Screen mirroring does not connect to Samsung TV. Detailed instructions for enabling Screen Mirroring mode. How to turn screen mirroring on and off in Samsung Galaxy S4

Good evening!

As promised, I am posting detailed instructions on how to enable Screen Mirroring mode.
There is no need to change anything, reflash, etc., in the car. Everything works for me on factory firmware 33.00.500.

What is Screen Mirroring - most of you probably know what it is and have probably tried this function with Samsung TVs, etc. Still, I would like to describe the essence of the technology a little. If you skip all the technical details, then SM is a copy of the image from the display of your smartphone-tablet on another external display. In terms of purpose, it is very similar to the MirrorLink technology, but unlike it, it does not have the ability to be controlled from the screen of an external device.

What does this give us at our GIs??
- Ability to watch movies, videos, etc.
- Use any navigation program (I recommend using MapsMe when traveling to a region other than your home, and of course our favorite Yandex Navigator)
- Ability to watch online TV (for example through Vintera TV)

What do we need to implement Screen Mirroring
- smartphone with Android 5.02 operating system (also tested on Android 6.01)
- phone cable (I used the one included with HTC phones)
- program MazdaMediaPlayer v.0.3.1 (www.lukasz-skalski.com/po…folio/mazda-media-player/).
- active Wi-Fi connection between the smartphone and the GU

P.S. Thanks to this wonderful guy! Good health to him and his rich wife))))).

But as they say, let's do less words and more action.

Instructions for implementing the above:

I tested on 2 different phones HTC One M7 and HTC One A9

1. Download from the manufacturer’s website the latest version of the program MazdaMediaPlayer v.0.3.1
- to install, first enable permission to install software from unverified suppliers in your smartphone settings.
2. In the smartphone settings, you must activate the item - Debugging via USB
- Everyone has it in different places; on your HTC phone you need to enable developer mode to activate it. Therefore, for each phone we google this moment on the Internet.

3. Activate Wi-Fi and Bluetooth in the GU (if we want to listen to music, etc., we create a connection between them in advance)

4. On your smartphone, enable the Wi-Fi access point and create a random network with a password. Also, in the additional settings, I strongly recommend that you select the channel manually, channel 10, because it connects our cars and smartphones most consistently.

5. On the head unit, wait for your network to appear and connect to it.

6. A message will appear on your smartphone indicating that one active user is connected.
- You need to go to this message and then select a user. In the window that appears, you need to find the IP address that is assigned to your GU. Remember or write down these numbers.

7. Connect your smartphone to the cable (the cable is first connected to one of the standard USB connectors), then you will see a message stating that the USB is in debugging mode, as it should be.

8. Launch the MazdaMediaPlayer program and in the window that appears, instead of the suggested one, enter your IP address, mine were different in the last 3 digits. We are not changing anything else!

10. In the main menu, activate the Screen Mirroring function

11. Enjoy the result, and of course, first of all, launch the navigator)))

Despite the huge number of advantages, this solution has several disadvantages.

1) The phone screen must always be on and its lock disabled

2) If you do not activate channel 10 in the router settings, then periodically (in the interval from 5 to 20 minutes, different each time) the Wi-Fi connection and, accordingly, the SM mode drops off. For this reason, I was able to achieve stable operation only on M7, because... it has the ability to manually switch the channel number when connected, but the A9 does not.

I hope that with my opus, I will help make our lives brighter and happier! Peace and goodness to everyone!

Previously, using DLNA technology, only videos, photos or music could be transferred from the screen of a mobile device to a TV. But now, with the advent of Screen Mirroring technology, the range of available content has expanded significantly, including games and other applications in Full-HD resolution and with stereo sound.

In contact with

However, the electronics market today is able to offer a huge list of various options that compete with each other. Starting, for example, from a wired device Mobile High-Definition Link and ending with wireless analogues, like Miracast.

Some of them involve complete openness, while others are aimed primarily at limited standards and work exclusively with certain brands, this should be taken into account when choosing.

Mobile High-Definition Link (MHL)

Currently the most widely supported open standard for screen mirroring technology. MHL available on almost all smartphones, tablets and TVs (excluding Panasonic products).

To use, you need an additional MHL adapter, which connects to your mobile device via a micro-USB connector. In addition, the adapter has an HDMI connector for connecting to a TV and an additional micro-USB, which allows you to charge the gadget’s battery.

Intel Wireless Display (WiDi)

Technology WiDi, unfortunately, only support Intel laptops equipped with Core i-processors (second to fourth generation) based on the Windows operating system (versions 7 and 8). Compatible TVs are also limited to a select range from LG, Samsung and Toshiba (since 2012), and a full list with additional information can always be found on the official Intel website.

