It is important to accurately identify any issues that you believe you might be having with your Vizio TV. This guide will provide detailed information regarding the common causes for Vizio TVs to be slow and also troubleshooting methods to help resolve these issues.

Slow and laggy performance is the bane of any technological device. These issues can be caused by several different things. Use the guide below to properly identify the root of your issue and apply the proper troubleshooting method.

At the end of this guide, you will be provided with several preventative measures so that you can ensure that your Vizio TV is always working properly. The list of common causes and fixes for a slow Vizio TV are as follows:

Why is My Vizio TV Slow

1. Poor Internet Connection

The most common cause of slow Vizio TV performance is an unstable or non-existent internet connection. Since your Vizio TV depends on the internet to access all of the included network functions, without a stable connection you will experience a slowdown in functionality.

This will affect you considerably if you are currently attempting to use the preinstalled streaming applications, web browser, or other network features on your Vizio while experiencing internet issues.

Before you will be able to resume the normal function of your Vizio TV, you will need to fix your internet issue by using one of the detailed troubleshooting methods below:

Fix 1 – Restart Internet Connection

The first thing that you should do if you are experiencing internet issues that are causing your Vizio to be slow is to restart the internet connection. You can do this by manually disconnecting from the Wi-Fi in your Vizio TV’s network settings.

You can access the network settings menu by opening the Settings menu from the home screen of your Vizio TV. Once you have done this, you will see the Network menu in the list.

In the Network menu, you can then manually disconnect from your current Wi-Fi connection and then reconnect. This will help encourage any connection errors that your Vizio TV might be experiencing to be resolved automatically.

Fix 2 – Restart Router

If restarting the internet connection did not resolve your issue with your Vizio TV’s slow performance, then you should next consider restarting your router. Almost all modern routers have a button that will initiate a restart of the router.

This button is generally located on the top or side of your router. Once you push this button to initiate a reset, the internet will be disconnected and reconnected from all of your devices.

This can help encourage the resolution of any connection errors that you might be experiencing as well as retransmitting your Wi-Fi signal fresh to all of your devices. Your Vizio TV will automatically reconnect to the newly refreshed Wi-Fi connection.

Fix 3 – Reset Your Router

If neither of the above solutions resolved your internet issues causing your Vizio TV to be slow, then you should consider resetting your router. To reset your router, you simply unplug it for at least sixty seconds.

Once you plug the router back in, it will begin the process of reestablishing an internet connection. This is the best way to resolve potential connection errors that you might be experiencing.

To ensure that this method is effective, consider leaving the router unplugged for five minutes. This will give the router itself more time to cool down if a potential overheating is causing your issue.

Fix 4 – Contact Your Internet Service Provider

In none of the above solutions resolved the internet problems causing your Vizio TV to operate slowly, then you are likely experiencing an internet outage. Internet outages can be expected after major storms or long bouts of extreme weather conditions.

Your internet service provider will be able to give you more details regarding your outage as well as offer more in-depth problem-solving methods specific to your situation. This is your best option if you are experiencing an internet outage.

You will likely be unable to access many of your Vizio TV’s network features during the outage and could experience a slow down of functionality.

2. Your Vizio TV Has Encountered A Bug Or Glitch

Another common cause for Vizio TVs running slow is bugs and glitches. Bugs and glitches are prevalent across all types of software applications, including the firmware that your Vizio TV depends on to function properly.

Bugs and glitches can cause a range of different errors that could affect the functionality of your Vizio TV. These errors include general slowdowns and more frequent bouts of unresponsiveness.

This is frustrating to encounter but bugs and glitches are typically rare and resolve themselves quite quickly. That being said, there are some proactive steps you can take to help encourage bugs and errors to be resolved.

Use the fixes below to help your Vizio TV recover from any potential bug or glitch that is causing it to be slow:

Fix 1 – Restart TV

The first thing you should attempt when trying to resolve bugs and glitches that are causing your Vizio TV to run slow is to restart your TV. Restarting your TV will end any potential run-time errors caused by a bug or glitch to be resolved upon restart.

This could also help to resolve any internet connection issues that you might be experiencing as well. A restart of your TV will end all of the current functions being carried out by the internals of your device.

