1] 什么是 Miracast

Miracast是从笔记本电脑、平板电脑、智能手机等设备无线连接到外部显示器或电视^(TVs)或监视器等大屏幕的标准。它可以广义地描述为“ HDMI over Wi-Fi”，取代了从设备到显示器的电缆，使其在无线网络上工作。

如今， Miracast支持已内置到设备中，并且首先在Windows 8.1中提供。使用Miracast，您可以轻松地在计算机和其他显示设备（如显示器、电视^(TVs)和投影仪）之间建立无线连接。Miracast允许发送高达 1080p 高清视频（H.264编解码器）和 5.1 环绕声，这对于普通用户来说已经足够了。

使用Miracast^(Miracast)有很多优点。该列表包括更快的内容投影、在现有网络上工作、与较旧的无线硬件一起工作以及自动检测接收器支持。但是，它并不是要取代旧的连接到投影仪的方式，而是提供一种现代的方法，即无线技术，如果您拥有正确的硬件集的话。

2]如何^(How)检查您的设备是否支持Miracast

按键盘上的“Win+R”，然后输入“ dxdiag ”并按 Enter。

按^(Press)位于底部的“保存所有信息”按钮并将文本文件保存在所需位置。^(Save)

现在打开文本文件并查找“Miracast”，旁边是当前的可用性状态。

检查Miracast^(Miracast)支持的另一种方法是转到显示^(Display)设置（Windows 10Settings > System > Display）。到达那里后，在Multiple Displays^{(Multiple Displays)}下查找Connect to a wireless display ，然后单击Detect按钮。

3]如何^(How)为您的 PC获取当前的Miracast驱动程序^(Miracast)

这些方法适用于直接支持Miracast或通过第三方Miracast硬件支持的显示器。后者可以使任何显示器成为具有Miracast功能的设备。

Microsoft在 Microsoft Store 中提供了一个应用程序——Microsoft^{(Microsoft Store—)}无线显示适配器^{(Microsoft Wireless Display Adapter)}——你可以安装它。安装后，如果它支持开箱即用的Miracast，它还将安装适用于您当前显示器的无线驱动程序。

如果显示器不支持Miracast，那么您可以使用外部设备。根据OEM的不同，Windows应该能够下载并安装驱动程序。如果没有，您可以转到Windows 10 Settings > Update和Security > Click可选^{(Optional Updates)}更新。

找到第三方Miracast适配器或Miracast Receiver的驱动程序，然后安装它。您也可以直接从OEM网站下载该软件并进行安装。

4]在Windows PC上设置^(Set)和使用Miracast

第 1 步：^{(Step 1:)}如果您的电视内置Miracast支持，请将其打开。或者将外部适配器连接到电视的HDMI端口并打开电源。

第 2 步：^{(Step 2:)}现在在您的Windows PC 上，导航到Start -> Settings -> Devices -> Connected Devices。

第 3 步：^{(Step 3:)} 单击^(Click)“添加设备^(Device)”并等待适配器出现在列表中。单击^(Click)接收适配器，仅此而已。您已设置无线显示。

您现在可以通过按“ Win+P ”并选择相关选项来配置两个显示器。

如果这对您不起作用，请再次重复这些步骤并检查。^{(If that does not work for you, repeat the steps again and check.)}

5]如何将您的^(How)Windows PC无线投影到高清电视^(HDTV)

现在该设备可用作您可以镜像或投影计算机的外部显示器之一，请按照以下步骤进行投影。

第 1 步：^{(Step 1:)}打开操作中心^{(Action Center)}，然后单击项目选项。您也可以使用Windows + P

第 2 步：^{(Step 2:)}这将弹出用于复制或扩展显示的选项。最后，单击连接到无线显示器^{(Connect to a Wireless Display)}链接。

第 3 步：^{(Step 3:)}这将打开另一个弹出窗口，可以使用 Wi-Fi 连接扫描新设备，并列出旧的连接屏幕。选择您之前配置的设备。连接后，您的 Windows 10 设备现在应使用视频流通过WiFi网络进行镜像。^(WiFi)

