How to connect a TV to a computer or laptop via Wi-Fi: mirroring screens

Many users prefer to watch video production on large screens rather than on computer monitors. Thanks to wireless communication and special programs, your TV can, if necessary, act as a large display, working in conjunction with a computer via Wi-Fi.

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

The TV is connected to the computer not only by various wired methods, but also via Wi-Fi. The signal source can be either a stationary computer or a laptop. The screen can be used to view videos and audio recordings from the hard drive.
connect the TV to the computer via Wi-FiAlmost all the methods used to connect the TV to Wi-Fi require that it has support for wireless communication. That is, the TV must have a Wi-Fi adapter. Most modern TV devices have a similar device.

How to transfer picture and video from computer to TV via Wi-Fi (DLNA)

This method of wirelessly connecting TVs is considered the most common. This and all subsequent instructions are written for the operating systems Windows 7, 8.1 and Windows 10 TV requirements:

  • the presence of a Wi-Fi block;
  • the TV is connected to a router, from which computer equipment works with video and audio materials.

If your TV supports Wi-Fi Direct, you don’t need a router – you can connect directly to your TV network. To make a connection, you need to go to the corresponding TV menu. The DLNA function can be used to play content without setting up a DLNA server. Condition – the computer and the TV must be in the same local network – connected to the same router or via Wi-Fi Direct. Procedure:

  1. Configure DLNA server on your computer . You need to open access to the files you want. To do this, select the “Home” type in the network settings. All other folders – with documents, images, music and videos become available by default. To open access to a specific folder, just right-click on it. Select the Properties and Access tabs from the context menu.
  2. Turn on sharing . The fastest option is to open File Explorer and select Network. If you are then informed that network discovery and access are disabled, click the message and follow the instructions that appear.

Configuring Windows Access:
Access settingsIf this message does not appear and computers and media servers appear instead, it is likely DLNA is already configured. Otherwise, you will have to configure the DLNA server. When DLNA is configured and connected, open the TV menu and see what devices are connected. The algorithm of actions depends on the brand of the TV, for example:

  • in Sony Bravia, press the Home button, and then, selecting the desired section – Music, Movies, Pictures, view the contents of your computer;
  • in LG, select SmartShare , there you will see what is in the folders, even if you do not have this program on your computer.

In TVs of other brands, you have to perform approximately the same manipulations using the appropriate programs. Accessing files via Wi-Fi DLNA on TV:
Access to filesWhen DLNA is connected, go to the desired folder on your computer and click on the video file in the explorer, select “Play on ….”. The dots will be replaced by the name of your TV. Then the video signal transmission via Wi-Fi will start – from the computer / laptop to the TV.

Even if the TV has support for MKV movies, “Play To” does not work for them in Windows 7 and 8, so they will not be visible in the TV menu, the easiest way to fix the problem is to rename these files to AVI on your computer.

TV as a wireless display (WiDi)

We figured out how to play computer files on a TV screen, and how to make them available. Next, we will learn how to watch any picture from a computer / laptop on TV. The TV will act as a wireless monitor. To accomplish the task, they use one of two technologies – Intel WiD or Miracast. The connection does not require a router, since a direct connection is established using Wi-Fi Direct. What you need to know about your computer:

  1. If your computer has a 3rd generation Intel processor , it has an Intel wireless adapter with an integrated Intel HD Graphics chip, then it supports Intel WiDi in Windows 7 and 8.1. You may need to download Intel Wireless Display. You can download the program on the official Intel website .
  2. If Windows 8.1 was preinstalled on the computer / laptop and there is a Wi-Fi adapter, then Miracast must be supported. When installing Windows on your own, there can be any option – with or without support. Earlier versions of the operating system – up to 8.1, do not support Miracast.

Support from TV is required to use Miracast. A couple of years ago, you would have had to buy a special adapter, but today many TVs are released with built-in support for Miracast technology, or receive it after a flashing.

Miracast on TV:
MiracastConnection process:

  1. Turn on WiDi or Miracast support on your TV. It usually works by default. It happens that the TV does not have such a setting at all, then it is enough to turn on the Wi-Fi module. In “Samsung”, for example, this function was called “Screen Mirroring”, it is located in the network settings.
  2. Turn on WiDi by launching Intel Wireless Display and select a wireless monitor. You may be asked for a code – it will appear on the TV screen. Looking for a WiDi wireless monitor:Enable
  3. To enable Miracast in Windows 8.1, open Charms – this panel is on the right. Click successively the “Devices” and “Projector” tabs. Then click on the Add Wireless Display label.Add display

If this item is not present, it means that your computer does not support Miracast technology, in order to correct the situation, you will have to update the Wi-Fi adapter drivers.

