Chromecast does not work directly with Roku TVs

You cannot cast from a Chromecast device to a Roku TV. The two systems use different casting protocols — Chromecast uses Google Cast, while Roku uses its own proprietary system — and they do not communicate with each other. If you own a Roku TV and want to cast content to it, you need to use Roku's casting method instead, or use a different device altogether.

This limitation applies whether your Roku TV is a newer model or an older one. The incompatibility is fundamental to how the two platforms work, not a software issue that an update could fix.

Key Takeaways

  • Chromecast and Roku use different casting standards and cannot communicate, so you cannot cast from a Chromecast device to a Roku TV.
  • Roku TVs have built-in casting that works with phones and tablets running the Roku app, which is the native way to cast to your TV.
  • You can use AirPlay on some newer Roku TVs if you own an Apple device, but this is separate from Chromecast.
  • If you want Chromecast functionality, you would need to connect a separate Chromecast device to your Roku TV via HDMI, treating the Roku as a regular monitor.

How Roku's built-in casting works instead

Roku TVs come with their own casting system built in. You can cast to your Roku TV using the Roku app on your Android phone or tablet, or the Roku app on an iPhone or iPad. The app lets you send photos, music, and screen mirroring directly to the TV without needing any external hardware.

To cast using the Roku app, open the app on your phone, tap the Cast icon, select your Roku TV from the list, and choose what you want to send. This works over your home Wi-Fi network. Many streaming apps like Netflix, YouTube, and Spotify also have built-in Roku support, so you can cast from those apps directly without using the Roku app as a middleman.

Using AirPlay if you have Apple devices

Some newer Roku TVs support AirPlay, Apple's casting standard. If your Roku TV has AirPlay built in, you can cast from an iPhone, iPad, or Mac to your TV using the same method you would use with an Apple TV. Check your Roku TV's specifications or settings menu to see if AirPlay is available on your model.

AirPlay is not the same as Chromecast, but it serves the same purpose — letting you send content from your device to your TV wirelessly. If you own both Apple devices and a Roku TV with AirPlay support, this is your best option for wireless casting.

Connecting a separate Chromecast device to your Roku TV

If you already own a Chromecast device and want to use it with your Roku TV, you can plug the Chromecast into an available HDMI port on the TV. The Chromecast will then work exactly as it would with any other TV — you can cast to it from your phone, tablet, or computer using Google Cast.

The Roku TV itself will not be involved in the casting process. From the TV's perspective, the Chromecast is just another HDMI input, like a cable box or gaming console. You will need to switch your TV to that HDMI input to see what you are casting. This approach works but adds an extra device to your setup.

Why the two systems do not work together

Chromecast and Roku developed their casting systems independently, and neither company has built support for the other's standard into their products. Google designed Chromecast around its own Google Cast protocol, while Roku built its system around its own technology. Even though both do the same job — sending video and audio from a phone to a TV — they speak different languages and cannot understand each other's commands.

This is not unique to Roku and Chromecast. Amazon Fire TVs use their own casting system, and Apple TVs use AirPlay. Each major TV platform has chosen its own casting standard, which means you generally need to match your casting device to your TV brand.

Alternatives if you need Chromecast support

If casting from Chromecast is important to you and you are unhappy with Roku's casting options, you have a few paths forward. You can use the Roku app and Roku's native casting instead, which works well for most common tasks. You can connect a separate Chromecast device via HDMI if you want Google Cast specifically. Or, if you are shopping for a new TV, you can choose a TV brand that supports Google Cast natively, such as some Sony, LG, or TCL models.

Many Android phones and tablets can also cast to Roku TVs directly through the Roku app, so if you use Android devices, you already have a casting solution that works with your TV.

Frequently Asked Questions

Does Roku TV have any Google Cast support?

No. Roku TVs do not support Google Cast or Chromecast. They use Roku's own casting system, which is separate and incompatible. If you need Google Cast, you must use a separate Chromecast device connected via HDMI.

Can I use my phone to cast to a Roku TV?

Yes, if you have the Roku app installed on your Android or iOS phone. Open the app, tap the Cast icon, select your TV, and choose what to send. Many streaming apps like Netflix and YouTube also have built-in Roku support for direct casting.

What if I plug a Chromecast into my Roku TV's HDMI port?

The Chromecast will work normally. Switch your TV to that HDMI input, and you can cast to the Chromecast as you would with any other TV. The Roku TV itself is not involved — it is just providing the display and power.

Do all Roku TVs support AirPlay?

No, only newer Roku TV models have AirPlay built in. Check your TV's settings or the product specifications to see if yours supports it. If it does, you can cast from iPhones, iPads, and Macs without needing the Roku app.

Is there a way to make Chromecast and Roku work together?

No. The two systems are fundamentally incompatible and do not communicate. Your options are to use Roku's native casting, connect a separate Chromecast device via HDMI, or switch to a TV brand that supports Google Cast natively.
