What kind of connection sockets do the monitors have? VGA-ros'em: meaning, description, description. How to “tweak” the monitor and video card connector

You can also attach a monitor to your video card selection, which can also be used as an extension. Or turn on the monitor (in many cases). So, for modern LCD monitors with digital inputs, it is also necessary to have a DVI, HDMI or DisplayPort connector on the video card. Fortunately, in all current decisions there are such problems, and most often all at once. Another subtlety lies in the fact that if you need a separate unit greater than 1920×1200 digital output DVI, then you will need to connect the video card to the monitor using an additional connector and cable with Du support al-Link DVI. However, there are no longer any problems with this. Let's look at the main connectors that are used to connect information display devices.

Analogue D-Sub rose (also known as VGA-Exit or DB-15F)

This has long been known to everyone and is the primary 15-pin connector for connecting analog monitors. VGA is short for video graphics array (pixel array) or video graphics adapter (video adapter). There are connections for outputting an analog signal, the intensity of which can be influenced by various factors, such as the amplitude of RAMDAC and analog adapters, so the intensity of the image may vary on different video cards. In addition, in modern video cards, less attention is paid to the analog output, and to capture clear images at high resolutions, it is better to use vicor digital connection.

D-Sub sockets became virtually the same standard until the expansion of LCD monitors. Such outputs are often used to connect LCD monitors, as well as budget models, which are not suitable for gaming. To connect current monitors and projectors, it is recommended to use digital interfaces, one of the most common being DVI.

Rose DVI(variations: DVI-Iі DVI-D)

DVI is a standard interface that is most often used for displaying a digital video signal on PK monitors, although they are the cheapest. The photo shows old video card with three sockets: D-Sub, S-Video and DVI. There are three types of DVI connectors: DVI-D (digital), DVI-A (analog) and DVI-I (integrated or universal):

DVI-D— digital connection included, which allows you to eliminate costs through additional conversion of a digital signal to analog and from analog to digital. This type of connection provides the clearest picture possible, without displaying the signal in a digital form; you can also connect digital LCD monitors with DVI inputs or professional EPT monitors with built-in RAMDAC and a DVI input (even rare no copies, especially at once). For DVI-I, this connector is limited to the physical presence of some contacts, and the DVI-to-D-Sub adapter, which is available later, cannot be built into it. Most often this type of DVI is stuck in system boards With an integrated video core, video cards are less common.

DVI-A- This is a rare type of analogue DVI connection, designed for displaying analogue images on EPT receivers. In this case, the signal is transmitted through a dual digital-to-analog and analog-to-digital conversion, whose brightness is similar to that of a standard VGA connection. In nature, the mayge does not fade.

DVI-I— this is a combination of two described options, for transmission of both an analog signal and a digital one. This type is most often found in video cards, it is universal and with the help of special adapters, as most video cards are supplied with, you can also connect a standard analog CLT monitor with input DB-15F. The axis and adapters look like this:

All modern video cards need one DVI output, or even two universal DVI-I connectors. D-Sub are most often common (although they can be connected to additional adapters, surprisingly), but, again, budget models. To transmit digital data, use either a single-channel DVI Single-Link or a dual-channel Dual-Link solution. The Single-Link transmission format consists of one TMDS transmission (165 MHz), and Dual-Link - two, which provides the same bandwidth and allows you to display separate screens larger than 1920×1080 and 1920×1200 on 6 0 Hz, supporting even high modes Separately, for a standard size of 2560×1600. Therefore, for the largest LCD monitors with a large variety of components, such as 30-inch models, as well as monitors intended for displaying stereo images, you will definitely need a video card with a dual-channel DVI Dual-Link or HD output MI version 1.3.

Rose HDMI

Lastly, the new out-of-box interface - High Definition Multimedia Interface - has been greatly expanded. This standard ensures one-hour transmission of visual and audio information over a single cable, except for TV and cinema applications, and other PCs can use it to display video behind an additional HDMI connector.