Netgear has developed its own WiDi adapter that provides technology support with HDMI (WiDi ready).

Miracast

Combines all the best from MHL And WiDi, including open standard and wireless communications based on Wi-Fi Direct. Nevertheless, Miracast is still fairly new, and therefore the supported devices include only top-end smartphones and TVs from Panasonic, LG and Sony.

In addition, the latest TV models are equipped with NFC technology, which allows users to initiate screen mirroring technology in the easiest way by placing the device near the NFC tag (LG) or remote control (Sony).

Samsung AllShare Cast

AllShare Cast has a similar Miracast functionality, but at the same time it is an exclusive standard that works with Samsung products. In addition, the company has released a separate HDMI adapter ( AllShare Cast Hub), which is compatible with all modern brands of TVs.

Apple AirPlay

With the help of (second or third generation) you can use proprietary technology from Apple for wireless connection and image output from an iOS device. Apple TV Works with iPhone (iPhone 4s and above), iPad (iPad 2 and later), as well as iPad mini and fifth-generation iPod Touch. In addition, the device is equipped with an optical audio output for connection to a home theater system.

HTC version of the above Samsung AllShare Cast Hub, which similarly supports the Taiwanese company's smartphones. In addition to mirror screen technology, users have the opportunity to use gesture control.

Show screen options

Once in screen, you can perform various actions just as you would in a normal CLI environment. But since screen is an application, so it has commands or parameters.

Dial Ctrl-A And ? . Now you will see all the commands or options on the screen.

Screen key bindings, page 1 of 1. Command key: ^A Literal ^A: a break ^B b flow ^F f lockscreen ^X x pow_break B screen ^C c width W clear C focus ^I log H pow_detach D select " windows ^W w colon: hardcopy h login L prev ^H ^P p ^? silence _ wrap ^R r copy ^[ [ help ? meta a quit \ split S writebuf > detach ^D d history ( ) monitor M readbuf

To exit this screen, you need to click on the " space" or " Enter". (Note that all shortcuts that use " Ctrl-A", are used without quotes).

Disable screen

One of the advantages of screen is that it can be disabled. You can then restore it without losing the information you were doing before. Here is an example script:

You're in the middle SSH-on on your server. Let's assume you download a 400MB patch for your system using the command wget.

The download process will take about two hours. If you disable SSH session or the connection is interrupted due to an accident, the download process will stop. You will have to start all over again. To avoid this we can use screen and disable it.

Take a look at this team. First, you must log into screen.

Then you can create a boot process. For example, on my Linux Mint I upgraded my dpkg package using command apt-get.

Turn screen back on

After you have turned off screen, for example, we will assume that you have disconnected SSH session and went home. At home you run SSH again on your server and you want to see how the download process is going. To do this, you need to restore screen. You can run the following command:

And you will see that the process has resumed from where you left it.

If you have more than 1 screen session, you need to enter the session screen ID. Use screen -ls to see how many screens are available.

Example output

Another way to enable the logging feature is you can add the parameter " -L" when screen is launched for the first time. The command will look like this.

Screen lock

Screen is also a shortcut to lock the screen. You can click " Ctrl-A" And " X" to lock the screen. This is useful if you want to quickly lock the screen. Here is an example of the screen lock output after pressing the shortcuts.

Screen used by Pungki Arianto on mint. Password:

You can use your Linux password to unlock it.

Add screen lock password

For security purposes, you can set a password for your screen session. You will be prompted to enter your password when you want to reattach the screen. This password is different from the screen lock mechanism above.

To protect your screen with a password, you can edit the file “ $HOME/.screenrc" If the file does not exist, you can create it manually. The syntax will be like this.

Password crypt_password

To create " crypt_password", you can use the command " mkpasswd"on Linux. Here is the command with the password" pungki123".

~$mkpasswd pungki123 l2BIBzvIeQNOs

mkpasswd will generate a password as shown above. Once you receive the password, you can copy it to a file" .screenrc" and save. Now file " .screenrc" will look like this.

Password l2BIBzvIeQNOs

The next time you start the screen, turn it off and the password will be asked when you try to re-enable the screen, as shown below:

~ $ screen -r 5741 Screen password:

Enter password " pungki123" and the screen will connect again.

Once you run the screen password request and click " Ctrl-A" And " X", then the output will be this.

Screen used by Pungki Arianto on mint. Password: Screen password:

You will need to enter a password twice. The first time is yours Linux password, the second is the password you put in the file .screenrc.

