A local network created by the TV or phone itself allows you to stream high-definition video, run presentations, or display photos. The key is to choose the right one. data transfer protocol and follow the sequence of actions when pairing devices.

Using Screen Share (Miracast) technology without a router

The most common method, which does not require wires and an external router, is based on technology MiracastIn LG TVs this function is often called Screen ShareThe method involves the TV creating its own Wi-Fi Direct access point, which the smartphone connects to directly. This allows for image and sound transmission with minimal latency, making it ideal for viewing photos or videos from your gallery.

You don't need internet access to get started. Just go to the Smart TV menu and find the app. Screen Share or Connecting to a mobile deviceOn some models with the new operating system WebOS This may be hidden in the signal source selection menu. Input or in the section ConnectionsAfter launch, a connection waiting message will appear on the screen, and the TV will become visible for searching by external devices.

⚠️ Attention: Make sure your TV doesn't have Guest Network mode or Client Isolation enabled if you've previously set up your router, although when using pure Wi-Fi Direct these settings usually won't affect the direct connection.

The next steps depend on your smartphone. On Android devices, this feature may have different names: Broadcast, Smart View (Samsung), Screen projection or Wireless monitorThis technology isn't natively supported on iPhones, so iOS users will have to look for alternatives or use third-party apps, which we'll discuss below. Once the TV is found in the list of available devices, tap it to pair.

Connection via HDMI cable and adapters

If wireless methods are in doubt or require maximum signal stability (for example, for gaming), the best solution is wired connectionThis method guarantees the transmission of images in their original quality, without compression or delays. To implement this, you'll need a special adapter, as modern smartphones rarely have a full-size HDMI port.

Owners of Android smartphones with a USB Type-C port should check for support of the standard. MHL or Alt ModeIf there is support, it is enough to purchase an adapter. USB-C to HDMIFor iPhones from the 5 model up to the iPhone 14, you will need an adapter. Lightning to HDMI (Digital AV Adapter). The new iPhone 15 and 16 models use the USB-C port, but may also require checking the compatibility of video output adapters.

The connection process is extremely simple and does not require complex menu settings:

• 🔌 Connect the HDMI cable to your LG TV and remember the port number (e.g. HDMI 1).
• 📱 Insert the adapter into the charging port of your smartphone.
• 📺 Switch the signal source on your TV by pressing the button Input on the remote control and selecting the appropriate port.
• 📲 Your phone screen will instantly be displayed on your TV (mirroring mode).

It's important to understand that with this connection, the phone's battery may drain quickly due to the active video stream. Some original adapters have an additional port for connecting a charger, which allows compensate for energy consumption while watching. It's also worth noting that some content-protected apps (such as Netflix or Disney+) may block cabled image output due to HDCP protection policies, although this is less common than with wireless transmission.

Broadcasting via USB drive

The simplest and "old school" method that works on absolutely all LG TVs, even older models without Smart TV, is to use USB flash drivesWhile this isn't a live screencast, it's ideal for watching pre-downloaded movies, TV shows, or sharing photos and presentations.

You need to copy media files from your phone to a USB drive. This may require an adapter. OTG (On-The-Go), if your phone supports connecting external peripherals. After copying the files, remove the flash drive and connect it to the TV's USB port. WebOS will automatically prompt you to open a list of files or launch an application Photo / Video.

The advantage of this method is its independence from network software glitches and format compatibility. LG TVs are excellent omnivores and read most popular formats: .mkv, .mp4, .aviIf the built-in player does not open the file, you can install a third-party media player from the LG Content Store, for example, VLC or MX Player, which have extended codecs.

Using a mobile hotspot (Internet sharing)

Users often wonder if it's possible to use their phone's mobile internet to connect to a Smart TV. The answer is yes, it's possible through the [Internet connection] function. Access point (Hotspot). In this case, your smartphone acts as a router, distributing a Wi-Fi signal to which your LG TV connects.

This method requires a high-volume data plan, as the TV can consume a lot of data for app updates, email, or streaming. However, if your goal is simply to connect devices for control or use of network-dependent apps (even without actual internet access for local tasks), this method is suitable.

To set up, follow these steps:

1. Enable the "Wi-Fi hotspot" mode on your smartphone in the network settings.
2. Set the network name and password (it is advisable to use WPA2 security).
3. On your LG TV, go to Settings → Network → Connect to a Wi-Fi network.
4. Find your network name in the list and enter the password.

⚠️ Attention: When using a mobile hotspot for Smart TV, monitor your data usage. Background app updates or automatic downloads of high-quality content can quickly deplete your data plan.

Once connected, the TV will assume it's connected to the internet. This allows you to launch apps that require authorization or use Smart TV features that are blocked without a network connection. However, for simple screen sharing (Miracast), this method is unnecessary, as Wi-Fi Direct is faster and doesn't eat up your mobile data.

Why doesn't the TV see the phone in hotspot mode?

Sometimes the problem lies in the frequency range. If your phone only broadcasts Wi-Fi on the 5 GHz band, and your old LG TV only supports 2.4 GHz, they won't see each other. Try forcing the 2.4 GHz band into your phone's hotspot settings.

Connecting iPhone (iOS) to LG TV

Apple product owners are less fortunate with native free router-free methods, as the ecosystem iOS tailored to the protocol AirPlayLG TVs support AirPlay 2, but this feature often requires both devices to be on the same Wi-Fi network created by a router. Without a router, native streaming may not work.

However, there are workarounds. Some LG models allow for a direct connection for AirPlay, but this depends on the version. WebOSIf there is no automatic detection, you can try third-party apps from the App Store that emulate a connection. For example, apps like Replica or TV Cast can help, but they often require the devices to be on the same network (which is solved via a hotspot, described above).

For iPhones, the most reliable method remains the cable method (Lightning/USB-C to HDMI), described in the relevant section. It works reliably on all LG models, from older LEDs to newer OLEDs, and doesn't require network configuration. Just connect, and the picture is on the screen.

Troubleshooting and diagnostics

Even if you follow all the instructions, technical difficulties may arise. Often, the problem lies in outdated software. Check the version firmware your TV in the menu Settings → Support → Software UpdateIf your TV has ever been connected to a network, it may not have updated and the wireless display features may not work properly.

Another common issue is resolution incompatibility. If the phone attempts to display an image at a non-standard TV resolution, the screen may remain black, although audio will continue to play. Try changing the output resolution in the phone settings (if available in the engineering menu or developer options) or in the external display settings.

It's also worth mentioning the reboot. Trivial power reset (Unplugging the TV for 1-2 minutes) often clears the network module cache and resolves Wi-Fi Direct module freezes. Don't ignore this simple step before troubleshooting complex technical issues.

⚠️ Attention: LG TV interfaces are constantly being updated. The layout of menu items may vary depending on the model year and webOS version (3.0, 4.0, 5.0, 6.0, and later). If you can't find the desired function, use the search in settings (magnifying glass icon) or refer to the official documentation for your specific model.
