Xiaomi wireless display how to set up a laptop. How to set up Xiaomi wireless display. What devices can interact with this technology

Have you ever heard of another device being advertised as supporting "Miracast"? Making its way into the mainstream, Miracast is a killer feature poised to destroy other streaming standards in the highly fragmented Android market.

Acting as a wireless HDMI receiver, Miracast mirrors Android devices onto your TV screen in high definition and with sound. Once Miracast is enabled, everything from the overall interface to apps to video is mirrored on the big screen without a cable connecting the two devices.

Miracast does not rely on your home Wi-Fi network. But it's not magic - let's pop the hood to see how Miracast works.

Under the hood

An experienced Android user will perk up when they hear that Miracast is built on the now much ignored Wi-Fi Direct technology. Wi-Fi Direct, first introduced in Android 4.0, allows the user to create a private network (point-to-point) that allows other users to connect and share files. The technology never went mainstream, but it paved the way for Miracast.

With Wi-Fi Direct as the basis, Miracast doesn't need to rely on your home network. Instead, he creates his own. For example, your TV creates a special network that your phone or tablet then discovers. Once two devices are paired, data can flow freely between them.

When it comes to what you can stream to your TV, the options are endless. Miracast uses the H.264 codec to deliver 1080p video and 5.1 channel audio. Even copyrighted materials such as DVDs and music can be transferred to the TV thanks to the DRM layer.

Wait, is this like a Chromecast?

I'm so glad you asked. No, Miracast is completely different from Chromecast. And that's why.

WITH Miracast, your TV (or Miracast dongle) depends on the Android device the entire time the devices are paired. If your Android falls asleep, your TV screen goes unconscious too. This interdependence is both a great advantage and a tragic pitfall for Miraxt (read battery drain).

Chromecast, however, only relies on the mobile device for a moment during the initial setup. Once the Chromecast receiver knows what content it should play, your mobile device is free of load. In this case, you can freely multitask, lock your device, or queue the next video.

For the same reason, Chromecast isn't nearly as dynamic as Miracast—it only works with compatible video and music apps, and won't play DRM-protected content on your device. What about mirror image? Chromecast mirrors only the Chrome browser (in beta version) and that’s it.

How to use Miracast

To use Miracast, you need two things: a Miracast-compatible Android device and a Miracast TV or Miracast adapter.

The Android part is simple. If your device is running Android 4.2 or later, you most likely have Miracast, also known as the "Wireless Display" feature.

Now you need to set up your Miracast receiver. Although the technology is relatively new, TV manufacturers such as Sony, LG and Panasonic are integrating Miracast into their TVs. But, if you purchased your TV earlier than last year, it most likely does not support Miracast. Instead, you will need a key.

Try looking for Miracast dongles in online stores, for example this one. Most of these dongles cost in the $40 - $60 range, and are really designed to do just one thing: mirror your Android device to your TV.

We tested the Netgear Push2TV dongle (like the one linked above), which was mostly reliable, with the exception of a few stutters and stutters during playback. Overall, it does the job it promises.

After connecting the Miracast dongle, switch the TV to use it. Then take your Android device and go to Settings>Display>Wireless Projector. (As always, the process may vary slightly depending on your device.)

Turn on the wireless projector function and wait until the device detects the Miracast dongle or TV. When it appears in the list, click "Connect" and a few moments later, you will see the Android device duplicated on the big screen.

Now you can play a playlist, watch a 1080p movie, or show your friends how you play angry birds on the big screen. Just remember that while the brightness on your device won't affect your TV, locking Android will dim your TV too.

So, if you are watching a movie, don't forget to connect your Android to the charger.

Verdict.

While Miracast is a great all-in-one solution for displaying Android on the big screen, the technology still has room for growth. The lack of multitasking is the biggest disappointment - capturing your Android device while it is actively generating content for the receiver. Which, however, is already changing. The LG G2, Sony Xperia Z and G Optimus Pro are the first phones to implement Miracast multitasking, which in turn allows you to mirror the screen while doing other work on the phone.

