entranceWidi is not installed. How to display an image from a laptop, smartphone, or tablet to a TV over Wi-Fi? TV as a wireless monitor
Intel WiDi is a driver responsible for the operation of the technology of the same name. It, in turn, serves to broadcast content from the memory of a computer or laptop to a TV screen or monitor that supports Intel Wireless Display. The application also allows you to display a "picture" on the screen of some portable Android devices... We draw your attention to the fact that in fresh versions operating system from Microsfoft - Windows 7, Windows 8 and 10, this technology has been superseded by another software solution- which is installed on the system by default.
Appointment
Intel WiDi eliminates the need for external storage to organize the playback of a movie or presentation on a TV and projector. Also, this technology saves you from using VGA and HDMI cables because the image is transmitted through a dot Wi-Fi access... In general, by downloading and installing this driver you will greatly simplify the transfer of data to remote device.
The concept of Wireless Display is a bit like DLNA technology. The key difference from the second is that deploying a DLNA server on a computer allows you to broadcast only separate files, while Intel WiDi provides the ability to turn a remote output device into a "second monitor". Simply put, use this technology much more appropriate for presentations.
Requirements
The main condition for the correct operation of Wireless Display is the presence of a built-in or connected WiDi adapter in the output device. In addition, both devices must be connected to a single wireless access point. Well, the last fact that needs to be taken into account is that the technology does not work with any CPU. Moreover, compatibility problems arise precisely with new processor models.
Key features
- Broadcasting an image from a PC / laptop to a compatible projector, TV or Android device;
- works through a single Wi-Fi access point;
- quick installation and customization;
- high quality the broadcast image;
- compatibility issues with newer CPU models.
Finally, I figured out the wireless display function in Windows 10. I connected and tested everything for half a day to prepare an article for you with verified information. And of course with photos and screenshots.
There are two main technologies: and Intel WiDi (Intel stopped developing this technology), with which you can output image and sound from a computer, laptop or mobile devices via Wi-Fi. Simply put, use a TV (projector, monitor) like a wireless display. The trick is that with the help of these technologies it is possible not only to display a film or photo on the screen "over the air" (as is the case with), but to 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 was connected via an HDMI cable. You can duplicate an image, expand your screen, and more, all wirelessly. There are also monitors with Miracast support.
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 the Intel website), they have discontinued development and support for Intel® WiDi technology. And they report that Windows 8.1 and Windows 10 already initially have support for Miracast, which can be used to connect wireless displays without additional programs.
For everything to work, there must be support for Miracast 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. Also, the video adapter should have such support.
I tested on such equipment:
- PC with processor Intel Core i3-6098P and GeForce graphics GTX 750Ti. Wi-Fi adapter TP-Link TL-WN725N V2.
- Laptop with old Intel processor 3rd generation Core i3 and integrated Intel HD Graphics 4000 video. NVIDIA GeForce GT 635M. Wi-Fi adapter the same TP-Link TL-WN725N V2. Since it does not work through the adapter built into the laptop.
- I used an LG TV as a wireless display. The model is still 2012, but with support for Miracast and Intel WiDi. As it turned 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 directly without a router. 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 in Windows 10 and how to connect to a wireless display. Then, consider the solutions possible problems and mistakes.
Connecting to a wireless display (TV) in Windows 10 via Miracast
Press the keyboard shortcut Win + P(English). A window with different options for displaying the image should appear on the right. And there should be a "Connect to a wireless display" item. 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 check.
The search starts for wireless displays and audio devices.
Most likely, you need to enable the Miracast / Intel WiDi function on the TV. In older LG models, this is done in the menu under "Network". Like this:
On newer LG models, these settings are likely to look different. On Samsung TVs, in the source selection menu, select "Screen Mirroring" (maybe not on all models)... On TV from Sony - "Screen mirroring" in signal sources (separate button on the remote control)... On Philips TVs: under "Settings" - "Network Settings" - "Wi-Fi Miracast". But on mine, which with 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 plugs into the HDMI port of the TV. Receives picture and sound and outputs it to TV.
The TV should appear in the search results. Just select it and the connection process will go.
There will be an inscription "Follow the instructions on the device screen." In my case, on the TV, you need to confirm the connection of the computer.
All is ready!
If you failed to connect the first time, don't give up. Try again. Reboot your devices. The first time, something didn't work out for me either.
You can change the projection mode. For example, expand screens, or use only the second (TV that is connected by Miracast)... Or duplicate the image on both screens.
