There are numerous wired and direct wireless solutions that operate locally, without access to the global network. In this article, we'll take a detailed look at all the current methods, from traditional cables to advanced digital interfaces.
The most obvious and stable option remains a physical connection. A cable ensures high-definition signal transmission without lag or compression artifacts, which is especially important for watching 4K video or gaming. However, the capabilities of the device itself shouldn't be discounted. TV, which can act as an independent signal receiver.
Using an HDMI cable for live streaming
The most universal method, suitable for almost any model of smartphone and TV LGThe most common connection is via HDMI. This interface transmits both video and audio simultaneously, ensuring the highest picture quality. If your phone doesn't have a built-in HDMI port, you'll need a special adapter, often called an adapter or dock.
For Android devices with a USB Type-C connector, it is important that the port supports the standard MHL (Mobile High-Definition Link) or Alt ModeWithout this support, the phone will only be able to charge via the cable, but will not transmit video. iPhone owners need an original Lightning to Digital AV Adapter or a USB-C to HDMI adapter for newer models, as cheaper third-party alternatives often perform poorly.
- 🔌 Connect the adapter to the charging port of your smartphone.
- 📺 Connect the adapter and TV with an HDMI cable.
- 📲 On the LG remote, press the Input button and select the appropriate port.
- 🎬 The image from your phone screen will automatically appear on your TV.
⚠️ Note: Some budget smartphone models may not support video output via USB, even if they have a Type-C connector. Check your device's specifications on the manufacturer's website before purchasing an adapter.
After physical connection, the TV LG Usually, the new signal source is detected automatically. If it doesn't, use the remote control to manually select the input. In the signal source menu, look for the designation that corresponds to the port number you plugged the cable into, for example, HDMI 1 or HDMI 2.
Screen Share (Miracast) technology without a router
Many users mistakenly believe that the function Screen Share or Miracast LG TVs require a Wi-Fi router. This technology actually works on the principle of Wi-Fi Direct. This means that the TV itself creates an access point to which the smartphone connects directly, bypassing the external network.
To activate this mode, you don't need to configure complex network settings. Simply enable the feature on your TV and start searching for devices on your phone. In Android, this feature may be called "Cast," "Smart View" (on Samsung), or "Wireless Monitor." On iPhone, the equivalent is AirPlay, but it requires both devices to be on the same network, which is more difficult to achieve without a router, so wired methods are best for iOS.
☑️ Check Screen Share Readiness
The connection process is as follows: on the LG TV, go to the Smart TV menu and launch the application Screen ShareThe device will go into standby mode. Next, on your smartphone, select the Cast function in the Quick Settings panel or in the Display settings menu. Your TV should appear in the list of available devices.
⚠️ Please note: When using Wi-Fi Direct, data transfer speeds may be lower than via a router, sometimes resulting in micro-delays in cursor or audio. This isn't a problem for viewing static photos, but lag may be noticeable in fast-paced games.
It's important to note that with this connection, your phone's Wi-Fi connection won't work, as the Wi-Fi module is busy transmitting images. If you need network access, use 4G/5G mobile data, but keep in mind that this will be deducted from your data plan.
Connect via USB cable and view media files
If your goal isn't to broadcast your screen in real time, but simply to show photos or videos stored on your phone's memory, then the easiest way is to use a regular USB cable. TVs LG with Smart TV function can recognize connected mobile devices as external storage devices.
To use this method, connect your smartphone to the TV's USB port. A request for data access may appear on the phone's screen. Select "File Transfer" or "MTP." The TV will then see your phone's internal memory or memory card as a regular flash drive.
| Parameter | Description | Recommendation |
|---|---|---|
| Cable type | USB Type-A to Type-C / Micro-USB | Use the original cable for stability |
| USB mode | MTP (Media Transfer Protocol) | Be sure to select in the phone notification |
| Video formats | MP4, MKV, AVI | Check your TV's codec support |
| Photo formats | JPEG, PNG, BMP | Supported by all LG models |
Once connected, go to the TV menu and select the signal source USBA file manager or gallery will open, where you can select the files you want to play. This method is ideal for viewing large video files that can lag during wireless transmission.
What should I do if the TV doesn't detect the phone via USB?
If your LG TV isn't responding to a connection, try switching your phone to "Charge Only" mode and then selecting "File Transfer" again. Also, make sure the cable is working properly and supports data transfer, not just charging. Some "charging" cables don't have internal data lines.
Connecting an iPhone to an LG without a network
It's harder for Apple device owners to get by without a router, as the ecosystem iOS It's designed to work via AirPlay, which requires a shared Wi-Fi network. However, there are workarounds. Some modern LG TVs support the AirPlay 2 protocol, which, in certain configurations, can work via Wi-Fi Direct, but this depends on the specific model and firmware version.
The most reliable method for connecting an iPhone remains using a Lightning to HDMI or USB-C to HDMI cable. This ensures all functions work, including high-definition audio and video output. Third-party adapters may require additional power, so it's recommended to connect the charger to the adapter simultaneously.
- 🍎 Use certified adapters (MFi) for stable operation.
- 🔋 Connect the charger to the adapter if the screen goes dark or flickers.
- 📺 Switch your TV to the appropriate HDMI input.
- 🔒 Allow access to the device if a trust request appears on your phone screen.
It's worth mentioning that with a wired connection, the iPhone continues to function, and you can use apps without displaying them on the screen if the app doesn't support external displays. However, many video players and gallery apps simply mirror the image.
Troubleshooting device detection issues
Sometimes the connection process doesn't go smoothly: the TV doesn't detect the phone, the picture flickers, or there's no sound. In these cases, it's necessary to run a basic diagnostic. First, check the integrity of the cables and adapters. Often, the problem lies in a damaged cable or a poor-quality adapter.
If you're using a wireless connection via Wi-Fi Direct, try resetting the Wi-Fi module on your phone: turn it off and then back on. Restarting the TV itself by completely unplugging it for 10-15 seconds also helps. This will clear any temporary errors in the network module.
If you're experiencing issues with screen resolution or a black image with audio, try changing the output settings on your phone. Go to display settings and select standard resolution. 1920×1080 or 1280×720. Too high a resolution or non-standard frame rate may not be supported by the TV in direct connection mode.
⚠️ Note: The LG TV menu interface (WebOS) may differ depending on the model year. The menu item names may vary, but the logic remains the same. Always consult the manual for your specific model if the default paths are different.

Can you play games on your phone via HDMI on your TV?
Yes, you can. When connected via HDMI, the phone functions like a computer, displaying images on a larger screen. However, for a comfortable gaming experience, you'll need a gamepad that can be connected to the phone via Bluetooth, or you'll need to use the phone's touchscreen as a controller, which isn't always convenient.
Is mobile internet traffic used up when connected via cable?
No, when connected via HDMI or USB, only data is transferred from the device to the screen. Mobile data is not consumed unless you're playing an online video or a network-required game. Internet access is also not required in USB storage mode.
