How to stream a movie from your phone to an LG TV via Wi-Fi: all the working methods

Wirelessly stream movies from your phone to your big-screen TV LG saves time on connecting cables and opens up new possibilities for viewing content. However, not all users know that for stable video transmission over Wi-Fi Not only compatible equipment is required, but also the correct network settings. In this article, we'll cover all the current streaming methods—from built-in functions Smart Share to universal protocols Miracast And Google Cast, and we will also explain why image delays or sound interruptions sometimes occur.

Feature of TVs LG (series OLED, NanoCell, QNED and budgetary UK6x/UN7x) is to support multiple wireless transmission protocols simultaneously. This means you can choose the optimal method depending on your smartphone model (Android or iPhone), operating system versions (webOS 4.0–23) and even on the video format (for example, 4K HDR (Requires a more stable connection). We tested all methods on real devices and highlighted their pros and cons in the comparison table below.

If you've encountered streaming issues before—for example, the TV doesn't see your phone in the list of available devices or the video is lagging—there's a section at the end of this article with troubleshooting common errors. You'll also find tips on configuring your router to minimize lag.

1. Preparing your LG TV for wireless broadcasting

Before you can stream a movie from your phone, you need to activate the corresponding functions on the TV itself. For models LG With webOS (2018 and newer) this process takes no more than 2-3 minutes, but there are some nuances for older firmware versions.

First, check that your TV and phone are connected. one Wi-Fi networkThis is a mandatory requirement for most broadcast methods (except Wi-Fi Direct). If you are using a dual-band router (2.4 and 5 GHz), make sure both devices are in one frequency band — otherwise they won't see each other. The best option for video transmission is a network connection. 5 GHz, as it provides lower latency.

Next, enable the function Smart Share (or Screen Share in new models):

1. On the remote control LG press the button Home (home).
2. Go to Settings → All settings → Network → Miracast/Wi-Fi Direct.
3. Activate the switch Screen Share or Wi-Fi Direct.
4. In some models (webOS 3.5 and older) may require additional confirmation via a PIN code that will be displayed on the screen.

For TVs LG 2017 and older (from webOS 3.0–3.5) the path to the settings may differ: Settings → Network → Devices → Wi-Fi DirectIf there is no item in the menu Miracast, update your TV firmware via Settings → General → About TV → Software Update.

2. Cast from Android phone to LG TV

Smartphone owners on Android 5.0 and newer can use three main methods of video transmission: Wi-Fi Direct, Miracast And Google CastLet's look at each of them, taking into account the firmware features. LG.

2.1 Method 1: Wi-Fi Direct (direct connection)

This is the most reliable method for older TV models (webOS 2.0–3.5), since it does not require connection to a router. Wi-Fi Direct creates a direct connection between the phone and TV, which reduces latency but limits internet access on the smartphone during broadcasting.

Instructions for Android:

1. On TV LG activate Wi-Fi Direct (see section 1).
2. Open it on your phone Settings → Connections → Wi-Fi.
3. Click Wi-Fi Direct (or More → Wi-Fi Direct on Samsung).
4. From the list of available devices, select the name of your TV (for example, LG_OLED55C1).
5. Confirm the connection on both devices (you may be asked to enter a PIN).

Once connected, open any video player (for example, VLC or MX Player) and select the option Play on another device or Cast. In some players (for example, in the standard Google Photos) you need to click on the broadcast icon (rectangle with waves) and select the connected TV.

Phone and TV within range of each other (up to 10 m)

The TV is in the "Standby" mode. Screen Share

The Wi-Fi power saving mode is disabled on the phone.

The video file supports hardware decoding (for example, H.264 or H.265)

2.2 Method 2: Miracast (screen mirroring)

Miracast Allows you to fully mirror your smartphone's screen to your TV, including sound. This method is suitable for watching movies in any apps (including Netflix, YouTube or KinoPoisk), but may introduce a delay of up to 1–2 seconds due to real-time video encoding.

How to enable Miracast on Android:

1. On TV LG activate Screen Share (path: Settings → Network → Miracast).
2. Open it on your phone Settings → Display → Wireless Display (on Samsung it could be Smart View, on Xiaomi — Wireless Display).
3. Find your TV in the list. LG and connect to it.
4. Confirm the connection on TV (you may be asked to allow mirroring).

Once connected, your phone's entire screen will be displayed on your TV. To avoid draining your battery, please connect your smartphone to a charger. Please note: some apps (e.g., Netflix) block the broadcast through Miracast due to content protection DRMIn this case, use Google Cast (see method 3).

