Hdmi or vga which is better for the monitor. Comparison of VGA and HDMI connections

Today, the most popular option for connecting a media player to a TV is the HDMI interface, while a DVI interface is most often used for computer monitors. Today we will find out what is the difference between these two technologies or which one is better.

I'll start with a brief description of the technologies:

High Definition Multimedia Interface (HDMI) is a high-definition multimedia interface that allows the transmission of high-definition digital video data and multi-channel copy-protected digital audio signals.

Digital Visual Interface, DVI ("digital video interface") is a standard for an interface and corresponding connector designed to transfer video to digital display devices such as LCD monitors, televisions and projectors. Developed by the consortium Digital Display Working Group.

Similarities and differences between DVI and HDMI

First of all, the difference in size is striking - DVI is much larger, has more outputs, and there are special mechanisms along the edges that allow you to fix the plug. HDMI looks simpler, in some ways even prettier, and differs in small dimensions.

HDMI has the ability to transmit 8-channel audio, while DVI does not have it by default. Of course, there is a DVI interface that supports sound, but there is no sense in it as such, since this interface is most often used for computer monitors, and the latter, as we know, have built-in speakers in exceptional cases - there are very few such models on the market.

DVI has the ability to transmit both analog and digital signals.

Both interfaces use TMDS technology. This means that between them you can use a connection using the most common adapter.

In HDMI version 1.4 and higher, the ability to create a Fast Ethernet connection (100 Mbps) is implemented.

HDMI contains only one digital channel by default (except for the unpopular versions that support two channels). DVI in the DVI-I Dual Link version simultaneously supports one analog and two digital data transmission channels.

HDMI is endowed with so-called HDCP (High-bandwidth Digital Content Protection), “high-bandwidth digital content protection”, which is a media content protection technology designed to prevent illegal copying of high-quality video signals. It is also present in DVI, but not in all versions.

When it comes to image quality, you won't see any difference between technologies.

Outcome

It is necessary to summarize. I want to say that HDMI and DVI are two technologies that cannot be called competitors. Rather, they complement each other and target different market segments. If HDMI is most often used on household appliances, including televisions, then DVI is used on computers. Therefore, it is definitely impossible to say which is better and which is worse.

Disadvantages of the image when using analog connection technologies are clearly visible on a digital TV. Graphics devices create a digital useful signal that is subsequently recoded to analog. And again in numbers. As a result, the user sees a slight double vision of the picture, "phantom" copies of graphic objects, buttons, screen text. This is especially noticeable if you compare a CRT monitor with an LCD on an analog connection. Better monitor - worse picture.

There is no other way to get rid of interference than to use the connection of devices using the dvi port or the hdmi connector, which the first generations did not have. There was only an analog VGA connection, which has no protection against electrical noise. It would seem, what does the TV have to do with it. This problem only affects PCs - but no, it's not that simple. Connection using either the hdmi connector or the dvi port - any modern TV is familiar with this today, since both ports are present on the side or rear panel. But which connection is better?

Why two, where is one?

So the analog signal is not. The user sees a picture without interference only if a special cable is used between the devices through such a communication device as the hdmi connector. Or is the dvi connection better? What is better for digital image and sound transmission? The user sees two digital connectors for a digital cable. What is their difference? Moreover, connection using an hdmi cable through the dvi port and vice versa is possible using adapters. True, it is better to use similar connectors, since one sometimes does not see the other. And yet both connectors use the same signal transmission technology - so why do you need this choice? Their comparative characteristics will help to answer the question of what is better to choose.

The transmission of information through each cable from a digital device to a TV is carried out using TMDS technology. That is, where to connect the player - there is no difference.
Both connectors are connected by one cord, for which special adapters have been created.
The main difference between hdmi is the ability to transmit an audio signal to the TV. There are dvi cord models that also allow not only seeing, but these are already exceptions to the rule. The advantage of the latter is not the transmission of sound, but the ability to connect and play a device using an analog signal on the TV.
The hdmi interface is usually single-channel, but the cable is equipped with a 100Mbps Ethernet channel. In dvi, as a rule, several data transmission channels are implemented, including analog. Whether it is needed or not is another question.
The signal strength, noise immunity and material of manufacture are excellent for both cables.

