Product Owners Apple While built-in AirPlay technology is a unique advantage, other brands of TVs may require additional steps. In this article, we'll explore all the current methods for quickly and efficiently displaying your device's content on the big screen. You'll learn about the system's native features and proven third-party solutions.
Preparing equipment and network
Before you begin setup, you need to make sure that both devices – your smartphone and TV – are connected to the same network. Wi-FiThis is a critical requirement, as video streaming requires a stable local connection. If your router supports dual-band mode, it's best to use the frequency 5 GHz to ensure high throughput.
Make sure the software on both devices is updated to the latest versions. On TVs with Smart TV It's often necessary to update built-in apps or the system firmware itself for data transfer protocols to work correctly. Older software versions may simply not recognize new devices on the network.
⚠️ Note: If you have a dual-band router, make sure your phone and TV are connected to the same frequency (for example, both to 5 GHz), as some routers isolate devices on different bands from each other.
It's also worth checking your smartphone's battery, as actively streaming video can significantly accelerate battery drain. For longer sessions, it's best to keep the device close to a charger or use wireless charging, if supported.
Using AirPlay 2 technology
The easiest and highest quality way to transmit images is available to owners of TVs that support AirPlay 2This standard is built into many modern models from Samsung, LG, Sony, and other manufacturers, allowing for high-definition video transmission without lag.
To start casting, open Control Center on your iPhone. Depending on your device model, this can be done by swiping down from the top-right corner of the screen or swiping up from the bottom edge. Find the "Screen Mirroring" icon (two rectangles) and select your TV from the list of available devices.
After connecting, the image from the smartphone screen is completely mirrored on your TV. You can switch between apps, reply to messages, and the image on the big screen will change accordingly. To stop the broadcast, open Control Center again and tap "Stop Repeat."
Some applications such as YouTube or Netflix, have their own casting button that works over AirPlay. In this case, the phone acts as a remote control, and the video is buffered directly on the TV, saving battery life and allowing the smartphone to be used for other tasks.
Broadcasting via TV producer apps
If your TV doesn't support AirPlay directly, manufacturers often release their own apps for remote control and streaming. For example, for devices Samsung the application is used SmartThings, and for LG — LG ThinQThese utilities allow you not only to manage the menu but also to transfer media files.
The setup process is usually standard: download the official app from the App Store, launch it, and follow the on-screen instructions. The program will find your TV on the local network and prompt you to pair the devices, often requiring you to enter a code displayed on the TV screen.
These apps often feature a dedicated "Cast" button or media file icon, allowing you to select a photo or video from your iPhone's gallery and send it to the big screen. The quality of the stream depends on the codec implementation in the specific app and may be inferior to native AirPlay.
The advantage of using proprietary utilities is access to additional features, such as volume control, switching signal sources, or even using the smartphone as a touchpad. This makes interacting with the TV more flexible, especially if the original remote is lost.
Third-party mirroring apps
When built-in methods don't work or your TV is older, universal streaming apps come to the rescue. The leaders in this niche are Replica, ApowerMirror And TV AssistThey use standard DLNA protocols or their own algorithms for screen capture.
Most of these apps require installing a companion app on your TV. This app is usually available in the official Smart TV app store (for example, Samsung Apps or LG Content Store). Once installed on your TV and iPhone, they connect via IP address.
It's worth keeping in mind that free versions of such programs often have limitations, such as watermarks on images, session time limits, or lower image resolutions. Paid subscriptions remove these limitations and provide more stable performance.
Why might the video be lagging?
Delays often occur due to Wi-Fi channel congestion from neighboring networks or the low speed of the processor in the TV itself, which is unable to decode the stream in real time.
When using third-party software, it's important to grant the necessary permissions in iOS. The system may request access to the local network and the ability to record the screen without confirmation. broadcast It won't start. This is a standard Apple security procedure.
Setup via Google Chromecast
If your TV has a built-in module Chromecast or if an external Google dongle is connected to it, the streaming process will be different. You'll need an app to work with it. Google Home, which acts as a central hub for smart home and media control.
Once you set up your device in the Google Home app, you'll be able to cast a browser tab. Chrome or the entire screen. Open the app, select your device, and tap the "Cast Screen" button. This method has minimal latency, and image quality adapts to your network speed.
A unique feature of Chromecast is its extensive use of Google cloud services. Many apps that support this standard allow you to stream content directly, without overloading your phone's processor. This is ideal for streaming services.
| Method | Required software on TV | Quality | Delay |
|---|---|---|---|
| AirPlay 2 | Built-in (native) | High (4K HDR) | Minimum |
| SmartThings / ThinQ | Manufacturer's application | Medium/High | Low |
| Third-party (Replica) | Receiver | Depends on the software | Average |
| Chromecast | Built-in / Dongle | High | Low |
Troubleshooting and configuring the network
If the connection fails, first check your router settings. Function AP Isolation Access Point Isolation (API) is often enabled by default on guest networks and prevents devices from seeing each other. It should be disabled in the Wi-Fi security settings.
Problems can also be caused by antivirus software or firewalls, if installed on your router. Try temporarily disabling traffic filtering or creating a separate guest network without restrictions for your media devices.
☑️ Connection diagnostics
In some cases, resetting network settings on your iPhone can help. Go to Settings → General → Transfer or reset iPhone → Reset and select "Reset network settings." This won't delete your data, but it will return your Wi-Fi configuration to factory defaults.
⚠️ Note: TV interfaces and iOS versions are constantly being updated. The layout of menu items may differ from those described, so please consult the official documentation from your model's manufacturer.

This depends on the aspect ratio of the video and the screen. Try changing the scaling settings on your TV remote (P.Size or Aspect Ratio button).
The video is lagging while streaming, what should I do?
Try lowering the video quality in the source app, moving closer to the router, or rebooting the router to free up some bandwidth.
Do older TVs support iPhone streaming?
Yes, if you use external set-top boxes (Apple TV, Chromecast) or special receiver applications installed on Smart TV.
Does the operator charge for traffic when broadcasting?
If you use your home Wi-Fi, your mobile data plan won't be used. If you share your phone's data plan, your mobile data plan will use the data.