注意：即使您的笔记本电脑连接到Ether，这也可以使用，因为它将使用无线适配器进行投影。

6] Windows Miracast 不工作

有时您在使Miracast工作时遇到问题，例如您可能会收到一条不受支持的消息或可能没有声音。试试这些建议：

1. 如果连接不适合您，您需要检查的第一件事是您的设备驱动程序。确保所有Display和Wi-Fi驱动程序都是最新的，并且您的计算机支持Wi-Fi direct。
2. 如果更新和安装正确的驱动程序后问题仍然存在，则建议尝试另一个适配器^(Adapter)。我会推荐微软无线显示适配器^{(Microsoft Wireless Display Adapter)}。由于^(Due)许多制造商和可用的产品种类繁多，可能存在任何兼容性问题。
3. 确保^(Make)您在安全的 Wi-Fi 网络上进行设置。它可能无法在开放的Wifi网络上运行。
4. 解决方案的最后一步也是最后一步是咨询相应的制造商并寻求问题的可靠解决方案。

如果Miracast 在更新后无法在 Windows 10 上运行，^{(Miracast is not working on Windows 10 after an Update)}这篇文章将为您提供帮助。

我希望这篇文章对您有所帮助，并且您能够清楚地理解这个概念，并在Windows 11/10Miracast。设置好后，您就可以在稳定的流媒体上播放您最喜欢的游戏了。相同的Miracast设备也可以与使用屏幕共享选项的Android设备一起使用。^(Android)

Windows 10 是否支持 Miracast？

是的，Windows 10确实支持Miracast。自 2015 年推出以来， Windows 10能够将您的屏幕镜像到与流行的^{(Windows 10)}Miracast标准兼容的任何加密狗或设备（例如流媒体盒、电视）。您还可以让您的 PC 成为无线显示器，接收来自的Miracast信号手机、平板电脑或其他Windows 10笔记本电脑或台式机。

如何修复Windows 10不支持的Miracast？

确保您的设备与 Miracast 兼容。看到两个设备上都启用了Wi-Fi 。如果这不能解决问题，请检查Wireless Mode Selection是否设置为Auto。很少^(Few)有修复是启用英特尔集成显卡^{(Enable Intel Integrated Graphics)}并重新安装^(Reinstall)无线网络适配器^{(Wireless Network Adapter)}驱动程序。

修复^{(Fix for)}：您的 PC 或移动设备不支持 Miracast^{(Your PC or mobile device doesn’t support Miracast)}，因此无法进行无线投影。

Miracast for Windows 11/10: How to Setup & Check for Support

In this post, we will go through the following sections to clearly understand the concept of Miracast, how you can set up, install apps and drivers, and then learn to project it. In the end, we will also share how you can troubleshoot if Miracast is not working as expected.

1. What is Miracast
2. How to check if Miracast is supported on your device
3. How to get current Miracast drivers for your PC
4. Set up & use Miracast on Windows 11/10
5. How to wirelessly project your Windows PC to an HDTV
6. Windows Miracast not working

You may need administrator permission to install the driver and apps.

1] What is Miracast

Miracast is a standard for wireless connections from devices like laptops, tablets, smartphones, etc., to external displays or larger screen like TVs or monitors. It can broadly be described as “HDMI over Wi-Fi”, replacing the cable from the device to the display and making it work on a wireless network.

Nowadays Miracast support comes built into the device, and it was first offered in Windows 8.1. With Miracast, you can easily create a wireless connection between your computer and other display devices such as Monitors, TVs, and Projectors. Miracast allows sending up to 1080p HD video (H.264 codec) and 5.1 surround sound which is more than enough for average users.

There are many advantages of using Miracast. The list includes faster content projection, works over the existing network, works with older wireless hardware, and automatic detection of receiver support. However, it is not here to replace an older way to connect to projectors but offers a modern approach i.e. wireless technology, if you have the right set of hardware.

2] How to check if Miracast is supported on your device

Press ‘Win+R’ on your keyboard and then type in ‘dxdiag’ and hit Enter.

