Modern users rarely limit their content viewing to the small screen of a laptop, preferring to display images on a larger display. Sony BraviaWireless WiFi connectivity eliminates the need for unnecessary cables, making your desktop or media available to the whole family in the living room. Miracast and Sony's built-in protocols allow you to establish communication in minutes if you know the correct sequence of actions.
The setup process may vary depending on your computer's operating system version and TV model. Some older models may require external adapters, while newer ones may require Android TV support native streaming. In this article, we'll cover all the current methods, eliminating the need to purchase expensive equipment.
Before you begin, make sure both devices are on the same local network. Connection stability Directly impacts image quality and the absence of lag when controlling the cursor. Ignoring this basic rule often results in signal interruptions and a deterioration in image quality.
Preparing equipment and checking the network
The foundation of a successful wireless connection is proper local network configuration. Your laptop and TV Sony must be connected to the same router. If you are using a dual-band router, it is advisable for both devices to operate on the same frequency. 5 GHz, as it provides higher bandwidth for the video stream.
Check if the WiFi function is enabled on the TV itself. In the menu Sony Bravia This usually shows up as an active network connection. If the TV is connected via a LAN cable but the laptop is connected via WiFi, streaming is still possible, provided the router correctly handles multicast traffic between wired and wireless clients.
⚠️ Note: If your router has the "Client Isolation" feature, devices will not see each other. This option must be disabled in the router settings.
You can use built-in Windows tools or third-party tools to diagnose signal quality. A weak signal on a laptop will cause artifacts on the TV screen. Make sure the drivers WiFi adapter updated to the latest version, as older versions may not work correctly with media device discovery protocols.
Miracast Method: Native Windows Screen Casting
The simplest and most common method that does not require installing additional software is to use technology MiracastIn Windows 10 and 11, this feature is deeply embedded into the system and can be activated through the Action Center. TVs Sony Bravia Smart TVs often have a built-in Miracast receiver, which may be called "Screen Mirroring" or "Screen Mirroring."
To start the process, press a key combination on your laptop keyboard Win + KThe system will begin searching for available wireless displays.

INPUTon the Sony remote control and select the "Screen Mirroring" or "Screen Mirroring" source. - 🖥️ On PC, go to
Settings → System → Project to this PCand make sure the feature is available. - 🔗 Select your model from the list of available devices Sony Bravia.
Transmission quality depends on the WiFi channel load. If you experience cursor lag, try lowering your laptop's screen resolution before connecting. Hardware acceleration in the graphics driver also plays a role: make sure it is enabled for optimal video stream encoding performance.
☑️ Check before connecting Miracast
Using Chromecast technology through the Google Chrome browser
If the native Windows method doesn't work or is unstable, using a browser is a great solution. Google ChromeMost modern Sony TVs run on Android TV, which means built-in support for the protocol. ChromecastThis method is ideal for displaying browser tabs or videos from websites.
Open the Chrome browser on your laptop, click the three dots in the upper-right corner, and select "Cast." The browser will scan the network and find your TV. You can cast a specific tab or your entire desktop. This method is often more stable than Miracast, thanks to Google's optimizations.
| Parameter | Miracast (Windows) | Chromecast (Chrome) |
|---|---|---|
| Latency | Low (good for gaming) | Average (depending on network) |
| Picture quality | Depends on WiFi drivers | High (adaptive) |
| Sound | Transmitted automatically | Requires tab configuration |
| Compatibility | Windows, Android | All operating systems with Chrome browser |
It's important to note that when casting a tab, audio may not be transmitted by default. To enable audio, click the "Sources" icon in the casting menu and select "Cast Tab," then check the "Cast Audio" box. This is critical for watching movies or listening to music.
Why might Chromecast not be visible to the TV?
If the devices are on different subnets or isolation mode is enabled, the search will return no results. An antivirus firewall on the laptop that blocks local connections may also solve the problem.
DLNA Protocol: View your media library without screen mirroring
When you don't need to see the desktop, but just want to run a video file or photos stored on your laptop's hard drive, the protocol DLNA is the most efficient solution. Unlike mirroring, the TV decodes the stream itself, offloading the laptop's processor and saving battery life.
In Windows, this feature is called "Media Streaming." To enable it, open "Media Streaming Settings" in Control Panel and allow access for your TV. Sony BraviaAfter this, you can launch the content in the standard "Movies & TV" app or through the file's context menu (Right-click → "Cast to device").
The advantage of DLNA is its support for subtitles and the ability to control playback with your TV remote. You can pause, rewind, or change the volume without leaving your couch. However, the file format must be supported by your TV; older codecs may not be supported.
⚠️ Note: The "Streaming Media" menu interface may vary across different Windows builds. If you can't find the item you're looking for, try searching in your system settings.
For advanced users, it is recommended to use media servers such as Plex or Universal Media ServerThey automatically convert videos on the fly if the file format is incompatible with TV, and provide beautiful movie covers and descriptions.
Third-party apps for extended functionality
Sometimes built-in tools aren't enough, especially when you need to stream audio separately or control the cursor with increased precision. In such cases, specialized applications come to the rescue. One of the most popular is LetsView or AirServer, which create a virtual receiver on a PC or improve the quality of transmission on TV.
Some apps allow you to use your TV screen as a second monitor, extending your desktop rather than simply duplicating it. This increases productivity when working with documents or presentations. Installing such software requires installing the client on both your computer and (sometimes) your TV through an app store. Google Play.
- 📡 LetsView: Free cross-platform solution with good image quality.
- 🎮 Steam Link: Ideal for running PC games on your Sony TV with minimal lag.
- 🖥️ TeamViewer: Allows you not only to see the screen, but also to control the computer via TV (requires a remote control and mouse).
When using third-party software, pay attention to access rights. The application may require access to the local network and microphone (for voice control). Always download programs from the developer's official websites to avoid malicious code.
Troubleshooting and error diagnostics
Even with proper setup, situations may arise where the laptop doesn't detect the TV or the connection constantly drops. First, try rebooting the router. This simple step clears the DHCP cache and eliminates IP address conflicts, which often prevent devices from being discovered on the network.
If the issue persists, check your Windows Firewall. It may be blocking incoming connections for the discovery service. Temporarily disable the firewall to test; if a connection is established, create a protocol exception. DLNA And MiracastIt's also worth checking whether your WiFi network is set to "Public" by switching the profile to "Private."
If you see a picture but no sound, check your Windows playback settings. Click the speaker icon in the system tray, select the output device, and find your TV in the list. SonySometimes the system continues to output sound through the laptop's built-in speakers by default.
⚠️ Please note: Antivirus packages (Kaspersky, ESET, Norton) have their own built-in firewalls that can block the local network even when the standard Windows firewall is disabled.
For Sony models with the Android TV operating system, it is useful to clear the cache of the "Screen Mirroring" or "Cast" app. Go to Settings → Applications → System applications, find the relevant service, and select "Clear Cache." This clears temporary connection errors.
