Modern smartphones have powerful multimedia capabilities, but even the highest quality display iPhone It can't compare to the large screen of a home TV. You often need to show photos from a family vacation, watch a movie from an online cinema, or present a presentation to colleagues on a big screen. Fortunately, wireless technology makes this possible in seconds, without the hassle of wires and adapters.
The main tool for Apple technology owners is the protocol AirPlay, which is built directly into the iOS operating system. It enables high-definition video and audio streaming with minimal latency. However, not all TVs support this standard natively, requiring the use of additional software or devices.
In this article, we'll cover all the ways to sync your smartphone with your TV in detail. You'll learn how to set up a connection using the system's built-in features, which apps to install if your TV doesn't support Apple TV, and how to troubleshoot common connection issues.
Technical requirements and equipment preparation
Before you begin setting up your broadcast, you need to make sure your equipment meets the minimum requirements. A fundamental requirement is the availability of Wi-Fi module on the TV. Older plasma or LCD TVs without Smart TV support won't be able to receive a signal directly from your smartphone.
It's important to understand the difference between operating system versions. For Screen Mirroring to work reliably, your iPhone must be running iOS 11.4 or later, although older versions are sufficient for basic video streaming from apps like YouTube or Netflix. Your TV must also be running the latest firmware.
Network configuration is critical. Both devices—the smartphone and the TV—must be connected to the same Wi-Fi networkIf your router broadcasts signals on 2.4 GHz and 5 GHz frequencies with different names (SSIDs), make sure the devices can see each other while on the same network segment.
⚠️ Attention: Some providers use a "client isolation" feature on public networks or guest Wi-Fi. In this mode, devices cannot exchange data with each other, even when on the same network. To stream from an iPhone to a TV, this feature must be disabled in the router settings.
Also, check your smartphone's battery. Streaming high-definition video and constantly using Wi-Fi significantly increase power consumption. It's recommended to keep your phone close to a charger or ensure the battery is at least 30-40% charged before starting extended viewing.
Modern Smart TVs from Samsung, LG, Sony, and other manufacturers regularly update their software. The menu interface and item names may change. If you don't find the option described, check for firmware updates for your TV in the "Support" or "About" sections.
Using the built-in AirPlay 2 feature
The easiest and highest quality way to broadcast content is to use native technology. AirPlay 2This protocol allows not only screen mirroring but also direct video streaming from the server to the TV, freeing up the iPhone's processor resources. Many modern TV models support AirPlay 2, including Samsung (series 4-8), LG (webOS 4.0 and above), Sony, Vizio, and Roku TV.
To get started, make sure the feature is enabled on your TV. On most models, this happens automatically when an Apple device is detected, but sometimes you need to enable it manually in the settings. For example, on LG TVs, the path might look like this: Settings → Device Connection → AirPlay and HomeKit List, where you need to move the switch to the "On" position.
Once your TV is ready, open Control Center on your iPhone. On models with Face ID, swipe down from the top-right corner of the screen; on models with a Home button, swipe up from the bottom edge. Find the icon Screen Mirroring (two rectangles).
- 📱 Click on the icon and select your TV from the list of available devices.
- 🔢 If a four-digit code appears on the TV screen, enter it on the smartphone screen to confirm pairing.
- 🖥️ Your iPhone screen will instantly be displayed on your TV in landscape orientation.
If you're streaming video from apps that support AirPlay (YouTube, Netflix, Kinopoisk, Apple TV+), use the dedicated button inside the player instead of "Screen Mirroring." It looks like a rectangle with a triangle at the bottom. This will allow you to play the video at maximum quality while you use your phone for other tasks, such as replying to a message or checking email.
⚠️ Attention: When using Screen Mirroring, audio is also transmitted to the TV. If you want to listen to audio through headphones connected to your iPhone while watching video on your TV, this may cause desyncing or may not work on some TV models. It's better to use the native Cast/AirPlay buttons within apps.
Setting up broadcasting on Samsung and LG TVs
Samsung and LG are the Smart TV market leaders, and their approaches to iOS integration are unique. Owners of these TVs often use proprietary apps or built-in services to enhance compatibility.
For TVs Samsung (2018 models and newer) AirPlay 2 support is built into the Tizen operating system. However, for older models that don't support AirPlay, the company offers an app Smart ViewAlthough there is no official iOS app, many users successfully use third-party solutions or Samsung's built-in browser to access their media library.
Televisions LG WebOS-based devices also have built-in AirPlay 2 support. If you have an older model, you can use the app LG TV Plus or TV RemoteThese programs allow you to control your TV and transfer photos and videos from your phone to the big screen via a local network.
Let's look at the main differences in manufacturers' approaches to connecting an iPhone:
| Characteristic | Samsung (Tizen OS) | LG (WebOS) | Android TV (Sony, Philips) |
|---|---|---|---|
| Native AirPlay 2 | Yes (2018+ models) | Yes (WebOS 4.0+) | Yes (Android TV 9.0+) |
| Branded application for iOS | SmartThings (control) | LG ThinQ / TV Plus | Google Home |
| 4K HDR support | Full support | Full support | Depends on the model |
| Lag in Game Mode | Low | Average | High (without Game Mode) |
| Connection stability | High | High | Average |
For older Samsung models where AirPlay is not available, you can try installing the app TV Cast for Samsung TV from the App Store. It works like browser streaming: you open a website with a video within the app, and it sends the stream to your TV via the DLNA protocol.
