Modern technologies make it possible to create multimedia entertainment systems without unnecessary wires, transforming the living room into a true cinema. Connecting an ASUS laptop to an LG TV wirelessly opens access to content from the big screen, making it especially convenient for watching movies, presentations, or gaming. This approach is becoming increasingly popular as users strive for minimalism and ease of control over digital devices in their homes.
The basis for such interaction is wireless data transmission standards such as Miracast and DLNA, which are built into Windows operating systems and Smart TV firmware. Wireless connection This eliminates the need to run long HDMI cables across the room, preserving the aesthetic appearance of the interior. However, for stable operation, it is critical that both devices are on the same local network and support the necessary data exchange protocols.
In this article, we'll take a detailed look at all available synchronization methods, from built-in Windows features to specialized software. You'll learn how to set up Miracast For screen mirroring or DLNA for video streaming. Properly configuring your router and TV will help avoid image lag and audio desync.
Preparing equipment and a Wi-Fi network
Before you begin configuration, you need to make sure that your network equipment is ready to handle heavy multimedia traffic. Router It should work reliably, preferably in the 5 GHz band, as this standard provides higher throughput than 2.4 GHz. If your router is old or located far from the TV, signal interruptions and reduced picture quality are possible.
Both devices are laptops. ASUS and TV LG Smart TV devices must be connected to the same Wi-Fi network. This is a fundamental requirement for all wireless connection methods. If you have a dual-band router, make sure both devices can see each other, even if they're connected to different frequency bands (although ideally, the frequencies should match).
⚠️ Note: If your router has the "AP Isolation" feature, devices on the network will not be able to see each other. This option must be disabled in the router settings under the Wireless Network section.
Also check your TV software. Go to the menu Settings → All settings → General → About TV and make sure you have the latest version of webOS installed. Firmware updates often add support for new codecs and fix connection issues.
Using Miracast (Wireless Display) technology
The most popular and universal way to broadcast your laptop screen to a TV is with the technology Miracast, which is implemented in Windows 10 and 11 as the "Wireless Display Connection" feature. This method allows you to fully mirror the image from your ASUS monitor to the larger LG screen, making it ideal for showing presentations or browsing the web.
To get started, press the Input button on your LG TV remote and find the "Screen Share" or "Mobile Device Connection" app. On some models, this may simply be called "Wireless Display." Once launched, the device name will appear on the screen, and a connection message will appear.
☑️ Check before connecting Miracast
Now let's move on to the ASUS laptop settings. Press the key combination Win + K on the keyboard. The "Connection" panel will open on the right, where the system will begin searching for available displays. Select your LG TV from the list.
A connection confirmation message may appear on the TV screen. Use the remote control to select "Accept" or "Allow." The Windows desktop image will then appear on the TV. You can change the operating mode in the menu. Settings → System → Display, selecting the "Duplicate" or "Extend" mode.
What to do if the laptop doesn’t see the TV?
If the search yields no results, try temporarily disabling your antivirus or Windows Firewall. Also, make sure the Wi-Fi adapter drivers on your ASUS laptop are updated to the latest version from the manufacturer's official website. Restarting the SSDP Discovery Service in Windows (services.msc) can sometimes help.
Stream media via DLNA
If you don't need to duplicate the entire screen, but just want to run a movie or show photos stored on your laptop's hard drive, it's better to use the protocol DLNAThis method is less demanding on system resources and allows you to control playback directly from the TV remote control.
In Windows, this feature is implemented through "Media Streaming." To enable it, open "Streaming Options" in the "Multimedia" menu or through Control Panel. Make sure "Allow media streaming" is checked.
Next, you need to share the folders whose content you want to see on your TV. Go to File Explorer, right-click the folder containing your movies or photos, select "Share to," and select your LG TV. The system will automatically add this path to your media library.
On your LG TV, open the Photos & Videos app (or Media Player). Select your ASUS laptop from the list of sources. You'll see the folder structure and files available for playback. DLNA Supports most popular formats, but specific codecs may require a third-party player.
