Microsoft Wireless Display Adapter Stopped Working After Windows Update: Here’s Why
Problem:
Microsoft Wireless Display Adapter stopped working on my devices
- Surface Pro 8 and Samsung Book 12 both previously connected to my Microsoft Wireless Display Adapter via Miracast
- Both stopped working in early 2023 (error: “couldn’t connect”)
- Surface Pro 8 now shows as not Miracast-compatible
- Windows Update is current; Display adapter driver version 32.0.101.6737
- Surface Pro 8 runs Win11, Samsung Book 12 runs Win10
- The same adapter still works with another desktop PC on my home TV
- Suspect Windows updates removed or broke Miracast support
Question: Why did it stop working if it worked before, and how can I restore Miracast functionality on these devices?
Resolution:
Your devices haven’t lost hardware capability — Windows updates changed the software stack.
Miracast came pre-installed in Windows 10 and early Windows 11 versions, which is why it worked seamlessly on both your Surface Pro 8 and SamsungBook12 initially.
However, Microsoft changed this approach in 2023. In newer Windows 11 builds, Miracast was removed from the default installation and converted into an optional feature called “Wireless Display.” If this feature isn’t installed on your system, Windows won’t show Miracast as available, even if your hardware supports it.
Additionally, some manufacturers have quietly removed Miracast support through driver updates or firmware changes. This affects devices like the SamsungBook12 and certain Surface models after firmware updates. The result is that Windows reports these devices as “not compatible” with Miracast, despite the underlying hardware technically having the capability.
- Open Settings and navigate to Apps > Optional features > Add a feature. Search for “Wireless Display” and install it if it’s missing. After installation, restart both your Surface Pro 8 and SamsungBook12 before attempting to reconnect.
- Visit Intel’s support site to download the latest Wi-Fi and GPU drivers for your device. Windows Update sometimes provides outdated versions that may not fully support Miracast functionality.
- Download the Microsoft Wireless Display Adapter app from the Microsoft Store. Launch it to check whether firmware updates are available for your adapter.
- Disconnect both the HDMI and USB cables from your adapter, wait 10-15 seconds, then reconnect them. If possible, test the adapter with a different display to determine whether the issue is with your HDMI port.
- Check Network settings: Try connecting from home.
- You may consider Airtame.
