Modern Smart TV LG TVs offer a wide range of multimedia entertainment options, allowing you to stream content from other devices without the hassle of cables. Wirelessly streaming video from a personal computer to a large screen is not only convenient but often essential for comfortable movie viewing or photo sharing. Wi-Fi Direct and streaming standards make this process accessible even to inexperienced users, provided they know the correct sequence of actions.
There are several proven methods for accomplishing this task, each with its own specific features depending on your TV model and computer operating system. You can use built-in Windows features, third-party software, or specialized streaming protocols. Understanding the differences between these methods will help you choose the best option for your specific situation and the quality of your existing wireless network.
Before you begin setup, make sure both devices are connected to the same network, as this is a fundamental requirement for most synchronization methods. In this article, we'll cover the various technologies in detail, their advantages and disadvantages, and solve common connection issues. Proper setup will allow you to enjoy high-definition content without lag or image artifacts.
Preparatory stages and network requirements
For stable video streaming, the quality of your wireless connection is critical. It is recommended to use a router operating within the range 5 GHz, as it provides higher throughput compared to the 2.4 GHz frequency. This is especially important when streaming video in high resolution 4K or 1080p with high bitrates, where the bottleneck of the communication channel can cause interruptions.
Make sure that on your LG Smart TV The wireless function is enabled and the external connection mode is activated. The interface may differ on older TV models, but basic settings are usually found in the network or device connection menu. The computer must also have a working Wi-Fi adapter with up-to-date drivers that support the standards. IEEE 802.11n or newer.
Sometimes antivirus software or the built-in Windows firewall can block attempts to detect the TV on the local network. In this case, you need to add an exception for the media service or temporarily disable protection for diagnostics. Checking basic connectivity between devices is the first step to successful setup.
⚠️ Note: If your router distributes two different networks (2.4 GHz and 5 GHz) with different names, make sure that both the PC and TV are connected to the same frequency, preferably 5 GHz for video.
Using Connect to a Wireless Display in Windows
Windows 10 and 11 operating systems have a built-in screen mirroring tool that is based on technology MiracastThis method allows you to stream not only video files but also your entire desktop, which is convenient for presentations or games. No additional software is required to launch this feature; simply press a key combination. Win + K on the keyboard.
A list of available devices will appear in the menu on the right, including your LG TV. When connecting for the first time, the system may prompt you to confirm access on the TV screen. Once the connection is established, the image from your computer monitor will appear on the big screen with minimal delay.
It's worth keeping in mind that this method puts a significant load on your computer's processor and graphics card, as it encodes the video stream in real time. If you're simply planning to watch a movie, it's best to use the other methods described below to avoid impacting system performance. However, for sharing an interface or photo album, Miracast is ideal.
☑️ Check Miracast
Streaming via DLNA and LG's built-in media player
Protocol DLNA (Digital Living Network Alliance) is a standard for transmitting multimedia content over a home network. Unlike mirroring, the file itself is streamed, and the TV uses its own decoders for playback, reducing the load on the computer. In Windows, this feature is called "Media Streaming" and is activated through the Network and Sharing Center.
You can use the standard Windows Media Player or more advanced alternatives to manage the process. Open the video file, right-click, and select "Cast to Device," then select your LG TVThe TV will automatically launch the built-in player and begin playback.
The advantage of this method is the ability to control playback (pause, rewind) from both the TV remote and the computer. Furthermore, image quality doesn't depend on the power of the PC's Wi-Fi adapter during playback, as the file is streamed directly to the TV. This is the most energy-efficient way to watch movies.
| Characteristic | Miracast (Screen Casting) | DLNA (Streaming) | Third-party software |
|---|---|---|---|
| PC load | High | Low | Average |
| Remote control | Limited | Complete | Complete |
| Image quality | Depends on the signal | Original file | Customizable |
| File formats | Any (as on the screen) | Supported TVs | Any (with conversion) |
Using third-party programs: Plex and Kodi
If standard tools are not enough or support for specific subtitle and audio track formats is required, it is worth turning to specialized software. Plex Plex is a powerful media system that organizes your file library, adds covers and descriptions, and turns your PC into a fully-fledged home server. The Plex app is installed on your LG TV from the LG Content Store.
Program Kodi It also offers extensive customization options and supports a huge number of plugins. Installing the server on your computer and the client on your TV allows you to create a flexible content management system. Such solutions are especially useful if you have a large collection of movies and TV series that you want to organize.
Using third-party software allows you to stream video even over the internet while away from home, provided you set up remote access correctly. However, initial setup and stable operation within the network require a deeper dive into technical details than with built-in features. However, you gain maximum control over the process.
⚠️ Important: When using server applications (Plex, Emby), make sure that Windows Firewall is not blocking the ports used by the program (usually 32400 for Plex).
Why might Plex not be able to see files?
Often, the issue lies in folder permissions. Make sure the user running the Plex server has read access to the video folders. Also, check that your antivirus software isn't flagging media files as threats or blocking access to them.
AirPlay 2 technology for macOS and iOS users
Computer owners MacBook and Apple devices will appreciate the support of the technology AirPlay 2, which is built into many modern LG TV models. This technology allows you to stream your screen or specific video files with quality optimized for the Apple ecosystem. To connect, simply click the AirPlay icon in the macOS menu or in the Photos app.
The system automatically detects the TV on the network and prompts you to connect. Key features include support for multi-room audio and synchronization with other Apple devices in the home. Video streaming quality via AirPlay 2 is typically very high, with minimal compression.
If your TV model doesn't natively support AirPlay 2, you can use third-party emulator apps installed on the TV itself from the app store. These create a virtual receiver compatible with Apple devices. This expands the capabilities of older, yet still functional, Smart TV models.
Solving common connection problems
Despite the simplicity of the technology, users often encounter situations where the computer can't see the TV or the connection constantly drops. First, check if the feature is enabled. Network Discovery (Network discovery) in Windows network settings. Without this, the system simply won't search for other devices on the local network.
It is also worth updating the TV software through the menu Settings → All settings → Support → Software updateManufacturers regularly release patches to fix communication protocol errors. Sometimes, simply restarting the router and both devices, which resets the network settings cache, helps.
If video playback is choppy, try lowering the file's bitrate or switching your router to a less congested channel. Interference from nearby networks or microwave ovens can significantly impact the stability of data transmission over the air. In critical situations, using an HDMI cable remains the most reliable, albeit less convenient, option.
⚠️ Note: The menu interface on LG TVs may vary depending on the webOS version. If you don't see this option, please refer to the user manual for your specific model.
Why isn't my LG TV showing up in the list of available devices?
Most often, the problem is that the devices are on different subnets (for example, if guest Wi-Fi mode is enabled) or on different router frequencies. Also, check if the router is configured to restrict data exchange between clients (AP Isolation).
Is it possible to stream video from Android phone to LG TV?
Yes, most modern Android smartphones support Smart View or Cast, which works similarly to Miracast. You can also use the LG TV Plus app to manage and transfer photos and videos.
Does video streaming affect internet speed?
When using DLNA and local methods, traffic flows within your home network and doesn't consume internet bandwidth. However, if you stream online videos (YouTube, Netflix) from your PC to your TV, your bandwidth usage is normal.
