When your home Wi-Fi router suddenly stops working or you're in a location where wireless coverage is unavailable, it often becomes difficult to view photos or videos on a big screen. However, a lack of internet access doesn't mean you can't stream content from your smartphone to your TV. LGModern technologies make it possible to establish a direct connection using only the hardware capabilities of the devices.
There are several proven methods for establishing a connection between your gadget and TV, each with its own advantages depending on your needs. You can use a physical cable connection or use wireless technologies that operate locally without access to the global network. In this article, we'll cover all the current methods in detail so you can choose the most suitable option for your model.
Before you begin setup, make sure both devices are charged or connected to a power source, as streaming video can significantly drain battery power. It's also important to consider that operating system version on your smartphone may affect the availability of some features, especially if you have older Android or iOS models.
Using an HDMI cable for live streaming
The most reliable and high-quality way to transfer images remains a physical connection via an interface HDMIThis method guarantees a stable, high-resolution image without lag, which is critical for watching fast-paced movies or playing games. To enable this connection, your smartphone must support video output technology, often referred to as MHL or SlimPort.
You'll need a special adapter with a connector compatible with your phone (USB Type-C or Micro-USB) on one end and a standard HDMI port on the other. After connecting the cable to your phone and TV, you'll need to switch the signal source to TV using the remote. To do this, press the button. Input or Source and select the appropriate port, for example, HDMI 1.
⚠️ Note: Not all smartphones support video transfer via USB. If the image doesn't appear after connecting the adapter, check your device's specifications on the manufacturer's website or in the manual.

If this doesn't happen, make sure the adapter is working properly, as cheap alternatives often lack the necessary internal chip for signal conversion. Image quality in this case will depend on your phone's capabilities and supported resolution.
☑️ Checking HDMI connection readiness
Using a cable ensures minimal image lag, making this method ideal for gaming. However, it's important to remember that the phone may become very hot in this mode, as the processor is under heavy load converting the video stream. It's recommended to monitor the device's temperature during long gaming sessions.
Connecting via USB cable and storage mode
If you just want to view photos or videos stored on your phone, you can use a regular USB cable. In this case, the TV LG The smartphone will be treated as an external storage device, similar to a flash card or hard drive. This is the simplest method, requiring no complex network settings.
To begin, connect your phone to the TV's USB port using a standard data cable. A prompt will appear on your smartphone's screen asking you to select the USB connection mode. Select File transfer or MTP (Media Transfer Protocol). Without this step, the TV will not be able to see the contents of the memory.
| Connection type | Image quality | The need for the Internet | Difficulty of setup |
|---|---|---|---|
| HDMI cable | Maximum (up to 4K) | Not required | Low |
| USB (MTP) | Depends on the file | Not required | Low |
| Miracast Direct | High (depending on interference) | Not required | Average |
| DLNA (Local) | High | Not required (Local Area Network) | High |
Once you've selected the mode, take your TV remote and go to the signal source menu. This is usually a button with a square with an arrow inside it, or a separate key. My Files / Media Player In the Smart TV menu, find your phone in the list of connected devices; its name may appear as the device model or as "USB Device."
The main advantage of this method is the ability to play files of any format supported by the built-in media player. LGYou can scroll through photos, pause videos, and rewind them. However, you can't stream online or broadcast your game screen in real time via USB—only file access.
Miracast and Screen Share technology without a router
Technology Miracast Allows you to stream your smartphone's screen to your TV via a direct Wi-Fi connection, bypassing the router. In TVs LG This function is often called Screen Share or Smart ViewThe device creates its own wireless network, to which the phone connects, providing video stream transmission.
To activate this feature, open the TV settings menu and find the section for mobile device connections. On newer webOS models, this may be an app. Device Connector or a separate line in the input list. After launching, the TV's name will appear on the screen, indicating it's waiting to connect.
On your smartphone, you need to open the quick settings panel and find the function Broadcast, Smart View or Wireless monitorThe list of available devices should update, and you will see the name of your TV. LGClick on it to start pairing.
