Wireless connection of the TV to the tablet. We display an image over the air from a tablet or phone (Android) to a TV using Miracast technology (without wires). On the example of an Asus tablet and an LG TV

The popularity of modern portable computer technology is difficult to overestimate. Such demand and unprecedented demand for mobile devices are caused, first of all, by their multifunctionality and ease of use.

This can be seen on the example of tablets. This type of personal computer is capable of performing a wide variety of functions, which makes it a super versatile device.

But what to do if the dimensions of the tablet image do not satisfy? For such cases, manufacturers electronic devices provide universal connectivity personal computers and tablets to TVs to display a better and more formatted image on the big screen. This is convenient and provides unlimited resources for both leisure activities and office work (multimedia files, various presentations, etc.).

By itself, the process of connecting a tablet to a TV is simple, but there are some nuances in the connection methods that directly depend on the generation and “advancement” of the TV.

Connection types

There are many ways to connect a tablet to a TV device:

Through the USB connector.
HDMI connection.
Through an RCA cable and using a signal converter.
Wireless Wi-Fi connection.

Before connecting devices directly, it is advisable to study in detail the instructions of both mechanisms, as well as examine them for the presence of ports for connection.

- USB.The easiest way to connect. The USB cable, as a rule, is already included with the tablet and does not require special skills to operate it. If the TV has the appropriate interface, simply connect a PC to it. But there is one feature - in the case of a USB connection, the tablet will be defined only as a regular flash drive. Therefore, with this type of connection, you should not expect other than standard tasks for a USB flash drive to be performed through a TV. Only USB with MHL/HDMI support has great potential. However, they have such an interface, even among latest devices, only a few examples.
- HDMI.The second most convenient and relevant method of connecting a tablet to a TV. It is represented by a standard interface and a special HDMI port that was originally completed in the device. The connection is made using a wire and without an extra headset, as well as audio or video signal settings. Feature of HDMI combination: high quality signal, sound, image, the ability to simultaneously charge a portable PC and transfer data.
- RCAI. An RCA cable is used only when there are no other ports on the TV for connection and is considered obsolete. RCA or bell/tulip produces transmission analog signal from PC to TV, but the picture and sound quality is poor. In addition, a special adapter with three connectors of different colors is required for connection. As an option to achieve best quality signal, you can use the S-Video connector.
- WiFi.Ultramodern and convenient way, provided that the TV is equipped with a Wi-Fi module. Using this standard allows all signals (music, video, pictures) to be transmitted over local network without any wired connections. The principle of Wi-Fi connection is similar to Bluetooth, so any advanced user can handle this task.

How to make a hood from the cellar in the garage, you can find out. Very useful information, it will be useful to absolutely everyone!

You can find interesting material on how to make a hood from the toilet through the bathroom.

There are two ways to connect wirelessly:

- 1. Through Wi-Fi Direct or Miracast technology. The main condition is the mutual support of these technologies by a TV and a tablet. Data transfer is direct, without the use of a router. If the technology support is one-way (tablet), then you cannot do without a receiver to establish a connection.
  2. With the help of a special software. To do this, you just need to download the desired application to the TV on the tablet, depending on the type of its operating system and install the program. Following the instructions, connect the PC to the TV device.

Connectivity technology

In this video, you will be shown how to connect your tablet to your TV. Enjoy watching!

Consider connecting a tablet to a TV using the example of the popular Samsung brand. Before proceeding to the process, it is worth noting that the connection is always made using the AllShare and Samsung PC Share Manager utilities.

- 1. Download and install software on your computer to detect available devices, primarily a TV.
  2. Go to settings → network/network settings. On the TV remote control, the "settings" button is responsible for this function.
  3. The setting can be done automatically or manually. If you follow the second path, in the window that appears on the dark TV screen, press the “start” command.
  4. Select the type of connection - cable or wireless Wi-Fi.
  5. Wait for the TV to determine the desired wireless network set in the settings.
  6. When issuing a list of available WiFi networks choose yours. You may need to enter a security password. Internet connection is automatic.
  7. The final stage: menu → support → Smart Hub, where Smart Hub acts as a special function on the TV that allows you to work with various Internet sources.

