VGA-DVI adapter for monitor: description, purpose

Since the days of the first "Pentiums" in the computer world, a lot has changed. However, the vast majority of users use obsolete monitors with appropriate interfaces. Video cards are used quite modern. But the connectors on them do not coincide with the monitor. And what to do in this situation? Disassemble the new monitor? I would not want to. However, it is not necessary. The VGA-DVI adapter for the monitor will help here. For the last connector is even in the most modern video cards.

Classification of connectors

At a time when the world was running the first "Pentiums", there was no better connector than VGA. This is an analog connector for connecting old CRT monitors. However, many manufacturers used it in LCD monitors, sincerely wondering what this image quality deteriorates with the increase in resolution. It's simple: it's a counter of analog video output. And in 1999, a DVI connector was created . It was already digital and provided excellent picture quality at resolutions up to Full HD (1920 x 1080). And at that time such prohibitive permits were not close at hand.

However, PC monitors were improved. And soon it became clear that the standard DVI can not cope with the resolution of 2K and above. Created a two-channel DVI, which quietly supported 2K. And now the question: "How to connect an analog monitor to a digital port on a video card?" Of course, with the help of such a thing as the adapter for the video card to monitor DVI-VGA. This connector only allows you to connect the old monitor to a new video card. On the quality of the image, it does not affect in any way, because it is impossible to transmit a digital signal through an analog channel. So it is necessary to be content with the same quality. Or purchase a separate monitor, which is preferable.

How do they look?

The VGA-DVI adapter for a monitor can look like anything. Only the connectors are unchanged. And the shape of the case depends on the manufacturer. Moreover, such an adapter can look just like a bunch of wires with two connectors, if the user, knowing the circuit, soldered it himself. But for the most part it is a plastic case, in which a port and a connector are built in. And that's all. But such a circuit is the most effective, since there is no long wire that can degrade signal quality.

Often such adapters are a usual plastic "washer". At its ends are the necessary connectors. This design allows you to reduce the cost of production. It is also very convenient to use this type of conductor. For the simpler, the better. However, there are also very steep wires, which are equipped with indicators, a separate case and special software. But the sense from them is a little, in fact quality of the image they can not raise. Why then overpay?

Why choose DVI?

There are many reasons. The first and most important thing is that VGA is already an outdated format. While he still meets, but soon disappears. The newest video cards are already produced without this interface. And what will happen next? Another reason is the quality of the image. Anyway, but the analog connector can not provide a high-quality image at high resolutions. But DVI is capable of this. The third reason is that not only the video signal can be transmitted over the digital connection, but also the sound. And very good quality. This is useful when the monitor is equipped with a built-in speaker system. The DVI-VGA adapter can not make the old monitor work better. But he can solve the problem of connecting outdated displays to new video cards.

But it's not just about image quality. The outdatedness of the VGA connector also has nothing to do with it. Just use DVI much more convenient. No need to bother with adapters and other gadgets. The monitor turns into a "turn on and forget" device. Therefore, the transition to a digital image standard is very, very desirable. And soon it will become mandatory. So it's worth thinking about buying a new monitor, and do not worry about how to connect the old one.

Do I need some software?

If you use a VGA-DVI adapter for a monitor, then you do not need to use any software products to make a connection. Everything is solved on the hardware level. But if you try to connect HDMI, then you'll have to use some utilities. Although, most likely, you will not do anything. Because these are completely different types of connectors. VGA and DVI at least something similar. But HDMI and VGA are not alike at all.

Some particularly advanced models of adapters have specialized drivers in the kit, which supposedly should provide unsurpassed image quality. But all these are empty statements, because the adapter does not convert the analog signal to digital. Just in the DVI connector there is a special channel for transmitting the analog signal. But there is no such thing in HDMI. There's a solid "figure".

Where to buy the adapter?

You can buy such a thing in the salons for the sale of computer equipment. Just ask the sales consultant about such a thing as the adapter for the DVI-VGA monitor. The price for it will be just ridiculous, because there is nothing in it for which you could take a lot of money. He can afford it for everyone. Its cost ranges from 150 to 400 Russian rubles. Moreover, very soon it will be impossible to connect a monitor to the video card without such an adapter.

Many shops of consumer electronics, as well as kiosks such as "1000 trifles", also realize the implementation of such adapters. However, as for the last points of sales, the quality there is very doubtful. It is better to spend a little more and purchase an adapter from a well-known network of computer stores. These retailers value their reputation and will not realize deliberately low-quality products. Even such a minor one.

Conclusion

So, we looked at what is a VGA-DVI adapter for a monitor. The connector serves to connect an outdated monitor with an analog connector to an up-to-date graphics card. This adapter is sold anywhere and costs not so much. Everyone can buy it. That's only better to change the monitor, because in the near future analog screens will not be supported at all. Monitors for PCs with an analog connector - the last century. Now the world is ruled by a "figure". And the situation continues to change aside, extremely undesirable for analog technologies.
