Read below to learn everything you’ll need to get started.


  • You can use Chromecast to cast content from your mobile device, tablet, or computer with one button

How to Set Up a Chromecast for your TV

First, you’ll need a Google account and access to a secure WiFi connection. Next:

  1. Connect your Chromecast device to your television’s HDMI port
  2. Connect the USB power cable to your Chromecast device
  3. Connect the USB power cable into the power adapter and connect it to an outlet
  4. Download the Google Home app from the Google Play site on your device, tablet, or desktop
  5. Go to the Chromecast website and follow the short guide to install and set up Chromecast

You should now see the Chromecast welcome screen on your television. Write down or remember the Chromecast device number displayed on the bottom of the screen.

  1. Make sure Bluetooth is active on your device and open the Google Home app
  2. Press “Add” to add your Chromecast device and choose “home” or add your own with the preferred name
  3. Wait for the Google Home app to display all connected Bluetooth devices and choose the device with the number you saw on the welcome screen
  4. A confirmation number will appear on your television and your mobile device in the Google Home app. Press “confirm” on your mobile device.
  5. Choose your WiFi connection when prompted by the app. Make sure it’s the same secure connection your mobile device uses.
  6. Your television should now display your chosen Chromecast device’s name, with the current time on the bottom right of the screen. This can also be a great time to connect your bluetooth speakers to tv.

You’re now ready to start casting content from your mobile device. Casting content to your television is now as simple as navigating to the desired site on your Chromecast-connected mobile device, tablet, laptop, or desktop computer, pressing the “cast” button in your internet browser, and selecting your television at the prompt. Also, you can connect soundbar to tv for better audio performance when streaming content.

Remember to only use the AC adapter that came with your Chromecast device- using another can potentially damage your device.
