Add a wireless display windows 10. Enable and configure Miracast

You want to download the Miracast program for Windows 10 the moment you think about transferring a picture from your computer to your TV. But you don’t need to download anything, since the technology is initially built into the system and you can easily transfer the image to other devices. The main thing is that your device has the appropriate components. Of course, the appropriate components must also be on the device where you want to transfer the image. You can transfer the image, for example, to a projector or TV.

Possibilities for wirelessly transmitting pictures to a TV

• Find out if your Windows 10 computer supports Miracast technology;
• Find out about support for this technology by a third-party device;

Many owners of modern gadgets have probably heard about Miracast technology, allowing you to transmit a multimedia signal between devices wirelessly. This standard provides for the connection of the receiver and transmitter via Wi-Fi Direct, i.e. directly, without using an intermediate link, which is usually a router. We will not talk in detail about what Miracast is and how this technology works, but rather we will immediately try it in practice.

How to enable Miracast in Windows 10 and transfer the image to your TV

Almost all devices are Windows control 10 provide the ability to project an image from your screen onto another display, for example, a picture from a laptop or tablet can be transferred to a TV. Of course, the TV (or other receiver) must support such technology. In order to find out whether your TV has the required function, you need to go to its network settings and make sure there is a Wi-Fi Direct option there.

So, let's try using Miracast to connect a laptop with Windows 10 to an LG TV running webOS. Pairing is done through the Connection Manager. Let's find it on the TV in the Smart TV section, launch it and follow the path sequentially Personal Computer – General access to screen – Miracast.

On the right, click on the “Start” button. The TV is now ready to connect wirelessly.

Click on its name to initiate the connection.

If everything went well, the laptop desktop will appear on the TV screen.

Connecting two Windows 10 devices via Miracast

Send an image from Windows devices 10 can be used not only on a TV, but also on another device running “tens”. For example, you can duplicate the display of a tablet on a laptop screen. True, the receiver must first be configured. To do this we go to Settings - System - Project to This Computer. If your PC supports projection, you will see a corresponding message.

Next there will be a list of settings with which you need to set the display visibility parameters. Having enabled projection, let's try to establish a connection. On the sending device, click “Connect to a wireless display”, and then select the display. If the devices are compatible, the screen will be duplicated.

How to project an Android phone screen via Miracast

Devices on Android based Most also support Miracast technology, but some budget models may not have this feature. To make sure that the required functionality is available, find it in the settings or on the panel quick access home screen“Broadcast” item (other names are “Wireless display” or “Share screen”).

But before you start broadcasting, you need to enable the Wi-Fi Direct option on both your TV and smartphone. Let's go to TV Settings – Network – Wi-Fi Direct, and then press the “Off” button.

On your phone, Wi-Fi Direct is enabled in the settings. Wi-Fi networks. After activating Wi-Fi Direct on your Android mobile device, select a signal receiver and connect to it.

The TV should prompt you to connect, requiring confirmation.

Now open the Connection Manager, and then follow the path Smartphone - Screen Sharing - Miracast. Click the “Start” button.

On your phone, click on the “Broadcast” icon and select the wireless display.

After the connection is established, the same picture will appear on the TV screen as on the mobile device.

Connection problems

When trying to establish a connection between laptop computer With Windows 10 and the signal receiver via Miracast, various types of failures often occur. One of the most common problems is that the transmitting device cannot find the wireless display. The reason for this kind of malfunction most likely lies in the fact that Miracast technology is not supported by the receiver (TV, laptop). You can also try updating software probably just needs to be installed latest version software

If the display is still detected, but an error occurs during the connection, then either the devices are incompatible with each other at the hardware level, or old drivers are installed on the transmitter. There are other possible reasons.

Since the Miracast standard is relatively young, problems arise quite often, even if the equipment seems to be completely new and the technology is supported for it. In any case, if an attempt to connect devices over the air fails, there is always an alternative in the form of a more reliable and stable one.

Miracast is a technology that “streams” content using a wireless network. New Windows OS users can use this feature without additional settings. Use Miracast to stream videos, photos and music from your computer to third-party devices that support this technology.

Miracast transmits the “picture” from the computer screen to third-party devices using a wireless network, that is, without additional cables.

Smart TVs, mobile devices, projectors and other devices can receive broadcast content. To broadcast via Miracast, you do not need digital signal cables HDMI, VGA and others.

All data is “transmitted” wirelessly Wi-Fi technology. For a full “broadcast” of multimedia mobile device and the TV (other screen) must be connected to the network. Both devices (“transmitter” and “receiver”) are synchronized at one access point.

Using Miracast on Windows 10

This section displays everything peripherals that are connected to the computer. You need to create a connection to a new device to which information will be transferred. By clicking on the “+” key, which is located next to the “Add Bluetooth or other device” tab, select the “Wireless display or docking stations” section.

