Map adapter to DVI VGA monitor. DVI-D adapter on VGA

Each PC user is sooner or later encountered with connecting their laptop or personal computer to the monitor using various cables and connectors. All of them differ among themselves By structure, quality pictures and maximum permissible length cable. In the 90s for connecting CRT monitors 15-pin VGA connector used, which issued good image For that time. Over time, the permission that VGA gives it not enough and a new 17 (17-29) pi came to replace new interface DVI with the ability to display a much greater permit because of its greater throughput.

DVI connector

For the development of Digital Visual Interface (DVI), large companies have combined their efforts. Together, it was decided to convert the signal twice twice. As a result, the developers came to a solution to create a single digital interface, which can output the original image without unnecessary changes and loss of quality.

Basic principle of workthe interface is B. new technology TMDS data coding protocol. The information previously implemented by the protocol is sequentially transmitted to the device.

The interface allows you to achieve the resolution of 1920x1080 at a frequency of 60 Hz. Such parameters allows you to achieve bandwidth 1.65 GB / s and this when using one TMDS connection. If two compounds are used, then speed will increase to 2 GB / s. With such high DVI indicators, the head is superior to their predecessors.

For simple user Explain how good the Digital Visual Interface can only say that this is a digital video interface. It will not be difficult to distinguish it from an analog predecessor - the connectors are always white, which does not make it possible to confuse it with others. The shape and more pins is also the characteristic distinction of the interface.

The interface cable is limited in length, like other connectors, maximum length it It is no more than 10 m, which is 7 meters more than VGA.

Main types and differences

In addition to the characteristic differences from other Digital Visual Interface interfaces, it is also different. The main differences between them are the number of channels and the availability of an analog signal transmission. Consider popular variations in Read more:

You can simply sum up about the difference between the connectors, you can simply - the letter D says about the presence of a digital signal, the letter A is only analog, letter I indicates the presence of both types of signal.

In the case when there is a digital visual interface on the video card, and an adapter is suitable on the monitor only. When acquiring adapters, you need to understand the difference between DVI-I and DVI-D, the first will be able to transfer the signal to VGA. There is an analog channel, but the second does not have an analog communication channel and transfer the image through it through the adapter will not work, for this use special expensive converters.

In addition to the DVI-VGA and VGA-DVI adapters, there are also other DVI-HDMI, HDMI-DVI, DVI-DisplayPort, DisplayPort-DVI, they all transmit digital signal and connection problems should not occur.

Disadvantages of technology

The only significant disadvantage of technology is cable length limit. For example, when using a cable of 15 m long, the maximum resolution that can be achieved is 1280x1024, but if you use only 5 meter cable, the resolution will increase to 1920x1200. If you want to connect the device at a high distance without losing the signal will have to be used additional repeatersthat will strengthen the signal.

VGA connector

In 1987, Canon provided the world a new VGA connector (Video Graphics Array), which was installed on the video card of the same name. The capabilities of the technology was more than enough, because the initial resolution was 640x480. The maximum possible permission without loss of image quality that is capable of issuing Video Graphics Array is 1280x1024. Despite the fact that more efficient interfaces have long appeared that the VGAs from the market displaces, many TVs and video devices are still completed with this connector. The reason for the displacement was the emergence of new monitors that require greater permission.

The connector has a 15-pin spike and marked with blue (with rare exceptions), which makes it easy to distinguish it from DVI (white). Maximum cable long Connection is limited to 3 m.

Due to the development of technology appeared new standard Super Video Graphics Array or SVGA, which uses the same 15 pinov connection as the Video Graphics Array but significantly exceeds it technically. The main difference between SVGA from VGA is number of displayers displayed, they are in new version The interface was 16 million, at 256 colors at the old one.

Main species

VGA connectors have three main varieties of DDC1, DDC2, E-DDC:

DDC1 - Allows the monitor to unilaterally transmit data with information about its characteristics to the computer. After which the video card determines this information on the cable and detects the DDC monitor connected to it
DDC2. - The specification of this species allows you to exchange information in a two-way manner. At first, the monitor transmits its data to the computer, after which the computer adjusts the desired parameters under the connected monitor.
E-DDC. - It is the most effective specification. Information on the data of the connected monitor was stored in the device's memory.

All 15 contacts are located in 3 rows of 5 contacts. The first three contacts They are responsible for the transmission of an analog video signal of three different colors (1,2,3). Each of them has its own earth - 6,7,8, respectively. 13 and 14 contacts are responsible for horizontal and vertical sync. In addition to transmission of the video signal, the interface has a bilateral connection with the monitor.

