Connect laptop to TV wi-fi

With WiDi technology

This technology makes it easy to duplicate the screen from a laptop to a TV. In this case, you do not need to share anything. For gamers, this will be a real boon, and you can play your favorite games on a wide screen.

But there are a few nuances. This technology works between a laptop and an Intel processor and a Wi-Fi module from the same company. The TV must support the same Miracast (WiDi) technology. On modern TV sets, almost everyone has it.

ATTENTION! Intel no longer provides support for this technology as of December 15, 2016.

  • First, let’s check if there is WI-DI on the TV. Let’s just rummage around in the settings.
  • Downloading Inetl WiDi from the office. site.
  • Install on PC and run.
  • Click “Connect” or “Connect”.
  • Choosing a device to connect. You may need a code to connect. it will be displayed on the TV set.
  • At the very end, select the screen duplication mode or “Duplicate”.

Home Media Server

This free program allows you to make an offline connection between your TV and laptop. Suitable for some Sony TVs and lesser known brands. The program is free, so it’s not a fact that it will work with your equipment. this is the warning on the site when downloading.

  • Download the program from the official website.
  • Install.
  • Next, when you start the program, we will start looking for available TVs. Just click on your TV model. If there is no data when searching, then make sure the TV is turned on.
  • Now the program will offer to share folders with movies, music and photos for general use. To add a separate folder, click “Add”.
  • At the end, open the extended folder from the TV and start the video. To do this, look in the settings menu for opening a DLNA server.

For MacBook with iOS

  • Click on the main button in the upper left menu.
  • Go to “System Preferences” and click “File Sharing”.
  • Click the checkmark as in the picture above. In the “Shared folders” section, you can add any, to do this, just click the plus sign. As soon as the folder is added, select it and set “All users” to the right, and “Read-only” access in the right column.

Setting up DLNA wireless connection

DLNA or Digital Living Network Alliance is a technology that allows you to exchange different devices, media files over one local network. In our case, it will be a laptop and a TV.

The TV does not see the folder on the local network

Check the folder sharing setting again. Check that the “Home network” is in the network control center, and there is no password request available.

Make sure your PC and TV are on the same subnet. To do this, you need to look at the IP address of the PC.

connect, laptop, wi-fi
  • We launch the console on Windows. Press the WinR keys at the same time.
  • Next enter CMD and click “OK”.
  • Write the ipconfig command and press Enter.
  • Look, my TV is not set to the correct settings. And the IP address of the TV ( is in the 173rd subnet and of course he does not see my laptop. This means that the TV has a problem receiving settings from the DHCP of my router. Well, it’s okay. let’s set it up manually.
  • Click “Configure IP” and set the value.
  • IP address we only changed the subnet to our first one. But you can have a different subnet as well. The most important thing is to put the 3 digit. the same as on the laptop’s IP.
  • Next, according to the standard, set the mask
  • The last two addresses are set from the subnet. For the first subnet.
  • Save network settings.
  • Setting up your TV

    • Now we go to the TV set and turn it on. I have a Samsung screen. Go to the settings menu and look for the “Networks” section. Further “Network settings”. We select the connection via the “Wireless network”. The TV will search for available air connections. After searching, you need to select our Wi-Fi network and connect by entering the password. After connecting on the TV, you will see the IP setting of your device.
    • Depending on the company and the firmware of the TV system, in the menu you must select the connection to the PC. But it is possible to connect to the AllShare server. How to set it up. I’ll tell you a little lower in the article.

    How to quickly connect your laptop to a TV over Wi-Fi?

    The TV, anyway, has a wider picture than all modern laptops. Therefore, it is much more convenient to watch films, pictures, photographs on it. Better yet, download movies and watch the whole family on the big screen without straining your eyes. Roughly speaking, there are two ways to connect to the TV:

    • By cable. there are HDMI and DVI connectors for this. In this case, the user must have wires. But this is very inconvenient, constantly dragging the laptop to the TV, throwing a cable about which someone might stumble.
    • Wirelessly. the TV set connects to a wireless local Wi-Fi network. At the same time, he can have access to the Internet, shared folders and local network data. Roughly speaking, you can download movies to your PC or laptop, make the folder open for public access and watch media on your TV. In this case, you do not need to throw the cable, carry the laptop somewhere, connect it.

