Modern multimedia capabilities allow you to transform your living room into a full-fledged cinema using only your home wireless network. LG People often wonder how to stream content from a laptop or desktop PC to a big screen without the hassle of cables. Fortunately, the ecosystem Smart TV offers a variety of built-in tools to accomplish this task.
There are several proven connection methods, each with its own advantages depending on the file quality and router signal stability. You can use standard protocols. DLNA to play the media library, technology Miracast Screen mirroring or specialized software. The choice of method depends on what exactly you plan to watch: local files or online broadcasts.
Before you begin setup, make sure both devices are connected to the same access point. This critically important condition for most wireless data transfer protocols. If your router supports dual-band mode, it's better to use the network 5 GHz to ensure high-speed video streaming without delays and buffering.
Using Smart Share and DLNA
The easiest way to play a video file is to use the built-in function Smart Share, which is based on the protocol DLNAThis method allows the TV to see shared folders on your computer and play their contents directly. You don't need to download any additional applications if your PC's operating system supports the media server.
To get started, you need to enable streaming in Windows settings. Go to the media player control panel and allow access for your TV. LGThe system will automatically detect the device on the network and prompt you to add it to the trusted list. Once confirmed, a notification will appear on the TV screen.
⚠️ Note: When transferring large files (over 20 GB) via Wi-Fi, playback may become unstable. In such cases, the DLNA protocol may not be able to handle the stream, and it's best to use a wired connection or copy the files to a USB drive first.
After setting up the server, open the app on your TV. Photos and videos or Smart ShareSelect your computer from the source list. The folder structure will be displayed as a tree menu, making it easier to navigate your movie collection. You can control playback with your remote, pausing or rewinding videos.
Screen casting via Miracast and WiDi
If your goal is to show a presentation, web page, or content that is not protected by DRM, then the technology is ideal MiracastOn TV LG This feature is often called "Wireless Monitor" or "Screen Share." It allows you to fully mirror your computer monitor's image to your TV screen in real time.
To connect, press the button on the remote control Input or find the shortcut in the application launcher menu Screen ShareLaunch the app, and the TV will go into connection standby mode. On a computer running Windows 10 or 11, press the key combination Win + K to search for available wireless displays.

☑️ Check before connecting Miracast
It is important to understand the difference between this method and DLNA. When using Miracast The computer encodes the video stream on the fly, which puts a strain on the processor. If you're watching a heavy 4K movie, the laptop may start to overheat and the fan may become noisy. For watching movies, it's best to use direct file transfer methods rather than screen mirroring.
Setting up a media server in Windows for LG TV
For stable operation of the function Smart Share It's important to configure the sharing settings correctly in the operating system. Users often encounter a problem where the TV simply "doesn't see" the computer, even though both devices are connected to the router. The problem lies in the network profile, which is set to "Public."
Change the network profile to "Private" in Windows Settings. This will open the necessary ports for local data exchange. Then, go to "Media Streaming Settings" and ensure "Allowed" is checked. You can also set a device name here to easily identify it in the TV list.
If you can't configure access using standard Windows tools, you can use third-party software. Popular server programs such as Plex, Universal Media Server or Kodi, provide more flexible transcoding settings. They can convert video on the fly if the TV doesn't support the file format.
| Parameter | Description | Recommended value |
|---|---|---|
| Protocol | Data connection type | DLNA / UPnP |
| Video formats | Supported containers | MP4, MKV, AVI |
| Audio codec | Audio track format | AC3, AAC, DTS |
| Permission | Maximum stream quality | Up to 3840x2160 (4K) |
Why doesn't the TV see the folders?
If the folders don't appear after setting up the server, check your Windows Firewall. It may be blocking incoming connections to the media server service. Add an exception for the "Media Streaming" app in your network security settings.
Third-party streaming apps
Standard operating system tools don't always provide the required quality or convenience. In such cases, specialized applications developed for both PCs and platforms come to the rescue. webOS (LG TV operating system). They allow you to control playback directly from your smartphone or computer keyboard.
One of the most popular solutions is a bundle of programs VLC Media Player on your computer and the built-in receiver on your TV. After opening the file in VLC, select "Playback" → "Render" and find your TV. This allows you to stream directly, bypassing the complex settings of shared folders.
Another powerful tool is the app AllConnect or BubbleUPnPThey create a user-friendly interface for managing your media library. You can create playlists, add subtitles, and select audio tracks. These programs often have a more responsive interface than a standard TV remote.
⚠️ Please note: App interfaces and the webOS operating system are subject to update. Button locations and menu names may differ from those described in the instructions. Always refer to the current prompts on your device's screen.
For users who prefer cloud storage, there are client apps for Smart TVs. After installing the client Google Drive, Dropbox or Yandex Disk On your TV, you can play video files directly from the cloud, bypassing your computer. This frees up your PC's resources and allows you to watch content even after turning it off, as long as the file is already uploaded to the cloud.
Solving buffering and quality issues
When wirelessly transmitting high-resolution video (Full HD and 4K), users often experience stuttering or audio desync. This indicates insufficient Wi-Fi bandwidth. Signal loss can occur due to distance, walls, or interference from neighboring networks.
The first step should be optimizing the router's position. Make sure there are no thick concrete floors or metal structures between the computer, router, and TV. If the router is dual-band, force all devices broadcasting to the same frequency. 5 GHz, which is less congested and provides speeds.
It's also worth checking the power-saving settings of your computer's network adapter. Windows may try to conserve power by reducing signal strength or disconnecting the connection when idle. In Device Manager, find your Wi-Fi adapter, go to Properties, and in the Power Management tab, uncheck the box next to Allow the device to turn off.
Comparison of connection methods and their features
Choosing the optimal transmission method depends on your specific needs and technical equipment. Each method has its own strengths and weaknesses, which must be considered when setting up a home theater. Below is a comparison of the main technologies.
