Modern televisions Sony Equipped with powerful multimedia platforms that make it easy to stream content from external devices, connecting your computer to your TV via Wi-Fi eliminates the need to run long HDMI cables across the room. This solution is ideal for watching high-definition movies, presentations, or playing games on a large screen without losing image quality.
However, the setup process may vary depending on your PC's operating system and TV's software version. Wireless transmission Data synchronization requires a stable signal and proper network configuration. In this article, we'll cover all current synchronization methods in detail, including built-in Windows features and dedicated Sony apps.
Before you begin, make sure both devices—your laptop and TV—are connected to the same Wi-Fi access point. This is critical, as the router acts as a bridge, transmitting the video stream between the devices. If the devices are on different subnets, detection will be impossible, and you'll waste your time.
Preparatory stage: checking equipment and network
Successful synchronization begins long before you click the "Connect" button. The foundation of the entire system is the quality of your local network. If your router operates at 2.4 GHz and is overloaded with neighboring networks, the video stream may be choppy or have low resolution. For 4K video streaming, it is highly recommended to use the 2.4 GHz band. 5 GHz.
It is also worth checking that your TV firmware is up to date. Sony Bravia or models from a different series. Manufacturers regularly release updates that fix data transfer protocol bugs and improve connection stability. Older software may simply not support new encryption standards or codecs used by your operating system.
⚠️ Important: If your router has the "Client Isolation" feature, devices on the network will not be able to see each other. Be sure to disable this option in your router settings before beginning setup.
Make sure your computer has the latest drivers for your Wi-Fi adapter. Video streaming issues often occur because the network card is running in power-saving mode and can't provide the required throughput. Check Device Manager and ensure the adapter supports the required standards. 802.11ac or newer.
Miracast Method: Native Windows Screen Sharing
The easiest way, which does not require installing additional software, is to use technology MiracastIn Windows 10 and 11, this feature is built in by default and is called "Connect" or "Projection." Sony TVs support this standard, often labeling it as "Screen Mirroring."
To get started, press the key combination Win + K on your computer's keyboard. The "Connection" panel will appear on the right, where the system will begin searching for available wireless displays. If your Sony TV is turned on and connected to the network, it should appear in the list within a few seconds.
After selecting a device, a connection confirmation prompt may appear on the TV screen. Use the remote control to grant access. It's important to understand the difference between the two modes: you can duplicate the screen (a copy of the image) or extend the desktop, using the TV as a second monitor. The second option is often more convenient, as it allows you to control the workflow from the main laptop screen.
☑️ Miracast setup checklist
Picture quality in Miracast mode directly depends on the power of your Wi-Fi router and your distance from it. If you notice cursor lag or image artifacts, try moving closer to the router or switching your TV to a wired LAN connection if possible, although the streaming will still be over the air.
Using the Video & TV SideView app
Sony has developed its own application Video & TV SideView, which offers deeper control over content than standard Miracast. It not only allows you to mirror your screen but also control playback of media files stored on your computer's hard drive. This is especially useful if you want to watch movies without taxing your computer's processor with constant video encoding.
For this method to work, you need to download and install the app on your computer from the official Sony website or the Microsoft Store. After installation, launch the program and wait for it to scan your network. Your TV should appear in the list of detected devices.
The main advantage of this method is its support for a wider range of file formats and the ability to control playback with the keyboard and mouse. You can create playlists, add subtitles, and adjust the volume independently of Windows system settings.
What should I do if the app doesn't detect the TV?
If your search yields no results, check your Windows Firewall. It often blocks incoming connections for new applications. Try temporarily disabling your antivirus or adding the application to the exceptions list. Also, make sure your PC's network settings are set to "Private Network" rather than "Public."
It's worth noting that the app's functionality may vary depending on the year of your TV model. On newer Android TV models, some features may be integrated directly into Google's system, making the standalone app less relevant. However, for older Smart TV models, this is the primary tool.
Broadcasting via Google Chrome (Chromecast built-in)
Most modern Sony TVs run on the Android TV operating system, meaning they have built-in support for the technology. ChromecastThis opens up unique opportunities for PC owners using Google Chrome or Microsoft Edge (based on the Chromium engine). You can broadcast not only tabs, but also the entire desktop or even individual files.
To start casting, open the Chrome browser on your computer. Click the three dots in the upper-right corner of the menu and select "Cast." A list of available devices will appear in the window that appears. If you want to cast the entire tab, simply select your Sony TV.
