Take Control of Your Cast Options: Removing Unknown Devices with Ease


“I’ve encountered an unrecognized device appearing on the casting options for both my phone and computer via Google. Specifically, there’s a Sony TV listed that I wish to remove. Could an expert guide me through the process of eliminating this device from my casting list? For reference, the device in question is shown in the image linked.”


Discovering an unrecognized device on your casting list can be unsettling, especially when it’s a device you don’t own or recognize. If you’re looking to remove a Sony TV or any other device that you haven’t authorized for casting, here are the steps you can follow to secure your devices and ensure your privacy.

Step 1: Identify the Device

First, ensure that the device you’re trying to remove is not one that you own or have access to. If it’s a public or shared device, such as a TV in a hotel or a shared living space, you may not be able to remove it from the network, but you can prevent your devices from casting to it.

Step 2: Check Your Google Settings

On your phone or computer, open the Google Home app. This app controls your casting settings for devices connected to your Google account. Locate the device in question and check its details. If it’s not a device you recognize or want to use, proceed to the next step.

Step 3: Forget the Device

In the Google Home app, find the Sony TV or the device you wish to remove. There should be an option to ‘Forget’ this device. Selecting this will remove it from your list of available devices for casting.

Step 4: Secure Your Network

To prevent unauthorized devices from appearing in your casting options, ensure that your Wi-Fi network is secure. Use a strong password and consider hiding your network from public view. You can also check your router’s settings to see if there are any devices connected that you don’t recognize and remove them.

Step 5: Adjust Your Device’s Casting Settings

If you’re using an Android device, navigate to Settings > Google > Devices & sharing > Cast options. Here, you can toggle the media controls for Cast devices on or off, giving you control over which devices can be cast to.

Step 6: Consult Manufacturer Support

If the device still appears after following these steps, consult the support resources for your specific device. They may have additional steps or measures you can take to remove the device and secure your network.


By following these steps, you should be able to remove any unwanted devices from your casting options and secure your network against future intrusions. Remember to regularly check your connected devices and maintain a secure network to protect your privacy.

I hope this guide helps you resolve the issue with the unrecognized device. If you need further assistance, don’t hesitate to reach out to the support team for your devices or network provider.