You can also disconnect from the wireless display there.
Connection by adding a new device in the parameters
There is one more way. In the options, go to the "Devices" section and select "Add Bluetooth or other device". Then click on "Wireless Display or Dock".
Turn on Mirakast on your TV and it should appear on the list. We choose our TV and establish a connection.
Maybe this method is more suitable for someone.
Audio control when connected via Miracast
As well as via HDMI cable, sound is also transmitted via Miracast. At me, right after connection, the sound from the computer was output through the TV speakers. The default was the "Digital Output" device. And this is not always convenient. Therefore, in order for the sound of the playback device through laptop speakers, or speakers, you just need to change the default playback device.
After that, the sound will be played through the computer speakers. If necessary, you can make "Digital Output" the default device back.
Miracast does not work and there is no "Connect to a wireless display" item
In older versions of Windows 10, when the system "realized" that there was no Miracast support, the message "PC or mobile device does not support Miracast, so wireless projection from it is not possible" was displayed.
In newer versions, there is simply no "Connect to a wireless display" item in the "Project" menu, which opens with the Win + P keyboard shortcut.
Most likely, there is no Miracast support at the Wi-Fi adapter level. Here I have, for example, through the built-in in laptop wifi the module cannot connect to a wireless display. The laptop, however, is not new. Somewhere in 2012-13. And then Wi-Fi connections TP-Link adapter TL-WN725N V2 everything works.
To this function worked, you need support on the side of the Wi-Fi adapter and graphics adapter(video cards). Both at the hardware level and at the driver level. It's 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 the test with another Wi-Fi adapter:
And with this configuration, everything works fine.
What can be done:
- Refresh wifi driver adapter. Unlikely, but it will suddenly work. Here is the instruction:.
- 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. Everything works on TP-Link TL-WN725N of the second hardware version (V2). But I'm sure there are a large number of other adapters with Miracast support out there. Need to find.
- Perhaps it will be easier for you.
Let's consider one more problem.
Failed to connect to wireless display
The computer finds the TV, select it, the connection takes a long time and the error "Failed to connect" appears. Or the computer does not see the TV and it does not appear in the list available devices.
I also got this error several times. It is difficult to say what this is connected with. Be sure to try connecting again.
- Restart your computer and unplug the TV for a couple of minutes.
- Perhaps this is due to a bad signal. If possible, reduce the distance between the computer and the TV. Check if Miracast function is active (or something like that) on the TV.
- Update the Wi-Fi adapter driver. I gave a link to the instruction above.
- If possible, try connecting to another TV that can also function as a wireless display.
Update: Eugene shared a solution in the comments, which, as it turned out, helped not only him. The problem was as follows: 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 the device manager helped. I don’t know how correct this decision is, because we are essentially disabling the high-performance video adapter. But it looks like it works. You can try. We go to the device manager and turn off the discrete video card, leaving the integrated one to work.
Do not forget to turn it back on later. When you stop using the wireless display, or it turns out that this solution did not work in your case.
Update: disable antivirus and firewall
There have already been several comments that Miracast in Windows 10 started working after disabling antivirus or firewall.
Try disabling the antivirus you have installed for a while. You can also try disabling the firewall windows defender... If you know what rule in the firewall settings blocks the operation of the 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. Hopefully not in vain. If you have something to add, or want to ask a question, then I'm waiting for you in the comments. Good luck!
But the cable is not always convenient to lay, thanks to the cable you are "tied" to the place and cannot move freely. There are technologies that will allow you to wirelessly display the screen of a laptop, netbook or tablet on a TV, one of these technologies is WiDi.
WiDi (Intel Wireless Display)- wireless transfer of content from a mobile device (laptop, ultrabook, tablet) to a TV (Smart TV), developed by Intel. The technology is based on Wi-Fi standard... (Wikipedia).
In order to be able to connect your TV to a laptop / ultrabook / tablet using WiDi, it is necessary that each of the devices support this technology. No additional equipment (routers, routers, access points, etc.) is needed.
In order to understand whether your WiDi TV supports or not, you need to read its technical capabilities, it's easier to do all this by going to the TV manufacturer's website, find your model and get acquainted with the technical characteristics.
