Screen mirroring allows you to wirelessly connect your device to your Roku TV, mirroring your screen on the big screen. It's like having a giant monitor for your phone, tablet, or computer!
To get started, make sure your Roku TV and device are connected to the same Wi-Fi network. Then, on your device, go to the settings menu and look for the screen mirroring option. It might be called Miracast or Smart View, depending on your device.
