LG Smart TV LH570V: How to connect to your phone via Wi-Fi

Owners of TVs of the series LH570V Often faced with the need to display multimedia content from a smartphone on a large screen. This model, despite its age, remains popular due to its high-quality display and support for basic Smart TV functions. However, standard synchronization methods that work on new devices may require a specific approach. Understanding How to connect an LG Smart TV LH570V to a phone via Wi-Fi, provides access to viewing photos, videos, and even mirroring the Android or iOS interface.

The main difficulty is that this series of TVs uses earlier versions of the webOS platform, which isn't always compatible with modern data transfer protocols out of the box. You'll need to not only enable Wi-Fi but also properly configure network and app settings. In this article, we'll cover all available connection methods in detail, from built-in tools to third-party utilities that ensure stable operation.

Before moving on to specific steps, it's important to note the importance of a unified network environment. Devices must be on the same subnet for discovery protocols to function correctly. LH570V series TVs do not natively support AirPlay 2 protocol., so iPhone owners will have to use third-party solutions or the DLNA standard for media files. Below, we'll provide a step-by-step guide for various use cases.

Preparing equipment and network

The first step is to ensure a stable connection between the router and both devices. For the model LH570V It's critical that your TV and smartphone are connected to the same access point. If your router broadcasts two networks (2.4 GHz and 5 GHz), make sure both devices are in the same frequency range, preferably 2.4 GHz, as older TV Wi-Fi modules may not correctly detect devices in the 5 GHz range under certain security settings.

Check your TV's date and time settings. This is a minor issue, but clock synchronization is often the reason apps can't find your device on the network. Go to the settings menu and enable automatic synchronization via the internet. Also, make sure "AP Isolation" is disabled on your router; this prevents devices on your local network from communicating with each other.

  • 📡 Make sure your router is distributing IP addresses via DHCP; static addresses can cause a conflict.
  • 📱 On your smartphone, allow access to the local network for all used applications.
  • 📺 Update your TV firmware to the latest available version via the support menu.

To check the connection, you can use the TV's built-in browser or the network test in the settings. If the TV's internet connection works, the physical connection to the router is established correctly. Now you can move on to the software setup.

Using Screen Share (Miracast)

The most common way to broadcast an image is Miracast technology, which is called Miracast in LG TVs Screen ShareIt allows you to mirror your smartphone's screen to your TV without the need for additional wires. For Android device owners, this method is the most preferred, as it's built into the system and doesn't require installing additional software on the phone.

To activate standby mode on your TV, you need to find the appropriate app in the program list. The remote control often has a dedicated button labeled Screen Share Or you can access it through the app launcher. Once launched, a connection waiting screen will appear. On your smartphone, this feature may be called "Cast," "Smart View," "Wireless Monitor," or "Projection."

⚠️ Attention: When connecting via Screen Share, the image on your TV may experience a delay. This is normal for Miracast technology and does not indicate a hardware malfunction.

The device search process may take 5 to 30 seconds. If your phone doesn't detect the TV, try restarting the Screen Share app on the TV. Sometimes, turning the TV off and on again with the power button, rather than simply entering standby mode, helps.

Streaming via the LG TV Plus app

Official app LG TV Plus (or its newer version, LG ThinQ) offers advanced control functionality. It allows you to not only stream photos and videos from your gallery, but also use your smartphone as a remote control and mirror your screen. This solution is ideal if standard Miracast is unstable or requires more detailed configuration.

Once you install the app on your smartphone and launch it, it will automatically search for available TVs on the network. Select your model. LH570V from the list. A pairing confirmation prompt may appear on the TV screen; accept it using the remote. For full functionality, make sure the "Mobile TV" or "DLNA" function is enabled in the TV's network settings.

The app has a "Screen Share" or "Broadcast" section that activates mirroring mode. The advantage of this method is that the app is often better optimized for specific models than Android system services. It also allows you to conveniently control your media library playback, pausing or rewinding videos directly from your phone.

  • 📲 Download the app only from the official Google Play or App Store.
  • 🔐 When pairing, you may be asked to enter a code displayed on the TV screen.
  • 🎞️ Video streaming in resolutions up to Full HD (1080p) is supported.
What should I do if the app doesn't detect the TV?

