Plug in the monitor. Difference between video ports VGA, DVI and HDMI Standards for connecting to a monitor

Good morning, high-ranking mercenaries! Today I want to talk about ways to connect a monitor to a video card - about connecting video cards. Today there is not one, but several ports for connection, so that it is possible to connect more than one monitor at a time. Among these ports are both ancient and rarely recovered, and modern.

VGA out (D-Sub)

VGA is short for video graphics array (an array of pixels) or video graphics adapter (video adapter). Appeared back in 1987, 15-pin and, as a rule, blue color, designed to produce a strictly analog signal, which, apparently, can be influenced by a lot of different factors (double-draw, for example), including RAMDAC on the video card itself, so the image brightness through this port on different video cards may vary slightly.

Until the widespread expansion of LCD monitors, this connector is not the only possible option for connecting the monitor to a computer. Vikoristovuyutsya and especially in budget models of monitors with low power consumption, as well as in projectors and some game consoles, for example, in the latest generation of Xbox consoles from Microsoft. It is not recommended to connect via a new Full HD monitor, some of the image will be blurred and unclear. The maximum allowance for a VGA cable for a separate installation 1600 x 1200 is 5 meters.

DVI (variations: DVI-I, DVI-A and DVI-D)

It is used to transmit digital signal by changing VGA. Designed for connecting high-definition monitors, TVs, as well as modern digital projectors and plasma panels. The maximum cable length is 10 meters.

The greater the diversity of the image, the smaller the image can be transferred without wasting space (without the need for special equipment).

Є 3 types of DVI ports: DVI-D (digital), DVI-A (analog) and DVI-I (combinations):

DVI-D

Only digital connections allow you to save money on image quality (especially at high resolutions). It will ensure that the image is not compromised due to the fact that the video signal does not go through the analogue/digital conversion process, but is transmitted directly in digital form, as it is.

DVI-A

An extremely rare type of analog connection via a DVI port, which essentially has nothing to do with VGA. In nature there is little zonation.

DVI-I

Universal, it combines two front views. Basically, it’s no longer possible to have a VGA port on today’s TVs; all of them have DVI-I. If you need a special adapter to such a port, you can connect a VGA monitor.

To transmit digital data, use the Single-Link or Dual-Link format. Single-Link allows one TMDS transmission, and Dual-Link doubles the bandwidth and gives the ability to display separate screens larger than 1920 x 1200, for example 2560-1600. So for large monitors with a large range of components or for displaying stereo images, a minimum of DVI Dual-Link or version 1.3 (about a few times lower) is required.

HDMI

Also digital output. The main advantage of DVI is that HDMI, in addition to transmitting a video signal, can transmit a multi-channel digital audio signal. Audio and visual information is transmitted via one cable to the screen. Initially developed for TV and cinema, and later losing wide popularity among PC users. It is possible to use DVI with the help of a special adapter. The maximum extension of a standard HDMI cable is up to 5 meters.

HDMI is a major failure to standardize universal connections for digital audio and video add-ons, which will immediately undermine the efforts of the electronics giants (such companies have contributed to the development ї, like Sony, Hitachi, Panasonic, Toshiba, Thomson, Philips), ї As a result, most current devices for displaying high-quality images may require one HDMI output.

In addition, HDMI, like DVI, makes it possible to transmit digitally captured audio and video via a single cable behind HDCP. Only for the implementation of this technology you need a video card and a monitor, thank you! - what to support this technology, about how. I know again, at the moment there are only a few versions of HDMI, here’s a short summary of them:

HDMI 1.3 is the standard of the first version (1.0) with a bandwidth of 5 Gbit/s, while in version 1.3 the channel has expanded to 10.2 Gbit/s. The synchronization frequency was also increased to 340 MHz, which made it possible to connect high-density displays with a large number of colors. Nowadays it is possible to transmit compressed sound without waste like the new Dolby standards. And starting with version 1.3, mini-HDMI appeared, which is now widely used on video cards.

