Connect your Android phone to your TV using wired and wireless technologies. How to transfer an image or video from your phone to your TV

I very often have to answer questions that sound something like this: “Is it possible to use the TV as a wireless monitor for a laptop or smartphone?” “How to display an image on a TV from a tablet, computer, or phone, but not via cable, but via Wi-Fi?” “How to make it so that everything that is on a tablet or smartphone is displayed on the TV, and that everything is over the air?”

In this article, I will try to answer the questions posed. We will figure out whether it is possible to display an image on a modern TV without a cable, and how to do this using Intel WiDi or Miracast technologies.

Before we get to the main part, in which I plan to tell you how you can turn your TV into a wireless monitor, you need to understand something:

Air may slow down, use cable

No wireless technology will provide the same picture quality that you get over a digital HDMI cable. (at least for now). Yes, I want it wirelessly, but with wireless technology there will be slowdowns, although not much. But playing games or watching movies with some kind of delay in the image is not very pleasant.

You can display videos and photos on TV without any special technology

In this article we are talking about duplicating absolutely everything that happens on the screen of your device onto your TV.

But in order to simply broadcast photos or videos from your computer, smartphone, or tablet to TV via Wi-Fi, you don’t need any special technology. Almost every modern TV supports DLNA technology (if you have a Smart TV, it definitely supports it). Computers and mobile devices can also transmit media content using DLNA technology. Android definitely can do it, iOS too (if I'm not mistaken), and in Windows Phone, this opportunity will appear after updating to version 8.1 (at the time of writing, the official update is still about a month away).

In order to set up broadcasting photos and movies over the air from your computer to your TV, see these instructions:

If the first article is suitable only for LG TVs, then the second can be called universal.

I wrote in a separate article how to display photos and videos from a device on Android: “ “.

Well, if you still need to completely duplicate the picture on your TV, and even without wires, then read on.

Image on TV from laptop or smartphone via Wi-Fi

I noticed that many people want, for example, to start watching an online movie on a tablet in a browser and display it on a TV. But in order to stream a movie via DLNA, you must first download it. Not everyone likes this, and not everyone knows how to download movies on a tablet or smartphone. If you have a Smart TV, then you can watch online movies directly from the TV, and you do not need any additional devices for this. How to do this, read the article.

There are two main technologies that allow you to wirelessly duplicate everything you see on the screen of your laptop or mobile device onto your TV. This is technology Intel Wireless Display(Intel WiDi), and Miracast. Most likely, you have already heard about these technologies, or seen them in the settings of your devices.

If you explain their work in your own words, then everything happens something like this: the image that is displayed on the screen of your computer or mobile device is compressed and transmitted via Wi-Fi to the TV. All this happens very quickly, and the delays are almost unnoticeable.

You simply turn on Miracast, or Intel WiDi on your TV (if it supports this technology, if not, then you need a special HDMI adapter), and on a mobile device or laptop using a special program, start the broadcast. The devices are connected and the picture is transmitted to the TV. By the way, a Wi-Fi network (router) is not needed at all, the TV itself creates a network to which you just need to connect. Something like .

At first glance, everything is very simple. But, at the moment, not all devices support these wireless technologies. Although, I think that in a year this will no longer be a problem.

By the way, Intel WiDi (since version 3.5) Miracast compatible. Therefore, Intel's technology can be considered universal.

Which devices support Intel WiDi and Miracast?

As for computers (laptops), for Intel WiDi technology to work, you need a 4th generation Intel processor, Intel graphics, and an Intel wireless Wi-Fi adapter. As you already understand, not every laptop can boast of such a configuration. Or, you will need a special attachment.

If we talk about mobile devices, they should also have support for Intel WiDi or Miracast. If you plan to use these technologies, then look at the characteristics of the devices and check the availability of these technologies before purchasing.

Intel WiDi and Miracast on TVs

We've figured out the devices that will transmit images over the air, now as for the TVs that will display this same image. The TV must either have built-in support for Intel WiDi/Miracast, or you will need to buy a special receiver that connects to the HDMI connector of your TV.

As far as I understand, almost all TVs from popular manufacturers: LG, Samsung, Toshiba - starting from the 2013 line, and which have support for Smart TV, have built-in receivers and can work with the Intel WiDi/Miracast standard.

If the TV does not have built-in support, then, as I already wrote, an external HDMI adapter will help. By the way, the image flows through it even better than through the built-in one.