Then wait until OS Windows using automatic search, will detect available devices that are connected to the router. The broadcast of “content” will begin immediately if there is a device with this technology on the “network”. To transmit information, click “start broadcast”.

Flaws

Because of this, you will not be able to fully play. Watching movies, photos and listening to music - no problem. The “picture” delay appears for two reasons: low throughput"receiver", possibly "transmitter" or unstable wireless network.

Key Features

• the technology is integrated into the new OS Windows;
• allows you to “transfer” the image to Miracast-enabled devices;
• connects devices via Wi-Fi;
• works without installing third-party software;
• During the broadcast, you will encounter a high response of the transmitted “picture”.

Miracast is a technology that was developed by Microsoft for wirelessly transmitting images and sound to the display of a TV and other gadgets. This feature is available for all devices that have an appropriate Wi-Fi adapter. This article will describe the process of enabling Miracast in Windows 10, as well as solving some problems associated with its operation.

Wireless Miracast technology provides accurate image transmission without the need for an HDMI cable to various devices, which support such a function. Disadvantages include unfinished functionality and rare crashes.

Method 1: Keyboard shortcut

Setting up and running Wi-Fi Direct using a keyboard shortcut can take just a few minutes. This process is a bit similar to connecting a computer to another device via Bluetooth.

Now you can enjoy high-quality picture and sound on another device without the need for cables.

Method 2: System “Options”

You can also connect everything via "Options" systems. This method differs from the first only in its implementation, but you get a similar result.

That's how easy it is to add a device via "Options" and use the capabilities of Miracast.

Solving some problems

Enabling Miracast in Windows 10 is quite easy, so you shouldn't have any difficulties. In addition, this technology is supported by most modern devices, which makes image and sound transmission much easier.

I finally figured out the wireless display feature in Windows 10. I spent half a day connecting and checking everything to prepare an article with verified information for you. And of course with photos and screenshots.

There are two main technologies: and Intel WiDi (Intel company stopped developing this technology), with which you can display image and sound from a computer, laptop or mobile devices via Wi-Fi. In other words, use the TV (projector, monitor) like a wireless display. The trick is that with the help of these technologies you can not just display a movie or photo on the screen “over the air” (as is the case with), but broadcast everything that happens on the main computer monitor or laptop screen.

A wireless display, which is most often a TV, works as if it were connected via HDMI cable. You can duplicate the image, expand the screen, etc. And all this wirelessly. There are also monitors that support Miracast.

The Wireless Display feature in Windows 10 displays images using Miracast technology. But, for some reason, when connected, the TV had the inscription “Intel’s WiDi.” As it turned out (read on Intel website), they stopped development and support Intel technologies® WiDi. And they report that Windows 8.1 and Windows 10 already have support for Miracast out of the box, which can be used to connect wireless displays without additional programs.

For everything to work, there must be Miracast support at the hardware and driver level. The Wi-Fi adapter that is built into your laptop or connected to your PC must support the wireless display function. The video adapter should also have such support.

I tested on the following equipment:

• PC with Intel processor Core i3-6098P and video card GeForce GTX 750Ti. Wi-Fi adapter TP-Link TL-WN725N V2.
• Laptop with old processor Intel Core i3 third generation and integrated video Intel HD Graphics 4000. Video card NVIDIA GeForce GT 635M. Wi-Fi adapter is the same TP-Link TL-WN725N V2. Because the adapter built into the laptop does not work.
• I used an LG TV as a wireless display. The model is still 2012, but with support for Miracast and Intel WiDi. As it turns out, the new and sophisticated Philips TV does not have built-in support for Miracast. If your TV also does not support this technology, then you can use.

This connection works without a router, directly. There is no need to connect your computer (laptop) and TV to the same router.

In this article, I will first show you how to enable Miracast on Windows 10 and how to connect to a wireless display. Then, let's look at solutions possible problems and errors.

Connecting to a wireless display (TV) in Windows 10 via Miracast

Press the keyboard shortcut Win+P(English) . A window should appear on the right with different options for displaying the image. And there should be an item "Connect to a wireless display". Click on it. If there is no such item, then most likely your hardware or driver does not support this function. At the end of the article I will write about this in more detail and show you how to perform the check.

It will begin searching for wireless displays and audio devices.

Most likely, you need to enable Miracast/Intel WiDi on your TV. In older LG models, this is done in the menu, in the "Network" section. Like this:

On new LG models, these settings most likely look different. On Samsung TVs, in the signal source selection menu you need to select "Screen Mirroring" (may not be available on all models). On Sony TV - "Screen mirroring" in signal sources (separate button on the remote control). On Philips TVs: in the "Settings" section - "Network settings" - "Wi-Fi Miracast". But on mine, which has Android TV, there is no such item.

