How to Use Chromecast: Beginners Guide

If you want to broadcast video content to multiple displays throughout your home, the Google Chromecast is one of the best and cheapest choices. However, if you’re unfamiliar with the technology, you may be curious about how to use Chromecast.

We’ll cover how to use Chromecast on your TV, PC, Mac, iPhone, and Android in this article. Additionally, we’ll address a few frequently asked questions, such as how to use Chromecast without internet or Wi-Fi.

Which Devices Supports Chromecast Streaming?

Although the majority of Google’s support documentation for Chromecast focuses on connecting the dongle to your television, the list of supported devices is far longer.

A Chromecast requires two connections to function properly: a power supply and an HDMI port.

HDMI is compatible with any screen that supports HDMI input. That includes, but is not limited to, freestanding monitors, projectors, and other comparable equipment.

Chromecast dongles cannot be used to view cast content on an Android or iOS device, a laptop, or any other device with an output-only port.

Additionally, if you’re using a Chromecast Ultra, a 4K-capable television and a high-speed internet connection are required.

Connect Your Chromecast to the Internet via Wi-Fi

If you’re using a Chromecast at home or in the workplace, the logical first step is to connect the device to your house or business’s Wi-Fi network.

To connect your Chromecast to Wi-Fi, you must ensure that the device you are using to configure your dongle (such as an Android or iPhone) is connected to the same Wi-Fi network as the one to which you eventually wish to connect your Chromecast.

Note: A Chromecast cannot be configured via a computer.

To get started, download the free Google Home app from the app store on your smartphone. Navigate to Add > Set up device > New device within the app and follow the on-screen steps.

How to Use Chromecast on a PC

There are several methods for connecting a Chromecast to a PC. All of the methods need the use of the Google Chrome web browser.

Chrome allows you to stream content from a single tab, your full desktop, or a file on your laptop.

To begin, open Chrome and navigate to More > Cast. A new window will open, displaying all of your network’s Chromecast devices (video and audio). To pick a device, click on it. Select Sources to specify whether a tab, a file, or your desktop should be cast.

If you choose to stream a single Chrome tab or a file, you can continue using other Chrome tabs and the rest of your computer without interfering with the casting or disclosing the contents of your screen to those watching the casted output.

The only stipulation is that you keep Chrome open and running in the background while using other programs.

By comparison, if you choose to cast your complete desktop, everything that is displayed on your computer’s screen will be displayed on the casting destination as well. Before selecting this option, ensure that your computer does not contain any sensitive information that you do not like to make public.

Once again, you must leave Chrome running in order to continue casting.

Chromecast devices are only compatible with Windows 7 or later.

How to Use Chromecast on a Mac

If you want to stream a video or your full desktop to Chromecast, the method is identical to that on a Windows PC.

For a quick reference, consider the following steps:

  • Navigate to Google Chrome.
  • To begin, navigate to More (three vertical dots) > Cast.
  • Choose a Chromecast destination.
  • To cast a file, a tab, or your entire screen, click on Sources.
  • Allow Chrome to run throughout the casting process.

How to Use Chromecast on Android

When it comes to casting material from their cellphone to a TV screen, Android users have slightly more options than iOS users.

This is due to Android’s unique ability to cast its full screen in addition to the ability of individual apps to cast.

The ability to cast your entire screen has a number of advantages. Notably, it enables users to cast multimedia from apps that do not natively support Chromecast.

To use Chromecast with your Android device, open the Settings app, navigate to Connected devices > Connection Preferences > Cast, and choose your Chromecast device from the list. Bear in mind that your phone and Chromecast must be connected to the same Wi-Fi network.

Certain applications, such as YouTube, include a built-in casting button. It resembles a little television screen. When you tap the button, the video you’re watching is immediately cast to your Chromecast.

The remainder of your phone’s UI (including other apps and notifications) will not be broadcast, providing you with increased privacy if you’re casting in a public space.

How to Use Chromecast on an iPhone

iPhone users can cast content from their device to a Chromecast natively only if the app they’re using supports the feature. Unless you utilize a third-party tool like Replica, there is no way to cast your complete screen.

If the app you’re using supports Chromecast, a little button like a television screen will appear somewhere on the app’s home screen or menu. To view a list of Chromecast devices on your network, tap the symbol.

How to Use Chromecast in the Absence of Wi-Fi

Without a Wi-Fi connection, you can use your Chromecast if you have an Android device.

The procedure for utilizing a Chromecast without Wi-Fi is nearly identical to that for casting over Wi-Fi. To cast material from your entire screen or an app, follow the preceding procedures.

Your Android device will search for Chromecasts that are not connected to a network in the area. When the Chromecast you want to connect to is displayed, tap on its name. On the television screen, a four-digit PIN will appear. Enter it into your Android when requested to complete the connection.

Note: If you have an iPhone and frequently need to cast without Wi-Fi, the cheapest and possibly best approach is to purchase a cheap mobile router.


We’ve covered how to use Chromecast in this post, which should be sufficient to get you started with your device and supported apps.

Of course, a Chromecast is capable of much more. For instance, you might begin by using it to add another monitor to your computer.
