Miracast technology was developed by Microsoft engineers. It is designed to transfer data from smartphones, tablets or computers to the display without the use of cables. In the new version of the OS, this function has become especially popular, so to get a clear picture on the screen and for freedom of movement, you need to know how to turn on Miracast Windows 10.
What it is?
The Miracast standard ensures interconnection between gadgets. They connect and transmit information to each other using a wireless network, without using an HDMI cable.
Advantages
- The main advantage is the absence of a rigid connection between the device and the display on which the image is broadcast using a cable. This connection method is modern and more convenient.
- This is a multi-platform technology that provides connection to devices running on different OSes, which distinguishes Miracast from similar technologies from Apple and Google.
- There is no loss of quality when transmitting data, so it fully replaces the HDMI cable.
Flaws
- Microsoft's streaming technology needs improvement because it only displays what's shown on the gadget's screen. Analogues have wider functionality.
- Frequent malfunctions make the function unpopular. Miracast is an open standard, so devices certified with this technology should work flawlessly with each other. But in practice there are failures.
Enabling on Windows 10
To create a connection between two gadgets using this technology, they must have a Wi-Fi adapter, and one of them must have Windows 8.1 or higher installed.
Good to know! Older TV models may not support Miracast. This problem can be solved by updating its firmware or purchasing a special adapter.
Disabling the receiver is done in the same section of the Settings application.
Select the receiver → Remove device → confirm the action.
Watch the video to see how to connect your smartphone to your TV using this feature.
Conclusion
In the near future, Miracast will become an excellent alternative to HDMI cables, because this method is much more convenient. The function is configured in the Windows 10 Settings application. In this case, the TV and computer must support this technology and have a Wi-Fi adapter.
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 has 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 an 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 have stopped developing and supporting Intel® WiDi technology. 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 Core i3-6098P processor and GeForce GTX 750Ti graphics card. Wi-Fi adapter TP-Link TL-WN725N V2.
- A laptop with an old third-generation Intel Core i3 processor and built-in Intel HD Graphics 4000 video. NVIDIA GeForce GT 635M video card. 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, we will consider solutions to 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 displays it on 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 versions of Windows 10, when the system "understood" that Miracast was not supported, it displayed the message "The PC or mobile device does not support Miracast, so wireless projection from it is not possible."
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. For example, I have no way to connect to a wireless display through the Wi-Fi module built into my laptop. The laptop, however, is not new. Somewhere around 2012-13. And after connecting the TP-Link TL-WN725N V2 Wi-Fi adapter, everything works.
For this function to work, you need support on the side of the Wi-Fi adapter and graphics adapter (video card). Both at the hardware and driver level. This is easy to check.
Launch Command Prompt 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. The graphics driver supports it, 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 the Wi-Fi adapter driver. 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 consider 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 blinked 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!
Many owners of modern gadgets have probably heard about Miracast technology, which allows you to transmit multimedia signals 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 running Windows 10 provide the ability to project images from their screen onto another display, for example, an image 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 desired function, you need to go to its network settings and make sure that the Wi-Fi Direct option is 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 - Screen Sharing - 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
You can transfer a picture from a Windows 10 device not only to a TV, but also to another device running Dozens. 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
Android devices also mostly support Miracast technology, but some budget models may not have this feature. To make sure you have the functionality you need, look for the “Cast” item in the settings or on the home screen’s quick access panel (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 Wi-Fi network settings. 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.
Once 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 a Windows 10 laptop and a 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 the software; you probably just need to install the latest version of the 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.
In Windows 10 you can find one very interesting feature called Miracast, which can transmit image and sound via wireless technologies, in other words via Wi-Fi. Thus, if you want to watch a movie on a large TV and monitor, connect Miracast.
This guide is precisely aimed at helping users master the wonderful technology of wireless data transmission. I will show everything with an example. Let's also look at some connection problems.
How to connect a TV or monitor via Miracast?
First, make sure that your TV or monitor supports a wireless network (Wi-Fi), and now let's get down to business.
On your Windows 10 computer, hold down the keyboard shortcut Win+P and the “Project” section on the right immediately opens. At the very bottom we find the item "Connect to a wireless display" and click on it.
The search for wireless devices to which we will transmit the picture, in other words, a TV, monitor or something else, will immediately begin.
If something was found, click on this device; by the way, if the TV/monitor screen is turned off, be sure to turn it on.
What do we get? And we receive an image from the computer monitor, which is projected onto the TV screen, and the image will be transmitted in good quality and without interference.
What to do if Miracast doesn't work?
As you can see, we performed a minimum of steps and the connection took us less than five minutes. But, as always, there may be some problems and here, by the way, are what they are.
No Miracast support
In other words, your Wi-Fi adapter simply does not support Miracast, or the necessary drivers are not installed for the adapter. This is relevant if you do not have the “Connect to a wireless display” option.
If the item is still there, then when you click on it you may see a message telling us that the device does not support Miracast. Therefore, for many, this article may be useless. Of course, you can purchase another Wi-Fi adapter that supports this technology.
If there are no Windows 10 drivers for your devices, don't despair. Download what data, for example, may be available for Windows 8, they may also be suitable.
Useful:
Connecting to a TV or monitor via Miracast takes a very long time
This is also a very common reason that is familiar to us when connecting any other device to a Wi-Fi network - the connection continues endlessly.
Just above, I described that you need to install the latest versions of drivers on the Wi-Fi adapter and hope that the system has already installed them automatically. This method can also work here, but not always.
There are few versions here, perhaps the problem is with the TV itself, because some devices can connect immediately, but some cannot, or the technology is not supported by the external device. You can try restarting both the TV and the computer, it may help, and you should also take into account that old equipment can greatly ruin your life, that is, it will be possible to transfer the image to the TV or monitor, but there will be terrible brakes on both devices.
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
The technology is used to wirelessly transfer pictures from a computer to a TV. You can use this technology even if you don't download the program. The program is natively built into Windows 10, as it works over WiFi and is free. You need to do 2 important things:- Find out if your Windows 10 computer supports Miracast technology;
- Find out about support for this technology by a third-party device;
To transfer a picture over the air, you can use the hotkeys WIN+P. After this, a window will open in front of you in which you can choose how exactly you want to transfer the picture. For example, by cable or by air. Next, if you select the wireless option, the Miracast window will open in front of you. For the technology to work correctly, you must have installed