Exit screen

There are two (2) ways to exit the screen. First - we use " Ctrl-A" And " d" to turn it off. Second, we can use the screen blanking command. You can also use "Ctrl-A" And " TO" to nail the screen.

Currently, Samsung smartphones are one of the most popular devices. These modern gadgets have many services and functions that can be very useful to the user. Today, users are often concerned about issues related to Screen Mirroring Samsung. What it is? How can you use this opportunity? In simple terms, Screen Mirroring Samsung is a functionality that provides access to the smartphone screen from the TV screen. Thanks to this technology, a smartphone user will be able to make wireless connections to the TV and run games on it. You can also view video files stored on your mobile device on your TV. Speaking about Samsung's Screen Mirroring feature, it is worth considering that it allows you to play files stored on your mobile device simultaneously on it and on the TV. To get started with this function, you need to go to the “Network Settings” menu, select the appropriate application there and use various auxiliary functions. These services may vary depending on the Android OS version.

Screen Mirroring Samsung: When is it available?
To ensure that Samsung’s Screen Mirroring feature is available on your mobile device, you need to visit the official website of the manufacturer and find all the information related to this model. If your device meets all the requirements, you can connect from it as follows. First of all, you need to run the service for Screen Mirroring Samsung on your mobile device. Next, search for devices available for connection. Select your TV from the list that appears. TV will be displayed as a pop-up window at the top of the screen. In the above window, you must select the “Allow to connect a mobile device” option. All allowed mobile devices will be automatically connected in the future. You will not need to request approval. If you select Deny, the device will not be able to connect. Also, with this prohibition, synchronization will be unavailable until you change the connection status. If you have previously rejected such a connection and want to enable it now, you will need to follow the following sequence of steps. Go to the "Network Settings" menu item, select network, Screen Mirroring Samsung. In Device Manager, select the desired device and click on the “Allow” button.

Setting up your TV
In some cases, it happens that the device cannot detect the TV in normal mode. Accordingly, Samsung's Screen Mirroring feature cannot be used. In this case, you should not continue searching in the menu of your TV device. You can try the following steps in the menu of the TV itself. First of all, go to network settings and enable Screen Mirroring Samsung feature. You can also start it by pressing the SOURCE button on the remote control. Select the desired option from the list provided at the top of the screen. Next, you need to launch the service on your mobile device. The smartphone can begin to automatically search for available devices. Now select your TV from the list. TV settings allow you to automatically connect without having to approve sync requests. If your mobile device still cannot connect, turn off the TV and turn it on again. You can also manage the connection status of previously used mobile devices. This function will be available only if the devices have previously been synchronized with the TV or the user has set a ban on connection. To use this function, you must complete the following sequence of actions. Go to Network, select Screen Mirroring Samsung. Here you will need “Device Manager”. The TV display will display a list of devices that have previously attempted to connect or have been connected to the TV. Here you can see the connection status - allow or deny. In the pop-up window, you can select “Allow connection”, “Deny connection”, “Remove device from the list”.

Screen Mirroring Samsung: setting it up on your phone
This feature is the easiest way to synchronize your mobile device with your TV. As mentioned earlier, Screen Mirroring Samsung allows you to use your TV as a screen for your smartphone. This makes it possible to wirelessly transfer photos, games, videos and other content and view it on your TV screen. You can manage your content directly from your phone screen. The easiest way to do this is to connect a Samsung Smart TV that supports this function. If you are not sure whether your TV supports Samsung's Screen Mirroring feature, then you need to visit the manufacturer's website to obtain this information. Most models that have been released in recent years have built-in support for this service. But on the other hand, if the above service is not supported by the TV, you have an HDTV. In this case, Samsung's Screen Mirroring feature may be available if you connect your TV to the AllShare cast Wireless Hub.

How to connect to AllShare Cast Wireless Hub
First of all, you need to turn on the AllShare Cast Wireless Hub and your TV. You can connect devices to each other using an HDMI cable. You need to check whether you are connecting the devices correctly. The TV must use a high-definition video port. After a few seconds, the connection status lights should turn red. Once they start flashing, click on the Reset button. After this, the indicators should glow solid red. The HDTV and AllShare Cast Wireless Hub connection is now complete and can work. You can use Netgear PTV3000 for such synchronization. Connecting to the AllShare Wireless Hub is just part of the process to enable Samsung's Screen Mirroring feature. To configure it further, you need to enable such options so that your smartphone is connected and broadcast on the TV screen. To do this, just follow the following sequence of steps. So, press the power button to boot your smartphone. Next, go to the main screen and press the “Menu” key. This is the lower left soft key. A new menu should open with a list of available options. From the list presented, you must select “Settings”. In this submenu you need to click on “Connections”. Next, you should find the Screen Mirroring Samsung tab, go to it and enable the function by simply pressing the switch on the ON icon, which is located on the upper right side of the screen. As a result, the scale on the screen will display from gray to green, thereby indicating that this option is enabled. Immediately after pressing the ON button, your smartphone will begin scanning for available devices that support synchronization. Once the scan is completed, the phone will display a list of available devices. You will just need to select the device that has the name of your AllShare Cast Wireless Hub. Your phone will then be able to connect to the Wireless Hub. This way you can share your TV screen. Also here in the notification panel you can see a special icon that indicates that AllShare is connected.