In the photo left-handed - HDMI, right-handed - DVI-I. HDMI outputs on video cards are becoming increasingly common, and there are more and more such models, especially in the range of video cards intended for media centers. Viewing high-definition video on a computer uses a video card and monitor that supports the system without HDCP, and is connected by an HDMI or DVI cable. Video cards are not required to have an HDMI connector on board; in other cases, you can connect an HDMI cable via an adapter to DVI:

HDMI is the final attempt to standardize a universal connection for digital audio and video accessories. It has immediately lost strong support from the giants of the electronics industry (the group of companies involved in developing the standard includes companies such as Sony, Toshiba, Hitachi, Panasonic, Thomson, Philips and Silicon Image), and more there is current outbuildings With high permission, I would like one such rose. HDMI allows you to transmit protected, copied sound and images in digital format over one cable, the first version of the standard is limited to a bandwidth of 5 Gbit/s, and HDMI 1.3 expands this to 10.2 Gbit/s.

HDMI 1.3 - the specification has been updated to the standard with increased bandwidth of the interface, increased synchronization frequency up to 340 MHz, which allows you to connect high-disparity displays items that support a greater number of colors (multi-color formats up to 48 bits). The new version of the specification also supports new Dolby standards for transmitting compressed sound without loss. In addition, other innovations have appeared, in specification 1.3 there is a new mini-HDMI connector, smaller in size than the original one. Such roses are also used on video cards.

HDMI 1.4b is the only option New version What is the standard that came out recently? HDMI 1.4 has the following main innovations: support for the stereo imaging format (also called “3D”) with step-by-step transmission of frames and active eyepieces for viewing, support for Fast Ethernet connection HDMI Ethernet Channel for data transmission, reverse audio channel, allows you to transfer digital sound in the reverse direction, support for separate formats 3840×2160 up to 30 Hz and 4096×2160 up to 24 Hz, support for new color spaces and the smallest micro-HDMI connector.

In HDMI 1.4a, the stereo image support was significantly improved, new Side-by-Side and Top-and-Bottom modes appeared in addition to the modes of the 1.4 specification. And we found that the latest update to the HDMI 1.4b standard has been completed, and the innovations in this version are still unknown to the wider public, and devices with its support are still not on the market .

It is clear that the HDMI connector on the video card itself is not necessary; in some cases, you can replace the adapter from DVI to HDMI. It is cumbersome and comes with most modern video cards. Moreover, today's GPUs contain an audio chip necessary to support HDMI audio transmission. On all occasions AMD video cards There is no need for NVIDIA to use external audio cables, and there is no need to transmit audio from an external sound card.

Transmission of video and audio signals over one HDMI connector is required first on mid-range cards. Nizhny Rivniv, which are installed in small and quiet barebones that are used as media centers, although in gaming solutions HDMI is often used, which is due to the increased consumer technology with such connectors.

Rose

Progressively, in addition to the expansion of DVI and HDMI video interfaces, solutions with the DisplayPort interface are appearing on the market. Single-Link DVI transmits a video signal in separate sections up to 1920×1080 pixels, a frequency of 60 Hz and 8 bits per color component, Dual-Link allows transmission of 2560×1600 at a frequency of 60 Hz, and even 3840× 2400 pixels for the same minds for D Link DVI is not available. HDMI has the same interchange, version 1.3 supports signal transmission from separate parts up to 2560×1600 pixels at 60 Hz and 8 bits per component color (on smaller parts - 1 6 bits). Although DisplayPort has a little more maximum capacity than Dual-Link DVI, it has more than 2560×2048 pixels at 60 Hz and 8 bits per color channel, and there is also support for 10-bit color per channel when separated nosti 2560×1600, as well as 12 bits for 1080p format.

The first version of the DisplayPort digital video interface was adopted by VESA (Video Electronics Standards Association) in the spring of 2006. It means a new universal digital interface that is not licensed or subsidized for connecting computers and monitors, as well as other multimedia equipment. The VESA DisplayPort group, which is a standard, includes great electronics manufacturers: AMD, NVIDIA, Dell, HP, Intel, Lenovo, Molex, Philips, Samsung.