    Today in the article we will tell you how to simply connect a laptop to a TV via WI-FI and play media files.

    HELP! If in the process you have any difficulties in connecting, then leave your detailed questions in the comments, and I will try to help you.

    Thunderbolt is a relatively new interface designed to transfer any type of data at very high speeds. Found most often on MacBooks and can be used to connect them to an external monitor or TV.

    Since there are no TVs with Thunderbolt yet (and if there are, the author does not know them), to connect the MacBook, you will need additional equipment. a Thunderbolt to HDMI adapter and an HDMI-HDMI cable.

    Cable connection

    The HDMI digital interface, which supports the transmission of FullHD quality images and multichannel sound, is perhaps the best way to cable a laptop to a TV, since most mobile computers are equipped with this interface. Modern TVs also have an HDMI port. To connect the devices, a cable of the appropriate type is enough: HDMI-HDMI or micro- (mini-) HDMI-HDMI (if one of the connectors is small).

    Connecting the cable to the ports is permissible only after turning off the power of the devices (otherwise, they can be damaged). Switching between displays (laptop and TB) is done by pressing the FnF key combination, where F is a function key with an icon in the form of two screens, for example, as in the photo below.

    The parameters of the image display on the secondary display. view, resolution, etc., are configured through the Control Panel, the “Display” applet and the section “Configuring Display Settings”.

    Audio is configured through the Sound applet. The TV speakers will appear in the Playback device list. To make them the presenters, open the context menu and check “Set as default”.

    The VGA analog interface is also very common on laptops and TVs. A TV connected to the laptop with a VGA cable will only be able to reproduce the image, and the sound will come from the laptop speakers.

    Connection of different types of interfaces by means of adapters

    Remember: the less transformations and breaks in the transmission medium, the higher the picture and sound quality on the playback device. Direct cable connection. from laptop port to TV port, always gives better results than using adapters.

    If your laptop has only a VGA port and your TV has VGA and HDMI, it is preferable to use a straight VGA to VGA cable over an HDMI to VGA adapter and HDMI to HDMI cable. The adapter does not improve the analog signal to the digital level, but simply converts it to another format, often with a loss of quality.


    DisplayPort connectors are less common on laptops than the first two. This is also a digital interface, like HDMI, capable of transmitting both image and sound.

    Wi-Fi Miracast, WiDi and AMD Wireless Display

    You probably remember what Wi-Fi Miracast and WiDi (Intel Wireless Display) are from the previous article. We hasten to please you: these technologies are supported not only by smartphones, but also by mobile computers. However, not all, but only those equipped with Intel Core i3 / i5 / i7 processors of the second and subsequent generations.

    WiDi and Miracast support in different Windows versions is implemented differently. Namely:

    • 2nd Generation Intel Core i3 / i5 / i7 processors can only use WiDi version 4 features in Windows 7 and 8.1. Windows 10 does not support WiDi and Miracast.
    • 3rd generation processors support WiDi 4 only in Windows 7, G8 and 10 support Miracast.
    • 4th generation processors have migrated to support WiDi version 6 (modern). In Windows 7 and 8.1. no restrictions. On Windows 10, only with a Wi-Fi adapter released after 2013. Computers with older wireless adapters and Windows 10 can only use Mirakast.
    • Fifth-Sixth Generation Processors Support WiDi 6 Unlimited.

    AMD-based notebooks are also capable of transmitting images to TB over Wi-Fi. The technology they use is called AMD Wireless Display. This is, so to speak, an analogue of WiDi, developed by AMD for wireless connection of its devices and Miracast-compatible TVs.

    Connect Laptop to TV via Wi-Fi | NETVN

    AMD Wireless Display is officially supported on Windows 8, 8.1 and 10. To check if the processor is compatible with this technology, the manufacturer recommends the proprietary AMD Catalyst Auto Detect utility.