But even with improved compatibility, Miracast needs help. Sometimes video stutters and some difficulty establishing a connection between the Android device and the receiver can turn a pleasant moment into a frustrating one. However, the ability to stream anything from Android to a TV and the convenience of a wireless connection may make Miracast worthy of the attention of major TV and smartphone manufacturers.

The Wireless Display function is designed for data exchange. Its analogues are Bluetooth, WiFi and other services. The developer was Intel Holding. File exchange occurs by synchronizing technology media with each other without a wired connection. It is applicable to smartphones running Android 4.2 and higher.

The function is easy to use. All you have to do is turn it on on your gadgets and create a pairing through “Settings”. The innovation is most widely used for viewing recordings and photos from a gadget on the large screen of a modern TV.

Widi Xiaomi: how to connect to TV

In addition to a digital device, to use the technology you will also need:

• a special adapter for using the widi connection;
• a modern Samsung or LG TV with an HDMI connector.

When the necessary gadgets are prepared, you need to complete several steps:

1. Turn on the equipment. On Xiaomi, go to settings, “additional features” and click on “Wireless display”.

2.Then we find the line with a third-party display, from where we go down to the settings of the “smart” TV. In the proposed list of networks, look for INTEL WiDi, select it by clicking and find your phone model.

3.Press automatic connection, wait a couple of seconds until the equipment “finds each other”. If two devices are successfully found, the name of the equipment brand will appear in the Xiaomi menu.

If the sequence of actions is performed correctly, the picture from the phone display will appear on the screen. Then you can watch videos, play games and edit photos from it.

Widi connection problems

It happens that when the function is enabled on Xiaomi, pairing with another gadget does not occur. The reasons may be the following:

• the “docking” algorithm was performed incorrectly and a retry is required;
• the technology does not work correctly, as a result of which Xiaomi “does not see” another gadget. Then you need to restart the smartphone and re-configure;
• one of the two gadgets does not meet the requirements of the application developer.

In general, Widi on Xiaomi has similar functionality and operating principles, but it transfers data faster and is more versatile in terms of the format and size of imported files.

Nowadays, people have developed many devices that can interact with each other, and compatibility in this is growing every year. Any modern smartphone and tablet can be connected to a laptop, desktop computer and even a TV. Connection is carried out in two ways: wired (using USB, HDMI and other types of cables) and wireless (Bluetooth, Wi-Fi). This feature allows you to carry out many useful actions, for example, watching a movie on your phone can be broadcast on TV using Wi-Fi or other technology. Let's look at several ways to connect Xiaomi Redmi 4X to a TV or another phone.

How to connect to TV

There are several ways to create a connection between TV and smartphone. First, let's look at wired methods, and then wireless ones.
First you need to purchase a special MHL cable. The idea is that there is a micro-USB connector at one end of the cable, and an HDMI connector at the other. Almost all of these types of cables have an additional USB wire that connects to a power source, such as a PowerBank.

The next connection method is wireless technology. Wi-Fi is mainly used. The smartphone must have the Miracast or Wi-Fi Direct function, which is supported by any modern TV with Smart TV. The disadvantage of this method is that there may be noticeable delays in signal transmission, which means the image will be distorted.

There is another wireless method - DLNA. With it, you can work with files directly from the screen, which means you can launch them from there. You need to install a specialized application BubbleUPnP or similar on your smartphone. In this case, the phone and TV must be connected to the same Wi-Fi network. This option works well in Xiaomi Mi5.

