How To Do Screen Mirroring Samsung S9

Screen mirroring allows users to display the contents of their Samsung S9 smartphone on a larger screen, such as a television or computer monitor. This functionality offers a convenient way to share photos and videos, present presentations, or enjoy mobile games on a bigger display. Several methods facilitate screen mirroring from a Samsung S9. Choosing the right method depends on the target device and available equipment.

Using Smart View

Smart View is a built-in feature on Samsung S9 devices designed for easy screen mirroring to compatible smart TVs. Most modern Samsung Smart TVs support Smart View directly. Other television brands may also offer compatible functionality under a different name. Check the television's user manual for information on supported wireless display technologies.

To use Smart View, firstly ensure both the Samsung S9 and the smart TV are connected to the same Wi-Fi network. Then, swipe down from the top of the S9 screen to access the Quick Settings panel. Locate the "Smart View" icon and tap it. The phone will then search for available devices. Select the desired television from the list. A connection prompt may appear on the television; confirm to initiate the mirroring session.

Utilizing a Chromecast Device

Chromecast is a small, affordable device that plugs into a television's HDMI port, enabling screen mirroring and streaming capabilities. This method works with a wider range of televisions, irrespective of brand or smart functionalities, as long as they possess an available HDMI port.

To mirror to a Chromecast, ensure both the Chromecast and the Samsung S9 are connected to the same Wi-Fi network. Open the Google Home app on the S9. Select the Chromecast device from the list of available devices within the app. Tap the "Cast Screen/Audio" button. A confirmation prompt will appear; tap "Start Now" to initiate the screen mirroring session.

Connecting to a Windows PC with the Your Phone Companion App

Microsoft's Your Phone Companion app allows for screen mirroring to a Windows 10 or Windows 11 PC. This method provides a convenient option for users who want to display their phone screen on their computer monitor.

To utilize this feature, install the Your Phone app on the Windows PC and the Link to Windows app on the Samsung S9. Ensure both devices are connected to the same Wi-Fi network and signed in with the same Microsoft account. Open the Your Phone app on the PC and follow the on-screen instructions to link the S9. Once linked, select the "Phone screen" option within the Your Phone app to initiate screen mirroring.

Wireless Display Adapters (Miracast)

Wireless display adapters, often based on the Miracast standard, offer another means of screen mirroring. These devices plug into the HDMI port of the television and create a wireless connection point for the S9 to connect to.

To use a Miracast adapter, connect the adapter to the television's HDMI port and power it on. On the Samsung S9, swipe down from the top of the screen to access the Quick Settings panel. Locate and tap "Smart View." Select the wireless display adapter from the list of available devices. Follow any on-screen prompts on both the television and the S9 to complete the connection and initiate screen mirroring.

Troubleshooting Common Issues

If encountering difficulties with screen mirroring, several troubleshooting steps can be taken. First, ensure both the S9 and the target device are connected to the same Wi-Fi network and that the network has a stable internet connection. Restarting both devices can also resolve temporary connection glitches. Check for software updates on both the S9 and the target device, as outdated software can sometimes interfere with screen mirroring functionality. If using a specific app, ensure the app supports screen mirroring, as some apps may restrict this capability.

Using Third-Party Apps

Numerous third-party apps available on the Google Play Store facilitate screen mirroring. Researching and selecting a reputable app can offer additional features or compatibility options not available through built-in methods. Carefully review the app's permissions and user reviews before installation.

Connecting with Cables (DeX Mode)

While not strictly screen mirroring, Samsung DeX mode transforms the S9 interface into a desktop-like experience when connected to a monitor or TV via a USB-C to HDMI adapter and cable. This method offers a more interactive experience than traditional screen mirroring, allowing for the use of a mouse and keyboard with the S9 on the larger display. To utilize DeX mode, connect the necessary adapter and cable to the S9 and the display. The S9 will automatically switch to DeX mode upon connection.