    Connecting to a TV

    An access point is not required to transmit an image from a laptop to a TV screen using any of the above standards. It is only necessary that both the laptop and the TV receiver support Mirakast (as you already know, in the absence of such an option on TV, an external adapter can replace it).

    So, before establishing a connection, make sure that Wi-Fi is turned on on both devices. Next, we activate the Miracast function on the TV. In which menu it is located, it should be indicated in the instructions. Next, go to the laptop.

    If you have Windows 10, press WinP on your keyboard to open the Project menu. If you want to. for the desktop to be displayed both on the computer and on TV, select “Repeating”; to display the picture on TV, select “Second screen only”.

    If you have Windows 8.1, open the charms bar, go to Devices. Projector and select the Wireless Display option. After that, the TV will work as a monitor.

    To connect via WiDi, Intel previously offered users its own tool. the Intel Wireless Display utility, but now it is not available.

    AMD Wireless Display has always only used the above Windows interface.

    DLNA is another technology that allows devices on your home network to share multimedia content without complicated settings or wires. However, not only wirelessly. one or both of the mated devices can be connected to the network via a cable. Unlike Mirakast, DLNA does not provide the ability to link them directly.

    A TV connected to a laptop via DLNA will not replace a monitor. it will play only those multimedia files that the user chooses, and the desktop, shortcuts and everything else will remain on the laptop display.

    To connect a mobile computer to a TV via DLNA, three conditions must be met:

    • The entry of both devices into one local network. No internet connection required.
    • TV technology support.
    • A modern operating system (Windows 7-10) installed on a laptop, or separate software for creating a DLNA server. For Windows XP and Vista users, for example, Windows Media Player 11-12 version.

    DVI, S-Video

    Ports of these types today can only be found on old laptops, and they are used mainly to connect to no less old TVs.

    Wireless connection methods

    Via DLNA

    The first method, which makes it possible to display an image from a laptop on a TV screen, is through DLNA. To connect a laptop and TV via Wi-Fi in this way, you must first connect them within the same network. Most modern TV models have support for a technology called Wi-Fi Direct. Thanks to it, it is not even necessary to connect both devices to the same router, because the TV automatically creates its own network. It remains only to connect a laptop to it.

    Now let’s say directly about the output of the image from the laptop to the TV display. To do this, you first need to set up a DLNA server. That is, you need to open access to the directories with files of interest to us within this network. After that, we connect to the home network, and you can see that the “Video” and “Music” directories have become available on the TV. These directories will automatically be available to other devices on the network on Windows 7 and Windows 10 operating systems.

    If you need to open access to any other directory, then you can do this in the “Access” tab, which can be found in the “Properties” item of each folder.

    There you need to select the “Advanced Settings” item, in which you can see the “Open Sharing” field. We put a tick in front of it, and then click on the “Ok” button so that the folder becomes visible on the TV.

    You can sync your PC and TV a little faster if you use File Explorer. In its menu, you will need to select a section called “Network”. After that, a message will appear on the screen, which will say “Network Discovery”. You need to click on it, after which an assistant will appear on the screen. To adjust the synchronization of the transfer of the duplicate image of the computer to the TV, you should follow its recommendations that will be displayed on the screen.

    After DLNA is configured, you should take the TV remote control to check the available external type connections. After DLNA is activated, you should select the content you want to play. To do this, right-click on the file icon, in the context menu that appears, select “Play on” and click on the name of your TV.

    In such a simple way, you can connect a laptop to a TV via Wi-Fi thanks to a DLNA connection. The only thing you need to know about playback is that MKV format is rarely supported even by modern TV models, which is why such a file needs to be converted to another format before playback.

    Connection methods

    If we talk about connection methods, then they distinguish:

    But few people choose wired connection methods today, because few people these days want to tinker with various kinds of wires, adapters and adapters.

