What is Chromecast?

Chromecast is a family of dongles for your TV, plugged into your TV’s HDMI port to add smart features to your TV, like streaming Netflix for example. The Chromecast connects to your home network and can then be controlled with your smartphone. This will allow you to open an entertainment app on your phone and, via Chromecast, play content on your TV.

Most importantly, you use the Google Cast protocol to get this content on your TV, so there must be support from the source you are using. Services like Netflix, Amazon Prime Video, YouTube, Chrome (browser), Android, and many others are compatible with Google Cast.

Google released the first Chromecast in 2013 and updated it in 2015 with Chromecast 2, and then again in 2018 with the third generation Chromecast. While they all support Full HD content, these Chromecast models gradually get faster, with stronger Wi-Fi for better connectivity.

In 2016, Google introduced the Chromecast Ultra, which works similarly to its predecessors but offers the ability to stream 4K. Chromecast Ultra also supports Ethernet and Wi-Fi, to ensure you get a good enough connection for the most demanding streams. Chromecast Ultra is still in use, as it is the device that Google Stadia uses on your TV.

How does Chromecast work?

The important thing to note about streaming is that it is not about casting content from your phone to the Chromecast dongle.

Chromecast then uses your connection to retrieve that broadcast in the best possible quality.

This means that if you connect the Chromecast Ultra to a 4K TV, for example, it will play 4K content that you can’t see on your phone.

However, if you’re mirroring your phone to a TV or viewing a website, you’re casting it directly from your phone or computer straight to Chromecast and the two of you need to stay in touch. This is the case if you wrap the screen of an Android device, a Chrome tab, or a Chromebook desktop.

You also need a compatible Android or iOS device with the latest version of the app, now called Google Home, installed, or you need a compatible Windows, Mac, or Chromebook computer with the latest version of the Chrome browser installed. The Google Home app is the same app you use to control other Google devices, such as the Nest Hub, and to set up smart home features for control from your phone.
