How to watch a movie from your iPhone on your TV via Wi-Fi: all the working methods

Broadcasting the film from iPhone on the big TV screen through Wi-Fi — a problem that every second equipment owner faces AppleIt would seem that nothing could be simpler: turn it on AirPlay, you choose a TV—and watch your favorite series on a 55-inch screen. But in practice, users encounter lag, no sound, or even a completely invisible TV in the device list. Why does this happen?

The fact is that wireless video transmission depends on a whole range of factors: firmware versions on iPhone and TV, Wi-Fi standard (5 GHz vs 2.4 GHz), codecs in the movie file and even distances between devices. For example, iPhone 15 Pro With iOS 17.4 can broadcast without problems 4K HDR on Samsung QLED 2023, but the same file will slow down LG NanoCell 2020 due to hardware limitations. And that's not to mention the pitfalls like DRM protection in films from Apple TV+ or Netflix.

In this article we will look at all current methods broadcasts from iPhone on TV via Wi-Fi - from standard AirPlay to little-known functions like Screen Mirroring through Google TVWe'll also find out why audio sometimes lags and how to fix video tearing. Spoiler: in 80% of cases, the problem isn't with the TV, but with the router settings.

1. Method #1: AirPlay – the standard method for the Apple ecosystem

AirPlay - this is a proprietary technology Apple, which allows you to broadcast content from iPhone, iPad or Mac to compatible devices. In theory, it's simple: both gadgets must be connected to the same Wi-Fi network, and the TV must support AirPlay 2 (See the list of models below.) In practice, users encounter problems with the TV not appearing in the device list or with streaming constantly interrupted.

To avoid problems, please check the following points:

• 🔄 Software updates: on iPhone the latest version must be installed iOS, and the TV will be updated to the latest firmware (for example, for Samsung This Tizen 7.0+).
• 📶 Wi-Fi network: Both devices must be on the same network. If you have a dual-band router, prioritize the network. 5 GHz - It is more stable for video streaming.
• 🔒 Firewall: on some routers (for example, TP-Link or ASUS) the protocol may be blocked mDNS, which is used AirPlay. Turn it off. AP Isolation in the router settings.

If everything is set up correctly, the broadcast starts like this:

1. Open the movie in an app (eg. Apple TV or Photo).
2. Tap on the icon AirPlay (rectangle with a triangle at the bottom).
3. Select your TV from the list.
4. If required, enter the confirmation code that appears on the TV screen.

Important: DRM-protected movies (such as those purchased from iTunes or rented from Apple TV+) may block streaming to some TV models, even if they support AirPlay. In this case, only an HDMI adapter will help.

Both devices are on the same Wi-Fi network

2. Method #2: Smart View (for Samsung TVs)

If you have a TV Samsung (2018 models and newer), then instead AirPlay you can use proprietary technology Smart ViewIt works faster and more stable, especially with high-resolution files. The main difference from AirPlay — Smart View does not require support from outside Apple, so it is less dependent on updates iOS.

Connection instructions:

1. On TV Samsung open Settings → General → Apple AirPlay and HomeKit and enable the option.
2. On iPhone swipe down to open Control center (or up for models with a Home button).
3. Tap on the icon Screen Mirroring (two rectangles one inside the other).
4. Select your TV Samsung from the list.

Advantages Smart View:

• 🎮 Gamepad support: You can play mobile games on a big screen with minimal lag.
• 📱 Works even if on iPhone Bluetooth is disabled (unlike AirPlay).
• 🔊 Ability to separately broadcast audio to speakers or headphones.

However, there are also limitations:

• ❌ Not all video formats are supported (for example, MKV With DTS- sound may not be reproduced).
• ❌ On some models Samsung 2019–2020, a sound delay of up to 0.5 seconds occurs.

3. Method #3: Google Cast (Chromecast) for Android TV and Google TV

If your TV is running on Android TV or Google TV (For example, Sony Bravia, Xiaomi Mi TV, NVIDIA Shield), then you can use technology Google CastYou don't need a physical one for this. Chromecast — the built-in support in the TV is sufficient.

