Modern multimedia capabilities allow you to turn your living room into a real cinema, using the resources of your personal computer. Connecting a TV Sony Bravia Connecting to a PC wirelessly eliminates the need to run long HDMI cables across the room. This solution is ideal for watching movies, presentations, or playing games on a large screen without unnecessary visual noise.
The setup process depends on the operating system version on your computer and the model of your TV. Most modern models Android TV And Google TV Sony devices support Miracast and DLNA wireless data transfer standards. This means you don't need to buy additional equipment if both devices are on the same network.
In this article, we'll take a detailed look at all available synchronization methods, from built-in Windows features to specialized apps. You'll learn how to set up 4K video streaming, how to use your TV as a second monitor, and what to do if your devices can't see each other. A key condition for stable operation is the use of a 5 GHz frequency for the router, which provides sufficient bandwidth to transmit heavy video streams without delays.
Equipment preparation and network requirements
Before you begin software configuration, you need to make sure that your local network is ready to handle large amounts of data transfer. Wireless connection Wi-Fi is significantly less stable than wired connections, so signal quality is critical. Both devices—the computer and the Sony TV—must be connected to the same Wi-Fi network.
Please pay attention to the Wi-Fi standard your router uses. To transmit high-resolution images (Full HD or 4K), a module is recommended. Wi-Fi 5 (802.11ac) or newer. If your router is dual-band, make sure both devices are connected to the 5 GHz band, as the older 2.4 GHz band may not be able to handle streaming video.
It's also worth checking that your software is up-to-date. On Sony TVs, firmware updates often add support for new codecs and transmission protocols. Go to the settings menu and check for system updates.
⚠️ Important: If your router is configured for "Guest Network" mode or has AP Isolation enabled, devices will not be able to discover each other. Make sure your router settings allow communication between connected devices.
Menu interfaces may differ depending on the year of manufacture of the TV and the operating system installed (Android TV, Google TV (or Sony's own shell). Always check the exact names of the menu items in the official documentation for your model, as manufacturers often change the menu structure.
Mirroring Windows 10/11 screen via Miracast
The fastest way to display an image from your computer to a Sony TV is to use technology MiracastThis feature is built-in natively in Windows 10 and 11 operating systems and doesn't require any additional software. In this case, the TV acts as a wireless monitor.
To get started, make sure the signal reception function is enabled on your Sony TV. Depending on the model, this may be called "Screen mirroring," "Screen casting," or "Screen mirroring." This option is typically found in the list of signal sources (the Input button on the remote) or in the quick settings.
On your computer, press the key combination Win + KThe "Connection" panel will open on the right, where the system will begin searching for available wireless displays. Your TV should appear in the list. Sony Bravia.
- 📺 Select your TV from the list to start pairing.
- 🖥️ A connection request may appear on the TV screen - confirm it with the remote control.
- ⚙️ Once connected, you can select the operating mode: screen duplication or screen extension.
- 🔊 Check your audio settings so that it plays through your TV speakers, not your PC.
This method is convenient because it allows you to stream any desktop content, including your browser, games, and documents. However, it's important to note that Miracast may introduce a slight input lag, making it less than ideal for fast-paced shooters, but perfectly acceptable for strategy games or watching videos.
☑️ Check before connecting Miracast
Using DLNA to stream media files
If your goal is not to duplicate your desktop, but simply to play a movie or photos stored on your computer's hard drive, the technology DLNA (Digital Living Network Alliance) is ideal. It provides higher image quality and doesn't burden your computer's processor with rendering the entire interface.
To implement this method, you need to set up folder sharing on your computer. In Windows, this is done through the built-in "Media Streaming Settings" feature. Open Control Panel, find the appropriate option, and enable streaming. Your computer will then appear on your TV as a media server.
On your Sony TV, launch the "Media" app (or "Media Player"). Select your computer from the list of sources. You'll see a structure of shared folders. Navigate using the remote control.