There is nothing complicated in connecting the tablet to the TV, but a few reminders will not hurt:

- - Despite the automatic connection function, it is better to connect the PC and the TV device manually. This makes it possible to enter individual and convenient parameters for personal devices.
  - If the router and the TV are too far apart to improve the quality of signal transmission, you need to minimize their distance.
  - If it is impossible to set the settings, you must reboot the router and try again.

There are many different ways to connect a portable device to the TV. Which one to choose will directly depend on the availability of available connectors in the mechanisms, as well as on their technical characteristics.

It became possible to prepare a very useful and relevant article on setting up a wireless screen on tablets and phones that run on operating system Android. 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.

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

So, it means that the TV can receive an image over the air. And our tablets and smartphones that run on Android, most likely, are able to transmit this image using Miracast technology. In 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 on a large screen, or a video. 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 will share it all with you. All on a real example, as always!

What will we need?

The mobile device from which we will display the image on the TV. Tablet or Android smartphone. Not all Android devices able to work with Miracast technology (wireless screen). But, according to my observations, almost all modern devices can do this.
A TV that will receive an image 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 there is a Smart TV function, then most likely it can display an image wirelessly.

I will show on the example of a TV LG 32LN575U and tablet Asus MeMOPad 10 .

To set up such a connection, wifi router not needed, compared to the media content transfer setting.

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 on the example of the LG TV. If you have a TV from another brand, then this function may turn on a little differently. On the menu, it may be called differently.

Turn on the TV and press the button on the remote SETTINGS to enter the settings.

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

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

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

Turn on “Wireless Screen” on your tablet or Android smartphone

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

I want to note that depending on the device (manufacturer, model, android versions, shells) activation of this function may differ. Just look for the items you need in the menu of your device.

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

Turn on Miracast by setting the switch at the top to position On Below, your TV should appear. There will be his name. To start wireless image transfer to the TV, just click on the TV name.

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

Then the connection status will go, check and the devices will be connected. The image from the tablet appears on the TV.

All is ready! You can use.

To turn off the broadcast of the image on TV, simply click again on the name of the TV and select OK.

We reconnect according to the instructions.

Using wireless image transmission in practice

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

Perhaps, on more expensive equipment, this delay will be less, but it most likely will be. In order to show photos on a big screen, this connection is perfect. All wireless, just the way we like it.

Sites can be viewed, or, for example, watch online videos.

By the way, I launched the video on the tablet, it is displayed well on the TV. Though with a delay, but the sound goes synchronously with video. Sound, by the way, is also transmitted.

Tried playing games but the lag is a bit annoying.

Afterword

An excellent technology that allows you to display the picture that you see on your tablet or phone without any wires. Everything connects without any problems and works flawlessly. At least I haven't noticed any problems.

Of the minuses, one can single out only the delay in updating the image on the TV. It is difficult to play games, but you can look at photos or videos. Bring some presentation to the TV, no problem at all.

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

How can I connect

There are several ways to connect a smartphone to a TV:

HDMI is the most common and convenient option for gadgets with the Android system, which, if there are appropriate cable outlets, allows you to transfer not only data, but also a picture with sound;
USB is an old and reliable method using the wire that comes with all devices. This avoids additional financial and time costs for its search and acquisition. But only data can be transferred in this way, and it is not possible to view media files;
RCA - the well-known "tulips", differ from HDMI in that a separate cable is responsible for each option;
Wi-Fi is the most modern and convenient wireless option, which has undeniable advantages and allows you to implement the entire package of options.

The most convenient way

We will now talk about how to connect a phone or tablet to a TV via Wi-Fi. For the purposes of interest to us, developed as special programs, which are produced by the manufacturers themselves in order to connect devices of the same brand to each other, and universal, suitable for gadgets of different brands.

All specially designed programs for connecting a phone or tablet to a TV are widely available and completely free. Once installed on the device and connected via Wi-Fi, they are automatically synchronized and do not require additional configuration. The main condition is that the network must be the same to which the TV is connected. Here is a short list of them:

Sony TV Side View;
LG TV Remote;
Samsung Smart View;
Philips MyRemote;
Panasonic TV Remote 2;
Toshiba remote.

Of the universal programs, the most common are MediaServer, DLNA Server and UPnP. We install them on a smartphone or tablet, connect the TV to Wi-Fi, allow wireless access for both devices - and enjoy. However, sometimes some brands of TVs and phones do not want to connect.

