How to Cast to Vizio TV from iPhone or Android

Q: How do I cast to a Vizio TV from my Android phone?

Install CastBrowser on your Android phone and connect it to the same Wi-Fi as the Vizio TV. Open a compatible website in CastBrowser, start the video so it is detected, tap the cast icon, and pick your Vizio SmartCast TV. On models with Chromecast built-in, CastBrowser sends the stream over Google Cast and the TV plays it directly.

Q: How do I cast to a Vizio TV from my iPhone?

Install CastBrowser on your iPhone and join the same Wi-Fi as the Vizio TV. Open a compatible website, start the video, tap cast, and choose your Vizio. On Vizio SmartCast TVs with Chromecast built-in, CastBrowser casts over Google Cast directly from the iPhone — no Apple TV required. Newer Vizio SmartCast TVs also support AirPlay 2, which iPhone users can use as an alternative.

Q: Can I cast to a Vizio TV without Chromecast?

Yes. If your Vizio model does not have Chromecast built-in, CastBrowser can fall back to DLNA on models that support it, or to the CastBrowser Web Receiver opened in the Vizio web browser where available. Both paths require your phone and TV to be on the same local network. Support varies by Vizio model, so not every method works on every TV.

Q: Why won't my Vizio TV show up when I try to cast?

The most common cause is that your phone and Vizio TV are on different or isolated networks — for example an isolated guest network, separate subnet, or VLAN. A device on a router's 2.4 GHz band can normally reach one on 5 GHz of the same router, so the band itself is rarely the issue. Confirm both devices can communicate on the same local network, disable any VPN on your phone, and check your router for AP or client isolation, which blocks devices from finding each other even on the same Wi-Fi. Restarting the TV and pulling to refresh the device list in CastBrowser also helps.

Cast to Vizio in 30 seconds

On a Vizio SmartCast TV with Chromecast built-in, the TV is already a Google Cast receiver. CastBrowser detects the web video on your phone and hands the stream to the TV.

Install CastBrowser (free) on your Android phone or iPhone.
Connect your phone and Vizio TV to the same Wi-Fi network.
Open a compatible website in CastBrowser and start the video.
Tap the cast icon and pick your Vizio SmartCast TV.
The Vizio plays the stream — your phone stays the remote.

Note: not every Vizio model supports every protocol. Chromecast built-in is common on SmartCast TVs; AirPlay 2, DLNA, and Web Receiver availability depends on the model.

How Vizio Casting Works: SmartCast and Chromecast Built-In

Vizio's smart TV platform is called SmartCast, and most SmartCast TVs include Chromecast built-in. That means the TV is a Google Cast receiver out of the box — there is nothing to plug in. When you cast a compatible video, your phone sends the stream to the TV and the TV plays it directly, while your phone becomes the remote.

This is fundamentally different from screen mirroring. Casting sends the actual video stream to the TV at its own quality, so your phone's battery is spared and your notifications never appear on screen. CastBrowser is a casting app, not a screen-mirroring app.

A few caveats: support depends on the model and software version. Most current SmartCast TVs include Chromecast built-in; newer SmartCast models also add AirPlay 2; and DLNA support is inconsistent across Vizio's lineup. The sections below cover each path so you can use whichever your TV actually supports.

How to Cast to Vizio TV from Android

Android is the most direct path because Google Cast is native to the platform. On a Vizio SmartCast TV with Chromecast built-in:

Install CastBrowser from the Google Play Store.
Connect your Android phone and Vizio TV to the same Wi-Fi network.
Open a compatible website in CastBrowser and start the video so it is detected.
Tap the cast icon and select your Vizio SmartCast TV from the list.
The video plays on the TV over Google Cast. Use your phone to play, pause, and seek.

Android users also get background casting — once the stream is playing, you can lock the screen or switch apps and it keeps going. For broader Android tips, see casting from Android to TV.