    And often, setting up with such connection methods takes a lot of time and is fraught with difficulties. For this reason, a wireless connection is much more relevant today, because it makes it possible to connect a laptop to a TV without a cable relatively quickly and easily. There are quite a few possibilities to create a wireless connection between a laptop and a TV over Wi-Fi. But we will look at 3 of the most popular:

    • via WiDi;
    • via DLNA;
    • using a special program.
    READ  Smart TV Does Not Catch Wi-Fi

    Adapters for older models

    Consider whether it is possible to send an image to a TV, where Wi-Fi is completely absent as such. This question worries almost every owner of an old TV, because models with Wi-Fi are not cheap, and not everyone wants to buy a new TV. But here it should be understood that if there is no special module on the TV, then it is still possible to connect to a laptop via Wi-Fi. If your existing TV was released more than 5 years ago, then you will need to purchase additional devices to make the connection, which is discussed in the article.

    These are special adapters that are usually plugged into an HDMI type port.

    If we talk about such devices, then they exist of 4 types:

    • adapter type Miracast;
    • Android Mini PC;
    • Google Chromecast;
    • Compute Stick.

    Each of these types of adapters can be connected to a not too old TV model and will allow you to connect a laptop using Wi-Fi.

    With the help of special software

    It should be noted that there is also a special software that makes it possible to combine devices and control the TV from a laptop. This is the so-called home server, which makes it possible to make Wi-Fi connection of the mentioned devices. The main advantage of this solution is its versatility.

    First you need to download the selected software, install it and run it. After that, you will be able to see a list of devices that are available for connection. You need to find your TV in it. After that, the program will give the TV access to the standard media directories on the laptop. And by clicking on the green plus icon, you can “share” several files so that they become available for playback on TV.

    Now I would like to say about several of the most popular programs of this type. One of them is a program called Share Manager. It is only suitable for those users who have a Samsung TV. This software is a solution for models that support DLNA technology. Instructions for using this program are as follows:

    • TV and laptop should be connected to the same Wi-Fi network;
    • after that you need to download the program and launch it;
    • open it and find an analogue of Windows Explorer;
    • find the folders you want to play;
    • drag the required files to the right side of the window;
    • click on the item “Sharing”, then select the phrase “Set device policy”;
    • now you need to launch the list with available devices and press the OK button;
    • in the general access, you should find the item “Changed state”;
    • when the update happens, you need to look at the signal sources on the TV;
    • in the corresponding menu, click Share Manager and find the Share Folder;
    • after that you will be able to see the files, as well as the necessary folders.

    Another program that deserves attention is called Serviio. It is free and designed to create a DLNA channel.

    It is extremely easy to use and even an inexperienced user can do it.

    Among the features of this software are:

    • the library with files is updated automatically;
    • you can simply create a home network;
    • video streaming is possible on a wide variety of devices.

    True, this program puts forward certain requirements for a laptop:

    • RAM in it must be at least 512 megabytes;
    • the hard drive must have 150 megabytes of free space for installation;
    • the device must be running Linux, OSX or Windows.

    What is it for?

    First of all, as already mentioned, watching a movie on a TV screen with a larger diagonal will, of course, be much more interesting. And any video on such a screen will look much better and more colorful than on a computer monitor. And if we are talking about content with a resolution of 4K, then given that a large number of TV models have just such a resolution, it will be possible to enjoy it to the fullest.

    Viewing family photos and snapshots will also be relevant for such devices. And you can transfer an image from a laptop to a TV in just a couple of clicks. Plus, sometimes TVs come with really cool speakers that deliver great sound. So it’s not a bad idea to connect your laptop to your TV over Wi-Fi to stream music.

    How to connect a laptop to a TV via Wi-Fi?

    Nowadays, in almost every home you can find a fairly powerful computer or laptop, as well as a flat TV with support for Smart TV or with an Android-based set-top box. Considering that the screens of such TVs have a diagonal of 32 to 65 inches or more, you often want to watch a movie from your computer on the TV. Let’s try to figure out how to connect a laptop to a TV via Wi-Fi, and consider the technical features of this process.