How does this work:

1. Make sure that and iPhone, and the TV are connected to the same Wi-Fi network.
2. Open an app that supports Google Cast (For example, YouTube, Netflix, Google Photos).
3. Tap the broadcast icon (rectangle with waves in the corner) and select your TV.

List of supported applications Google Cast:

The main advantage of this method is low latency compared to AirPlayHowever, there are some nuances:

• 🚫 Not all applications from App Store support Google Cast (For example, Apple TV+ or Amazon Prime Video they don't have it).
• 🔌 On some routers (especially with firmware OpenWRT) you may need to enable the option IGMP Snooping.

Why is Google Cast better than AirPlay for YouTube?

When streaming via Google Cast, the video is streamed directly from YouTube servers to the TV, and the iPhone is used only as a remote control. This reduces the load on the phone and reduces lag. With AirPlay, the video is first decoded on the iPhone and then transmitted to the TV, which can cause delays.

4. Method #4: DLNA/UPnP – a universal protocol for local files

If you need to broadcast local files (for example, films in the format MP4 or MKV, downloaded on iPhone), then the best option is to use the protocol DLNAIt works on most modern TVs (LG, Sony, Philips) and does not require installation of additional applications on TV.

To do this you will need:

1. Install on iPhone DLNA server. Best options:
   • VLC for Mobile (free, supports all formats).
   • Infuse (paid, but with better support) DTS And Dolby Vision).

Enable DLNA on your TV (usually in the Network → DLNA or Media server).

In the application on iPhone select a file and send it to TV.

Advantages DLNA:

• 🎬 Support for almost all video formats (including MKV, AVI, FLAC).
• 🔗 No ecosystem lock (works even on older TVs from 2015–2017).
• 📁 You can stream entire folders of movies.

Flaws:

• ⚠️ No support DRM - protected films (for example, from Apple TV+) will not be reproduced.
• 🐢 On weak routers (for example, from a provider), buffering may occur.

5. Method #5: Screen Mirroring via Third-Party Apps

If the built-in methods do not work (for example, you have an old TV without AirPlay or DLNA), you can use third-party screen mirroring apps. The most reliable ones are:

• 🔹 ApowerMirror - supports 4K, but requires installation of the server part on a PC or TV.
• 🔹 LetsView - free, but with watermarks in the free version.
• 🔹 TeamViewer QuickSupport - unexpectedly, but it works for mirroring on some models LG.

How to set up ApowerMirror:

1. Download the app on iPhone and on TV (if there is one) Android TV) or on a PC connected to the TV via HDMI.
2. Launch the server part on your TV/PC and select the mode Phone Screen Mirroring.
3. On iPhone Connect to the same Wi-Fi and select a device to stream to.

Important nuances:

• 🛑 When mirroring via third-party applications sound may not be transmitted — it will have to be output separately to a speaker or TV via Bluetooth.
• 🕒 Image lag can reach 1–2 seconds (critical for games, but not for movies).

6. Method #6: Direct connection via Wi-Fi Direct (without a router)

If you don't have a router or your Wi-Fi is unstable, you can use the technology Wi-Fi DirectIt allows you to connect iPhone and your TV directly, without intermediaries. However, this method doesn't work on all TV models and requires additional apps.

Instructions for TVs LG:

1. Open on your TV Settings → Network → Wi-Fi Direct and turn on the function.
2. On iPhone install the application LG TV Plus.
3. In the app, select your TV and connect to its direct network.
4. Start broadcasting via Screen Mirroring V Control center.

Restrictions Wi-Fi Direct:

• 📱 On iPhone This feature only works through third-party applications (unlike Android, where it is built in).
• 📶 The data transfer speed is lower than through a router (maximum 300 Mbps against 866 Mbps on 5 GHz).
• 🔋 Fast battery drain iPhone (due to direct connection).

Wi-Fi Direct It's convenient for temporary broadcasting (for example, at a summer house), but for permanent use it's better to set up a full-fledged network via a router.

Why is Wi-Fi Direct slower than regular Wi-Fi?

With a direct connection, devices use a single channel for data transmission, while a router can distribute the load across multiple channels and frequencies. Furthermore, Wi-Fi Direct lacks the traffic optimization mechanisms found in modern routers.

