Hi, ZHENYUZENGGTV!
My name is Caio. I'm an Independent Advisor and I'll be glad to help you today.
Before trying to install Wireless Display, please check if you have the Media Feature Pack installed in your PC, since you're running Windows 10 Pro N, which doesn't include media-related technologies (you can learn more about it at https://support.microsoft.com/en-us/topic/media...). So, please follow the steps below:
> Press Windows key +i on your keyboard
> Select Apps
> In the right panel, go to Optional features
> Click on + Add a feature
> In the list, search for Media Feature Pack
> Check it and install
> Reboot your PC
> Try repeating the steps suggested by Bianca to install the Wireless Display Feature
I hope this helps you! Please let me know if I can assist you more.
Best regards,
Caio G.