For example, the LG 32LN575U TV, an inexpensive model with the Smart TV function, has support for Intel WiDi/Miracast. She looks like this:

Perhaps I’ll somehow demonstrate how this technology works, but that will be in another article.

Afterword

Let's summarize. If you want to use your TV as the main or second monitor for your computer or mobile device, and you do not have an urgent need to connect them over the air, then it is best to do this using a cable. It’s cheaper and the picture quality will be better.

Don't forget that using DLNA technology and Wi-Fi, you can broadcast photos and videos to your TV. But you won’t be able to display the image by launching the game while in the browser or on the desktop.

If you still want everything that is displayed on the screen of your computer, smartphone, or tablet to be displayed on the TV screen, then look towards Intel WiDi and Miracast technologies. If your devices do not support these standards, you will have to buy special set-top boxes and receivers.

If you are just planning to buy new devices and are going to use these wireless technologies, then before purchasing, check whether they support these standards.

That's all. Best wishes!

How to display an image from a laptop, smartphone, or tablet to a TV via Wi-Fi? TV as a wireless monitor updated: February 6, 2018 by: admin


There are several ways to connect a smartphone to a TV. Some of them are capable of turning the device into a full-fledged Smart set-top box, others allow you to launch only specific media files. If you don’t know which one is best to use to connect your phone to TV, then we suggest you read the instructions for each of them. In addition, there is a list of their advantages and disadvantages, which will help you make a choice.

What is it for?

After connecting your phone to the TV, you can use all its functionality on the big screen. Simply put, use a smartphone or tablet as a projector that will transfer the image from the mobile device to the TV. This means that you will be able to:
  • Watch videos, photos, and other media files from your phone;
  • Launch games, applications;
  • Engage in full-fledged Internet surfing;
  • Arrange presentations and demonstrations.
For greater convenience and control, connect a computer mouse, keyboard or gamepad via Bluetooth.

On some TV models (with a built-in Wi-Fi module), after connecting, the phone can be turned into a full-fledged replacement for the remote control. This is convenient when the “native” one is out of order.

Connection via HDMI

The easiest way. Ideally, a smartphone or tablet should have a special mini HDMI connector for direct connection to a TV. If it is not there, then you can use a special microUSB to HDMI adapter or adapter. After that:
  1. Start the TV, in the signal source selection menu (where AV, USB, PC, etc.) select HDMI;
  2. Connect your mobile device using an HDMI cable or adapter (mini USB - HDMI);
  3. The image will automatically adjust to the screen resolution (to fully display the picture). If this does not happen, then go to the phone menu and specify the necessary parameters yourself (image frequency, resolution).
Now all actions performed on the mobile will be displayed on the TV. For comfortable work, you can connect a computer mouse or keyboard via Bluetooth or USB OTJ. To save battery power, turn off your smartphone screen.

Advantages:

  • You can connect a charger to the free USB connector, ensuring continuous operation of the device;
  • Additionally, you can connect a mouse, keyboard, gamepad, flash drive;
  • The TV serves as a monitor.

    Flaws:

  • Not all smartphones support this type of connection;
  • An additional adapter may be required.

    Via USB

    When you connect your phone to the TV via a USB interface, the mobile device will be used as a flash drive. That is, all actions performed on the smartphone will not be duplicated on the screen (as in the case of a connection via HDMI), but it will be possible to launch and play individual media files.


    Connection Guide:
    1. Take the USB cable (which is used for connecting with the PC and charging) and connect one end to the phone, and insert the other into the USB connector on the TV;
    2. On your TV, open the Source menu and select USB. Follow the same steps on your mobile device (the window appears automatically).
    After this, an interface will launch on the TV where you can navigate between system folders on the phone (like an explorer on a PC) using the keys on the remote control. On some models, the TV can automatically check the device for the presence of media files, after which it will offer to play them (you won’t be able to move between individual folders).

    Advantages:

  • All devices supported;
  • There is no need to buy additional cords (the necessary cable is supplied with the phone);
  • The device is recharged directly from the TV, so there is no need to connect a charger.

    Flaws:

  • Only those files that are supported on TV will be played (list of available formats in the instructions);
  • You cannot run games and applications, or use the TV as a full replacement for a monitor;
  • No internet access.

    WiFi connection

    The method is only suitable for modern TVs that have a built-in Wi-Fi module and devices based on Android version no lower than version 4.


