How to connect your phone to an LG TV via Wi-Fi: all the methods + troubleshooting

Wirelessly connect your phone to your TV LG via Wi-Fi opens up a lot of possibilities: from streaming movies with YouTube to the big screen to display vacation photos in high resolution. However, many users encounter problems—the TV doesn't recognize the phone, the image lags, or the sound cuts out. In this article, we'll look into all current connection methods (including hidden functions LG Smart TV), we will compare them in terms of speed and stability, and also provide a checklist for eliminating typical errors.

It is important to understand that the connection method depends on the TV and smartphone model. For example, older LG (before 2017) may not support Miracast, but they have their own protocol LG Smart Share. And modern flagships (series OLED C2, QNED) offer several options at once - from Google Cast to the branded one Screen ShareWe'll look at universal solutions that work on 90% of devices, as well as highlight the nuances for specific models.

If you've already tried connecting and it didn't work, don't rush to blame the technology. In 70% of cases, the problem lies in incorrect router settings (for example, splitting the network into 2.4 and 5 GHz) or outdated firmware TV. We've created a separate section on diagnosing such cases.

1. Preparing your LG TV and phone for connection

Before connecting devices, make sure they meet the minimum requirements:

• 📺 LG TV with support Wi-Fi Direct, Miracast or DLNA (almost all models after 2014). You can check in the menu Settings → Network → Wi-Fi.
• 📱 Smartphone on Android 5.0+ or iOS 12+ (For AirPlay will be needed iPhone 6s or newer).
• 📶 Router with standard support 802.11n (or higher) and frequencies 2.4 GHz/5 GHzFor stable streaming, the recommended speed is 10 Mbps.
• 🔄 Both devices must be connected to one Wi-Fi network (exception - Wi-Fi Direct, where the network is created by the TV itself).

Pay special attention TV firmwareOutdated software often causes connection problems. To update LG Smart TV:

1. Open Settings → Support → Software Update.
2. Select Check for updates and follow the instructions on the screen.
3. If the update is not found, download it manually from the website. LG (specify the exact TV model) and download via USB.

Also check your router settings:

• 🔒 Turn it off guest access to Wi-Fi - it can block communication between devices.
• 🔄 Make sure that AP Isolation (client isolation) is turned off - otherwise the phone and TV will not see each other.
• 📡 If your router is dual-band, connect both devices to one frequency (better 5 GHz for smaller delays).

2. Method 1: Screen Share (Miracast) – screen mirroring without lags

Screen Share (in some models - Miracast) is a technology that allows broadcast your phone's screen to your TV in real time with minimal latencyIt's ideal for games, videos, and presentations where image and sound synchronization is important. However, it doesn't work on all smartphones: for example, iPhone does not support Miracast (they need AirPlay), and some are budget Android- devices may not have this feature.

Instructions for Android:

1. On TV LG open Settings → Connection → Screen Share (or Screen mirroring).
2. Turn on your phone Miracast:
   • For Samsung: Settings → Connections → Image Transfer → Screen Mirroring.
   • For Xiaomi/Redmi: Settings → Connection and Sharing → Screen Sharing.
   • For clean Android: Settings → Display → Wireless.

Select your TV from the list of available devices. LG (the name will be something like LG_OLED55C1).

Confirm the connection on both devices.

If the image slows down or breaks:

• 📉 Reduce your phone's screen resolution in settings Miracast (if there is such an option).
• 🔌 Connect your phone to a charger - when the battery level is low, the system may limit performance.
• 📶 Switch to frequency 5 GHz in the router settings (if the TV and phone support it).

3. Method 2: Smart Share (DLNA) – viewing media files without screen mirroring

DLNA (or LG Smart Share) is a protocol for transmission media files (video, music, photos) from phone to TV without duplicating the entire screenUnlike MiracastThere's no latency, but the functionality is limited: you can't stream games or apps, only content from your gallery.

How to connect:

1. On TV LG open the application Smart Share (or Media player → DLNA).
2. On the phone Android use the standard application Gallery or Files:
   • Select a file (video, photo, audio).
   • Click Share → DLNA or Transfer to device.
   • Select your TV from the list. LG.

For iPhone download the app LG TV Plus or AllConnect from App Store.

Advantages DLNA:

• ✅ No delay in video playback.
• ✅ Works even on older TVs LG (since 2012).
• ✅ Supports formats MKV, MP4, FLAC (if the TV "understands" them).

Flaws:

• ❌ You can't broadcast your entire screen (only individual files).
• ❌ Not all applications (for example, Netflix or YouTube) support transmission via DLNA.

What video formats does DLNA support on LG TV?

Most LG TVs play via DLNA:

- Video: MP4 (H.264), AVI (Xvid), MKV (up to 1080p)

- Audio: MP3, AAC, WAV, FLAC (on models since 2018)

- Photos: JPEG, PNG, BMP

Restrictions: 4K video may not play on TVs until 2016, and DRM-protected content (such as from Disney+) will not stream.

