Where is the dvi d connector used? Interfaces. DVI and HDMI. When you need a good picture

Currently, there are a huge number of different video standards and interfaces. Some have been in use for more than a decade, others are just entering our everyday life, and it’s quite easy to get confused in this variety. This is as difficult as for a non-specialist to understand a template for a forum. In this article we have made a small selection of various interfaces for transmitting video signals, as well as common video connectors.

We hope you find this information useful.

Composite video output

Composite video output is designed to transmit all components of a video signal in a mixed form over one wire.

Typically the composite connector is a yellow RCA jack, or a generic SCART connector. To transmit a composite video signal, a coaxial cable with RCA ("tulip") connectors at the ends is used.

Composite video signal ( composite video) has been used since the reign of video cassettes, but is not capable of transmitting a high-quality signal. For this reason, it is currently used only in inexpensive video equipment, for example, in televisions with a small screen diagonal (14"-21").

Component video output

Component video is also called color difference video. It contains a luminance signal (Y) and two chrominance signals (U and V), which are determined by the formula:

Y = 0.299R + 0.587G + 0.114B

Interlaced ( interlaced) or progressive ( progressive) sweep. Interlace scanning is used in all existing television broadcasting systems. Progressive scanning is used in the modern television standard HDTV and in modern DVD players, as it allows for higher image quality.

To transmit such a video signal, three separate coaxial cables are used, at the ends of which there are RCA ("tulip") connectors or BNC connectors.

Video output S-Video

The S-Video connector is commonly used to output video signals from camcorders, PCs, and game consoles to household televisions and other consumer video equipment. The S-Video interface uses two signal lines - a chrominance (C) signal and a luminance (Y) signal. When used as a signal source from a DVD player or a satellite receiver and a TV with a diagonal of 25" or more, this interface allows you to obtain a higher quality image than a composite video signal.

The cable for transmitting this video signal contains different types of connectors: 2 BNC connectors, 2 RCA connectors, 4-pin Mini DIN connector or a universal SCART connector.

RGB video output

To transmit a color image to a CRT monitor, intensity signals for each RGB color, as well as horizontal (H) and vertical (V) scan signals, are used. A total of five signals are obtained - RGBHV.

To transmit the RGB signal, 5 coaxial cables equipped with BNC connectors are used.

VGA video output

In addition to RGB and synchronization signals, the VGA connector also contains so-called DDC signals for transmitting information between the video card and the monitor. The VGA cable connects using a 15-pin D-Sub connector (also called D-Sub 15 pin).

DVI video output

DVI digital video output is used mainly in video adapters of personal computers. It provides digital signal transmission directly from the video adapter of a computer or laptop to the projector. This does not use an intermediate digital-analog image (as in the S-Video standard or in a composite video signal), which allows you to obtain a higher quality picture.

Today there are two types of DVI connectors:

  • universal combination connector DVI-I. It allows you to connect both digital and analog monitors (with an adapter from DVI-I to 15-pin VGA D-Sub);
  • fully digital connector DVI-D, to which only digital monitors can be connected. This connector differs from the DVD-I connector in that it does not have four holes (pins) around the horizontal slot. As a rule, such an interface is used only in cheap video cards.

In addition, DVI connectors (DVI-I and DVI-D) have two types of connector: Single Link And Dual Link, differing in the number of contacts. At the same time, Dual Link uses all 24 digital contacts, while Single Link uses only 18. Single Link is used in devices with a resolution of up to 1920x1080 (the so-called HDTV). For higher resolutions, Dual Link is used, which allows doubling the number of output pixels.

HDMI video output

HDMI interface ( High Definition Multimedia Interface) is designed for connection to DVD players, satellite receivers and video adapters of personal computers, modern televisions and home theaters. Today it is the standard for transmitting digital audio and video in uncompressed form.

HDMI is an all-digital digital format that allows you to transmit not only high-definition video, but also many digital audio channels using just one cable. An HDMI cable with a signal spectrum width of up to 10 Gbps allows you not only to output high-resolution video, but also simultaneously transmit up to eight channels of high-quality audio.

The HDMI interface is a further development of the DVI-D interface and is fully compatible with it, but has more advanced parameters.

Currently, the following types of HDMI connectors are available:

  • Type A, which has 19 contacts and is most widespread.
  • Type B, having 29 contacts. It has an extended video channel, which allows you to transmit video information with a resolution higher than 1080p. Currently, this connector is not yet in great demand.
  • mini HDMI is designed for use in camcorders and portable devices. It is a variation of the HDMI Type A connector, but has a reduced size.