Why might Miracast not work?

If your TV does not appear in the list of devices, check:

1) Does your smartphone support Miracast (on some budget models this function is disabled).

2) Is the TV firmware updated (on webOS 3.0 and below Miracast (works unstably).

3) Is the power saving mode enabled on your phone, which disables background processes?

2.3. Method 3: Google Cast (Chromecast)

Protocol Google Cast (built in YouTube, Netflix, Google Photos and other apps) allows you to stream content directly from your phone to your TV without duplicating the entire screen. The main advantage is minimal latency and support 4K HDR on compatible models LG (series C1, G1 and newer).

How to broadcast via Google Cast:

1. Make sure your phone and TV are connected to the same Wi-Fi network.
2. Open a supported application (eg. YouTube).
3. Click on the broadcast icon (rectangle with waves in the upper right corner).
4. Select your TV from the list. LG (it should show up as LG_XXXX [TV]).
5. Start playing the video and it will start broadcasting on TV.

If the broadcast icon is not active, check:

• 🔹 Does your app support Google Cast (full list: Google's official website).
• 🔹 Is the TV in standby mode? Google Cast (Settings → General → Devices → Google Cast).
• 🔹 Does the router block multicast traffic (it should be enabled in the router settings) IGMP Snooping).

3. Stream from iPhone to LG TV (AirPlay and alternatives)

Owners iPhone or iPad face restrictions when broadcasting to TVs LG, because AirPlay (minutes from Apple) is supported by default only on models LG 2019 and newer (from webOS 4.5+). Older TVs will require workarounds.

3.1 Method 1: Built-in AirPlay (for new LG models)

Televisions LG series OLED (2019–2023), NanoCell (2020–2023) and QNED (2021–2023) have built-in support AirPlay 2This allows you to stream videos, music, and even mirror your screen. iPhone without additional devices.

How to enable AirPlay on LG TV:

2. Activate the switch AirPlay.
3. On iPhone open Control center (swipe down from the top right corner).
4. Click Screen mirroring and select your TV LG from the list.

To broadcast a specific video (for example, from Apple TV+ or YouTube):

1. Open the video in the app.
2. Click on the icon AirPlay (rectangle with a triangle at the bottom).
3. Select your TV LG.

If your TV does not appear in the list, check:

• 🔹 TV and iPhone connected to the same Wi-Fi network (preferably 5 GHz).
• 🔹 The TV is in standby mode AirPlay and turned off Power saving mode.
• 🔹 On iPhone The firmware has been updated (minimum version - iOS 12.3).

3.2 Method 2: Proxy apps for older LG models

If your TV LG released before 2019, AirPlay won't work directly. In this case, use third-party applications such as ApowerMirror, LetsView or Screen MirroringThey create a virtual bridge between iPhone and TV via Wi-Fi.

Instructions for ApowerMirror:

1. Install the application ApowerMirror on iPhone and a computer (or use the web version).
2. On TV LG open your browser and go to the website apowermirror.com, then scan the QR code from the screen iPhone.
3. Click Start Mirroring on the phone.

Disadvantages of this method:

• 🔸 Image delay up to 2-3 seconds.
• 🔸 A stable internet connection is required.
• 🔸 Video quality may be reduced to 720p.

4. Comparison of broadcast methods: which one to choose?

To determine the best way to transfer video from your phone to LG TVWe tested all the described methods on different devices and compiled a comparison table. Please note the columns Delay And Quality - they are critical for comfortable movie viewing.

To watch movies in high definition (4K HDR) with minimal latency, we recommend using Google Cast on Android or AirPlay on iPhone if your LG TV supports these protocols. If you need to stream local video files without internet access, Wi-Fi Direct or Miracast are the best choices.

For streaming services (Netflix, YouTube, OKKO) the priority method is Google Cast, because it supports DRM- protection and adaptive video quality. If you want to mirror your smartphone's entire screen (for example, to show photos or games), use Miracast or AirPlay.

5. Configuring your router for stable streaming

The quality of your Wi-Fi streaming directly depends on your router settings. Even if you've chosen the optimal video transmission method, an unstable connection can cause audio interruptions, image freezes, or even a complete loss of streaming. Let's look at the key parameters to check.

The first thing you should pay attention to is frequency rangeTo broadcast video in resolution 1080p and above it is recommended to use the network 5 GHz, as it's less congested and provides greater throughput. However, it has a shorter range, so if the TV and router are in different rooms, you may have to use 2.4 GHz or install Wi-Fi repeater.