4. Method 3: Wi-Fi Direct – direct connection without a router

Wi-Fi Direct allows you to connect your phone and TV LG Directly, without a router. This is convenient if you don't have Wi-Fi at home or want to save on mobile data. However, this method has its caveats:

• 🔄 The TV creates its own access point, which the phone connects to. This means that The internet on the phone won't work (if not enabled Modem mode).
• 📱 Not all smartphones support Wi-Fi Direct in client mode (especially iPhone).
• 🎮 Broadcast latency may be higher than through a router.

Step-by-step instructions:

1. On TV LG go to Settings → Network → Wi-Fi Direct and turn on the function.
2. On the phone Android open Settings → Wi-Fi → Wi-Fi Direct (or More → Wi-Fi Direct).
3. In the list, find the name of your TV (for example, DIRECT-LG_WebOS) and connect.
4. Confirm the connection on both devices (you may be asked to enter a PIN).
5. Now you can use Screen Share or Smart Share as usual.

If the phone does not see the TV in Wi-Fi Direct:

• 🔄 Restart both devices.
• 📱 Turn it off on your phone Adaptive Wi-Fi (in wireless network settings).
• 🔧 Reset network settings on your TV: Settings → Network → Network Reset.

5. Method 4: Streaming apps (YouTube, Netflix, browser)

Many applications (eg. YouTube, Netflix, IVI) have a built-in TV broadcast function. This is often easier than setting up Miracast or DLNA, as it does not require additional settings - it is enough that both devices are on the same network.

How to stream from YouTube:

1. Open the video in the app YouTube on the phone.
2. Click on the icon Broadcast (in the upper right corner).
3. Select your TV from the list. LG (should appear automatically).
4. The video will start playing on the TV, and you can use your phone to control it (pause, volume).

Broadcasting from: works similarly.

• 🎬 Netflix, Kinopoisk, IVI (icon Cast in the upper right corner).
• 🌐 Google Chrome (menu Three dots → Broadcast).
• 📷 Google Photos (open photo → Share → Broadcast).

If your TV does not appear in the list of devices for streaming:

• 🔄 Make sure your TV is turned on LG Content Store (sometimes it blocks external connections).
• 📱 Update the application on your phone (for example, YouTube).
• 🔧 Reboot your router—sometimes it distributes multicast traffic incorrectly.

6. Troubleshooting: Phone won't connect to LG TV

If none of the above worked, use our diagnostic table:

If the problem persists, try resetting the network settings on your TV:

1. Go to Settings → Network → Network Reset.
2. Reconnect to Wi-Fi.

What should I do if the broadcast stops working after updating the firmware?

Reset your TV to factory settings (Settings → General → Reset settings), but before doing this, write down your image and sound settings. Also, check if the function has been disabled. Screen Share in the new settings (sometimes it resets after an update).

7. Alternative connection methods (if Wi-Fi doesn't work)

If you are fundamentally unable to set up a wireless connection, consider alternatives:

• 🔌 HDMI cable with an adapter (for example, USB-C to HDMI (For modern smartphones). Suitable for stable, lag-free streaming, but requires a physical connection.
• 📶 Bluetooth — only for transmitting audio (for example, music). On the TV, turn on Settings → Sound → Bluetooth device.
• 💽 USB drive — Copy the files to a flash drive and connect it to the TV. The following formats are supported MP4, MKV, JPEG.
• 📡 Chromecast or Apple TV - external devices for broadcasting, if built-in functions LG don't work.

For HDMI connections you will need:

• Adapter (eg. USB-C to HDMI For Samsung Galaxy or iPhone 15).
• Cable HDMI 2.0 (for support 4K@60Hz).
• Turn on the mode on your phone HDMI or DeX (For Samsung).

8. Optimize Wi-Fi for stable streaming

Wi-Fi streaming quality depends not only on your devices but also on your network settings. Here's how to improve your connection:

• 📡 Wi-Fi channel: Use less crowded channels (eg. 149 or 161 on 5 GHz). You can check the workload in the app. Wi-Fi Analyzer.
• 🔄 Channel width: install 40 MHz For 5 GHz (in the router settings).
• 🛡️ Security: use WPA2-AES (Not TKIP), since the latter slows down the connection.
• 📦 QoS: turn on Quality of Service on the router and set maximum priority for the TV and phone.

For routers TP-Link:

1. Go to the control panel at 192.168.0.1 (or 192.168.1.1).
2. Go to Wireless → Wireless Settings.
3. Set the channel manually (eg. 36 For 5 GHz).
4. Save the settings and reboot the router.

If you have mesh system (For example, Google Nest Wi-Fi or TP-Link Deco), make sure your phone and TV are connected to one node network. Otherwise, the delay can reach 500 ms.
