Tired of squinting at your favorite YouTube videos on a small phone screen? Elevate your viewing experience by casting YouTube directly from your phone to a larger PC display. This guide will walk you through the steps needed to set up your PC for casting and connect your devices seamlessly.
Configure Your PC for Casting
Casting to other devices, like TVs or gaming consoles, typically involves a simple tap on your phone. However, casting from a phone to a PC requires a bit more setup.
First, you will need to enhance your browser’s capabilities. Install the Custom UserAgent String extension on Chrome. This tool allows your PC’s Chrome browser to mimic a smart TV or similar device, specifically tailored for casting.

After installation, check the extensions bar for the new blue icon. If you don’t see it, navigate to the Chrome menu and select Extensions → Manage Extensions. Ensure it is enabled.

For quick access, click on the Extensions icon (puzzle piece) beside the URL box in Chrome and pin the extension to your browser’s extensions bar by clicking the pushpin icon.

Click the blue Custom UserAgent String icon in the extensions bar and select Open options page.

In the box labeled “Enter a desired URL, ” input https://youtube.com/tv.

In the adjacent box, enter the following user agent string:
Mozilla/5.0 (Linux; Tizen 2.3) AppleWebKit/538.1 (KHTML, like Gecko)Version/2.3 TV Safari/538.1

This setup will ensure that when you access youtube.com/tv, Chrome will act as if you were using a Samsung TV app, making it available for casting.
Don’t forget to confirm the settings by clicking the “+” icon to the right.

This method is compatible with most Chromium-based browsers, and there is also a similar extension available for Firefox users.
Linking Your Phone and PC
Open Chrome and navigate to youtube.com/tv. Click on Get Started and scan the QR code displayed with your phone to begin the sign-in process. This mirrors the sign-in method typically employed on smart TVs.
In the YouTube app on your phone, click the Cast icon in the upper right corner and select Link with TV code.

Return to YouTube on Chrome and select Settings → Link with TV Code. Enter the code displayed on your PC into the YouTube app on your phone.

Once linked, tapping the “Cast” icon at the top of your YouTube app should reveal your PC as a streaming option, likely labeled as “YouTube on TV.” Select your device and enjoy your videos on the big screen.
Casting YouTube from Android to Windows
If you’re using an Android device along with Windows 10 or later, take advantage of the integrated Phone Link feature. Follow the steps to connect your Android device to your Windows PC; this process should only take a few minutes.
After a successful connection, navigate to Apps in the Phone Link application on your Windows device. Find YouTube within the app list, then confirm the settings on your Android phone to enable mirroring. Note that performance can vary, so if the streaming seems sluggish, consider adjusting your settings. Alternatively, you can select Open Phone Screen in the Phone Link app and launch YouTube through your mirrored Android screen. Expanding a video will display it in a larger format on your PC as well.

Casting YouTube from iPhone to Mac
The simplest method for iPhone users is to utilize Apple’s AirPlay feature to cast YouTube content directly to a Mac. Ensure that both devices are connected to the same Wi-Fi network for optimal performance.
Begin by opening the YouTube app and starting playback of your desired video. Tap the Cast icon at the top of the video, then select AirPlay and Bluetooth Devices, choosing your Mac from the list.

For a more comprehensive experience, utilize the Screen Mirroring feature by opening the Control Center on your iPhone, tapping the Screen Mirroring button, and selecting your Mac. This allows you to mirror your entire screen while controlling YouTube from your iPhone.

Troubleshooting Common Issues
Encounter issues while attempting to cast from your phone to PC? If your device is outdated, it may not support casting functionalities.
For the Custom UserAgent String setup, ensure there are no inadvertent spaces in the URL, as this can cause redirection errors. Verify that only one YouTube TV entry is present.
When using the Android to Windows or iPhone to Mac casting options, the most common problems arise from connectivity permissions. Double-check the settings on both your mobile and desktop devices to ensure proper access.
Now that you’ve grasped the essentials of casting, consider sharing your viewing experience with friends online. You might also explore removing Shorts to discover more of the content you love.
