Does the adapter DVI D VGA works. Adapter DVI-D VGA: We are talking about features, types and possible problems that may occur when used. DVI-I TO VGA - differs from presented on the showcase, but works. Fully satisfied

The term DVI-D VGA is the designation of the method of connecting the system unit 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. The DVI-D adapter is a digital connection that allows you to avoid 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 The interface in question is considered an outdated signal transmission method.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 comparable technical description Considered connections, it can be concluded 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:

  1. 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.
  2. 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.
  3. E-DDC is the most effective subspecies. Information about the connected device is saved in the interface memory.

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

Compatibility DVI-D and VGA

Comparison of signals running from DVI-D connectors to 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 the 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. It is impossible to call this adapter adapter, since 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. Very often, inexpensive TV models are used as a PC monitor or laptop.

The presence of a converter may also be a prerequisite for connecting old projectors. However, most of its devices of this type are equipped with an 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:

  • Supports DVI-D connection to monitors and VGA screens with 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, it is impossible to achieve high quality translated image.

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 output using extra 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.

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:

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

The fulfillment of this simplest algorithm will relieve you from tedious trips to the 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 is input under HDMI cable, where we connect 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 qualityFor one way or another, in the future all manufacturers of video cards, monitors and other color output devices will go. 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?

All these design solutions are justified, due to which you will have a whole system from cables and adapters between the monitor and system block? 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). One way or another, it will be in any case cheaper than to acquire a new monitor or video card.

Here you may encounter two main problems:

  1. The price of your chosen device;
  2. 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 It 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.

The term DVI-D VGA is most often called small devices (adapters), with which old monitors with analog connectors are connected to on computers transmitting a digital signal.

A feature of such a connection is not quite one hundred percent compatibility, due to which far not every such adapter actually works. And, although these devices are worth not too expensive - On average, about $ 2-5 - in most cases it is better to give preference to another device called a signal converter.

Features DVI-D and VGA connectors

The DVI port possess the computers and laptops that support special technology - Digital Visual Interface or "Digital Interface". She enjoyed to transfer video to peripherals Data output - from televisions and up.

The use of technology allows you to receive a signal with the best quality that will not be able to convey with the help of an outdated current interface. For comparison, maximum resolutionSupported by Video Graphics Array technology is only 1280x1024 pixels. For DVI-D similar the indicator is 2560x1600 pixels.

New DVI technology is already used practically on all modern monitors and output devices. However, the transition to a newer and perfect way Data transfer created a certain problem to users of those monitors that only have a VGA connector.

After all, in the 2000s most even enough large screens With a diagonal of 22-24 inches were completed only by old ports. And you can connect them to a modern PC, only if you use a special adapter for this.

There are 3 types of DVI connector:

    providing only analog data transmission DVI-A interface;

    for data transfer and digital, and in analog format - DVI-I;

    digital image only - DVI-D.

Due to the fact that computers transmit a picture in a digital format, most of the modern video cards have only one type of connectivity - DVI-D. Outdated, equipped with DVI-I interfaces, can be connected using a special cable.

Provide the same connection to the VGA screen, which has smaller permissions (analog and no longer supporting even FullHD format) with simple cables Or adapters are not always possible.

Compatibility issues

If you compare the signals that go from the DVI-D port, we can conclude about their differences. And in order to properly transfer information to digital video An analog monitor can be used by adapters from one interface on another - or signal converters with the same ports. Considering the possibility of buying an ordinary DVI-D / VGA adapter, You should know about compatibility issuesWith which you have to face most users.

The main advantage of this small device lies in his price. However, due to the lack of contacts C1-C4 (4 rectangular holes on the DVI -D connector, the possibility of analog data transmission is missing. And, if, for example, from the port of DVI-I or DVI-A, such data to send after all possible, the probability of appearance Images on the monitor from the digital interface will be minimal.

The low cost of adapters leads to the fact that many users buy them for their old monitors that need to be connected to modern cards. Sometimes this method is triggered. But, due to the fact that the "pinout" (or the location of the connector) at the old and new interfaces differ, the signal may not be.

Images do not appear on the screen due to the inability to convert the signal using a conventional splitting. If the picture still occurred, most likely, the video card is still a DVI -i or DVI-A interface. That is, supports and analog data transmission.

Solution of the problem

The problem with incompatibility is quite serious - but quite solved. Due to the fact that the data may not be simply transmitted, but also transformed, the other device has been invented by specialists, called the DVI-D converter or the VGA converter.

In appearance, it really can resemble an ordinary adapter, but equipped with an additional, increasing the size of the device, module.

Fig. 6. Converter DVI-D VGA.

The device tasks includes converting a digital signal to analog. And, at the expense of a more complex design, there is such a converter several times more expensive. On the other hand, the question arises - why are sold in online stores adapters DVI-D VGA?

