Modern mini-stations Compact gaming computers are becoming increasingly popular thanks to their portability and ability to turn any screen into a powerful multimedia center. However, the lack of an HDMI cable or the desire to eliminate unnecessary wires often leads users to consider wireless connectivity. TVs LG, equipped with an operating system webOS, offer a wide range of built-in tools for organizing such a connection, but the setup process requires an understanding of the specifics of data transfer protocols.
Unlike a wired connection, where the signal is transmitted directly, wireless streaming depends on many factors, from the bandwidth of your router to the software version on your TV. You need to keep in mind that for a comfortable gaming or video viewing experience, 4K A standard Wi-Fi router may not be suitable for this resolution, and 5 GHz support will be required. In this article, we'll cover all available synchronization methods in detail so you can choose the best option for your hardware configuration.
Preparation of equipment and network infrastructure
Before starting the setup, make sure that all devices are in a single information space. Mini-station, be it a laptop, gaming PC or smartphone, and a TV LG must be connected to the same Wi-Fi network. If your router supports dual-band mode, it's highly recommended to use the 5 GHz frequency, as it provides higher data transfer rates, which is critical for reducing input lag.
Please pay attention to your TV's firmware version. Older versions webOS may not support modern video coding standards or protocols Miracast Fully. Updating the system often resolves issues with the device's visibility in the list of available receivers.
☑️ Check before connection
⚠️ Note: If your router broadcasts two networks with the same name (SSID) for 2.4 GHz and 5 GHz, devices may automatically switch between them, which will break the connection. For stable operation, it's best to temporarily separate the network names or force both devices to connect to the 5 GHz band.
Using the built-in Screen Share (Miracast) feature
The most direct way to cast from your Windows PC or Android device to your TV LG - this is technology Miracast, which is called in the LG TV menu Screen ShareThis method doesn't require any additional software and works on the Wi-Fi Direct protocol level. To activate the feature, press the house or up arrow button on the remote control to open the main menu and find the app. Screen Share or Display.
On the side of the computer with the operating system Windows 10/11 You need to use the system projection function. Press the key combination Win + K, after which the "Connection" panel will appear on the right. Your TV should appear in the list of available devices. LGOnce selected, the pairing process will begin and the desktop or extended screen image will appear on the TV.
- 📺 Launch the app on your TV
Screen Shareand select the "Mirroring" or "Mobile Broadcast" mode. - 💻 On PC, click
Win + Kand wait until your TV's name appears in the list. - 🔒 When connecting for the first time, a permission request may appear on the TV screen - confirm it with the remote control.
- ⚙️ To improve quality, select "Second screen only" in the Windows projection settings to avoid overloading your graphics card with image rendering on your PC monitor.
It's worth noting that Miracast is sensitive to interference. If you experience artifacts or flickering, try moving the router further away from the TV or, conversely, ensuring a clear line of sight between the transmitter and receiver. Connection quality also depends on antenna module your mini-station.
Why might the Miracast connection drop?
The Miracast protocol creates a direct connection between devices, but it often uses the same frequency as your router's internet connection. This can cause conflicts, especially in apartment buildings where the airwaves are clogged with neighbors' signals. Switching your router to a free Wi-Fi channel may solve the problem.
Streaming via Apple AirPlay 2 for Apple devices
Equipment owners Apple, including MacBook, iPad, and iPhone, can take advantage of native protocol support. AirPlay 2, which is built into modern LG TVs. This method ensures stable transmission of high-quality video and audio. For this feature to work, make sure that the TV settings are set to [unclear]. General → AirPlay The function is activated.
The connection process is extremely simple: on an Apple device, simply press the "Screen Mirroring" button in the Control Center and select your TV. LGThe system will automatically adjust the optimal resolution and frame rate. Importantly, AirPlay 2 supports multiplayer mode and allows you to stream content from apps even when the device's screen is locked.
| Parameter | AirPlay 2 | Miracast | DLNA |
|---|---|---|---|
| Ecosystem | Apple (iOS, macOS) | Windows, Android | All platforms |
| Transmission type | Streaming Video + Mirroring | Full screen mirroring | Media files only |
| Input Lag | Low | Medium/High | None (buffering) |
| Sound quality | High (no compression) | Depends on the codec | Original |
If your TV isn't visible in the AirPlay device list, check your router's firewall settings. Sometimes the ports used by the Bonjour protocol (port 5353) can be blocked by network security settings.
