Windows 10: Can't miracast from my PC to my Laptop, but can vice versa

When trying to Miracast my display from my PC to my Laptop, my laptop does not show up in the list.When trying to Miracast from my Laptop TO my PC, it shows up and works.They can both Miracast to my Firestick without issue.I have tried reinstalling the Project Screen optional add-on in Windows as well as drivers, both devices are on Windows 11, as I updated my Laptop to Win11 from 10 in order to try and fix it and they have the same miracast version.

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?

Does Miracast support 4K?

Hello,

We suggest that you check with the manufacturer of the 4k display device that you are using if it is certified to work with Miracast. If your display device is certified to work with Miracast, then check if your PC device supports Miracast. You may do so
