Installing the FuboTV app from the VIZIO Smart TV's app store (VIA or VIA+) is the first step in connecting FuboTV to your VIZIO TV using the 6-digit activation code. Open the FuboTV app on your VIZIO TV when it has been installed. A six-digit activation code will appear on the screen of the app. Visit fubo.tv/link9 on a different device, like your computer or smartphone. Select "Submit" or "Activate." After your VIZIO TV has refreshed, you will be instantly logged in and able to begin streaming. Â