The main advantage of DisplayPort is an HDMI connector with support for protecting HDCP recording, although it is more suitable for connecting consumer digital devices to the base of players and HDTV panels. Another competitor could previously be called the Unified Display Interface. alternative way HDMI and DVI connector, also the main connector, Intel company, was inspired by the introduction of the DisplayPort standard

The number of license fees is important for producers, and for the use of the HDMI interface on their products, they must pay license fees to the HDMI Licensing organization, which will divide the money holders of rights to the standard: Panasonic, Philips, Hitachi, Silicon Image, Sony, Thomson and Toshiba. Connecting HDMI to a similar “cost-free” universal interface will save manufacturers of video cards and monitors decent costs - it’s clear why DisplayPort is suitable for them.

Technically, the DisplayPort connector supports up to four data transmission lines, each of which can transmit 1.3, 2.2 or 4.3 gigabits/s, for a total of up to 17.28 gigabits/s. Deep color modes from 6 to 16 bits per color channel are supported. Additional bidirectional channel for transmitting commands and other information, operating at a speed of 1 megabit/s or 720 megabit/s and serving the main channel, and transmitting VESA EDID and VESA signals MCCS. Also, in DVI mode, the clock signal is transmitted by signal lines, not directly, and is decoded by the receiver.

DisplayPort has the option of protecting content through DPCP (DisplayPort Content Protection) copying, developed by AMD, and using 128-bit AES encoding. The video signal that is transmitted is not available from DVI and HDMI, but their transmission is allowed according to the specification. on Narazi DisplayPort supported maximum fluidity data transfer 17.28 gigabytes/s and separate capacity 3840×2160 at 60 Hz.

Main display ports of DisplayPort: extended and extended standard; support RGB formats ta YCbCr; color color adjustment: 6, 8, 10, 12 and 16 bits per color component; full signal transmission at 3 meters, and 1080p at 15 meters; support for 128-bit AES encoding DisplayPort Content Protection, as well as 40-bit High-bandwidth Digital Content Protection (HDCP 1.3); greater throughput when paired with Dual-Link DVI and HDMI; transmission of multiple streams over one connection; Compatibility with DVI, HDMI and VGA with additional adapters; simply expanding the standard for the consumption market that is changing; external and internal connection (connecting an LCD panel in a laptop, replacing internal LVDS connections).

The updated version of the standard is 1.1, it appeared through the river after 1.0. These innovations include support for HDCP copy protection, the importance of watching stolen content from Blu-ray and HD DVD discs, and support for fiber optic cables in addition to the most modern ones. The remainder allows you to transmit the signal to even larger stations without wasting any money.

DisplayPort 1.2, approved in 2009, doubled the throughput of the interface, up to 17.28 gigabits/s, which made it possible to support higher data outputs and refresh rates. screen and glin color. Also, 1.2 itself introduced support for transmitting multiple streams over one connection to connect multiple monitors, support for stereo imaging formats and color spaces xvYCC, scRGB and Adobe RGB. There have been changes to Mini-DisplayPort connectors for portable devices.

The full-size external DisplayPort connector has 20 pins, its physical size can be expanded with multiple USB connectors. The new type of connector can already be installed on many current video cards and monitors, including those similar to both HDMI and USB, and may also be equipped with pins on the connectors similar to those that carry Serial ATA.

Before AMD bought the ATI company, it announced the production of video cards with DisplayPort connectors - already at the beginning of 2007, but the other companies introduced it at any time. Next, AMD made DisplayPort a standard connector within the Fusion platform, which conveys a unified architecture of the central data graphics processors in one chip, as well as on future mobile platforms. NVIDIA is not a competitor, releasing a wide range of video cards with DisplayPort support.