    Via WiDi

    Another method that allows you to connect a laptop to a TV is called WiDi Miracast. The essence of this technology will not be the same as that of DLNA, which consists in the so-called “sharing” of folders and setting up shared access to them. WiDi makes it possible to duplicate the image from the laptop display to TV. That is, in fact, we have before us a projection of the image. The implementation of this solution is also based on the use of Wi-Fi technology. A number of users call it Miracast.

    This connection method has some technological features. The point is that a laptop can use this technology if it meets 3 criteria:

    • it has a Wi-Fi adapter;
    • it is equipped with a discrete type video card;
    • the central processing unit, which is installed in it, must be manufactured by Intel.

    And some manufacturers make it so that a laptop can be connected to a TV via Wi-Fi only using this technology. For example, this is what the South Korean company Samsung does.

    Before you start setting up the connection, you must first download the drivers for the laptop for the wireless display. They can be found on the official Intel website. You should also make sure that your TV model is WiDi compatible. Older devices cannot boast of support for this technology, which is why users often have to buy special adapters. In general, this point should also be clarified.

    If, nevertheless, it turned out that both the laptop and the TV support WiDi, then you can proceed to setting it up. The algorithm will be as follows:

    • we enter the main menu of the TV;
    • go to the “Network” section;
    • select and click on the item called “Miracast / Intel’s WiDi”;
    • now you need to move the lever that will enable this setting;
    • we enter the Intel Wireless Display program on a laptop, which is responsible for wireless synchronization with television equipment;
    • the screen will show a list of devices available for connection;
    • now you need to click on the “Connect” button, which is located next to the name of the TV.

    In some cases, it happens that an additional PIN code is required. Usually his combinations are either 0000 or 1111.

    To complete the configuration of WiDi technology, you must click on the item called “Charms” and enter the corresponding section. Here we find the item “Devices”, and then the projector. Add your TV screen here. If for some reason the required device is not here, then you need to install the latest drivers for the Wi-Fi module. In this simple way, you can connect a laptop and TV.

    HDMI connection

    The HDMI interface is one of the most common means of communication for digital devices today. With the help of it, sound and video can be transmitted in high quality and with minimal loss. Almost all modern laptop and TV models are equipped with HDMI connectors. Other interfaces. VGA, DVI, Scart. are also widely used, but inputs / outputs of such formats are not available on all devices. For example, you are almost guaranteed to find the same DVI on any video card or monitor, but it is often absent on laptops and TVs. Also, some TVs may not have a VGA connector, although it is mandatory on laptops.

    READ  How to turn on the TV without a remote control and buttons

    Let’s say right away that there is not much difference with which wire to connect the laptop to the TV. Whether it’s HDMI, VGA or DVI, the sequence of steps and the final result don’t differ much. The only thing that Honor needs is that the DVI and VGA interfaces are only capable of transmitting video signal, so the sound will have to be connected using a separate audio cable.

    Connecting wires and setting up the TV

    So, let’s begin. We will connect an HP laptop with Windows 10 preinstalled to an LG TV running webOS. This is what the HDMI connectors look like:

    For connection, we use an HDMI cable 5 meters long. His photo is shown below.

    We connect with the equipment turned off. We plug one end of the cable into the laptop connector, the other into the HDMI 2 connector of the TV.

    We turn on both devices and wait for Windows to load on the laptop. As for the TV, while it is broadcasting the TV program (the antenna cable has not been disconnected). We take in hand the television remote control and find the control button for signal sources. It is usually called Source or Input.

    We press it and in the menu that appears on the TV screen, select HDMI-2.

    After some thought, the TV should display the laptop desktop.

    In our case, it slightly went beyond the boundaries of the TV screen. To fix the problem, it was necessary to go to the Settings on the TV (Settings button), then select the “Screen” item and set the “Screen Format” as “Initial”.

    The image now fits perfectly within the boundaries of the TV screen.

    Setting up displays in Windows 10

    We click on the desktop with the right mouse button and in the context menu select the item “Display settings”. The displays can be configured directly on the page that opens, or by going to the advanced settings using the link “Additional display settings”.

