How to Chromecast to Roku TV in 2026: Setup Guide

Trying to figure out how to Chromecast to Roku TV but still not seeing your TV or getting random disconnects? The problem often comes down to using the wrong casting method or a connection setting that doesn't match your devices.

This guide walks you through four ways to cast to Roku TV, including using an external Chromecast, casting from Android with PigeonCast, streaming through supported apps, and screen mirroring without Chromecast. You'll also find practical fixes for common connection issues.

Can You Cast to Roku via Chromecast

Yes, you can cast content to Roku TV, but Roku doesn't have built-in Google Cast support like a Chromecast device. If you're unsure whether Roku has Chromecast built in, the main difference is how each device receives content.

You can connect an external Chromecast to a Roku TV's HDMI port, use compatible apps that support casting to Roku, or mirror your screen through Miracast or AirPlay. PigeonCast also supports Android-to-Roku casting through its compatible connection methods, including Google Cast support.

Before starting, make sure your Roku TV is powered on and connected to the same local network as your phone or computer when using wireless casting. The exact steps depend on which method you choose.

How to Chromecast to Roku TV

There are several ways to get content onto your Roku TV, but they don't all use the same casting technology. If you already own a Chromecast, you can connect it directly through HDMI. Otherwise, you can use PigeonCast, a Roku-compatible app, or your device's built-in screen mirroring feature.

Method 1. Connect Chromecast to Roku TV via HDMI

If you have a Chromecast or Google TV streaming device, the most straightforward way to use Google Cast on a Roku TV is to connect it to an available HDMI port. This method gives you access to Chromecast's native casting features without depending on Roku's built-in receiving capabilities.

Step 1. Plug your Chromecast into an available HDMI port on your Roku TV and connect it to power.

Step 2. Turn on the Roku TV and use the remote to select the HDMI input where your Chromecast is connected.

Step 3. Follow the on-screen setup instructions to configure your Chromecast and connect it to your Wi-Fi network. Some Chromecast models use the Google Home app for initial setup.

Step 4. Connect your Android phone, iPhone, or computer to the same Wi-Fi network as your Chromecast.

Step 5. Open a Google Cast-compatible app, tap the Cast icon, and select your Chromecast device to start streaming.

You can also cast browser tabs or supported content from a computer using Google Chrome. For more browser-specific instructions, see our guide on how to cast Chrome to Roku TV.

Note: This method works with Roku TVs that have an available HDMI input. It doesn't turn Roku OS into a Chromecast receiver, and it doesn't apply to plugging a Chromecast directly into a Roku Streaming Stick.

Method 2. Use PigeonCast as a Chromecast Alternative for Roku

If you have a Roku Express or Roku Streaming Stick, buying a separate Chromecast device isn't your only option. PigeonCast works as a Chromecast alternative for Roku, allowing you to cast content from your Android phone without installing another app on your phone.

PigeonCast supports multiple casting protocols, including Google Cast, AirPlay, and DLNA. By installing it on your Roku device, you can add compatible casting capabilities that aren't available through Roku's built-in features.

Step 1. On your Roku TV, Roku Express, or Roku Streaming Stick, open the Streaming Store and install PigeonCast.

Step 2. Launch PigeonCast on Roku and make sure your Roku device and Android phone are connected to the same Wi-Fi network.

Step 3. On your Android phone, open a Google Cast-compatible app or the available Cast feature.

Step 4. Select the PigeonCast receiver on your Roku device from the list of available casting destinations.

Step 5. Follow any on-screen prompts to establish the connection and start casting your content to Roku.

With PigeonCast installed on Roku, you can use your existing streaming device as a compatible casting receiver without connecting an external Chromecast. The content you can cast depends on the sending app and supported casting mode.

Method 3. Cast to Roku TV from Supported Apps

You don't necessarily need an external Chromecast or another screen mirroring app to stream videos to Roku TV. Some popular apps, including YouTube and Netflix, support casting or controlling playback directly on compatible Roku devices.

Roku can use app-specific discovery and launch mechanisms, including DIAL, rather than acting as a universal Google Cast receiver.

Step 1. Make sure your Roku TV and phone are connected to the same Wi-Fi network.

Step 2. Install the supported streaming app on both your phone and Roku TV.

Step 3. Open the app on your Android phone or iPhone and choose the video you want to play.

Step 4. Tap the Cast icon in the app and select your Roku TV from the available devices.

Step 5. Once connected, the corresponding app should open on Roku and begin playing your selected content.

This method works well for supported streaming services, but it doesn't mirror your entire phone screen. Not every app with a Google Cast button supports Roku, so availability depends on the app and receiving device.

Method 4. Screen Mirror to Roku TV Without Chromecast

If you want to display your entire phone or computer screen, Roku also supports screen mirroring through Miracast on compatible Android and Windows devices, as well as AirPlay on supported Roku models.

This method is useful for sharing photos, presentations, websites, or apps without purchasing a Chromecast device.

Step 1. Enable Screen Mirroring on Roku TV

• Go to Settings > System > Screen mirroring.
• Set Screen mirroring mode to Prompt or Always allow, if these options are available.
• For Apple devices, open Settings > Apple AirPlay and HomeKit and make sure AirPlay is turned on.

Step 2. Connect Your Devices to the Same Network

• On Roku, go to Settings > Network > About to check the network connection.
• Connect your phone or computer to the same local network.
• If your router uses separate 2.4 GHz and 5 GHz networks, make sure the devices can communicate with each other.

Step 3. Start Screen Mirroring

Choose the option that matches your device:

• Android: On a Miracast-compatible phone, open Smart View, Wireless Display, or the equivalent screen mirroring feature, then select your Roku TV.
• Windows: Press Win + K to open the wireless display menu and select your Roku device.
• iPhone or Mac: Open Control Center > Screen Mirroring and select your AirPlay-compatible Roku TV.

