Vizio Smart TV Not Casting – Let’s Fix Now
Tip: You can check if your Vizio TV supports Chromecast or VIA/VIA+ by consulting with the user manual or browsing the settings.
1. Use the Same Wi-Fi On Both Devices

The first and most important requirement your setup must meet in order to use wireless casting is to be on an identical Wi-Fi network for both devices.
So, having your smartphone, tablet, or computer using a different network from the Vizio TV will disallow wireless casting in its entirety.
1.1 How to Check the Wi-Fi Network On Vizio TV?
- Press the “Menu” button on your Vizio TV remote control.
- Select “Network” and press “OK” to access the next tab.
- Choose “Network Connection” and highlight “Wireless.”
- Check the current network your Vizio TV is connected to.
Most Vizio TVs come without a built-in 5 GHz Wi-Fi, so you will be limited to only connecting with 2.4 GHz networks.
While browsing the connection list on your TV, make sure to connect with a home Wi-Fi that starts with “2.4 GHz,” otherwise the connection may fail.
1.2 How to Check the Wi-Fi Network On Most Devices?
- Open the “Settings” app and go to “Network” or “Wi-Fi.”
- Search for a “Connected” status under any of the Wi-Fi’s.
- If not connected, pair the device to the same Wi-Fi as TV.
Keep in mind that the Vizio TV and the device you cast from must also be on the same Wi-Fi thread.
If you have a dual-band router with a 2.4 GHz and 5 GHz thread, ensure both the TV and your device are on the 2.4 GHz Wi-Fi.
2. Cast Through a Different Application

To determine whether the issue is with the Vizio TV, we recommend casting through a different Cast-enabled app.
Even if the Vizio TV does not support Chromecast, most streaming apps with an in-built screen mirroring feature should detect the TV right away.
Well, some of the popular cast-enabled applications include YouTube, Netflix, Prime Video, Disney+, Paramount+, Crunchyroll, and more.
Feel free to test the casting through multiple different applications, to determine if the Vizio TV can be discovered.
Inspect Your Device’s Connection!
Also, before proceeding with the next step, ensure your device maintains a stable and persistent connection to the Wi-Fi.
Even the slightest fluctuation in the Wi-Fi could prevent the device from casting content on your TV.
So, we recommend reconnecting the device from the Wi-Fi by going into the “Wi-Fi” settings and testing through other online platforms.
3. Troubleshoot Issues with the Network

If you’re still asking “why is my Vizio Smart TV not casting,” it could be due to an underlying issue with the network.
All equipment from your network, including the router, is responsible for allowing various Cast-enabled apps to discover your Vizio TV.
Let’s review different possible ways to address issues with the network!
3.1 Power Cycle the Network Router
The first and one of the most effective steps is to unplug the router’s power adapter.
It takes less than a minute for the router’s residue current to drain once the adapter is disconnected, so wait for at least 30 seconds.
3.2 Inspect the Service Connection
Well, even if your router is connected and visibly working, a fault with the service connection will disrupt the “Online” status of all connected devices.
Ensure the router is tightly connected to the service outlet or modem provided by the ISP.
3.3 Reset the Router’s Configuration

We recommend only proceeding with this solution if multiple devices from your Wi-Fi/network are experiencing connection issues.
Check if there’s a “RESET” button on the rear or side panel of the router and erase all settings to factory defaults.
Alternatively, you can use the router’s default gateway to access the web GUI and initiate the factory reset there.
The default login credentials for almost all routers are “admin/admin” or “admin/password.”
Note: If the connection faults persist, get in touch with the ISP for further troubleshooting!
4. Update Vizio TV’s Firmware Version

The Vizio TV could be failing to cast because of an outdated firmware version.
Both the Vizio TV and the Cast-enabled application must be updated to the most current firmware build, to cast the compatible platform content.
Here’s how to check the firmware version of the Vizio TV:
- Press the “Menu” button on the Vizio TV remote control.
- Access the “Admin and Privacy” section from the page.
- Next, press the “Check for Updates” function and wait.
- If a new update is available, follow the on-screen steps.
The Vizio TV must be securely connected to a Wi-Fi network in order to conduct the firmware update.
Once the procedure starts, cease all interactions with the TV for the next 5–10 minutes.
5. Try to Cast Through a Different Device

Perhaps, the fault is with the casting device, rather than the Vizio TV or your Wi-Fi/broadband.
Solely for testing purposes, we advise attempting to cast through a different device compatible with the technology that’s also connected to the same Wi-Fi as the Vizio TV.
All you need is to download a Cast-enabled app through the Google Play or App Store, and power on the Vizio TV.
What Cast-Enabled Devices Can I Use?
As long as the device is on the same Wi-Fi as the TV, you can use almost anything for casting!
If you’re wondering how it is possible to cast content from a PC, all you need is an up-to-date Chrome browser to discover and cast browser content to your TV.
As for mobile, most of the popular streaming platforms/apps have built-in casting options that can discover your Vizio TV.
6. Factory Reset the Vizio TV’s System

A factory reset will almost certainly resolve the Vizio TV not smart casting issue.
Well, we only recommend this step if you’ve tried all solutions so far and nothing seems to help with restoring the casting capabilities of the TV.
Warning: The factory reset will permanently erase ALL your Vizio TV settings to default!
Follow these simple steps to factory reset the Vizio TV:
- Access the menu page on your Vizio TV, using the remote.
- Follow one of these paths, based on your Vizio TV’s model:
- Go to “Admin & Privacy” → “Reset to Factory Settings.”
- Go to “System” → “Admin & Privacy” → “Reset to Factory Settings.”
- Go to “All Settings” → “Admin & Privacy” → “Reset to Factory.”
- Enter the default PIN of the TV required for the factory reset.
- Confirm the procedure and follow the on-screen instructions.
Alert: Do not interact with the Vizio TV once the restoration starts!