Interface pinout:

If we are talking about the mini VGA mini clock (reduced analogue with the same parameters), then the pinout will be as follows:

Extension glands

There are situations where the computer and the connected monitor or TV are in different rooms and the cable of non-standard length will be required to connect them. It can be bought in any computer store, but two problems appear:

too high price cable - from $ 20 per 15 meters;
rigidity Standard cable, which becomes a big problem for beautiful and proper laying in the plinth. If, when installing the cable, you need to go through the wall, the factory cable will not clearly help. You will have to drill a hole with a diameter of 40 mm.

In such cases, an ideal solution will be made by an extension. This will come to the aid of the usual twisted pair of 5 or 6 categories.

In the question of the price, it significantly wins the factory extensionist Video Graphics Array, its price is about 15 rubles per meter, and the diameter is only 8 mm.

Using only 8 contacts, twisted pair can easily solder the extension cord, but you can even do it easier to buy an adapter VGA - RJ-45 in the store.

DVI-D - VGA adapter do it yourself

It is impossible to find such an adapter. Wine things are that technologies use different ports and data types. If you carefully look at the DVI-D pinout, it will become noticeable that on it there are no contacts To transfer an analog signal to be required for VGA.

In this case, can help converterDVI-D - VGA, which converts a digital signal outgoing from Digital Visual Interface, in analog. This is the only connection option.

It is worth notingThat if I break 4 "extra contacts" due to which the usual adapter is not inserted into the connector, it will not work anyway, since they are responsible for the transmission of an analog signal.

Maximum cable length

All interfaces have a limit on the maximum permissible length of the cable at which the quality of the signal is not lost. The more the length of the cable, the worse the signal, and, accordingly, the maximum resolution. For each view, the maximum length is different, since the interfaces use various technologies and types of signals.

For DVI - 10, VGA - 3 m, HDMI - 10 m.

Difference DVI and VGA

The main differences of these connectors is maximum resolution and quality pictures. In addition, Digital Visual Interface has from 17 to 29 pins, while VGA has only 15. Another difference is the type of signals with which interfaces work: VGA has an analog, and Digital Visual Interface is digital. It is for this reason that VGA has to be made of conversion twice, which significantly worsens the quality of the resulting image.

What is better than DVI or HDMI

In comparison, these two interfaces can be said about some of their equivalent. The big advantage of HDMI is that with just one cable, both video and audio data can be transmitted, thereby reducing the number of wires that in modern multimedia systems are abuse. Essential difference is maximum resolutionwhich HDMI can at the moment can be 10240 × 5760.

Difference between VGA and HDMI

It is incorrect to compare two of these interfaces because of their difference in the time of creation. HDMI is a fairly new connector that provides the user with an excellent picture and an excellent sound of everything in one cable. Video Graphics Array is now used for the most part in an old technique not compatible with new technologies.

New video cards, such as GTX 1060, 1070, ASUS RX 470, ASUS RX 470 and some more samples from other manufacturers are coming without an analog VGA output. Immediately the question arises whether it is possible to connect a monitor that has only a VGA interface, to a computer with a DVI-D video card.

Since DVI-D is a fully digital interface, to make your adapter yourself or bend extra pins in the fork will not work. The standard adapter with DVI on the VGA will also not help you, again due to the fact that the DVI-D interface is calculated only on the digital signal, so this adapter will not work.

Video card without analog exit VGA

Connecting a VGA monitor / other device to video plane

To solve this problem you will need only:

Whether there is a HDMI output on your video card;
Choose an active adapter DVI-D VGA.

Performing this simplest algorithm will save you from tedious hiking store to buy additional components, the need for which you found out along the way.

As soon as it became clear which inputs are present on the video card, it is time to choose the so-called active adapter DVI-D VGA.

This device converts a digital signal from a video card to an old good analogWith which the monitor can already work. As a result of this transformation, the image quality will not suffer or, to be quite accurate, it will be impossible to see a significant difference.

As a rule, such an adapter looks like a box in which on the one hand has an entrance under HDMI Cablewhere we plug the DVI-D cable from the computer video card, and on the other hand, the VGA output for the monitor cable, respectively.

Depending on the manufacturer dimensions of the device may vary There are also models going with the built-in small HDMI cable. HDMI is a new digital data interface in high quality, to anyway, in the future, all manufacturers of video cards, monitors and other output devices will be driven. The presence or absence of this interface on your video card will determine the need to purchase an adapter with HDMI on DVI-D. P approved adapters are often found quite in electronics stores And they will not find it difficult.

