Sending video to a Roku device has become one of the most common requests in the world of streaming, whether you are showcasing a vacation montage, sharing a home movie, or presenting a business proposal. The good news is that the process is straightforward, thanks to a combination of native casting features and robust third-party applications. This guide walks through the primary methods, highlighting the nuances of each so you can get your content on the big screen without unnecessary friction.

Understanding Casting vs. Screen Mirroring

Before diving into the "how," it is essential to understand the "why" behind the two main technical approaches: casting and mirroring. Casting is the efficient process of streaming a specific video file from your phone to the TV, leaving your mobile device free to perform other tasks. Screen mirroring, on the other hand, replicates your entire phone display on the Roku screen, which can lead to lag but is necessary for apps that do not support native casting.
Method 1: Native Casting from the Roku App

Roku provides its own official mobile application, which serves as the most direct conduit for sending media. This app bypasses the need for complex network configurations and leverages your Wi-Fi connection to deliver media files directly.
Steps to Send Video

- Ensure your phone and Roku are connected to the same Wi-Fi network.
- Download the official "Roku" app from the App Store or Google Play Store.
- Open the app, select your Roku device, and tap the "Media" icon.
- Navigate to the video stored on your phone and initiate playback.
Method 2: Using Apple AirPlay
For users within the Apple ecosystem, AirPlay offers a seamless, low-latency experience. If your Roku is a 4K model or a modern ultra model, it likely supports AirPlay 2, turning your television into a high-quality receiver.

Steps to Send Video
- Swipe down from the top-right corner of your iPhone or iPad to access Control Center.
- Tap the Screen Mirroring or AirPlay icon.
- Select your Roku television from the list of available devices.
- Enter the on-screen code if prompted, then play your video from the Photos app or within a compatible third-party app.
Method 3: Google Cast for Android

Android users have robust native support for Chromecast technology, which is often built directly into the Roku hardware. This allows for a "send to TV" experience that is integrated into the operating system.
Steps to Send Video




















- Install the "Google Home" app if it is not already on your device.
- Tap the Cast icon (usually located in the top right corner of a video or within the app drawer).
- Choose your Roku device from the list.
- Once connected, the video will play on the television while your phone locks or switches to other apps.
Method 4: Third-Party Solutions for Non-Compatible Content
Not all video formats are created equal, and some streaming services or downloaded files may not offer a cast icon. In these scenarios, a workaround is required. DLNA (Digital Living Network Association) servers allow you to stream media that your Roku can read without relying on a direct connection from the source device.
Recommended Apps
- BubbleUPnP: This app turns your phone into a server, hosting videos stored locally or on cloud storage. You navigate the content through the BubbleUPnP interface on the TV using the Roku remote.
- Kodi: A powerful media center app that can organize and stream a vast library of video. By setting up a Kodi server on a PC or NAS, you can access that library on the Roku via third-party Kodi controllers.
Troubleshooting Common Connectivity Issues
Even with the right method, technical hurdles can arise. If your video refuses to send, the issue is usually one of three things: network integrity, software version, or settings configuration.
Check the Network
Roku requires a stable 2.4 GHz or 5 GHz Wi-Fi signal. 5GHz generally offers less interference for streaming 4K content, but if your router is far from the TV, 2.4 GHz might be more reliable. Ensure no bandwidth-heavy downloads are occurring on other devices.
Update Your Software
- Roku Device: Navigate to Settings > System > System Update to ensure the firmware is current.
- Mobile App: Visit the App Store or Play Store to update the official Roku or casting apps.
Verify Settings
On the Roku device, go to Settings > Network and verify that "Wireless Device Display" is enabled. This setting is required for phones to "see" the TV.
Recommendations for Specific Use Cases
Choosing the right method depends heavily on what you are trying to achieve. For quick personal sharing, native casting or AirPlay is the gold standard. For professional settings or rotating playlists, a DLNA server provides stability. If you are using older Roku models that lack AirPlay or modern casting protocols, the DLNA method is often the only reliable solution for sending high-definition video without purchasing new hardware.
