How to Stream Video From Laptop To TV

The laptop is very convenient for working with its dimensions and light weight. But when it comes to watching videos or games, you want to replace a small monitor with a larger screen. If you have a TV with a large diagonal, you can connect your device to a TV or home theater. In the article, we will consider how to display an image on a TV from a laptop.

Identify available connections

To transfer images from a laptop to a TV, you need to find out what methods are available for this. First you need to look at which ports are present on the TV and laptop, and then decide how best to duplicate the laptop screen.

Ways to output images from laptop to TV

There are wireless and wired methods for outputting images from a laptop to a TV. A wired connection does not have to have the same ports on both devices. If they are different, then it will be necessary to use adapters. If you need to translate digital data to an analog input, you will need additional converters or consoles.

The disadvantages of a wireless connection are limited bandwidth and possible signal interruption. The disadvantage of connecting the cord may be the presence of the cord itself, as well as the cable length limit for different standards. However, if you want to connect a laptop and enjoy watching, this drawback is completely weightless and will not cause inconvenience.

All modern televisions are equipped with DLNA technology, which allows devices to exchange data within the home network. This can be done both by cable and WI-FI. If there is a connection via WI-FI, then both the laptop and the TV must be connected to it. But the TV will only “see” shared folders. In order for the TV to be available all the information, you can in the settings “Network” On a laptop, share all folders. But this is not recommended for security reasons. Indeed, in this case, everyone who will be connected to your network will be able to use your data. Another option is to make the specific folder public.

But for more convenient displaying images on a TV, it is better to download the program. One of the recommended ones is Home Media Server. It is free and universal for different TV models, and also has wide functionality. To install on a laptop, just download the application (preferably on the official website) and run the installation file. After starting the program, in the settings window, you can select the category of media resources and specify access to folders there.

If your devices support Miracast or Intel WiDi technology, then just turn on these features on the TV. Then he will be able to connect wirelessly to your laptop without a router, directly. On the laptop, however, you will need to put the appropriate application. But when connected, you can display any picture from a laptop.

If the TV does not have a WI-FI module, then you can use various adapters that can be connected to the HDMI port. For example, one of these devices is Google Chromecast, which looks like a USB flash drive. The gadget is designed to stream multimedia content.

A connection via HDMI can be called optimal in order to transfer media from one technology to another. This standard provides high-speed transmission, even of files in ultra HD quality, and not only transmits video, but also multi-channel sound.

How to output an image from a computer to a TV using HDMI? It is enough to connect the two devices with a cable. Then switch to TV AVI mode and select the port to which the cord is connected. On the laptop, you need to call up the screen settings and set the required resolution there, as well as select the display of the displays. This means that on a laptop you can control both screens, and you will need to select a display for the TV screen. The options are:

  • Duplication. the same image on both screens;
  • Display on 1 screen. the second will turn off;
  • Screen Extensions. TV will become the second monitor.

Settings may vary depending on the version of the operating system.

For any wired connection, devices must be disconnected before connecting.

The next way to transfer the image via DVI. The DVI standard was developed for transferring video content to digital devices. It is the predecessor of HDMI. And, unlike the latter, it does not transmit sound. In this case, you will need a TRS connector or adapter, otherwise called a “mini-jack”. a very popular audio jack, probably familiar to many as an input for connecting headphones. To duplicate the screen of a computer or laptop, you will need to perform the same steps as for HDMI. After connecting, transferring the playback file is not difficult.


S-Video is an analogue interface. It can only transmit video files of standard definition television (576i and 480i), which means that there can’t be any talk about modern quality formats. Televisions are rarely equipped with such a port, so in order to project an image from a laptop, you will additionally need an adapter from S-Video to RCA. Also, do not use an S-Video cable more than 2 meters, as this will lead to a deterioration in signal quality. To transfer sound to a TV, similar to DVI, you will need to use a “mini-jack”.

After connecting the cable, you always need to set the video source on the TV

Consider how you can display the image on the TV via USB. In this case, when connecting a USB-USB, it will be impossible to view the video, since this standard is not designed to transmit video data. In this option, you can view images, presentations, text documents. With this connection, the TV will see the laptop as a USB flash drive.

But to duplicate the laptop display, you can use the output to the HDMI port of the TV. To do this, you need an adapter, which is an external video card. You will need to install the driver from the video card to the laptop. When purchasing such an adapter, you should pay attention to the characteristics of the transmitted video (support Full HD) and sound.

Wireless LAN connection we have already covered. Lan is a network but wired (Ethernet) connection. If the TV does not have a Wi-Fi module, then you can use this method. To duplicate a computer screen on a TV, you will need to perform the same steps as for a WI – FI connection. Namely:

  • Connect the TV to the router using a network cable. At the same time, the DHCP host dynamic protocol must be configured on the network device. Otherwise, you will have to register the network settings manually in the TV;
  • Connect the laptop to the same network. Wired or wireless. it does not matter;
  • Install the program on a laptop to display files on TV. Already reviewed application Home Media Server, which is easy to configure and install;
  • Share the required folders. That’s it, now you can transfer images and send to play video.

How is it possible to transfer an image from a computer to a TV using VGA? The VGA standard allows only analog signal to be transmitted without sound. To play the sound you will need an additional adapter with the so-called “tulips” or a plug “minijack”. Another option is to leave the sound playing on the laptop or through the speakers connected to it. For this, you can use the laptop function keys. It should display 2 screens, for example, F10 Fn (function enable key). Now it is possible to display video from a laptop on a TV. When setting up a display on a laptop, you can increase the resolution to get a better picture.

Any cable connection will have to configure screens on a laptop or PC

A color image is formed by three main signals: Red, Green, Blue. If the image is output from such a connector, then it is logical to use the same TV input. RGB replaced Scart when scarts became impossible to use on thin TVs. Basically, RGB is available on older models. Compatible with Scart and composite RCA (“tulips”) cable. Video or games from the computer monitor to the TV will be broadcast, as with any other cable connection.


Scart is the European standard for transmitting analog and digital signals. It has different specifications, respectively, it can transmit different signals (sound channel, video, control). The convenience of the interface is that it makes it possible to connect a high-quality RGB video source to the TV without intermediate coding.

To broadcast a movie from a PC or laptop, it is better to use the VGA-SCART adapter. This is due to the fact that a large number of TVs are equipped with a SCART connector, and computers. VGA.

Wired connection in the presence of a large number of connectors is better to choose from the latest technologies. The best option is HDMI. In general, setting up a laptop and TV is straightforward. The main thing is to choose the input signal on the TV, and on the laptop to perform the settings that are required for the corresponding technology.