    In the drop-down menu, there are several options for how the displays work: “Duplicate these screens”, “Extend these screens”, “Show only by 1”, “Show only by 2”.

    By default, duplicate mode is active. This means that the same is displayed on both laptop and TV screens. The second option provides for the ability to transfer working windows of programs between displays and broadcast on each of them your information. The purpose of the last two modes is clear. the picture will be displayed only on one of the two screens, the second will turn off.

    Here, in the Parameters, it is possible to set the screen resolution and make some other settings.

    We will not focus on them, everyone will be able to experiment on their own and adjust everything for themselves. We completed the main task. connected the laptop to the TV via an HDMI cable.

    Setting up displays in Windows 7

    The above information on configuring displays is relevant for Windows 10, where display settings are made through the Settings utility. In Windows 7, all actions are performed in the Control Panel, although the essence remains the same. Let’s go to the desired configuration page by right-clicking on the desktop and selecting “Screen Resolution”.

    The interface of the settings page will be slightly different than in Windows 10, but the meaning remains the same, so it’s easy to figure it out.

    The HDMI interface allows you to transfer not only video, but also sound. However, it may happen that you have connected and configured everything seems to be correct, but the sound on the speakers built into the TV is not reproduced. To eliminate this problem, go to the Control Panel. Sound. On the “Playback” tab, the TV should be selected as the default device, in our case LG TV.

    If the device is turned off, then you need to turn it on. If it is not displayed at all, then right-click on the window and check the “Show disconnected device” checkbox. Next, turn it on and everything should work fine.

    We connect the laptop to the TV via HDMI and Wi-Fi

    Probably, many laptop owners have a desire to display the image from their laptop on a display with a large size and resolution. Such a screen is better suited for viewing high quality photos and videos, and the graphics of modern games will look more beautiful and realistic on it. The most obvious and simple solution to the issue is to connect a monitor from a stationary computer to a laptop. However, all the latest TV models that run their own operating systems also provide the ability to interface with a PC. In this article, we will just tell you how you can connect a laptop to a TV wired and without using wires (via Wi-Fi). Note that we are not talking about a simple broadcast of video and photos from a laptop on the TV, but about a full duplication of the desktop and all Windows functionality, i.e. using the TV as another monitor.

    Using Wi-Fi

    Let’s consider another way to connect a laptop to a TV, this time wirelessly using WiDi technology and a Wi-Fi network. Let’s make a reservation right away that this method is only suitable for laptop computers assembled on the basis of Intel components. Plus, WiDi technology must be supported by your TV. Be sure to install the latest firmware on your TV, as older software versions may not provide WiDi connectivity.

    Before proceeding directly to configuring the wireless connection between the laptop and the TV, you need to make sure that both devices are connected to the same Wi-Fi network (one router). For LG, to check the connection, go through the settings menu to the “Network” section.

    If the TV has not previously been connected to Wi-Fi, you need to set up the connection. There should be no problems with a laptop.

    Each TV model will have a different location for the WiDi toolkit. LG has the following steps to access it:

    Now the TV is ready to connect the laptop, all that remains is to perform the necessary actions in the Windows 10 interface.

    We go through the Parameters utility to the “Screen” section and click on the link “Connect to a wireless display”.

    A panel will appear on the right, on which, after a few seconds of searching, the TV should be displayed, in our case LG webOS TV.

    Click on it to start the connection and wait for the procedure to end. If everything goes well, the message “Connected” will appear on the panel under the name of the wireless display.

    The TV will display the Windows desktop of the laptop.

    By the way, the projection mode can also be changed, as we did when connecting devices with an HDMI cable.

    connect, laptop, wi-fi

    In principle, the goal is achieved, it remains only to check if the sound works.

    Finally, we note that if you want to connect your laptop to the TV in the most reliable and stable way, then, of course, it is better to use an HDMI cable. Wireless connections are prone to interruptions, and image transmission may experience delays, especially in games.