Of the monitor manufacturers who voted for support and announced DisplayPort products, the first were Samsung and Dell. Naturally, such support was given to the new monitors with a large diagonal screen size and a high separation height. Find adapters DisplayPort-to-HDMI and DisplayPort-to-DVI, as well as DisplayPort-to-VGA, which convert the digital signal to analog. If there are DisplayPort connectors on the video card, they can be connected to any type of monitor.

In addition to overused connectors, older video cards also have a composite connector and S-Video (S-VHS) with either pins. Most often, they are used to output the signal on older analogue TV receivers, and send a composite signal to S-Video, often removing mixing, which negatively affects the brightness of the picture. S-Video is better for its brightness, lower composite “tulip”, but is offended by the YPbPr component output. This connector is available on many monitors and high-definition TVs; the signal is again transmitted in analog form and can be connected to the D-Sub interface via the cable. However, with today's video cards and monitors, it simply doesn't make sense to use all analog connectors.

I'm flying, friends and regular readers! For correct operation of the monitor with the computer, it is necessary to connect it correctly. Monitor ports, as well as video card ports, vary.

From this article you will find out:

Today we will look at what kind of video connectors there are for connection, their types, as they are called correctly, each of them.

VGA (D-Sub)

The oldest standard, designed as far back as 1987 by IBM for PS/2 series computers. If they had a graphics adapter with such a connector, they could view an image up to 640x480 pixels in size. This separate screen structure is also designated by the abbreviation VGA.

Over the years, monitors have become larger diagonally and their separate components have grown, so the analog port has continued to be widely used until recently, including on rare crystal monitors.

Features of the VGA interface

• For branding, the blue color is important;
• Transmitting only a video signal (to transmit sound, use an audio cable to connect to the sound card);
• Support for other devices next to monitors - for example, projectors.

Given the wide spread of knowledge, it is still too early to “grab” such a standard: in the 30 years of our existence, a colossal number of crazy devices have been released, many of which can be exploited for at least a dozen more.
Thus, monitor manufacturers are gradually implementing this format, which is becoming increasingly popular. You won't find anything in top video cards. And the axis of the budget graphic speedy devices of this port, as before, continues to be victorious, regardless of the song for a short time.

HDMI

Today, one of the most popular and popular interfaces is important: HDMI

We produce both monitors, RC TVs and plasma panels, as well as laser projectors, TV receivers and other video equipment. Features of the format:

• There is no color marking;
• There is a range of types of HDMI connectors with different dimensions;
• Transmits both images and sound, including 3D effects with support for separate images up to 4K;
• When the cable is extended up to 10 meters, no additional signal boost is required;
• The interface capacity is up to 48 Gbit/s.

Whether your computer or laptop, as well as a monitor or other information display device, has an HDMI connector, all connections depend on the selection of a cable that simply cannot be inserted correctly.

DVI

Digital-analog interface, designed in 1999. For 20 years, having recognized many changes, you will continue to widely use computer and video technology. Features of DVI:

• Let us mark ourselves with white or zhovtim;
• Transmits images separately up to 1920x1080 (Full HD);
• There are a number of modifications that differ from each other by the type of locking key and are not insignificant;

• Supports signal transmission through cable up to 61 m without the need for an additional booster;
• There is a great difference in the signal before cross-coding when compared to HDMI, which requires the use of electromagnetic compensation devices.

BNC

Coaxial radio frequency connector, which serves to connect different equipment to each other. Equipped with a bayonet-type lock and vikoryst coaxial cable with a diameter of up to 8 mm, with a fork support up to 75 Ohm.

We use it widely for laying local measures or, for example, connection satellite dish to the TV tuner, protection from the sphere of transmission of the video signal from the video card to the monitor without actually removing it.

It’s hard to see this option: it’s unlikely that you’ll be able to find a current monitor or graphics adapter that has such a port.

Display Port

Standard for digital monitors, praised in 2006. As of today, the newest and most complete of all overinsurances before standards. You can use it to connect to a computer as a monitor or a home theater. Interface features:

• Support up to four monitors simultaneously and many independent streams;
• Data transfer speed up to 21.6 Gbit/s;
• Maximum image separation up to 8K;
• The use of this port is free of DRM (copyright protection) conditions, which complicates the transfer or copying of data.

