Keeping your Vizio Smart TV’s firmware up to date is one of the most important things you can do to ensure a great long-term ownership experience. Firmware updates deliver new features, improve compatibility with streaming services and connected devices, fix bugs that may affect performance or stability, and apply security patches that protect your TV and your home network. Vizio regularly releases firmware updates for SmartCast TVs, and the update process is straightforward whether your TV is connected to the internet or not. This guide covers manual updates, automatic updates, USB-based updates for offline TVs, and what to expect before, during, and after the update process.
Never power off your Vizio TV during a firmware update. Interrupting the update process can corrupt the TV’s firmware, potentially causing it to become unresponsive. If a power outage is likely, wait until conditions are stable before initiating an update.

​
Check for Updates Manually

If you want to check for and install the latest firmware immediately, you can trigger a manual update check at any time from the System settings menu. Your TV must be connected to the internet via WiFi or ethernet for this method.
1

Press Menu on Your Remote

Press the Menu button on your Vizio remote. The Settings panel will appear along the right side of the screen.
2

Navigate to System

Use the arrow keys to highlight System and press OK to open the System settings menu.
3

Select Check for Updates

Scroll down to Check for Updates and press OK. Your TV will connect to Vizio’s update servers and check whether a newer firmware version is available for your specific model.
4

Review the Update Information

If an update is available, the TV will display the new firmware version number and a brief description of what the update includes. Review this information, then highlight Confirm or Install Update and press OK to begin the download and installation.
5

Wait for the Update to Complete

The TV will download the update, apply it, and automatically restart. This process typically takes between 5 and 15 minutes depending on the size of the update and your internet connection speed. The screen may go black and the TV’s power light may flash during this time — this is normal.
6

Confirm Successful Update

After the restart, your TV will return to the home screen. You can verify the update was successful by checking the current firmware version under Menu → System → System Information.
If you have recently completed your initial TV activation at vizio.com/setup, it is recommended that you check for firmware updates immediately after setup. The TV that shipped from the factory may have older firmware, and updating right away ensures you have access to all the latest features and fixes from the start.

​
Enable Automatic Updates

Rather than manually checking for updates, you can configure your Vizio TV to download and install firmware updates automatically whenever one becomes available. This is the most convenient option for most users.
1

Open the System Settings Menu

Press Menu on your remote, navigate to System, and press OK.
2

Select Check for Updates

Highlight Check for Updates and press OK.
3

Enable Auto Update

Look for the Auto Update option (some firmware versions label this Automatic Updates or Auto Firmware Update). Highlight it and press OK to toggle it On.
4

Confirm the Setting

Once enabled, your TV will automatically check for and apply firmware updates during overnight hours when the TV is in standby mode, minimizing any disruption to your viewing experience.
Enable Auto Update on your Vizio TV so you always have the latest firmware without needing to remember to check manually. Updates typically install overnight during standby, so you will rarely notice them happening.

​
What Happens During an Update

Understanding what the TV does during a firmware update helps you know what to expect and what not to worry about.

Download Phase

The TV downloads the firmware package from Vizio’s servers over your internet connection. Download size varies but is typically between 200 MB and 1 GB. You will see a progress indicator on screen. The TV remains usable during this phase on some models.

Installation Phase

After the download completes, the TV begins flashing the new firmware to its internal storage. The screen will go dark and the TV will not respond to remote inputs during this phase. This is the most critical stage — do not unplug the TV.

Restart Phase

Once installation is complete, the TV automatically reboots itself. You will see the Vizio startup screen as it powers back on. The reboot may take slightly longer than a normal startup as the system initializes the new firmware.

Post-Update Initialization

On the first boot after an update, the TV may take 30–60 seconds longer than usual to reach the home screen as it completes any background configuration tasks associated with the new firmware version.
The entire process from starting the download to returning to the home screen typically takes 5 to 15 minutes for most updates. Larger major firmware releases may take up to 30 minutes on slower internet connections.