Can it easier to buy a new monitor?

Do all these design solutions are justified, because of which you have a whole system from cables and adapters between the monitor and the system unit? Of course, the design may not be the most elegant, but the ability to connect the monitor with VGA to a computer with a video card having even the only DVI-D output exists. Although, with such an organization, a narrow place will be an adapter with DVI on HDMI (provided that there is no exit under DVI on the video card). Anyway, it will be in any case cheaper than to acquire new monitor or video card.

Here you may encounter two main problems:

The price of your chosen device;
The absence of the device you need in the nearest stores.

If the first problem can be competed, searching for models without cable on the Internet (as a rule, they will be cheaper), then with the shops not everything is so rosy. Since the DVI-I interface is more common that can work with both a digital signal and analog, find components for its exclusively "digital" fellow becomes not easy. Most likely, you will be told that there are no such devices in nature and will be offered to buy a new monitor with DVI-D. Therefore, the most correct option will be ordered such an adapter via the Internet or buy it again through online stores, it will help you to significantly save time.

Be sure to read the characteristics of the device and feedback for it.. In order for everything to work as it should, since some devices have their own features of the connection that are not always indicated in the specifications on the pages of online stores. Especially should be attentive when the adapter description does not specify that it is active. To purchase an active adapter you need, you should find the site of the manufacturer of a device that you found and carefully read the description for it.

There are no significant qualitative characteristics between existing transient data samples. Rather, each specific option will be good for use in a particular situation. For example, if you are going to make a quick-release connection, that is, it makes sense to use an adapter with a built-in cable. If you are going to configure the connection between the monitor or the projector once and do not touch it anymore, then it will be reasonable to use the adapter only with the outputs under the cables, this will allow you to choose the cable suitable in length.

We tried to make a description as good as possible so that your choice is unmistakable and conscious, but because We might not have been exploited by this product, but only on all parties felt, and you will buy it, try on your review, your feedback can make this world better if your feedback is really useful, then we will publish it and give it You have the opportunity to make the next purchase on the 2nd column.

The development of technologies in the modern world does not stop for a second. Modern technique constantly opens up new features for consumers and opportunities. However, not only new functionality is important. First of all, a clear understanding is required how to use new devices.

After analyzing thematic forums and sites, it can be understood that big number Users do not know about the methods of connecting monitors with a VGA port to a video card with a DVI-D output. Inexperienced people often receive advice from the same, not to the end of aware of lovers, resting on their, often unsuccessful, experience. Usually offered to buy a DVI-D VGA adapter, it motivating it is cheaper, and not practicality.

But the adapter of this type is unlikely to work at all, so it is recommended to use DVI-D in a VGA, and not the so-called adapter with DVI on VGA.

In order to understand all the intricacies of connection of this type, you need to understand the principle of operation.

How does a DVI-D connection work?

That translated from the English "digital video interface" is used to connect and synchronize the video between the video card and the monitor, TV, or any other display device. DVI-D is a technology that allows you to save the picture quality when switching from analog to digital signal. This type of connection will be given the maximum clarity of the image. It is important to note that this type of connection transmits an exceptionally digital signal. Connection using DVI-D is the main mass digital TVs A new generation and maximum issues a 2K permission.

This technology began to be actively used by manufacturers of advanced televisions and monitors, which created a lot of problems with a variety of owners personal computers. This is due to the fact that many users are still forced to use the obsolete VGA connection.

What is a VGA connection?

VGA (Video Graphics Array) is an image transmission technology that has been preserved since the last century, it is still used by some users. This type of connection is designed to transmit an analog signal. Best qualitywhich is available at a VGA connection is a resolution of 1280 × 720, other HD words. No 2K resolution, as well as image transmission in 3D format, do not have to talk.

At the moment, most of the manufacturers of playback devices abandoned this technology, considering it outdated. That is why the video cards of new models are equipped exclusively DVI-D port, but the overwhelming weight of users does not always want to change the monitor on the first requirement, and still use the playlials with the VGA port. That is, just so connect the old monitor without any linings and loss of image quality is impossible. Experts recommend using multiple connection techniques, however, in order to find an effective way, I need to figure it out in the process itself. What we now will go.

DVI / VGA adapter do it yourself

Due to the fact that technologies work through different ports and relate to different generations, the user must clearly understand that the type of signal transmitted from one device to another is also different. That is, a digital-analog converter is required for stable use of the playback device, and not made by a DVI / VGA adapter with their own hands or bought on a flea market. After all, the device of this type is simply unable to convert a signal from analog in digital and / or simply will not work, or the user will not be able to obtain images of the desired quality.

