  • There are several workarounds, such as shutting down the Chromecast device, navigating the TV’s settings, turning off guest mode on Google Home, changing the WiFi password, and creating a separate SSID.

Is It Possible to Disable Casting on TVs?

By design, the feature of TV casting, whether it’s built into the smart TV or through a Chromecast device, is designed to be as hassle-free and convenient as possible.

For instance, Chromecast devices and smart TVs will not set up specific devices or authorize access from various devices on the same network.

For that reason, casting is built so that anyone who is on the same WiFi network is capable of casting all kinds of media on the TV.

As a result, there aren’t any straightforward methods to disable the feature or prevent specific devices on the same network from casting media on the TV.

With that being said, there are several methods that can help you achieve what you want, but more about that is in the following section.

Methods to Disable TV Casting

Now that you know that disabling casting directly is not a straightforward process, here are some workarounds that you can use in order to prevent your TV from casting.

Each one of these methods has its advantages and drawbacks, and you can implement them separately or combine them to obtain the results you’re hoping for:

1. Shutting Down Chromecast

If you’re using a Chromecast device to stream your media through the TV, the simplest way to disable casting would be to shut it down.

You can do that by unplugging the device, as it doesn’t have a “turn off” button installed in it. Despite being the easiest and quickest method, you’ll still need to plug it back every time you want to use casting again.

2. Navigate the TV’s Settings

If you have a smart TV that is capable of direct casting without using Chromecast devices, you can disable its casting through the settings menu.

The process will vary from one model to another, and some brands even hide these features in secret menus that require a specific code to be activated, so you’ll have to check the specific method of your model if the option to disable casting isn’t available in the original settings.

3. Turn Off Guest Mode on Google Home

Guest mode is a feature in the Google Home app (the one that connects your devices with Chromecast), which allows guests and other nearby devices to access your Chromecast through a pin code without needing to be connected to the same WiFi.

To disable it, open the Google Home app, then tap the settings gear icon at the top. Choose the “Recognition and Sharing” tab, then disable the Guest mode.

4. Change Wifi Password

This method is ideal if your TV starts casting media on its own, which usually happens due to other people connected to your WiFi, especially if you live in an apartment or with various roommates.

To change your WiFi password, you’ll have to access your router settings by typing the corresponding link on the back of the router (usually 

After that, you’ll need to enter your ID and current router password. Once you’re in, you can change the WiFi name and password with relative ease. 

Keep in mind that sharing the password with others again will cause the same problems, so only share it with people you trust.

5. Creating a Separate SSID on Router Settings

Lastly, this method is one of the best ways to enjoy private TV casting without worrying about others accessing the TV, even if they’re on the same network. 

The method may vary depending on your router model, but it should be something like the following:

  1. Access the router settings as mentioned in the previous method
  2. Click “Advanced Settings”, then “Wireless Network”.
  3. Enter the router’s password again if you’re prompted with a password box
  4. Click “Create a new SSID”
  5. Set the name and password of the new network
  6. Connect your TV and your phone to the new SSID and don’t share its password with anyone.

Wrap Up

There you have it! A brief guide that walks you through everything you need to know about TV casting and whether you permanently turn that option off.

As you can see, TV casting is built for convenience and ease of use, so any device that is on the same network will be able to cast media on the TV.

Luckily, the previously mentioned workarounds can help you avoid this problem, but each one of them has its own pros and cons, so make sure that you pick the one that suits you best!