With the arrival of HDMI 1.4, there was an increase in stereo imaging (3D), 4K and 2K resolution (3840×2160 and 4096×2160 – similar). Micro-HDMI has been expanded for miniature devices. An important feature of version 1.4 itself is the ability to create an Ethernet connection with speed up to 100 Mbps - all over the same HDMI cable.

In addition to standard HDMI 2.0, you can see: increased bandwidth up to 18 Gbps, which, for example, allows you to transmit Full HD 3D images at 120 frames per second; Audio is often increased to 1536 kHz for the highest sound clarity; Support for monitors and TVs from 21:9 satellites has been added.

DisplayPort

Having applied for an add-on to DVI and HDMI, since Single-Link DVI can transmit a signal from a separate range up to 1920-1080, and Dual-Link up to a maximum of 2560-1600, then a separate range of 3840-2400 is not available for DVI. The maximum capabilities of DisplayPort do not differ in any way from the same HDMI - 3840 x 2160, which still has unobvious advantages. One of these, for example, is those that companies will not have to pay a tax for the use of their DisplayPort devices - which, to be clear, is especially true when it comes to HDMI.

In the photo, the dark arrows indicate latches that prevent the connectors from falling out of the socket. HDMI version 2.0 does not have the same fixings transferred.

As you understand, DisplayPort's main competitor is HDMI. DisplayPort has an alternative technology for protecting data that is transmitted through theft, but it is called differently - DPCP (DisplayPort Content Protection). DisplayPort has the same thing as HDMI - it supports 3D images and transmits audio content. However, DisplayPort audio transmission is only available one-way. And the transmission of Ethernet data to DisplayPort is impossible.

The value of DisplayPort is influenced by the fact that it also has adapters for all popular outputs, such as DVI, HDMI, VGA (which is important). For example, from HDMI there is only one adapter - to DVI. So, if there is only one DisplayPort connector on the video card, you can connect an old monitor with only one VGA input.

Until then, this is how it works – more and more video cards are being released without a VGA output. The maximum length of the DisplayPort cable can be up to 15 meters. However, the maximum distance DisplayPort can be transferred to a riser is no more than 3 meters – which is most often needed to connect the monitor and video card.

S-Video (TV/OUT)

On old videos, it sometimes appears as S-Video, or, as they call it, S-VHS. Basically, it is used to output an analog signal on old TV sets, however, depending on the size of the image that is transmitted, it is transferred to a larger VGA. With a short cable connection via S-Video, images are transmitted without conversion over a distance of up to 20 meters. Nowadays it is very rare to see blurring (on video cards).

This article describes in detail the DVI connector that can be found on many monitors, TVs and other equipment. Let's delve a little into the history of this popular interface, and also look into its types and features. And it is also easy to compare DVI connectors with various progressive interfaces. This information will be useful to wealthy workers, as well as simplify the process of working with equipment and allow the elimination of various folding tools during work.

What is DVI output?

A popular connector known as DVI-out (Digital Visual Interface) is intended for clear transmission of images (video) on various devices to the digital type. As a rule, these are projectors, monitors and televisions.

This video interface was developed by the company DDWG. Often on the Internet you can find the decoding of many English letters DVI in this form - digital video interface. These words are more meaningful for wealthy business owners who are just beginning to understand the world of computers and other technology. This rose has a distinct color and shape, so why not simply prune it from other sources. Connecting the device to various equipment can be done simply, without requiring any complex professional skills or experience.

History of DVI connector

In 1999, the Digital Display Working Group officially introduced a completely new interface standard at that time called Digital Visual Interface (DVI). This development was carried out by leading representatives from IBM, Intel, Fujitsu and other leading corporations, who came to DDWG with one goal - to create a properly innovative digital video transmission interface I sent other image display capabilities to the monitor.