    Connection order:
    1. On your phone, go to Settings - Wireless & Networks - Wi-Fi. When the list of available networks opens, click on the button that opens the drop-down list and select “Wi-Fi Direct” (if it is not there, then “Advanced settings”);
    2. The search for available networks to connect via Wi-Fi Direct will begin;
    3. Now open the menu on the TV and look for the “Network” sub-item (usually opened using a separate key on the remote control). A list of available connection methods will appear here. Similar to the phone, select Wi-Fi Direct;
    4. It will begin searching for available devices to connect. To connect via TV, select your mobile phone model from the list. You will be prompted to connect, please confirm it.

    After a few moments, the smartphone connects to the TV and begins transmitting a signal, duplicating the image (and transmitting sound) from the mobile to the TV.

    Advantages:

  • No wires needed;
  • All connectors are free, so the device can be charged;
  • The TV is used as a monitor, so it is used as a large screen for playing media files of any format and launching applications;
  • You can surf the Internet.

    Flaws:

  • Not all TVs and phones support Wi-Fi Direct technology;
  • Battery drains quickly.

    Conclusion

    Only expensive TVs have a Wi-Fi module, and not all phones support Wi-Fi Direct technology. Therefore, its relevance is still a big question. USB connection is the most outdated method. Only those files (audio, photo, video) whose formats are supported by the TV will be played. Because of this, there is a risk that movies or photos downloaded to your smartphone simply will not be played.

    The simplest and most accessible connection method is via the HDMI interface. Every modern TV and most older models support it. Even if your mobile does not have an HDMI connector, it is much easier to purchase an adapter or adapter. It has a small price, but you will get access to all the functionality, you will be able to play any media files, connect other devices (mouse, keyboard, gamepad), and access the Internet.

    • Modern mobile devices are suitable for watching movies and YouTube videos, but they have one significant drawback: the screen diagonal is too small. The displays of even the largest smartphones and phablets cannot stand any comparison with television screens.

    Fortunately, transferring an image from a mobile device to a TV screen is now easier than ever, and this article will cover the most common methods.

    Connecting your smartphone to your TV via HDMI is the most popular option. Many people prefer HDMI, because high data transfer speeds and high-quality pictures are guaranteed. However, connection is only possible if the Android smartphone itself has the appropriate connector - usually it is located next to the micro-USB.

    Please note that you need a special HDMI cable: one end should have a standard Type A connector, the other should have a Type D connector, similar in appearance to the charger connector.

    HDMI A-D cable

    If you cannot find an A-D cable, you can use a special MHL to HDMI adapter, which is usually included in the television set.

    MHL to HDMI adapter

    Having connected two devices via a cable, on the TV itself you need to select HDMI as the signal source, after which the same image will appear on the screen as on the smartphone display. If there is no image, you should adjust the settings on the gadget (path “Settings” “HDMI format”).

    Connect via USB

    The method of connecting a gadget to a TV via USB is suitable if the TV itself is equipped with a corresponding connector. You will need a USB–micro-USB cable, which can be found included with almost any smartphone.

    USB-micro-USB cable

    It will not be possible to duplicate the image from the gadget’s display on TV, but with this connection, the smartphone can be considered as a USB drive. Data management is carried out via the TV interface. Modern TV devices can play not only videos and films of certain formats, but also text documents and presentations.

    Please note this connection feature: both devices must be turned on - if the gadget is turned off, the TV will not recognize it as a drive.

    Connect via Wi-Fi

    You can connect your phone to your TV without cables - just use one of the software products from the manufacturing companies. For example, many of Samsung's models have the AllShare function, which allows you to connect to a TV of the same brand in a couple of clicks. To use this feature you need:

    1. Activate your home Wi-Fi network.
    2. Connect both devices (TV and Samsung phone) to Wi-Fi.
    3. Activate AllShare.

    Other major manufacturers have an analogue of AllShare. offers to use Smart Share, through which the smartphone connects to the TV in almost the same way as through Samsung technology. Apple devices can be connected via AirPlay, however, you will have to additionally buy a special set-top box.

    The listed methods have a common disadvantage: you can only connect the gadget to TVs of the same brand. Therefore, a reasonable question that owners of rare TV brands will definitely ask: is it possible to connect a smartphone via Wi-Fi, bypassing branded applications?

