Starting in Windows 10 (WDDM 2.0), the operating system ships with a built-in Miracast stack that can work on any GPU. For information about the Microsoft Miracast stack and the requirements of drivers and hardware to support Miracast displays starting in Windows 10, see the following documentation:
The following table lists the wireless display (Miracast) user-mode functions that the operating system implements. Only Windows 8.1 Miracast user-mode drivers can call these functions. Pointers to the Miracast display callback functions are returned in a MIRACAST_CALLBACKS structure.
The following table lists the kernel-mode functions that display miniport drivers implement to support wireless (Miracast) displays in Windows 8.1. Pointers to the Miracast interface functions are returned in a DXGK_MIRACAST_INTERFACE structure.
Since the last update of my Intel UHD 620 Graphics device 27.20.100.9168 the wireless screen connection does not work anymore. I was tried with LG Smart TV Device and Samsung Galaxy S7+ (Android 11) tablet device. Last weeks ago I was able to connect to my LG Smart TV device, but since the last driver update does not work anymore, can you try to fix this issue?
I would like to let you know that the wireless display feature is handled by the Operating System (OS) and the laptop manufacturer (OEM) design, our recommendation for this cases is to always check with the OEM and Microsoft* directly. Intel graphics card and drivers do not handle wireless display technology.
We have not heard back from you, so we will close this inquiry. I would like to add that we previously tried reproducing this behavior as you can see on this other post -mirroring-wireless-display/m-p/1252333#M94009
In Windows 8.1, wireless display is a great way to share anything you do on Windows with friends and family in the living room, with colleagues in the conference room, and with students in the classroom. It lets you share experiences like shopping on Amazon or eBay, checking out 360-degree panoramas of vacation destinations in Bing Travel , solving puzzles in Disney Fairies with the kids, enjoying photos from a class field trip on SkyDrive, or exploring the solar system with your classroom with the World Wide Telescope. Of course, you can also use it for watching movies and videos through your favorite services like Netflix, Xbox Video and YouTube.
With wireless display in Windows 8.1, you can duplicate your main display or extend your display, giving you two independent screens (multi-monitor). Duplicating the display takes what you have on the local screen of your device and shows it on the big screen. Extending your display allows you, for instance, to use Microsoft PowerPoint to show a presentation in Presenter View, where the local screen shows you your speaker notes, next slide, and slide controls, while the wireless display shows the audience your full-screen presentation. Great for when you want to come from behind the podium, while keeping your notes and controls in the palm of your hand.
When you use wireless display, you have a source and a receiver: your Windows 8.1 device is the source, while your TV or projector is the receiver. If your display already has Miracast support, you are ready to go. If not, Miracast adapters provide an economical way to add wireless display to your existing TV or projector.
App developers do not need to change their apps to take advantage of wireless display. By default, all apps will just work with wireless display. We do however provide the ProjectionManager APIs, for developers who want to provide an enhanced experience with wireless display.
ProjectionManager APIs allow an app to detect a secondary monitor, and when the monitor is present, control what the app displays on the primary and secondary monitors. An example is a video or photo app, where the local screen shows the box shots, thumbnails, or playlist, while the wireless display shows the full-screen video or slide show. A game developer could provide controls for the game on the local device (e.g., cards in hand, steering wheel and cockpit controls) while the wireless display shows the action of the game on the big screen.
The ProjectionManager APIs are not specific to wireless display and work equally well for wired monitors. In either case, wireless or wired, what gets displayed on either screen is up to the app developer.
Since the content comes from (or via) the Windows device, only the Windows device needs Internet access, which can come via its Wi-Fi, mobile broadband, or wired connection. Additionally, since we enabled wireless display in the OS and not tied to any particular application, any content in any app can take full advantage of the processing power of the PC, which enables a good wireless display experience across the range of Windows 8.1 devices and form-factors.
We are excited to have worked with our partners and the industry in bringing you a great, no compromise, and standards-based, approach to wireless display. We look forward to hearing about your experiences as you project your full Windows experience onto the big screen! Please let us know your thoughts by leaving us a comment.
Did all of these computers receive an update (through Windows Update the day of the crash)? Have you tried rolling back those updates? Have you tried rolling back drivers to their display devices? Have you tried installing new drivers? Are these three Windows devices the same hardware (Dell, Lenovo, etc)?
Additionally, make sure that your Windows 7 device is within the range of the adapter for a strong and stable wireless connection. Avoid interference from other wireless devices and ensure that your display settings are configured correctly.
Historically, Microsoft wireless display adapters have undergone continuous development to enhance compatibility with different Windows versions. These adapters have provided users with the convenience of wirelessly connecting their Windows 7 devices to external displays, which has greatly improved productivity and flexibility in various scenarios.
In my case any time I try to update the software/driver on the Radeon R9 270 and I try to connect to a wireless display (Samsung smart TV series 6 40) it attempts the connection and disconnects right away. When I revert the driver to 22.19.172.269 the Miracast connection works fine again. Last I tried was driver 25.20.14011.1003 dated 11/7/2018.
I also did an Amdcleanup uninstall of the old AMD software and driver and tried the latest software and driver WHQL Radeon Adrenalin 18.11.2 with R9 270 driver 25.20.14011.5005 dated 11/16/2018, this again fails and disconnects the wireless display right away.
I would recommend checking out this thread, you may have firewall issues possibly? Honestly I doubt that is the case, but its worth a shot:

This installer has hardware and software requirements outlined for use with Intel Wireless Display software. It is also recommended that the correct wireless and graphics drivers be installed on the PC prior to installing the Intel Wireless Display Software.
Basically the whole process : I changed the way i connect my pc to wi-fi with a better wi-fi card and then i updated wi-fi bluetooth drivers for my wi-fi card, or from windows don't remeber exactly what control those ..
To set up the wireless display, connect the laptop or computer to a nearby Wi-Fi router. If you use a laptop that is new and hasn't yet been set up with a Windows Live Connection, then the best way to go about setting this up is to go into the control panel and click on 'network settings' then click on 'internet options'. Once you have done this you will see a series of three boxes - one for the SSID, one for a password, and one for your network's name. Give the name a nice name like'sbmi1' without any spaces in it, and click on 'OK'.
Regardless of the case, setting up an external display is typically easy. However, sometimes, you may run into the issue where the operating system can't detect a second or third monitor as a result of hardware or driver problems. If you experience any problems connecting an external monitor, there are many things you can try to troubleshoot and resolve this issue without calling technical support.