Step 4. Confirm the Connection

Approve the connection on your Roku TV if prompted. Once connected, your device screen should appear on the television.

Step 5. Check Playback Quality

Play a short video to check picture quality and audio synchronization. If playback stutters, reduce network congestion, move closer to the router, or reconnect your devices.

Keep in mind that Google Pixel phones generally don't support Roku's native Miracast screen mirroring. If you're using a Pixel, a compatible Google Cast receiver or another supported casting solution may be necessary.

Chromecast vs. Screen Mirroring on Roku TV

Although Chromecast and screen mirroring can both display content on your Roku TV, they work differently. Choosing the right method depends on whether you want to stream a specific video, mirror your entire screen, or add Google Cast support without buying extra hardware.

Method	Extra Hardware	Best For
External Chromecast	Chromecast device	Using native Google Cast features
PigeonCast	None; install on Roku only	Google Cast from Android to Roku TV, Express, or Streaming Stick
Supported Apps	None	Streaming videos from YouTube and other Roku-compatible apps
Miracast / AirPlay	None on compatible Roku devices	Mirroring a compatible phone or computer screen

An external Chromecast provides native Google Cast functionality, while PigeonCast works as a Chromecast alternative by adding compatible casting capabilities to your existing Roku device. Supported apps let you stream selected content directly, whereas screen mirroring displays your device's screen on the TV in real time.

Troubleshooting Chromecast and Casting to Roku TV

When Roku casting still fails after basic setup, diagnose the problem by symptom rather than repeating every connection step. Device discovery, connection stability, and playback issues often have different causes.

If Roku TV Is Missing from the List

When your phone or computer can't find Roku TV, first check whether the receiver supports the casting method you're trying to use. Roku may appear in a supported app or Miracast menu but not in Chrome's standard Google Cast device list.

• Check compatibility: Make sure you're using a method supported by your sender and Roku device.
• Restart devices: Restart your router, Roku TV, and phone or computer to refresh local network connections.
• Disable network isolation: Check whether guest Wi-Fi or AP/client isolation is preventing devices from communicating.
• Try another connection path: If direct casting isn't available, use a compatible screen mirroring method or PigeonCast.

If the Connection Drops or Lagging Occurs

Short sessions, stuttering, or frequent disconnects are often related to Wi-Fi interference, network congestion, or device performance.

• Move closer to the router: Improve signal strength by keeping your devices within a reliable wireless range.
• Manage bandwidth: Pause heavy downloads, cloud syncing, or other high-bandwidth activity while casting.
• Keep your device active: Prevent your phone or computer from sleeping during initial connection setup.
• Reconnect: Stop the session, wait a few seconds, and establish a new connection if the stream becomes unstable.

If You See a Black Screen or Have No Audio

If your devices connect successfully but the content doesn't play correctly, the problem may involve the app, media format, audio output, or content protection.

• Reset the session: Stop casting completely and start a new session.
• Test another app: Try displaying a photo or playing an unprotected video to identify app-specific restrictions.
• Check audio output: Make sure sound isn't muted and the correct playback device is selected.
• Restart Roku: Use the Roku settings menu to perform a system restart if playback remains stuck.

Some streaming services use DRM protection that prevents certain content from appearing through screen mirroring, even when the connection itself works.

Final Words

Knowing how to Chromecast to Roku TV starts with choosing the right connection method. An external Chromecast provides native Google Cast support, while compatible Roku apps let you stream selected videos without extra hardware.

PigeonCast offers a convenient Chromecast alternative, especially for Roku Express and Streaming Stick owners. Just install it on your Roku device to receive supported Google Cast content without buying another streaming device. Miracast and AirPlay are also available for screen mirroring on compatible devices.

How to Chromecast to Roku TV FAQ

Why Can't I Cast Onto My Roku TV?

Your Roku TV may not appear because the casting method isn't compatible with its receiving features, even when both devices are connected to the same Wi-Fi network. Guest networks, router isolation, outdated software, or disabled screen mirroring settings can also prevent connections. First, check whether you're using a supported app, Google Cast receiver, Miracast, or AirPlay. Then restart your devices and verify their network settings.

How to Cast to Roku TV from Google Pixel?

Google Pixel phones use Google Cast rather than Miracast, so Roku's native screen mirroring may not detect them. One option is to install PigeonCast on your Roku device, which can act as a compatible Google Cast receiver without requiring another app on your Pixel. Connect both devices to the same Wi-Fi network, open a supported Cast feature or app on your Pixel, and select the PigeonCast receiver to connect.

How to Cast Chromebook to Roku TV Without Chromecast?

A Chromebook's built-in Cast feature normally looks for Google Cast-compatible receivers, so a standard Roku TV may not appear in the device list. You can install PigeonCast on Roku as an alternative receiver for supported Google Cast content or use a streaming app that supports Roku directly. For more connection methods and device-specific instructions, see our Chromebook-to-Roku casting guide.

Why Does Roku TV Show Up but Fail to Connect?

If your Roku TV appears in the device list but won't connect, the problem may be a timed-out permission prompt, unstable local network, or a mismatch between the sender's casting protocol and Roku's receiver. Check for connection requests on your TV, restart both devices, and make sure they can communicate on the same network. If the issue continues, try another compatible casting method.

Can You Use Chromecast with a Roku Streaming Stick?

You can't connect a Chromecast directly to a Roku Streaming Stick because both devices output video through HDMI. However, you can connect Chromecast to another HDMI port on your television and switch between them. If you prefer not to buy extra hardware, install PigeonCast directly on your Roku Streaming Stick to receive supported Google Cast content from Android devices, making it a practical Chromecast alternative.
