The process of synchronizing devices is based on standards Miracast And DLNA, which are built into Windows operating systems and platforms Android TV, used in new TV models. You won't need to buy expensive adapters if your equipment supports the 802.11ac standard or later. The main thing is to ensure a stable router signal and correctly configure the network settings for both devices.
In this article, we'll take a detailed look at all available methods for streaming images, from built-in Windows features to specialized software. You'll learn how to avoid lag, improve image quality, and solve common issues users encounter when first setting up wireless mirroring.
Preparation of equipment and network infrastructure
Before you begin setup, make sure your computer and TV are Sony Connected to the same Wi-Fi network. This is critical: if one device is connected to a guest channel or mobile hotspot and the other to the main router, detection will be impossible. Check that the signal frequency meets the requirements for transmitting high-definition video. It is advisable to use the 5 GHz band, as it provides greater throughput.
Please note your PC's operating system version. Wireless display functionality requires Windows 10 or Windows 11. On your TV, make sure the firmware is updated to the latest version, accessible through the menu. Settings → Status → System UpdateOlder versions of software may not support new encryption protocols or codecs.
⚠️ Note: If your router has AP Isolation, the wireless connection between your PC and TV will not work. This option must be disabled in your router settings.
Signal strength also plays a role. If the router is located in an adjacent room behind thick walls, image artifacts or audio desync may occur. Ideally, the distance between the transmitter and receiver should not exceed 10 meters unless there are direct obstacles.
Using the built-in Projection feature in Windows
The easiest and fastest way to display an image from your computer on the screen Sony - use the standard operating system utility. This method implements the technology Miracast, which allows you to broadcast your screen in real time without the lag typical of streaming video. To get started, press the key combination Win + K on your keyboard to open the connection panel.
The system will begin searching for available devices within the network range. On the TV screen Sony You may be prompted to allow the connection; you must confirm this with the remote control. Some models require you to launch the app first. Screen mirroring or select the appropriate signal source in the input menu.
- 📺 Press the "Input" button on the remote control and select "Screen mirroring".
- 💻 On PC, click
Win + Kand wait for the TV name to appear. - 🔗 Select the device from the list and confirm the connection on the TV screen.
- 🖥️ Use it
Win + Pto select the display mode (duplicate or expand).
Once successfully connected, you can select the operating mode. "Duplicate" mode simply copies the image from your monitor to your TV, convenient for viewing photos or videos. "Extend" mode turns your TV into a second monitor, allowing you to drag browser or music player windows onto the larger screen while continuing to work on your computer.
☑️ Check before connection
Setting up DLNA and streaming media files
If your goal is not to mirror your desktop, but to play specific files (movies, music, photos), it is better to use the protocol DLNAIt provides a more stable data transfer and allows you to control playback with your TV remote, reducing the load on your computer's processor. In Windows, this feature is called "Stream" and is configured through the Media Control Center.
To activate, open "Streaming Media Settings" in the Control Panel. Here you'll see a list of devices on the network. Find your TV. Sony and allow it to access the content. After that, in the standard Movies & TV app or any other player with DLNA support (for example, VLC or Kodi) the “Transfer to device” button will appear.
The advantage of this method is that the computer acts only as a server. You can turn off the PC monitor or minimize all windows, and playback on the TV will not be interrupted. The image quality is often higher than with Miracast, as a ready-made video stream is transmitted, not a compressed desktop image.
| Parameter | Miracast (Projection) | DLNA (Streaming) |
|---|---|---|
| Purpose | Full screen broadcast | Playing files |
| Control | From a computer | From a TV or PC remote control |
| Delay | Minimum | None (buffering) |
| CPU load | High (coding) | Low (gear only) |
Why might video lag when using DLNA?
Slowdowns are often caused not by Wi-Fi speed, but by the bitrate of the video file itself. If you're streaming a heavy 4K HDR rip with a high bitrate over a 2.4 GHz network, the channel's bandwidth may not be sufficient for buffering. The solution is to reduce the stream quality in the player settings or switch to 5 GHz.
Using the Sony Video & TV SideView app
For equipment owners Sony the company developed its own application Video & TV SideView, which turns a smartphone or tablet into an advanced remote control and also allows you to stream content from a PC if it's synced with the mobile device. Although the app is designed for mobile platforms, it provides access to additional TV features unavailable with a standard connection.
By installing the app on your computer (via an emulator or if a desktop version is available for your OS) or using a PC-to-smartphone connection, you gain access to an electronic program guide and viewing history. This is especially convenient for scheduling program recordings or searching content across all connected sources at once.
The app's functionality is constantly being updated, adding support for new streaming services and improving smart home integration. If the standard methods seem limited, try linking devices via an account. Sony Entertainment Network, which will allow you to sync bookmarks and preferences.
⚠️ Please note: The app interface and available features may vary depending on the region and year of TV production. In newer models with Google TV SideView functionality can be integrated directly into the system.
Alternative solutions: Chrome and third-party software
If built-in Windows tools are unstable or the TV doesn't detect the computer, a browser can help. Google ChromeIt has a built-in casting feature that often works even when system tools fail. Open your browser, click the three dots in the upper right corner, and select "Cast."
In the menu that opens, you can choose to broadcast a specific tab, the entire desktop, or audio. This method is especially effective for viewing web content, YouTube, or HTML5 presentations. Streaming quality depends on your processor's performance, as the browser handles the encoding of the video stream.
- 🌐 Open the Chrome menu (three dots) and select "Cast."
- 🖥️ Click "Sources" and select "Cast Desktop".
- 📺 Select your TV Sony from the list of devices.
- 🔊 To transmit sound, be sure to check the "Broadcast sound" box.
There are also specialized programs like LetsView or AirServer, which are installed on a PC and emulate AirPlay reception or other protocols. They're useful if you need to connect a MacBook to a Sony TV without purchasing an Apple TV.
Quality solution and optimization
A wireless connection is always susceptible to external interference. If you notice artifacts, blocky images, or audio desync, first check your Wi-Fi channel usage. Neighbors' routers, microwave ovens, and Bluetooth devices can create noise, especially in the 2.4 GHz band.
Try changing the broadcast channel in your router settings to a less congested one (for example, 1, 6, or 11). Updating the wireless adapter drivers on your computer can also help. Manufacturers often release patches that improve the stability of connections with multimedia devices.
If the problem persists, reset the network settings on your TV. In the menu Sony go to Settings → Network → Network Reset and reconnect. This will flush the DNS cache and update the IP address, eliminating addressing conflicts.
Why can't my Sony TV see my computer via Wi-Fi?
Most often, the problem is that the devices are on different subnets or access point isolation is enabled on the router. Also, check whether your antivirus software or Windows Firewall is blocking incoming connections to the wireless display service.
Can you play games on TV via Wi-Fi?
Yes, but for comfortable gaming, you need a Wi-Fi 6 (802.11ax) router and a direct line of sight between your PC and the router. For competitive shooters, it's still better to use a wired HDMI connection due to the inevitable micro-latency of the wireless protocol.
How do I transfer sound from my computer to my TV if the video is playing but there is no sound?
Click the speaker icon in the Windows tray, select the playback device, and click the name of your Sony TV. If it's not listed, right-click in the device selection area and enable "Show disabled devices."
