Set up Samsung DeX on your phone or tablet

Phone connected to PC with Samsung DeX

Are you tired of squinting to get a better look at images? When you want to see every detail of an image or video, use Samsung DeX. It lets you connect your mobile device to a TV or monitor for a larger and clearer view on an amazing desktop mode. Your eyes will thank you!

Note: Available screens and settings may vary by wireless service provider and software version.

Use the DeX cable

Connect the USB-C end of the DeX Cable to the port on the mobile device, and then connect the HDMI end into a TV or monitor's HDMI port.

If you want to use a keyboard and a mouse, you can connect Bluetooth devices directly to the mobile device to use them in Samsung DeX.

The DeX cable is supported from the Galaxy Note9, Galaxy Tab S4, Galaxy Fold, and the Galaxy S10e/S10/S10+ and newer devices.

Your mobile devices’ screen should appear on the monitor. Unlock the device if you have a screen lock. A popup message will display on your Home screen. Tap OK to allow access to Full Desktop mode. Next, a Samsung DeX notification will appear. Read the introductions and instructions on the monitor. When you’re done, select I agree to the Terms and Conditions above, and then select Start.

Note: You can use the mobile device's screen as a touchpad and keyboard.

Use the DeX Pad or Station

You're going to ace that research project when you can work on it from the big screen. There's two things you need to do:

Connect the DeX Pad or Station to the Fast Charging Travel adapter that came with the phone. Connect one end of an HDMI cable to the DeX's HDMI port, and then connect the other end into a TV or monitor's HDMI port.

Next, connect your phone to the DeX Pad or Station. If your phone has a case on it, make sure you take it off before connecting as it may cause connection issues. If you want to use a keyboard and a mouse, connect them to the USB ports on the DeX. You can also connect Bluetooth devices, such as a Bluetooth keyboard and mouse.

Note: The DeX Pad is supported by the Galaxy S8, Galaxy S8+, Galaxy S8 Active, Galaxy 9, and Galaxy S9+, Note8, and Note9. The DeX Station is supported by the Galaxy S8 and Galaxy S8+.

Once everything is connected successfully, slide the DeX Station cover open, mount the phone onto the USB-C connector, and select the screen mode you want to use. You can select Samsung DeX or Screen mirroring mode.

  • START SAMSUNG DeX: The phone's screen will turn off and appear on the connected TV or monitor in desktop mode.

  • SWITCH TO SCREEN MIRRORING: The same screen as the phone will appear on the connected TV or monitor.

Samsung DeX settings

When you connect your mobile device to a DeX product, Samsung DeX Settings are added to your Settings list. To access it, select Settings from the Home screen, and then select Samsung DeX. From here, you can customize your wallpaper or screen resolution for Samsung DeX, access keyboard and mouse settings, try new features in advance with Samsung DeX Labs, or learn how to use Samsung DeX. Let the exploring begin!
