Modern LG TVs running the webOS operating system offer users unlimited multimedia interaction options. One of the most popular use cases is wirelessly transmitting images or videos from a smartphone screen to a larger display. This process, known as synchronization or screencasting, allows you to transform a simple photo gallery or YouTube viewing into a true home theater experience. Today's wireless connection quality allows you to stream high-definition content without any noticeable delays.
For the procedure to be successful, both devices must be in the same information space. This means that your Android or iPhone must be connected to the same local network as LG TVIn most cases, the router automatically assigns IP addresses correctly, but sometimes manual configuration of security settings or Wi-Fi frequency ranges is required. Understanding the basic principles of a home network will significantly simplify the setup process and help avoid common mistakes.
There are several proven methods for achieving this goal, each with its own technical features and advantages. You can use built-in operating system features, proprietary apps from the TV manufacturer, or third-party streaming software. The choice of a specific method depends on your device model, TV firmware version, and personal preferences regarding functionality. Below, we'll examine each available option in detail.
Technical requirements and equipment preparation
Before you begin setup, you need to make sure your equipment meets the minimum technical requirements. Modern LG TVs support the following standards: Wi-Fi Direct and DLNA media transfer protocols, but older models may have limitations. Make sure the wireless module in your TV is working properly and is enabled in the settings menu. To check the connection status, go to Settings → Network → Wi-Fi Connection.
The second critical component is the router. For stable 4K or HDR video streaming, dual-band routers operating at 5 GHz are recommended. The 2.4 GHz frequency may not provide sufficient throughput, resulting in audio and video desynchronization or constant buffering. If your router combines both frequencies under one name (Smart Connect), try temporarily separating them for a more accurate diagnosis.
⚠️ Important: If your router is configured for client isolation (AP Isolation), devices on the network will not be able to see each other. This feature is often enabled on guest networks in hotels or hostels. For home synchronization, client isolation must be disabled in the router settings.
It's also worth paying attention to your TV's software version. LG regularly releases updates for webOS, which improve the stability of wireless connections and add support for new codecs. You can check for updates in the menu. Settings → Support → Software UpdateDon't ignore this step, as outdated firmware may cause incompatibility with new versions of mobile OS.
Your smartphone should also be ready for use: enable location services (required for Android to find devices), ensure Bluetooth is active (used for initial pairing in some protocols), and ensure the battery has sufficient power to keep the screen on for a long time. Energy-efficient modes can block background device search processes, so it's best to disable them during setup.
Using Android's built-in Smart View feature
Owners of smartphones based on Android have access to the native wireless screen mirroring feature. On Samsung devices, this technology is called Smart ViewOn Xiaomi, it's "Broadcast" or "Wireless display," while on other models, it may be hidden under the name "Project" or "Cast." The principle is the same for all: the phone encodes the video stream and transmits it to the TV using the Miracast protocol.
To get started, pull down the notification shade and find the corresponding icon. Once activated, the system will begin searching for available devices within range. When yours appears on the list LG TV, tap it. A connection confirmation prompt may appear on the TV screen. Accept it using the remote control. From now on, the image from your smartphone will be mirrored on the big screen.
- 📱 Open the Quick Settings panel on Android by swiping down from the top.
- 📡 Click on the icon Smart View, "Broadcast" or "Screen Projection".
- 📺 Select your LG TV from the list of devices provided.
- ✅ Confirm the connection on the TV screen if prompted.
It's important to understand the difference between screen mirroring and media streaming. Mirroring displays everything that's happening on your smartphone on your TV, including notifications and the home screen. This is convenient for presentations or demonstrating app interfaces, but it's not always ideal for watching videos, as the phone must keep the screen on constantly, draining battery life.
☑️ Pre-broadcast check
Image quality directly depends on the strength of the Wi-Fi signal. If you observe compression artifacts or image jerkiness, try moving closer to the router or removing any physical obstacles between the transmitter and receiver. It's also a good idea to close background apps on your phone that may consume internet traffic, such as torrents or cloud downloads.
LG TV Plus app for advanced control
Official app LG TV Plus (formerly known as LG Remote) is a universal tool for owners of this brand's TVs. It is available in Google Play And App StoreUnlike simple screen mirroring, this app allows you to use your smartphone as a remote control, enter text using the phone's keypad, and, most importantly, stream photos and videos from your device's gallery directly to your TV.
After installing the app, launch it and follow the on-screen instructions. The program will automatically scan the network and find a compatible TV. To complete the pairing, you will need to enter the code displayed on the TV screen or press the confirmation button on the remote. Once successfully paired, you will have access to the advanced control menu.
The app's functionality isn't limited to the remote control. The "Gallery" or "Media Link" tab allows you to select specific files and send them for playback. The advantage of this method is that the TV decodes the file itself using its powerful processors, reducing the load on the smartphone and often providing better picture quality than simple screencasting.
⚠️ Please note: The LG TV Plus app interface may differ depending on the webOS operating system version (3.0, 4.0, 5.0, 6.0, and higher). Some features, such as cursor control (Magic Mobile), may not be available on very old TV models.
Another useful feature of the app is file transfer. You can quickly send a document or photo from your smartphone to your TV to share with others. This is especially convenient in an office environment or during family gatherings when you need to quickly share content without using USB drives.
What should I do if the app doesn't detect the TV?
If searching for devices in the LG TV Plus app doesn't produce results, check your router's firewall settings. Sometimes antivirus software on your phone or router blocks ports needed to detect devices on the local network (usually ports 3000-3010 and 9080). Try temporarily disabling the firewall for diagnostics. Also, make sure mobile device connections are allowed on your TV in the "General" → "External Device Access Menu" menu.
