What Can a Chromecast Do? Full Guide

Updated 14 November 2026 · Standard formula, shown below

A Chromecast is a small media streaming device that plugs into your TV’s HDMI port, letting you cast videos, music, games, and more from your phone, tablet, or computer directly to the big screen. It turns any modern TV into a smart TV, giving you access to thousands of apps and services without needing a separate streaming box or a new television.

Background: What Is Chromecast?

Chromecast was introduced by Google in 2013 as a budget-friendly way to stream content to a TV. Unlike traditional streaming devices like Roku or Apple TV, which have their own remote and on-screen interface, Chromecast relies on your existing devices (phone, tablet, or laptop) as the remote and the source of content. The Chromecast itself is a small dongle that connects to your TV’s HDMI port and to your Wi-Fi network. It runs a stripped-down version of Google’s Cast platform, which receives streaming requests from your devices and pulls the content directly from the internet, so your phone isn’t constantly streaming and draining its battery.

How Chromecast Works

The core technology behind Chromecast is Google Cast, a protocol that allows apps on your phone or computer to send a URL or media stream to the Chromecast device. When you tap the Cast button in a supported app (like YouTube or Netflix), your device sends a command to the Chromecast, telling it to load a specific video or audio stream. The Chromecast then connects directly to the streaming service’s servers and plays the content, while your phone acts as a remote control. This means you can use your phone for other tasks while the video continues playing, and the Chromecast handles the heavy lifting of decoding and displaying the content.

To set up a Chromecast, you plug it into your TV’s HDMI port, connect it to power (via USB or an AC adapter), and then use the Google Home app on your phone to connect it to your Wi-Fi network. The setup process takes just a few minutes, and once done, you can start casting from any compatible app.

What Can You Do With a Chromecast?

Chromecast is far more versatile than just streaming Netflix. Here are the main things you can do:

Stream video from hundreds of apps – Netflix, YouTube, Disney+, Hulu, Prime Video, HBO Max, and many more all support Chromecast. You can cast movies, TV shows, and even live TV from services like YouTube TV.
Listen to music and podcasts – Spotify, Apple Music, Pandora, and podcast apps like Pocket Casts can cast audio to your TV or a connected soundbar. You can also cast from your phone’s browser to play any audio file.
Mirror your phone or computer screen – With the Google Home app (or built-in screen casting on Android), you can mirror your entire phone screen to the TV, which is useful for showing photos, presentations, or browsing the web. On a computer, you can cast a Chrome tab or your entire desktop to the TV.
Play games – Many casual games, like trivia games or party games, support casting to the TV. You can also use your phone as a controller while the game displays on the big screen.
Use Google Assistant – On Chromecast with Google TV (the latest version), you get a remote with a Google Assistant button. You can ask it to play specific shows, control volume, or even control smart home devices like lights and thermostats.
Display photos and art – In Ambient Mode, your Chromecast can display a slideshow of your Google Photos albums or curated artwork when idle, turning your TV into a digital picture frame.
Cast from your browser – The Chrome browser on a computer can cast any tab, which is handy for showing a website, a video that isn’t in a casting app, or a presentation to a room.

Chromecast vs. Chromecast with Google TV

There are two main types of Chromecast devices: the traditional Chromecast (often called Chromecast 3rd Gen or Chromecast Ultra) and the newer Chromecast with Google TV (HD and 4K). The traditional Chromecast has no remote and no on-screen interface; you must use your phone to cast content. The Chromecast with Google TV, on the other hand, includes a remote and runs the full Google TV operating system, which has its own apps, home screen, and search. This means you can use it like a standard streaming box, without needing a phone. The Google TV version also supports 4K HDR streaming and Dolby Vision on the 4K model, while the HD version is limited to 1080p.

Which one is better? It depends on your preference. If you’re comfortable using your phone as a remote and want the cheapest option, the traditional Chromecast is fine. If you prefer a traditional remote and a more familiar TV interface, the Chromecast with Google TV is worth the extra cost.

How to Choose the Right Chromecast

When picking a Chromecast, consider the following:

TV resolution – If you have a 4K TV, you’ll want the Chromecast with Google TV 4K or the Chromecast Ultra (if you can find it) to get the best picture. For 1080p TVs, the standard Chromecast or HD version is sufficient.
Remote or no remote – Decide if you want a physical remote. The Google TV versions include one; the classic Chromecast does not.
Smart home integration – If you want to use Google Assistant to control your TV and smart home, the Google TV version is better because it has a built-in microphone on the remote.
Budget – The classic Chromecast is usually cheaper than the Google TV versions. However, prices vary, and sales are common.

Common Problems and Solutions

Like any tech device, Chromecast can run into issues. Here are a few common ones and how to fix them:

Chromecast not showing up in apps – Make sure your phone and Chromecast are on the same Wi-Fi network. Also, check that the Chromecast is powered on and the TV is on the correct HDMI input. Restarting the Chromecast (unplug it for 10 seconds) often helps.
Buffering or poor video quality – This is usually a Wi-Fi issue. Move your router closer to the Chromecast, or try a Wi-Fi extender. Also, close bandwidth-heavy apps on other devices.
Screen mirroring not working – On Android, use the Google Home app to cast your screen. On iOS, screen mirroring is not supported; you can only cast from apps that have the Cast button.
Audio out of sync – Try restarting the Chromecast and your TV. Sometimes adjusting the audio delay in the TV settings helps.

Cost and Value

Chromecast devices are among the most affordable streaming options. The classic Chromecast (3rd Gen) typically retails for around $30, while the Chromecast with Google TV HD is about $30 and the 4K version is around $50. There are no monthly fees for using Chromecast itself; you only pay for the streaming services you subscribe to (like Netflix or Hulu). Compare that to a smart TV, which might cost hundreds more, or a streaming box like Apple TV 4K, which is usually $150+. Chromecast is a budget-friendly way to upgrade an older TV.

Safety and Privacy

Chromecast is generally safe to use, but there are a few things to keep in mind. Since it connects to your Wi-Fi, anyone on the same network can potentially cast to it if you haven’t enabled guest mode or a PIN. To prevent unwanted casting, you can set a PIN in the Google Home app for guest casting. Also, be aware that Google collects some usage data to improve its services; you can review and manage your privacy settings in your Google account. When casting, your device sends the URL of the content to the Chromecast, but the actual streaming is done by the Chromecast, so your phone isn’t exposed to the content’s servers.

Alternatives to Chromecast

If Chromecast doesn’t suit your needs, there are several alternatives:

Amazon Fire TV Stick – Similar price range, but with its own remote and interface, and it supports Amazon’s Alexa voice assistant.
Roku Streaming Stick – Known for its simple interface and wide app support, with a remote and no phone required.
Apple TV 4K – More expensive, but integrates seamlessly with Apple devices and offers a polished experience.
Smart TVs – Many modern TVs have built-in streaming apps, so you might not need a separate device at all.
