Stream movies from your computer to your Sony TV via Wi-Fi

Modern Sony TVs running Android TV or Google TV are powerful multimedia centers, but their built-in features are sometimes limited compared to those of a personal computer. Users often need to play a video file that isn't supported by the built-in player or access content from a local network without redownloading it. In this case, a wireless connection is the most elegant solution, eliminating the need for long HDMI cables or transferring files to a USB drive.

There are several proven streaming methods, each with its own unique characteristics in terms of image quality, latency, and supported formats. DLNA It is ideal for playing already downloaded movies, while the technology Miracast allows you to mirror the entire screen. Understanding the differences between these protocols will help you choose the best method for your specific situation and TV model. Bravia.

In this article, we'll cover every setup step in detail, from checking network settings to using specialized software. You'll learn how to avoid audio and video desync and how to set up high-definition video streaming without loss of quality. Whether you're using Windows 10, Windows 11, or macOS, there's a working method for integrating your PC into your Sony home ecosystem.

Preliminary preparation of equipment and network

A high-quality wireless network is the foundation for stable video streaming. Before configuring software components, you need to ensure that your router can deliver sufficient bandwidth. To stream video in HD resolution 4K or Full HD High bitrates require a stable connection, which is often impossible to provide in congested frequency bands.

Both devices—the computer and the TV—must be connected to the same local network. This means they must be connected to the same router, not to different access points within a single network, unless you have proper roaming configured. If your router supports dual-band operation, it's highly recommended to use the same band. 5 GHz, as it is less susceptible to interference from household appliances and neighboring networks.

⚠️ Attention: Make sure "AP Isolation" is disabled on your router. If this feature is enabled, devices on the Wi-Fi network will not be able to see each other, and streaming will be impossible, even if there is an internet connection.

Also check the software version of your Sony TV. Manufacturers regularly release updates that may contain fixes for wireless data protocols. Go to the menu Settings → System → About TV → System software updateto make sure the firmware is up to date.

DLNA method: playing local files

Technology DLNA (Digital Living Network Alliance) is the de facto standard for streaming multimedia content within a home network. It allows a computer to act as a server, and a Sony TV to act as a renderer, receiving and playing the stream. The main advantage of this method is that playback is controlled using the TV remote, while the computer can be used for other tasks.

Windows 10 and 11 come with a built-in media server, but it requires proper folder access settings. You don't need to install third-party software if your video files are located in standard directories. However, for more flexible codec and subtitle management, many users prefer specialized programs.

Let's look at a comparison of built-in Windows tools and popular third-party solutions for setting up a DLNA server:

Parameter	Built-in Windows media server	Plex / Universal Media Server	Kodi
Difficulty of setup	Low	Average	High
Subtitle support	Basic	Extended	Full
Transcoding on the fly	No	Eat	Eat
TV interface	Standard	Beautiful (Plex)	Yours (Kodi)

If you choose third-party solutions such as PlexIt's worth noting that these apps require installing a server on your PC and a client app on your Sony TV (via the Google Play Store). This offers a huge advantage in terms of automatic downloading of cover art, movie descriptions, and library sorting, turning your archive into a personal cinema.

What to do if the TV doesn’t see the computer?

Make sure your Windows network profile is set to "Private" and not "Public." Windows blocks device discovery on public networks for security reasons. Also, check your firewall—it may be blocking incoming connections to the media server.

Screen sharing via Miracast and Wi-Fi Direct

Unlike DLNA, which only transfers files, the technology Miracast And Wi-Fi Direct Allows you to stream the entire desktop or a single browser window. This is ideal for watching online movies that block audio output via DLNA, or for sharing presentations and photos directly from the monitor.

In Windows 10 and 11, this feature is implemented through the Connections panel. Sony TVs usually support this feature natively, but sometimes it needs to be activated in the settings. On older models Bravia This may be called "Screen mirroring," and on newer Android TVs, the feature is built into the device detection system.

To start a broadcast, follow these steps:

• 💻 Press the key combination Win + K on your computer keyboard to open the projection menu.
• 📺 Turn on your Sony TV and make sure it is in connection standby mode (often just being in the Smart TV menu is enough).
• 🔍 Select your TV from the list of available wireless displays in the Windows window.
• ✅ Accept the connection request that appears on the TV screen using your remote control.

It's worth noting that this method places a strain on the computer's graphics card, as it must encode the video stream in real time. This can lead to increased power consumption and system heating. Furthermore, there may be a slight delay between mouse input and display on the TV screen, making this method unsuitable for fast-paced games, but perfectly suitable for movies.

Using Google Chrome for Casting

Since modern Sony TVs are based on Android TV or Google TV, they have built-in support for the technology. Google CastThis opens up another convenient streaming option, especially if you watch movies through web browsers or use streaming services that don't have native DLNA support.