Please note that the HDMI cable cannot be longer than 15 m.

If we arrange all the video standards described above in increasing order of video signal quality, we get:

  • composite video
  • S-Video
  • component video

The digital DVI interface replaces the analogue VGA interface used in most older monitors, which has existed unchanged for over a decade. The need for such an “upgrade” has been brewing for a long time: the analogue method of data transmission had many disadvantages, first of all, significant restrictions on the amount of transmitted information, and therefore on the maximum resolution that the monitor can support.

The first versions of DVI were based on a serial data format and used three channels carrying video and additional data streams, with a throughput of up to 3.4 Gbit/s per channel.

At the same time, increasing the cable length had a negative impact on the maximum permissible volume of transmitted data. Thus, a cable 10.5 m long can be used to transmit an image with a resolution of up to 1920 × 1200 pixels, and if its length is increased to 15 meters, then it is unlikely that it will be possible to transmit an image more than 1280 × 1024 pixels without loss of quality (in extreme cases you will have to use several cables and special signal amplifiers). To ensure compatibility, several types of DVI cables have been developed, differing not only in their characteristics, but also in their connectors. By looking at the connector, you can understand what characteristics the cable has - namely, what data it can transmit and in what volume.

The simplest option is DVI-A Single Link. The letter A in this abbreviation means “analog”. Such a cable is not capable of transmitting digital data at all, and, in fact, is an ordinary VGA cable equipped with a DVI connector. It is quite difficult to find such a cable in real life.

DVI-I cables support both analog and digital data transfer. This cable is one of the most common: the letter “I” in the abbreviation stands for “integrated”, and means that this cable has two independent data transmission channels - analog and digital. Using such a cable, you can connect both a digital monitor and an analog one (for example, an old CRT monitor). To do this, you will need an inexpensive DVI-VGA adapter.

Finally, DVI-D cables only support digital data transfer. You won't be able to connect an old analog monitor to them. In particular, you need to remember this when choosing a video card: by looking at the connectors available on it, it will become clear which monitors can be connected to it and which cannot.

The DVI-I connector has more pins than the DVI-D connector. Additional contacts on the DVI-I connector are responsible for transmitting a signal in an analog format, which is not available on the DVI-D connector.

Finally, we need to talk about the Dual link variation (dual mode), which is found in DVI-I and DVI-D cables. The DVI standard implies the ability to double the channel bandwidth by adding several additional pins to the connector.

Thanks to this, the cable can transmit twice as much information, and therefore the monitor can be set to a higher resolution and refresh rate. Without Dual Link, nVidia 3D Vision three-dimensional image display technology will also not work, for the implementation of which you must have a refresh rate of 120 Hz and a resolution of 1920x1080.

If we take the standard screen refresh rate of 60 Hz, then the Single Link cable will provide a resolution of up to 1920x1080 pixels, and the Dual link will allow you to transmit an image in a resolution of up to 2560x1600 pixels.

The conclusion that can be drawn from these figures is clear: to connect digital monitors with a relatively low resolution by today's standards, any digital DVI cable is suitable - in this case, a Dual link is not required. If the monitor supports resolutions such as 2048x1536, 2560x1080 or 2560x1600 pixels, then dual mode will be indispensable.

If the house has an old monitor with an analog VGA connector, but the video card does not have such a connector, you will have to make sure not only that there is an adapter, but also that the cable supports analog data transfer (that is, it is equipped with a DVI-connector). I).

We select the required plug for the appropriate connector. What types of cables do manufacturers offer? "HDMI,DVI,VGA,DisplayPort" and which interface is optimal for connecting a monitor.

Previously, to connect a monitor to a computer, only an analog interface was used VGA. Modern devices have connectors "HDMI,DVI,VGA,DisplayPort". Let's see what advantages and disadvantages each of the interfaces has.

With the development of new technologies for flat-panel monitors, the connector capabilities have become insufficient VGA. To achieve the highest image quality, it is necessary to use a digital standard such as DVI. Home entertainment device manufacturers have created a standard HDMI, which became the digital successor to the analog Scan connector. Somewhat later, VESA (Video Electronics Standards Association) developed DisplayPort.

Main interfaces for connecting monitors.

