Modern home entertainment systems are no longer isolated devices, and integration computer with a large screen has become the de facto standard. Users often look for a way to display images from a laptop or desktop PC on a panel. Sony Bravia without the use of unnecessary cables that spoil the interior and restrict freedom of movement. Wireless connection via Wi-Fi solves this problem elegantly, allowing you to stream movies, presentations or games with minimal latency.
In this guide, we'll cover all available synchronization methods in detail, from standard Windows protocols to specialized Sony apps. You'll learn how to set up DLNA for multimedia and Miracast for screen mirroring, and you'll also understand which option is best for your TV model and operating system.
Before you begin setup, make sure both devices are on the same local network. This is a basic requirement for any type of wireless communication. If the router broadcasts the network at frequencies 2.4 GHz And 5 GHz, try to connect both your TV and computer to the same frequency for maximum stability.
Preparatory stage and network requirements
The success of a wireless connection directly depends on the signal quality and correct router settings. Modern TVs Sony with the operating system Android TV or their own interface require a stable IP address to be discovered by external devices. Make sure AP client isolation isn't enabled on your router, which blocks communication between devices within the network.
Check your TV's firmware version. Manufacturers regularly release updates that add support for new codecs or improve stability. Wi-Fi DirectGo to the settings menu, select the section Help → Status → System Software Update and check for updates. This often resolves PC visibility issues.
⚠️ Note: If your router uses a guest network, devices may not be able to see each other. To set up the connection, use your main home network.
Miracast Method: Mirror Windows Screen to Sony
Technology Miracast (implemented in Windows as "Connect") is the native standard for wireless image transmission. Televisions Sony Bravia Support this protocol out of the box, allowing you to stream your entire desktop or a single browser window without installing additional software. To get started, press the input selection button on the remote control (INPUT) and select the source Screen mirroring or Screen mirroring.
On a Windows 10 or 11 computer, press the key combination Win + KThe system will begin searching for available wireless displays. Your TV should appear on the list. SonyAfter selecting a device, a connection confirmation prompt may appear on the TV screen. This prompt must be accepted using the remote control.
- 📺 Open the input menu on your TV and activate Screen Mirroring mode.
- 💻 On PC, click
Win + Kand select your TV from the list. - ✅ Confirm the connection on the TV screen if prompted.
- ⚙️ In Windows display settings (
Settings → System → Display) select the "Repeat" or "Extend" mode.
It's important to note that image quality and input lag depend on the Wi-Fi module's power and the airwaves' congestion. To view videos in 4K or graphics work, it is preferable to use a wired connection or 5 GHz band, since standard Miracast can compress the stream.
Using DLNA to stream media content
If your goal is not to duplicate your desktop, but to play movies, music or photos stored on your PC's hard drive, the technology DLNA will fit perfectly. It allows the TV Sony View shared folders on your computer as network storage. In Windows, this feature is built into "Streaming Media Settings."
To activate, go to the Control Panel, find "Streaming Media Settings," and enable this feature. The system will prompt you to select devices that are allowed access. Find your TV in the list. Sony and set the status to "Allowed." After this, media files will be accessible through the "Media Selection" app on your TV.
| Characteristic | Miracast | DLNA |
|---|---|---|
| Transmission type | Screen streaming video | Files (photos, videos, audio) |
| Impact on PC | Blocking is possible | Background work |
| Quality | Depends on the signal | Lossless original |
| Control | From a computer | From the TV remote control |
Using third party media servers such as Plex or Jellyfin, can significantly expand DLNA capabilities. These programs automatically download covers and descriptions, and stream content with on-the-fly recoding if the TV doesn't support the file format.
Video & TV SideView app and mobile integration
Sony has developed its own application Video & TV SideView, which serves as a bridge between mobile devices, PCs, and TVs. Although originally designed for smartphones, there are web and desktop versions that allow content management. This is especially relevant for older models. Bravia, where support for modern standards may be limited.
Installing the app on your smartphone (Android or iOS) and pairing it with your TV unlocks the "Cast" feature. You can start a video on your phone and send it to the big screen. For PCs, this functionality is often implemented through the Chrome browser and the built-in Cast feature, if the TV supports it. Chromecast built-in.
☑️ Check before connection
In some regions and on certain models, the application may have a different name or be replaced by integration with Google HomeIf the standard Sony app isn't working, check the app store on your TV—it might need a service update.
⚠️ Please note: App interfaces and feature names may differ depending on the year of TV production and the version of the Android TV operating system.
Troubleshooting connection and visibility issues
Despite the standardization of protocols, users often face a situation where the computer and TV SonyThey "don't see" each other. First, check the network type in Windows. If the network is marked as "Public," the system is hiding the device from detection. Switch the network profile to "Private" in the Wi-Fi settings.
It is also worth paying attention to the router settings. Function UPnP (Universal Plug and Play) must be enabled for DLNA to function correctly and for automatic device detection. Without it, the TV may simply not appear in the list of available media servers.
- 🔄 Restart your router, TV, and computer—this solves 80% of DNS cache problems.
- 🛡️ Check your antivirus settings: they often block incoming connections over the local network.
- 📶 Make sure that the devices are not separated by VLANs or guest zones of the router.
If nothing helps, try resetting your TV's network settings to factory defaults. In the menu Settings → Network & Internet Find the reset option. This will delete saved passwords and configurations, often fixing TCP/IP stack software errors.
Comparison of wired and wireless connections
Despite the convenience Wi-Fi, the limitations of wireless technology cannot be ignored. While the bandwidth is usually sufficient for streaming Full HD or even 4K video via DLNA, latency can be critical for gaming or UI interaction. An HDMI cable or LAN connection provides stability that is difficult to achieve with a network.
However, if laying a cable is not possible, using the Wi-Fi standard 802.11ac (Wi-Fi 5) or ax (Wi-Fi 6) produces excellent results. Modern Sony TVs are equipped with powerful modules capable of transmitting bitrates of up to 100 Mbps and higher, which is sufficient for most tasks.
The choice of method depends on your priorities: maximum quality and the absence of lag require a wire, while comfort and the absence of visual noise require wireless technologies.
Why can't my Sony TV see my computer via Wi-Fi?
Most often, the problem lies in the Windows network profile ("Public" instead of "Private") or blocked ports by the firewall. Also, check if UPnP is enabled in the router and that the devices are on the same subnet.
Can you play PC games on a Sony TV wirelessly?
Technically, this is possible via Miracast or Steam Link, but input lag over Wi-Fi can range from 50 to 200 ms, making shooters or fast-paced arcade games uncomfortable. For casual games, lag isn't a problem.
Does my old Sony TV support wireless?
Almost all Sony Bravia models released after 2012 have built-in Wi-Fi. Older (non-Smart) models require an external set-top box (TV box) or an HDMI cable.
