Modern technology allows you to transform your living room into a true cinema, eliminating unnecessary wires and complex connections. The question of how to watch movies from your computer on your TV via LG Wi-Fi is especially relevant for Smart TV owners who want to enjoy content on the big screen without HDMI cables. This is not only convenient but also aesthetically pleasing, as it helps keep the room's interior looking tidy.
The setup process may seem complicated at first glance, but modern TV operating systems and firmware are highly automated. You don't need to be a software engineer to set up wireless data transfer. Simply follow the clear steps outlined in this article to start playing video files in minutes.
We'll cover all the main methods, from built-in Windows features to third-party apps that guarantee a stable picture. It's important to understand that transmission quality depends on your router's speed and supported standards. Wireless network It should be powerful enough to transfer large, high-resolution files without lag or buffering.
Preparing equipment and network for broadcasting
Before configuring the software, you need to ensure the hardware is physically ready. Both devices—your personal computer and your LG TV—must be connected to the same local network. This is a fundamental requirement, without which device discovery is impossible.
It is recommended to use Wi-Fi standard 5 GHz, if your router and receiver modules support this range. It provides higher throughput, which is critical for transmitting 4K or HDR video. The 2.4 GHz band can be subject to interference from neighboring networks and household appliances, resulting in choppy images.
Make sure the Smart TV function is enabled on your TV and the wireless module is activated. On some LG models, you need to press a special button on the remote control to activate WiFi; this button is often marked with an antenna icon or the words Smart.
⚠️ Attention: If your router distributes two networks with the same name (Dual Band), make sure that both the PC and TV are connected to exactly one of them, and not separated by different frequencies, otherwise they may not "see" each other on the local network.
It is also worth updating the TV firmware to the latest version through the menu Settings → All settings → Support → Software updateManufacturers frequently release patches that improve the stability of network protocols.
DLNA Method: Built-in Windows and LG function
The simplest and most native data transfer method is using DLNA technology. In the Windows operating system, this feature is implemented through a media server, which may already be enabled by default. LG TVs are equipped with a built-in player that can recognize such servers without installing additional software.
To get started, open the Media Control Panel. In Windows 10 and 11, this functionality is often hidden or simplified, so it's best to use the classic path via Folder Options. Go to Control Panel → Network and Internet → Network and Sharing Center.
Here, you need to select the option to change sharing settings. Make sure network discovery and file sharing are enabled. Without these settings, the LG TV simply won't have access to your hard drive.
- 📁 Open File Explorer and find the folder with your movies.
- 🖱️ Right-click on the folder and select "Share with" → "Individual people".
- 👤 Add the user "Everyone" or the current user and set the permissions to "Read and Write".
- ✅ Click the "Share" button to complete the access rights settings.
After that, press the button on the LG TV remote control Input Or go to the Smart TV main menu. Find the "Media" app (or "Photos & Videos" or "Videos" depending on your webOS version). Your computer should appear in the list of sources.
After selecting a computer, you'll see a list of shared folders. Navigate using the remote control. TV interface Allows you to sort files by date, name or type, making it easier to find the movie you need in a large collection.
Using the LG TV Plus app and third-party players
If standard Windows tools are unstable or don't support certain subtitle formats, it might be worth turning to specialized software. Official app LG TV Plus (formerly LG Smart View) allows you to not only control your TV, but also stream content.
However, third-party media server programs like Plex, Kodi, or Universal Media Server offer more flexible options. They automatically download movie covers and descriptions and properly process audio tracks. Installing such a server turns your PC into a full-fledged media library.
Let's look at the setup using a popular free solution as an example. After installing the program, you need to add the paths to the video file folders to the library. The program will index the content and create a beautiful catalog.
⚠️ Important: When using third-party servers, ensure that Windows Firewall isn't blocking incoming connections for the new app. When you first launch the app, the system will ask for permission to access the network—select "Private Network" or "Home Network."
On your LG TV, find and install the appropriate client (for example, Plex for LG) in the Content Store. Launch the app on both your TV and computer, signing in with the same account. Syncing will occur automatically via the cloud or your local network.
The advantage of this method is that it supports transcodingIf the TV cannot read a certain video or audio format, the computer will transcode the stream on the fly into a compatible format, ensuring smooth playback.