Connecting laptop to smart TV via WiFi wirelessly

Most televisions today are equipped with a function that makes interactive content available to them. You can display movies, music, games and more on the TV screen. This technology is called
Smart TV . “Smart” is implemented in Samsung TVs, similar technologies are available from other manufacturers – “Sony”, “Philips”, “Panasonic” and others. Let’s take a closer look at the procedure for connecting a TV with Smart technology to a regular laptop via Wi-Fi. Procedure:

  1. Connect your laptop and TV to the same Wi-Fi network . If the computer equipment is already connected to the router, it remains to do the same for the TV. Turn on the TV and use the remote control to enter its “Settings”, and then to the “Network” tab.
  2. Turn on the Wi-Fi adapter . Select the laptop connection point from the list. Both devices are now connected to the same local network.
  3. Configure DLNA Server . Open on your laptop access to folders containing videos and other content. This is done in the “Network Control Center”. Go to the “View active networks” section and change the shared network to the local one. DLNA Server Setting:Server Tuning

  4. After enabling DLNA, take the remote control and find the section on viewing content on your computer in the menu . For example, on Sony TVs this item is called “Home”, in LG – “SmartShare”.

Selecting content from a computer:
Content selectionIf all settings are made correctly, you will include video from a laptop in two clicks:

  1. Having highlighted the file you like in the laptop, right-click on it and select “Play on …” from the menu.
  2. Find your TV model in the list of devices. Click on it and the video file will be broadcast to the screen.

Wi-Fi connection of a regular TV without a wireless adapter via HDMI input

If you haven’t gotten a modern Smart TV, nothing is lost. A simple TV can also be used to solve the problem. The main thing is that the device has an HDMI input. To achieve this goal, you will need one of the following devices:

  • Google Chromecast. This little gadget is called a digital or network media player. These are Google products. The device is designed to transfer video and audio files via Wi-Fi from the Internet or a local network. What Google Chromecast looks like:Google chromecast
  • Android Mini PC. It looks like a USB flash drive. Connects via HDMI port to the TV.
  • Intel Compute Stick. The device is about the size of a package of chewing gum and can turn any monitor with HDMI input into a full-fledged computer with high-quality graphics and wireless connectivity. This compact computer measures 11.5 cm. Notebooks have many synchronization options besides the above algorithm. You can duplicate the image – the same picture will be on two screens. If you make one screen the main one, then the second one will automatically turn off. Instead of a laptop or computer, you can use a smartphone. This makes screen management even more convenient. Modern TVs can be used to access the Internet, while they do not lose their main function – they play video on a large screen. How to connect a TV to a computer via wifi:

    Мы тоже недавно купили телевизор с вай-фай, так как смотреть по интернет все фильмы и программы намного удобнее и интереснее. Мы выбрали LG со встроенным адаптером, поэтому все настроить было относительно несложно. Правда, так как мы не очень уверенные пользователи, то повозиться все-таки пришлось. Здесь все рассказало по каждому вопросу и расписано понятно, а вот мы по самой инструкции к телевизору разбирались методом “тыка”, нужно было попросить детей, они там все знают. С вашими инструкциями все проще бы было.

    Недавно как раз столкнулись с проблемой подключения ноутбука к телевизору через wi-fi, никак не могли понять, что делаем не так. Хорошо, что наткнулась на эту статью. Расширили доступ к файлам и всё заработало! Спасибо, не пришлось тратить деньги на вызов мастера!

  4. Ирина

    Искала информацию как подключить телевизор к компьютеру через Wi-Fi на даче. Вызывать мастера не хотела, решила сама подключить. Много что читала в интернете, и эта статья оказалась самой полезной и понятной. Я как новичок в этом деле разобралась без проблем, подключила самостоятельно.

    Недавно, из-за сломавшегося телевизора “не SmarTV”, пришлось покупать новый, на наш взгляд упала модель LG SmartTv 4k, только ничего в этом не разбирались, спустя время, осознали в какой-то мере, как пользоваться данным устройством, и задались вопросом просмотра фильма, а так как фильм уже был скачан на компьютер, не понимали, как же все таки это сделать, но благодаря данной статье, удалось разобраться и подключиться, спасибо большое, если есть, те у кого не получилось, то скорее всего, вы не делали все по инструкции