The advent of DVI marked the end of the VGA era, which had become morally and physically obsolete in 10 years. This allowed not only to improve the brightness of the content, but also to significantly increase the separation of the displays. It is noticeable that DVI-ports are relevant to Donina, who now wants to discover serious rivals who are gradually defeating the veteran.

Features of DVI

While DVI is used, it uses a proprietary data format that is based on PanelLink technology. The transfer of information is intended to be consistent and carried out by Silicon Image. This is where TMDS technology comes in handy when signal transmission is done differentially in order to minimize the level differences. These three channels transmit video signals at speeds of up to 3.5 Gbit per second. If you use a cable up to 10 meters long, you can transmit a picture in FHD format (1920 by 1200 pixels). If a larger cable is connected, then the separate content is “reduced” to HD format.

In certain situations, the Display Data Channel (DDC) may be disabled. This will help you transfer important information about the display directly to the processor itself, which is installed in the device’s signal. This includes all reporting data and additional characteristics. Find out about the brand, production date, model, size and resolution of the display. You will receive this information by sending a signal with optimal adjustments for a specific screen. If the device does not accept the required data, it may block the TMDS channel.

HDCP support, which is a daily protection system. It is implemented in the HDMI interface. You can set different levels of content security, depending on your needs. The basic principle of HDCP is that connections to an additional DVI device exchange passwords with each other. This is how internal encryption is achieved.

Please note that the DVI port of the building transmits images inclusively. Due to the sound, it is not transmitted to this type. That's why it's necessary to talk about additional channels. It is noteworthy that today’s video cards have special adapters that make it possible to simultaneously transmit sound and picture.

Types of DVI outputs

Koristuvach can be right with many types of exits. Among them:

  • DVI-A
  • DVI-I (SingleLink)
  • DVI-I (DualLink)
  • DVI-D (SingleLin)
  • DVI-D (DualLink)

It’s hard for him to guess that the songs of humility are coming out. In addition to the advantages of the design, there are also inconsistencies in the features. Power supply often breaks down between Single link and Dual link. The stench lingers and smells of darkness. The two options vary between one type and one number of contacts. The sublink of the vikorist works within an hour of all twenty four contacts. A single link, which is translated as a single link, has only eighteen contacts. If you need more separate buildings, then the first option is more suitable for you. A single link is suitable for devices that have a 1920 x 1080 resolution.

DVI-A output

This output does not provide analog transmission capabilities. The additional letter allows the author to guess that “A” means analog. There is a plug in the cable or adapter, which allows you to connect video devices (analog) to the DVI-I type output.

DVI-I output

There are two types of this rose: Single link and Dual link. The first option is based on the requirements and extensions. Additional letter I informs the community about those that are being integrated. The output is often used for digital displays and video cards. The peculiarity of this output lies in the fact that there are two transmission channels combined. The device has digital and analogue channels. The stench doesn’t just stay there forever, so don’t let it go overnight. In the future, I’ll be able to enter and behave independently, however functionally. The Dual link connector from letter I transmits an analog signal. There are as many as two digital channels. This allows the artist to reach richly beautiful images and expand his capabilities.

DVI-D output

Here the letter “D” informs about the English word Digital, which can be translated as digital. This option does not have an analog channel. With this socket, digital transmission is no longer possible. As in the front exits, here there is a division into single and subordinate. Single link cut off the koristuvach. Separateness cannot be increased more than 1920 by 1200 (at a frequency of 60 Hz). This option has only one digital channel. You cannot connect an analog monitor, nor can you use technology called nVidia 3D Vision. Prote Dual link will help you watch on a 3D monitor, increasing the capabilities of the user. There are two digital channels.

What is the difference between DVI-I and DVI-D?

DVI-I supports both digital and analog data transmission, while DVI-D does not support digital transmission.