​
How to Check Your Current Firmware Version

Before or after updating, you can check which firmware version your TV is currently running. This information is also useful when contacting Vizio support.
1

Open System Settings

Press Menu on your remote, navigate to System, and press OK.
2

Select System Information

Scroll down to System Information (some models label this About TV) and press OK.
3

Locate the Firmware Version

The System Information screen displays your current firmware version number, along with other details such as the TV’s model number, serial number, and MAC address. Note the firmware version number if you need it for support purposes.

​
Update via USB Drive

If your Vizio TV is not connected to the internet, you can still update the firmware manually using a USB flash drive. This method requires a computer with internet access to download the firmware file from Vizio’s website.
1

Find Your TV's Model Number

Your TV’s model number is printed on a label on the back of the set. It is also visible under Menu → System → System Information if you can access the menu.
2

Download the Firmware from Vizio's Website

On a computer, go to vizio.com/setup and navigate to the Support section. Search for your TV model and locate the Firmware Downloads page. Download the latest firmware file for your model — it will be in a .zip format.
3

Prepare the USB Drive

Use a USB flash drive formatted as FAT32 with at least 2 GB of free space. Extract the downloaded .zip file and copy the firmware file (typically a .pkg file) to the root directory (top level) of the USB drive — do not place it inside any folders.
4

Insert the USB Drive into Your TV

Insert the prepared USB drive into one of the USB ports on your Vizio TV. The TV should detect the firmware file automatically.
5

Follow the On-Screen Prompts

Your TV will display a prompt asking if you want to install the detected firmware update. Select Yes or Install and press OK. The installation process is identical to an online update — the TV will install the firmware and restart automatically.
6

Remove the USB Drive After Reboot

Once the TV has restarted and returned to the home screen, you can safely remove the USB drive.
Only download firmware files from the official vizio.com/setup support portal or the official Vizio website. Never use firmware files obtained from third-party websites, as they may be modified, incomplete, or incompatible with your specific TV model.

​
After the Update

Once your TV restarts after a firmware update, you can expect the following: Settings are preserved. In the vast majority of cases, all your display settings, audio preferences, WiFi configuration, and app logins are retained after a firmware update. You should not need to reconfigure your TV from scratch. SmartCast and apps may update. After a firmware update, SmartCast and individual streaming apps may perform their own updates in the background. The TV home screen may load slightly slower than usual for the first few minutes as this background activity completes. Re-pairing your remote may occasionally be needed. In rare cases — particularly after major firmware releases — Bluetooth-paired SmartCast remotes may need to be re-paired. If your remote stops responding after an update, hold the V button on the remote for 3 seconds to initiate re-pairing. Full remote pairing instructions are available in the Pair Your Vizio Remote guide. New features may appear in the menu. Firmware updates sometimes add new settings, options, or menu items. It is worth browsing the Settings menu after a major update to discover anything new.

​
Firmware Update Troubleshooting

If the update download fails, first check your internet connection — run a quick test by loading an app like Netflix. If the connection seems slow or unstable, try moving your TV closer to your WiFi router or connecting via ethernet. Power cycle your router and try the update again. If the download consistently fails, try the USB update method described above as an alternative.
If the TV appears frozen during the installation phase — the screen is black or shows a static progress bar for more than 30 minutes — wait at least 45 minutes before taking any action, as some larger updates take longer than expected. If the TV still shows no progress after 45 minutes, carefully unplug the power cord, wait 60 seconds, and plug it back in. In most cases the TV will recover and either continue or complete the update on restart. If the TV fails to boot after this, contact Vizio support.
If the Check for Updates screen reports that your TV is up to date but you believe a newer firmware version exists, verify your internet connection is working and try the check again after a few hours. Vizio often staggers firmware rollouts, pushing updates to a percentage of devices at a time rather than all at once. Your TV will receive the update during the next rollout window. You can also try the USB update method to install the latest version immediately.
Repeated reboots (a reboot loop) after a firmware update are uncommon but can occur. First, unplug the TV from power for 60 seconds and plug it back in. If the loop continues, try performing a factory reset by pressing and holding the Input and Volume Down buttons on the TV (not the remote) simultaneously for 10 seconds. This resets the TV to factory state, after which you can set it up again and re-apply the update. If this does not resolve the issue, contact Vizio customer support.