Using AirPlay 2 for MacBook and iOS Owners
While the main focus is on ASUS laptops, many Apple users are also looking for ways to connect to LG TVs. Modern LG models with webOS 4.0 and higher support the technology built-in. AirPlay 2This allows you to mirror your iPhone, iPad, or MacBook screen or content without installing additional apps.
The connection process is extremely simple: make sure your Apple device and TV are on the same Wi-Fi network. On your Apple device, open Control Center and select Screen Mirroring (the icon with two rectangles). Select your LG TV from the list of available devices.
If this is your first connection, a four-digit code will appear on your TV screen. Enter it on your Apple device. Once confirmed, your MacBook or iPhone screen will instantly appear on your TV. This method isn't suitable for ASUS laptops, as Windows doesn't natively support AirPlay, but Apple owners will appreciate the feature.
| Characteristic | Miracast (Wi-Fi Direct) | DLNA | AirPlay 2 |
|---|---|---|---|
| Transmission type | Screen mirroring | Streaming video/photos | Dubbing and streaming |
| Router dependency | Low (direct connection) | High (via network) | High (via network) |
| Windows support | Native | Native | Third-party software is required |
| Picture quality | Depends on the signal | Original (uncompressed) | High |
Third-party sync apps
Built-in Windows tools don't always work perfectly, especially if the Wi-Fi adapter drivers on your ASUS laptop conflict or the router doesn't handle multicast traffic correctly. In such cases, third-party programs can often provide a more stable connection and additional features.
One of the most popular solutions is the application LetsView or ApowerMirrorThey are available for installation on a PC or as apps in the LG Content Store (although more often, the app is installed only on the PC, with the TV acting as a receiver via a built-in protocol). These programs not only allow you to mirror your screen but also control your computer with a remote control and transfer files.
Another option is to use the Google Chrome browser. If you have this browser installed, you can cast a tab or your entire desktop. Click the three dots in the upper right corner, select "Save and Share" (or "Cast"), and select the Chromecast built-in device (which is built into most LG TVs).
⚠️ Warning: When using third-party programs, make sure you download them from the developers' official websites. Installing software from untrusted sources can lead to malware infection on your computer.
For advanced users, installing a server would be an excellent solution. Plex to your laptop. This will transform your ASUS into a powerful media server with a beautiful interface, movie posters, and descriptions. The Plex app for LG TV is one of the most stable and functional in its class.
Troubleshooting and Delays
Despite the convenience of wireless technology, users often encounter problems: the image flickers, the audio lags behind the video, or the connection constantly drops. Most often, the cause is Wi-Fi congestion or a weak signal.
Try moving your laptop closer to the router or, conversely, moving the router closer to the TV. If you're using the 2.4 GHz band, switch to 5 GHz, as it's less susceptible to interference from microwave ovens and neighboring networks. Also, check if your laptop has any background downloads that are hogging bandwidth.
If you're experiencing audio lag, try changing your laptop's audio driver settings. In some cases, disabling sound effects or changing the audio format in the playback device properties to 16-bit, 44100 Hz may help.
As a last resort, if your wireless connection still isn't stable enough for gaming or 4K video, consider using a wired HDMI connection. This will ensure maximum quality and eliminate lag, although it will require some cabling.
Why doesn't the TV see the laptop when searching?
The most common issue is that the devices are on different networks (for example, one is connected to a guest Wi-Fi network and the other to the main network). Network discovery may also be blocked in Windows. Check the network profile: it should be "Private" and not "Public."
Can you play games on TV via Wi-Fi?
For fast-paced games, a wireless connection via Miracast isn't suitable due to input lag. However, for strategy or card games that don't require millisecond precision, it's perfectly possible. For a comfortable gaming experience, it's best to use an HDMI cable.
Does connecting a TV affect internet speed?
When using DLNA or streaming from a laptop, traffic flows within your local network and doesn't consume your ISP's internet bandwidth. However, if you watch online videos (YouTube, Netflix) through a streaming browser, your internet bandwidth is used as normal.