In fact, the assertion that you need exactly "this" cord to tune your TV to receive a digital signal can be challenged. The playback quality directly depends on what kind of device the user decided to connect. What he sees on the screen is not affected by the connecting cable, but by the quality of the incoming signal.

Competitors or partners

So, it is clear that the dvi interface and the hdmi interface are not competitors at all. The first cable is designed for connection to monitors, professional equipment - an Ethernet channel for a monitor that can only help to see is useless. Sound transmission is impossible without speakers - but they are always on the TV. The development of dvi technology was carried out for the connection of computer technology or professional equipment that only sees. In everyday life, it is more convenient to use the hdmi interface to connect the TV to digital picture and sound sources.

Problems and solutions

What cannot be avoided in life is breakdowns. But a breakdown that interferes with connecting a digital connection rarely requires buying a new TV. If hdmi does not work for you, check the connection socket, maybe there is simply no contact. Mounting systems in TVs suffer from insufficient mechanical rigidity and an externally strong connection sometimes needs to be reconnected. There is no contact - automatically there is no signal flow to the processing systems, there is no image and sound. A TV with such a defect, constantly, sometimes sees or does not see the connected device. If there are several hdmi connectors in the TV, try connecting the connecting cable to the next port - sometimes the rigidity of the socket is lost, the cord falls out a little. You can also act in the absence of sound.

Device conflict can be a problem

Sometimes a solution such as finding a clear sequence of switching on of video and audio source devices helps to get rid of the problem. For example, you managed to connect a Blu-Ray player, a music center, turn on the TV, but there is no information. We change the order - we get sound playback, picture and viewing pleasure.

This advice is relevant if the TV has three or more digital signal sources. In addition, since the problem may not lie in the TV, but in one of the satellite devices. This is quite possible. Devices may conflict with each other or due to the breakdown of one of them. Connecting with a "cause" is often a source of problems, which is not immediately noticeable.

It happens that users, having decided which hdmi cable to choose, subsequently connect it to the device via the dvi output. And then they complain about the lack of sound, forgetting that the device does not see it. The settings for additional functions in a modern TV of the latest generations are more complicated than in previous ones. It is better to consult in advance about the functions implemented in the TV, to clarify what kind of cable is needed to connect this or that device.

Connecting the monitor to other devices is carried out using various interfaces, which are currently abundant. Depending on the technological solution, there are two types of connection options - analog and digital. The latter are represented by two main interfaces - DVI D or HDMI. What is better and what, in fact, is the difference between these technologies? Which connector should you choose? Further, it will be considered in more detail, the better HDMI than DVI.

Requirements of modern technology

To determine which connector is better - DVI or HDMI, it is worth figuring out why it is necessary to consider only these two connectors, because there are other interfaces, for example, DisplayPort or VGA. Firstly, DisplayPort is used primarily to connect a monitor to a computer, providing a connection between multiple screens, but such an interface is definitely not suitable for HD. VGA is now considered an outdated solution; many leading companies have refused to use it in their technology. By the way, it was thanks to VGA that

But analog broadcasting is also receding into the background today as it clearly shows most of the imperfections in the image. The device first converts to analog, and then vice versa. Excessive image transformations lead to the appearance of interference on the screen - doubles, copies of objects, buttons or text become a frequent problem. These shortcomings are especially noticeable on the first modern liquid crystal monitors, which only supported VGA connection.

As for the connectors, most manufacturers now place ports for both digital cables on the rear panels of the equipment. But, as a rule, this only complicates the task when you need to decide which cable is better - HDMI or DVI.

Common features of interfaces

Both HDMI and DVI transmit video using the same technology called TMDS. The necessary information in this case is encoded in such a way as to obtain the most harmonious bit sequence. Thanks to the latter, a high frequency level is achieved and, as a result, a better image.