What else should you know?
While using Samsung's Screen Mirroring feature, you cannot turn off your phone. The very name of this option indicates that a mirror projection of everything that is currently happening on the smartphone will be transferred to the large screen. This means that if you turn off your smartphone and this function is active, the image on the TV will also be turned off.

Is it possible to use Screen Mirroring Samsung with a tablet?
Unfortunately, you cannot use this feature to connect to a Samsung tablet. There is also another way to share the screens of different devices in group mode. This function allows you to interact with devices synchronized with each other. However, there are a number of limitations here too. If you want to connect your tablet to the TV just to watch videos, then this method is perfect for you.

Is it possible to connect a smartphone to a computer?
To use Samsung's Screen Mirroring feature to connect your smartphone to your laptop, you will also need AllShare Cast. Then you need to activate this option on your smartphone and connect via a wireless network. The problem is that your laptop must have an HDMI port to connect to AllShare Cast. If such a port is not provided in the device, synchronization will not be possible. If you have an HDMI port, the connection process will be no different from the steps described above. The same can be said about using Samsung's Screen Mirroring function with a desktop personal computer.

Every Galaxy S4 owner should know that they can enjoy any content on their Galaxy S4 on the big screen (such as smart TVs). You can mirror your Galaxy S4 screen on most TVs or even some projectors very easily. On the Galaxy S4 this is called Screen Mirroring. Sometimes users call it a wireless display, which is used by some other manufacturers.

The Galaxy S4's screen mirroring feature is one of the prominent features of the smartphone. But unfortunately, this feature is underutilized because there are no clear guides for Galaxy S4 owners on how to use Screen Mirroring on Galaxy S4.

This Galaxy S4 guide to using the mirroring feature will help you do just that.

We will look at everything you need to know about the ability to mirror the Galaxy S4 in this article. I will update this guide regularly. If you have any questions or suggestions, please leave them in the comments below.

What is Galaxy S4 Screen Mirroring?

Galaxy S4 screen mirroring (or wireless display) simply duplicates the Galaxy S4 display to your TV or other large screens (such as projectors). In other words, instead of looking at a 5-inch screen, you can watch the Samsung Galaxy S4 on any size TV. The Samsung Galaxy S4 then works as a remote control for your TV.

This means you can watch Galaxy S4 content on your big screen TV using Screen Mirroring. For example, you can watch any video on your TV screen with Galaxy S4. This is a very convenient feature. You can easily share videos or pictures with your family members in the living room with a large screen.

With Galaxy S4 Screen Mirroring, you can also play games on your TV screen. Your Samsung Galaxy S4 in this case is your controller and source of games. In other words, you can play any game not only on your Galaxy S4, but now you can play it on your big TV screen. Is not that great?

You can also use Galaxy S4's screen mirroring to show photos taken or saved on your smartphone on TV to other family members or friends when they come over. Everyone knows that when you look at a 5" screen, it still causes some discomfort and eye fatigue, especially when you are used to watching on a big screen. And when you show several people photos on a smartphone, it’s also not very convenient. Now you can display your Galaxy S4 on your TV so everyone can enjoy your photos.

Is only the image on the screen mirrored? What about the sound?

Although so far I have used words about mirroring the Galaxy S4's "display" or "screen", I can assure you that the sound (audio) will also be mirrored. Galaxy S4 simultaneously transmits both picture and sound.

If your TV has good acoustics, you'll instantly enjoy great audio through Galaxy S4 mirroring. After this, you will probably never want to watch movies on your Galaxy S4 again?? The sound quality is only limited by the quality of the video file itself or your sound system, not the Galaxy S4 smartphone (although the sound quality on the Galaxy S4 is quite good).

In fact, mirroring the Galaxy S4 does not degrade the sound quality on the TV in any way.

