The VIZIO SmartCast app transforms your phone or tablet into a full remote control and content discovery hub for your VIZIO Smart TV. Available for free on both iOS and Android, SmartCast lets you browse apps, cast media, and adjust settings — all from the palm of your hand. To pair successfully, both your TV and mobile device must be connected to the same Wi-Fi network.

​
Prerequisites

Before getting started, make sure you have the following:
  • A VIZIO Smart TV connected to Wi-Fi
  • An iOS 13+ or Android 8.0+ mobile device
  • A free VIZIO account — register at vizio.com/setup if you don’t have one

​

App Store (iPhone/iPad)

Search ‘VIZIO SmartCast’ in the App Store to find and install the app on your iPhone or iPad.

Pair the App with Your TV

1

Open SmartCast App

Launch the SmartCast app on your phone and sign in with your VIZIO account credentials.
2

Ensure Same Network

Make sure your phone and your VIZIO TV are both connected to the same Wi-Fi network. Pairing will not work across different networks.
3

Tap Devices

In the app, tap the Devices icon at the bottom of the screen. Your VIZIO TV should appear automatically in the list of available devices.
4

Select Your TV

Tap your TV’s name to begin pairing. A pairing code may appear on your TV screen — enter it in the app when prompted to confirm the connection.
5

Start Controlling

Once paired, use the app as a full remote control, browse SmartCast content, and cast photos, videos, or music directly from your phone to the TV.

Key SmartCast Features

  • Full remote control — including voice commands via Google Assistant or Alexa
  • Cast content — stream photos, videos, and music from your phone to the TV
  • Browse and launch apps — access streaming services like Netflix, Disney+, Hulu, and more
  • Adjust picture and sound settings — fine-tune your viewing experience directly from your phone
  • Manage multiple TVs — set up and control multiple VIZIO TVs from a single app

​
Troubleshooting

Ensure both your phone and TV are connected to the same Wi-Fi network. Try restarting the SmartCast app and power-cycling your TV. Also confirm your TV has an active internet connection by checking its network settings.
Manually trigger a new pairing code from your TV by navigating to Menu > SmartCast > Pair Device. The code will then display on screen for you to enter in the app.
Battery optimization settings on your phone may be causing the app to close in the background. Go to your phone’s settings and disable battery optimization for the VIZIO SmartCast app to maintain a stable connection.
Casting requires the app to have permission to access your local network. Open your phone’s settings, find the SmartCast app under app permissions, and ensure Local Network access is enabled.
Use voice commands through the SmartCast app — say “Hey Google” or “Alexa” to control your TV completely hands-free.