The second important parameter is channel width. In the router settings (section Wi-Fi → Wireless Settings) install:

• 🔹 For 5 GHz: channel width 40 MHz or 80 MHz (if devices support it).
• 🔹 For 2.4 GHz: channel width 20 MHz (reduces interference from neighboring networks).

Also check the following settings:

• 🔹 Wi-Fi operating mode: select 802.11ac (or 802.11ax for new routers) for maximum speed.
• 🔹 Qos (Quality of Service): Enable traffic prioritization for multimedia (optional) WMM or Multimedia Priority).
• 🔹 IGMP Snooping: Please enable for proper operation Google Cast And DLNA.

If you still have problems after changing the settings, try:

1. Reboot the router (turn off the power for 30 seconds).
2. Change the Wi-Fi channel manually (in the router settings, select the least loaded channel using the utility) Wi-Fi Analyzer).
3. Disable the feature Band Steering (if enabled) as it can force switching devices between 2.4 GHz And 5 GHz.

How to check Wi-Fi channel load?

Download the app on Android Wi-Fi Analyzer (or NetSpot for iOS). It will show you which channels are in your range (2.4 GHz or 5 GHz) are less congested. Choose a channel with minimal overlap (ideally, without neighboring networks).

6. Solving typical broadcast problems

Even with the correct settings, users often encounter errors when trying to transfer video from their phone to LG TVWe've compiled the most common problems and how to fix them.

6.1. The TV does not see the phone in the list of devices

If your smartphone is not displayed when you try to connect via Wi-Fi Direct or Miracast, check the following:

• 🔹 Make sure your TV is in the "Off" mode. Screen Share (Settings → Network → Miracast).
• 🔹 Restart both devices (phone and TV).
• 🔹 Turn off the mode on your phone Energy saving And Adaptive brightness - they can block background processes.
• 🔹 If you use Miracast, check phone compatibility: some models Xiaomi And Huawei require the option to be enabled Wireless display V Settings → Advanced.

For iPhone:

• 🔹 Make sure your TV supports AirPlay (models LG (not supported until 2019).
• 🔹 Check that iPhone and the TV are on the same subnet (for example, both have IP addresses of the type 192.168.1.x).

6.2. The video slows down or stops

Image lag and freezing are usually caused by insufficient Wi-Fi bandwidth. To fix the problem:

• 🔹 Switch to the network 5 GHz (if you use 2.4 GHz).
• 🔹 Reduce the video resolution: for example, instead of 4K select 1080p in the player settings.
• 🔹 Close background applications on your phone that consume the Internet (for example, downloads in Telegram or YouTube).
• 🔹 If you use Miracast, try it Google Cast - it is optimized for streaming.

If the problem persists, check your internet speed:

1. Run a speed test on your phone (for example, through Speedtest).
2. If the speed is lower 10 Mbps, broadcast 4K will not be possible - switch to 720p.

6.3. No sound during broadcast

No sound is a common problem when using Miracast or Wi-Fi DirectCauses and solutions:

• 🔹 On TV LG check if the sound is muted (button Mute on the remote control).
• 🔹 In the broadcast settings on your phone, select the option Transmit sound (V Miracast or Screen Mirroring).
• 🔹 If you use Google Cast, make sure that the application supports audio transmission (for example, YouTube or Netflix do it automatically).
• 🔹 For local files, make sure the audio track is in the following format: AAC or MP3 - some TVs LG do not support AC3 (Dolby Digital).

6.4 The TV turns off during the broadcast

If LG TV suddenly loses connection with the phone, the reasons may be the following:

• 🔹 It's on on the TV Power saving mode - turn it off in Settings → General → Power Saving.
• 🔹 The router automatically switches devices between 2.4 GHz And 5 GHz (turn off Band Steering).
• 🔹 The distance between the phone and the TV is too great (optimally up to 5 meters).
• 🔹 Interference from other devices (microwaves, wireless headphones). Try changing the Wi-Fi channel in your router settings.

7. Alternative broadcasting methods (without Wi-Fi)

If wireless methods are not suitable due to unstable connection or device incompatibility, consider alternative options for connecting your phone to LG TVThey require additional accessories, but guarantee stable video transmission without delays.

7.1. HDMI connection (via adapter)

The most reliable way is to use HDMI adapter for the phone. For Android an adapter will fit USB-C to HDMI (or Micro-USB to HDMI for older models), and for iPhone — Lightning to HDMI (official from Apple or certified).
