Connecting a Computer to a Sony Bravia TV via Wi-Fi: 4 Proven Methods + Troubleshooting

Wirelessly broadcast your screen from your computer to Sony Bravia via Wi-Fi opens up new possibilities: watching movies in 4K HDR, streaming games without an HDMI cable, or showing presentations without adapters. However, many users encounter issues, from lack of signal to image lag. In this article, we'll explore all current connection methods (including hidden functions Bravia), we will compare them in terms of speed and stability, and also provide checklists for troubleshooting.

It's important to understand that the connection method depends on the TV model, PC operating system, and even the firmware version. For example, Sony Bravia X90J (2021+) supports Miracast out of the box, and for older models (XF90 2019) a workaround may be required through DLNA or third-party applications. We tested all options on Windows 11, macOS Ventura, and Linux Ubuntu—the results are summarized in the comparison table below.

1. Method 1: Miracast (Wireless Display) - a native solution for Windows

Miracast is a wireless video streaming standard built into Windows 10/11 and most modern Sony Bravia (starting with the series X800H 2020). Advantages of the method: minimal delays (up to 30 ms) and support for resolutions up to 4K@30HzHowever, there are some nuances:

  • 🖥️ Your PC must have a Wi-Fi adapter that supports it. Wi-Fi Direct (check in Device Manager → Network adapters).
  • 📺 On TV the function is called Screen Mirroring or Wireless Display (path: Settings → Devices → Screen Mirroring).
  • 🔄 Both devices must be on the same Wi-Fi network or connected directly (in mode Wi-Fi Direct).

Step-by-step instructions:

  1. On TV: turn on Screen Mirroring in the settings and select the mode Connecting via Wi-Fi.
  2. On PC: Click Win + K, choose yours Sony Bravia from the list of available displays.
  3. Confirm the connection on your TV (you may be asked to enter a PIN).

The PC's Wi-Fi adapter supports Miracast (check via dxdiag → tab Save All Information)

The TV has been updated to the latest firmware (valid for 2020-2023 models)

VPNs and firewalls are disabled on your PC (they may be blocking the connection)

The distance between devices is no more than 5 meters (for a stable signal)

-->

If your TV doesn't appear in the list, try:

  • Reboot your router (sometimes DHCP conflicts prevent devices from being discovered).
  • Add device manually via Settings → System → Display → Advanced display settings → Wireless display.
  • Update the Wi-Fi adapter driver on your PC (especially relevant for laptops with Intel AX200/AX210).
Why might Miracast not work on older Sony Bravia models?

Televisions Sony Bravia 2018 and earlier releases often use a proprietary protocol WiDi (Intel Wireless Display) instead of Miracast. In this case, you will need:

1. Install the program on your PC Intel Wireless Display (Intel official website).

2. In the TV settings, select the mode Intel WiDi instead of Screen Mirroring.

3. Connect via the utility, not via Win + K.

2. Method 2: DLNA – for media files (videos, photos, music)

If you need to broadcast media content only (movies, photos, music), rather than the entire screen, the best option is DLNA (Digital Living Network Alliance). This protocol is supported by all Sony Bravia since 2012. Main advantages:

    • Make sure both devices are on the same subnet (eg. 192.168.1.x).
    • Turn it off AP Isolation in the router settings (this blocks data exchange between devices on the network).
    • Update your TV's firmware - DLNA may not work reliably in older versions. HEVC (H.265) video.

    • 🎮 Controllers: DualSense (PS5), Xbox Series X, keyboard/mouse.
    • 🖥️ Permissions: up to 4K@60Hz (requires Wi-Fi 6 or wired TV connection).
    • 🔧 Settings: Manual bitrate and codec optimization (HEVC/AV1).

    Setup instructions:

    1. Install Steam on PC and Steam Link on TV (available in Google Play Store For Sony Bravia with Android TV).
    2. On PC: Turn on Streaming in Steam settings (Settings → Online → Streaming).
    3. On TV: Launch Steam Link, connect to PC and select the game.