Press the ‘Save all Information’ button located at the bottom and save the text file at the desired locations.

Now open the text file and look for ‘Miracast’ and next to it will be the current availability status.

An alternate way to check Miracast support is by going to Display settings (Windows 10 Settings > System > Display). Once you are there, look for Connect to a wireless display under Multiple Displays and click on the Detect button.

3] How to get current Miracast drivers for your PC

These methods apply to displays that directly support Miracast or support through third-party Miracast hardware. The latter can make any display a Miracast capable device.

Microsoft offers an app available in the Microsoft Store—Microsoft Wireless Display Adapter—that you can install. Once installed, it will also install the wireless driver that will work with your current display if it supports Miracast out of the box.

If the display doesn’t support Miracast, then you can use an external device. Depending on the OEM, Windows should be able to download and install the driver. If not, you can go to Windows 10 Settings > Update and Security > Click on Optional Updates.

Locate the driver for the third-party Miracast adapter or Miracast Receiver, and install it. You can also download the software directly from the OEM website and install it.

4] Set up & use Miracast on Windows PC

Step 1: If your TV comes with built-in Miracast support, then turn it On. Else connect the external adapter into the HDMI port of your television and power it on.

Step 2: Now on your Windows PC, navigate to Start -> Settings -> Devices -> Connected Devices.

Step 3: Click on ‘Add a Device’ and wait for the adapter to appear in the list. Click on the receiving adapter and that’s all. You’ve set up the wireless display.

You can now configure both the displays by pressing ‘Win+P’ and selecting a relevant option.

If that does not work for you, repeat the steps again and check.

5] How to wirelessly project your Windows PC to an HDTV

Now that the device is available as one of the external displays to which you can mirror or project your computer, follow these steps to project.

Step 1: Open the Action Center, and click on the Project option. You can also use Windows + P

Step 2: This will bring up the option which is used to duplicate or extend the display. In the end, click on the Connect to a Wireless Display link.

Step 3: This will open another flyout where new devices can be scanned using the Wi-Fi connection, and the older connected screen will be listed. Select the device you have configured earlier. Once connected, your Windows 10 device should now be mirrored over the WiFi network using a video stream.

Note: This works even if your laptop is connected to Ether as it will use the wireless adapter to project.

6] Windows Miracast not working

Sometimes you face problems in making Miracast work like you may get a not supported message or there may be no sound. Try these suggestions:

1. If the connection doesn’t work out for you, the first thing you need to check is your device drivers. Ensure that all the Display and Wi-Fi drivers are up to date and your computer supports Wi-Fi direct.
2. If the problem persists even after updating and installing proper drivers, then it is recommended to try out another Adapter. I would recommend the Microsoft Wireless Display Adapter. Due to a lot of manufacturers and available variety of products, there could be any compatibility issues.
3. Make sure you are setting this up on a secure Wi-Fi network. It may not work on an open Wifi network.
4. The last and final step to the solution would be to consult the respective manufacturer and ask for a solid solution to the problem.

This post will help you if Miracast is not working on Windows 10 after an Update.

I hope the post was helpful, and you were able to clearly understand the concept, and use Miracast on Windows 11/10. Once you had set up ready, you can your favorite game on a stable stream. The same Miracast device can also be used with Android devices using the screen share option.

Does Windows 10 support Miracast?

Yes, Windows 10 does support Miracast. Windows 10 has the ability to mirror your screen to any dongle or device (ex, streaming box, TV) compatible with the popular Miracast standard since its launch in 2015. You can also allow your PC to become the wireless display, receiving Miracast signals from a phone, tablet, or other Windows 10 laptop or desktop.

How do I fix Miracast not supported on Windows 10?

Ensure that your device is Miracast-compatible. See that Wi-Fi is enabled on both devices. If that does not fix it, check if Wireless Mode Selection is set to Auto. Few more fixes would be to Enable Intel Integrated Graphics and Reinstall the Wireless Network Adapter driver.

Fix for: Your PC or mobile device doesn’t support Miracast, so it can’t project wirelessly.
