Wireless connection between the computer and the brand's TV Sony Provides access to movies, photos, and games in high definition. This solution is ideal for setting up a home theater or hosting presentations.
The synchronization process may seem complicated at first glance, but in practice it only takes a few minutes. You don't need to be a networking expert to set it up. local networkIn this article, we'll cover all available methods, from built-in Windows functions to specialized applications.
The main difficulty often lies not in the connection process itself, but in choosing the right data transfer protocol. Sony Android TV and older models with proprietary systems may require different approaches. We'll look at universal methods that work on most current models.
Preparing equipment and network
Before you begin setup, make sure that both devices - your computer and Sony TV — connected to the same wireless network. This is a critical requirement for device detection. If your router operates in two bands (2.4 GHz and 5 GHz), it's best to have both devices on the same band, although modern routers often combine them into a single network.
Check that your TV's firmware is up to date. Outdated firmware may contain bugs that prevent the feature from working. Miracast or DLNA. To check for updates, go to the settings menu of your Sony Bravia or another model.
⚠️ Note: If your router is configured with AP Isolation, devices will not see each other even on the same network. This feature is often enabled on guest networks in hotels or hostels.
- 📶 Make sure the Wi-Fi signal is stable and the reception level is sufficient in the area where the TV is located.
- 💻 Your computer must be running Windows 10 or 11 for native wireless display support.
- 🔌 The TV must be turned on and in standby mode to receive a signal, and not in deep sleep.
After completing these simple steps, you can move on to choosing a connection method. There are several main technologies, each with its own advantages for different use cases.
Using the Projection feature in Windows
The fastest way to get your entire desktop to appear on your TV is to use a built-in Windows feature called ProjectionThis technology is based on the Miracast standard, which is supported by most modern TVs. Sony with Smart TV function.
To get started, press the key combination Win + K on your computer's keyboard. The system will begin searching for available wireless displays within range. If the TV is turned on and connected to the network, its name will appear in the list on the right.
After selecting your TV, you may be prompted to confirm the connection on your PC screen. On some models Sony Android TV You will need to accept the connection through the pop-up window on your TV screen using your remote control.
☑️ Check before connection
It's important to note that this method may cause a slight image lag. This is normal for watching videos or presentations, but can be disruptive during fast-paced games. Delay depends on the speed of your router and the load on the wireless channel.
Setting up DLNA for media streaming
If your goal is not to broadcast the entire screen, but just to run a video file or show photos stored on your hard drive, it is better to use the technology DLNAThis protocol allows the TV to act as a renderer, playing content directly from the computer, reducing the load on the system.
In Windows, open "Streaming Media Settings." You can do this through the Control Panel or search. In the window that opens, find your TV. Sony in the list of devices and allow it to access your media library.
After setting up access, open the video or photo folder on your computer, right-click the file, and select "Cast to device." Select your TV from the list. Playback will begin automatically.
| Parameter | Projection (Miracast) | DLNA | Chrome Cast |
|---|---|---|---|
| Content type | Full PC screen | Videos, photos, music | Browser tabs, streams |
| Delay | Medium/High | Absent | Low |
| CPU load | High | Low | Average |
| Quality | Depends on the signal | Original file | Adaptive |
The advantage of DLNA is that the TV decodes the video stream itself. This means you can minimize the window on your computer or even turn off the monitor, and playback will continue on your TV. Sony TV will continue without interruptions.
Video & TV SideView app
Company Sony developed my own application Video & TV SideView, which turns a smartphone, tablet, or computer into a powerful remote control and media server. Although it was originally created for mobile platforms, there are emulators and web versions that allow you to use its functionality on a PC.
The app's main feature is the ability to cast content from the internet directly to your TV. You can find a video in your computer's browser and send it to the big screen, eliminating the need to download the file.
To use the app, you need to register your device in the app. On your TV, find "Apps" in the app menu. SideView and launch it. On your computer, enter the registration code displayed on the screen. Once paired, the devices will be visible to each other on the local network.
⚠️ Note: App functionality may vary depending on your region and TV model year. Newer models from 2026-2026 may have some features integrated directly into Google Home.
Using proprietary software often provides a more stable connection than standard Windows tools, especially if the router has specific security settings.
What should I do if the app doesn't detect the TV?
Make sure Windows Firewall isn't blocking the SideView app. Try temporarily disabling your antivirus software to test. Also, make sure "Control by smartphone apps" or a similar option is enabled in your TV's network settings.
Broadcasting via Google Chrome
Browser Google Chrome has a built-in broadcast function that works on almost all TVs Sony With Chromecast built-in or Android TV support, this is one of the most convenient ways to share the contents of a browser tab or your entire desktop.
Open the Chrome browser on your computer. Click the three dots in the upper-right corner of the menu and select "Cast." In the window that appears, select "Sources" and select what you want to cast: a tab, the entire screen, or a file.

- 🖥️ Allows you to display presentations and documents in high quality.
- 🔊 The sound is also transmitted to the TV, switching from the laptop speakers.
It's worth noting that broadcasting the entire screen increases the load on the computer's processor, as it must encode the video stream in real time. This isn't a significant issue for static images, but 4K video may require a powerful PC.
Troubleshooting and troubleshooting
Even with proper setup, situations may arise where the computer doesn't see the TV or the connection constantly drops. Most often, the problem lies with network security settings or drivers.
If the devices can't find each other, try rebooting the router. Sometimes the DHCP server cache becomes full, preventing new connections from establishing correctly. It's also worth checking if your router has a speed limit for wireless clients.
If you experience image quality issues (jerking, artifacts), try lowering the resolution of the screen being streamed. For Full HD TVs, streaming a 4K signal from a computer isn't always necessary; this only puts unnecessary strain on the Wi-Fi channel.
⚠️ Note: Antivirus programs (Kaspersky, ESET, Avast) often have their own firewall, which can block discovery protocols. Add your home network to the list of trusted networks.
If nothing helps, reset your TV's network settings to factory settings. In the menu Sony This is usually located in the section Settings → System → About → ResetThis will reset the network settings to their original state, eliminating any possible software conflicts.
Why isn't my Sony TV showing up in the Wireless Displays list?
The most common problem is that the discovery feature on the TV itself is disabled. Go to the TV's network settings and look for the "Screen Mirroring" or "New Connections" option. This option needs to be enabled for the TV to broadcast a signal indicating it's ready to connect.
Is it possible to connect a computer to an old Sony TV without Smart TV?
Directly via Wi-Fi – no, as the TV lacks a Wi-Fi module or operating system. You'll need an external set-top box (Android Box, Apple TV, Chromecast) or a DLNA server if the TV has a built-in media player with network support (via LAN or Wi-Fi adapter).
How to improve picture quality over a wireless connection?
Use the 5 GHz band if your router and TV support it. It's less noisy and provides better throughput. Also, try to minimize the distance between the router and TV, avoiding signal penetration through thick concrete walls.
Does the TV take internet from the computer when connected?
No, when using Miracast or DLNA, your computer doesn't share your internet connection with your TV. The TV uses its own connection to the Wi-Fi router to access online services, while the PC only streams media content. If you need to share your internet connection, use the "Mobile Hotspot" mode in Windows.
