Wirelessly connect your laptop to your TV Sony Bravia Wi-Fi opens up a ton of possibilities: from watching movies on a big screen to presenting without the hassle of wires. However, many users encounter problems—not all TVs Sony support Miracast by default, and standard functions Windows 10 don't always work correctly with DLNA or Google CastIn this article, we'll cover all current connection methods, including hidden settings and workarounds for older models.

Feature of TVs Sony - own ecosystem Bravia Sync and limited support for third-party protocols. For example, even if your Sony KD-55X85J equipped with Wi-Fi, this does not guarantee operation with Miracast without additional devices. We tested all methods on 2018–2023 models and identified key nuances that the manufacturer does not advertise. If you tried to connect via Win + P and received the error "The device does not support Miracast", here you will find the solution.

Important: Sony TVs from 2020 and later (X90J, A80J series and above) only support Miracast via Sony's proprietary software, not the standard Windows protocol.This means that wireless screen sharing may require installing additional apps. Below, we'll explain how to bypass this limitation.

1. Checking the compatibility of your Sony TV and laptop

Before attempting to connect, please ensure your devices support the selected protocol. TVs Sony work with three main wireless broadcast technologies:

• 📶 Miracast — direct screen streaming without a router (requires support on both devices). Works on Sony X950G and newer, but often disabled by default.
• 📡 DLNA — transfer media files (photos, videos, music) via your home network. Supported by all Smart TVs. Sony since 2015.
• 🔗 Google Cast (Chromecast) — broadcasting via apps (YouTube, Netflix). Available on models with Android TV (2016 and newer).

To check support Miracast on the laptop:

1. Click Win + R, enter dxdiag and press Enter.
2. In the window DirectX Diagnostic Tool go to the tab Screen.
3. Find the line Miracast: if specified Available with HDCP support, your laptop is ready to broadcast.

⚠️ Attention: Televisions Sony series W800C, W750C (2015–2016) do not officially support Miracast, but can be enabled via a firmware update. Check the firmware version in the menu. Settings → About.

2. Connect via Miracast (direct screen broadcast)

This is the most universal method, but it does not work on all TVs. SonyIf your model supports Miracast, follow these steps:

On TV:

1. Turn on Wi-Fi: Settings → Network → Network settings → Wi-Fi.
2. Activate Miracast receiving mode:
   • Press on the remote control INPUT → Screen mirroring.
   • On models with Android TV: Settings → Devices → Screen & Sound → Screen Mirroring.

On a laptop (Windows 10):

1. Open Notification Center (icon in the lower right corner).
2. Select Connect (or Project).
3. In the list of available devices, find the name of your TV (for example, BRAVIA-XXXXX).
4. Confirm the connection on your TV (you may be asked to enter a PIN code).

⚠️ Attention: If your laptop does not see the TV, check:

• Are VPNs and firewalls disabled (they may block multicast traffic).
• Is the TV firmware updated (on 2018–2019 models, Miracast often doesn’t work without an update).
• Are both devices connected to the same Wi-Fi network (even for Miracast, some models Sony require a common network).

Disable VPN | Update Wi-Fi adapter drivers | Restart the router | Check Miracast support in dxdiag-->

If the standard method doesn't work, try the alternative method via the app Sony Screen Mirroring (available in Microsoft Store). It bypasses Windows limitations and works even on TVs where Miracast is disabled by the manufacturer.

3. Connecting via DLNA (media streaming)

DLNA It doesn't broadcast the entire screen, but it does allow you to play movies, music, and photos from your laptop on your TV. This method works on all Smart TV Sony since 2015.

On a Sony TV:

1. Open the app Media Player or Video.
2. Select source: Home Network → [Your Laptop Name].
3. Find the file you need and start playback.

DLNA limitations:

• ❌ Does not transmit sound from the browser or games.
• ❌ Does not support subtitles in separate files (only embedded ones).
• ⚠️ May lag when playing 4K HDR (we recommend converting to 1080p).

4. Connecting via Google Cast (Chromecast)

If your TV Sony works on Android TV (2016 and newer models) you can use Google Cast for broadcasting from supported applications (YouTube, Netflix, Chrome).

Setting:

1. On TV:
   • Make sure it is connected to the same Wi-Fi network as your laptop.
   • Open an app that supports Cast (e.g. YouTube).
   • Click the Cast icon (📡) and select your TV.

1. IN Chrome click ⋮ → Broadcast.
2. Select Broadcast your desktop and indicate the TV.

⚠️ Please note: When casting your screen via Chrome, you may experience a delay of up to 2 seconds. This is critical for games or video chats – use Miracast or HDMI.

How to Fix the "Device Not Found" Error in Google Cast

If your TV doesn't appear in the list of devices for casting, try the following:

1. Reboot your router (sometimes multicast traffic is blocked after a long period of operation).

2. Disable IPv6 in your router settings (on some TP-Link models this solves the problem).

3. Set up static IP addressing for the TV in the router's DHCP settings.

4. Check if your antivirus (e.g. Avast) is blocking port 8008/8009 used for Cast.

5. Alternative methods: applications and adapters

If standard methods don't work, consider these options:

• 📱 Application ApowerMirror — broadcasts the screen via Wi-Fi even to older TVs Sony (requires installation on both devices).
• 🔌 Miracast adapter (For example, Microsoft Wireless Display Adapter) - connects to the TV's HDMI port and adds Miracast support.
• 🖥️ Steam Link - If you need streaming for games, this app provides minimal latency.