To understand whether your laptop / ultrabook or tablet supports WiDi technology, it is necessary that it meet the requirements for WiDi , namely:
| Conditions | Intel® WiDi | Intel® Pro WiDi |
| Operating system | Windows 7, Windows 8 / 8.1 (Windows 10) | |
| CPU | - 2,3,4,5 generation Intel® Core ™ i3 / i5 / i7 |
4th Generation Intel® Core ™ Mobile and Desktop Processors with Intel® vPro Technology |
| Graphics | Intel® Iris ™ Graphics 5100 Intel® HD Graphics 5000, 4600, 4400, 4200, 4000, 3000 (mobile), 2500, 2000 (mobile) |
Intel® Iris ™ Pro Graphics 5200 Intel® Iris ™ Graphics 5100 Intel® HD Graphics 5500, 5000, 4600, 4400 |
| Wifi cards |
Centrino® Wireless-N 1000, 1030, 2200,2230 BCM43228 |
Intel® Dual Band Wireless-AC 3160 Intel® Dual Band Wireless-AC 7260 Intel® Dual Band Wireless-N 7260 Intel® Dual Band Wireless-AC 7265 Intel® Dual Band Wireless-N 7265 |
In order to see what processor, wireless adapter and graphics you are using, I recommend reading the article -.
If your mobile device meets the requirements and the TV supports WiDi, you can establish a WiDi connection.
Turn on WiDi on the TV.
In this example, a TV will be used. Lg with WebOs, enabling this feature on other TVs ( Samsung, Philips, Sony, Toshiba etc.) will proceed by analogy.
Open the Smart Apps menu, to do this:
On a standard remote, press the "Smart" button.
On the Magic Remote, press the "Home" button
Then open the full application menu.
Select "Screen Share".
Thus, you have turned on the WiDi function on the TV.
Enabling WiDi on a laptop, ultrabook, tablet.
In order to use WiDi technology on a laptop, ultrabook, tablet, you need to install the appropriate software. This requires download the program for WiDi .
For Intel WiDi download Software Intel® Wireless Display for Windows, for Intel Pro WiDi - Intel® Pro WiDi for Windows.
Installing the software for WiDi is extremely simple and boils down to clicking the "Next" button and agreeing to the license agreement.
After installation, a shortcut will appear on the desktop Intel (R) WiDi.
Launch the Intel (R) WiDi application. When turned on, it automatically scans for the presence of wireless displays and, upon finding it, will offer to connect.
After the connection is agreed, numbers will appear on the TV, which must be entered on a laptop, ultrabook, tablet in the Intel WiDi program. Then the connection will be made within a few seconds. As a result, everything that you see on the screen of the mobile device will be displayed on the TV.
In addition to mirroring the image, the TV can be used as a second screen. To do this, press the "Win" + "P" key and select "Extend" (suitable for Windows8 / 8.1, for Windows 7 follow the steps described below). Thanks to WiDi technology, your TV becomes a full-fledged monitor, you can change the resolution, screen orientation, etc. on it. To do this, right-click on the desktop, select " Screen resolution"or go "Control Panel" - "Screen" - "Screen Resolution Setting".
In the window that opens, you can change the screen resolution, both on a laptop, ultrabook and on a TV, choose to expand or duplicate the image, change the screen orientation.
To disable the WiDi connection, in the Intel WiDi application on the corresponding wireless display, click "Disable".
Overall impression of WiDi.
WiDi is a great way to get rid of some of the wires in an apartment / house, in addition to wireless connection displaying a screen from a laptop, ultrabook, tablet on a TV, it can act as a second monitor, which allows several people to use one laptop, ultrabook at once. For example, by expanding the screen, you can turn on a movie / presentation / photo on the TV, and at this time on a laptop, ultrabook, surf the Internet, play a game, etc.
But this method of wireless connection has drawbacks, since this Intel development, it has firmly connected this technology with its products and this technology can be used only on a limited number of laptops, ultrabooks and tablets. WiDi is also not suitable for demanding games, since the processing power is relatively scarce, plus there is a noticeable delay in displaying video on a mobile device and TV. It is a fraction of a second and will not prevent you from watching videos, photos, presentations, but it is critical for action games where instant reaction is required.
In my opinion, WiDi technology is a very good solution for a wireless connection, and it is ideal for most tasks.
Pros of using WiDi:
1 Allows you to wirelessly connect mobile devices to the TV;
2 Supports a high resolution FullHD (4K support coming soon) + 5.1 sound;
3 It is possible to expand the screen (use the TV as a second monitor).
Cons of using WiDi:
1 Not every device supports WiDi technology (applies to both laptops, ultrabooks, tablets and TVs);
2 Delay in a split second on the TV screen.
Video of connecting laptop to TV using WiDi.