The Technology Behind Screen Mirroring Samsung Galaxy S4

Galaxy S4 screen mirroring uses a technology called Miracast, which allows your portable device or computer to send high-definition video (up to 1080p) and 5.1 surround sound securely over a “direct” connection (WiFi Direct) to any Miracast-enabled device.

The Galaxy S4 (including most of its variants) is Miracast-certified. That is, they support this technology. Galaxy S4 Screen Mirroring complies with the Miracast standard. This means that Galaxy S4 screen mirroring works with all Miracast-certified devices.

Miracast is officially supported by Android Jelly Bean 4.2 and later including, of course, Android 4.4.2 KitKat. Google and most other Android phone makers use the term wireless display (like the Wireless Display in the Moto X), which is essentially the screen mirroring of the Samsung Galaxy S4.

Although Miracast technology is officially supported by Android, Samsung supports Miracast through its own implementation - AllShare Cast. You can find this option in some older flagships such as Galaxy S3, Galaxy Note 2, Galaxy Note 10.1. Screen Mirroring in Galaxy S4 is a natural evolution of AllShare Cast and Android Wireless Display.

If you've used AllShare Cast on other Samsung devices before Screen Mirroring on the Galaxy S4, then the technology isn't really new. All devices running AllShare Cast should work perfectly with Galaxy S4 screen mirroring.

How to turn screen mirroring on and off in Samsung Galaxy S4

Enabling screen mirroring on your Samsung Galaxy S4 is very easy. You just go to Settings-Connections-Screen Mirroring(may vary by region). Drag the slider to the right to turn it on. Drag it to the left when you decide to stop screen sharing.

Once screen mirroring is enabled, the Galaxy S4 will search for available devices within range that support Miracast connectivity. Click on this found device to connect to it, following the on-screen instructions.

In general, you already realized that you will need another device, usually a TV that supports Miracast, or Miracast supported via HDMI, in order to be able to mirror the screen. Please read on to find out what you'll need.

What is required to use Galaxy S4 mirroring?

Miracast is an industry solution, so the technology works well on a variety of devices, regardless of brand and manufacturer.

To use Samsung Galaxy S4 screen mirroring, all you need is Miracast supported by your TV. Your Galaxy S4 will immediately find “its” TV as soon as screen mirroring is turned on. This way, you can mirror your smartphone screen onto your TV screen immediately after starting Galaxy S4 mirroring. Most smart TVs released in the last two years support Miracast. You can check this by looking at the specifications for your TV.

Even if your TV does not support Miracast, this is not a problem. An HDMI port is the only requirement for the TV.

If your TV is not smart or does not support Miracast, you can purchase one of the following devices to make screen mirroring of your Galaxy S4 possible.

- HDMI adapter that supports Miracast
- Samsung HomeSync
- Samsung AllShare hub

Now, let's look at these 3 options that will help you decide which is best for mirroring the screen of your Galaxy S4.

Miracast-enabled HDMI Adapter for screen mirroring.

There are quite a few Miracast capable HDMI adapters on the market. Most of them will work with Galaxy S4 .

But Not all of these HDMI adapters are created equal. Delay or lag, this is what you should first pay attention to when choosing an adapter. Some low-quality adapters can cause significant lag when sharing the screen. Sometimes, video and audio don't even sync. This will undoubtedly cause you negative emotions and you may get the unpleasant feeling that the smartphone is to blame. But this is by no means true.

Another factor you should consider is whether you want to share your screen or wireless display with other devices.
Based on my own experience, I usually recommend the Netgear Push2TV - a wireless HDMI video adapter with Miracast. It works with all my devices. This adapter also works with Samsung Galaxy S4 screen mirroring. When you use it to mirror your Galaxy S4, you won't feel any lag. Audio syncs just fine.

This adapter is very useful if you have some non-Samsung smartphones or tablets, especially Amazon Kindle Fire HD or Kindle Fire HDX tablets. It's even officially certified by Amazon to mirror your screen with the Kindle Fire HDX 7, Fire HDX 8.9, and even the new Kindle Fire HD. So, it will be a good idea to buy this adapter to enjoy Galaxy S4 screen mirroring or Fire display mirroring. It works with most other Android phones running Jelly Bean 4.2 and above, as well as the likes of the Galaxy Note 3, HTC One, Nexus 4 and Moto X.

This adapter also supports Intel Wireless Display (WiDi). This means you can use your TV as a second screen for your WiDi-enabled laptop with this adapter.

The price for this adapter is around $60. A USB power adapter is included in the package. But it's surprising that HDMI cable not included. When ordering this adapter, make sure you receive an HDMI cable if you do not have any spare cables at home.