However, if you need to display your desktop or a heavy application, click the "Sources" button in the casting menu and select "Cast Desktop." This will stream any window running on your computer with minimal latency, comparable to a wired connection.
| Parameter | Miracast (Windows) | Chromecast (Chrome) | DLNA (Media) |
|---|---|---|---|
| Transmission type | Real-time screen | Tab or screen | Files (photos, videos) |
| Delay | Average | Low (depending on PC) | Absent |
| Quality | Dynamic | High (up to 4K) | Original file |
| Sound | It is transmitted | It is transmitted | It is transmitted |
A key advantage of Chromecast is its ability to use your computer as a remote control. You can continue working in other tabs or programs while the video plays on your TV. This makes it ideal for watching online movies, which may block screen capture via Miracast due to DRM protection.
Setting up a DLNA server for multimedia
If your goal is not screen mirroring, but viewing photos or video files stored on your hard drive, the best solution is technology DLNAIt allows the TV to view folders containing media files on the computer as network storage. This reduces the load on the processor, as the TV decodes the video itself, receiving the finished data.
In Windows, this feature is called "Media Streaming." To enable it, go to "Settings" -> "Network & Internet" -> "Status." Find the "Sharing options" link and enable network discovery. Then, search for "Media Streaming settings" in the system search bar and enable this feature.
After turning on your Sony TV, a computer icon should appear in the source menu (Input button). Once you open it, you'll see the folder structure. Sony TVs typically have an excellent built-in player that supports most popular formats, including MKV, AVI, and MP4.
⚠️ Please note: TV operating system interfaces and Windows versions are subject to update. Menu item locations may change. If you cannot find the settings described, please consult the official user manual for your specific Sony model and OS version.
For advanced users who find the capabilities of standard DLNA insufficient, it is recommended to install a third-party media server, such as Plex or Universal Media ServerThese programs automatically download movie covers, sort content by genre, and allow you to stream video with on-the-fly recoding if your TV doesn't support the file format.
Solutions to common problems and errors
Despite the simplicity of the technology, users often encounter connection issues. One of the most common is that the TV simply doesn't appear in the list of available devices. In 90% of cases, this is due to the devices being on different networks. Check if you're using a guest Wi-Fi network on one of the devices, as they are often isolated from the main local network.
Another common issue is audio and video desynchronization or constant buffering. This indicates a lack of bandwidth. Try lowering the streaming resolution in Windows settings (for example, from 4K to 1080p) or closing other bandwidth-consuming programs, such as torrents or Steam downloads.
If you see a picture but no sound, check your default playback device in Windows. Click the speaker icon in the system tray, select the arrow next to the volume slider, and make sure your Sony TV is selected, not your laptop speakers. Sometimes audio drivers need to be updated separately from video drivers.
If all else fails, perform a full reset of your TV's network settings. This is usually found in the "Network Settings" section of the Sony menu. Settings → Network → Reset network settingsThis will remove all saved passwords and configurations, often clearing up software conflicts that have accumulated over time.
Comparison of wired and wireless connections
Although this article focuses on Wi-Fi, it's impossible not to mention the alternative. Wireless connections offer convenience and freedom from wires, but they always introduce input lag. While this isn't noticeable when watching movies or browsing photo albums, a 50-100ms delay can be critical for fast-paced shooters or competitive gaming.
A wired HDMI connection ensures instant signal transfer and maximum bandwidth, allowing for uncompressed HDR content and high-resolution audio. If you plan to use your TV as your primary monitor for work or gaming, a cable remains the undisputed leader in terms of quality.
However, technology doesn't stand still. The Wi-Fi 6 standard, supported by new Sony TVs and modern routers, significantly reduces latency. For office presentations, watching YouTube, or surfing the web, the difference between cable and high-end Wi-Fi becomes virtually imperceptible to the human eye.
Why can't my Sony TV see my computer via Wi-Fi?
Most often, the problem lies in Windows sharing settings. Make sure "General Discovery" and "File and Printer Sharing" are enabled in the Network and Sharing Center. Also, check if your antivirus software is blocking network connections.
Can you play games on TV via Wi-Fi?
Yes, but with some caveats. For casual strategy or card games, latency isn't a concern. For shooters and racing games, a wired HDMI connection is recommended, as even a small amount of latency in a wireless signal can degrade the gaming experience.
How to improve picture quality during wireless broadcasting?
Use a router that supports 5 GHz, place your computer and router closer together, close background programs that consume bandwidth, and select "Second screen only" in the projection settings to reduce the load on your graphics card.
Do older Sony TVs support Wi-Fi Direct?
Most Smart TV models released after 2013 support Wi-Fi Direct or Miracast. For precise information, check your model's specifications on the official website by entering the serial number.