Stream from iPhone and iPad (AirPlay 2)
Ecosystem users Apple can take advantage of the technology AirPlay 2, which is built into most modern LG TVs (2019 and newer models, as well as older models with AirPlay support). This native iOS feature requires no additional apps for basic streaming. It provides high stability and excellent picture quality.
To connect, open Control Center on your iPhone (swipe down from the upper-right corner or up from the bottom on models with a home button). Tap the "Screen Mirroring" icon (two rectangles). Select your LG TV from the list. If this is your first time connecting, a four-digit code will appear on the TV screen, which you'll need to enter on your iPhone.
Once connected, your smartphone's screen will be mirrored to your TV. You can flip your phone horizontally, and the image will fill the entire screen. AirPlay 2 also allows you to output audio to external audio systems or sound bars, if they are connected to your TV and support this feature, creating a surround sound experience.
| Characteristic | Android (Smart View) | iOS (AirPlay 2) | LG TV Plus app |
|---|---|---|---|
| Connection type | Miracast / Wi-Fi Direct | Proprietary Apple Protocol | LG's own protocol |
| Video quality | Depends on the signal | High (adaptive) | Depends on the file |
| TV control | No (screen only) | No (screen only) | Full control panel |
| Work in the background | The screen should be lit. | You can collapse it | You can collapse it |
It's important to note that AirPlay 2 requires a sufficiently powerful router. If the network is congested, the system may automatically reduce the video resolution to prevent connection interruptions. Ensure your router supports IEEE 802.11ac (Wi-Fi 5) or ax (Wi-Fi 6) for the best experience.
Streaming video from browsers and apps
The most popular use case for synchronization is viewing video content from online services. Applications YouTube, Netflix, Okko and others have a built-in "Cast" feature. Unlike screen mirroring, this method works differently: the phone only sends the TV a link to the video stream, and the TV downloads and plays the video itself via its internet connection.
This means that after starting a video, you can minimize the app, answer a call, or even turn off your smartphone's screen—playback on your TV will continue. To activate it, find the rectangle icon with Wi-Fi waves in the corner in the app. Tap it and select your LG TV. The video will instantly start playing on the big screen.
The advantage of this approach is that it saves battery power and reduces processor load. Furthermore, video quality is often higher, as the TV directly accesses the video service's servers using its network adapter. However, this method requires that the TV have internet access, not just be on the local network.
- 🎥 Open the YouTube or Netflix app on your smartphone.
- 📡 Click the Cast icon in the corner of the video.
- 📺 Select your LG TV from the list of available devices.
- ▶️ Control playback (pause, volume) from your phone.
If the cast button doesn't appear, make sure the apps on your phone and TV are updated to the latest versions. Restarting your router can sometimes help, as the Discovery feature relies on multicast DNS, which can fail after extended network operation.
Diagnosing problems and troubleshooting
Despite the simplicity of the technology, users often encounter problems with synchronization. The most common one is "Device not found." In 90% of cases, the cause is that the phone and TV are connected to different networks. For example, one device is connected to the primary network. Home_WiFi, and another on the guest Home_Guest or at 5 GHz, while the router isolates the ranges.
Another common issue is slow data transfer speeds, manifested by "squares" on the screen or constant buffering. This can be caused by interference from nearby Wi-Fi networks, microwave ovens, or Bluetooth devices. Try changing the router's broadcast channel through its admin panel or moving the router to a more open location.
⚠️ Note: If you use a VPN on your smartphone, local device detection may not work. A VPN reroutes traffic through remote servers, hiding your phone from the local network. Temporarily disable the VPN to sync.
In some cases, resetting the network settings on your TV can help. To do this, go to Settings → General → Network → Wi-Fi Connection, select your network and click "Delete" or "Forget Network," then reconnect by entering the password. This will clear the network connection cache and may resolve the IP address conflict.
If all else fails, try a static IP. Go to the network settings on your TV, disable "Automatic Configuration," and enter the IP address manually, making sure it's in the same subnet as your phone (for example, if your phone's IP is 192.168.1.5, set your TV's IP to 192.168.1.50). This will eliminate any errors from the router's DHCP server.
Why does the phone see the TV, but the connection is reset?
This is often caused by energy-saving modes on your router or antivirus software. An outdated Wi-Fi driver on your TV could also be the cause. Try updating your TV's firmware through the support menu.
Is it possible to connect a phone to an LG TV without Wi-Fi?
Wireless connection is not possible without a Wi-Fi module (either Direct or via a router). However, you can use a wired connection via a USB cable (for photo/video files) or an HDMI adapter (USB-C to HDMI / Lightning to HDMI).
The sound is delayed during synchronization, what should I do?
Audio lag is a common issue with the Miracast protocol. Try enabling "Game" mode in your TV settings or disabling additional image processing (such as Noise Reduction or Smooth Motion). This will reduce frame processing time.
Does my old LG TV support Smart View?
Smart View (Miracast) technology is supported by most LG Smart TVs released after 2014. Older ("Non-Smart") models require a separate adapter (such as a Chromecast or Miracast dongle) that plugs into the HDMI port.
How to improve picture quality during broadcasting?
Make sure the content on your phone is already in high quality. When mirroring, the resolution is often limited to 720p or 1080p to reduce latency. For 4K, use built-in apps on your TV (YouTube TV, Netflix TV) rather than streaming from your phone.