The importance of DVI roses

DVI-A is less effective than DVI-A. To transmit an analog signal. If DVI-D is used, it will ensure the transmission of non-digital video content. This creativity is only possible with DVI-D. Next, we will come up with universal solutions that are suitable for various devices. Let's talk about DVI-I. In certain situations, adapters can be used. Ale is more than possible, if it is transferred to the winemaker of one or another device.

The adapter helps to identify the problem, or it may affect the image brightness. There are plenty of types of these devices. The following are defined: DVI – HDMI, VGA – DVI and other required devices. DVI-D and DVI-I cables can be used in dual mode (dual link). And here the building's access capacity comes into play. For this reason, add additional contacts. This solution makes it possible to transmit much more information that can be easily matched to the frequency of the monitor images that become visible. If you need to use nVidia 3D Vision technology quickly, then a dual link is simply necessary. Also, you should know that great PK monitors, which offer a great variety of functions, are compatible with a DVI-D Dual-Link connector.

Pinout of DVI outputs

Upgrading DVI connector to HDMI and Display Port

The first place among the roses at DP is at the display port. By changing the front adjustment, add the front opening. It benefits from miraculous throughput, and also unlocks a wealth of new capabilities. The attachment allows you not to waste the fruits, and also appears to be small in size. Having already begun to remove the dvi and hdmi. However, not all monitors have the same connectors that would come with this new product.

Until the changes are made to the system of their production, you will have to wait for a long time. Most manufacturers are in no hurry to use this device for their technology. That's why many current and popular models don't have DP yet. That's why dvi and hdmi haven't spent everything yet. The remaining option works wonders by transmitting digital video and audio simultaneously. The attachment can be used with popular and new models of equipment. This interface will help eliminate high levels of separation. There are shortened versions, which may not only provide exceptional throughput, but also give the client a lot more capabilities. Sound and video will not be distorted when extending the cable to 10 meters. The dvi connection will also be deprived of information and requirements. It can be used on a variety of devices, since the producers value it to better give it their edge due to its versatility.

#VGA #DVI-D #DVI-I #HDMI #DisplayPort

Interfaces that are becoming increasingly stagnant at this time:

VGA

(D-Sub)- a single analog interface for connecting monitors, which is still being developed at this time. Having become morally outdated, there is still a difficult time for active vikorists. The main problem is the need to reconvert the signal analogue format and back, which leads to loss of power when connecting digital imaging devices (LCD monitors, plasma panels, projectors). Suitable for video cards with DVI-I and a similar connector.

DVI-D

- Basic type of DVI interface. It does not require a digital connection, so we cannot use video cards that do not have an analog output. More expansions.

DVI-I

- Expanded version of the DVI-D interface, which is most often used these days. There are 2 types of signals - digital and analog. Video cards can be connected to both digital and analog connections; a video card with a VGA (D-Sub) output can be connected to either through a simple passive adapter or a special cable.
Since the documentation for the monitor states that this modification has the DVI Dual-Link option, then to fully support the maximum resolutions of the monitor (for 1920*1200 and higher) the video card and cable D VI, which is stagnant, it is also our responsibility to support Dual-Link, as new version of the DVD-D interface. If the cable is supplied with the monitor and the video card is obviously current (at the time of writing the FAQ), then no additional accessories are required.

HDMI

- adaptation of DVI-D for consumer equipment, supplemented by a digital interface for transmitting multi-channel audio. Almost all current LCD TVs, plasma panels and projectors. To connect to an HDMI video card connector with a DVI-D or DVI-I interface, all you need is a simple passive adapter or a cable with connectors. It is impossible to connect a video card only with a VGA (D-Sub) connector to HDMI!

Outdated and exotic interfaces:

Before the computer you can enter the skin of your PC. There is no need to buy a new monitor or simply move the computer to a different location sooner rather than later. In such a situation, it is necessary to turn off and connect the monitor to the computer. This article lets us know how to earn it.

