Windows 10: Can't use Miracast when connected to Ethernet

Surface Pro 7 connected to Surface Dock 2. The Wi-Fi adapter cannot be enabled while the Ethernet adapter is enabled. Window Key + K Miracast cannot detect wireless monitors while Wi-Fi adapter is disabled.Trading network connection speed and reliability for wireless monitors should NOT be a choice. Instead of disabling the Wi-Fi adapter while the Ethernet adapter is enabled; allow the Wi-Fi adapter to be enabled and disallow Wi-Fi network connections operate in a lower functionality setting and allow protocols like Miracast to connect, maybe via "Advanced Options"; such as "Allow/Enable M

Miracast over ethernet

If you want to suggest this to Microsoft you can use the Feedback Hub app in Start Menu where developers are tasked to process consumer feedback and may interact with you. But Microsoft will not even see it here because this is a tech forums where we are mostly volunteers trying to help solve your problems.



If you don't want to try connecting PC to TV over home network, then I found more resources for using Miracast over Ethernet:

Miracast over Ethernet PC to Wi-Fi Laptop

I'm facing with the issue by 'Miracast over infrastructure' feature. I nave read a plenty of posts over the Internet enabling integrated graphics and updating every driver related to this feature.

The idea is to share laptop display as secondary display for PC. Here is the infrastructure for connection:

PC (Miracast Source) - Gigabit LAN - Router Asus RT-AC68U - 5GHz WLAN - Laptop Asus UX501VW (Miracast Sink).

The laptop is Miracast ready so there is no need to display the specs at this step.

Turning to my self-built PC it's "This device doesn't support receiving miracast" in "Projecting to this PC" tab.

The specs of my PC are:

• GPU: Nvidia GTX 1080 (driver 398.36) and specially enabled Intel HD Graphics 530
  (driver 23.20.16.4973);
• Motherboard: Asus Z170 Pro Gaming with onboard LAN;
• CPU: Intel Core i7-6700K;
• Windows 10 Pro 1803 (17134.137 build).

The DXDIAG report shows that PC is Miracast-ready in general, but:

1. Nvidia GTX 1080 stands for [Miracast: Not Supported]
2. Intel HD Graphics 530 stands for [Miracast: Not Supported by WiFi driver].

What is basically true as well as there is no WLAN card in my PC box in general. So there is a question about the steps to allow the wired network work with Miracast feature by configuring PC/router, because there is only some technical stuff about 'Miracast
over infrastructure' like
this .

Speaking about requirements stated there:

• [+] Device is running Windows 1803;
• [+] Both PC and laptop are connected to same network stated as Private;
• [?] The device must have a Wi-Fi interface enabled in order to respond to discovery requests -
  What shall I do with my Ethernet connection to respond to discovery requests?

Both PC and laptop are visible for each other in Network tab in File manager, so there are several folders under network share from PC to laptop using smb protocol.

So basically, is it technically possible to enable the 'Miracast over infrastructure' with this hardware, or there is a strong need to buy the WLAN card inside my PC box to allow the respond to discovery requests and
the is no way to work for Miracast over wired connections?

 

Trouble with Miracast over ethernet

I found this link saying that Miracast is supported over an ethernet connection. I tried doing so with my Ethernet connected desktop
and WiFi connected laptop to avail.

Did I misinterpret the document? Is Miracast not actually supported over LAN?

If I did not, what could I have done wrong with trying to use it? How can I troubleshoot?