In addition, only one cable is used for both one and the other port (despite the fact that HDMI is a single-link, but DVI is a multi-link solution, which will be discussed below). This is possible thanks to the use of special adapters.

Distinctive features

Many personal computer users opt for Why is this so - the better HDMI? What DVI cannot boast of? There are two main differences:

HDMI cable can carry not only video but also audio signal. This provides high quality not only sound, but also pictures. Most DVI models do not have this function, although, of course, there are exceptions to the rule.
is a single-channel cable, but the data transfer rate reaches one hundred megabits per second. But the products of the competing company are distinguished by several channels, one of which transmits an analog signal. For devices operating on such a signal, a DVI cable is a godsend. Thus, the company keeps pace with the times, but also does not ignore the needs of the owners of equipment that cannot boast of an innovative "filling".

To decide what is better HDMI than DVI, you need to understand that the image quality is more dependent on the device that needs to be connected. The picture that appears on the screen is affected by the signal level. But the stability and quality of image transmission is already provided by the cable.

But you should not try to connect one cord to the place of another, for this there are special adapters. Otherwise, you can simply lose the soundtrack. Although both interfaces work using the same technology, the differences make themselves felt.

High-Definition Multimedia Interface

What is better than HDMI than DVI is that it is the High-Definition Multimedia Interface that is used by many companies that produce equipment. It is such a widespread interface that with the help of hdmi you can connect not only TVs and monitors to computers, but also laptops, tablets and smartphones, game consoles and players.

A cable consisting of only one channel is still wide-format, making it possible to form a whole system from various multimedia devices. The latter is especially necessary in some cases.

The new versions of the cable have excellent compatibility and easily replace previous models. HDMI has good bandwidth, which is important for gamers or just those users who like high speeds and enhanced audio. At the same time, HDMI is completely innovative, it only supports digital format. That is, any old models of equipment cannot be connected with it.

Digital Visual Interface

The DVI interface has three flavors that support various modes - digital, analog, and analog-to-digital. A picture with a high expansion, this cable can transmit at a distance of no more than five meters. Signal transmission can be carried out in two modes. The first is single link, the second is dual link. The latter ensures operation at high frequencies. So, if the picture is of poor quality when using single mode, it is dual link that will correct the situation.

Competitive advantage

HDMI is the smarter interface anyway. Developers follow trends and keep pace with the times. Most models of modern technology at the moment and in the near future will definitely use this type of cable.

HDMI or DVI for PC, which is the best choice? In this case, you can use either one or the other interface. The final choice depends on the destination. If high-quality sound is important, then it is better to use the first connector, if this is not necessary, DVI is also suitable for the connection. This type of interface is especially good because, although its developers are developing technologies, they also do not forget about those who use old devices. After all, quite a few users still have computers and televisions that are no longer “in trend”. In this case, it is better to opt for DVI.

Computers and laptops have been equipped with not one, but two or three types of connectors at the same time for 10 years. The ports differ in both size and appearance. What type of monitor connection do I prefer? The article also discusses the practical usefulness of simultaneously connecting two or even three monitors.

Common but old types of connectors

VGA (Video Graphics Array): a legacy classic

The blue trapezoidal interface dominated the computing field for 25-30 years. It handled older CRT displays superbly due to its analog nature. But flat LCD screens appeared - digital devices, then resolutions began to increase and the good old VGA began to lose ground.

Today, it is less and less embedded in video cards, but still many devices (household players, projectors, TVs) are equipped with support for the hopelessly outdated VGA. Probably, for a few more years the "old man" will remain not very desirable, but a ubiquitous de facto standard - if there are doubts about which cable can be used to connect a monitor in a neighboring office, then take VGA.

DVI-I (Digital Visual Interface): Another long-lived video interface

Actually there are several of them: DVI-A, -D and -I, plus their varieties. But when it comes to the most common DVI-I standard, it means analog-to-digital DVI-I Dual Channel - this specification is built into most PCs.

