Miracast technology allows you to broadcast your screen in real time, and DLNA Ideal for streaming existing files, the method you choose depends on your PC's operating system version, TV model, and intended use.
In this article, we'll take a detailed look at all available connection options, from built-in Windows features to specialized apps. You'll learn how to set up a network, which security settings to check, and how to eliminate potential signal lag. Proper setup will ensure a stable, high-quality image without compression artifacts.
Equipment preparation and network infrastructure
Before starting the setup, make sure that all devices are in a single information space. Local area network The setup should be organized so that the computer and TV receive IP addresses from the same router. If you have a complex network with multiple access points or a mesh system, make sure the devices aren't isolated from each other by your ISP's security settings.
The quality of your wireless connection directly impacts the smoothness of your video stream. To transmit images at a resolution Full HD or 4K It is recommended to use a range 5 GHz, which is less congested and provides higher throughput. In the range 2.4 GHz Interference from neighboring networks and household appliances is possible, which will lead to jerky pictures.
⚠️ Note: If your router is distributing a network with the same name (SSID) for both bands, try temporarily separating them or forcing your PC to connect to the 5 GHz network to diagnose speed issues.
Make sure the software is up to date on both devices. On TVs Sony Bravia with the operating system Android TV or older models with their own interface may receive updates regularly. Firmware must be the latest version to ensure compatibility with modern data transfer protocols.
Screencasting via built-in Windows tools (Miracast)
The most universal way is to use technology Miracast, which is built into the Windows 10 and 11 operating systems. This protocol allows for a direct Wi-Fi connection between devices without a router to transmit a video stream, although control is often carried out over a local network. To get started on a TV Sony You need to run the appropriate application.
Press the button on the remote control Input or Home and find the "Miracast" or "Screen Mirroring" app. Once launched, a "waiting for connection" message will appear on the screen. On your computer, go to the notification center or press the keyboard shortcut Win + K.

Using DLNA technology for multimedia
If your goal is to play stored movies, photos or music, and not mirror the entire screen, then the technology DLNA This is the best option. It allows the TV to view the computer as a network storage device and play content using its own media player, offloading the PC's processor. This ensures more stable playback of large files.
In the Windows operating system, you need to set up folder sharing. Open "Settings" from the menu. Start, go to "Network & Internet" and select "Sharing Options." Turn on network discovery and file and printer sharing for the current network profile.
Next, select the folder containing the media files, right-click, and go to Properties. In the "Sharing" tab, click "Advanced" and check "Share with others." You can also use the "Media Streaming" feature in the Control Panel to allow access for the device. Sony.
| Protocol | PC load | Latency | Best use |
|---|---|---|---|
| Miracast | High | Medium/High | Presentations, browser, photos |
| DLNA | Low | Absent | Movies, TV series, music |
| Google Cast | Average | Low | Streaming from a browser |
Once set up, go to the "Media" section on your TV or launch the "Photos," "Music," or "Video" app. Your computer should appear in the list of sources. Navigate using the remote. Sony, which makes the viewing process as comfortable as possible.
Why doesn't the TV see the movie folder?
Often, the problem lies with the file system format or codec. Make sure the video files have the .mp4, .mkv, or .avi extension and use the H.264 codec. Some older Sony models may not support the newer HEVC/H.265 codecs without external decoding. Also, make sure the network type in Windows is set to "Private" and not "Public," as device discovery is disabled by default in the public profile.
Streaming via Google Chrome and Chromecast
Many models Sony Bravia equipped with built-in support Chromecast or work on the basis Android TV, which allows you to use the Google Chrome browser to cast tabs. This method is convenient if you need to display the contents of a specific website, online movie, or cloud document.
Open the Chrome browser on your computer and make sure it's updated to the latest version. Click the three dots in the upper-right corner and select "Cast." In the menu that opens, select a source: "Cast a tab," "Cast the entire screen," or "Cast a file."
Find your TV in the list of available devices. SonyIf your device isn't visible, make sure your browser's discovery feature is enabled. For more functionality, you can install the official extension. Google Cast, which will add a broadcast button to the toolbar.
⚠️ Note: When casting a browser tab, audio may not be transmitted by default. Make sure "Cast Tab" is selected in the casting menu and "Cast Audio" is checked, if necessary.
The advantage of this method is the ability to control playback from a phone or tablet, provided they are connected to the same Google account. However, this method is not suitable for games due to the noticeable delay between keyboard input and display on the screen.
Third-party applications and specialized software
Built-in operating system tools don't always provide perfect stability, especially in challenging network conditions. In such cases, third-party programs designed specifically for content streaming come to the rescue. One of the most popular solutions is the app Sony Video & TV SideView or more modern analogues for Android TV.
For users seeking maximum control, there is a program Let's View or AirServerThey can be installed on both a PC and a TV (if the platform allows it, for example, via an APK on Android TV). These apps often offer more flexible picture and sound quality settings.
Video card owners NVIDIA can use the function NVIDIA GameStream (via the GeForce Experience interface), although support for this feature is gradually being phased out in favor of other solutions. It allows for streaming games and desktop content with minimal latency using the graphics card's hardware encoding.
When using third-party software, it's important to pay attention to your firewall settings. Antivirus software or your system's firewall may block incoming connections from the receiver app on your TV. When you first launch the program, it will ask for network access permission—this must be approved for private networks.
Diagnosing problems and improving connection quality
Even with proper setup, there may be situations where the image flickers or the sound is out of sync. The first step in troubleshooting is always checking the signal strength. Move your laptop closer to the router or, conversely, move the router to a more central position to improve coverage.
Interference from neighboring Wi-Fi networks is a common cause of instability. Use mobile Wi-Fi analysis apps to find the least congested channel. You can manually switch the broadcast channel to a clearer one in your router settings, which often works wonders for streaming stability.