■ VGA. The first connection standard, still in use today, was developed in 1987 by the then leading computer manufacturer IBM for its PS/2 series PCs. VGA is an abbreviation for Video Graphics Array (an array of pixels), at one time this was the name of the video card in PS/2 computers, the resolution of which was 640x480 pixels (the combination “VGA resolution” often found in technical literature means exactly this value).

An analog data transmission system with increasing resolution only worsens the picture quality. Therefore, in modern computers the digital interface is the standard.

. ■ DVI. This abbreviation is oz-naHaeTDigital Visual Interface - digital video interface. It transmits the video signal in digital format while maintaining high image quality.

DVI is backwards compatible: Almost all computers have a DVI-I connector, which is capable of transmitting both digital video data and a VGA signal.

Inexpensive video cards are equipped with a DVI output in the Single Link modification (single-channel solution). The maximum resolution in this case is 1920x 1080 pixels. (Full HD). More expensive video card models have a two-channel DVI (Dual Link) interface. They can be connected to monitors with a resolution of up to 2560x1600 pix.

The DVI connector is large enough that Apple has developed a Mini DVI interface for its laptops. Using the adapter, you can connect devices with Mini DVI to monitors equipped with a DVI connector.

connection interfaces

■ HDMI. The abbreviation HDMI stands for High Definition Multimedia Interface, that is, a high-definition multimedia interface. In modern home entertainment devices such as flat-screen TVs and Blu-ray players, HDMI is the standard connection interface.

As with DVI, the signal is transmitted in a digital format, which means the original quality is preserved. Together with HDMI, HDCP (High Bandwidth Digital Content Protection) protection technology was developed, which prevents the creation of exact copies, for example, of video materials.

The first devices with HDMI support appeared at the end of 2003. Since then, the standard has been modified several times, in particular, support for new audio and video formats has been added (see table above).

For miniature models of equipment there is a Mini HDMI interface; An appropriate HDMI/Mini HMDI cable is included with many devices.

■ DisplayPort(DP). A new type of digital interface for connecting video cards with display devices is intended to replace DVI. The current version of the standard 1.2 allows you to connect multiple monitors when they are daisy-chained into one chain. However, currently there are not many devices with a DP port. Being a direct competitor to HDMI, this interface has a significant advantage from the point of view of manufacturers: it does not require licensing fees. While for each device with HDMI you have to pay four American cents. If the connector on a computer or laptop is marked “DP++”, this indicates that the adapter can be used to connect monitors with DVI and HDMI interfaces.

To ensure that there is enough space on the back of modern video cards for connectors for other purposes, a smaller version of the DP interface was developed. For example, Radeon HD6800 series video cards contain up to six Mini DP ports.

HDMI,DVI,VGA,DisplayPort

Which of these standards will be most widely adopted? HDMI has a very high chance of success, since most devices have this interface. However, there is a new trump card in the deck of Asian manufacturers: according to official data, the Digital Interactive Interface for Video and Audio (DiiVA) provides a throughput of 13.5 Gbps (DP: 21.6; HDMI: 10.21. In addition, as the companies promise, the maximum cable length between devices, such as a Blu-ray player and a TV, will be up to 25 m. There is no information yet on what the DiiVA interface looks like.

Transfer video via USB

Two years ago it became possible to connect monitors via USB using DisplayLink adapters. However, due to the low (480 Mbps) bandwidth, the USB 2.0 connection is not suitable for video transmission. Another thing is the latest version of the USB standard (3.0), providing data transfer speeds of up to 5 Gbit/s.
An adapter from DisplayLink allows you to connect monitors directly to a computer's USB port.

How to connect a computer and a monitor with different interfaces.

Thanks to adapters, there are many connection options (see table below).

Common adapters, such as DVI-I/VGA, are quite reasonably priced. So-called converters that convert the digital DisplayPort output signal into an analog VGA signal are much more expensive.

However, for example, when connecting a TV with an HDMI interface to the DVI connector, there is almost always no sound.

Is it possible to combine devices with different HDMI versions?

With this combination, only the functions of the earlier version of the corresponding interface will be available. For example, if a video card with HDMI 1.2 is connected to a 3D TV that supports HDMI 1.4, then 3D games will only be displayed in 2D format.
Advice. Installing a new driver allows you to add support for HDMI 1.4 in some video cards based on NVIDIA chips, for example GeForce GTX 460.
Which connectors provide the best picture quality?

Testing has shown that the analog VGA interface provides the worst image quality, especially when transmitting signals with a resolution of more than 1024x768 pix. Even 17-inch monitors support this resolution today. Owners of monitors with a larger diagonal and a resolution of 1920x1080 pixel are strongly recommended to use DVI, HDMI or DP.