Types of adapters

We will pay attention to the types of adapters that advise to purchase users of thematic forums, sites and other all possible sources:

an ordinary adapter with DVI on VGA;
adapter VGA / DVI-M;
dVI-F / VGA-M adapter.

The price of such devices is extremely small, but the overwhelming majority of users believes that it is much easier to use the DVI-D VGA adapter than to change the old video card, buy a monitor with suitable port, or look for a better sentence. However, this is not quite true. The cost of the adapter with DVI on VGA ranges from 2 to 5 dollars. And in fact, the buyer receives an absolutely useless adapter at the exit, so that, like many of his comrades in misfortune, surprise: why nothing works. So where does the reason for the irreparation of VGA DVI adapter? We will answer this question now.

Pinout connectors

Knowing the deployment of ports, the masters of dubious order came to the conclusion that by connecting certain connectors, they will get a beautiful DVI-D / VGA adapter!

And on the fact, if you know how to know the path data scheme, it is immediately clear that this device Can not function at all! If you look at the port, it becomes clear that there are no pins in DVI, which is responsible for the transmission of an analog signal.

In fact, this answer can be easily found in world Wide Web: On each topic on this issue there is a post in which the author writes that everything seems to be connected, but does not work. But if the author figured out that the connection transmits signals of different types, I knew: the signal must be converted. That is, simply the connection of two different ports will not help. Such a solution to the issue is sufficiently distributed on the Internet, but it will not work - one hundred percent.

DVI-D / VGA converter

The only one possible method Connections will be a DVI-D / VGA converter. Of course, its price is higher than that of the adapter, however, we have already found out that it is better to pay extra, how to just throw out a few dollars, as they say, to the wind. The adapter with DVI on the VGA can convert an analog signal into digital, without which the user will not be able to connect any gadget. The principle of operation of the DVI-D to VGA converter in converting a digital signal to analog.

What do we have in the rest? The first: the user needs to pay attention only to the opinion of professionals who have sufficient competence. Trust the Soviets due to the cheapness of solving the problem, or because of the popularity of the method it is not worth it - it is fraught or meaningless loss money, or waste precious time.

Secondly, if it is obvious that this method of solving the problem does not function from the overwhelming majority, it means that it is necessary to understand why it does not work before taking sustainable solutions and hope that in a particular case everything will work. That is, of course, you can try to buy an adapter with DVI on VGA and save money, hoping for an unlikely result. But it is better to buy a converter that guarantees the performance of the connection.

We hope that the article helped readers to understand the question of how the adapter works this type. The only output is to purchase a special signal converter and do not worry my head, and the adapter will not be able to help.

Term DVI-D VGA - Connection Mode Designation system Block to a computer monitor, TV. This concept is also actively used to designate adapters. With their help, the old models of PC monitors equipped with analog connectors are connected to new video cards. Correct connection provides uninterrupted digital signal transmission.

The type of connection under consideration has several important features. First of all, it is impossible to exclude compatibility problems. Not always to use a special adapter allows you to solve the emerging failure. The price of the adapter is relatively small - from $ 2 to $ 5. Experts recommend abandoning the use of adapters, preferring the signal converter.

DVI abbreviation is decrypted as Digital Visual Interface, which is translated from the English-digital video interface. This connector was created to transfer the video signal to projectors, computer monitors, televisions and other techniques that can display graphic content. DVI-D adapter - digital connectionavoiding quality loss due to digital signal conversion into analog.

The interface feature is that it provides data transmission with maximum resolution. Therefore, a high-quality and natural image is displayed on the screen. The signal is played only in digital format. Separately, we note that the DVI-D connection is used on digital liquid crystal screens. Maximum supported resolution - 2048x1536 pixels.

The modification of the DVI-D interface was appreciated by leading organizations that are engaged in the production of monitors and televisions. Users working with computers because of this faced difficulties. The VGA interface began to gradually leave the mass appeal. Therefore, it was necessary to acquire adapters.

Features of the connector VGA.

VGA interface - video transmission connector. Computer monitors, video cards were equipped with this interface. To a greater extent, it concerns old devices that were released in the 80-90 years of the last century. The VGA connection is designed to transmit analog signal. Maximum quality - HD.

As for Full HD or reproduction of 3D files, it is impossible to achieve this with VGA. The interface in question is considered an outdated signal transmission method. Therefore, it is rare enough. New GPU modules are equipped exclusively DVI-D interface. Users are not in a hurry to part with monitors that are connected to the Systemster via VGA. Therefore, there are compatibility issues.

