You can cast your phone to your Vizio TV using two built-in wireless methods: Chromecast built-in for streaming from apps on both Android and iPhone, and AirPlay 2 for screen mirroring from Apple devices. Most Vizio SmartCast TVs include Chromecast built-in, meaning a separate Chromecast dongle is not needed, and newer models also support AirPlay 2, so an Apple TV device is not required.
First, connect both devices to the same Wi-Fi
Before you can cast anything, your phone and Vizio TV must be connected to the same Wi-Fi network. This is the essential prerequisite for all wireless casting.
Cast from an app using Chromecast built-in
This is the most common way to cast, and it works for both Android and iOS devices. Open a compatible streaming app on your phone, such as YouTube or Netflix. Tap the Cast icon (a rectangle with a Wi-Fi symbol). From the list of available devices, select your Vizio TV. The content will begin playing on your TV while your phone acts as a remote.
Mirror your Android screen with the Cast tile
To mirror your Android phone's entire screen, swipe down twice from the top of the screen to open Quick Settings. Tap the "Cast" tile (it may be labeled "Smart View," "Screen Mirroring," or "Wireless Display" depending on your phone brand). Select your Vizio TV from the list. Your phone's screen will now appear on the TV, showing everything including apps, photos, and games.
Mirror your iPhone screen with AirPlay 2
- First, ensure AirPlay is enabled on your Vizio TV by going to Settings > Apple AirPlay and setting the toggle to "On".
- On your iPhone, swipe down from the top-right corner (or up from the bottom for older models) to open Control Center.
- Tap "Screen Mirroring" and select your Vizio TV from the list.
- If prompted, enter the four-digit passcode displayed on your Vizio TV into your iPhone to complete the connection.
Your iPhone's screen will now be mirrored on your Vizio TV, allowing you to share photos, videos, or any app on the big screen.
Troubleshooting: why is my phone not casting to my Vizio TV?
Common issues preventing casting include the phone and TV being on different Wi-Fi bands (e.g., 2.4 GHz vs. 5 GHz), guest networks, or router settings like "AP isolation" or "client isolation" being enabled. Ensure your Vizio TV's firmware and the casting app on your phone are up to date to avoid compatibility issues. Restarting both your Vizio TV and your phone, as well as your Wi-Fi router, can resolve temporary connection problems.
Use a wired HDMI adapter as a fallback
If wireless casting is not possible, you can use a wired USB-C to HDMI adapter (for Android) or a Lightning to HDMI adapter (for iPhone) to connect your phone directly to an HDMI port on your Vizio TV. This provides a reliable alternative when wireless methods fail, and is the most dependable way to achieve casting your phone to a TV. If your Vizio TV does not support casting, you can use external casting devices, such as Google Chromecast or Roku Streaming Stick, which plug into your TV's HDMI port.
Frequently Asked Questions
Do I need a separate Chromecast device for my Vizio TV?
No. Most Vizio SmartCast TVs have Chromecast built-in, so you do not need to buy a separate Chromecast dongle.
Can I use the Vizio SmartCast mobile app to cast?
The Vizio SmartCast mobile app acts as a remote control and content launcher, but AirPlay and Chromecast built-in communicate directly with the TV for casting and mirroring. You do not need the app to cast. The Vizio SmartCast mobile app is available for Android 4.4+ and iOS 8.0+.
What if my Vizio TV doesn't support AirPlay?
If your Vizio TV does not support AirPlay 2, you can still cast using Chromecast built-in from compatible apps on your iPhone, or use a wired Lightning to HDMI adapter as a fallback.
Why does my phone keep disconnecting from the TV?
This is often caused by Wi-Fi interference or the devices being on different network bands. Ensure both devices are on the same Wi-Fi network (preferably the 5 GHz band if available) and that your router does not have AP/client isolation enabled. To verify if your Vizio TV supports casting, you can check the user manual or visit the Vizio website for detailed information on your specific TV model, looking for features like 'SmartCast' or 'Screen Mirroring'.
