Hi,
My pc doesn't have built-in Wi-Fi so I connect it to a router with Lan cable and connect my laptop to the same router with Wi-Fi.
These two devices can see each other and I always use this way to share big files.
But when I want to use the laptop as a wireless display for my pc, I get an error "Check your Wi-Fi connection".
Why does it have to be a Wi-Fi connection?
While my PC was connected to the router by Lan, I connect a Wi-Fi USB dongle to my PC and without connecting it to the router, Now my PC can connect to my laptop, so windows just need to know that my PC has Wi-Fi and it doesn't matter that is connected or not.

'Wireless Display' has to be a wifi connection by definition. If it were supported on a wired ethernet connection, it would not be 'wireless'.

Yes, I can confirm Wireless Display is a peer-to-peer connection (Wi-Fi Direct), and does not need a router.