I have long dreamed of building a computer that would not use wires to communicate with peripheral devices. That is, to put system unit in one room, connecting it only to the mains, and placing the entire periphery - a mouse, keyboard, monitor, speakers - in another room at the workplace. Wireless keyboard and mouse have long been a surprise. But transferring an image to a monitor without using a wire seems to be a non-trivial task. It is to this problem that this article is devoted.
Intel currently offers WiDi (Wireless Display) technology for transferring images from a laptop, tablet, phone to a monitor. I was interested in the question of how to connect WiDi to a stationary computer.
Requirements for connecting WiDi on a stationary computer.
- Wireless display adapter. Needed if your TV or monitor does not support WiDi. Currently, only the most expensive models of monitors and TVs support this technology. See the list of WiDi-enabled devices on the Intel website.
- 3rd or 4th generation Intel i3, i5, i7 processor.
- WiDi compatible network card.
- Operating system Microsoft Windows 7 and newer.
- Intel software. Not necessary for Windows 10, as Windows 10 has built-in software displaying images on a wireless monitor.
Out of all this, I was missing a wireless display adapter and network card with WiDi support. I couldn't find where to buy these things in Russia, so I ordered them on Amazon.com. Ordered NETGEAR Push2TV 3000 and Intel Centrino Advanced-N 6205 for Desktop NIC.
Connection and configuration.
Installing Intel Centrino Advanced-N 6205 for Desktop is straightforward. You just need to insert the network card into the PCI-E slot, take it from the enclosed disk, or download and install the driver.
Configuring NETGEAR Push2TV 3000.
- Download the latest firmware from the Push2TV Adapter for Wireless Display page. On this page, you must click the link with the word Firmware.
- Connect the adapter to the mains.
- Press the button on the end of the device and hold it for 7 seconds, as a result a white light on the adapter should blink. On your computer, a network named Push2TV should appear in the list of wireless networks.
- Connect to wireless network Push2TV.
- Open the page with the address 192.168.3.1 in the browser.
- In the "Firmware Update" section of this page, specify the file downloaded in the first step and click the "Upload" button.
As a result, NETGEAR Push2TV 3000 software will be updated to latest version... To complete the configuration of the adapter, it remains to connect it to a monitor or TV HDMI wire ohm. I would like to note that the set with NETGEAR Push2TV 3000 does not include an HDMI cable, so you need to purchase it separately.
Setting up the software on the computer
As I wrote above in Windows 10 there is a Projector function that allows you to connect to a WiDi display without third-party software, if you have a network card that can work with WiDi. To connect to the projector you need:
- Press the Win + P keys.
- A panel will open on the right, you can select the "Connect to a wireless display" item. If the WiDi adapter is turned on, the computer will detect it and you can try to connect.
If you are using the old version - Windows 8.1 and older, then the instructions below are for you.
- Download Intel® Wireless Display Software for Windows»From the Intel WiDi Software page.
- Install Intel® Wireless Display Software for Windows. An Intel WiDi shortcut appears on the desktop.
- Launch Intel® Wireless Display Software for Windows.
- A window should open in which after a while the adapter should appear. Here you just need to click the connect button.
- At the moment of the first connection to a wireless monitor, the Intel WiDi program will ask for a password, which will be displayed on the wireless monitor itself. On subsequent connections, it will not be required. You can also check the "Automatic connection" checkbox, then when the Intel WiDi program starts and the WiDi adapter is detected, the program will connect to the monitor automatically.
That's all about how to connect WiDi on a stationary computer.
Impressions
I will say right away that I immediately refused to use this technology on my PC, this technology will be interesting when used with smartphones or tablets, or in the case when it is necessary to connect a TV and a computer at a considerable distance, but not for normal conditions that use a computer. So what I didn't like:
- Unlike wireless mouse and keyboards that work fine in UEFI and BIOS, WiDi only works when running application Intel WiDi, respectively, Windows must be running, and the user is logged in. This problem can be solved by automatic start Intel WiDi applications and setting the "Automatic connection" checkbox.
- The image quality is worse than when connected via a wire, this is especially noticeable if you open a page with text. It is quite possible to watch films.