How to connect Redmi 4a or Redmi 4 pro to TV

These smartphones most likely cannot be connected using a cable, which means we use Wi-Fi Direct:

How to connect Xiaomi Mi Max and Note 3 smartphones via USB and HDMI

Connecting a mobile device to a TV using a USB cable is quite simple, but there is one caveat. The fact is that after connecting the phone, the TV will recognize it as a flash drive with a file structure, which means there will be no real-time broadcast. Let's perform the following series of actions:

1. Take a Xiaomi smartphone or any other, and a microUSB cable (some now support the USB Type-C standard). It is advisable that the wire be factory wire.
2. We connect the devices and wait for the TV to detect the phone.
3. Using the remote control, open the smartphone directory.
4. You can now play music files, videos and images.

The next method is similar to Wi-Fi Direct. We connect a special cable or adapter to the smartphone and TV (one connects via microUSB, the other via HDMI). An image of the phone screen will automatically appear on the screen. Moreover, all actions carried out on a mobile phone will be broadcast on TV. The picture quality here depends on the phone's resolution.

It is worth noting that modern TV devices with Smart TV synchronize with your smartphone automatically and display the image immediately. In some cases, TV will have to be tuned.

How to control your TV instead of a remote control

You can control your TV from your Xiaomi phone using the infrared port. This technology is called IrDA. Of course, you can control not only TV, but also many other devices, but here we will look at the first option.

An infrared port is available on Xiaomi Redmi note 4 and Mi Max 2. Check the availability of an IR port on your device in the characteristics, there should be a line “IRDA”.

To use your smartphone as a remote control, you need to download Mi Remote from the app store. The program supports not only control of TV, but also media players, air conditioners and other devices.

There will be one peculiarity when loading. The tool will most likely be named in Chinese letters, which means you need to download this particular application with the blue icon. Or it will be called Mi Remote controller.

The wrong choice of TV manufacturer is accompanied by the fact that when you press the buttons in the Mi Remote application, the TV will not respond, so we are looking for the right company. Although there are cases when it is possible to manipulate the TV even when choosing a different manufacturer.

Thus, almost any phone can be used as a TV remote control.

The wireless display on a Xiaomi smartphone implements one very convenient function, with the help of which anyone can display multimedia files from their mobile phone on the screen of a TV, set-top box or projector. In general, it is present in all the latest Android devices, but it is Xiaomi that implements this in the most understandable way without the need to install additional applications.

How to set up a wireless display?

So, in order to set up video broadcasting on the screen of another device from a Xiaomi Redmi phone using a wireless display, several conditions must be met:

• The signal receiver, that is, the device that will play files, must also be equipped with a wifi module - either built-in or an external adapter. Or you can connect the same TV through or even - it doesn’t matter. All possible options are described in.
• Both devices - the transmitter, that is, the phone, and the receiver (TV, set-top box, projector, tablet or other smartphone) - must be connected to the same router and be within the same network. The main thing here is not to confuse the frequency range if your router is and simultaneously distributes several SSIDs at 2.4 and 5 GHz. You need to connect to exactly the same Wi-Fi.

If all these conditions are met, then there is almost nothing further to do. We launch a program on the TV to receive a signal using the Miracast standard - most often it is already preinstalled on the TV or set-top box and is called Miracast, or EZ Mirror, Screen Share or something like that. For Samsung, it is located in the Network settings section.

In short, you need to put it in standby mode for connection from a smartphone. This is what it looks like on a Samsung TV:

And like this - on the projector

On Android, including Xiaomi, the wireless display is transmitted through a program built into the shell. It is located in the “Advanced settings - Wireless display” section

Let's enable this feature. If the TV is correctly switched to the miracast signal reception mode and both devices are on the same network, then it will appear on the Xiaomi display in the list for connection - select it and start broadcasting the smartphone screen.

There is an opportunity to prepare a very useful and relevant article on setting up a wireless screen on tablets and phones that run on the Andriod operating system. Using Miracast technology, we will display the image from the tablet to the TV. All this will work over the air, that is, without wires.

Nowadays, a large number of modern TVs that have Smart TV functions and the ability to connect to the Internet via Wi-Fi also have the ability to work as wireless screens using Intel WiDi or Miracast technology. You can read about these technologies in more detail in a separate article. But, there I wrote more about theory, but in this article there will only be practice.