At one time, DVI came to replace VGA, which was rapidly becoming obsolete in the mid-2000s. The ability to transmit both analog and digital signals, support for large (in that era) resolutions and high frequencies, the absence of inexpensive competitors: DVI regularly serves as a standard today. But it is unlikely that his active "life" will last more than another 3-4 years.

Resolutions higher than the minimum comfortable FullHD for today are increasingly found even in inexpensive computer systems. With the growth of megapixels, the once serious capabilities of DVI come to an end. Without going into technical details, we note that the peak capabilities of DVI will not allow displaying an image with a resolution above 2560 x 1600 with an acceptable frequency (above 60 Hz).

Modern video interfaces

HDMI (High Definition Multimedia Interface) - the king of multimedia

Once absurd for the Russian ear, the abbreviation "hi-di-um-ay" is increasingly entering our lives. Why has HDMI become so popular? It's simple:

arbitrarily long wires (okay, to be honest - up to 25-30 meters);
sound transmission (even multichannel!) along with video - goodbye, the need to buy separate speakers for TV;
the most convenient small connectors;
support is everywhere - players, "zomboys", projectors, video recorders, game consoles - it's hard to immediately recall equipment where there would be no HDMI connector;
ultra-high resolutions;
3D picture. And yes, it is possible together with ultra-high resolutions (HDMI 4b and 2.0 versions).

The prospects for HDMI are very bright - development continues, in 2013 the specifications of version 2.0 were adopted: this standard is compatible with old wires-connectors, but supports more and more impressive resolutions and other "tasty" features.

DisplayPort (DP): a connector that is just becoming ubiquitous

And DisplayPort is amazingly beautiful in appearance ...

For many years computers were rarely equipped with this direct competitor to HDMI. And - despite the fact that DisplayPort was good for everyone: and support for very high resolutions along with a stereo signal; and audio transmission; and impressive wire length. It is even more profitable for manufacturers than licensed HDMI: there is no need to pay the developers of the standard the 15-25 cents that are due to HDMI owners.

The DP connector was simply out of luck in its early years. However, computers are increasingly equipped with a pair of Display Port of the modern standard version 1.4. And on its basis another popular standard with great prospects was "born": the "younger brother" of the Display-port ...

Mini DP (Mini DisplayPort)

Along with HDMI and the outdated VGA, the Mini DisplayPort connector is built into almost every computer and laptop. On his side are all the advantages of the "big brother", plus the miniature size - an ideal solution for ever thinning laptops, ultrabooks, and even smartphones with tablets.

Audio signal transmission so as not to buy separate speakers for the monitor? Please - how many channels are you? Stereoscopy even in 4K? Yes, let the interface have to flex all its electronic muscles. Compatibility? There are a wide variety of adapters on the market, almost for any other connector. Future? The Mini DP standard is alive and well.

Thunderbolt: Exotic Monitor Connectivity Options

There are some. For a year now, Apple has worked with Intel developers to promote the fast, versatile, but insanely expensive Thunderbolt interface.

Why do monitors also need Thunderbolt? The question remains for a year without an intelligible answer.

In practice, monitors with its support are not so common, and there are big doubts about the justification of Thunderbolt for video signal transmission. Is that the fashion for everything "apple" ...

Unfortunately, beyond the scope of the article, there is an interesting opportunity to connect screens to a computer (and even supply power to them!) Using the USB 3.0 interface (or, even more interesting, 3.1). There are many prospects for this technology, and there are also advantages. However, this is a topic for a separate review - and for the near future!

How do I connect a new monitor to an old computer?

An "old computer" usually refers to a PC with only one port - VGA or DVI. If a new monitor (or TV) categorically does not want to be friends with such a port, then you should purchase a relatively inexpensive adapter - from VGA to HDMI, from Mini DP to DVI, etc. - there are many options.

When using adapters, some inconveniences are possible (for example, there is no way to transmit sound or images with a particularly high resolution via VGA), but such a scheme will work properly and reliably.

Video signal without wires (WiDi)!

There are also such interfaces, even several. Intel Wireless Display (aka WiDi, or "wi-dai", no matter how strange it may sound to a Russian-speaking reader): an adapter priced at about $ 30 plugs into a USB port on a TV or monitor (if the technology is supported by the manufacturer).

