Modern technology has transformed content viewing into an entertainment center, with a large television becoming the main screen and a regular laptop serving as the signal source. LG People often wonder how to quickly and without unnecessary wires display an image or video file on the panel Smart TVFortunately, built-in wireless data transfer protocols make this possible in just a few clicks, without the need for complex router settings or the purchase of additional equipment.
In this article, we will examine in detail all available connection methods: from native operating system functions Windows to using specialized applications and cloud services. You will learn how to set up Miracast For screen mirroring, how to use the protocol DLNA for playing the media library and what are the nuances of working with AirPlay 2 for Apple technology users.
The main advantage of a wireless connection is that there are no cable length restrictions and you can move freely around the room. However, for stable operation, it is necessary that your Wi-Fi router supported high-bandwidth standards, especially if you plan to stream content in high definition 4K or 8KBelow are step-by-step instructions to help you set up the perfect home theater.
⚠️ Important: For all the methods described below to work correctly, the laptop and TV must be connected to the same local Wi-Fi network. Different frequencies (2.4 GHz and 5 GHz) within the same network are usually not an obstacle, but different subnets can block device detection.
Checking compatibility and preparing equipment
Before you begin setting up your broadcast, you need to make sure your equipment is technically ready for operation. Most modern TVs LG with function Smart TV (webOS platform) support wireless media streaming out of the box. However, the age of the model and the operating system version may affect the protocols available. For example, support AirPlay 2 appeared only in 2019 and newer models.
A stable wireless signal is crucial. If the router is located far from the TV or behind thick walls, picture quality may suffer, including audio delays, image artifacts, or complete desynchronization. For HD video streaming, it's recommended to use the [Wavelength] band. 5 GHz, which provides higher data transfer rates compared to 2.4 GHz.
It's also worth checking for software updates on both devices. Manufacturers frequently release patches that improve compatibility with new encryption standards and communication protocols.

- 🔗 Make sure both devices are connected to the same network (SSID).
- 🔄 Check for the latest firmware updates for your LG TV.
Streaming via Miracast (Wireless Display) in Windows
The easiest and fastest way to display images from your laptop on your TV LG without using third-party programs - this is technology MiracastIn the operating system Windows 10 And Windows 11 It's implemented as a "Connect" or "Project" function. In this case, the TV acts as a wireless monitor, completely duplicating what's happening on your computer screen.
To activate this mode on your TV LG Typically, there's no need to launch a separate app, as the feature is built into webOS. However, on some models, you may need to open an app. Screen Share or Connecting to a mobile device in the list of running programs. After this, the TV will go into connection standby mode.
On your laptop, press the key combination Win + KA sidebar will appear on the right, searching for available wireless displays. Select your TV from the list. If this is your first time connecting, a connection confirmation prompt may appear on the TV screen, which you'll need to accept with your remote control.
Once paired successfully, the image from your laptop will appear on the TV. You can change the projector mode by pressing Win + PThe available options are: "PC screen only", "Repeat" (mirroring), "Extend" (the TV will become a second desktop), and "Second screen only" (the laptop screen will go dark).
⚠️ Please note: Miracast technology is sensitive to interference. If you experience video stuttering, try moving closer to the router or turning off other devices that are actively consuming bandwidth (torrents, downloads).
☑️ Miracast setup checklist
Using DLNA to Play Your Media Library
If your goal is not to broadcast your entire desktop, but simply to launch a movie or TV series stored on your laptop's hard drive, then the protocol DLNA (Digital Living Network Alliance) is ideal. Unlike Miracast, the TV decodes the video file itself, receiving only the data stream over the network, reducing the load on the laptop and often resulting in smoother playback.
To implement this method, you need to enable the media streaming feature on your computer. Windows This can be done through "Media Streaming Settings" in the Control Panel or through the Settings app under "Network & Internet." You'll need to allow access to media files for your TV. LG.
After setting up on your TV, launch the app Photos and videos (or similar, for example, Smart Share (On older models). Select your computer from the source list. You'll see folders containing videos, music, and photos available for playback. Navigation is handled using the remote control.
An alternative and often more convenient way is to use third-party media servers such as Plex, DLNA Server or KodiThese programs automatically scan your hard drive, find metadata (movie covers, descriptions, actors) and create a beautiful library that your TV LG will be seen as a separate device on the network.
