Such actions are possible, but the signal is often unstable, can be interrupted, and this creates inconvenience. Ideally, this connection is best used for listening to music, viewing photos, or.

In this article, we will look at how to connect a laptop to a TV via Wi-Fi in various ways, depending on the available wireless signal transmission technology.

DLNA connection

This is the most common common type of wireless connection available for almost all modern TVs. The only condition is that they have a built-in Wi-Fi module. Although sometimes you can do without it, which will be discussed below.

The main disadvantage of connecting using this technology is that it is not suitable for displaying a desktop image or a computer game from a laptop to a TV in real time, since it does not provide synchronization of actions. Available only for viewing photos, or listening to music, which are pre-loaded into the TV’s memory.

WiDi connection

Wireless Display (WiDi) or Miracast is available on most modern Smart TVs and laptops with integrated Intel 3rd generation or higher. However, full support for this technology is guaranteed on Intel branded laptops with Windows 8.1 or Windows 10 preinstalled. For earlier editions (Windows 7/8), additional drivers may be required, which can be found on the Intel website.

The convenience of WiDi technology lies in the fact that all actions on the laptop are synchronized with the TV, which actually acts as a second display. Therefore, such a connection is suitable for computer games, surfing the Internet and other streaming activities.

Establishing a wireless connection in this case is quite SIMple:


Enter the TV settings with the MENU button on the remote and in the “Network” section turn on the WiDi function. In the Russian-language menu, it can be called differently: “Screen mirroring”, “Screen mirroring”, etc.

If you did not find such inscriptions among the menu items, but the WiDi technology is declared in the instructions for your TV, then it is SIMply turned on by default (which usually happens), and you just need to activate the Wi-Fi module.

Launch Intel Wireless Display on your laptop and enable search. After finding the desired device to connect to it, you may need to enter a confirmation code, which is displayed in the TV settings when the WiDi function is turned on.

To activate Miracast in Windows 8.1 on a laptop, enter the Charms bar, where select “Devices”. “Projector” and add the TV as a wireless display. Or “Connected Devices”. “Add Device” in Windows 10.

Connecting with an adapter

This function is convenient for TVs that do not have a built-in Wi-Fi module, but have HDMI or USB ports. In this case, you need to purchase a special adapter that installs a virtual operating network on the TV and makes it possible to use almost all modern wireless Smart TV technologies, including Miracast.

As a rule, such adapters are plug and play devices, that is, all the necessary drivers are located on the device itself and are automatically activated when connected to a TV. Further, the setting takes place in the ways described above.