The signal is sent via Wi-Fi, on the screen - the video image. But this is only in theory, but in practice, significant obstacles are the distance and the presence of walls between the receiver and the transmitter. The technology is interesting, it also has prospects - but so far nothing more.

Another wireless video interface is Apple's AirPlay. The essence and practical application is the same as that of Intel's WiDI. Expensive, not too reliable, far from practical.

The solution is more interesting, but so far not widely used - Wireless Home Digital Interface (WHDi). It's not exactly Wi-Fi, although it's a very similar wireless technology. Key feature - proprietary protection against interference, delays and distortion.

Connecting multiple monitors at the same time

Even a novice user can cope with the task of attaching a main or additional screen: the monitor is connected to a PC or laptop no more difficult than a USB flash drive. It is possible to connect a monitor to a computer only in the correct way: the connector simply will not fit into a connector that is not intended for it.

An excellent feature of modern video cards and operating systems is the ability to connect multiple monitors at once to one signal source (PC, laptop). The practical benefits are enormous, moreover, in two different versions.

1. Image clone mode

The main computer screen is working normally. But at the same time, the image is completely duplicated on a large-scale TV and / or projector. All you need to do is connect the video cable to both the large screen and the projector. Sound is transmitted along with the image if you use modern connectors (HDMI, Mini DP).

2. Multi-screen mode

The resolution of monitors is constantly growing - but there are always tasks for which I would like to have a wider screen. Calculations in a large Excel spreadsheet, or work with a couple of browsers at once; design tasks and video editing. Even typing is more convenient when there is also an additional display next to the main one. "Gap" - the frames of the screens in practice interfere no more than the frames of the glasses - after a few minutes you simply do not notice them. Gamers also like to use several monitors at once - immersion in the gameplay with this scheme captures much more. By the way, some AMD video cards support up to 6 monitors simultaneously (Eyefinity technology made a lot of noise in the IT community 5 years ago).

Picture: This is how you can call up the connection settings of the second or third monitor: Click on "Graphics Settings" from Intel or Nvidia.

How to connect 2nd monitor to computer? Insert the cable connector - most likely, the image will instantly be "picked up" by the second screen. If this did not happen, or additional settings / other mode are required - a minute's work in the graphics driver of the video card. To get into this program, just right-click on the icon of the Intel, Nvidia or AMD video driver - depending on which video adapter is installed in the PC, and select the "Settings" item. The video adapter icon is always present in the Control Panel, and in almost all cases - in the Windows tray, near the clock.

To visualize information that is processed by a computer, you definitely need a screen. On the technical side, the monitor is connected to the system unit with a cable. There are four types of cable connectors: HDMI, DisplayPort, DVI, or VGA. Each of them has both advantages and disadvantages. So what's the best way to connect your monitor? DVI or HDMI or VGA - Which is Preferred?

High-Definition Multimedia Interface

Even in connecting a screen to a computer, there are 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 HDMI is not limited to these devices. It provides connection of laptops, tablets, smartphones, game consoles, multimedia players. HDMI is already a standard for connecting equipment for outputting images of especially 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 type of connection. The advantages of the second are:

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, you can easily and quickly digitize your entire entertainment multimedia system. HDMI, due to its widescreen format, allows the connection of many devices (for example, for home theaters) using the same cable.
Compatibility. Each new version is perfectly supported and interchangeable with previous ones.
Efficiency. The bandwidth of the connection (10.2 Gb / s) ensures the transmission of video fragments with a resolution of 1080. Thus, using HDMI, you can watch movies of really high quality. For gamers, this moment is important because, thanks to the high resolution, the gaming speed increases.

HDMI intelligence and innovation

HDMI is an all-digital format that does not require image conversion or compression. In addition, in the future, developers plan to improve this technology: firstly, they are working on higher resolutions and increased frequency, and secondly, another know-how is the technology of an extended color palette, which will include up to a trillion colors, but for now the moment it is under development. The latter will allow you to get a more realistic and high-quality picture.

