Unable to Connect Windows PC to Samsung TV via Wireless Display

I am experiencing an issue where my Windows 10 PC cannot connect to my Samsung Crystal UHD TV via Wireless Display. The connection always fails with the error "Connection Failed." However, my phone is able to stream to the TV without any issues, indicating that the TV's wireless display functionality is working properly.

Here are the steps I’ve taken so far to try to resolve the issue:

  1. Ensured that both my PC and TV are on the same Wi-Fi network.
  2. Verified that my TV supports screen mirroring and is in the correct mode.
  3. Updated Windows 10 to the latest version, including all cumulative updates.
  4. Updated all drivers on my PC, including network and display drivers.
  5. Enabled TLS 1.0 through TLS 1.3 in the Internet Options.
  6. Restarted both devices multiple times and reset the TV's network settings.
  7. Temporarily disabled the firewall and antivirus on my PC.

Despite all of this, the connection still fails. This issue seems isolated to my PC since other devices (e.g., my phone) connect to the TV successfully.

  • TV Model: Samsung Crystal UHD 65".
  • PC Details:
    • Windows Version: Windows 10 Pro (latest updates installed).
    • Processor: (Intel Core i9 14900k).
    • Wi-Fi Adapter: (Intel(R) Wi-Fi 6E AX211 160MHZ).
    • Graphics Card: (NVIDIA GeForce RTX 3080 Founder's).
  • ADDITIONAL INFORMATION:
  • The TV appears in the wireless display list on my PC, but selecting it always results in a "Connection Failed" error.
  • I’m looking for further troubleshooting steps or confirmation if this is a compatibility issue between Windows 10 and Samsung TVs.

    Hi Welcome to Microsoft community.Given the detailed steps you've already taken to troubleshoot the issue of connecting your Windows 10 PC to your Samsung Crystal UHD TV via Wireless Display, here are some additional steps and considerations to explore:

    1. Check Wi-Fi Band:
      • Ensure both your PC and TV are connected to the same Wi-Fi band (2.4GHz or 5GHz). Some devices might have issues with dual-band networks. You might try connecting both to the 2.4GHz band since Miracast typically uses this frequency.
    2. Wi-Fi Direct:
      • Confirm if your TV supports Wi-Fi Direct. If it does, try to connect using this method. Sometimes, standard Wi-Fi issues can be bypassed using Wi-Fi Direct.
    3. Miracast Support:
      • Although you've updated drivers, double-check if your Wi-Fi adapter supports Miracast. The Intel Wi-Fi 6E AX211 should support it, but sometimes specific configurations or BIOS settings might disable or limit this feature. Look in your PC's BIOS/UEFI settings for Wi-Fi options.
      • Disclaimer:  Microsoft provides no assurances and/or warranties, implied or otherwise, and is not responsible for the information you receive from the third-party linked sites or any support related to technology.   If you are going to modify BIOS Settings, please back up all your personal files first to ensure you do not lose data.
    4. Power Management Settings:
      • Go to Device Manager, find your network adapter, and check its properties. Under the "Power Management" tab, ensure that "Allow the computer to turn off this device to save power" is unchecked. Power-saving modes can sometimes interfere with wireless connections.
    5. Network Reset on PC:
      • In Windows settings, under "Network & Internet," there's an option to reset network settings. This can sometimes resolve deep-seated network configuration issues.
    6. Check for Known Issues:
      • Look for any known issues or compatibility problems with your specific TV model and Windows 10 version on Samsung community forums. Sometimes, there are model-specific or version-specific issues documented.
    7. Firmware Update for TV:
      • Ensure your Samsung TV has the latest firmware. Sometimes, TV manufacturers release updates that address connectivity issues.
    8. Physical Interference:
      • Check for physical obstructions or interference between your PC and TV. Wireless signals can be weak or interrupted by walls, furniture, or other electronic devices.
    9. Driver Rollback or Specific Driver Version:
      • If you recently updated your drivers, consider rolling back to a previously stable version or look for specific driver versions known to work well with Miracast.

    Compatibility Considerations:

    • Since your phone connects without issues, this leans towards a software or specific hardware configuration problem on your PC side.
    • NVIDIA GPUs have had mixed reviews with Miracast; some users find better success using the Intel integrated graphics for these connections. You can switch to the Intel GPU for this purpose in the Graphics Settings of Windows.

    If after these steps you still face issues, it might indeed indicate a compatibility problem:

    • There could be an inherent compatibility issue between the specific hardware/software combination of your PC and the TV's Miracast implementation. This isn't common but can happen.
    • Provide feedback via Samsung's support channels about this issue. This can help in identifying if it's a widespread problem needing attention.

    If all else fails, consider using a wired HDMI connection as a reliable alternative until a software update might resolve the Miracast issue.Best regardsDerrick Qian | Microsoft Community Support Specialist
