One of the reasons some people purchase an Apple TV is because it allows you to mirror your iPhone’s screen on your TV, which lets you display photos and videos, as well as play music stored on your phone.

But if you already have a Roku streaming device, you might not need an Apple TV.

You’ll just need to make sure the Roku is configured for mirroring in its settings, and you’ll need to use the Roku app on your iPhone. The app lets you display iPhone photos and videos on your Roku, as well as stream music stored on your phone.

3. Choose the type of content you want to send to your Roku. You can choose Music, Photos, or Videos stored on your iPhone.

When you choose a photo from a folder on your phone, the photo will appear on your TV via the Roku, and the Roku will play the photos in the folder as a slideshow. You can manually control the slideshow using the buttons below the photo to skip, go back, and pause or play the show.

If you want to change the slideshow speed or add transitions between the photos, tap the gear icon to the right of the player controls.