Manufacturers and developers of this type of connector are focused on the consumer as much as possible, therefore the 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 resolution and aspect ratio. The latest development of the company is Consumer Electronics Control - the technology allows you to control playback, recording and even launching a series of commands with a single button.

DisplayPort

When 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 the VESA company, which is quite authoritative in its field. But despite this, many users find the connector 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 multiple monitors.

Another advantage of the interface is the absence of license fees. Another feature of the DisplayPort connector is that each color is transmitted on its own personal channel. Unlike HDMI, it has a latching mechanism and is free from screw fixings, which maintains reliable operation. DisplayPort is also quite small in size.

Summarizing the above, it can be argued that the main purpose of this type of connection is to provide communication between the monitor and the computer. For TVs, this is not the best option.

Digital Visual Interface

DVI in the nineties had the status of a standard interface for connecting monitors, but soon lost its relevance due to the appearance of HDMI. But still, what is the best way to connect a monitor? DVI vs HDMI - Which Option Is Better? DVI can be used where 4K resolution is not required. This interface supports several modes:

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

Video Graphics Array

In order to fully talk about what (DVI or HDMI) is better for a monitor, you need to remember about the long-forgotten VGA. It was once widely used in electronics, but now it is practically extinct. Several years ago, leading IT companies finally abandoned this interface, arguing that they were planning to move to new high speeds.

But still VGA is still found in old computers, projectors. And if it is convenient to use it, then why should you refuse it? After all, he served some of them faithfully for more than ten years.

Summarizing

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

If versatility doesn't come first, then DisplayPort is a good choice for PCs. The connector is now supported and used by many manufacturers. VGA and DVI, as outdated but tested versions, will also find their, albeit not widespread, but widespread. Yet the most technologically advanced, innovative and forward-looking solutions will be DisplayPort and HDMI.

Comparison of DVI and HDMI

To connect the monitor to a computer, special connectors are used that are soldered into the motherboard or located on the video card, and special cables suitable for these connectors. One of the most popular types of ports today for outputting digital information to a computer monitor is DVI. But it is losing ground to HDMI, which is the most popular solution today.

general information

DVI connectors are beginning to become outdated, so if you decide to build a computer from scratch, it is better to find a motherboard and video board that have more modern connectors for outputting digital information. Owners of old monitors or those who do not want to spend money, it is better to choose models with DVI or where it is present. Since HDMI is the most common port, it is advisable to choose video cards and motherboards where it is available.

HDIMI connector types

The HDMI design has 19 pins, the number of which does not change depending on the type of connector. The quality of work can change from it, but the types of the interface themselves differ only in size and technique in which they are used. Here are the characteristics of all available types:

Types of connectors for DVI

For DVI, the number of pins depends on the type of connector and varies from 17 to 29 pins; the quality of the output signal is also very different depending on the types. Currently the following types of DVI connectors are used:

HDMI also has several types of connectors, which are classified by size and transmission quality, but they all work only with LCDs and are capable of providing higher signal and image quality than their DVI counterparts. Working only with digital monitors can be considered both a plus and a minus. For example, for owners of outdated monitors, this will be a disadvantage.

Distinctive features

Despite the fact that both cables use the same technology, they have noticeable differences between them:

See also: Which is better than DisplayPort or HDMI

There are also major differences in cable performance. HDMI has several types of them, each of which is made of a certain material and is capable of transmitting a signal over long distances (for example, a fiber optic version transmits a signal over more than 100 meters without problems). Consumer-grade copper HDMI cables boast up to 20 meters in length and 60Hz transmission in Ultra HD resolution.

DVI cables are not very diverse. On the shelves, you can find only consumer cables that are made of copper. Their length does not exceed 10 meters, but this length is quite enough for home use. The transmission quality practically does not depend on the cable length (more on the screen resolution and the number of connected monitors). The lowest possible refresh rate for DVI is 22 MHz, which is not enough for comfortable video viewing (not to mention games). The maximum frequency is 165 MHz. For comfortable work, 60 MHz is enough for a person, which this connector provides without problems under normal load.