Setting up a DLNA media server to play files
If your goal is not to broadcast your desktop, but to play movies or music stored on the mini-station's hard drive, the best solution is the technology DLNA. Televisions LG have a built-in player Photo & Video, which can scan the network for media servers. You don't need to stream anything in real time; the TV will automatically download the file over the network.
To implement this scheme on a computer with OS Windows Simply enable the "Media Streaming" feature. Go to Settings → Update & Security → Media Streaming and allow access for your TV LGAfter this, a source with the name of your PC will appear in the Home menu on your TV.
- 📂 Open File Explorer in Windows, find the desired folder, right-click and select "Enable media streaming".
- 📺 Launch the app on your LG TV
Photos and VideosorSound. - 🔗 In the list of sources, select the name of your computer.
- ▶️ Folder navigation is done using the remote control, and playback occurs directly from the PC drive.
The advantage of DLNA is that the video decoding load is transferred to the TV's processor, not the mini-station. This allows viewing large 4K files even on low-end laptops. However, the file format must be supported by the TV (usually MKV, MP4, or AVI).
⚠️ Please note: When playing high-bitrate files (e.g., 4K HDR 60 Gbps) over Wi-Fi, buffering pauses may occur. In such cases, even a powerful router may not be able to handle the playback, so it is recommended to use a wired LAN connection or an external hard drive connected directly to the TV's USB port.
Third-party apps for advanced features
Built-in operating system tools webOS Sometimes they can be limited in functionality, especially if you want to stream content from a browser or specific apps. In such cases, third-party solutions like LetsView, AirDroid Cast or the official app LG TV PlusThese programs often offer more flexible quality settings and additional control features.
The operating principle of such applications usually consists of installing the client on the mini-station and the receiver on the TV (if the application is available in the LG Content Store) or using the web interface. For example, for LetsView Simply launch the program on your PC, scan the QR code that appears on your TV screen (via your browser), and the connection will be established.
Using third-party software can bypass some limitations of the Miracast protocol, such as the inability to transmit audio in some Windows configurations or issues with DRM-protected content. However, it's important to remember that free versions of such programs may have session time limits or contain ads.
Diagnosing problems and troubleshooting delays
Even with a perfect setup, a wireless connection is susceptible to external factors. If you notice audio and video out of sync or a choppy picture, first check your Wi-Fi channel load. Using Wi-Fi analyzers on your smartphone can help you find the least congested channel and switch your router to it.
Problems may also be related to the power-saving settings of the network adapter on the mini-station. In Windows Device Manager, find your Wi-Fi adapter, go to Properties, and in the "Power Management" tab, uncheck "Allow the computer to turn off this device to save power." This will prevent short-term connection interruptions.
- 📉 Check your internet and local network speed using Speedtest.
- 🔄 Restart your router and TV to clear the network connection cache.
- 📡 Make sure there are no large metal obstacles between the router and the TV.
- 💾 Update the wireless network adapter drivers on the mini-station to the latest version.
If none of these methods produce stable results, it's possible that the transmitter power in your mini-station isn't strong enough to provide reliable reception at the TV's location. In this case, consider using a Wi-Fi repeater or switching to a wired connection, which remains the benchmark for stability.
Why doesn't my LG TV see my computer in the list of devices?
Most often, the problem lies with the Windows network profile. If the network is marked as "Public," the system blocks device discovery. Switch the profile to "Private" in the Wi-Fi settings. Also, ensure that UPnP and SSDP services are enabled on the router.
Is it possible to play games on the mini-station via Wi-Fi without lag?
For fast-paced shooters and fighting games, a wireless connection, even at 5 GHz, can introduce noticeable input lag. For casual games, strategy games, or RPGs, this is perfectly acceptable. For competitive gaming, an HDMI cable is highly recommended.
Does connecting other devices affect the quality of the broadcast?
Yes, the Wi-Fi channel is shared between all connected clients. If someone on the network is actively downloading files or watching 4K video on another device, there may not be enough bandwidth for screen mirroring, resulting in poor image quality.