The only way out of the current situation is the DVI TO VGA adapter. If you compare the technical description of the connected connections, you can conclude that the signals are transmitted in different formats. If the interface set on the technique used does not coincide, then you should buy a high-quality digital-analog converter. This device is capable of solving the problem.

Consider that the VGA interface is classified for three additional subspecies. Now we analyze the features of each of them:

DDC1 is able to ensure the transmission of information unilaterally. The video card will determine the information on the cord, and also identifies the DDC monitor connected to this component.
DDC2 - specifications This connectivity suggests that data exchange will be carried out in bilateral manner. The monitor broadcasts information on the PC. The computer automatically adjusts the settings for the connected device.
E-DDC is the most effective subspecies. Information about the connected device is saved in the interface memory.

With the features of VGA and DVI-D, they figured out, and now we analyze the problems of compatibility and how to solve them.

Compatibility DVI-D and VGA

Comparison of signals coming from dVI-D connector The VGA interface allows you to make the right conclusions regarding the characteristic differences between these ports. To configure the correct connection, you must use adapters. Special adapters allow you to transmit a digital signal to a monitor that supports analog standard.

An alternative way to solve compatibility issues is a DVI-D to VGA Converter signal converter. In order not to encounter various difficulties already postfactum, you need to study the issue of acquiring an optimal converter in advance.

The main advantage of adapters is a minor price. There is only one small nuance. No contacts C1-C4 - rectangular holes on the port of DVI-D - the cause of compatibility related problems is caused. If even the monitor still sends the signal, then the image is unlikely to appear.

The low cost of adapters is the reason that users acquire these devices to configure the connection of the old monitor to new video card. In some situations, you can connect VGA to the DVI-D interface. However, it is rather an exception than the rule. It is the pinout that becomes the absence of a signal.

Converters

There are many different modifications of DVI-D converters on VGA. Mostly for these devices, an independent power source is required. This necessity is explained by the fact that the device has a not quite typical design. Cannot be called this adapter Adapter, as it is rather a full-fledged device with an inside board.

It is this feature that significantly increases the cost of the device. Do not attempt to save on the acquisition of the converter. Because it can cause incorrect connection. Converter function - data transmission from a modern GPU module to an outdated model of a TV or computer monitor. Often inexpensive models TV are used as a PC monitor or laptop.

The presence of a converter may also become mandatory condition Connecting old projectors. However, most of its device is equipped with hDMI interface. This connector also works with a digital signal. Therefore, there should be no problems with synchronization with a modern GPU module. Additional adapters in such situations are not required.

Consider the signal conversion algorithm. If you analyze the device accessible to purchase, you can find adapters with the following properties:

Support dVI-D connections To the monitors and screens of VGA with a resolution up to 1920x1200 pixels. Minimum resolution 800x600 points;
Transducer input - 21 pin, and output - 15 pin;
Maximum frequency - 60 Hz;
The length of the wire of the converter can reach one and a half meters;
Price - from $ 6.

Remember. Converter - unidirectional device. This means that it is capable of converting an exclusively digital signal into analog. Reverse conversion is not possible. Therefore, when you need to connect the GPU module with the VGA connector to the display or DVI-D TV, you have to use the reverse converter. However, consider that with such a connection to achieve high Quality The translated image is impossible.

When you choose a converter, consider the fact that this device may be incompatible with the technique used. Remember that for the correct operation of the converter, a separate power supply will be required. The audio signal will be displayed using an additional cable. In those situations where the cable that provides a PC connection and a monitor or television, a long less than one and a half meters, connect it to the power source is completely optional.

So that all the elements of the connection system are correctly functioned, it is desirable that the connected output device has the same frequency as the converter. Use the displays whose diagonal does not exceed 40 inches. Otherwise, stripes may appear on the screen.

If the converter converts a signal not only with DVI-D on VGA, but also works with other formats, then you should buy a multifunctional device that supports almost all popular interfaces.

What is better - DVI-D or VGA

If you compare these connectors, you can come to the conclusion that to a certain extent they are equivalent. These interfaces are noticeably losing HDMI. Since they are not able to provide simultaneous transmission of audio and video signal. However, in any case, working with DVI-D will be slightly more convenient than with VGA. This is a newer interface capable of demonstrating a really high-quality image.

Compare connectors to a certain degree incorrectly. The time of the invention of technologies is not taken into account. DVI-D appeared much later, so it is designed to work with more modern standards. VGA is used primarily on old output devices. Therefore, they use it extremely rare.

Note.
