Modern LG TVs with technology support Smart TV They've evolved from being simple devices for receiving over-the-air channels into powerful multimedia centers. One of the most sought-after features is the ability to wirelessly connect to mobile devices, allowing you to stream photos, videos, and even the entire smartphone screen to a larger screen. LG Smart TV Connecting your phone via Wi-Fi opens access to a huge array of content, making watching movies or presentations much more comfortable.
The synchronization process may vary depending on your device's operating system and TV model. Owners Android And iPhone While these devices use different data transfer protocols, the basic principle remains the same: both devices must be on the same local network. In this article, we'll cover all current connection methods in detail, examine how proprietary apps work, and help resolve common connection issues.
You don't need to be a techie to connect your gadgets. Modern interfaces webOS and mobile OS are designed to be as user-friendly as possible. Simply follow a few steps in the settings menu to start enjoying content on the big screen without the hassle of wires.
Preparatory stage and network testing
Before beginning the active setup phase, you need to ensure your home network infrastructure is ready to handle heavy media content. The first and most critical requirement is that both devices are on the same subnet. This means that both the TV and smartphone must be connected to the same router.
Users often encounter a situation where their router broadcasts two networks: 2.4 GHz and 5 GHz. For stable high-definition video transmission, it's preferable to use the 2.4 GHz band. 5 GHz, as it provides higher throughput. However, if your router doesn't support automatic network aggregation (Smart Connect), make sure both devices are connected to the same SSID.
⚠️ Note: If your router uses Client Isolation mode or a guest network with restricted access to local devices, the TV and phone will not be able to "see" each other, even if they are in the same room.
It's also worth checking your TV's software version. Outdated firmware webOS may not support new encryption protocols or standards MiracastGo to the settings menu and check for updates to eliminate software conflicts early on.
Using the built-in Screen Share feature
Technology Screen Share (based on the Miracast standard) is a native solution for owners of smartphones based on AndroidThis method allows you to mirror your phone's screen to your TV in real time without installing additional software. This feature is already built into most modern models. LG.
To activate standby mode on your TV, go to the signal source menu. Press the button Input on the remote control and select the application Screen Share or Device Connector in the list of running apps. A message will appear on the screen indicating that the TV is ready to connect and is waiting to be searched.
On a smartphone, the algorithm of actions is as follows:
- 📱 Open the notification shade and find the "Cast", "Smart View" or "Screen projection" button.
- 🔍 Wait until the search for available devices within Wi-Fi range is complete.
- ✅ Choose yours LG TV from the list and confirm the connection on the TV screen if an access request appears.
Picture quality when using Miracast Depends directly on the Wi-Fi signal strength. If you notice cursor lag or compression artifacts, try moving closer to the router. It's important to understand that in this mode, the phone isn't simply sending a file; it's encoding the video stream in real time, which requires processor resources.
Connecting an iPhone via AirPlay 2
Equipment owners Apple will appreciate the protocol support AirPlay 2, which appeared on television LG Starting with 2019 models, this technology ensures the highest quality image and sound transmission with minimal latency, and also allows the TV to be used as a separate audio system in a multi-room system.
Unlike other devices, you don't need to run special apps on your TV. Simply enable AirPlay in the settings. webOS. It is usually enabled by default, but you can check it in the section Settings → Connection → AirPlayMake sure the switch status is in the "On" position.
The connection process is as simple as possible and integrated into the system. iOS:
- 🍏 Open Control Center on your iPhone (swipe down from the top-right corner or up from the bottom on older models).
- 📺 Tap the Screen Mirroring button (the icon with two rectangles).
- 📡 Select your TV LG from the list of available devices.
When you first connect, a four-digit code may appear on your TV screen, which you'll need to enter on your iPhone. This is a security measure to prevent unauthorized access to your screen. Once successfully authenticated, your device will remember your code and won't be prompted for it in the future.
⚠️ Note: The AirPlay 2 protocol is sensitive to your router's firewall settings. If your TV isn't visible, check to see if your router is blocking the ports used by the Bonjour (mDNS) protocol.
A special feature of AirPlay is the ability to broadcast not the entire screen, but a specific video from supported applications, such as YouTube, Netflix or Apple TV+In this case, the phone acts only as a remote control, and the video stream goes directly from the server to the TV, which saves battery life.
LG ThinQ Mobile App
For deep integration of the smartphone into the ecosystem LG an official application has been developed LG ThinQIt is available for download in stores. Google Play And App StoreThis app turns your phone into an advanced remote control, allowing you to not only stream media but also control your TV settings.