Other foods

It is logical that the answer is clear: Display Port is the most convenient and corresponds to all possibilities.

The DVI and HDMI drives did not have an unambiguous opinion, but HDMI has gained great popularity. And VGA, being morally outdated, is not worth looking at seriously.

When purchasing a new video card, you may find that the old monitor does not have a connector suitable for connecting a monitor: for example, the display is connected via DVI, and you added a heavy graphics connection to a pair of HDMI slots.

In this case, the monitor is still working “like an old one”, and you don’t want to change it yet.

Don’t get confused: there are no adapters, with the help of which you can connect physically absurd connectors.
In this case, what is needed is not an adapter, but the adapter itself (the price difference is only a couple of dollars), which will ensure adequate transmission of the RGB signal without interference.

How to recognize roses? It’s even simpler: all the stinks are on the table, so it’s simply impossible to confuse them. It is enough to find a picture of all current ports on the Internet in order to remember their appearance again and again.

And still: is it on the USB monitor and what is it using to transmit the video stream? Experiments were carried out, but such technology has not been expanded, since the parameters do not reach other standards.

Monitors should be equipped with them for the ability to connect additional equipment: for example, a fan or a lamp, so as not to occupy the computer’s external ports.

Also, the Raju will know about the monitor. You can read about those where it is best to buy components.

That's all. As you have supplementary food. Don’t hesitate to ask them in the comments. I will be happy for anyone to share this publication with social measures. Till tomorrow!

To ensure that your monitor and computer work at the same time, be sure to check the specific cord that fits into the connectors on both the monitor and the system unit.

Now, let's figure out what kind of monitor connectors are used for connecting displays to a computer.

Types of monitor roses:

VGA (or Video Graphics Array)– these are analog sockets used for connecting a monitor to the system unit. Tsey standard It was created by a company called IBM back in 1987 specifically for the PS/2 series PC. Before the speech, they also had a video payment with a similar name. The size of the separate building is small - 640x480 pixels.

The maximum separation without loss of brightness in the VGA format reaches 1280x1024 pixels, with which the maximum picture refresh rate is 75 Hz.

DVI(Digital Visual Interface)– the world’s first digital video interface, released in 1999. The maximum output of this format reaches 1920x1080 pixels, due to the fact that more advanced and extremely expensive graphics cards are used to support the ability to transmit images in dual-channel mode, then And the separate size increases noticeably and reaches icons of 2560x1600 pixels.

The DVI-I connector supports the ability to transmit not only digital but also analog VGA signals.

Well, since DVI is far from being the most compact connector, Apple has created a new version of Mini DVI.

HDMI (High Definition Multimedia Interface)– a new high-quality multimedia interface that entered the digital device market in 2003.

This is the same as DVI, but there is a different version called Mini HDMI.

DisplayPort (DP)- right away new look roses, which were divided in 2006. It is a replacement for the DVI standard, although the task is not as simple as it might seem. Head exceptional specialness this interface These are those that offer the ability to simultaneously connect multiple monitors that are sequentially connected to the same system.

If you connect to a DisplayPort connector, you can see “DP++”, which means that if you use adapters, you can easily connect monitors with interfaces such as HDMI or DVI.

Hello, dear readers! Today I would like to talk about ways to connect a monitor to a video card - about connecting video cards. Today's video cards have not one, but several ports for connection, so that it is possible to connect more than one monitor at the same time. Among these ports are both old and rarely revised, and current.

VGA is short for video graphics array (an array of pixels) or video graphics adapter (video adapter). What appeared back in 1987, 15-pin and, as a rule, blue color, intended for outputting a strictly analog signal, the strength of which, apparently, can be affected by a number of other factors (double-draw, for example), including the video card itself, therefore the image brightness through this port on different video cards may vary slightly.

