Dec 22, 2020 Get current Miracast drivers for your PC Windows 10. Step 1: Download Intel Driver Update Utility Tool from Miracast Driver Download Page or just go to Official Intel Site. Step 2: Locate the download folder and click on the. Exe file to run it. The Driver tab shows the driver as a Microsoft driver dated 6/21/2006, version 10.0.17134.1. The 'Driver Details' button opens a 'Driver File Details' window showing the driver file as 'C: WINDOWS system32 DRIVERS monitor.sys'. In the Driver tab, only the 'Driver Details' button is active; the others, including 'Update Driver', are grayed out.

This document describes how drivers can implement a custom Miracast stack in Windows 8.1. As of Windows 10, the OS ships with a built-in Miracast stack that can work on any GPU and it is no longer recommended that drivers implement a custom Miracast stack. This documentation is therefore deprecated and Microsoft may remove support for custom Miracast stacks in a future version of Windows.

Wireless (Miracast) displays can optionally be supported by Windows Display Driver Model (WDDM) 1.3 and later drivers. This capability is new starting with Windows 8.1.

Wireless (Miracast) displays can only be supported by Windows Display Driver Model (WDDM) 1.3 and later models. The easiest way to update your Intel WIDI Windows 10 is to download and install the Intel Driver Update Utility Tool. This tool automatically checks and updates your drivers to the latest version.
Miracast is already available in Windows 8.1 and Windows 10. You can share your screen through HDMI and WIFI. Miracast for windows 8.1 and 10 has already inbuilt with this technology. But if you are using windows 7 version then you need to do some setup. Because the miracast for windows 7 is still not released.

For more information on the requirements of drivers and hardware to support Miracast displays, refer to the Building best-in-class Wireless Projection solutions with Windows 10 guide and the relevant WHCK documentation at Device.Graphics.WDDM13.DisplayRender.WirelessDisplay.

Miracast design guide

Sig sauer serial number search. These design guide sections describe how display miniport drivers and Miracast user-mode drivers support Miracast displays:

Miracast reference

These reference sections describe how to implement this capability in your drivers:

User-mode device driver interfaces (DDIs)

Wireless display callback functions called by Miracast user-mode drivers

The reference pages in this section describe wireless display (Miracast) user-mode functions that the operating system implements. Only Miracast user-mode drivers can call these functions.

Pointers to the Miracast display callback functions are returned in a MIRACAST_CALLBACKS structure.

Topic	Description
PFN_GET_NEXT_CHUNK_DATA	Provides info about the next Miracast encode chunk that was reported to the Microsoft DirectX graphics kernel subsystem when the DXGK_INTERRUPT_TYPE interrupt type is DXGK_INTERRUPT_MIRACAST_CHUNK_PROCESSING_COMPLETE.
PFN_MIRACAST_IO_CONTROL	Called by the user-mode display driver to send the kernel-mode display miniport driver a synchronous I/O control request.
PFN_REGISTER_DATARATE_NOTIFICATIONS	Called by the user-mode driver to register with the operating system to receive network quality of service (QoS) notifications and the current network bandwidth of the Miracast connection.
PFN_REPORT_SESSION_STATUS	Called by the user-mode display driver to report the status of the current Miracast connected session.
PFN_REPORT_STATISTIC	Called by the user-mode display driver to report the statistics of the Miracast link to the operating system.

Wireless display functions implemented by Miracast user-mode drivers

Miracast Driver For Windows 10 64 Bit 32 Bit

The reference pages in this section describe wireless display (Miracast) functions that a Miracast user-mode driver must implement. This type of driver runs in a standalone DLL.

In response to an operating system call to the QueryMiracastDriverInterface function, the Miracast user-mode driver must supply pointers to these functions in the MIRACAST_DRIVER_INTERFACE structure, except for pfnDataRateNotify, which is has a pointer declared in RegisterForDataRateNotifications.

Topic	Description
PFN_CREATE_MIRACAST_CONTEXT	Called by the operating system to create a user-mode Miracast context.
PFN_DESTROY_MIRACAST_CONTEXT	Called by the operating system to destroy a user-mode Miracast context.
PFN_HANDLE_KMD_MESSAGE	Called by the operating system to handle the asynchronous kernel-mode message that the Miracast user-mode driver receives when the display miniport driver calls the DxgkCbMiracastSendMessage function.
PFN_DATARATE_NOTIFICATION	Called by the operating system to notify the Miracast user-mode driver that the bit rate of the Miracast network link has changed. This function is registered with the operating system when the RegisterForDataRateNotifications function is called.
QUERY_MIRACAST_DRIVER_INTERFACE	Called by the operating system to query the Miracast user-mode driver interface, MIRACAST_DRIVER_INTERFACE.
PFN_START_MIRACAST_SESSION	Called by the operating system to start a Miracast connected session.
PFN_STOP_MIRACAST_SESSION	Called by the operating system to start a Miracast connected session that had earlier been started by a call to the StartMiracastSession function.