After installing the application, you need to register or log in to an existing account. LGThen tap the Add Device button. The app will automatically scan the Wi-Fi network and prompt you to add the TV it finds. A confirmation code will appear on the TV screen, which you'll need to enter in the app.
Functional LG ThinQ includes:
- 🖥️ Broadcast photos and videos from your phone gallery to the big screen.
- 🎮 Use your smartphone as a touchpad to navigate webOS menus.
- ⌨️ Enter text using your phone's keyboard (useful for searching YouTube).
A key advantage is the ability to control the TV via mobile internet if both devices are linked to the same account, although a local Wi-Fi network is still required for live media streaming. The app also allows you to create smart home scenarios by linking the TV to other devices. LG.
What should I do if the app doesn't detect the TV?
Make sure the LG ThinQ app has permission to access the local network (this is critical for iOS) and geolocation. Without these permissions, network scanning may be blocked by the OS security system.
Comparison of connection methods and their features
The connection method you choose depends on your goals: whether you need to mirror your screen for a presentation, view vacation photos, or stream a movie from the internet. Each method has its own technical limitations and advantages, which should be considered when using it.
Below is a comparative table of the main characteristics of different connection methods:
| Characteristic | Screen Share (Miracast) | AirPlay 2 | LG ThinQ App |
|---|---|---|---|
| Device type | Android / Windows | iOS / macOS | Android / iOS |
| Image quality | Depends on the signal | High (1080p/4K) | Standard |
| Latency | Average | Minimum | Low |
| Battery consumption | High | Average | Short |
Best suited for gaming or displaying dynamic content AirPlay 2 or a wired connection, since wireless protocols are based on Miracast may introduce a noticeable delay between actions on the phone and the image on the screen. For viewing static photos or slideshows, the difference will be virtually imperceptible.
It is worth noting that some older TV models LG may not support new video encoding standards. In such cases, the application LG ThinQ It can act as a universal converter, albeit with a loss in quality. Always try to use the method most native to your device pair.
Solving common connection problems
Even if you follow all the instructions, situations may arise where devices refuse to connect. Most often, the problem lies in the router's security settings or temporary network protocol glitches. The first step should always be to reboot both devices—this resolves approximately 80% of connection issues.
If the TV is visible but the connection keeps dropping, try changing the DNS settings on the TV itself. Go to Settings → Network → Wi-Fi → Advanced settings and manually enter DNS servers, for example, from Google (8.8.8.8). This often helps if your ISP blocks some local requests.
Another common cause is antivirus software on your computer or smartphone, which can block incoming connections on your local network. Check your firewall settings and ensure your network is classified as "Home" or "Private," not "Public."
⚠️ Note: Menu interfaces and item names may vary slightly depending on the webOS operating system version (3.0, 4.0, 5.0, 6.0, and later). If you don't find an exact match, look for similar sections in the network settings.
If persistent errors occur, it's a good idea to reset the network settings on your TV. This will restore the connection settings to factory defaults and force the device to re-establish a handshake with the router, which often resolves hidden IP address conflicts.

Frequently Asked Questions (FAQ)
Is it possible to connect a phone to an LG TV without Wi-Fi?
Yes, this is possible with a cable. Android typically requires a USB-C to HDMI adapter that supports MHL or DisplayPort Alt Mode. iPhone requires a Lightning to HDMI adapter (or USB-C to HDMI for newer models). In this case, Wi-Fi is bypassed, and the image is transmitted directly via the cable, ensuring no lag.
Why doesn't my LG TV see my phone in the list of devices?
Most likely, the devices are connected to different router frequencies (2.4 GHz and 5 GHz) that are isolated from each other, or the "Guest Network" feature is enabled. Also, check if the router is configured to restrict data exchange between clients (AP Isolation). Make sure a signal-receiving app (such as Screen Share) is running on the TV.
Video is lagging when streaming from my phone to an LG TV. What should I do?
Lag is most often caused by a weak Wi-Fi signal or channel congestion. Try moving closer to the router, disabling downloads on other devices, or switching the router to a less congested channel. Lowering the streaming video resolution in your phone's settings can also help stabilize the stream.
Do all LG Smart TVs support AirPlay?
No, support AirPlay 2 This feature is only available in 2019 and newer models (B9, C9, E9 series and newer, as well as later UM and SM series). Older models may require third-party apps from the Content Store to receive a signal from an iPhone.
