Modern Sony Bravia TVs, powered by the Android TV operating system, offer a wide range of multimedia options. One of the most convenient scenarios is wirelessly connecting a computer or laptop to view content on the big screen. This eliminates the need to run long HDMI cables across the room and allows you to instantly share photos, videos, or presentations.
There are several ways to establish a connection between devices, and the choice depends on your goals: whether you simply want to stream media files or mirror your entire desktop. In this article, we'll cover all the current options in detail, from built-in Windows features to third-party software. Wireless data transmission has become a quality standard, but requires proper configuration of both devices.
Before setting up, make sure your Sony Bravia TV and computer are connected to the same Wi-Fi network. This is a fundamental requirement for most data transfer protocols, such as DLNA and Miracast. If your router supports dual-band (2.4 and 5 GHz), it's recommended to use the 5 GHz frequency for more stable high-definition video transmission.
Preparing equipment and network
Successful synchronization of gadgets begins with properly preparing your network environment. Make sure your Sony Bravia TV has the latest software version installed, as updates often fix communication protocol bugs. Go to the menu Settings → System → About → Software Update and check for new versions.
The computer also needs to be visible on the local network. In Windows, this is controlled through the sharing settings. If your PC is running macOS, the process will differ because it uses AirPlay technology, which is also supported by many Sony models.
⚠️ Note: Antivirus programs or firewalls on your computer may be blocking incoming connections from the TV. If the devices are unable to see each other, try temporarily disabling the firewall to test.
For stable 4K streaming, your screen resolution and bandwidth must meet the requirements. A weak Wi-Fi signal can cause audio and video to become out of sync or artifacts to appear.
Screencasting via Miracast (Wi-Fi Direct)
The fastest way to display content from your computer to a Sony TV without a router is Wi-Fi Direct, known in Windows as Miracast. It creates a direct connection between devices, minimizing latency. On Sony TVs, this feature is often called "Casting" or "Screen Mirroring."
To activate, press the diamond button on the remote control or select the option in the signal source menu. Screen MirroringAfter this, the TV will go into connection standby mode. On a computer running Windows 10 or 11, press the key combination Win + K to open the "Connection" panel.
The name of your Sony Bravia TV should appear in the list of available devices. Once selected, the pairing process will begin, and your desktop image will appear on the big screen. This method is ideal for showing presentations or browsing the web.
- 📺 High quality image transmission without compression.
- 🎮 Minimal latency, suitable for some games.
- 🔌 Does not require an active internet connection, only a working Wi-Fi module.
☑️ Check before connecting Miracast
It's worth noting that when using Miracast, your laptop's battery may drain faster because the wireless adapter operates in high-power mode. You may also experience a slight reduction in TV brightness depending on your power saving settings.
Using Chromecast Built-in
Sony Bravia Android TVs have built-in Google Chromecast support. This allows you to stream content from Google Chrome browser tabs or your entire desktop directly to your TV. This method is convenient because it's controlled from your computer, while the TV handles video decoding.
To get started, open the Google Chrome browser on your computer. Click the three dots in the upper-right corner of the menu and select Broadcast... (Cast). In the window that opens, you'll see a list of available devices. If you only want to show one tab, select it in the source.
If you need to duplicate the entire screen, select in the source menu Broadcast your desktopThis will display all windows open on your PC, including File Explorer and other programs. Image quality in this mode depends on the power of your router.
Why might Chromecast not work?
This feature may not work if your antivirus software blocks the local port or if your computer and TV are on different subnets (for example, if guest Wi-Fi is enabled). Also, make sure your browser doesn't have any ad-blocking extensions installed at the network level, as they can interrupt the handshake connection.
The advantage of this method is that you can use your computer for other tasks without interrupting the stream if you're streaming a specific tab. However, this method isn't suitable for gaming due to noticeable input lag.
Setting up a DLNA server for media files
If you want to view movies, photos, or listen to music stored on your computer's hard drive, DLNA technology is your best bet. It allows your Sony TV to view your computer's folders as external network drives and play content using its own media player.
In Windows 10 and 11, the feature is called "Media Streaming." You can find it in Control Panel or Network Settings. You need to enable streaming and add your Sony TV to the list of allowed devices. After that, the "Servers" option or the name of your PC will appear in the TV's input source menu.
File navigation is done using the TV remote control. The interface may not be as user-friendly as on a computer, but playback quality will be excellent, as the TV decodes the stream itself.
| Parameter | Description | Recommendation |
|---|---|---|
| Video format | Supported codecs | MP4, MKV, AVI |
| Audio track | Audio compression type | AC3, AAC, PCM |
| Subtitles | Text format | SRT, ASS (external) |
| Permission | Maximum quality | Up to 4K UHD |
⚠️ Note: Operating system interfaces and TV menus are subject to update. The location of the "Media Streaming" menu items in Windows or "Servers" in Android TV may differ depending on the firmware version.
For advanced users, it is recommended to use specialized software, for example, Universal Media Server or PlexThese programs offer more flexible transcoding settings and a beautiful interface with movie covers.
Connecting via AirPlay for macOS
Apple MacBook owners are in luck, as many modern Sony Bravia TV models natively support the AirPlay 2 protocol. This allows you to mirror your screen or individual windows without installing additional apps. Check for the AirPlay icon in your TV's quick settings menu.
On your Mac, click the Control Center icon in the menu bar and select "Screen Mirroring." Find your Sony TV in the list of devices. To confirm the connection, a four-digit code may appear on the TV screen. Enter it on your computer.
AirPlay on Sony Bravia not only mirrors your screen but also outputs audio to your TV's external speakers, making it convenient for watching videos wirelessly. It also supports photo sharing directly from your gallery.
- 🍏 Full integration with the Apple ecosystem.
- 🎵 Simultaneous transmission of high-quality audio and video.
- 🔄 Ability to switch audio sources on the fly.
It's important to enable AirPlay support on your TV in the network settings. This is usually enabled by default, but on corporate networks or in guest mode, it may be disabled by the administrator.
Solution and troubleshooting
Despite the ease of setup, users may encounter issues. The most common is that the computer doesn't see the TV in the list of available devices. In this case, first check to see if the Wi-Fi network is isolated. Some routers have an "AP Isolation" feature that prevents devices within the network from exchanging data.
Another common issue is low frame rates or choppy images. This indicates a congested wireless channel. Try lowering the broadcast resolution in Windows projection settings or switching your router to a less congested channel.
If the sound plays on your computer instead of your TV, you'll need to manually change the audio output device. In Windows, this can be done by clicking the speaker icon in the system tray and selecting your Sony TV from the list.
⚠️ Note: Updating your graphics card drivers may reset projection settings. Always check your zoom settings if the image appears to be outside the TV's screen.
In some cases, rebooting your network equipment can help. Turn off your router, TV, and computer for 30 seconds, then turn them back on in this order: router → TV → computer. This will flush the DNS cache and update the IP addresses.