    We use Wi-Fi Direct

    The advantage of this technology is that setting up a home Wi-Fi network and registering both devices in it is not required - the gadget connects to the TV via Wi-Fi directly. The important thing is that both devices must support this feature. “Connect” happens like this:

    1. Wi-Fi Direct runs on the gadget. The user needs to follow the path “Settings” “Wireless networks and connections” “Wi-Fi Direct”. You should click “Activate” or “Ok” (depending on the model).
    2. The function starts on TV. You need to go to the menu, select “Network” and find Wi-Fi Direct in the list of options. After activating the function, a list of devices available for connection appears - from the list you should select the smartphone that was configured earlier.
    3. The smartphone receives a request to confirm the connection. Just click “Yes” and use Wi-Fi Direct for your pleasure.

    other methods

    You can connect devices differently:

    Via Miracast technology. The technology developed by the Wi-Fi Alliance is similar to Wi-Fi Direct - the connection is also established directly, and no additional router is needed. This ensures high connection speed. There is one difference from Direct: Miracast can be used even if the TV does not support this function or does not have a wireless module at all. To connect in such cases, you need an external unit (say, Prestigio Multiscreen) - a device that looks similar to a USB flash drive.

    External block Prestigio Multiscreen for connection via Miracast

    Miracast also has a disadvantage: only the latest models of TVs and smartphones are equipped with this technology. Miracast is supported by Android smartphones with Jelly Bean OS (4.2) and higher.

    Via Chromecast device. This device, an innovation from Google, is inserted into the HDMI connector of the TV and broadcasts content from the smartphone to it.

    Google Chromecast device

    Chromecast has a significant advantage over other connection methods: this equipment works not only with Android, but also with gadgets on Windows and iOS.

    Via xBounds device. iPhone owners will be upset, but xBounds only works with Android. The principle of operation is the same as that of Chromecast, and even in appearance these devices are similar.

    xBounds device

    Interestingly, when connected via xBounds, even low-resolution videos will appear on the TV screen in high quality.

    Conclusion

    If a user plans to connect a smartphone to a TV, he should think about this point before purchasing the devices. To avoid connecting via a cable and not feel tied down by wires, it is better to include the presence of Miracast technology (or Wi-Fi Direct) in the list of mandatory requirements for the gadget you are purchasing.

    Modern phones, although they have large screens, are still inconvenient to view various photos and videos. However, current technologies make it possible to connect a mobile device to a TV and display any picture or video on the big screen. Subsequently, we will present all the ways to display an image from a phone to a TV.

    What does such a connection provide?

    After connecting to the TV, you will be able to use all the functionality of your phone on the big screen. This means that you can:

    • play movies, photos;
    • play games, run various applications;
    • work fully on the Internet;
    • carry out various presentations.

    Moreover, on some TV models, the connected phone can fully take over the functionality of the control panel. An excellent solution if your own one is broken. As you can see, it’s worth figuring out how to transfer a video or other media file from your phone to your TV.

    Connection highlights

    Modern devices provide wired and wireless connections. Regardless of the chosen method, all manipulations can be performed by each user.

    You can work with any smartphone, regardless of manufacturer and operating system. All you need is to purchase a special adapter for HDMI, USB, etc. Some modern smartphones are immediately equipped with the necessary connector for output to an external screen.

    All connection methods via cable

    First of all, let’s decide how to broadcast video from a phone to a TV using a cable.

    Via HDMI

    The most convenient and simple technology. To do this, you will need to get a microUSB to HDMI adapter and perform the following manipulations:


    If for some reason the setup does not start, open the gadget menu and set the necessary parameters manually. After these steps, the picture from the mobile will be broadcast on TV.

    Via USB

    This method does not allow you to duplicate the image, since the TV sees the phone as a drive. However, it will be possible to view individual video files. The connection principle is as follows:

    1. We connect the USB cable to the smartphone and TV.
    2. On the remote control, press the Source button and set the desired signal source, and carry out the same manipulations on the mobile phone.

    A menu will open on the TV, allowing access to all folders on the phone. Using the TV remote control you can open all available files. This option is convenient for watching movies or photos stored on the phone.

    Via MHL

    This method allows you to take a signal from the data connector. A special MHL adapter is required for this. The subsequent connection is completely identical to the previous options.


    Of course, you need to know how to watch a movie from your phone on a TV using MHL, but the option is not the most convenient. To ensure a stable video signal on the TV screen, you need to add additional 5 V power to the adapter. In this case, the mobile device does not charge, and accordingly, the available energy reserve is quickly consumed. In addition, you won’t be able to watch with a maximum resolution of 1080p, as there are strong interruptions.

    Using SlimPort adapter

    The SlimPort standard is found on LG and Samsung devices and has become an alternative to MHL. How to play video from your phone to TV in such a situation is to use a special adapter. Compared to the previous version, a better and more stable picture is provided. In this case, the adapter does not require additional power. Although the device has a port, it can be used to recharge a mobile phone.