So, this means that the TV can receive images over the air. And our tablets and smartphones that run on Android are most likely able to transmit this image using Miracast technology. In the settings this is called a wireless screen.

What does all this give us? We can connect our tablet or phone to the TV and everything that happens on the screen of the mobile device will be displayed on the TV. And all this without wires. In this way, you can display a photo or video on a large screen. Watch online videos, or play games on your tablet and display it all on your TV. There are some nuances, which I will write about below, but all this can be done, and now I will show you how.

I just took photos, screenshots, tested everything, checked it and now I’ll share it all with you. Everything is based on a real example, as always!

What do we need?

• The mobile device from which we will display the image on the TV. Android tablet or smartphone. Not all Android devices can work with Miracast technology (wireless screen). But, according to my observations, almost all modern devices can do this.
• A TV that will receive images via Miracast wireless technology from a tablet or phone. Modern TVs can do this. If your TV has built-in Wi-Fi (or external receiver), and has a Smart TV function, then most likely it can display images wirelessly.

I will show using the example of a TV LG 32LN575U and tablet Asus MeMO Pad 10.

To set up such a connection, a Wi-Fi router is not needed, compared to setting up the transfer of medical content.

We connect the tablet and TV for wireless image transmission

All we need to do is turn on Wi-Fi on the tablet, turn on Miracast on the TV and connect the devices.

Enable Miracast/Intel WiDi on LG TV

I will show the example of an LG TV. If you have a TV from another brand, this function may turn on a little differently. In the menu, it may be called differently.

Turn on the TV and press the button on the remote control SETTINGS to go into settings.

In settings go to the tab Net and select Miracast/Intel's WiDi.

Next, turn on Miracast. Simply set the switch to On.

That's it, you can leave the TV for now. But don't turn it off.

Enable “Wireless Screen” on your tablet or Android smartphone

We take our tablet (in my case) and go to settings.

I would like to note that depending on the device (manufacturer, model, Android version, shell), the activation of this function may vary. Just look for the items you need in your device's menu.

In the settings, immediately turn on Wi-Fi and go to the Screen (Display) tab. On the right, select the item Wireless screen (Miracast).

Turn on Miracast by setting the switch at the top to On Below, your TV should appear. Its name will be there. To start wirelessly transferring images to your TV, simply click on the TV's name.

We return to the TV. There should be a request to connect the device. Simply confirm your connection by selecting Yes. If you want this device to be connected in the future without a request, then check the box next to the item “Connect automatically without prompting”.

Next will be the connection status, check and devices will be connected. The image from the tablet will appear on the TV.

All is ready! You can use it.

To turn off broadcasting images to TV, simply click on the TV name again and select OK.

Reconnect according to the instructions.

Using wireless image transmission in practice

I played around a little and tried to understand what this technology could actually be used for. The problem is that with such image transmission there is a slight delay. That is, on the tablet the page has already opened, but on the TV it appears in a second, roughly speaking.

Perhaps, on more expensive equipment, this delay will be less, but it will most likely exist. This connection is perfect for displaying photos on a large screen. Everything is wireless, just the way we like it.

You can browse websites, or, for example, watch online videos.

By the way, I launched the video on the tablet, it appears well on the TV. Although there is a delay, the sound is synchronized with the video. Sound, by the way, is also transmitted.

I tried playing games, but the lag is a little annoying.

Afterword

An excellent technology that allows you to display the image you see on your tablet or phone on a large screen without any wires. Everything connects without any problems and works without failures. At least I didn't notice any problems.

The only downside is the delay in updating the image on the TV. It’s a little difficult to play games, but you can look at photos or videos. Displaying some kind of presentation on TV is no problem at all.

I will be glad to see your feedback and opinions about this technology. How does everything work for you, what application have you found? Share in the comments! Best wishes!
