1. Open the Start menu and click on Settings (the gear icon).

2. Click on System on the left side menu.
3. Click on Optional features from the main list.
4. Click the View features button next to the option to add an optional feature.
5. Type Wireless Display into the search box that appears.
6. Check the box next to Wireless Display when it shows up in the search results.
7. Click Next and then click Install.
8. Wait a few minutes for Windows to download and install the feature. Once the installation finishes, restart your computer to make sure the changes take effect.

Configuring Your Projecting Settings in 🪟 Windows 11

Configuring your projecting settings in Windows 11 requires opening the main Settings menu, selecting System, and updating your connection preferences so other devices can discover and share their screens with your computer safely without blocked permissions.

Follow these steps to change your projecting settings:

1. Open the Start menu and click on Settings.
2. Click on System on the left side menu.
3. Scroll down and click on Projecting to this PC.
4. If the settings on this page are greyed out and you cannot change them, look at the very top of the page for a link or message about optional features. You must install the Wireless Display feature mentioned in the previous section before these options become active.
5. Change the first dropdown menu from "Always off" to Available everywhere on secure networks or Available everywhere.
6. Change the second dropdown menu to First time only if you want your computer to ask for permission every time a new device connects, or choose "Every time connection is requested" for maximum security.
7. Set the PIN requirement to your preference. Setting it to require a PIN for pairing helps prevent nearby devices from connecting to your computer by mistake.

Launching the Receiver App and Connecting Your Devices

Advanced Troubleshooting: Fixing Greyed-Out Settings and Connection Failures

Fixing greyed-out settings and connection failures when projecting to your Windows 11 computer usually involves checking your network profile and ensuring your Wi-Fi and graphics drivers are fully up to date. These troubleshooting steps fix common blocks that prevent your computer from accepting wireless connections.

You can solve stubborn wireless projecting problems on Windows 11 by restarting the Wireless Display optional feature. To fix connection failures that prevent you from sharing your screen, open the Windows 11 Settings app, go to System, select Optional features, and remove the Wireless Display optional feature completely. After you restart your computer, reinstall the Wireless Display optional feature to clear corrupted system files and restore stable wireless connections.

• Network Profile Mismatch: Miracast requires both devices to be on a trusted network. If your Windows 11 computer thinks your Wi-Fi network is "Public" instead of "Private," it will block incoming wireless displays for security reasons. Open your network settings, click on your Wi-Fi properties, and ensure your network profile is set to Private.
• Graphics Driver Glitches: Because wireless projecting relies heavily on your graphics card to encode and decode video streams, outdated or corrupted graphics drivers will break the feature. Visit your computer manufacturer's website or Windows Update to install the latest graphics drivers.
• Firewall and Antivirus Interference: Sometimes, third-party security software blocks the specific network ports that Miracast uses to communicate. Try temporarily disabling your third-party antivirus program to test if it is causing the blockage.
• Airplane Mode Toggle: A quick trick that often resets stuck wireless adapters is turning Airplane Mode on for 10 seconds, then turning it back off. This forces your Wi-Fi and Bluetooth radios to restart and clear out minor glitches.