If your TV does not have built-in Miracast support, you can buy a separate Miracast (Mirascreen) adapter. It connects to the HDMI port of the TV. Receives image and sound and outputs it to the TV.

The TV should appear in the search results. Just select it and the connection process will begin.

It will say "Follow the instructions on the device screen." In my case, you need to confirm the computer connection on the TV.

All is ready!

If you fail to connect the first time, don’t give up. Try again. Reboot your devices. Something didn’t work out for me the first time either.

You can change the projection mode. For example, expand the screens, or use only the second (TV connected via Miracast). Or duplicate the image on both screens.

There you can disconnect from the wireless display.

Connection by adding a new device in the settings

There is another way. In Settings, go to the "Devices" section and select "Add a Bluetooth or other device." Then click on "Wireless Display or Dock".

Turn on Miracast on your TV and it should appear in the list. Select your TV and establish a connection.

Maybe this method will be more suitable for someone.

Sound control when connected via Miracast

Just like an HDMI cable, Miracast also transmits sound. For me, immediately after connecting, the sound from the computer was output through the TV speakers. The default device was "Digital Output". And this is not always convenient. Therefore, in order to get the sound from the playback through your laptop speakers or speakers, you just need to change the default playback device.

After this, the sound will be played through the computer speakers. If necessary, you can return "Digital Output" to the default device.

Miracast does not work and there is no "Connect to a wireless display" option

In older Windows versions 10, when the system “understood” that there was no Miracast support, the message “The PC or mobile device does not support Miracast, so wireless projection from it is not possible” was displayed.

In new versions, there is simply no "Connect to a wireless display" item in the "Project" menu, which is opened by the Win + P key combination.

Most likely, there is no Miracast support at the Wi-Fi adapter level. Here I have, for example, through the built-in laptop Wi-Fi The module cannot connect to a wireless display. The laptop, however, is not new. Somewhere around 2012-13. And after connecting the TP-Link TL-WN725N V2 Wi-Fi adapter, everything works.

To this function worked, support is needed on the side of the Wi-Fi adapter and the graphics adapter (video card). Both at the hardware and driver level. This is easy to check.

Run command line and run the command netsh wlan show driver.

The results will contain the line "Wireless display supported:" With the factory (old) Wi-Fi module on the laptop I have the following result:

As you can see, there is no support. Graphics driver supports, but Wi-Fi does not.

And here is the result of testing with another Wi-Fi adapter:

And with this configuration everything works great.

What can be done:

• Update wifi driver adapter. It's unlikely, but it might work. Here are the instructions: .
• If, according to the test results, the problem is only in Wi-Fi, then you can replace the Wi-Fi adapter itself. But I noticed that the specifications simply do not indicate whether there is support for a wireless display or not. On the TP-Link TL-WN725N second hardware version (V2) everything works. But I'm sure there are a large number of other adapters that support Miracast. Need to find.
• It might be easier for you.

Let's look at another problem.

Failed to connect to wireless display

The computer finds the TV, select it, it takes a long time to connect and the error “Failed to connect” appears. Or the computer does not see the TV and it does not appear in the list of available devices.

I also got this error several times. It's difficult to say what this is connected with. Be sure to try connecting again.

• Restart your computer and turn off the TV's power for a couple of minutes.
• This may be due to a bad signal. If possible, reduce the distance between the computer and the TV. Check if Miracast is active (Or something like that) on TV.
• Update the Wi-Fi adapter driver. I provided a link to the instructions above.
• If possible, try connecting to another TV that can also work as a wireless display.

Update: Evgeniy shared a solution in the comments, which, as it turned out, helped not only him. The problem was the following: the computer found the TV, as shown in the instructions above. But when I tried to connect, the screen flashed on the TV and an error appeared: “The connection request from... failed. You can try again from your mobile device.”

Disabling the discrete video card in Device Manager helped. I don’t know to what extent this is the right decision, because we are essentially disabling the high-performance video adapter. But it seems to be working. You can try it. We go to the device manager and disable the discrete video card, leaving the integrated one working.

Don't forget to turn it back on later. When you stop using the wireless display, or it turns out that this solution did not help in your case.

Update: disable antivirus and firewall

There have already been several comments that Miracast in Windows 10 started working after disabling the antivirus or firewall.

Try disabling your installed antivirus for a while. You can also try disabling Windows Defender Firewall. If you know which rule in the firewall settings blocks the operation of a wireless display and how to add it to the exceptions, please write in the comments.

I spent a lot of time and effort on this article. I hope not in vain. If you have anything to add or want to ask a question, I’m waiting for you in the comments. Best wishes!
