Your Device Doesn T Support Miracast Windows 11 -

When Windows 11 reports that "your device doesn't support Miracast,"

it often stems from a software mismatch rather than a permanent hardware failure

. This error can appear even on devices that previously worked if a recent update installed generic drivers that lack Miracast's specific handshaking protocols. Microsoft Learn 1. Verify True Compatibility

Before troubleshooting, confirm if your hardware actually meets the technical requirements: Check via Settings your device doesn t support miracast windows 11

. If you see a list of displays, it is supported; otherwise, you'll see the "not supported" message. Check via DxDiag , and click Save All Information

Part 5: The Harsh Truth – When Your Device Truly Doesn't Support Miracast

Despite all the software fixes, some hardware genuinely cannot use Miracast. You are out of luck if:

Your PC is a desktop without a Wi-Fi adapter. Miracast requires a physical Wi-Fi chip. Ethernet alone won't work. You can buy a USB Wi-Fi adapter that supports Miracast for $15–20.
Your PC is very old (pre-2013). Intel 3rd Gen (Ivy Bridge) or older, or AMD pre-2014 APUs, lack the required WDDM 2.0 drivers.
You are using a Virtual Machine (VM). Miracast requires direct hardware access to the Wi-Fi radio. VMs (VirtualBox, VMware) cannot do this.

Fix #2: Roll Back or Update Your Wi-Fi Driver (The Real Culprit)

Windows Update frequently pushes generic Microsoft drivers that break Miracast. You need the manufacturer's specific driver.

For Intel users (most common):

Go to Intel's Download Center and download the Intel® Wireless Bluetooth® and Wi-Fi Drivers.
During installation, choose "Customize" and check "Clean Install".
Restart.

For all adapters (Manual rollback):

Device Manager > Network adapters > Right-click your Wi-Fi > Properties.
Driver tab > Roll Back Driver (if enabled). If not, click Uninstall Device.
Important: Check the box "Delete the driver software for this device".
Restart your PC. Windows will reinstall the default driver—hopefully a functional one.

Fix 2: Enable "NDIS6.20" or "Wireless Display" in BIOS

Some laptops disable Miracast at the BIOS level.

Reboot your PC, press F2/F10/Del (varies by brand) to enter BIOS.
Look for Wireless Display, WIDI, or NDIS6.20 under Advanced/Config/Network.
Set to Enabled, save & exit.