How to connect a monitor to a laptop?

Most laptops are equipped with connectors for connecting external monitors. First, connect the monitor to the laptop. After that, using the buttons Ш and KPI, you can switch between the following modes.

■ Using an external monitor as the main one. The laptop display turns off and the image is displayed only on the connected external monitor. The best option for movie buffs and gamers.

Clone mode. External monitor and laptop display show the same image

■ Practical for presentations and seminars.

■ Multi-screen mode. Allows you to increase the size of your Windows desktop by using multiple monitors. It is very convenient, for example, when typing text in Word, to have email messages in front of your eyes.

Will it be possible to connect the TV to the computer?

Modern computers and laptops do not have analog video interfaces such as S-Video or a composite connector. Therefore, you definitely won’t be able to connect an old CRT TV. However, the vast majority of flat-panel models are equipped with DVI or HDMI interfaces, which means connecting them to a computer is not difficult.

Netbooks, as a rule, only have a VGA output, and only those TVs that have a VGA input can be connected to them.

Is it possible to connect a monitor via USB

For traditional monitors this is only possible with the optional DisplayLink adapter. However, there are also models on sale that connect directly to a computer’s USB port - for example, Samsung SyncMaster 940 UX.

What is the maximum monitor cable length?

Cable capabilities depend on the connection type. When using DVI, the connection length can reach 10 m, but in the case of HDMI and VGA it should not exceed 5 m. To achieve maximum transmission speed.

What should you pay attention to when purchasing a video cable?

To prevent nearby electronic devices from affecting the quality of the transmitted signal, purchase only well-shielded cables. When using a low-quality cable, other devices may cause interference and in some cases even reduce the data transfer rate. As a result, the screen will display a choppy image or an aliasing effect will appear. Gold-plated contacts prevent corrosion of the plugs due to high air humidity. In addition, the gold-plated contacts used in modern cables reduce the resistance between the connector and the plug, which improves transmission quality. But as you can see from practice: you can forget about all this, gold-plated contacts and other nonsense, with cheap cables made in China, namely, they are supplied complete with monitors and video cards. And they cope with their responsibilities very well.

For reference: once somewhere they gathered music lovers to test cables. There were both gold-plated and platinum contacts, from $1000 per cord and much more. Well, the ratings were given for sound quality. To determine the winner, the competition was held naturally in the dark, the manufacturer was not visible. Well, one of the organizers came up with the idea of ​​sending a signal through an ordinary iron crowbar (which is used to hammer the ground). And what do YOU ​​think, he took one of the prizes.

And music lovers spent a long time explaining what crystal clear sound comes through this cool cable. So turn on your head, otherwise I saw the guys have a cable DVI at a price higher than the video card and monitor combined.

Today you can display a video image on a monitor or TV in different ways - there are more and more options for connection ports every year, and it’s not surprising to get confused in the number and difference of interfaces.

Let's look at the most popular formats and determine cases when one or another video port standard is best suited.

VGA

The oldest standard for pairing a PC and a monitor, which still exists today. Developed back in 1987 by IBM, the component video interface uses an analog signal to transmit color information. Unlike more modern standards, VGA does not allow sound transmission - only pictures.

The VGA connector is usually blue with two screws on the sides. It has a 15-pin connector and initially could only work at a resolution of 640 by 480 pixels, using a palette of 16 colors. The standard later evolved into the so-called Super VGA, supporting higher screen extensions and up to 16 million colors. And since the improved standard continued to use the old port and did not change in appearance, it is simply called VGA in the old fashioned way.

This format is most often used on older hardware, but many computers still have this port. What is called - just in case.

DVI

More than ten years after the release of the VGA standard, the DVI format, a digital video interface, saw the light of day. Released in 1999, the interface was capable of transmitting video without compression in one of three modes: DVI-I (Integrated) - a combined digital and analogue transmission format, DVI-D (Digital) - supporting only a digital signal, DVI-A (Analog ) – support only analog signal.

DVI-I and DVI-D ports can be used in single or dual mode. In the second case, the bandwidth is doubled, which allows you to obtain a high-definition screen resolution - up to 2048 by 1536 pixels. However, for this you need to have an appropriate video card. The ports themselves differ in the number of contacts - so the Single link mode uses four twisted pairs of wires (maximum resolution 1920 by 1200 pixels at 60 Hz), and the Dual link mode, a corresponding larger number of contacts and wires (resolution up to 2560 by 1600 at 60 Hz).

