How to connect a TV to a computer

Watch your favorite movie on the “big screen”, play a game so that everyone enjoys contemplation, well, or just watch some video, photographs or something else – this may be necessary to connect the TV to the computer.

Modern technologies allow you to use the TV to view photos and videos encoded in almost any way, many of them even allow you to go online or play simple games without the help of consoles, but, of course, not everyone can afford a new TV – however, even this In this case, you can still connect your TV through a computer!

Depending on the country in which the TV was manufactured and at what time, the input connectors for receiving a signal on it may be different. The standards for image and sound transmission do not stand still, and we will try to cover those that have been used or are still being used and involve the use of a TV as a means of outputting information from a third-party source (in our case, from a computer).

One of the first standardized connectors used to transmit video and audio signals is SCART. Recently, it has been almost impossible to meet him on new televisions, but old European-made TVs and some models of Japanese TVs intended for sale in other countries were equipped with it. The connector has a large number of contacts, which allows you to transmit both video and audio in a two-channel format. Below you can see what the SCART connector looks like.

However, the bulky dimensions of the connector, sensitivity to noise and interference, some problems associated with damaged contacts – all this makes the use of SCART adapters not the most convenient, but if there is no way out, then you can use one of the many adapters. In this case, the video signal can be received from various sources.

If, for example, your video card has an S-Video connector, then you can use special adapter cables that allow you to use this connector with SCART. At various times, video cards were equipped with two types of these sockets, with four and seven contacts. The analog nature of the signal gives minimal distortion when outputting to a TV, however, the output of the audio signal will have to be done separately. Below you can see the S-Video connector for connecting to a video card.

To output the sound signal, you can use the RCA-connectors, known to everyone “tulips”. Due to the widespread use of SCART adapters with an RCA input, the use of tulips and the corresponding S-Video splitter adapter may be almost the only option, since these parts of the circuit can still be found on sale. A picture of tulips or RCA connectors is located below.

In addition, for capturing sound, you can use RST connectors of various form factors, especially since there are a fairly large number of different adapter devices for them. I will not give a photo of the RST connectors, as There are a lot of formats of this connector, and at any electronic point on the market you can consult these sellers.

The basic rule to follow is to achieve the “same” connectors on both sides, that is, both on the computer and on the TV. Once you succeed, you can use the highest quality cable that you can find – this minimizes the loss of image and sound quality during transmission.

The above standards are used to transmit an analog signal. Due to physical limitations on the output, you can get a picture of not the highest quality, so if you have a more or less modern computer with a good graphics card, it is best to use a digital transmission channel.

The “first sign” in this direction was the invention of the DVI connector. It allowed transmitting video in digital format over considerable distances with virtually no loss, which was actively used for projectors (in addition, a VGA format having an analog-digital nature was also used there). There are several transmission standards in this format, they differ in the transmission channel bandwidth. In the photo below, I showed a DVI format connector.

And in the image below you see a classic photo of VGA connectors.

However, DVI also had some limitations – the standard did not imply the transmission of audio information in either analog or digital form. It was assumed that there was a common audio system that took care of the audio processing. However, this was far from always convenient and a new format was developed, which allows transmitting both an audio signal and video. It is he who is considered the standard for digital media transmission in the modern world.
