SmartCast is Vizio’s all-in-one smart TV platform, built directly into every modern Vizio television. It gives you instant access to dozens of streaming apps, a free live TV service called WatchFree+, voice control through Amazon Alexa and Google Assistant, and a mobile app that turns your smartphone into a full-featured remote. Whether you’re cutting the cord for the first time or upgrading from an older TV, SmartCast makes it easy to watch what you want, when you want — no extra hardware required.

​
What Is SmartCast?

SmartCast is more than just a way to open Netflix. It’s a complete entertainment ecosystem designed to unify all of your content in one place. Here’s what’s included:
  • Built-in App Store — Browse and install hundreds of streaming apps including Netflix, Hulu, Disney+, Amazon Prime Video, Max, Apple TV+, YouTube, Peacock, Paramount+, ESPN+, Pluto TV, and Tubi. New apps are added regularly, so your library keeps growing.
  • WatchFree+ — Vizio’s own free, ad-supported streaming service gives you access to hundreds of live TV channels and thousands of on-demand titles. No subscription, no sign-in required — just press play.
  • SmartCast Mobile App — Download the free SmartCast app for iOS or Android to use your phone as a wireless remote, browse content, and cast directly to your TV.
  • Chromecast Built-In — Every SmartCast TV includes Chromecast built-in, so you can cast from your phone, tablet, or laptop browser without any extra dongle or device.
  • Voice Control — Pair your TV with Amazon Alexa or Google Assistant to control playback, switch inputs, adjust volume, search for shows, and more using just your voice.
  • AirPlay 2 — On newer Vizio models, AirPlay 2 lets you mirror your iPhone, iPad, or Mac screen directly to your TV with no app required.
SmartCast is available on all Vizio Smart TVs manufactured after 2016. If you have an older Vizio TV, it may run VIZIO Internet Apps Plus (V.I.A. Plus) instead — the setup process is similar but the interface looks different.

Prerequisites for SmartCast

Before you dive in, make sure you have everything in place for a smooth setup experience.
  • TV Activation — New Vizio TVs must be activated before SmartCast features are fully available. Visit vizio.com/setup from any browser, enter your TV’s serial number, and follow the on-screen steps.
  • WiFi Connection — SmartCast requires a stable internet connection. A 5 GHz WiFi network is recommended for HD and 4K streaming. Connect your TV to your home WiFi during initial setup.
  • Vizio Account — Create a free Vizio account if you don’t have one already. You can register during activation or at any time through the Vizio website. Your account lets you manage your installed apps, link streaming services, and sync your SmartCast mobile app.
  • Vizio Remote — Your TV remote should have a V button or a dedicated SmartCast button. This is your shortcut to the SmartCast home screen. If your remote is missing, the SmartCast mobile app can serve as a full replacement.
If you haven’t activated your TV yet, head to vizio.com/setup before continuing. Activation unlocks all SmartCast features and links your TV to your Vizio account. Without it, certain apps and services may not function correctly.

Setting Up SmartCast

Follow these steps to get SmartCast up and running on your Vizio TV.
1

Activate Your TV at vizio.com/setup

On a phone, tablet, or computer, navigate to vizio.com/setup. Sign in to your Vizio account or create a new one. Enter the serial number printed on the back of your TV or shown in Menu → System → System Information. Follow the prompts to complete activation. This step registers your TV and ensures all SmartCast features are unlocked.
2

Connect Your TV to WiFi

Using your Vizio remote, press the Menu button and navigate to Network → Network Connection. Select your home WiFi network from the list and enter your password using the on-screen keyboard. Once connected, you’ll see a confirmation message. A solid WiFi connection is essential for streaming and app downloads.
3

Press the V or SmartCast Button

Press the V button (or the SmartCast button on newer remotes) on your Vizio remote. This takes you directly to the SmartCast home screen. If this is your first time, the TV may prompt you to sign in to your Vizio account — use the same credentials you created during activation.
4