⚠️ Please note: When using Miracast, your phone's battery drains significantly faster than usual. It is recommended to keep your device connected to a charger while watching.
This method is convenient because it doesn't require any wires, allowing freedom of movement within the room. However, image quality and smoothness may be affected by the presence of other wireless networks nearby that create interference in the 2.4 GHz frequency. If the picture is choppy, try moving your phone closer to the TV.
Organizing a local DLNA network
Protocol DLNA Allows you to share multimedia content between devices on the same network. Even without internet access, if your router is turned on (or if your phone can act as a TV hotspot, although this is rare for DLNA), devices can see each other. "No Wi-Fi" here means there's no global internet connection, but a local connection.
If you have a router but no internet, connect both your TV and phone to it via Wi-Fi. This will put them on the same local network. Open your phone's gallery or video player, select a file, and press the cast button (usually a screen icon with arrows). Your TV should appear in the list of devices. LG.
An alternative option is to use dedicated controller applications such as TV Cast Or the built-in "Media Streaming" feature. It scans the local network and finds available renderers (TVs). This method is ideal for watching high-quality, uncompressed videos from your phone's memory.
Why might DLNA not work without the Internet?
Some apps require initial internet authorization to launch for the first time. If this is the case, try opening the app with the internet enabled first, then disconnecting from the internet.
It's important to note that when using DLNA, you don't cast your phone's entire screen; you only send a specific media file for playback. This frees up your smartphone for other tasks. You can minimize your gallery and chat on Messenger while watching a movie on TV.
Wi-Fi Direct connection
Technology Wi-Fi Direct It's the foundation for many smart TV features and allows for a direct connection between two devices without an access point. Unlike Miracast, which primarily streams images, Wi-Fi Direct creates a channel for transmitting any type of data.
On TV LG This feature is often built into the connection menu of mobile devices. Activate Wi-Fi Direct in the TV's network settings. On your phone, find the "Wi-Fi" section in the Wi-Fi settings. Wi-Fi Direct and start the search. When your TV's name appears, select it to pair.

⚠️ Note: Menu interfaces may vary depending on your webOS firmware version. If you don't see Wi-Fi Direct, check the "General" or "Network" section in your TV settings.
The main advantage of this method is its versatility. Wi-Fi Direct can be used not only to view photos but also to transfer documents or other files, provided the TV has a built-in file manager that supports such operations. Data transfer speeds are quite high.
Solving common connection problems
Even if you follow all the instructions, technical difficulties may arise. Often, the problem lies in incompatible file formats or outdated software. If the TV LG If your phone isn't detected, first check if the discovery feature is enabled on both devices.
In some cases, simply restarting the communication modules helps. Try turning Wi-Fi off and on again on your phone, and also rebooting your TV by completely disconnecting it for 10 seconds. This clears temporary network stack errors.
If you're using a cable connection, make sure the ports are intact. Dust in the USB port or oxidation on the HDMI contacts can interfere with signal transmission. Gently cleaning the ports with compressed air often solves the problem of an "invisible" device.
What should I do if the video is lagging when connected wirelessly?
Try lowering the streaming video resolution in the app settings or moving your phone closer to the TV receiver. Disabling Bluetooth on your phone to free up airtime may also help.
Comparison of methods and selection of the optimal option
The choice of connection method depends on your specific needs. A USB cable is sufficient for viewing family photo archives. For presenting presentations or working with documents, HDMI, which provides crisp text, is better. Wireless methods are convenient for quick access to content without the clutter of cables.
The age of the equipment should also be taken into account. Older models LG may not support modern codecs or Miracast protocols. In such cases, an external adapter connected to HDMI becomes the only output, turning any TV into a smart TV.
In conclusion, the lack of a Wi-Fi network isn't a critical limitation. A combination of wired and direct wireless technologies provides complete control over multimedia content. Experiment with different methods to find the most convenient for your hardware configuration.
Is it possible to connect an iPhone to an LG without Wi-Fi?
