- WiFi issues, Miracast firmware and Windows 10 itself could be the cause of the problems but it’s not encouraging when Miracast support and devices have been around for so long. Given that there are now other options than Miracast and that a TV can be made ‘smart’ at so little cost, Miracast doesn’t have the rosiest looking future.
- Miracast free download - Miracast Display Finder, Miracast App, Miracast Screen Sharing/Mirroring Shortcut, and many more programs.
- Miracast is easy to use for Windows 10, and there are many devices that come with a built-in Miracast support, making connecting to your PC easy. Here, we’ll show you how you can use Miracast to connect your Windows 10 PC to your TV or other devices. How Miracast Works. Miracast is a technology built into Windows 10 PCs. It allows your PC to.
Note
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.
Also, considering the issue occurred after the recent windows 10 update, it seems to be an issue with the driver and I recommend you update them using the below steps: I suggest you to update the Miracast Wireless Display adapter from the Device manager manually by following the steps below and check if the issue is resolved. 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.
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.
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.

Standards-based Miracast advances life without wires
Miracast is an industry-wide solution, allowing technology to work across device types and vendors. Connections are easy to set up and use since Miracast devices choose the appropriate settings automatically. Miracast can connect two devices using network infrastructure or Wi-Fi Direct®. When content to be shared is stored on a Miracast-certified device, such as a smartphone to an automobile infotainment display, a Wi-Fi network connection is not required.
Only devices marked Wi-Fi CERTIFIED Miracast have been certified by Wi-Fi Alliance® to work well with other Wi-Fi CERTIFIED™ devices, employ the latest security protections, and deliver a high-quality user experience.

- Are Wi-Fi CERTIFIED products protected by security?
As of July 1, 2020, all new Wi-Fi CERTIFIED devices require WPA3. The only way to be sure that a product meets the latest security standards is to purchase only Wi-Fi CERTIFIED products.
- How does Wi-Fi Alliance help ensure product compatibility and a good user experience for certified products?
Compatibility and quality are achieved through testing of Wi-Fi products. Consumers should always look for the Wi-Fi CERTIFIED logo to ensure the best user experience possible.
- What has changed in Miracast since its original release?
New enhancements focus on high-definition (HD) content, increased performance, and better battery life for Miracast devices.
- Is a Wi-Fi connection needed to stream a video from the internet?
Miracast is unique to other wireless display solutions in that a direct peer-to-peer connection between two devices may be formed to share content residing on the source device, without the need for a Wi-Fi network. If streaming content from the internet, a network connection is required.
- Does Miracast support devices like wireless speakers? (audio only)
Audio-only devices are not part of the Miracast certification program.
- How does Miracast protect premium content?
Miracast provides industry-standard protection of premium content through support of High-bandwidth Digital Content Protection (HDCP). HDCP is a wireless adaptation of the same trusted content protection mechanisms widely used for cabled interfaces, providing diversity in premium content options. This feature is designed to protect the digital rights of content owners and to encourage their efforts to make their content available.
- What formats does Miracast support?
Miracast supports many commonly used audio/video format. For a complete list, download the Miracast Technical Overview.
- How is Miracast related to Wi-Fi Direct?
Wi-Fi Direct allows devices to connect directly to each other, without the need for a Wi-Fi access point (AP). It simply requires the push of a button or the entry of a PIN. Wi-Fi Direct allows source and display devices to discover one another and provides the underlying device-to-device connectivity for Miracast. Miracast builds upon Wi-Fi Direct with mechanisms to negotiate video capabilities, setup content protection (if needed), stream content, and maintain the video session.
- What features does Miracast certification test?
Miracast certification includes testing for audio/video (A/V) latency, quality, and synchronization offset. Testing ensures that devices operate across vendors, provide simplified discovery and setup, meet the minimum display resolution requirement, and implement content protection (when implemented). Miracast devices are also tested for implementation of WPA2™ security. Wi-Fi Alliance members may view details on certification testing in the Wi-Fi CERTIFIED Miracast Test Plan.
- Must both the content source and display be Miracast devices?
Both the display and the source devices must be Miracast certified. Miracast may be used on devices without embedded Wi-Fi capability by using a Miracast-certified adapter that supports an interface such as High-Definition Multimedia Interface (HDMI) or Universal Serial Bus (USB).
- What types of equipment are tested?
Miracast certification is available for video-capable devices such as TVs, handsets, tablets, laptops, set-top boxes, cameras, and projectors.
- What is the difference between Miracast and Wi-Fi Display?
Miracast is the brand for the certification program operated by Wi-Fi Alliance. Devices that pass this certification testing can be referred to as “Wi-Fi CERTIFIED Miracast™ devices” or “Miracast® devices”. Miracast certification is based on the Wi-Fi Alliance Wi-Fi Display Technical Specification. This is the underlying specification developed by Wi-Fi Alliance members, and is copyrighted and owned by Wi-Fi Alliance.
- How do I activate TDLS?
Two Wi-Fi CERTIFIED TDLS devices will automatically form a direct connection after linking to the Wi-Fi network. No user interaction is required.