The Google Chrome browser on your computer allows you to stream not only individual tabs but your entire desktop. This method is advantageous because it doesn't require complex network share or server setup. All you need is Chrome installed and a Google account (although you can often do without one if the devices are on the same network).

Here's how it works: open the Chrome browser, click the three dots in the upper-right corner, and select "Cast." In the menu that opens, you can choose what to cast: a tab, a file, or the entire screen. If you select "File," you can specify the path to the video on your hard drive, and the browser will begin streaming it to your TV.

⚠️ Attention: When casting a browser tab, audio may not be transmitted by default. Be sure to check "Cast audio" in the source selection menu if you're watching a movie and not just displaying images.

The advantage of this method is its versatility: it works equally well on Windows, macOS, and Linux. However, image quality may be limited by browser capabilities and the processor power required to encode the video stream on the fly. For older or weaker laptops, this can be a bottleneck.

Setup for macOS and Apple TV users

For computer owners MacBook or iMac Were a little less fortunate in terms of native integration with Android TV, as Apple's ecosystem is tailored to its own protocol. AirPlayHowever, many modern Sony TVs support AirPlay 2 out of the box, allowing you to stream content without installing additional software on your computer.

If your Sony TV model doesn't natively support AirPlay 2 (usually models released before 2019), you'll need to install a receiver app from the Google Play Store on your TV. Popular options include: AirScreen or Receiver for AirPlayAfter installing this application, the TV becomes visible to the macOS system as an audio and video output device.

To enable streaming on Mac:

1. Make sure your Mac and TV are connected to the same Wi-Fi network.
2. Click on the Control Center icon in the menu bar (two toggle switches).
3. Select Screen Mirroring and find your Sony TV in the list.
4. Enter the code that appears on the TV screen if confirmation is required.

Also, for Mac users, a great solution is to install a media server, for example, Elmedia Player or using the same Plex, which has excellent compatibility with macOS. This will allow you to stream files locally via DLNA, bypassing the limitations of the AirPlay protocol if it's unstable.

Quality solution and optimization

Even with proper setup, users may encounter issues: video stutters, there's no sound, or the device constantly disconnects. Most often, this is due to an unstable Wi-Fi signal. If the router is located far from the TV, the signal may weaken, which is critical for streaming high-definition video.

Try changing the Wi-Fi channel in your router settings to a less busy one. Disabling other devices that actively consume bandwidth (such as torrents or game downloads) while watching a movie also helps. If the problem persists, check the video file format: some Sony TVs may not support certain audio codecs (e.g., DTS or AC3) when streaming, even if the video is playing.

In such cases, transcoding comes to the rescue. Server programs like Plex or Universal Media Server can re-encode the audio track on the fly into a compatible format (for example, AAC or PCM) so that the TV can play it. This requires sufficient computer processor power.

• 📉 Buffering: If the video constantly pauses to load, reduce the stream quality in the player or server settings.
• 🔊 No sound: Install the codec pack K-Lite Codec Pack on PC or use the player VLC with the rendering function enabled.
• 📶 Connection breaks: Move closer to the router or use a Wi-Fi repeater to strengthen the signal in the TV area.

⚠️ Attention: Sony TV menu interfaces may vary depending on the Android TV operating system version and regional firmware. If you don't find the setting you're looking for, search within the TV settings menu by entering a keyword (e.g., "DLNA" or "Cast").

Frequently Asked Questions (FAQ)

Why doesn't my Sony TV see my computer on the network even though Wi-Fi is working?

The problem is most likely with your Windows network profile. Go to "Settings" → "Network & Internet" → "Status." Click on your connection properties and make sure the "Private" profile is selected. In the "Public" profile, Windows hides your computer from other devices for security reasons.

Is it possible to watch movies from a computer on a TV without a router?

Yes, this is possible using Wi-Fi Direct technology. This connects the computer and TV directly, bypassing the router. However, the transfer speed may be lower, and internet control on the TV will be unavailable. Also, some PC models require a special adapter to operate in access point mode.

The TV plays video, but there is no sound. What's wrong?

A common cause is the TV's lack of support for the audio codec used in the file (often with the DTS format). Solution: Use a computer player (such as VLC) that can transcode audio on the fly, or install a third-party player (such as VLC for Android) on your TV that has built-in codecs.

Does watching movies over Wi-Fi affect the internet speed of other devices?

If a movie is streamed from a local network (from a computer's hard drive), the internet isn't used at all; traffic flows only within your home network. If you're streaming online video (via a browser or torrent streaming), the internet bandwidth is overloaded, and speeds for other devices may drop.
