In this article, we'll cover both direct wireless protocols and physical connections that guarantee operation even if the external network is completely disrupted.

Particular attention should be paid to the compatibility of ports and operating system versions, as this will determine the choice of the optimal cable or adapter. LG Smart TV They offer a wide range of tools for interacting with peripherals, but activating them requires understanding the specifics of each interface. Let's look at the main solutions step by step.

Using Wi-Fi Direct technology for direct transmission

The most convenient wireless method that does not require a router is the technology Wi-Fi DirectIt allows you to create a direct connection between your smartphone and TV, bypassing the access point. Unlike traditional Wi-Fi, where all devices are connected to a single router, the TV itself acts as a receiving node or creates its own micro-network.

To get started, you need to activate the appropriate function in the TV menu. Typically, the path looks like this: Settings → Network → Wi-Fi DirectOnce turned on, the TV will begin searching for available devices or will appear in the list of available networks on your phone. It's important to note that using this method may cause your phone's internet connection to stop working, as the Wi-Fi module will switch to a direct connection with the TV.

⚠️ Please note: When actively using Wi-Fi Direct to transfer large, high-resolution video files, you may experience delays or reduced image quality due to bandwidth limitations without a router.

On your smartphone, the process is just as simple: open your gallery, select the desired photo or video, tap the "Share" or "Cast" button, and select your TV from the list. If the devices haven't been paired before, a connection confirmation prompt may appear on the TV screen, which you'll need to accept with the remote. This method is ideal for quickly sharing content without the hassle of wires.

Wired connection via HDMI and adapters

If you want the highest image quality without compression or lag, nothing beats a wired connection via an interface. HDMIThis is the most reliable option, working completely regardless of any wireless networks or TV software settings. However, modern smartphones rarely have a full-size HDMI port, so special adapters are required.

For owners of Android devices with a port USB Type-C cables or adapters that support the technology are required MHL (Mobile High-Definition Link) or SlimportNot all USB-C cables support video transmission, so pay attention to the specifications when purchasing. Connect the adapter to your phone, plug the HDMI cable into it, and connect the other end of the cable to an available port on your LG TV.

For device users Apple iPhone an adapter will be required Lightning to HDMI (or USB-C to HDMI (for new models). After the physical connection, you need to switch the signal source on the TV. Use the remote control, press the button Input or Settings and select the appropriate port, for example, HDMI 1The image from your phone's screen will instantly appear on your TV in full resolution.

Broadcast via Miracast and Screen Share

Technology Miracast, known on LG TVs as Screen ShareMiracast allows you to mirror your smartphone's screen to your TV over the air without a router. Unlike Wi-Fi Direct, which is often used simply for file transfers, Miracast creates a real-time video stream, making it ideal for gaming or watching videos from apps that don't support standard DLNA.

To start the process, find the button labeled "On the LG TV remote control" Screen Share Or go to the apps menu and launch the app with the same name. A message will appear on the screen indicating that you're waiting for a connection. On an Android smartphone, this feature may be called "Cast," "Smart View," "Wireless Projector," or "Cast," depending on the model and OS version.

⚠️ Please note: The Screen Share feature on some LG models may require an initial handshake connection, which is theoretically possible without the Internet, but some applications may require a one-time network connection for initial setup.

Once the TV is detected, tap its name in the list on your phone. Your smartphone's screen will be mirrored to the larger display. It's important to understand that when using Miracast, the phone and TV create their own P2P (Point-to-Point) network, so external internet access will not work on your phone at this point unless you're using simultaneous data transfer.

Why might Miracast not work?

This feature may be unavailable if the TV is running a heavy app that consumes processor resources, or if the TV firmware version is outdated. Also, some content-protected apps (Netflix, Disney+) may block Miracast streaming due to HDCP protection, requiring the use of built-in Smart TV apps.

Playing files via USB storage device

The oldest, but at the same time one of the most reliable methods is the use of ordinary USB flash driveThis method completely eliminates any issues with protocol compatibility, drivers, or wireless interference. You'll need a microSD card with an adapter or a USB flash drive, as well as a smartphone that supports the technology. OTG (On-The-Go).

First, connect the flash drive to your smartphone via an OTG cable. Copy the desired photos or videos to the drive's root folder or create a convenient folder structure. Once copying is complete, safely remove the drive from your phone and insert it into the USB port on the panel or back of your LG TV.

The TV will automatically detect the new device. A pop-up window will appear on the screen asking you to open the content, or you will need to press the button. Input and choose USB in the list of sources. Built-in media player LG supports most popular image (JPEG, PNG) and video (MP4, MKV, AVI) formats.

Connection specifics for Android and iOS

The approach to image transfer varies significantly depending on your mobile device's operating system. In the ecosystem Android Users have more freedom in choosing methods, including direct recording to USB and using open standards like Miracast. At the same time, devices iOS (iPhone, iPad) require the use of Apple proprietary protocols such as AirPlay, or specialized applications.

For iPhone owners, an important consideration is whether your TV supports the AirPlay 2 protocol. If your LG TV is new enough (2019 models and newer), it supports AirPlay natively. However, to use AirPlay without a Wi-Fi router, both devices must be on the same network. In Wi-Fi-less environments, this is only possible via Wi-Fi Direct (if the TV emulates an access point) or via a wired adapter.

On Android devices, a function is often found Smart View (Samsung) or similar devices that can operate in Wi-Fi Direct mode. For Android, it's also possible to use proxy apps that can be installed both on the TV (via USB, if the APK installation option is available) and on the phone, creating a local network. However, the most stable method for a pure connection without a network remains HDMI or a USB flash drive.

⚠️ Note: Menu interfaces and function names may vary depending on the webOS version on your LG TV. If you don't see the described options, check the official user manual for your specific model for the exact function name.

Troubleshooting and diagnostics

Even simple methods can cause technical difficulties. If the TV doesn't detect the phone or the image is transmitted erratically, first check the physical integrity of the cables and adapters. Often, the problem lies with cheap adapters that don't support video transmission and are designed only for charging.

If you're experiencing wireless connection issues (Wi-Fi Direct, Miracast), try restarting both devices. Network module failures are common after extended use. Also, make sure any screen saving features on your TV are disabled, as they could interrupt the connection when idle.

If you see a picture but no sound, check the audio settings in your TV menu. Sound may still be output to your phone's speaker. HDMI or Screen Share settings often have an option to select the audio output device, which should be set to "TV" or "External Speakers."