Because of this, it is an effective way to help your Vizio TV recover from any bugs or glitches it has encountered and be restored back to normal functionality.

Fix 2 – Unplug Your TV For Sixty Seconds Then Plug it Back In

Power cycling is the act of unplugging your Vizio TV for sixty seconds and then plugging it back in. It serves a similar function as resetting your internet router. Being unplugged will allow your Vizio TV to completely shut down, ending any latent functions that continue even after the TV is powered off traditionally.

Once you have done this, any internal issues that your Vizio TV was experiencing will have been resolved automatically. Generally, this is a good method to consider if you have only recently begun experiencing slowdowns while using your Vizio TV.

Fix 3 – Clear Cache

Your Vizio TV data cache stores valuable user information that is used to help ensure faster startup. Most software applications that utilize user settings have some form of a data cache in place.

As the amount of data in this cache increases, so does the likelihood that one of the files contained there could potentially become damaged or corrupted. When this happens it could cause issues that extend to other parts of your Vizio TV.

Damaged data cache files could potentially be the cause of your Vizio TV slowdown issues. To remedy this, you should simply clear the cache data. To do this, you must first enter the Settings menu from the home page of your Vizio TV.

In the Settings menu, enter the Apps menu. From there you will be able to enter the System Apps menu, where you will find a list of all of the stored cache data and the apps related to them. Select the ones you would like to clear and click Clear Cache.

Once you have done this, you will have successfully cleared the cache on your Vizio TV. This will remove any damaged files that could potentially be causing your issue. The cache data folders will immediately begin to compile new data, so it is wise to periodically clear the cache if you notice them getting too full.

Fix 4 – Factory Reset Your Vizio TV

Just like the cache data stored on your Vizio TV, the files associated with your TV’s firmware could potentially become damaged or corrupted. When this happens your Vizio TV will start to experience frequent slowdowns and functionality issues.

This can also be caused by any third-party applications that you may have managed to install on your Vizio TV. Third-party applications can introduce malicious software onto your system that will need to be cleared before your Vizio can resume normal performance.

To perform a factory reset on your Vizio TV, you will first need to press the Menu button on your Vizio TV remote control. You will then need to enter into the System menu. There, you will find the Reset & Admin menu.

In the Reset & Admin menu, you will find the option to Reset TV to Factory Defaults. Select this option and enter the code 0000 when prompted unless you have set a code otherwise.

Confirm the reset and your Vizio TV will power off and begin the reset process. Once your Vizio TV has completed the factory reset, it will power back on you and will have to redo the initial setup process.

Keep in mind that a factory reset will clear all of your saved user data and applications from the TV and replace them with the factory defaults.

Fix 5 – Update Your Vizio TV

The most common cause of issues and general functionality errors is out-of-date software on your Vizio TV. Your TV relies on the most recent version of its software to function properly. These updates contain bug fixes and many quality-of-life optimizations for your device.

If you find that you are experiencing frequent issues with your Vizio TV, you could need an update. Your TV will automatically notify you of any updates available when it is connected to a valid internet connection.

The user will have to manually download the update and install it for it to be applied. This is a key step of the update process that many look over, so keep this in mind.

3. Your Vizio TV Has Too Little Storage

If your Vizio TV is nearing its storage capacity, then this will incur major slowdowns for your device. It is good practice to only fill the internal storage of any device to around eighty-five percent.

Leaving a little space will ensure that the operating system is left enough room to properly operate, as it will sometimes add and remove files associated with certain functions.

If the internal storage in your Vizio TV is filled ninety or more percent, it is very possible that the operating system is struggling to make room for processing files that it depends on to function smoothly.

Fix 1 – Make More Storage Space On Your Vizio TV

The best way to fix storage issues with your Vizio TV is to simply delete some applications and saved data from the device. You could consider deleting unused applications or apps that are taking up a considerable amount of space.

Depending on the model of Vizio TV you have, you may have to capability to add user files like pictures and videos to your device. If that is the case, consider deleting some of them from your Vizio TV.

Some Vizio TVs support USB drive storage to access user media. You could consider using a USB drive to view your photos and videos on your Vizio TV without having to store them there and use up valuable space.