Samsung HomeSync for Galaxy S4 screen mirroring

Samsung HomeSync is actually a personal cloud system (1TB) with many features. Screen mirroring is just one feature in a long list of features. As for mirroring for the Samsung Galaxy S4, this device is not quite suitable.

Most Galaxy phones and tablets support HomeSync. But screen mirroring is only available on Galaxy S3 (some variants), Galaxy S4 (only some variants), Galaxy Note 2, Galaxy Note 3, Galaxy Grand, Galaxy Note 10.1, Galaxy Note 10.1 2014 edition, Galaxy Note 8.0, Galaxy Tab 3 (7.0, 8.0 and 10.1). To take full advantage of HomeSync, you must download the free HomeSync app.

HomeSync isn't cheap. It costs about $300 (1TB).

Samsung AllShare Cast Hub for Galaxy S4 screen mirroring

Samsung All-Share hub is another available solution in case your TV does not support Miracast. The wireless adapter works with Galaxy phones with AllShare capabilities. Of course, Galaxy S4 screen mirroring is also officially supported.

Please note that AllShare hub is only suitable for Samsung devices. It works well for mirroring Galaxy S4 screen without any settings. If you have non-Samsung smartphones or tablets, then it is better to use the Netgear Push2TV Wireless Display HDMI Adapter mentioned above.

What about Google Chromecast? Can it work with the Galaxy S4 screen?

Google Chromecast is an exciting yet affordable device ($35). But at the same time, Miracast is not supported by Chromecast. Therefore, it cannot be used as a Galaxy S4 screen mirroring adapter.

The Chromecast you can use on your TV with the Samsung Galaxy S4 is limited to apps that support Chromecast. At least not through screen mirroring.

Troubleshooting Screen Mirroring Galaxy S4

Here is a list of the most frequently asked questions about using Galaxy S4 screen mirroring. The list is updated regularly. If you have any questions, please post them in the comments below.

Question 1: I enabled Screen Mirroring on Galaxy S4, but there are no devices detected to access the smartphone screen.
A1: Make sure your TV is turned on. If you are using an adapter, make sure the HDMI source is set correctly on your TV. Refer to your TV manual to find and enable Miracast. As a rule, it is turned on in the TV settings.

Question 2: Does the smart TV (or HDMI dongle/adapter) need to be connected to the same network as the Galaxy S4 for mirroring?
A2: No. For mirroring, a private peer-to-peer network will be created between the TV (or adapter) and the Galaxy S4 to share the screen. This is independent of other wireless connections. In fact, internet access is not a prerequisite for Galaxy S4 screen mirroring. This is different from Google Chromecast.

Question 3: What about Galaxy Note 3? Will this guide apply to him too?
A3: This guide also applies and applies to Galaxy Note 3.

Question 4: Can I turn off my Galaxy S4 screen when mirroring to TV?
A4: No, you can't. If you turn off the display on your Galaxy S4, nothing will appear on the TV screen. The TV simply duplicates what you have on the S4 screen. To save battery power when using screen mirroring, you can disable auto-brightness and set the brightness to low.

Q5: Will the brightness or other screen settings on the Galaxy S4 affect the image on the TV when mirroring the Galaxy S4 screen?
A5: No, the screen or display settings in S4 are only for Galaxy S4. The TV will use its own settings as described in the TV manual. They are independent of each other.

It's no secret for a long time that a TV can be used as a computer monitor by connecting it via an HDMI or VGA cable. But few people know that Samsung Smart TVs have the Screen Mirroring function. With this feature, users can display images from the screen of a computer, tablet, phone, or even a phone!

It is about connecting a TV to a computer as a monitor through the Screen Mirroring function that we will talk about. How to display the screen of a Samsung phone or tablet on a Samsung Smart TV is described in detail in this article.

And so, let's go back to our TV and computer.

First of all, you need to check whether your computer supports the technology WiDi(Intel Wireless Display, wireless transmission of content from a mobile device (laptop, ultrabook, tablet) to a TV (Smart TV), developed by Intel. The technology is based on the Wi-Fi standard. Allows you to play 1080p HD video and 5.1 surround sound on compatible monitors ).

Selection of compatible hardware

WiDi technology belongs to the category of hardware dependent; for its operation, a number of requirements must be met. Briefly they can be formulated as follows:

Second or third generation Intel Core i3/i5/i7 processor (not any, see below);
The Intel HD Graphics graphics subsystem, as we know, is built into the above processors;
Intel Centrino Wi-Fi adapter with 802.11n support.