☑️ Check DLNA settings
Miracast Technology: Cloning Your Computer Screen
Unlike DLNA, which only transfers a file, Miracast technology lets you cast your entire computer screen or a specific window to an LG TV. This is ideal if you're watching a movie in a browser on a website that doesn't directly support DLNA, or if you want to show a presentation.
In Windows 10 and 11, this feature is built in and is called "Connect." Press the key combination Win + KThe system will begin searching for available wireless displays. Make sure the "Screen Share" app is running on your LG TV, which is usually located in the top menu or app list.
Once the device is detected, select your TV from the list. A connection confirmation prompt may appear on the TV screen—allow it with the remote. The image from your PC monitor will appear on the big screen.
- 🖥️ Click
Win + PTo select the projection mode: "Duplicate" or "Expand". - 🔊 The sound will also be transmitted to the TV if you select it as the default playback device.
- 🎮 In extended screen mode, you can continue working on your computer while a movie is playing on TV.
It is important to note that when using Miracast, the load falls on the WiFi adapter and processor, since the video stream is encoded in real time. Input lag (input lag) is higher in this mode, so you won’t be able to play dynamic games, but it’s quite acceptable for watching movies.
What should I do if the mouse cursor is visible on the TV?
In mirroring mode, the cursor is always visible. To hide it, launch the video player in full-screen mode or use the "Second Screen Only" mode in the projection menu (Win+P). This will dim the image on the PC monitor but leave it on the TV.
Comparison of connection methods and their characteristics
Choosing the optimal method depends on your goals and technical equipment. Each method has its own advantages and disadvantages, which should be considered before setting up. Below is a comparison table of the main characteristics.
| Characteristic | DLNA (Media Server) | Miracast (Broadcast) | Third-party apps (Plex) |
|---|---|---|---|
| Picture quality | Original (no loss) | Depends on the WiFi signal | Original or transcoding |
| Control | From the TV remote control | From a PC keyboard/mouse | From a remote control or smartphone |
| PC load | Minimum | High (coding) | Medium/High |
| Subtitle support | Depends on the format | As on the PC screen | High (built-in) |
As the table shows, DLNA is best for simply viewing downloaded files. If the content is online and not DRM-protected, screen cloning is more convenient. The DLNA protocol does not transmit desktop images, it only broadcasts media files.
For users who value a beautiful interface and movie descriptions, third-party servers like Plex are the undisputed leader. They create the feeling of using a professional online cinema with its own library.
Troubleshooting Buffering and Connection Issues
Even with proper setup, users may encounter problems: video stutters, audio lags behind the picture, or the computer doesn't recognize the TV. Most often, the cause is an unstable WiFi signal.
Try rebooting your router by unplugging it for 10-15 seconds. This will clear the device's cache and select a less noisy channel. Also, make sure there are no thick walls or metal structures between the router and the TV that could block the signal.
If the problem persists, check your antivirus settings. Some security suites may block local connections, deeming them suspicious. Add your home network to the trusted list.
⚠️ Please note: Smart TV interfaces and Windows operating system versions are updated regularly. The location of menu items or function names may differ slightly from those described in the instructions. Always consult the latest support materials on the official website of your device manufacturer.
If all else fails, try connecting your computer to the router via a LAN cable. This will ensure maximum data transfer speed and connection stability, eliminating the possibility of radio interference.
Frequently Asked Questions (FAQ)
Is it possible to stream videos from your phone to your LG TV the same way as from a computer?
Yes, most modern Android and iOS smartphones support Screen Share or have a built-in "Cast" feature. The principle is the same: the devices must be on the same WiFi network. You can also use the LG ThinQ app to manage and share photos and videos.
Why can the TV see the computer but not open folders?
The issue is most likely related to Windows permissions. Check that the "Turn off password-protected sharing" option is enabled in the sharing settings, or that the account you're logged into Windows with has a password. Without a password, access to the shared folder may be blocked.
Does LG support playing MKV and HEVC files via WiFi?
Most modern LG models running webOS 4.0 and higher support these formats natively. However, large 10-bit HEVC (H.265) files may require PC-side transcoding via a Plex server, as the TV's built-in decoder may not be able to handle the higher bitrate.
How to improve sound quality when transmitting via Miracast?
If your TV's built-in speakers don't meet the requirements, connect an external speaker system or soundbar to the TV's optical output or via Bluetooth. The Miracast protocol itself transmits audio digitally without loss of quality, so the problem usually lies with the playback device.