If you choose between DVI and HDMI, then it is better to stop at the latter, since this standard is more modern and perfectly adapted for new computers and monitors. For those who have old monitors and / or computers, it is advisable to pay attention to DVI. It is best to purchase an option where both of these connectors are mounted. If you need to work with multiple monitors, then better pay attention to DisplayPort.

We are glad that we were able to help you solve the problem.

Monitor connection. DVI vs HDMI - Which is Better for a Monitor?

A screen is needed to visualize information processed on a computer. From a technical point of view, the monitor is connected to the system unit via a cable. There are four types of cable connectors: VGA, DVI, Display Port, and HDMI. Each of these ports has its own disadvantages and advantages. What is the best way to connect a monitor? Which option is preferable to use?

HDMI (High Definition Multimedia Interface)

Their own standards exist even when the screen is connected to a computer. Which is better, HDMI or DVI? It's definitely better to opt for HDMI. The indisputable leadership of this interface is due to the fact that many modern development companies use it by default. HDMI is by far the most popular type of interface. It is used to connect most TVs and monitors. However, HDMI applications are not limited to these devices. Using HDMI, you can connect laptops, tablets, game consoles and multimedia players. HDMI has already become the standard for connecting equipment for displaying images of especially high quality.

HDMI: advantages over other types of connections

To determine what is still better for a monitor - DVI or HDMI, it is necessary to list the advantages of each of the presented connection types. The advantages of HDMI are as follows:

Simplicity: the image is transmitted to the screen via one cable, which is very convenient and avoids the use of a bunch of different wires;

With HDMI, you can easily and quickly digitize your entire entertainment multimedia system;

HDMI connects multiple devices with just one cable;

Compatibility: each new version of the connector is supported and interchangeable with the previous ones;

Efficiency: The bandwidth of the connection is 10.2 Gbps, which allows for the transmission of video clips with a resolution of 1080. This allows you to watch truly high quality movies using HDMI. This moment is especially important for gamers, because thanks to the high resolution, you can increase the gaming speed;

HDMI innovation and intelligence.

HDMI is an all-digital format. It does not require image conversion or compression. It is also worth noting that the developers plan to improve this technology in the future. They are working on higher resolutions and higher frequencies. Another know-how is also the technology of the extended digital palette. It will contain up to a trillion colors. While this technology is still at the development stage. Using an extended palette will allow you to get a better and more realistic picture. Developers and manufacturers of this type of connector are consumer-oriented to the maximum extent. Bidirectional connectivity allows devices to fully interact with each other. This interface makes it possible to automatically determine the capabilities of each type of technology in order to adjust all the necessary options. HDMI allows you to control the resolution and aspect ratio of the image. Also one of the latest developments is the Consumer Electronic Control technology, which allows you to control recording, playback and launching a series of commands with a single button.

If you cannot decide how best to connect a monitor - via HDMI, DVI or Display Port, then it must be borne in mind that the latter option is definitely not suitable for HD quality lovers. This interface was developed by specialists from VESA, which is quite reputable in its field. Despite this, many users find that this connector is perfect for connecting the screen and the power supply. Designers and programmers, thinking about an interface for connecting a monitor, will probably give preference to Display Port. This is due to the fact that the main feature of this type of connection is the ability to work with several monitors at once. Another important advantage of the Display Port interface is the absence of royalties. Another feature of the Display Port connector is that each color is transmitted on its own personal channel. This interface, unlike HDMI, has a latch mechanism. There are no screw mounts on it, which also maintains reliable operation. The Display Port is also small in size. Considering all of the above, we can safely say that the main purpose of the Display Port connection is to provide communication between a computer and a monitor. For connecting TVs, Display Port is not the best option.

DVI (Digital Visual Interface)

The DVI standard in the 90s had the status of an interface for connecting monitors. With the advent of HDMI, it has lost its relevance. But what is the best way to connect a monitor? Is it better to use DVI or HDMI? The DVI interface can be used when 4K resolution is not required. This interface supports several modes of operation: digital only (does not transmit an audio signal, suitable for monitors without speakers), analog only, digital and analog.