     This is what a SlimPort adapter looks like

    It should be noted that the technology is demanding on the cable. It is better to purchase a branded product, since budget options may create interference or not work at all.

    Wireless Connectivity Options

    Naturally, many people don’t want to bother with wires and different adapters, so a wireless connection looks like a profitable alternative. All you need to do is pair via Wi-Fi or router and that’s it. Now let’s take a closer look at how to display video from your phone on your TV using a wireless connection.

    MIRACAST

    Miracast technology provides direct data transfer via Wi-Fi between a smartphone and TV. Almost all modern Android smartphones are equipped with similar functionality. As for TV, only models that support Smart TV.

    It is necessary to take into account that manufacturers call this technology differently:

    1. LG, Panasonic and Philips - Miracast.
    2. Samsung – Screen Mirroring.
    3. Sony - MirrorLink.


    Regardless of device models, the connection is identical:

    • go to the mobile menu and open “connections”;
    • select “other networks” and launch the desired technology;
    • in the TV menu select Miracast, MirrorLink or Screen Mirroring;
    • a window with available devices will be displayed on the mobile screen, where the name of the TV will be;
    • By clicking on it, all you have to do is wait for synchronization.

    As soon as a stable connection is established, the contents of the smartphone screen will be displayed on the TV.

    DLNA

    DLNA technology is considered absolutely universal. Many modern Android devices are equipped with it right away. For example, Sony Xperia owners don’t even need to figure out how to transfer the desired image from their phone to their TV. They are required to click on a special icon above the image and select their TV. In just a few seconds you will be able to view the selected media file on the screen.

    Apple devices are not equipped with DLNA, but with the help of a special application PlugPlayer, Twonky Beam, this inconvenience is safely eliminated.

    Wi-Fi Direct

    This technology is available on all TVs with Smart function. However, the smartphone must be based on Android and not lower than the fourth version.

    Connection principle:

    1. On your mobile phone, open the list with valid Wi-Fi connections.
    2. We find Wi-Fi Direct; if it is missing, we find it in additional settings.
    3. On TV we similarly find the Wi-Fi Direct connection.
    4. The search will begin, after which a connection request will be sent to the phone, all that remains is to confirm it.

     Setting up Wi-Fi Direct on an LG TV

    A convenient way to display any picture and watch a movie online.

    Remotely enable video from YouTube

    If the TV has the YouTube application, this means that it can be controlled from a smartphone. To do this, open the application on the TV. In its settings, select the smartphone we need. A code will appear on the screen. We go to a similar application on the mobile and in its settings we find “connected TVs”. In a special window, enter the code and click on the “add” button. All that remains is to activate the desired video on YouTube on your phone.


    In conclusion

    There are many ways, and all of them are described in detail in this article. By following the instructions, you will instantly be able to watch your favorite video or movie on your TV that was just broadcast on your phone.

    The telephone and the TV seem to be completely different, incompatible things. But time moves forward, and technologies and techniques for communication and image transmission are changing. Today, many people want to know how to connect a phone to a TV via USB for the following reasons:

    • the need to watch videos when the user visits different sites, especially YouTube. High-quality video is best watched on a big screen;
    • desire to look at photographs. The small screen of a mobile phone does not allow one to evaluate the contents of the image;
    • the desire to get a good experience from colorful games launched from a cell phone;
    • discrepancy between storage capabilities and playback capabilities of high-quality video material on mobile phones.

    The fact is that the higher quality the video, the larger the file size. Modern phones are equipped with significant amounts of internal memory and support flash drives to increase it. They can store top-notch quality movies. But you shouldn’t watch movies on mobile phones, since modern TVs use new technologies for processing frames and images. The screen size allows you to clearly see what is happening.

    Compare the impressions left after watching a Blu-ray quality film if the diagonal is 70 and 3 cm respectively (see photo)

    But TVs do not have the ability to store files. Therefore, to enjoy the movie or video you are watching, you need to display the file on your television screen. In this case, the smartphone must be connected to a suitable port.

    Ports of the type in question are common, so the answer to the question - is it possible to connect a cell phone to a TV via USB - is obvious. Today this is possible. The main methods are described below.

