Miracast, Android phone to connect wirelessly to TV

Hi friends, today I will show you how it works Miracast. If the iOS (iphone, ipad, ipod) have Airplay Mirroring on some newer laptops have WiDi on Android we Miracast or screencast.
Miracast is a protocol that helps us on the TV screen without wires, just you see on your phone or tablet, a kind of HDMI Wireless.
To use miracast we need a phone that supports screen mirroring (Jelly Bean or KitKat), exactly who is operating system and hardware required for it, besides we need a phone Miracast compatible TV or a android MiniPCI you to use it in case you do not have a Miracast compatible TV.
The connection between devices is done via WiFi Direct (not local network), this means that do not need to have a router for whatever connection is directly between the transmitter (phone) and reciver (tv miracast or mini pc connected to tv) .
How does it work exactly?
To simplify everything, Miracast has the mission to send the video signal displayed on the screen of your phone or tablet, directly to the receiver. There are some software instructions that take that signal from the frame buffer, compress it, pack it and send it to the receiver via WiFi Direct (not via router), just to eliminate downtime, this resulting stream reaches the TV or MiniPC connected on TV), here the stream is decompressed and displayed on the screen in real time (almost). Now of course, on some devices it will work better and on others worse, depending on the compatibility and power of the phone. Certainly in time the instructions will be finished, the hardware will be improved and the lag will be reduced, maybe we will have an exclusive chip for Miracast, which will later be able to be used for streaming, video encoding / decoding, archiving …… However Miracast is a useful feature that can sometimes help us enjoy multimedia content on larger screens without cables, even DLNA could do that, playing movies or photos from your phone or PC to your TV but with some limitations.
For those who do not know the phone can run DLNA TV only video, photo or audio, Miracast displays what is seen on the phone or tablet.
Even if your phone supports Miracast, and not necessarily work. I met this problem when I used the Nexus 4 for Miracast connection, connected and disconnected after a few seconds. There must be some compatibility between network faces the transmitter and reciver. In the same setup, with LG G3 not had any problems. Certainly the way the Nexus wifi 4 (Murata) is not well understood and wifi module of MK 908 (Broadcom).
Experience is pleasant to the gaming, where it is almost impossible to play in television watching, the lag is too high.
For movies, youtube, apps, facebook, web browsing and other light things go, unfortunately gaming is not a solution. I would have liked to work with a bluetooth controller connected was a dream mini console without wires.
If you need a fast wireless connection between TV and phone or tablet just for video, photos or music, we tutorial and about DLNA technology.

      Now everything goes very well with the stock rom (latest version). I had problems when I started using passive cooler with the stock rom.

  8. Salut.scuze for offtopic but I have a problem with the phone.
    I have a relatively new samsung s3 mini (2 weeks), when someone calls me with a phone from Allview (than with them I noticed the problem) I answer and it locks, it seems to me that we are connected but I don't hear anything, he doesn't hear nothing. After the call closes I have no sound at all, games, music, youtube… nothing. It only recovers after restart.

    I did not do anything with the phone, not even root.
    Do you have any idea what could be?

    Hi Cristi. I have a question. While launching an application for android through which we can see the articles and video tutorials. If it is more difficult to launch it in the store, at least put the apk on your site and there are enough users to install it. On this occasion we come with impressions about the application and over time, maybe you launch it in Google Play and something else is gathered from the advertising. An application idea, which works and is suitable for your specifics….

  17. Hi. I also have a question: How can I connect a samsung s4 mini to a Lg47LB731 TV. I mention that the TV, sees the phone and vice versa, tries to connect, after which I get the message "the device is disconnected" (on the TV) and on phone the message that it is not connected by screen miroring although it is activated on the phone. Should the TV have any problem? It is under warranty and if that were the problem I would solve it, but I don't want to make fun of it if it's just from the settings .The pictures can be seen from the phone on the TV, only the screen mirror function (phone screen) I can't even display it. This TV often gives me the error "insufficient memory, the application has closed". although apart from youtube and google I didn't install anything on it. That's why I still suspect.
    Thanks in advance TV…

  18. My TV supports miracast (LG 47LB731V) and the android on the phone is 4.4.2 (S4 mini). So after what is written above I should be able to see the phone screen on TV, right? Nothing more false :). I can display video / photo / music / youtube content from the phone on the TV but I can't even play the phone screen on the big screen…. The phone and the TV "see" each other trying to connect but nothing…. I tried with S5 and respectively S5 mini, they are connected but move very slowly….
    Maybe they do resolve in future upgrade ???
    Please help me with some advice that if he had any fault of the TV, return it until Monday but I bought in Germany and living in Belgium and not too crazy so I would walk if he had not any defect, especially since the rest are pretty happy with tv.

  19. I tried a multitude of applications mating Phone-SmartTV, gender iMedia Share, Bubble UPnP, All Cast, Air Wire, WIFI Display, kinome Connect they use now, but none of these applications for Android, not read all movies with subtitles, you open the SmartTV
    If you have no idea who makes application to read subtitles to movies at the time when Android is paired with Smart TV will beg leave a comment if you have no idea.
    Um and another question! Do you know an application for android, transfer files Wifi, ANDRIOID-PC and PC-ANDROID, apart from the one you presented it in an older tutorial
    A good day!

    • Adrian Gudus said

      Have you tried out MX Player? If not, you can integrate the subtitle in the movie, we already have a tutorial on this topic, you can find it using the search box on the top right. Or look for the tutorial "How to watch movies with subtitles on Android phones or tablets"

      • Adrian Thanks for the reply, but I think I was not well understood or not I express myself better in writing!
        It is not MXPlayer! It is perfect with corresponding codecs, I watch movies directions on your phone or tablet with subtitles .... or direct the film about integration subtitle.
        MX player I know very well in all his settings and integration methods under the same.
        They have nothing to do with what I want.
        *** The method is like that of YouTube, when you are on the same wireless network and can to open a video on SmartTV directly from your phone or tablet via a single touch of icons ***

        I say that: When I open a movie on SmartTv, through the method of pairing Wifi devices, with an application from those listed by me above, I can watch the movie in perfect conditions but without subtitles.
        Players of this kind of applications tested me, can not read the subtitles, and applications of this kind do not leave me to set another player base, that would be great to be able to directly open in MX Player, the SmartTV, impossible momentary
        I folosec kinome Connect wifi was conducted to pair the phone or tablet SmartTV site, but the player base of this application can not read subtitles.
        From what I have seen, there are no settings to configure another player base, in applications you've tried it.
        !!! I wondered if you know an application listed in the kind of me, who can open movies with subtitles when mating wifi, phone or tablet with SmartTV site.
        Methods like put subtitles on the film directly with VirtualDub, Total Video Converter,
        a practice the days when phones were "stupid" not to take direct knew subtitles, do not want to go back to those times ..
        And sorry!… I repeat the question!
        Do you know a free application for Android, transfer files Wifi, Android, PC, Android and PC, apart from the one you presented it in a tutorial older.
        Thanks for your understanding if you understand something, should I not return again to the internet in Trencher
        leisure, until I find something useful.
        Have a good day!
