  3. For those using a standard HDMI cable, connect it to the available port on either the Samsung HDMI adapter or multiport adapter. Then, connect the other end of the adapter to your device.
  4. Once you've successfully connected your phone or tablet, the Samsung DeX logo will appear on your monitor.
  5. Connect your mouse and keyboard via Bluetooth. Wired peripherals can also be used with a multiport adapter.
  6. That's it - you're ready to get started with Samsung DeX.
    Setup on a Smart TV
    Launched alongside the release of the Samsung Galaxy Note20, select devices can now use DeX with a Smart TV. As long as the TV in question has Miracast, you'll be able to wirelessly connect in seconds.