It is important to remember that the analog version of DVI-A does not support DVI-D monitors, and a video card with DVI-I can be connected to a DVI-D monitor using a cable with two DVI-D-male connectors. By analogy with VGA, this standard also transmits only video images to the screen without sound. However, since 2008, video card manufacturers have made audio transmission possible - for this you need to use a DVI-D - HDMI cable.

You can also find on the market the mini-DVI format, invented by Apple, which is inclined to make everything smaller. However, the mini-standard only works in single mode, which means it does not support resolutions higher than 1920 by 1200 pixels.

HDMI

High Definition Multimedia Interface or high-definition multimedia interface allows you to transmit digital video and audio signals, and even with the possibility of copy protection. HDMI is smaller in size than its predecessors, operates at a higher speed, and most importantly, transmits sound, which made it possible to retire the previous SCART and RCA (“tulips”) standards for connecting video devices to TVs.

The HDMI 1.0 specification appeared at the end of 2002 and had a maximum bandwidth of 4.9 Gb/s, support for 8-channel audio and video up to 165 MPix/sec (that is, FullHD at 60 Hz). Since then, the standard has been constantly evolving, and in 2013 the HDMI 2.0 specification was released with a bandwidth of up to 18 Gbps, support for 4K resolution (3840 by 2160 pixels at 60 Hz) and 32-channel audio.

Today, the HDMI standard is used not only by computers, but also by digital TVs, DVD and Blu-ray players, game consoles and many other devices. If desired, you can use adapters from HDMI to DVI and vice versa.

The number of pins on HDMI ports starts from 19, and the connectors themselves are available in several form factors, the most common of which are HDMI (Type-A), mini-HDMI (Type-C), micro-HDMI (Type D). In addition, there are HDMI ports for signal reception (HDMI-In) and transmission (HDMI-Out). Outwardly, they are practically indistinguishable, but if, say, your monoblock has both ports, then when you try to display a picture on a second monitor, you can only use one of them, namely the HDMI-Out one.

DisplayPort

In 2006, another video standard for digital monitors was adopted. DisplayPort, like HDMI, transmits not only video, but also audio, and is used to connect a computer with a display or home theater. DisplayPort has a higher data transfer rate, support for resolutions up to 8K (7680 by 4320 pixels at 60 Hz) in version 1.4, released in March 2016, and the image through the port can be displayed on multiple monitors (from two to four, depending from permission).

DisplayPort was specifically designed to output images from computers to monitors, while HDMI was more intended for connecting various devices to a TV. However, these ports can be used together using a Dual-Mode DisplayPort adapter.

There are also variations of Mini DisplayPort, used primarily in laptops. In particular, the smaller format is loved by Apple.

Thunderbolt

Finally, a standard from Intel (in collaboration with Apple) for connecting peripheral devices to a computer. It was Apple that was the first to release a device with this interface in 2011 - the MacBook Pro laptop.

The maximum data transfer speed is 20 Gbit/s when using optical fiber for version 2, while the 3rd version of the interface is capable of operating at speeds up to 40 Gbit/s. Thunderbolt combines not only the DisplayPort interface, but also PCI-Express, which means you can connect almost anything to it. In particular, up to six devices can be connected to one port, which reduces the need to have a huge number of different ports on a device.

The Thunderbolt connector itself is smaller than the mini-DisplayPort, and its third version is a port compatible with USB 3.1, that is, it is made with a USB Type-C connector.

Universal USB

If you are suddenly worried that you will soon have to update all your home appliances due to changing standards, then do not rush. Manufacturers are striving to simplify the story with numerous interfaces and provide support for older devices through adapters. In particular, for HDMI devices you will only need to use an appropriate adapter in order to be able to connect to a modern USB Type-C port.

By analogy with the fact that previously each mobile phone manufacturer had its own charging connector, and now most use a micro-USB port, the video standard is also striving for unification. And the unifying form factor should be the latest generation USB port, through which both monitors and regular headphones and headsets will be connected.

To visualize information processed by a computer, you definitely need a screen. On the technical side, connecting the monitor to the system unit is ensured using a cable. Cable connectors can be of four types: HDMI, DisplayPort, DVI or VGA. Each of them has both its advantages and disadvantages. So what's the best way to connect a monitor? DVI or HDMI or VGA - which option is preferable?

