How to Cast from Phone to TV Wirelessly: Complete Guide
Wireless casting lets you display your phone’s screen on a television without cables or physical connections. Whether you want to share photos, stream videos, or mirror entire applications, modern smartphones and smart TVs offer several built-in methods to accomplish this. The process varies depending on your device brand, TV type, and the content you wish to display.
The technology relies on both your phone and TV being connected to the same Wi-Fi network, allowing them to discover and communicate with each other. Most manufacturers have integrated screen mirroring directly into their devices, eliminating the need for additional hardware in many cases. Understanding which protocol your devices support will help you choose the most reliable method for your setup.
How to Cast from Phone to TV Wirelessly
Before exploring specific methods, it helps to understand the four primary approaches available for wireless casting. Each works differently depending on your device compatibility and intended use.
Google TV/Chromecast app
AirPlay to compatible TV
Smart View feature
Screen Share/Miracast
Regardless of which method you use, one fundamental requirement remains constant: both your phone and television must be connected to the same Wi-Fi network. Without this connection, the devices cannot discover each other, and your TV will not appear in the list of available casting targets. The IEEE 802.11 standard forms the foundation of this wireless connectivity, enabling the protocols that make screen mirroring possible.
Key Things to Know About Wireless Casting

The Google TV app provides a structured approach for Android users. Open the Google TV app on your phone and tap “TVs nearby” near the bottom right of the screen. Select your intended device from the available options, then enter the code displayed on your television screen. Tap “Pair” to establish the connection.
For casting specific videos, follow the same initial steps, then select the show or video you want to watch and tap “Watch on TV.” The content will stream directly to your television while your phone acts as a remote control.
Google Home App Method
The Google Home app offers another casting pathway for Android devices. Open the app and locate a device that supports mirroring. Tap to open the device settings, then select “Cast entire screen.” Confirm by choosing “Cast screen” to begin the mirroring session. When you want to stop, return to the device menu and tap “Stop casting.”
Google Pixel devices feature built-in OS-level casting that can work around certain app restrictions. For example, Pixel phones can cast audio from YouTube even without a subscription, something not possible on all Android devices.
How to Cast to TV from iPhone
iPhone users rely on AirPlay, Apple’s proprietary wireless streaming protocol, to cast content to compatible televisions. AirPlay comes built into iOS, requiring no additional app downloads for basic functionality.
AirPlay Requirements
Your iPhone and Apple TV or AirPlay-compatible smart TV must be on the same Wi-Fi network. Compatible televisions include models from Samsung, LG, Vizio, and Sony that support AirPlay 2. You can verify compatibility by checking the manufacturer’s specifications or looking for the AirPlay logo on the TV’s packaging.
Mirroring Your iPhone Screen
To mirror your entire iPhone display, open Control Center by swiping down from the top right corner of your screen. Tap “Screen Mirroring” and select your TV from the list. If prompted, enter the AirPlay code shown on your television. Your iPhone screen will now appear on your TV in real time.
Casting Specific Content
Many apps support direct AirPlay streaming without full screen mirroring. When viewing photos, videos, or music in compatible apps, tap the AirPlay icon (a rectangle with an upward triangle) and select your TV. The content will stream while your phone remains available for other tasks. The Apple AirPlay ecosystem extends well beyond Apple’s own devices, allowing seamless integration with third-party smart TVs that support the protocol.
For frequently used AirPlay destinations, your iPhone remembers previously connected devices, making subsequent connections faster. You can also use Siri to control AirPlay on compatible devices.
How to Cast from Phone to TV on Samsung and LG
Samsung and LG televisions each have their own casting ecosystems optimized for their respective smartphone lines. Understanding these brand-specific features helps you get the most from your devices.
Samsung Smart View
Samsung phones use the Smart View feature for wireless screen mirroring. Access it through Quick Settings by swiping down from the top of your screen. Select Smart View from the available options, and your phone will search for compatible Samsung TVs on your network.
When your TV appears, tap to connect. You may need to approve the connection on your television screen. Once paired, your phone’s display mirrors to the TV, and you can use your phone while content appears on the larger screen.
LG Screen Share and Miracast
LG smart TVs support the Wi-Fi Display standard, which allows Android phones and other compatible devices to cast without additional hardware. LG also provides the Screen Share app for enhanced functionality.
To use Screen Share on your LG TV, navigate to the Home menu and select Screen Share. On your Android phone, access screen mirroring through Quick Settings and select your LG TV from the available devices. The connection uses Miracast technology for low-latency display.
Many LG televisions also support Intel WiDi (Wireless Display), providing an alternative mirroring protocol for compatible devices. This can be useful if standard Miracast connections experience issues.
Not all phone models from Samsung or LG support every casting feature. Older devices may have limited options or require additional apps. Check your specific model’s documentation for supported protocols.

Understanding Screen Mirroring Protocols
Different wireless casting technologies have distinct characteristics that affect how content is delivered to your television. Understanding these differences helps you choose the right method for your needs.
Chromecast and Google Cast
Google’s casting technology operates differently from traditional mirroring. When you cast a video, your phone tells the casting device to pull content directly from the internet service (like Netflix or YouTube) rather than streaming it through your phone. This means your phone can perform other tasks while content plays, and the quality depends on the TV’s internet connection rather than your phone’s processing.
Physical Chromecast devices plug into your TV’s HDMI port and require a Wi-Fi connection. The dongle handles all streaming processing, making even older televisions capable of smart casting features. The Google Cast protocol has become one of the most widely adopted casting standards across apps and devices.
Miracast Standard
Miracast uses peer-to-peer Wi-Fi Direct connections, meaning devices can communicate without a traditional network router. This makes it useful in environments with limited or no Wi-Fi coverage. The standard supports full HD mirroring and is built into many televisions from manufacturers including LG, Panasonic, and Sony.
For devices without native Miracast support, you can purchase Miracast dongles that plug into HDMI ports to add the capability. Similarly, Chromecast dongles can provide casting features to non-smart TVs.
The method your phone uses to send content differs based on what you’re casting. Streaming services communicate directly with your TV through the casting device, while local files (photos, videos, music stored on your phone) transmit directly from your device to the television.
What Experts and Manufacturers Say
When casting to a TV, your phone acts as a remote control, instructing compatible apps to send content directly to the casting device rather than to your phone’s screen.
Most modern Android phones and smart TVs support wireless screen mirroring, which displays your entire phone screen on the TV in real time, including apps, media, and settings.
Support documentation from Google, Samsung, and Apple consistently emphasizes the importance of network configuration as the first troubleshooting step. When devices fail to discover each other, the solution in the majority of cases involves verifying both devices share the same Wi-Fi connection.
Summary and Next Steps
Wireless casting from your phone to a television has become increasingly accessible with built-in support across major smartphone and TV platforms. Whether you use Android’s native mirroring, Apple’s AirPlay, Samsung’s Smart View, or LG’s Screen Share, the fundamental requirement remains the same: both devices must communicate through a shared Wi-Fi network. For users experiencing connectivity issues, checking your Broadband Speed Test UK results can help identify network issues affecting casting performance. If your television lacks built-in casting capabilities, hardware solutions like Chromecast or Miracast dongles provide cost-effective alternatives that work across device brands.
