Today's article we open a new cycle of publications devoted to the equipment for switching, transformation, transformation and convert high definition signal. In this article, we will consider 4 high-quality VGA-HDMI adapters and their features.

About HDMI and VGA Briefly

HDMI is one of the most common digital interfaces designed to transmit audio and high-definition video signals. To date, this connector has an overwhelming majority of pure household and professional AV equipment, electronics, computers, laptops and other equipment. In general, this is a completely reliable, common and extremely promising interface, the development of which supports almost all the leading global brands of electronics, alternative to which in the foreseeable future, perhaps will not be.

However, despite the rapidly developing digital era, the old analog transmission interfaces of the AV signal are still common. Among them allocated to all well-known VGA. Video Graphics Array ("Array of Pixels") or Video Graphics Adapter ("Video Adapter") - Abbreviated VGA is an analog video interface developed in 1987 by IBM to display the image on computer monitors.

This 15-pin interface is sometimes called PC-RGB, D-SUB 15 or DE-15. Before the LCD displays began to be used everywhere, this connector was the most common in computer video cards and monitors. Oddly enough, it still can be seen on many video cards and motherboards, displays, TVs, projectors, gaming consoles, laptops and other AV technology.

Despite the solid age, according to the VGA specification, it may well pull permission up to 2048 × 1536 at a frequency of 85Hz! Agree, a good result for grandfather. However, it is not worth seduced, because The quality of the image on large permissions is noticeably suffering (the picture will be lubricated and fuzzy). In addition, certain restrictions on the cable length are superimposed.

At the end of 2010, a number of large companies (including Intel, AMD, Samsung, LG, etc.) agreed to bury the VGA standard by 2015 and go to modern HDMI and DisplayPort digital interfaces.
It would seem that everything is clear: the fate of the VGA was predetermined another 7 years ago.

However, it is necessary to understand that so far there is a huge number of devices with VGA connectors, let the morally obsolete, but still quite workable. In addition, some manufacturers who did not participate in the aforementioned agreement still equip the VGA connectors their devices: laptops, monitors, televisions, projectors and a large number of professional equipment (medical, studio, etc.). So we came to the main issue of our today's article ...

How to connect devices with a VGA interface to HDMI

As it is about conjugation fundamentally different types Signal (analog and digital), simple adapters do not do here. A more complex device is needed - the VGA-HDMI adapter with signal conversion chips, power, protection, etc.

This class of devices is called converters or signal converters. If they have an HDMI interface at the input or output, then they are called HDMI converters / converters. As you understand, you can convert various signals, and we will definitely tell you about them, but already in other publications. Today it will be about VGA converters in HDMI.

4 high-quality VGA-HDMI adapters

During the writing of this material, we got acquainted with a large number of similar devices. As a rule, opportunities and characteristics in all VGA-HDMI cables are similar. However, some differences are still there, and we will definitely tell about them.

To date, you can find such VGA-HDMI schemes for every taste and wallet: from the cheap Chinese crafts with Aliexpress to models of HDMI equipment known worldwide (for example, Kramer), for which you have to lay out a considerable amount. I want to immediately warn you from buying penny devices from Chinese online stores.

As a rule, they are built on cheap chips, because of what the image quality and sound suffers, as well as the number of supported permissions. In addition, they are sold without any guarantee. If the device earned you upon receipt of the parcel, it does not mean at all that it will work regularly and in the future.

For private home use Such a VGA-HDMI connection may be suitable, but if you are professionally engaged in the equipment switching or is expected to use 24/7, I strongly recommend choosing a manufacturer with a representation in your country, support and guarantee.

For review, take several VGA-HDMI converters of the average price range of a well-known and verified manufacturer, not inferior in quality and characteristics more expensive analogues. Let us dwell on the 4 VGA-HDMI adapters.
In their example, we will tell about the equipment this class and its features.

Briefly about the manufacturer: Dr.HD is known in the Russian market for more than 10 years. It has an official distributor in Moscow, a large dealer network, service center, technical support And gives a 2-year warranty.

Simple and reliable design, metal housing, at the VGA and 2XRCA input for stereo sound - left and right channels, at the HDMI output. Input permissions:

• 640 × 480 @ 60Hz and 75Hz
• 800 × 600 @ 60Hz and 75Hz
• 1024 × 768 @ 60Hz and 75Hz
• 1280 × 960 @ 60Hz and 75Hz
• 1280 × 1024 @ 60Hz and 75Hz.

Output resolution: 1920 × 1080 and 1920 × 1200 at 60Hz frequency. It is possible to enable / disable Content Protocol - HDCP.

There will be no difficulty with connecting such an HDMI converter to anyone: on the one hand, the VGA cable is connected, on the other - HDMI and power. Nic additional settings not required. Monitor (TV, panel, projector, etc.) will receive a signal from the source after 1-2 seconds.
Look inside the device.

As we said above, it is not just an adapter on jumpers. There are several signal conversion chips, nutrition, fuses. The use of polymer capacitors speaks about the reliability of the device. Made all high quality and kindly.
Go ahead…

This model is similar to its previous characteristics, but supports large quantity Video permissions:

It may be extremely helpful if you plan to switch different equipment.
Someone may not like the non-primable plastic case. Agree, the first model in the metal looked more interesting.

Please note that the audio output here is implemented through another interface - Jack 3.5mm. According to characteristics, it does not differ from the above mentioned 2xRCA connectors: here the same screen, the same division into 2 channels. The difference is only in the shape of the connector. If you wish, you can easily find on sale Jack 3.5mm cable per 2xrca and vice versa.