If the automatic search doesn't yield results, try adding the device manually by IP address. To do this, find the TV's IP address in the network settings (under "Wi-Fi Status") and enter it in the app in manual addition mode. Also, check that your phone's antivirus software isn't blocking local connections.

Setting up DLNA to view media files

If your goal is not screen mirroring, but simply viewing photos or running video files stored on your smartphone, it is best to use the protocol DLNALG LH570V series TVs have a built-in media player that handles content playback from network-attached storage devices (NAS) perfectly. In this case, the phone acts as the server and the TV as the client.

To implement this scenario, you need to install a DLNA server app on your smartphone, such as BubbleUPnP or similar. After launching the app and selecting files to play, select your TV from the list of available rendering devices. The image or video will open in the TV's native player, ensuring better decoding quality and eliminating the lag typical of Screen Share.

This method is especially useful when viewing large, high-bitrate video files, which can lag when streaming live. The TV decodes the stream automatically, placing minimal strain on the smartphone's processor. However, it's important to remember that streaming the phone's interface via DLNA is not possible—only the content.

Troubleshooting connection issues

Despite the apparent simplicity, users often encounter a situation where devices "don't see" each other. One common cause is using a guest Wi-Fi network. If your phone is connected to the guest SSID and your TV to the main SSID, they will be isolated from each other at the router level. Switch both devices to the main network.

Problems can also be caused by a full DNS cache or IP address conflicts. Try rebooting your router by completely unplugging it for 10-15 seconds. This will clear the ARP table and assign fresh addresses to devices. On an LG TV, you can try resetting the network settings through the menu. Settings → Network → Wi-Fi connection → Advanced → Reset.

⚠️ Attention: Antivirus programs and firewalls on smartphones can block incoming connections from the TV. When you first try to connect, check your phone's security notifications.

If all else fails, check if your router has a limit on the number of connected devices. Some home networks may reach this limit, and the TV simply can't establish a connection with a new client (phone) to exchange data.

Alternative methods and third-party applications

In cases where the standard tools don't work satisfactorily, you can resort to third-party software. Popular applications like Cast to TV or Web Video Caster They can send a video stream directly to the TV's browser or through a built-in receiver. This bypasses system limitations and is often faster.

For iOS users who critically lack AirPlay, there are paid emulator apps that can be installed directly on the TV (if the webOS version supports it and it's available in the LG Content Store). These add the missing protocol, making the TV visible to the iPhone's standard Screen Mirroring feature.

Another option is to use Wi-Fi-enabled HDMI adapters (such as Chromecast or similar devices) that connect to the TV's HDMI port. In this case, the LH570V TV simply functions as a monitor, while an external dongle handles all the phone connection. This is the most reliable, but somewhat more expensive, method.

  • 🌐 Web Video Caster: Great for online videos from browsers.
  • 🍏 AirPin(PRO): AirPlay emulator for Android TV and webOS.
  • 🔌 HDMI dongles: transform any TV into a Smart Center with support for new protocols.
Why doesn't the LH570V TV detect my new iPhone?

The LH570V model is an older generation Smart TV and does not have built-in support for the AirPlay 2 protocol, which is used in modern iPhones for Screen Mirroring. The TV can natively only see Android devices via Miracast. To connect an iPhone, you need to use third-party apps from the LG Content Store (search for "AirPlay") or cast photos and videos through the LG TV Plus app, but not the full screen.

Is it possible to connect the phone via USB cable?

Yes, the LH570V model supports connecting mobile devices via USB, but its functionality will be limited. Your phone will be detected as external storage (like a flash drive). You can view photos, videos, and listen to music through the TV's media player, but you won't be able to mirror your screen or control your TV in this mode. A Wi-Fi connection is required for these functions.

How to improve picture quality during broadcasting?

Quality directly depends on the Wi-Fi speed and distance from the router. Try to place the router within direct line of sight of the TV. If your router is dual-band, make sure both the TV and phone are connected to the 5 GHz network (if the TV module supports it); this will provide the highest data flow. Also, close unnecessary apps on your phone to free up CPU resources for encoding the video stream.