    Displaying what is happening on the smartphone on the TV screen

    Let's say a person needs to visit some sites to get a good look at their content, or play on a wide screen, using only a mobile and television source. Roughly speaking, a person wants to reproduce the contents of the phone display on the TV screen. Let's assume that the phone has a microusb connector, and the TV has an Hdmi connector. This situation happens often. To solve the described problem, you need to use a microusb-hdmi cable or adapter using the following sequence of actions:

    • connect the cable to the hdmi television connector;
    • turn on the TV;
    • a menu will appear. Click on the media device item;
    • select the appropriate hdmi output;
    • Let's start working with the phone.

    Thus, the owner of the smartphone performs the desired actions, and their result is shown on the TV screen.

    When choosing an adapter, you should pay attention to such parameters as the type of signal, supported resolutions, surround and compressed sound channels, and material of manufacture. Also, compare the number of contacts of the adapter and the phone cable. It is advisable to purchase an adapter with the MHL standard, specially adapted for connecting phones to equipment capable of operating in full HD mode. An adapter like this charges the device while video is being transmitted.

    Moreover, some modern models support the new Mhl 3.0 standard. It allows you to transmit 4K images at a resolution of 3840x2160 and a frame rate of 30 frames per second. It supports True HD and DTS HD Ma audio formats used in Blu-ray.

    Manufacturers of some brands have implemented the Slimport standard. Here are a number of models that support it:

    • Lg G2;
    • Lg G3;
    • Lg g4;
    • Nexus 4;
    • Nexus 5;
    • Nexus 7 Tablet;

    With this type of connection, there is no need to connect power or make Android settings. Video is transmitted without decoding and without output delays. However, the standard requires the use of high-quality wires. Therefore, it is better not to buy cheap options.

    Transferring video to a TV with a Vga connector

    The Vga connector is typical for older TV models. But let's assume that using hdmi connectors is unrealistic. There's nothing you can do, you need to connect to the old TV in one of two ways. The most convenient way is to purchase a microusb-Vga adapter. But they are rarely sold in Russian stores, and the quality of such products is unknown.

    The second method involves using two adapters, the sockets of which are visible in the photograph.

    You should connect a microusb-hdmi adapter to the smartphone, connect it to the hdmi-vga adapter, and insert the VGa end into a suitable socket on the TV. Thus, the result obtained will be determined by the characteristics of the two cables.

    View files from mobile

    Let's say your mobile phone or card stores photos or videos that you just need to watch. Then you will need a microusb-usb adapter. The TV must have the specified type of connectors. In this section, you will learn how to connect a mobile phone to the TV using a USB port. You should proceed like this:

    1. The cord is connected to the microusb telephone connector.
    2. The smartphone will prompt you to select a connection mode. The storage mode is selected.
    3. Using the remote control, the TV is switched to media reading mode.
    4. The “Multimedia”, “usb” or other button is pressed, depending on the TV model.
    5. When there are no such buttons, click “Source”.
    6. The Signal Source menu appears. A suitable section is selected. See an approximate view below.

    The connection through the port in question may be prevented by settings in the file transfer mode, called MTP. It is often used by default when the smartphone recognizes the connected device. Then you need to configure booting in drive mode. To do this, the following sequence of steps is performed;

    • download the Android terminal emulator program;
    • launch it;
    • in the window that appears, enter su (superuser);
    • You will be asked for master user rights. We confirm it;
    • dial the line setprop persist.sys.usb.config mass_storage,adb ;
    • press the enter key;
    • type reboot, then press the same again;
    • the phone will reboot.

    When you need to boot again through the above mode, enter the Android commands:

    • Su (confirm);
    • Setprop persist.sys usb.config mtp.adb;
    • Reboot.

    Problem situations

    When trying to connect, two main types of problems are possible. These are problems recognizing devices or video files.

    They are usually caused by the following reasons:

    1. Incorrect connection. The solution is simple. The connected telephone must be connected again following the instructions.
    2. Using MTP mode by the Android system. It can be solved either by the described method or by replacing the phone’s firmware.
    3. The TV does not read video files. This happens because this type of technology does not support all file formats. The only way out is to copy the file to your computer and then convert it to a supported format using special programs. The most commonly supported files are mp4 and avi. Sometimes the video is re-shot.

    Conclusion

    The method of using the phone's USB port is determined by the purpose of the connection. If you need the TV screen to show the phone screen, then either microusb-hdmi adapters or their combination with hdmi-Vga are used. If you just need to view the file, then a connection is made using the microusb-usb type. The main problems are caused by incorrect file format or MTP settings. Choose methods for connecting communication devices and television equipment based on your needs.