7. Troubleshooting: lags, no sound, TV not visible in the list

Even if you've set everything up correctly, problems can still arise. Let's look at the most common ones and how to solve them.

Issue 1: TV does not appear in the list of devices for AirPlay/Screen Mirroring

• ✅ Check that the TV is in the "Off" mode. AirPlay (Settings → General → Apple AirPlay).
• ✅ Restart your router—sometimes the DHCP server "forgets" devices.
• ✅ Disable VPN on iPhone - it can block local connections.

Problem 2: Video slows down or breaks

• ✅ Switch to the network 5 GHz (if you use 2.4 GHz).
• ✅ Reduce the channel width in your router settings 80 MHz to 40 MHz - this will reduce the speed, but increase stability.
• ✅ Close background apps on iPhone, especially instant messengers and cloud services.

Problem 3: No sound during broadcast

• ✅ Check if the sound is output to AirPods or column (swipe in Control center and look at the current output device).
• ✅ If you use DLNA, make sure your TV supports the file's audio codec (eg. AC3 or DTS).
• ✅ Reboot iPhone — sometimes the sound driver freezes.

Problem 4: Audio Delay (Lip Sync)

• ✅ Find the option in your TV settings AV Sync or Lipsync and adjust the delay manually.
• ✅ If you are watching through Google Cast, try another player (for example, VLC instead of the standard one).

8. Comparison of methods: which one to choose?

To make it easier for you to decide, we have compiled a comparison table of all the broadcasting methods with iPhone to TV via Wi-Fi.

Recommendations for selection:

• 🎥 For movies from Apple TV+, Netflix or Disney+ better to use AirPlay or Google Cast (depending on the TV).
• 📂 For local files (MKV, MP4) — DLNA through VLC or Infuse.
• 🎮 For games - Smart View (on Samsung) or Google Cast (on Android TV).
• 🏡 For a summer house or temporary use - Wi-Fi Direct.

FAQ: Frequently asked questions about iPhone to TV streaming

Is it possible to stream a movie from an iPhone to a TV without Wi-Fi?

Yes, there are three options:

1. Use Wi-Fi Direct (if the TV supports it).
2. Connect via Lightning/USB-C → HDMI adapter (you need a cable and a free HDMI port on your TV).
3. Use Bluetooth for sound transmission and Screen Mirroring via mobile hotspot (but there will be a strong delay).

The most stable method is an adapter, but it requires a wired connection.

Why does the movie stutter when streaming via AirPlay, but the sound is normal?

This is a typical problem when:

• Weak Wi-Fi signal (check the signal strength in Settings → Wi-Fi on iPhone).
• Congested channel 2.4 GHz (switch to 5 GHz).
• High bitrate video (for example, 4K HDR with a bitrate of 50+ Mbps). Try lowering the resolution to 1080p.

Disabling the function will also help Wi-Fi Assist on iPhone (Settings → Cellular), which automatically switches to mobile Internet when Wi-Fi is weak.

Is it possible to mirror an iPhone's screen to a TV even if they are connected to different networks?

No, for AirPlay, Google Cast And DLNA Both devices must be on the same local network. Exceptions:

• Some routers support the function Guest Network Bridging (combining guest and main networks).
• Apps like ApowerMirror can work via the Internet, but with a strong delay.

For stable broadcasting, always use one network.

How to stream a movie from Safari to TV?

Features vary by site:

• If this is a video from YouTube or Vimeo, open it in the official app and use Google Cast or AirPlay.
• If the video is on a random website, download it to iPhone (for example, through Documents by Readdle) and broadcast via DLNA.
• For online cinemas (for example, Kinopoisk) use their official apps with support AirPlay.

Live streaming of embedded video from Safari on TV is impossible without additional applications.

Why does my TV stop showing up in the AirPlay list after updating iOS?

This is a common problem after major updates (for example, with iOS 16 on iOS 17). Solutions:

1. Update your TV's firmware (for example, for Samsung this is done through Settings → Support → Software Update).
2. Reset network settings on iPhone (Settings → General → Transfer or reset → Reset → Reset network settings).
3. Temporarily disable the firewall on your router (especially if you have ASUS or Keenetic).

If nothing helps, try connecting to the TV via Google Cast (if supported).