Why can't the TV see files via DLNA?
Often, the problem lies in the video file format. If the file has the .mkv extension and uses the HEVC (H.265) codec, and your older LG TV doesn't support this codec natively, the file may display but not play. In this case, installing a third-party player on the TV or transcoding the video may help.
AirPlay 2 support for MacBook users
Laptop owners MacBook will appreciate the native support of the technology AirPlay 2 in modern televisions LGThis feature allows you to not only broadcast the image, but also transmit sound to external speakers or a subwoofer if they are connected to the ecosystem. AppleAirPlay 2 support is built into LG TVs released since 2019, as well as some earlier models after a firmware update.
To get started, make sure AirPlay is enabled on your TV. It's located in the menu. Settings → Connection → AirPlay and HomeKit setupHere you can also set an access code (password) that will be requested the first time a new device is connected, increasing the security of your network.
On a laptop Mac Open Control Center from the menu bar and select Screen Mirroring. Select your TV from the list of available devices. LGIf you only want to stream video from your browser Safari or player, just click the AirPlay icon directly in the video player interface.
AirPlay 2 also lets you use your TV as a second monitor, extending your desktop rather than just mirroring it. This is convenient for working on documents or checking email on a larger screen while you're working on your laptop. Image quality remains high, with minimal latency.
Third-party applications and cloud services
Built-in operating system tools don't always work perfectly or may have limited functionality. In such cases, third-party apps that can be installed directly on the TV come to the rescue. LG (through the store LG Content Store), and on a laptop. One of the most popular solutions is the application TV Plus or universal controllers.
Another effective method is to use cloud storage. If your video files are uploaded to Google Drive, Dropbox or OneDrive, you can install the corresponding application on your TV LGBy logging into your account, you'll have access to all your files directly from your TV, bypassing your laptop. This frees up your computer and eliminates network protocol hassles.
For advanced users who want to set up a full-fledged home media center, the bundle is ideal Plex Server on a laptop and an application Plex on the TV. The server part scans files, adds posters, descriptions, subtitles, and can even transcode videos on the fly if the TV doesn't support the source file format.
| Method | Best use | Delay | Quality |
|---|---|---|---|
| Miracast | Presentations, browser, games | Medium/High | Depends on the signal |
| DLNA | Watching movies from memory | Minimum | Original (uncompressed) |
| AirPlay 2 | Apple users | Low | High |
| HDMI cable | Games, 4K HDR content | Absent | Ideal |
⚠️ Please note: The LG Content Store interface may vary depending on your region and TV year. Some apps may not be available for direct download on older webOS models.
Solving common connection problems
Despite the simplicity of setup, users may encounter difficulties. One of the most common issues is that the laptop doesn't see the TV in the list of available devices. This is most often due to network profile settings in Windows. Make sure your network is marked as "Private" and not "Public." In a public profile, the system blocks detection of other devices for security reasons.
Another common issue is audio and video desynchronization. This is typical for wireless video streaming technologies. If the delay becomes noticeable, try lowering the display resolution in your laptop's display settings or switching to a wired connection if image quality is critical.
Codec issues are also worth mentioning. The TV may see the file via DLNA, but return an "Unsupported format" error. In this case, file conversion on the laptop side before sending or using a server with a transcoding function (like Plex) will solve the problem.
Why isn't my LG TV showing up in the wireless display list?
There could be several reasons: AP Isolation mode enabled on the router, different subnets, outdated Wi-Fi drivers on the laptop, or a TV firmware update. Also, check if your antivirus or Windows Firewall is blocking network discovery.
Is it possible to play games on a laptop via Wi-Fi on a TV?
Technically, this is possible via Miracast, but input lag will make fast-paced shooters or fighting games uncomfortable. For more sedate strategy or card games, a lag of 100-200 ms may not be as noticeable. For gaming, it's better to use an HDMI cable.
How to improve picture quality during wireless broadcasting?
Move closer to the router, close bandwidth-consuming apps on other devices, and ensure your laptop isn't in power-saving mode, which could limit Wi-Fi performance. Disabling background Windows updates also helps.
