Step 2: On the "Optional Features" page, click "View Features" next to "Add an optional feature.” Search for "Wireless Display," then click and install it.


Step 3: Once installed, go back to "Settings" >> "System" >> "Projecting to this PC" to manage your projection preferences.


Step 4: On the computer you want to share the screen to, search for "Wireless Display" in the taskbar search box and launch the app. The device will now be discoverable and ready to receive projected content.


Step 5: Press "Windows+K" on the computer you want to share screen from, select the device you want to share screen to on the device list that pops up.

You can also project your computer screen to a Miracast-enabled TV, projector, or other type of external display.

Conclusion

This article introduced two simple methods for projecting and sharing your screen on Windows 10/11. While Method 2 uses built-in Windows tools, the setup process is relatively complicated and is only applicable to Windows systems or displays that support Miracast. If you want to project your Windows computer screen to any macOS, iOS, Android, or Windows device, we recommend using the remote software DeskIn. It is not restricted by the operating system and does not require devices to be on the same network, making it a versatile solution for all your projection needs