4. Some Apps Are Using Up Too Much Bandwidth

Some extremely heavy bandwidth applications like high-definition streaming or cloud-gaming services could cause your Vizio to experience a significant slowdown. These applications could also be running static in the background even when not currently active on your Vizio TV.

If an application is using up too much bandwidth, the internals of your Vizio TV’s network adapter could struggle to keep up. This will cause a general slowdown when trying to access other functions of your Vizio TV.

Fix – Delete The Heavy Bandwidth Apps

The simplest thing you can do to remedy this issue is to delete the apps that are using a lot of bandwidth. These include streaming applications that utilize 4k ultra-HD or cloud gaming applications that stream games directly to your Vizio TV.

5. Your TV Is Old Or Damaged

One reason that your Vizio TV might have gotten slower over the years is due to the natural lifecycle of technology. The software that your Vizio TV depends on to function properly might no longer be supported. This is common with TVs, as new models are released all the time, phasing out older ones in the process.

The closer your Vizio TV gets to a decade in its lifetime, the more frequently you can expect to experience slowdowns and general functionality errors. That being said, if your TV has become damaged somehow, you can expect to experience these issues much sooner.

Any type of drop or spill that your Vizio TV has been exposed to could potentially cause damage to the internals that could cause a slowdown. Typically, you will be aware of your Vizio TV has incurred some type of significant damage.

Fix 1 – Replace Your Vizio TV

If you have an older model Vizio TV or one that has become damaged and is no longer in warranty and is beyond repair, then you should consider replacing your Vizio TV (view on Amazon) with a newer model.

Newer model Vizio TVs come packed with features and user optimizations that you will be able to notice immediately upon upgrading. Owners of newer model Vizio TVs will generally want to attempt to repair before replacing their whole device.

Fix 2 – Contact Vizio

If you experiencing persistent issues with your Vizio TV being slow, then you should consider contacting Vizio and having them further investigate your issue.

You can get in touch with Vizio on their website or by phone. You will need to provide an extremely detailed account of your issue so that Vizio Support can walk you through any potential troubleshooting methods that you might have missed.

They will then get back to you with detailed instructions on how to solve your problem. It can be frustrating to deal with customer support over the phone, but rest assured that Vizio Support will do everything they can to get your device up and running again.

Keep in mind that this should be considered as a last resort after trying all of the troubleshooting methods listed in this guide. This is because Vizio technical support is likely to suggest to you many of the troubleshooting methods already listed here. This can save you time when trying to get to the root of your issue.

6. You Have An Issue With Your Remote

If you are noticing that your Vizio TV is not responsive to the controls you issue with your remote control, the issue might not be with your TV at all. Your remote control could be experiencing some type of issue that is keeping it from communicating properly with your Vizio TV.

When this happens, it might appear that your Vizio TV is reacting slowly to your commands. This can be frustrating but remote problems are actually quite common to encounter with any modern TV.

Fix 1 – Re-insert Batteries

You should first reinsert the batteries of your remote to encourage any connection issues to be resolved automatically. Removing and reinserting the batteries will cause the remote to initiate an internal restart. This can help solve most remote issues.

Fix 2 – Replace Batteries

Your remote-control issues could be caused by dead or low batteries. When the battery life gets low in your remote control, it will have trouble communicating commands properly to your Vizio TV. Replacing the batteries (view on Amazon) will remedy this issue.

Fix 3 – Replace The Remote

If your remote has become damaged or you are experiencing persistent problems, you should consider replacing your remote control (view on Amazon). This can help ensure that your remote is working properly and allow you to gauge the root of your issue more accurately.

Fix 4 – Use Remote Closer To Your Vizio TV

If you are attempting to use your remote control to issue commands to your Vizio TV from too far away, you could experience issues transmitting the command. You should use your remote control from as close as possible and in an area free of any obstructions that could cause communication issues.

7. Loose Cable Connections

Loose cable connections are another common cause of slowdown issues with Vizio TVs. If you connect your TV to the internet using a LAN cable or utilize several HDMI hookups in your setup, then you could be experiencing issues if these components are not connected properly.

Fix 1 – Check Cable Connections

You should ensure that all of your cables are attached properly and securely to your Vizio TV. You should also ensure that the cable is attached securely to the device that your Vizio TV is receiving data from.
