Mirroring is a live video stream, so it rewards a fast decoder and a clean network connection. The Ultra sits on your shelf rather than behind the TV, and with Ethernet it doesn't compete with your phone for Wi-Fi at all.

Your phone has Smart View or Wireless display? The Ultra's built-in mirroring works too: turn on SettingsSystemScreen mirroring and pick the Ultra from your phone's cast menu.

Plug in Ethernet

This is the single biggest upgrade for mirroring. Run a cable from your router to the Ultra's Ethernet port, then choose SettingsNetworkSet up connectionWired. Your phone stays on Wi-Fi — that's fine, the two still talk across your home network.

Same network, not same connection typeA wired Roku and a phone on Wi-Fi work together as long as both are on the same router. They only fail to see each other if the phone is on a guest network or the router isolates wireless devices.

Best settings for mirroring

  • Instant Video for apps, games and presentations — the lowest delay.
  • Screen + Sound for videos and music — sound plays through your TV or soundbar (Android 10+).
  • Turn your phone sideways for video so it fills the screen.
  • For photos and home videos, use Cast Photos and Cast Videos — the Ultra plays the original file at full quality.

Wondering about 4K? Mirroring runs at up to 1080p even on the Ultra — here's why, and how to get true 4K.

Lost the Ultra's remote?

Most Ultras have a lost-remote finder button on the player itself: press it and a compatible remote plays a sound. Until you find it, your phone works as a full remote — see how to control your Roku without a remote.
