Modern televisions Sony Bravia They have become powerful multimedia centers, capable of receiving content not only via HDMI but also wirelessly. The ability to stream images from a computer to a large screen opens up new possibilities for watching movies, presentations, and even gaming. Wireless connectivity eliminates the need to run long cables across the room, preserving the aesthetics of the interior.
To successfully implement this task, equipment owners Sony It is necessary to understand the available data transfer protocols. The main standards today are Miracast for screen mirroring and DLNA for streaming media. The choice of a specific method depends on your goals: whether you need to mirror the entire Windows desktop or simply play a video file on your TV.
The setup process may seem complicated only at first glance. In reality, the operating system Windows 10 and 11 has built-in tools that automatically detect compatible displays. In this article, we'll cover all connection methods, potential issues, and solutions so you can enjoy content on your big screen without lag.
Preparing equipment and network
The first and most critical condition for stable wireless streaming is the quality of your local network. Both devices—your computer and your TV—need this quality. Sony Bravia — must be connected to the same access point. If the router broadcasts the network on 2.4 GHz and 5 GHz frequencies with different names (SSIDs), make sure both devices are connected to the same one.
To transmit high-definition video, especially in 4K resolution, the channel bandwidth must be sufficient. Wireless standard WiFi It's susceptible to interference, so the distance between the router and the signal receiver should be minimal. Ideally, if the TV is connected via an Ethernet cable and the PC via WiFi (or vice versa), stability will be higher than if both devices are connected wirelessly.
Make sure the software on both devices is up to date. On TVs Sony On Android TV or Google TV, updates often include fixes for security protocols and wireless drivers. Go to the Settings menu and find the system update section.
⚠️ Attention: Some corporate networks or router guest modes may block direct connections between devices (AP Isolation). If your computer can't see your TV, check your router settings or try sharing the network from your smartphone.
Using the built-in Projection feature in Windows
The easiest way to display an image is to use the native function of the Windows operating system, which is based on the standard Miracast. Televisions Sony Bravia The latest generation of devices support this protocol out of the box, which allows them to work without installing additional software.
To get started, make sure the appropriate app is running on your TV. In the apps menu Sony It may be called "Screen mirroring," "Broadcast," or "Mirror Link." After starting, the TV will enter connection standby mode.
On your computer, press the key combination Win + KThe "Connection" panel will appear on the right, where the system will begin searching for available displays. As soon as your display's name appears in the list, Sony Bravia, click on it. The desktop image will instantly appear on the TV screen.
Miracast Checklist
The operating mode can be changed by calling the projection menu again (Win + P). You have the following options: "Duplicate" (a copy of the screen), "Extend" (a second monitor), "Second Screen Only" (the PC screen goes blank), or "First Screen Only." For watching movies, the "Second Screen Only" mode is most convenient, so you won't be distracted by computer notifications.
Broadcasting via Google Chrome browser
If standard Windows mirroring is unstable or the image quality is not satisfactory, a browser is an excellent alternative solution. Google Chrome. Since many televisions Sony If your phone runs on Android TV or has a built-in Chromecast, this method is often more reliable.
Open your computer's browser and click the three dots in the upper-right corner of the menu. Select "Cast." The browser will scan the network and suggest available devices. You can cast a single tab or your entire desktop.
The advantage of this method is that it optimizes video streaming. When you stream a tab with a video player, the load on your PC's processor can be lower than when mirroring your entire desktop via Miracast. Furthermore, Chromecast copes better with buffering on unstable internet.
Why might streaming not work via Chrome?
If your TV isn't visible in your browser, make sure device discovery is enabled in Chrome's settings. Restarting the Bonjour service on your computer or updating your browser to the latest version can also sometimes help.
To cast your entire screen, select "Cast Desktop" from the source menu. This will allow you to show any application, not just your browser content. However, keep in mind that the screen resolution will be limited by your WiFi connection.
Setting up DLNA for multimedia
Protocol DLNA (Digital Living Network Alliance) is not designed for screen mirroring, but for streaming media content: photos, music, and video files. This is ideal if you want to watch a movie stored on your PC's hard drive using your TV's powerful media system. Sony.
In Windows, you need to enable streaming. Open "Media Streaming Settings" through Control Panel or Search. In the window that opens, click "Turn on media streaming" and make sure your TV is enabled. Sony Bravia is on the list of allowed devices.
After setting up, open the Media Player, Gallery, or Photos app on your TV. Select your computer from the input sources. You'll see the file structure of the folders you've shared.
| Protocol | The main goal | Latency | Picture quality |
|---|---|---|---|
| Miracast | Screen mirroring | Low/Medium | Depends on WiFi |
| DLNA | Playing files | Absent | Original (uncompressed) |
| Chromecast | Streaming from the web | Low | Adaptive |
The main difference between DLNA and other methods is that the TV decodes the video file itself, using its own hardware resources. This means the computer can be turned off (if it's not needed for storage) or busy with other tasks without affecting playback.
Third-party apps for advanced users
Built-in tools don't always provide the necessary flexibility. For example, if you want to stream audio separately or control your computer with a TV remote, there are third-party solutions for these situations, which can be installed both on your PC and in an app store. Google Play on TV.
A popular solution is the app AirScreen or Receiver for AirPlay/DLNA. They emulate signal reception from various sources, making your Sony visible to Apple devices (AirPlay) or providing more fine-grained buffer adjustments. This is especially relevant for older TV models, which may not work well with newer versions of Windows.
Another option is to use media servers such as Plex or KodiBy installing the server component on your PC and the client component on your TV, you get a beautiful interface with movie posters, descriptions, and automatic content sorting. This turns your PC-TV setup into a fully-fledged home theater.
When using third-party software, it's important to ensure proper access rights. The application must have permission to access the local network and file system. Without this permission, sharing folder contents will be impossible.
Solving problems and delays
Even with proper setup, users may experience image artifacts, audio desync, or intermittent connection drops. Most often, the problem stems from radio channel congestion. If neighboring routers, microwave ovens, or cordless phones are nearby, the signal may be distorted.
Try changing the WiFi channel in your router settings. Band usage 5 GHz It's preferable for video streaming, as it's less congested and offers higher speeds, although it has a shorter range. Make sure your router and PC adapter support the standards. WiFi 5 (ac) or WiFi 6 (ax).
⚠️ Attention: Sony TV interfaces are being updated. Menu item layouts may vary depending on the Android TV or Google TV operating system version. Always consult the latest user manual for your specific model.
If you experience audio and video lipsync, check your audio output settings. In the TV menu Sony There's often an "Audio Delay" or "A/V Sync" option that can be adjusted manually. You can also enable audio priority mode in Windows' playback device properties.