Answer it is easy - the reason is the incompetence of some sellers. Or, perhaps, in the desire to sell more productnot having those functions for which they buy it. In fact, on sites where reliable information about adapters and cables is indicated, other parameters can be seen in the description - the transition is carried out not with DVI-D, but from DVI -i on VGA.

Converters

Exists whole line Data converter models with DVI-D on VGA. In most cases, it requires a separate power, since the device is not a simple adapter, but a full-fledged device with a board located inside. This feature makes the converter more expensive - but it does not make sense in this case.

The capabilities of the digital signal converter to the analogue information from the modern video card with outdated monitors is included. Or the same far from new (or just inexpensive) TVs, which can also be used to display information from a PC or laptop.

You may need a converter and when connected - although most of them have long already have, which is also digital and compatible with any modern video card. For such a device, such adapters will not be needed.

Features of signal conversion

Among the converters available in the market, you can find devices with such characteristics:

    dVI -D connection support for VGA displays with a maximum image size up to 1920x1200 pixels and minimum 800x600 pixels;

    the input of the converter has 21 IDUs, output - 15 PIN;

    maximum frequency - 60 Hz;

    the length of the converter cable - from several centimeters to 1.5-1.8 m;

    cost - from $ 6.

You should know: The converter is unidirectional. I.e can convert a digital signal to analog - But not the opposite. If you need to connect a VGA video card to a DVI-D-monitor, you will need another, reverse converter. Although it will be not too high quality.

In addition, buying a converter, it is worth considering its incompatibility with DVI-I and DVI-A interfaces. Moreover, most converters require a separate power and output of audio with an additional cable. Although in cases where the cable connecting the computer and the output device does not exceed the length of 1-1.5 m, it is not necessary to connect it to the network.

It is advisable for correct operation to support the same update frequency that the converter provides. And it is recommended to use displays or TVs with a diagonal of no more than 40 inches - otherwise the stripes may appear on the image.

Important: If the signal is converted not only with DVI-D on VGA, but also to other formats, it is worth purchasing a multifunction converterSupporting several types of interfaces.

conclusions

Despite the assurances of sellers, such converters use them not. The probability of correct connection and data transmission in this case does not exceed a few percent - and, according to the assurances of some experts, is generally zero. Much more efficiently will be purchased a converter, which is guaranteed to perform its functions by connecting to analog device Output.

Usually, no one has problems finding a cheap, even a dual adapter from the DVI connector to the usual ancient analog VGA connector and connect new video card Or another modern device to the projector, monitor, TV or similar to the playing device. But all this until the user faces the problem of connecting the DVI-D connector.
The first obstacle becomes legs and contacts. In principle, they are similar to frequently found DVI-I. It would seem that cut or bend everything that interferes - and now the adapter made by their own hands. However, nothing works.

Explanation There is a simple. The DVI standard provides for the transmission and digital signal and analog. But cable types can mean the transmission of only a digital signal. Or even two channels in the figure at the same time. Naturally to the detriment of the analogue.

Look at the connectors and cables:
Mom connector:

Cable connector.

In the case of DVI-I, one digital channel and one analog channel is transmitted. Adapters ignore the entire digit and simply rebuitate the analog lines to the appropriate outputs (pins) of the VGA adapter. As a result, adapters are cheap, contain only wires and soldering.

But another case:

From the cable side:

It seems everything is similar, but the analog signal is removed completely. And in the latter case, another set of "digits" is transmitted instead of voltages suitable for VGA. There is a variant and simpler - the photo is presented in this image:

Here the manufacturers decided to limit ourselves to just with one digital channel and do not take care of the analogue at all.

So what is the problem why DVI-D adapters on VGA although there are expensive? The problem is that in the cable it is necessary to embed electronics in addition to the soldering, which would decipher the digit, in fact, drawing a picture and then it would recodle this figure into analog image. At the same time, the quality of the picture, in the case of cheap adapters, is what can be saved to do not at all do not shock the already puzzled buyers. The fact is that from the digital format the image is translated without loss, but high-quality conversion in RGB for transmission through VGA requires quite expensive resources. As a result, this is what save.

For reference. Why do you need DVI-D? Using this format of the connectors in the full version (not as on the cropped photo 5) can be transmitted a picture in permissions 2560 × 1600 and 2048 × 1536 pixels, which significantly exceeds a single-channel version, which if and can "leave" FullHD, but will do it only with the maximum A frequency of 75 Hz, which is no longer satisfied with the owners of huge 4K TVs or monitors with a similar resolution.

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 a large number of users do not know about the methods of connecting monitors with a VGA port to a video card with a DVI-D exit. 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 of the new generation digital TVs 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.

On the this 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 belong to different generationsThe 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 a 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 cause of the inspection of the VGA DVI adapter lies? 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 port data scheme, it is immediately clear that this device cannot 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.