Third-party streaming apps
If your TV isn't a Smart TV or doesn't support AirPlay, third-party apps can help. They create a software bridge between your iPhone and TV, emulating signal reception protocols. Most of them require installing a dedicated receiver app on your TV (if it's an Android TV) or work via DLNA.
One of the most popular solutions is the application ReplicaIt lets you stream your iPhone screen to TVs that support Chromecast (built-in or external) and AirPlay. The app is paid, but offers a trial period and stable functionality without unnecessary bloat.
For Android TVs (Sony, Philips, Xiaomi, TCL) the app is perfect Cast to TV - XCast or Web Video CasterThey work by scanning the network, searching for available devices, and then sending media content. Video files stored on the phone's memory can also be transferred through these programs.
- 📺 Web Video CasterIdeal for watching videos from your browser. You open a movie site in the app's built-in browser, and it streams the video to your TV, eliminating the need to cast your entire smartphone screen.
- 📷 PhotoCastA specialized photo display app. It allows you to create slideshows from your iPhone albums and display them on your TV with a variety of transition effects.
- 🎮 ApowerMirrorA powerful tool for gamers and others. It not only allows you to mirror your screen but also control your phone from your TV (if a keyboard/mouse is connected), although this requires a more complex setup.
When using third-party apps, it's important to consider network load. Since data is often encoded and transmitted in real time, a weak Wi-Fi signal can result in choppy video or out-of-sync audio and video.
Connection problems and their solutions
Even with proper setup, users may encounter difficulties. The most common issue is that the TV doesn't appear in the list of available AirPlay devices. First, check that Bluetooth is enabled on your iPhone. Although the connection is transmitted over Wi-Fi, the AirPlay protocol uses Bluetooth for initial device discovery and handshake.
The second common cause is using different router frequency bands. If your TV is connected to a 2.4 GHz network and your iPhone is on a 5 GHz network (or vice versa), they may not "see" each other due to isolation settings on the router. Try switching both devices to the same frequency.
It's also worth paying attention to your antivirus or firewall settings if they're installed on your router or local network. They may be blocking ports needed for multimedia traffic.
☑️ Connection diagnostics
If all else fails, perform a full reset of the network: turn off the TV (unplug it for 10 seconds), restart your iPhone, and reboot your router. This will clear the network settings cache and often resolve the "invisibility" issue.
⚠️ Attention: Don't use the "Guest Network" mode on your router to connect smart home devices. In this mode, data exchange between clients is typically blocked by the provider's security settings, making AirPlay and DLNA unavailable.
Using HDMI adapters as an alternative
Wireless data transfer doesn't always guarantee perfect quality, especially in noisy environments or when minimal latency is required (for example, in games). In such cases, wired solutions come to the rescue. Apple offers an official adapter. Lightning to Digital AV Adapter (or USB-C for new iPad and iPhone 15/16 models).
Connecting via cable ensures full-resolution signal transmission (up to 1080p or 4K, depending on the adapter) without compression or artifacts. This method also allows the device to be charged while in use, which is crucial for long presentations or movie marathons.
There are also third-party adapters, which are often cheaper than the original ones. However, be careful when choosing them: cheap copies may not support HDCP (copy protection), causing the screen to be black while audio continues to play when playing videos from Netflix or Apple TV+.
To connect, simply insert the adapter into the iPhone's charging port, connect the HDMI cable from the adapter to the TV, and switch the signal source on the TV to the appropriate port. HDMI.
Why can't my iPhone see my Samsung TV?
Most often, the problem stems from different Wi-Fi networks. Make sure both devices are connected to the same network (not a guest network). Also, check if your TV's firmware needs a firmware update. On Samsung models from 2018 and newer, AirPlay 2 is enabled in the "General" → "Apple AirPlay Settings" menu.
Is it possible to broadcast audio only to the TV and turn off the video?
Yes, this is possible using apps that support AirPlay (YouTube, Spotify, Apple Music). Tap the AirPlay button in the app and select the TV. The phone screen can then be locked or used for other tasks while the audio is transmitted through the TV's audio system.
Video is lagging when streaming from an iPhone. What should I do?
Try reducing network load: disable downloads on other devices. If you use Screen Mirroring, try launching a video using the AirPlay button within the app itself (YouTube, Kinopoisk) rather than mirroring the entire screen. This will reduce the load on your phone's processor.
Does my old TV support AirPlay?
AirPlay is natively supported by TVs released around 2018-2019 (Samsung, LG, Sony, Vizio). Older models require connecting an external set-top box (Apple TV, Chromecast with Google TV) or using USB adapters with Miracast/AirPin support, although the latter often performs poorly with iOS.
How to improve picture quality during wireless broadcasting?
Use the 5 GHz Wi-Fi band; it's less noisy and provides better throughput. Make sure the router is within line of sight of your TV and phone. Avoid placing metal obstacles between devices.
