If you want to mirror your iPhone or iPad screen to your Roku TV without using WiFi, there are a few different methods you can try. The first option is to use an HDMI cable. This will allow you to mirror the screen directly from your device to the TV. However, this method is not ideal because it will use up a lot of bandwidth and may be slow depending on the connection between the devices. Another option is to use AirPlay Mirroring. This allows you to stream content from your iPhone or iPad directly to the Roku TV. However, this method is also not ideal because it requires a strong Wi-Fi connection and may not work if there are any walls between the devices. The final option is to use a app like AirMirror. This app allows you to mirror your iPhone or iPad screen without using any cables or apps. It works with both iOS and Android devices and has a variety of features, including support for subtitles and audio playback. ..