The CV 123 VAH model is released significantly later than Y0102H, so the scheme looks somewhat simpler due to the use of more advanced elements. In fact, it is not inferior to the predecessor, and something even surpasses it.

This model is positioned as an accessory for game console Sony PlayStation Portable, but nothing prevents using this adapter VGA-HDMI converter and with other devices. At the input, the same VGA (permission issued by this console is 480p), at the HDMI output (with a resolution to 1080p @ 60 Hz) and again audio Jack 3.5mm to connect an audio system or headphones.

A feature of this model is the Upscale function, which allows you to increase the number of display rows to 1080 at the hardware level. Simply put, you can manually increase the resolution and the quality of the digital image to Full HD.

After breaking the device, we again see separate chips for processing video and sound and other elements of the signal conversion scheme.

Judging by the fact that the PlayStation Portable console has long been outdated (it came out in 2004, and support was discontinued in 2013), it can be assumed that this converter is also far from a novelty.
Consider another model.

This is the most recent model in the range of Dr.HD. A device is performed in the form factor of a conventional adapter. Compact metal case, low power consumption, USB nutrition and the most comprehensive list of supported video permissions:

Unfortunately, the body is tightly smeared, so we could not disassemble this device. But judging by the impressive characteristics, it is safe to talk about a decent "stuffing".

RESULTS

We reviewed several converters with which you can connect the VGA source to the HDMI consumer. Displays the process of connecting and working no sense, because Much depends on the type of source and consumer used cables and their lengths, as well as the content itself. I can only assure that all the VGA-HDMI converters listed above have coped with the task without problems. What exactly the model to choose is to solve you.

The quality of the resulting picture is good, although of course, differs from the results that can be seen when switching through HDMI and DisplayPort. Use the interface to which for 30 years is still worth only when there are no other options.

The range of the brand in question there are still multi-format converters that are converted to HDMI (or from HDMI) several interfaces (VGA, S-Video, YPBPR, SCART, YPBPR, etc.), but we will tell about them in the following publications.

Hello dear site visitors site.

Most recently, I told how you can. Today, the topic is a bit similar. I will show an example of connecting the monitor to an usual computer. In addition to the main points, I will tell you what to do if the connectors on the monitor and the computer do not coincide. So let's start.

Before connecting the monitor to the computer, you must briefly understand which connectors are used for this. To date, three connectors are most popular: VGA, HDMI and DVI. That's how they look:

What is the difference between these connectors and what better to use to connect?

VGA is an outdated interfaceBut still used, especially in cheap monitors. I recommend connecting the monitor to the computer using this connector, only in cases where there are no other connectors.
DVI is good interface transmitting a very high quality picture. First of all it is necessary to use it!
HDMI is also a good interface. Usually it is used to connect to a TV computer, but conventional monitors can also be connected. Everything will work well!

Connect the monitor to the computer

First find connectors on the monitor. They are located behind. There must be one or more connections for connecting. In my case there is only a VGA entrance, so I will use it.

Now expand the system unit and inspect it. rear part. There, almost at the bottom where the video card is connected, there are signs of us connectors. Here and VGA port:

The connectors were found and selected. Now take the corresponding cable ( in my case, the VGA cable, it usually goes complete with a monitor) and connect one end to the monitor, and the second to the system unit.

After connecting the cable, do not forget to connect the computer and the monitor to the network, as well as click the appropriate buttons on devices for inclusion.

Connecting a monitor through an adapter (DVI - VGA)

In some cases, the monitor is not rich on various connectors and only available in it. VGA interface. And on the computer in turn, on the contrary, VGA is absent, but there are wonderful DVI and HDMI ports. What to do in this case? The decision of course is there!

Buy dVI-VGA adapter. It looks as follows: On the one hand, the DVI interface, and the Solid VGA. Here's as in the photo:

Insert the other side that looks like a DVI port in the system unit connector. Now with a former DVI connector comes the VGA interface. Excellent!

It remains to connect the monitor to the computer using the VGA cable. Well, we already know how \u003d)))

This can be connected to a computer and a modern TV, with the exception of only the fact that you will most likely need for these purposes. HDMI Cable and a similar connector on the system unit! On this today I have everything, it remains only wish good luck When connecting the monitor to the computer.

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 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?

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 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.

Many modern video cards and TV devices are equipped with VGA interfaces that allow you to connect the device data without unnecessary problems. It is about this type of connection and subsequent configuration, we will also tell us further in the course of the article.

Whatever actions from the described you have been taken to connect a PC to a TV, the main device in any case will be a computer.

Step 1: Preparation

Bilateral VGA cable can be purchased at any store with computer components. In this case, its length should be selected on the basis of personal convenience.

In the absence of a VGA connector on one of the connected devices, you can use the special adapter, the type of which is determined by the availability of other interfaces. One of these devices, VGA-HDMI is shown below.

Like many other varieties, the VGA cable can be made independently. However, such a wire has not the simplest structure and without proper knowledge, it is better to get ready.

The only purpose of the VGA interface is to transmitting the video signal. Such a connection type does not allow to transmit files or sound.

Based on the above, you will need external columns connected to the PC.

After completing the selection and acquisition of components, you can proceed.

Step 2: Connection

In many ways, the connection of the TV and PC is similar to the similar processor process.