Before the widespread expansion of LCD monitors, this connector is not the same possible options connecting the monitor to the computer. Vikorist to this day, but only in budget models monitors from low permission, as well as on projectors and other game consoles, for example xbox consoles the rest of the generation View from Microsoft. It is not recommended to connect via a new Full HD monitor, otherwise the picture will be blurry 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 a digital signal that is replaced by VGA. Suitable for connecting high-definition monitors, TVs, as well as modern digital projectors and plasma panels. The maximum cable length is 10 meters.

The more separate the pictures are, the smaller they can be transferred without wasting space (without the need for special equipment).

There are three types of DVI ports: DVI-D (digital), DVI-A (analog) and DVI-I (combinations):

To transmit digital data, use the Single-Link or Dual-Link format. Single-Link DVI replaces one TMDS transmission, and Dual-Link doubles the bandwidth and allows you to display a separate screen larger than 1920 x 1200, such as 2560 x 1600. Therefore, for large monitors with a large number of components or for displaying stereo images, you will definitely need at least DVI Dual-Link or HDMI version 1.3 (about a few times lower).

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 over one cable at the same time. Initially developed for television and cinema, and later gaining widespread popularity among PC owners. 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 failure to standardize universal connection for digital audio and video add-ons, thereby taking away the strong support from the electronics giants (companies such as Sony, Hitachi, Panasonic, Toshiba, Thomson, Philips contributed to the development), and as a result - There are current devices for displaying images For high-quality applications, you may want one HDMI output.

In addition, HDMI, like DVI, allows you to transmit copy-pasted sound and images in digital form over one cable via HDCP. True, to implement this technology you need a video card and a monitor, thank you! - encouraging qiu technology, yak axis. I know again, at the moment there are only a few versions of HDMI, here’s a short summary of them:

DisplayPort

Having applied for an add-on to DVI and HDMI, since Single-Link DVI can transmit a signal separately up to 1920x1080, and Dual-Link up to a maximum of 2560x1600, it also allowed 3840x2400 for DVI, which is not available. 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, before speaking, is obligatory, as it is about 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 can see, 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 old monitor with only one VGA input.

Before speaking, it is true that 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 transmitted 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 older video cards, there is sometimes an S-Video connector, or, as it is also called, S-VHS. Call your vikorist to output an analog signal on an old TV, using the yakist. transmitted image It is sacrificed to the widest 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).

So, you bought a new monitor for your desktop PC - what should you do with this unit now? How to connect the monitor to the computer? In fact, it was necessary to supply the power supply even before you chose the option that matched the characteristics and went to the store to pay for it. Even if it’s already under your table system unit, it is necessary to select a screen that comes from these sockets for connecting a monitor, which is already in motherboard Either you see it or buy it additionally.

Connectors for connecting a monitor

Well, now let's go in order. Now, as you can already understand from what has been said, you can connect the monitor to the computer:

• Or to the motherboard of a PC with an integrated video card, to which there is a video input.
• Or to a discrete one with an additional video card installed.

Of course, for the better ones, I’ll simmer the vidyukha, or better, two, and also with water cooling – ale tse topic. And here we need to point out which connector for connecting the monitor is located on the back panel of the computer case. Most often the old VGA, DVI

Either DisplayPort or HDMI

To better convey the picture more beautifully, it is imperative to choose the other two. You can read the report about roses. Well, we wondered which one of them is in the system unit, after which we select a monitor with the same appearance, so that the new one has the same connector and cable, or, at the very least, an adapter. If the PC is immediately installed and the video card is installed, then we focus on those connectors, which are on the discrete one, the fragments may become damaged. Below in the picture green color seen in roses on the inserted card from the motherboard, in red – on the installed card.

And this is what the axis looks like: there are sockets for connecting to the monitor. This includes HDMI, DVI and D-Sub (also known as VGA).

Then the entire system unit with this monitor can be connected via VGA or HDMI - you only have to choose the option we like, and especially HDMI, and connect them with an output cable.

After connecting the monitor, for correct display of the picture and color, you will need to install the drivers that are included on the CD.