How to Cast to Vizio TV from iPhone

iPhone users have two routes on a Vizio SmartCast TV: Google Cast through CastBrowser, or AirPlay 2 on models that support it.

Install CastBrowser from the Apple App Store.
Connect your iPhone and Vizio TV to the same Wi-Fi network.
Open a compatible website in CastBrowser and start the video.
Tap the cast icon and choose your Vizio SmartCast TV.
The video plays on the TV over Google Cast — no Apple TV needed.

If your Vizio model supports AirPlay 2, you can also AirPlay compatible content directly from iOS. CastBrowser's advantage is that the same app also reaches Chromecast, Roku, Fire TV, and DLNA TVs, so you are not limited to AirPlay-only devices. More detail is in the cast from iPhone to TV guide.

Casting to a Vizio TV Without Chromecast Built-In

Older or entry-level Vizio sets may not include Chromecast built-in. In that case you have two fallbacks, both of which depend on your specific model:

DLNA, where supported: Some Vizio TVs accept media over DLNA. CastBrowser can use DLNA to send a compatible stream or local file, but Vizio's DLNA support is inconsistent across the lineup, so this does not work on every model.
Web Receiver: If your Vizio has a usable web browser, open the CastBrowser Web Receiver on the TV and cast to it from your phone. This only works when the phone and TV can reach each other on the same local network.

Whichever path your TV supports, remember that detection of a stream is not a guarantee of playback. The receiver still has to support the video's format and codecs, and DRM-protected content cannot be cast.

Supported Video Formats

CastBrowser detects videos in over 20 formats, including adaptive streams. Whether a given file plays still depends on what your Vizio model can decode.

Troubleshooting Vizio Casting

Vizio TV not showing up in the device list?

Check Wi-Fi: Confirm your phone and Vizio TV can communicate on the same local network and are not separated by an isolated guest network, subnet, or VLAN. A router's 2.4 GHz and 5 GHz bands can normally reach each other, so the band itself is rarely the problem.
Disable VPN: A VPN on your phone blocks local network discovery. Turn it off and try again.
Check router isolation: "AP isolation" or "client isolation" stops devices from seeing each other. Disable it in your router settings.
Restart the TV: Power-cycle the Vizio and pull to refresh the device list in CastBrowser.
Confirm SmartCast: Very old or non-SmartCast Vizio TVs may not have Chromecast built-in. Use the DLNA or Web Receiver fallback instead.

Video detected but won't play?

DRM content: Protected streams from major subscription services cannot be cast.
Format support: Your Vizio model may not decode that container or codec. Try a different source or quality.
Expired link: Some web video URLs expire. Reload the page and let CastBrowser re-detect the video.

Frequently Asked Questions

Does a Vizio TV have Chromecast built in?

Most Vizio SmartCast TVs include Chromecast built-in, which makes them a Google Cast receiver — no separate dongle needed. Support depends on the model and software version, and very old or non-SmartCast Vizio sets may not include it. Look for the SmartCast interface, or check whether casting apps detect the TV on your network.

How do I cast to a Vizio TV from my Android phone?

Install CastBrowser, join the same Wi-Fi as the Vizio TV, open a compatible website, and start the video. Tap the cast icon and pick your Vizio SmartCast TV. On models with Chromecast built-in, CastBrowser sends the stream over Google Cast and the TV plays it directly.

How do I cast to a Vizio TV from my iPhone?

Can I cast to a Vizio TV without Chromecast?

Yes. If your model lacks Chromecast built-in, CastBrowser can fall back to DLNA on models that support it, or to the CastBrowser Web Receiver opened in the Vizio browser where available. Both require your phone and TV to be on the same local network, and support varies by model.

Why won't my Vizio TV show up when I try to cast?

Usually because the phone and TV are on different or isolated networks — for example an isolated guest network, separate subnet, or VLAN. A router's 2.4 GHz and 5 GHz bands can normally reach each other, so the band is rarely the cause. Confirm both devices can communicate on the same local network, disable any VPN, and check your router for AP or client isolation.