VGA (Video Graphics Array)

To fully talk about what is still better for a monitor - DVI or HDMI, you need to remember the long-forgotten VGA interface. It was once widely used in electronics. Today this interface is almost extinct. Several years ago, leading IT companies made a decision to completely abandon this interface. They argued their actions by the fact that they were planning to move to higher speeds. Even today, the VGA connector can still be found on older computers or projectors. Why should you refuse them if they are convenient to use? For some users, the VGA connector has served faithfully for over 10 years.

Conclusion

How do you make the right choice: Display Port, DVI, VGA or HDMI? What is the best way to connect the monitor? First of all, it is necessary to indicate the purpose of the interface for a specific type of connection. HDMI is a universal interface today, so it would be better to use it. This type of connection is suitable for both a computer and a TV. If versatility is not important for the user, then Display Port will be a good choice for connecting a personal computer. Today this connector is supported and used by most computer manufacturers. But VGA and DVI connectors can already be considered obsolete. But despite this, they are still proven connection types and will find their distribution. The most technologically advanced, promising and innovative connectors are still HDMI and Display Port.

WHAT IS BETTER dvi or hdmi

What's best for a computer monitor? Using a DVI cable or HDMI? Unlike disputes between the best OS, the choice here lies on the surface. In fact, this is the same as comparing a wheel and ... a wheel. For it doesn't matter.

Which is better: HDMI or DVI?

Opened Wikipedia? The World Library also answers our question. I will quote it in my own words:

There are only two differences between DVI and HDMI:

1) HDMI is more compact

2) Supports the transmission of multichannel digital audio signals.

In practice, there are slightly more differences.

For example, DVI does not support audio transmission, i.e. you will have to use a separate cable. And hdmi, on the other hand, can play 8-channel audio.

By the way, some pseudo experts argue that it will not be possible to play video of blur quality on DVI. Well, this is a delusion. Refers to Single-link DVI, and this is a little from another opera. Everything will play, don't worry.

As for the image quality, the picture will be o-di-na-ko-howl on both dvi and hdmi

P.S. If anyone swears, claiming the opposite, then the whole point, I'm sure of this, is a faulty cable. If it is damaged somewhere, the picture may become worse.

Lack of compatibility.

adapter

Some devices have only one port.

But it doesn't matter, because in computer stores 100% there is an adapter.

Why is HDMI better than DVI? Similarities and differences

Requirements of modern technology

To determine which connector is better - DVI or HDMI, it is worth figuring out why only these two connectors need to be considered, because there are other interfaces, for example, DisplayPort or VGA. Firstly, DisplayPort is used primarily to connect a monitor to a computer, providing a connection between multiple screens, but such an interface is definitely not suitable for HD. VGA is now considered an outdated solution, many leading companies have refused to use it in their technology. By the way, it was thanks to VGA that the analog signal was transmitted.

But analogue broadcasting today is also receding into the background due to the fact that it clearly shows most of the imperfections of the image. The device first converts a digital signal to analog, and then vice versa. Excessive image transformations lead to the appearance of interference on the screen - doubles, copies of objects, buttons or text become a frequent problem. These shortcomings are especially noticeable on the first modern LCD monitors, which only supported VGA connection.

Common features of interfaces

Distinctive features

Many personal computer users opt for the High-Definition Multimedia Interface. Why is this so - the better HDMI? What does DVI not boast of? There are two main differences:

HDMI cable can carry not only video but also audio signal. This provides high quality not only sound, but also pictures. Most DVI models do not have this function, although, of course, there are exceptions to the rule.
The High-Definition Multimedia Interface is a single-channel cable, but the data transfer rate reaches one hundred megabits per second. But the products of the competing company are distinguished by several channels, one of which transmits an analog signal. For devices operating on such a signal, a DVI cable is a godsend. Thus, the company keeps pace with the times, but does not ignore the needs of the owners of equipment that cannot boast of an innovative "filling".