High-Definition Multimedia Interface

Even connecting a screen to a computer has its own standards. So, DVI or HDMI - which is better for a monitor? The choice definitely falls on the last connector. This undeniable leadership is due to the fact that many modern development companies use it by default.

HDMI is the most popular type of interface at the moment. It is used to connect most monitors and TVs. But the use of HDMI is not limited to only these devices. It allows you to connect laptops, tablets, smartphones, game consoles, and multimedia players. HDMI is already a standard for connecting equipment to output images of particularly high quality.

Advantages of HDMI over other connection types

In order to decide whether DVI or HDMI is better for a monitor, you need to remember the advantages of each connection type. The advantages of the second are:

  1. Simplicity. The image is transmitted through one cable, which is very convenient because it avoids the accumulation of a large number of different wires. Thanks to this type of interface, the entire entertainment multimedia system can be converted into digital form quickly and easily. HDMI, due to its wide format, allows you to connect many devices (for example, for a home theater) using the same one cable.
  2. Compatibility. Each new version is perfectly supported and interchangeable with previous ones.
  3. Efficiency. connection (10.2 Gbps) provides transmission of video fragments with a resolution of 1080. Thus, using HDMI, you can watch films of truly high quality. For gamers, this point is important because, thanks to high resolution, gaming speed increases.

HDMI intelligence and innovation

HDMI is a completely digital format that requires no image conversion or compression. In addition, in the future, the developers plan to improve this technology: firstly, they are working on higher resolutions and increased frequencies, and secondly, another know-how is the technology of an expanded color palette, which will include up to a trillion colors, but for now At the moment it is at the development stage. The latter will allow you to get a more realistic and high-quality picture.

Manufacturers and developers of this type of connector are as consumer-oriented as possible, so a two-way connection ensures full interaction of devices with each other. This interface allows you to automatically determine the capabilities of each type of equipment in order to adjust the necessary options. HDMI has learned to control the resolution and aspect ratio of the image. The company's latest development is Consumer Electronics Control - technology that allows you to control playback, recording and even launch a series of commands with one button.

DisplayPort

If you are deciding how best to connect a monitor - DVI or HDMI or DisplayPort - you need to know that the latter option is definitely not suitable for HD lovers. This interface was developed by specialists from VESA, a fairly reputable company in its field. But despite this, many users consider the connector to be the most suitable for connecting the screen and the power supply.

However, programmers and designers, thinking about how best to connect a monitor (DVI or HDMI or D-Sub DisplayPort), will probably give preference to the latter. And all because the main feature of this type of connection is the ability to work simultaneously with several monitors.

Another advantage of the interface is the absence of licensing fees. Another feature of the DisplayPort connector is that each color is transmitted on its own personal channel. Unlike HDMI, it has a locking mechanism and is free of screw fastenings, which maintains reliable operation. DisplayPort, in addition, has quite small dimensions.

Summarizing the above, we can say that the main purpose of this type of connection is to provide communication between the monitor and the computer. This is not the best option for TVs.

Digital Visual Interface

In the nineties, DVI had the status of a standard interface for connecting monitors, but soon lost relevance due to the advent of HDMI. But still, what is the best way to connect a monitor? DVI or HDMI - which option is better? DVI can be used where 4K resolution is not required. This interface supports several modes:

  • digital only (the difference between the digital format is that it does not transmit an audio signal, suitable for computers that do not have speakers);
  • analog only;
  • digital and analog.

Video Graphics Array

In order to fully discuss (DVI or HDMI) which is better for a monitor, it is necessary to remember the long-forgotten VGA. It was once widely used in electronics, but has now become almost extinct. Several years ago, leading IT companies finally abandoned this interface, arguing that they were planning a transition to new high speeds.

But VGA is still found in old computers and projectors. And if it is convenient to use, then why should it be abandoned? After all, he served some faithfully for more than a decade.

Summarizing

How to decide on the choice - DisplayPort, VGA, DVI or HDMI? What is better for a monitor? First of all, you need to indicate the purpose of the interface for each specific connection. The best option would, of course, be HDMI, which is universal. This connection is suitable for both TV and computer.

If multifunctionality is not a priority, then DisplayPort is a good choice for a PC. The connector is now supported and used by many manufacturers. VGA and DVI, as outdated but proven versions, will also find their, although not widespread, distribution. And yet, the most technologically advanced, innovative and promising solutions will be DisplayPort and HDMI.
