How to Simulate Secondary Display in Android Samsung

 

To simulate a secondary display on an Android Samsung device, you can use features and apps that extend your screen functionality or allow multitasking on multiple screens. Here’s how you can simulate a secondary display:

### 1. Samsung DeX (Desktop Experience)

Samsung DeX is a built-in feature on many Samsung Galaxy devices that allows your phone to act as a secondary display or transforms your phone into a desktop-like experience when connected to a monitor, TV, or even a laptop.

#### Using Samsung DeX:

- On an External Monitor or TV:

   1. Connect your Samsung phone to a monitor or TV using a USB-C to HDMI cable, or use wireless DeX (available on newer models).

   2. Your phone will automatically switch to DeX mode, which offers a desktop-like interface on the external screen.

   3. You can still use your phone as a second screen, interacting with apps on the phone itself while the desktop is displayed on the monitor or TV.

- On a PC or Laptop:

   1. Install the Samsung DeX app on your Windows or Mac PC.

   2. Connect your Samsung phone to the computer via a USB cable.

   3. Once connected, your PC will display the DeX interface, and you can use your phone as a second screen to manage tasks or apps while the PC handles the desktop interface.

### 2. Multi-Window Mode (Split Screen)

Samsung devices have a multi-window mode that lets you run two apps simultaneously on your phone screen, which can simulate a dual-display-like experience by allowing you to work with two apps at once.

#### How to Use Multi-Window Mode:

1. Open one app.

2. Swipe up from the bottom of the screen to bring up the Recent Apps view.

3. Tap on the app’s icon and select Open in split-screen view.

4. Choose another app from your recent apps or app drawer to open in the second half of the screen.

5. Both apps will now run in a split-screen mode, and you can resize each window as needed.

### 3. Third-Party Apps for Wireless Secondary Display

You can also use apps that allow you to use another device (such as a tablet or PC) as a secondary display for your Samsung device.

- Spacedesk: This app allows you to wirelessly extend your display to a tablet or another device, simulating a secondary display. 

#### How to Use Spacedesk:

1. Install Spacedesk on both your Samsung device and the second device (e.g., a tablet or PC).

2. Ensure both devices are connected to the same Wi-Fi network.

3. Open the Spacedesk app on both devices and follow the instructions to connect them.

4. Your secondary device will now act as an extended screen, allowing you to drag windows or apps across devices.

- Duet Display: This app allows you to use your phone or tablet as a secondary screen for your PC or Mac. After installing the app on both devices, you can extend your computer’s display to your Samsung phone or tablet.

### 4. Second Screen Mode via Wi-Fi Display

Some Samsung tablets and devices support Second Screen Mode, which allows them to act as a secondary display when paired with a PC via Wi-Fi.

#### How to Use Second Screen:

1. On your tablet, go to Settings > Advanced Features > Second Screen.

2. Enable Second Screen mode.

3. On your PC, connect to your Samsung tablet as an external display using Projecting to this PC under the display settings.

4. Your Samsung tablet will act as a second display for your PC, allowing for an extended workspace.