The advantage of DLNA is that the TV itself decodes the video file using its powerful processors. 4K HDR ProcessorThis reduces the load on your PC and allows you to play large files without any stuttering, provided your Wi-Fi speed allows it.
| Characteristic | Miracast (Broadcast) | DLNA (Media Server) | HDMI (Wired) |
|---|---|---|---|
| Latency | Medium/High | Low | Minimum |
| Image quality | Depends on compression | Original (no loss) | Original |
| Control | From PC | From the TV remote control | From PC |
| PC load | High | Low | Average |
Why does video lag when streaming?
If video stutters when playing via DLNA, the problem is most often related to Wi-Fi speed. Try disconnecting other devices from the network or lowering the video file's bitrate. Using an Ethernet cable to connect the TV may also help if the Wi-Fi signal is unstable.
Connecting via Google Chrome browser
Owners of Sony TVs with a built-in system Android TV Another powerful tool is the Google Chrome browser on your computer. The browser's "Cast" feature allows you to send a tab or the entire screen to your TV using Google Cast protocols.
This method is especially convenient if the standard Windows connection isn't working or fails. The browser acts as a mediator. Make sure Chrome is updated to the latest version on your PC.
Open your browser, click the three dots in the upper right corner, and select "Cast." The system will search for available devices. You can choose to cast a specific tab, the entire desktop, or an audio tab.
- 🌐 Open the Chrome browser menu and select "Cast".
- 🔍 Find your Sony TV in the list.
- 📂 Select source: tab, desktop, or file.
- 🔊 To transmit sound from your PC, be sure to check the "Broadcast sound" box.
It's important to note that when casting a tab, the video is encoded by the browser. This may result in lower quality than with DLNA, but it ensures excellent compatibility with web content that is copy-protected (DRM) and cannot be played in standard players.
⚠️ Note: When streaming via Chrome, animations and fonts may appear blurry if your PC's screen resolution doesn't match your TV's resolution. For best quality, set your Windows scaling to 100% and the resolution to match your TV's display.
Setting up file sharing (SMB)
A more advanced way to organize a home theater is to use the protocol SMB (Server Message Block). Unlike DLNA, which simply streams content, SMB allows the TV to access the computer's file system as a network drive. This allows you to view movie covers, descriptions, and create playlists.
To configure SMB on Windows 10/11, you need to enable file sharing support. Go to Control Panel → Programs and Features → Turn Windows features on or off. Find and enable "SMB 1.0/CIFS file sharing support" (although for modern TVs, it's better to use SMB v2/v3, which are enabled by default but sometimes require manual configuration in the registry or group policies).
Create a folder for your media files, open its properties, go to the "Sharing" tab, and set up sharing for your account. Remember the network path to the folder (e.g., \\DESKTOP-PC\Movies) and login data (Windows user login and password).
On your Sony TV, in the Media app or a dedicated player (such as VLC for Android, if installed), select Add Network Attached Storage (NAS). Enter your computer's IP address or network name, as well as your username and password.
This method is considered the most stable for viewing large 4K movies with high bitrates, as buffering is more efficient. However, initial access permissions setup in Windows may require careful consideration.
Solving typical problems and diagnostics
Even with proper setup, situations may arise where the computer doesn't see the TV or the connection constantly drops. Most often, the problem lies with Windows security settings or the router's operation.
If your devices are on the same network but can't detect each other, check your network profile in Windows. The network should be marked as "Private," not "Public." For security reasons, the system blocks other devices from being detected in a public profile.
You should also check your antivirus software and firewall. They may be blocking ports required for Miracast or DLNA. Try temporarily disabling protection or adding exceptions for the Windows Media and Projector system services.
- 🔄 Restart your router, computer, and TV—this solves 80% of DNS cache problems.
- 📡 Make sure that frequency splitting (Smart Connect) is not enabled on your router; try explicitly specifying different names for 2.4 and 5 GHz.
- 🛡️ Check if your antivirus is blocking network discovery.
- 📺 Reset network settings on your Sony TV (Settings → Network → Reset network settings).
In some cases, updating the Wi-Fi adapter drivers on your computer can help. Manufacturers often release patches that improve compatibility with various routers and video transmission protocols.
⚠️ Important: If you're using a VPN on your computer, local device discovery won't work. Disable the VPN before attempting to connect to the TV, as it changes the network address and hides the device from the local network.
Questions and Answers (FAQ)