And the most versatile way to connect a tablet or smartphone to a TV via Wi-Fi is the Wi-Fi Direct function. The main condition for this type of connection is its availability on both devices, and the contact will be made directly - via Wi-Fi without

The tablet as such is a very functional multimedia device, which in itself provides the ability to view video files, listen to music, play various games and much more. Sometimes the question arises: "How to connect the tablet to the TV?". Since the TV has a larger screen diagonal, it will be more comfortable to watch your favorite movie on it. It is also more convenient to listen to music through it, as it has a stronger and better sound, due to large speakers and special sound filters.

Ways to connect a tablet to a TV

Let's look at all the possible options for combining these two devices. One of them will definitely suit you.

HDMI

This method is one of the most common if the tablet has this connector. You need to check which connection the TV supports, and then select the appropriate cable for connection, be it mini-hdmi on one side and HDMI, VGA, S-Video, DVI, SCART, RCA (tulips) on the other.

WiFi

Thanks to wi-fi technology, you can connect your tablet to your TV in many ways.

One of the advantages of this connection is the ability to control the TV using a tablet as a remote control. To do this, you first need to make sure that both devices are connected and are on the same (home) network, then you need to install an application that will access the TV. Such applications are plentiful both from large TV manufacturers and third-party developers. Almost all of these programs give full access to the functions of the TV.

If the user has a tablet in the operating room iOS system, then it suits him prefix APPLE TV. Thanks to this set-top box, it is possible both to fully transfer the content available on the tablet thanks to AirPlay technology, and to receive a wide range of services provided by Apple (new movies, music, sports, popular TV shows, photos, videos and much more).

Also recently, the technology of connecting two devices to each other has become widespread: the Miracast standard. The connection works via Wi-Fi Direct: for a fully working scheme, it is necessary to have two devices compatible with each other, this is the big difference and advantage of this technology from AirPlay. With a Miracast connection, there is no need to purchase an intermediate device, and you can connect to your TV anywhere, whether at home or away. To do this, in the tablet settings, find the “Screen” tab, then the “Wireless Display” item and turn it on. If there is no such item on the tablet, you should select another method of connecting to the TV.

What does this abbreviation mean? MHL, this is Mobile High-Definition Link - this technology supports connection of two devices via data cable with up to Full HD video at 60 frames per second and audio in 7.1 format. The availability of this technology is achieved through the joint work of companies that are part of an organization called the MHL Consortium. These companies include famous brands like: Samsung, HTC, LG, Toshiba, Sony and others.

But what is unique about this technology, because it uses conventional interfaces with HDMI and USB connectors? When connected via an HTML cable, data transfer in Full HD video format will consume a huge amount of energy, and simultaneous recharging of the device through this connector is not provided. And here the MHL adapter comes to the rescue: using software solutions MHL enables the transmission of video and audio High Quality to the TV and charges the tablet at the same time, which is a nice touch. A complete list of gadgets that support the MHL adapter can be found on the website of the developers of the Mobile High-Definition Link technology.

Connection via antenna cable

This type of connection is probably the least likely, for the reason that there are very few such TVs in which the connected cable (antenna) is the only one. But if necessary, this will require a DENDY or SEGA intermediate set-top box or an old VCR. The tablet must be connected to one of these devices, and then to the antenna cable to the TV.

HDMI is the best option for connecting any mobile device. This cable transmits not only high-quality video, but also sound. Most modern plasma TVs are equipped with this connector, but not all tablets have this output. If you plan to use the TV as a monitor, then you should initially choose a Chinese model with a mini-HDMI or micro-HDMI output. To connect, you will need a special cable that connects the HDMI connectors. It is not included in the kit, so you need to purchase it separately. But the connection is carried out without any advanced settings. The only thing to do is to select a special channel - HDMI.

Connecting a tablet to a TV via MicroUSB

To connect via MicroUSB, this port must support MHL. This standard was developed specifically for mobile devices and allows you to transfer high-definition audio and video signals via a USB connection, as well as charge mobile device. To connect, you need to purchase an adapter from USB to HDMI and a cable, as in the previous case. However, while the market is quite rare tablets with USB port MHL.
