Modern LG Smart TVs offer users a wide range of multimedia experiences. One of the most popular use cases is wirelessly streaming images from a smartphone to a large screen. This allows users to view photos, videos, and even play mobile games, all while enjoying the TV's large display and high-quality sound system. Wi-Fi Direct technology and Miracast protocols make this process as simple and accessible as possible for anyone with compatible equipment.
However, despite the apparent simplicity, users often encounter various setup nuances. Differences in the Android and iOS operating systems, as well as different webOS firmware versions on TVs, can introduce adjustments to the pairing process. Proper home network setup is the foundation for the stable operation of all wireless functions. In this article, we'll cover all connection methods in detail, from built-in tools to third-party apps.
It's important to understand that data transmission quality directly depends on your router's power and signal strength. High-resolution video streaming (4K or Full HD) requires a stable connection without significant interference. If you plan to use this feature frequently, Screen Share, it is recommended to place the router in close proximity to the TV or use a wired connection to the TV itself to reduce the airtime load.
Equipment preparation and compatibility testing
Before setting up, you need to make sure your equipment supports the necessary wireless technologies. Almost all modern LG TVs released after 2012 are equipped with a Wi-Fi module and support the Miracast standard. Smartphones should also have the corresponding features, which are typically built into Android operating systems (version 4.2 and higher) and iOS.
The key to a successful connection is that both devices are on the same local network. This means that both the phone and TV must be connected to the same router. If you have a dual-band router, make sure both devices are connected to the same frequency (either 2.4 GHz or 5 GHz), although in most cases, modern routers automatically manage clients correctly.
- 📱 Check that your smartphone's Wi-Fi module is enabled and active.
- 📺 Make sure your LG TV is connected to the internet and has the latest firmware version.
- 📡 Devices must be connected to the same Wi-Fi network (same SSID).
- 🔋 Charge your smartphone, as active video streaming quickly drains the battery.
It's worth noting that some older router models may not correctly process multicast traffic, which is used to discover devices on the network. In such cases, you may need to reboot the router or update its firmware. Also, make sure the "Client Isolation" feature, which prevents devices on the network from seeing each other, is not enabled on the router.
⚠️ Attention: If your router is broadcasting two networks with the same name for 2.4 GHz and 5 GHz, try temporarily separating them or forcing both devices to connect to the 5 GHz network for better video transfer speeds.
For users of corporate networks or complex home systems with multiple access points, it's important to remember about network segmentation. Devices must be on the same subnet segment (VLAN), otherwise DLNA and Miracast discovery protocols may fail. This is rare in home environments, but with mesh systems, switching between nodes is sometimes necessary.
Setting up an LG TV to receive a signal
Before searching for a TV from your phone, you need to prepare your Smart TV to accept the connection. In the webOS operating system, which is installed on most modern LG models, this feature may have different names depending on the year of manufacture. In newer models, it's often integrated into the "Connect to a mobile device" menu, while in older models, it's a separate app.
To access the TV's main menu, press the house button on the remote. Then, go to Settings or search for the "Screen Share" app. In some interface versions, this app may be called "Mobile Device Connector" or "Device Connector." Once the app launches, the TV will enter connection standby mode.
Menu path: Settings → Connection → Connect to mobile deviceIn the menu that opens, you'll see a list of available options. For a wireless connection, we're interested in the item Screen Share (or "Screen Casting"). Activate it, and a message will appear on the screen indicating that the TV is ready to connect, along with the device's name, which will appear in the list of available networks on your smartphone.
Pay attention to your privacy settings. Your TV may ask for confirmation the first time you connect a new device. This is to prevent unauthorized access and prevent neighbors from streaming content to your screen. A code or "Allow connection?" prompt may appear on the TV screen, which you must confirm with the remote.
☑️ Check TV readiness
If you're using older TVs (such as those with the NetCast system), the procedure may differ. You may need to manually enter a PIN or explicitly use Wi-Fi Direct through the network menu. Owners of these models are advised to check the user manual for a list of supported devices, as older protocols may not be supported by newer versions of Android.