- The NETGEAR Push2TV 3000 adapter, when transmitting an image to the monitor, creates a ridiculous and large mouse pointer that moves somehow woodenly and, moreover, does not change its shape when the situation requires it, that is, it is always in the form of an arrow.
- For some reason, the image on a 27-inch monitor filled only 90% of the screen, and there is a black border around the edges.
- Occasionally flashing interference. They do not interfere too much, but they do not add joy either.
Thus, I can assure you that it is too early to use a wireless monitor on a desktop. I have no doubt that the times will come when wires for connecting the monitor with the system unit will not be needed, but so far those times have not come.
Hello blog readers!
Today on the blog there will be such a post, which is called "two in one". I will answer the reader's question and tell you about another entertaining and convenient technology with which you can organize the transfer of a picture from a monitor display of one device to another - for example, from a computer to Windows to a phone, TV or projector. It is called Intel WiFi Display or Wireless Display - WiDi.
Actually, here's the question:
Greetings.
Transmission from the Laptop via WiFi channel, Online Display mode, reception is carried out on the Device, which clings to the TV on the HDMI connector.
How to set up WiFi Display, Samsung laptop on Windows 7?
I think that the history of the emergence and development of WiDi will be boring to read - that's not why you came here, right? Therefore, as usual, let's go straight to practice.
Conditions for WiDi operation
So, devices equipped with WiDi have the ability to detect each other and exchange data. However, there are a number of conditions that they must meet in order to use this technology. If you plan to use a phone in such a bundle, then it must be equipped with an operating Android system version not lower than 4.2 and a special chip from RockChip (RTL8188EUS, Broadcom BCM43362, BCM4330, APXX). In addition to phones, Intel WiDi is supported by many TVs, projectors and media players, which also have an integrated Intel Centrino chipset that supports Intel My Wi-Fi. If this function is not in the device, then it does not matter - there are separate devices like WiFi adapters- WiDi adapters, which are connected to TV via HDMI and receive wirelessly picture and sound from a smartphone or tablet.
If you remember, I already talked about a very similar technology -. In my video tutorial, with its help, we also played films stored on the computer on the TV. But there is also a difference - in DLNA we could only play files. In WiDi, we have a full-fledged second monitor, which significantly expands the possibilities of use, for example, for playing Androd games on a large television screen. One of the varieties of this technology is, which we will talk about in a separate article.
Intel Wireless Display for Windows
But that's not all. Intel Wifi Display can also work on a computer with an operating Windows system 10, 8 or 7, equipped with a modern Intel processor - Core i3, Core i5, Core i7 - with one of the WiFi adapters:
As you understand, the use of this adapter built into the processor is possible only if the built-in video core of the processor is working. If your computer has a separate video card and the video core of the Intel processor is turned off, then the scheme will not work.
Also, WiDi only works with Windows 7 or higher, so XP lovers will not be able to see WiFi in action either.
How do I set up Intel Widi?
Let's summarize - to configure WiDi we need 2 devices - a source and a receiver. They can be:
- TV with built-in WiDI chip or external adapter
- Windows PC or laptop with Intel processor and Wireless Display support
- Smartphone with RockChip chip and Android 4.2+
If all of this is available, then let's customize. As a receiver we will use big screen regular TV... We turn it on, connect it to an external one via HDMi and select it as a source for the picture. An image like this will appear (in this example, using a Netgear adapter), which indicates that the device is ready to connect to a signal source:
To broadcast video from a computer, you need to download the Intel Wireless Display program for your operating system and run it.
After its launch, a window will open with a list of devices with a working adapter that are in the receiving range. We choose our TV.
We enter it on the PC when connected and after a few seconds we get a duplicate of the computer desktop screen on the TV monitor.
Intel WiDi via smartphone
Video is played in the same way from a smartphone based on Android. First, using the same scheme, turn on the adapter on the TV, after which we go to the Android menu in the Settings menu and look for the Wireless projector (or screen) item. If it is not there, then your phone does not support WiDi and you will not be able to connect.
After a few seconds, the image from the phone display will appear on the monitor. If you have activated the vertical mode, then it will be displayed incorrectly, therefore, in advance, put your smartphone in the mode horizontal orientation screen.
As you can see, the technology is very viable and significantly expands the possibilities of using a smartphone or laptop as a full-fledged media center. Unfortunately, today the only but significant limitation is the requirement for hardware - only certain chipsets can work with it, wireless adapters and processors. However, in the future, I think, Wireless Display will become the same generally accepted data transfer standard as the same DLNA.