The monitor can be connected to an additional DVI interface. This option is the most popular. If your computer is equipped with desktop computer interfaces, then you must be careful to ensure the clearest picture possible.

The monitor can be connected to an additional VGA interface. The VGA interface is considered obsolete. This is only valid if you have a DVI or HDMI output, and also if the monitor you are connecting to does not support other interfaces.

The monitor can be connected to an additional HDMI interface. This option is used to connect a TV to a computer, if necessary, then you can use it to connect a monitor. While laptops are rarely equipped with a DVI video output, HDMI is most often used.

The process of connecting a monitor to a computer

So, if you don’t know how to connect the monitor to your computer, then take a look at the back panel of your computer right away. Above all, at the bottom of the rear panel of the system unit you will find video outputs (DVI or VGA output, as well as HDMI).

As you know, there are video outputs in the lower part of the system unit, these are video outputs, and they need to be corrected first. There are no video outputs in the lower part of the system unit, which means that the computer is not equipped with an integrated video card or embedded graphics. In this case, it is necessary to select video outputs from the top part of the system unit (not video outputs).

Lastly, look at the back of the monitor. It is important to know the monitor without a DVI input. Ale in some of the cheapest and older models may be available. If your computer has a DVI output, but your monitor does not have a DVI input, to connect the monitor you will have to select the VGA output on your computer and VGA input on the monitor. If the computer does not have a DVI output, and the monitor does not have a VGA input, then you can quickly use an adapter.

However, as a rule, such problems do not arise. As a rule, the monitor has both a DVI and VGA input, and the choice of video interface to connect the monitor depends on the video outputs on your computer.

To connect the monitor to a computer using an additional DVI or VGA interface, you need to connect the video output on the computer and the video output to the monitor using an additional DVI or VGA cable (depending on which interface you are using) vikoristovuete). After connecting, you need to tighten the two screws that are located on both sides of the DVI and VGA cable.

These screws twist the plastic tips and twist them with your hands. If you do not secure the connections to the other screws, the cable may cause bad contacts, which may cause a problem to appear on the monitor.

If you are a victor, there is no need to tighten the screws, since the cable is not equipped with such a function. For this option, you just need to connect an HDMI cable between HDMI output on your computer and HDMI input on your monitor.

To correctly connect the monitor to the system unit, it is important to know what interfaces are on the computer and monitor. There are several different options and in appearance they differ from each other in different shapes and the number of external stitches. This knowledge is essential for choosing the right video cable. Let's look at the most advanced ways to connect a monitor to the system unit.

You can connect the monitor to the system unit using an additional cord with one of the following connectors: VGA, DVI, HDMI and DisplayPort.

Take a look at the possible options, their advantages and disadvantages, and choose the best one for yourself.

Video - How to connect a monitor to a computer

Connecting the monitor to a computer via VGA

VGA is an outdated interface that is used on inexpensive monitors. It is recommended to connect the monitor to the system unit via an additional connector except for other ports.


  1. Take the output VGA cable that came with the monitor and connect one end to the monitor and the other to the computer. Before the pins enter the groove, do not use physical force! The shape of the socket “shows” how they need to be connected.


  1. Connect the computer and monitor to the limit. Then Windows itself will install the necessary drivers and select the required separate components.

Connecting the monitor to the system unit using an additional DVI-VGA adapter

Most average monitors only have a VGA interface, but an analog input that receives video signals. Likewise, the system unit can have both VGA and DVI.For the obviousness of the DVI port, it’s better to vikoristovat yourself.

Important! In the situation that has arisen, there will only be one way to connect -DVI-I - VGA. Come get an adapter DVI-VGA . Connect an analog monitor for helpThe DVI-D connector is cumbersome, since the port does not support digital data transfer.

The adapter looks like in the photo: on one side there is a DVI interface, and on the other side there is a VGA interface.

Insert the adapter with the DVI interface side into the socket on the computer in such a way that a VGA port comes out.