A complete list of compatible hardware can be found on the Intel website.
The list of compatible equipment is constantly expanding, we recommend that you carefully study it if you want to deal with WiDi.

Now let's move on to the setup stage and, in fact, connecting the TV.

Installing the necessary programs

The software that will be used will differ depending on the version of Windows OS that you have installed.

Regardless of OS version: Necessary update software for all Intel devices on the computer (video card, WiFi module, chipset). This is very easy to do using a utility from Intel - Intel Driver Update Utility.

For Windows 7: Download and install the Intel WiDi Remote utility. The installation process is automatic and quite fast. After installation, launch Intel WiDi Remote and in the window that appears, begin searching for available devices. Your TV should appear in the list; after selecting it, click Connect. During the connection process, after successful initialization, a random password number is displayed on the TV, which must be entered on the laptop.

Following this, an image of the desktop appears on the TV. Wireless Display is a full-fledged second display, which, like a wired second one, can operate in two modes: cloning and expansion. Intel software recommends using the second option. The TV resolution was automatically set to 1080p in both modes.

Another feature is that the laptop needs to be switched to the built-in Intel HD Graphics; it will not work on a discrete WiDi card.

For Windows 8 / 10: No additional programs need to be installed. Windows 8/10 already has a built-in remote display connection feature. In order to display the image on the TV screen, you need to go to Start - Settings - Devices. Search for available devices and select your TV from the list. After this, the system will automatically install the necessary drivers and the TV will become available as a second monitor. On the TV, select Screen Mirroring as the source.

If the system does not find the TV, make sure that it is on the same local network as the computer. If the TV is visible, but the connection fails, most likely you have not updated the drivers for your Intel video card.

From the list of options, select Settings. In this submenu, click on “Connections”, find the Screen Mirroring Samsung tab (you can’t go wrong that this is exactly the function you need), go to it and turn on the function by simply pressing the switch to the ON icon located on the top right side of the screen.

A scale on the screen will appear from gray to green, indicating that the option is enabled. Immediately after pressing ON, your phone will automatically start scanning for available devices that support synchronization.

Once your phone completes the scan, it will display a list of available devices. Simply select the device that has the name of your AllShare Cast Wireless Hub.

Your smartphone will now pair with the Wireless Hub and share your TV screen. You will be able to see a special icon in the notification bar indicating that AllShare is connected.

What else do you need to know?

You cannot turn off your phone while using this functionality. The very definition of Screen Mirroring Samsung (what it is, we figured it out) indicates that everything that is currently displayed on the phone’s display is simply mirrored or projected onto a large screen. This means that if you turn off your smartphone while the function is in active mode, the TV image will also be turned off.

Is it possible to use the option with a tablet?

You cannot use this feature to connect your phone to a Samsung tablet. However, there is another way to share device screens in a group mode. This feature also allows you to interact with the content of devices synchronized with each other, although there are some restrictions. If you only want to connect your phone to your tablet to watch videos, this method is perfect for you.

Is it possible to connect a smartphone to a laptop?

To use Screen Mirroring Samsung for a laptop, you will need an AllShare Cast device. Next, you will need to activate the option on your smartphone, search and connect wirelessly. The only problem is that your laptop must have an HDMI port to connect AllShare Cast. If there is no such port, synchronization is unlikely to be possible. If available, the setup process is practically no different from the steps indicated above. Similarly using Screen Mirroring for Samsung PC.

What technologies might be needed?

In order to use the Screen Mirroring feature, you may need one of the following connection types (depending on or computer if you want to use Samsung Screen Mirroring for Windows):

using a High-Definition Link mobile cable (wired mirroring);
using Miracast technology;
using Near Field Connection (NFC) technology.

If you are not using any of the above options, this could be the reason why you are unable to detect your TV and Screen Mirroring Samsung is not working for you.

If the option is automatically disabled

What should I do if Screen Mirroring automatically turns off shortly after connecting? To fix this problem, you need to do the following:

update the firmware;
update the Wireless Hub app to enable AllShare Cast;
check the correctness of the connection;
Check your phone for updates.

If all the above troubleshooting attempts fail, try using another device to test it with the TV and do all the steps again.

Show screen options

Good evening!

P.S. Thanks to this wonderful guy! Good health to him and his rich wife))))).

But as they say, let's do less words and more action.

Instructions for implementing the above:

I tested on 2 different phones HTC One M7 and HTC One A9

1. Download from the manufacturer’s website the latest version of the program MazdaMediaPlayer v.0.3.1
- to install, first enable permission to install software from unverified suppliers in your smartphone settings.
2. In the smartphone settings, you must activate the item - Debugging via USB
- Everyone has it in different places; on an HTC phone you need to enable developer mode to activate it. Therefore, for each phone we google this moment on the Internet.

