Before you can start wirelessly streaming media straight from the apps on your phone to your TV, first you’ll need to know how to set up Chromecast.

How to set up your Chromecast
Plug in the Chromecast to a power source and an HDMI port on your TV.
Be sure that you’ve got the Google Home app downloaded onto your phone or tablet (iOS is also supported).
Connect your phone or tablet to the Wi-Fi network you want the Chromecast to be set up on.
Open the Google Home app on your device.
You should see an option for Set up new device but if you don’t see that just tap the Add icon (+).
Tap Set up device
Tap Set up new devices in your home.
Next, you’ll be asked to choose a home, which is how Google organizes all the smart products connected to your Google account.
Tap the device you want to set up. It will be labeled as a Chromecast or Chromecast Ultra depending on the device you’re setting up.
Confirm that the four-digit code on the app matches the code on your TV.
Choose whether to opt-in to send your device stats and crash reports back to Google.
Set your Chromecast’s room location. This is especially important if you plan to set up multiple Chromecasts in your home.
Tap your Wi-Fi network. You won’t have to input any login details as long as your phone is already connected to it.
Other things you might need to know
Now that you know the basics for how to set up a Chromecast, here are some other minor setup tips worth noting:
- Many TVs have a USB port on the back and you might be tempted to cut down cord clutter and just plug your Chromecast into that for power. Even if you test it out and find that it supplies enough power for your Chromecast, it’s not recommended because TV USB ports are notoriously unreliable and also your Chromecast will need to reboot every time you turn the TV on.
- The Chromecast Ultra features an Ethernet port built into the power supply that you can use in lieu of a wireless connection. A wired connection might not be feasible depending on the location of your modem/router but it could be a better setup if you want to avoid buffering or stuttering video while streaming in 4K.
- The Chromecast with Google TV has no ethernet port but charges via USB-C. You can connect a USB-C hub to your Chromecast with Google TV and plug in an ethernet cord from your router to the hub. This will not only give you a more consistent wired internet connection, but also lets you use power over ethernet (PoE), sparing you a power outlet.
- Chromecast 3rd Gen owners should check out our list of the best ethernet adapters for Chromecast, which will work specifically with its micro-USB power cord.
- Setting the proper room details for your Chromecast is especially important if you want to use Google Assistant to call up content since you’ll need to specify the room when making your voice command. For example, you’d say “OK Google, play The Office on bedroom Chromecast”.

Streaming on a budget
If you’re looking for the cheapest possible way to start streaming to your TV, the 3rd-gen Chromecast fits the bill. It’s cheaper than the Chromecast with Google TV, making it appealing for anyone who doesn’t stream 4K or wants to connect a secondary TV.
