To start screen mirroring, make sure your Roku TV and device are connected to the same Wi-Fi network. Then, go to your Roku's settings and select Screen Mirroring. On your device, look for the mirroring option - it might be called Miracast or Screen Sharing.
Once you've enabled screen mirroring on both devices, you should see your device's screen appear on your Roku TV. It's like magic, right? Now you can play games, watch videos, or browse the internet on the big screen.
