What You Need Before You Start
Before you set up your Samsung tablet as a second monitor, make sure you have the right tools. This will save you time and avoid connection issues later.
- ✅ A Samsung Galaxy tablet that supports Second Screen (Tab S7, S8, S9, or Tab S6 Lite 2022 version)
- ✅ A Windows 10 (version 2004 or later) or Windows 11 computer with Miracast support
- ✅ A stable Wi-Fi connection or a USB cable if you prefer wired
- ✅ Updated software on both devices (learn how to update your tablet)
💡 Tip: Not all Windows PCs support Miracast. If yours doesn’t, you’ll need to use a wired app solution like SuperDisplay or Duet Display.
How to Use Samsung Tablet as Second Monitor with Built-in Second Screen Mode
Samsung tablets have a built-in feature called Second Screen that makes it easy to turn your tablet into an extra monitor.
The Second Screen feature allows your tablet to act as an extra monitor for your computer. It connects wirelessly and lets you either extend your display or mirror it. This gives you more workspace without needing an external monitor.
Steps to Enable Second Screen Mode
- On your tablet, open Quick Settings and tap Second Screen.
- Choose between Extend (extra workspace) or Duplicate (mirror your screen).
- On your Windows PC, press Windows + P and select Connect to a wireless display.
- Pick your tablet from the list and wait for the connection.
Now your tablet will act as a second monitor. Keep in mind that only certain models support this feature, such as the Galaxy Tab S7, S8, S9 series, and the 2022 version of the Tab S6 Lite. The original 2020 Tab S6 Lite does not support Second Screen.
💡 Tip: Second Screen can drain your tablet battery quickly during long sessions. Keep your tablet plugged in for the best experience.
How to Use Samsung Tablet as Second Monitor with Samsung DeX
Samsung DeX is another built-in tool that creates a desktop-like experience on your tablet. While it is not the same as Second Screen, it is still useful if you want to multitask in a more computer-style environment.
What is DeX Mode on Samsung Tablets?
DeX mode is a special interface that lets you open multiple windows, drag apps, and multitask like you would on a desktop.
It does not extend your PC display but instead turns your tablet into its own desktop workspace.
How to Use Samsung DeX as a Second Monitor
Samsung DeX cannot extend your PC screen in the same way as Second Screen. Instead, it allows you to use your tablet as a standalone desktop environment while still connected to your computer.
This can be helpful if you want to run apps on your tablet while working on your main PC at the same time.
Setting Up Samsung DeX
- Connect your tablet to your PC with a USB cable or wirelessly if supported.
- Enable DeX mode from your tablet’s Quick Settings.
- Your tablet will now display a desktop interface where you can open apps, drag windows, and multitask.

How to Use Samsung Tablet as Second Monitor with Third-Party Apps
If your Samsung tablet does not have the Second Screen feature, you can still use third-party apps to achieve the same result.

- ✅ Duet Display: Works with both Windows and Mac computers.
- ✅ Splashtop Wired XDisplay: Great for wired connections with low delay.
Each app has its own setup steps, but generally you will need to install the app on both your computer and tablet, connect them with Wi-Fi or USB, and then adjust your display settings.
Wired vs Wireless Connection: Which One Should You Choose?
When deciding how to connect your Samsung tablet as a second monitor, you can go wired or wireless. Each option has its strengths.
Wired Connection
- ✅ Faster response time
- ✅ No lag
- ✅ Best for gaming or video editing