Connecting an Android smartphone via Screen Share
Android devices offer several connection methods, as skin makers (Samsung, Xiaomi, Huawei) often rename standard features. The basic protocol used by LG is called Miracast. On Samsung smartphones, this feature is called Smart View, on Xiaomi smartphones it's called "Casting" or "Wireless Display," and on others, it's called "Screen Projection."
To get started, open the Quick Settings panel on your smartphone by swiping down from the top. Find the "Cast," "Smart View," or "Connect to a wireless display" icon. Tap it, and your phone will scan for available devices within Wi-Fi range. Your LG TV should appear in the list.
After selecting a TV from the list, a confirmation request will appear on your smartphone screen, and a notification about an incoming connection will appear on the TV. Use your TV remote to press "Accept" or "Confirm." The image from your phone's screen will then be copied completely to the TV.
- 🔍 Open the menu "Settings" → "Connected devices" → "Connect to PC".
- 📲 Click "Add device" and wait for the LG TV name to appear.
- 🔗 Select your TV and follow the on-screen instructions.
- ✅ Confirm the connection on both devices.
It is important to note that when using the function Miracast The connection is established directly via Wi-Fi Direct, even if both devices are connected to the router. This ensures minimal latency, which is important for gaming or presentations. However, image quality may be affected by interference in the air.
⚠️ Attention: When screencasting is active, audio from your phone is also transmitted to the TV. If you want to hear audio only through your phone, check the audio settings in the screencasting menu or turn down the TV volume.
Some apps, such as Netflix or YouTube, may block full-screen casting due to HDCP content protection. In these cases, the image may appear black, although the audio will still play. To watch videos from these services, it's better to use the built-in "Cast" feature within the app itself rather than mirroring the entire screen.
Stream from iPhone and iPad (AirPlay 2)
Apple device owners are at an advantage thanks to AirPlay technology. Modern LG TVs (2019 models and newer) have built-in AirPlay 2 support, allowing you to connect without installing additional apps. This ensures high picture quality and a stable connection.
To connect, make sure your iPhone and TV are connected to the same Wi-Fi network. Open Control Center on your smartphone (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 that appears. If this is your first connection, a four-digit code may appear on the TV screen. Enter this code on your iPhone to confirm pairing. Your smartphone's screen will then appear on the TV.
| Parameter | AirPlay 2 (Native) | Third-party applications | Lightning cable |
|---|---|---|---|
| Video quality | High (up to 4K HDR) | Average (depending on software) | Maximum |
| Delay | Minimum | High | Absent |
| Sound | Volumetric (5.1) | Stereo | Digital |
| Convenience | Built into iOS | Requires installation | Requires an adapter |
If your LG TV model does not support AirPlay 2 natively (e.g. models before 2018), you will need to install an app from LG, such as LG TV Plus, or use third-party solutions such as Replica or ApowerMirror, which can be installed on both TVs (via the LG Content Store) and iPhones.
What should I do if AirPlay can't find my TV?
Make sure AirPlay is enabled on your TV in the network settings. Sometimes a router reboot is required, as the Bonjour protocol (used for discovery) is sensitive to multicast settings. Also, check if your antivirus software is blocking local ports on your router.
The advantage of AirPlay is that you can use your phone while watching. You can minimize a video, reply to a message, or check email, and the streaming to your TV will continue uninterrupted. It also supports photo frame mode, where the TV displays your iCloud photos while you're not using your phone.
Using the LG ThinQ app to control
Official app LG ThinQ (formerly LG TV Plus) is a universal tool for interacting with your smart TV. It not only allows you to stream media files but also use your smartphone as a remote control, which is especially convenient for entering text using the phone's keypad.
To get started, download the app from Google Play or the App Store. Launch it and sign in to your LG account (or register). Click the "Add Device" button, and the app will scan the network. Select your TV from the list and enter the PIN displayed on the TV screen.
