar is the gold standard. It turns your iPad into a seamless second monitor with ultra-low latency, Apple Pencil support, and Touch Bar emulation.
Connect iPad to Mac Easily
- Make sure both devices use the same Apple ID and connect to the same Wi-Fi.
- On your Mac, open System Settings and go to Displays.
- Click the plus button or find your iPad under AirPlay.
- Select Add Display and choose Extend or Mirror.
You can also connect via USB-C cable for better stability and charging.
Unlock Creative Features
Sidecar shines for designers and creatives:
- Apple Pencil support lets you draw directly on the iPad while editing in Photoshop or Procreate.
- Touch Bar mode turns the bottom of the iPad screen into a customizable toolbar.
- Resolution matching automatically adapts to your Mac’s display settings.
No extra apps or drivers are needed. Just seamless integration across Apple devices.

Frequently Asked Questions About Turning a Tablet into a Monitor
Can any tablet be used as a second monitor?
Most Android tablets running Android 6.0 or higher and iPads running iPadOS 13 or later work as second monitors. You need a compatible app like Space Desk or a native feature like Sidecar or Samsung Second Screen to make the connection.
Is using a tablet as a monitor free?
Yes, free options exist. Space Desk is completely free for personal use and works with Windows, Android, and iOS. Samsung Second Screen and Apple Sidecar are also free built-in features on supported devices.
Does using a tablet as a monitor cause lag?
Lag depends on your connection type. Wired USB connections have near-zero lag, while Wi-Fi performance depends on your network. Using a 5GHz Wi-Fi band minimizes lag for wireless setups.
Can I use a tablet as a monitor for gaming?
