A stable connection and proper data transfer settings remain key. Users often wonder how to stream content from a phone or computer without unnecessary wires, using only the capabilities of their home network.
In this article, we will look at all the current methods for transmitting a video stream to LG screens running on the platform webOSYou'll learn how to set up a wireless network, which apps to use for streaming, and how to avoid common connection errors.
We'll explore both the system's built-in features and third-party streaming solutions. Properly organizing your local network will allow you to enjoy movies in high definition. without delays and breaks.
Preparing your home network and TV
The first and most important step is ensuring a high-quality connection. LG TVs, especially those with 4K HDR support, require high bandwidth. For playing large files, it's best to use a dual-band router operating in the same frequency range. 5 GHz.
Make sure your router supports the standards Wi-Fi 5 (802.11ac) or newer. Older devices may not be able to handle high-quality streaming, resulting in constant image buffering.
To check your current connection, go to the settings menu. Typically, the path looks like this: Settings → Network → Connect to a Wi-Fi networkHere you will see a list of available networks and signal strength.
If the signal strength is weaker than two bars, the streaming quality may be unstable. In this case, it might be worth moving the router closer to the TV or using a Wi-Fi repeater to boost the signal in the viewing area.
Broadcasting from mobile devices (Screen Share)
The fastest way to display an image from a smartphone on a big screen is to use technology Miracast, which is often called Screen Share on LG TVs. This feature is built into the system and doesn't require any additional software to be installed on the TV.
To get started, make sure your smartphone and TV are connected to the same wireless network. Press the button on the remote control. Input or select an application Screen Share in the launcher's main menu.
- 📱 On Android smartphones, the feature may be called "Cast," "Smart View," or "Wireless Monitor" in the notification shade.
- 🍏 For Apple devices, you need to use the AirPlay 2 function, which is supported by most modern LG models.
- 🖥️ On Windows 10 and 11, you can press a key combination
Win + Kto search for available displays.
The pairing process usually takes a few seconds. Once the connection is confirmed, an exact copy of the smartphone's image will appear on the TV screen. This is convenient for viewing photos, videos from the gallery, or even playing games.
⚠️ Attention: When using Screen Share, your smartphone's screen must be constantly on, which quickly drains battery life. For extended viewing, it's better to use built-in apps.

Using DLNA and media servers
If you store your movie collection on your computer or network storage NASDLNA technology is the ideal solution. It allows you to stream media files directly to your TV using its built-in player, providing better picture quality than with a screen.
To use this method, media streaming must be enabled on your computer. In Windows, this can be configured through "Media Streaming Settings" in Control Panel.
On your LG TV, you need to open the app Photos and videos* (or "Media Player" on older models). The system will automatically detect available servers on the local network.
| Parameter | Description | Recommendation |
|---|---|---|
| Protocol | DLNA / UPnP | Standard for local area networks |
| Video formats | MP4, MKV, AVI | Depends on TV codecs |
| Stability | High | Doesn't depend on the phone screen |
| Control | From the TV remote control | Easy to navigate |
It's important to understand that your TV must support the codec the movie is encoded in. If you see a format error message when launching the movie, you'll need to use a third-party player or convert the file.
Why can't the TV see the computer?
Often the problem lies with the network type. In Windows, make sure the network is marked as "Private" and not "Public." On a public network, device discovery is disabled by default for security reasons.
Aggregator apps and online cinemas
The most popular way to consume content today is by installing native apps from the store. LG Content StoreThey already have optimal buffering and high resolution support configured.
To install, go to the app store on the main panel. Find the desired app (for example, YouTube, Netflix, Kinopoisk, Ivi) and click the "Install" button.
Some services may require a paid subscription or an account. It's more convenient to log in through the website on a computer or smartphone by scanning the QR code that appears on the TV screen.
- 🎬 Online cinemas: They offer 4K and HDR content adapted to your LG's display.
- 🌐 Browser: The built-in web browser allows you to open websites directly, but using the remote control can be inconvenient.
- 📡 IPTV: To watch TV channels, you can install applications like Peers.TV or OTT Club.
⚠️ Attention: App interfaces and available content may vary depending on region and developer updates. If the app isn't available in your region, check the country settings in your LG profile.
Solving buffering and quality issues
Even with ideal settings, playback issues may still occur. These are most often due to bandwidth congestion or insufficient processing power on the TV when decoding large files.
If the image freezes but the sound continues (or vice versa), try lowering the stream quality in the app settings. It's also worth checking if someone else is actively downloading content.
In some cases, clearing the app cache can help. To do this, go to Settings → All settings → General → Storage and select clear data for the problematic app.
Recommended internet speed for 4K: 25 Mbps
Recommended speed for Full HD: 5-10 Mbps
If problems persist, try rebooting your router and TV. Completely disconnecting from the power supply for 10-15 seconds can help clear temporary network module errors.
What to do if Wi-Fi reception is poor?
If moving the router is not possible, consider purchasing a Wi-Fi adapter with an external antenna (for USB models) or using Powerline adapters that transmit internet through electrical wiring.
Frequently Asked Questions (FAQ)
Is it possible to connect a phone via HDMI cable instead of Wi-Fi?
Yes, this is possible. For Android, you'll need USB-C to HDMI adapters that support MHL or DisplayPort Alt Mode. For iPhone, you'll need a Lightning to HDMI adapter. The TV will switch to external source mode.
Why doesn't my LG TV see my laptop?
Make sure both devices are on the same subnet (same router IP address). Check your computer's firewall settings—it may be blocking incoming connections from the media server.
Does my TV support MKV format?
Most modern LG Smart TV models support the MKV container. However, if the container uses a rare audio codec (such as DTS in older models), sound may not be heard. In this case, external speakers or the VLC app will help.
How to increase the volume when watching on a phone?
Volume is controlled separately on your phone and TV. Make sure the volume is turned up to maximum on your mobile device, then increase it using the TV's remote.