Browse the SmartCast Home Screen

Take a moment to explore the SmartCast home screen. You’ll see a featured content banner at the top, a row of your installed apps, quick access to WatchFree+, and a “Continue Watching” section that tracks what you’ve been viewing. Use the directional buttons on your remote to scroll through the rows and select content.
5

Download the SmartCast Mobile App

On your smartphone, open the App Store (iOS) or Google Play Store (Android) and search for VIZIO SmartCast. Download and install the free app. Open it, sign in with your Vizio account, and make sure your phone is on the same WiFi network as your TV. The app will automatically detect your TV and connect.
6

Sign In with Your Vizio Account

On both your TV and the SmartCast app, sign in using your Vizio account email and password. This syncs your app preferences, installed apps, and viewing history across devices. If you forget your password, you can reset it from the sign-in screen on the Vizio website.

​
SmartCast Home Screen Overview

The SmartCast home screen is your central hub for everything on your Vizio TV. Understanding the layout helps you navigate quickly and find content without digging through menus.
  • Featured Content Banner — The large image at the top of the screen highlights trending shows, new releases, and promoted content from your installed apps. Press OK on the remote to jump straight in.
  • Apps Row — Immediately below the banner, you’ll find your installed streaming apps displayed as tiles. Scroll right to see all of them or select App Store at the end of the row to browse new apps.
  • WatchFree+ Row — Vizio’s free streaming service gets its own dedicated row on the home screen. You can browse live channels and on-demand content without leaving SmartCast.
  • Continue Watching — SmartCast tracks your viewing history across supported apps and displays your in-progress titles here. Pick up right where you left off.
  • Inputs — At the bottom of the home screen, you’ll find quick shortcuts to switch to connected devices like your cable box, gaming console, or Blu-ray player.
To rearrange or customize the home screen, press the Menu button and look for display or home screen settings. You can prioritize the apps and rows you use most often.

​
SmartCast Mobile App

The SmartCast mobile app is one of the most useful tools Vizio provides, and it’s completely free. Available for both iOS and Android, the app transforms your smartphone into a powerful TV remote with added features you won’t find on the physical remote. Downloading the App Search for VIZIO SmartCast in the Apple App Store or Google Play Store. Install the app and sign in with your Vizio account. Make sure your phone is connected to the same WiFi network as your TV — this is how the app discovers and communicates with your television. Using the App as a Remote Once connected, the app displays a full remote control layout on your screen. You can navigate the SmartCast home screen, adjust volume, change inputs, and control playback. The app’s virtual keyboard makes entering passwords and search queries far easier than using the on-screen TV keyboard with a standard remote. Casting Content The SmartCast app also supports casting, allowing you to send content from your phone directly to your TV. Browse content in the app, tap the Cast icon, and select your Vizio TV. Playback immediately moves to the big screen while your phone acts as a remote controller.
The SmartCast mobile app is a complete replacement for your physical Vizio remote. If you’ve misplaced the remote or the batteries have died, download the app immediately and you’ll have full TV control restored within minutes.

Voice Control with SmartCast

Vizio SmartCast supports voice control through both Amazon Alexa and Google Assistant, giving you hands-free control over your TV. Setting Up Amazon Alexa If you have an Amazon Echo or Alexa-enabled device, you can link it to your Vizio TV through the Alexa app. Open the Alexa app on your phone, go to Skills & Games, and search for Vizio SmartCast. Enable the skill and sign in with your Vizio account when prompted. Once linked, you can say things like “Alexa, turn on the TV”, “Alexa, play Netflix on the living room TV”, or “Alexa, turn the volume up.” Setting Up Google Assistant If you prefer Google Assistant, open the Google Home app, tap + to add a device, and select Works with Google. Search for Vizio SmartCast and sign in with your Vizio account. Once connected, use commands like “Hey Google, play YouTube on my Vizio TV” or “Hey Google, pause the TV.” Built-In Voice on the Remote Some Vizio remotes include a built-in microphone button. Press and hold the microphone button, then speak your command. You can search for shows, open apps, adjust volume, and switch inputs — all without typing a single character.