3. Activate Wi-Fi and Bluetooth in the GU (if we want to listen to music, etc., we create a connection between them in advance)

5. On the head unit, wait for your network to appear and connect to it.

7. Connect your smartphone to the cable (the cable is first connected to one of the standard USB connectors), then you will see a message stating that the USB is in debugging mode, as it should be.

10. In the main menu, activate the Screen Mirroring function

11. Enjoy the result, and of course, first of all, launch the navigator)))

Despite the huge number of advantages, this solution has several disadvantages.

1) The phone screen must always be on and its lock disabled

I hope that with my opus, I will help make our lives brighter and happier! Peace and goodness to everyone!

How to watch photos and videos from your smartphone on TV

Are you uncomfortable viewing multimedia files on the small screen of your smartphone? Today you will learn that to view them on a modern TV from a smartphone, just a few touches of the screen of your mobile device are enough. Let's look at ways to play photos and videos on the SMART TV in your living room.

Methods for connecting a smartphone to a TV

Various technologies can be used to transmit image and sound from a smartphone to a TV: some involve a cable connection, others broadcast the signal wirelessly.

provides interaction between devices based on Android OS and many modern TV models from LG, Philips, Sony, Samsung, Panasonic and other manufacturers. In this case, the connection is established via Wi-Fi.
allows you to stream audio and video files from Apple devices, such as iPhone, to any TV equipped with an HDMI input using your home network and Apple TV media player.
DLNA is a streaming standard for transferring files from any smartphone to TVs that support a wireless network - this is the best option for devices purchased several years ago.

If you cannot establish a connection between devices via a wireless network, you can use an HDMI cable. To do this, the smartphone must support MHL (from USB to HDMI or a special port). An adapter is required for Samsung and Apple gadgets.

Miracast technology allows you to transfer images from smartphone screens directly to Smart TVs. Miracast enables data transfer over Wi-Fi without using a router - through a direct connection between your smartphone and TV. Many Android smartphones from various manufacturers, including Samsung, Sony, LG and HTC, have this capability. TVs with Smart TV support can act as receivers.

Various names for technology

Manufacturers often give the same technology different names. For example, LG, Panasonic and Philips use the name Miracast, while on devices from Samsung and Sony a similar function is called Screen Mirroring and MirrorLink, respectively. However, establishing a connection in all cases is done in a similar way - by selecting the appropriate menu item in the smartphone settings. You also need to activate this function on your TV. The disadvantage of Miracast technology is possible connection interruptions.

Establishing a connection

1. Open the settings of your smartphone (using the example of Samsung GALAXY S 4) and go to the section Connections , select item Other networks , and then . Select items from the TV menu , MirrorLink , .

2. After some time on the screen of your smartphone in the list Available devices The name of the TV appears. Click on it to establish a wireless connection. This procedure can take up to 30 seconds.

3. As a result, the TV will appear in the list of connected devices. After some time, the contents of the smartphone screen will begin to be transferred to the TV. To end the connection, go back to the menu and turn off Screen Mirroring using the green switch at the top of the screen.

4. The corresponding TV menu will also display the name of the mobile device indicating the connection status. After establishing a wireless connection via Wi-Fi, the menu of your smartphone will automatically appear on the TV screen. This completes the setup process.

Miracast Features

1. Interface in landscape format

On many smartphone models, the menu is only available in book format. The Sony Xperia ZL device is a pleasant exception - when you rotate a smartphone connected to the TV, the menu orientation on the big screen will automatically change to landscape.

2. Player and video

When you transfer video from your Samsung GALAXY S 4 smartphone to your TV, only the controls are displayed on the screen of your mobile device. When using other smartphones, the picture is shown simultaneously on both devices.

3. Wireless connection to Sony TVs

And so, let's go back to our TV and computer.

Selection of compatible hardware

WiDi technology belongs to the category of hardware dependent; for its operation, a number of requirements must be met. Briefly they can be formulated as follows:

Second or third generation Intel Core i3/i5/i7 processor (not any, see below);
The Intel HD Graphics graphics subsystem, as we know, is built into the above processors;
Intel Centrino Wi-Fi adapter with 802.11n support.

Now let's move on to the setup stage and, in fact, connecting the TV.

Installing the necessary programs

The software that will be used will differ depending on the version of Windows OS that you have installed.

Regardless of OS version: Required for all Intel devices on the computer (video card, WiFi module, chipset). This is very easy to do using a utility from Intel - Intel Driver Update Utility.