Once paired, you'll have access to the "Media" or "Gallery" functions. Select a photo or video saved on your phone and press the cast button. Unlike screen mirroring, the TV plays the file automatically using its decoders, which often provides better quality and smoothness.
- 📥 Download the LG ThinQ app from the official store.
- 📝 Register or sign in to your LG account.
- 🔗 Add a TV by scanning the QR code or selecting from the list.
- 🎬 Use the "Media" menu to select files on your phone.
The app also allows you to transfer files on the fly. You can open your gallery, select multiple photos, and send them to your TV with a single tap. This is ideal for sharing photos with friends or family during gatherings.
⚠️ Attention: The LG ThinQ app's functionality may vary depending on the TV model and webOS version. Some older models may only support basic remote control functions without media streaming.
Stream video from browsers and apps (Chromecast built-in)
Many LG TVs are equipped with Chromecast built-in (Google Cast) technology. This allows you to stream content from your phone's apps to your TV without overloading your smartphone's processor. The TV automatically downloads the video stream from the internet, saving battery life and your phone's data.
Open an app that supports casting (YouTube, Netflix, Google Photos, or the Chrome browser). Find the "Cast" icon (the rectangle with Wi-Fi waves in the corner). Tap it and select your LG TV. The content will play on the big screen, and you can use your phone as a remote.
In the Google Chrome browser on Android or iOS, you can open any webpage with video, tap the three dots in the menu, and select "Cast." You can choose to cast a tab or the entire screen. This is a universal method for websites that don't have a dedicated app.
It's important to distinguish between screen mirroring (Miracast/AirPlay) and content sharing (Cast). With screen mirroring, the phone displays what it sees on the screen. With content sharing, the phone acts only as a remote control, and the video is transmitted directly from the server to the TV. The second method is preferable for watching online movies.
Solution and troubleshooting
Even with proper setup, connection issues may still occur. Often, the cause is a simple missync of network settings. If your TV stops detecting your phone or the connection keeps dropping, try a full reboot: unplug the router for 30 seconds, then plug it back in, wait for it to load, and then reboot your TV and smartphone.
Another common issue is outdated software. Manufacturers are constantly improving communication protocols and fixing security bugs. Check for webOS updates in the menu. Settings → Support → Software Update.
Update menu: All Settings → General → About This TV → Check for UpdatesIf the problem persists, try forgetting the Wi-Fi network on both devices and reconnecting using the password. It's also worth checking whether the router has a limit on the number of connected clients or MAC address filtering that could be blocking one of the devices.
- 🔄 Restart your router, TV, and smartphone.
- 📡 Make sure both devices are on the same network (2.4 or 5 GHz).
- 🆙 Update your TV firmware through the support menu.
- 🔒 Disable the VPN on your smartphone if it is active.
In rare cases, antivirus software on your router or smartphone can block the local connection. Try temporarily disabling the protection to see if it's causing the problem. If this resolves the issue, add the devices to the exceptions list.
Why doesn't the TV see the phone in the list of devices?
Most often, the devices are on different subnets (for example, one is connected to a guest Wi-Fi network and the other to the main network). The issue could also be with the TV's Wi-Fi module drivers—try resetting the network settings in the TV menu.
How to reduce latency when gaming over Wi-Fi?
Minimal latency is critical for gaming. Use the 5 GHz frequency, turn off other bandwidth-consuming devices, and ensure there are no thick walls between the router and TV. Ideally, connect the TV with a LAN cable and keep your phone connected via Wi-Fi.
Is it possible to connect a phone to a TV without the Internet?
Yes, if you use Wi-Fi Direct or Miracast technology. In this case, the devices create a direct connection with each other, and no internet connection is required. However, streaming from online services still requires internet access.
Why does the video jerk when broadcasting?
This is a sign of insufficient channel bandwidth or severe interference. Try lowering the video quality in the app settings or moving the router closer to the TV. Switching to the 5 GHz frequency may also help.
