Hdmi or vga which is better for gaming. HDMI vs DisplayPort: What's the difference and which is better? Which is better: HDMI or DisplayPort

We select the appropriate plug for the appropriate connector. What types of cables are offered by manufacturers "HDMI,DVI,VGA,DisplayPort" and which interface is optimal for connecting a monitor.

Previously, to connect a monitor to a computer, only an analog interface was used. VGA. Modern devices have connectors "HDMI, DVI, VGA, DisplayPort". Let's see what advantages and disadvantages each of the interfaces has.

With the development of new technologies for flat-panel monitors, the connector capabilities have become insufficient VGA. In order to achieve the highest image quality, it is necessary to use a digital standard such as DVI. Home entertainment device manufacturers have created a standard HDMI, which has become the digital successor” of the analog Scan connector. Somewhat later, VESA (Video Electronics Standards Association) developed display port.

The main interfaces for connecting monitors.

■ VGA. The first connection standard still in use today was developed in 1987 by then-leading computer manufacturer IBM for its PS/2 series PCs. VGA is an abbreviated Video Graphics Array (an array of pixels), at one time this was the name of the video card in PS / 2 computers, the resolution of which was 640x480 pix (the combination “VGA resolution” often found in technical literature means exactly this value).

An analog data transmission system with an increase in resolution only worsens the quality of the picture. Therefore, in modern computers, the digital interface is the standard.

. ■ DVI. This abbreviation oz-naHaeTDigital Visual Interface is a digital video interface. It transmits the video signal in digital format while maintaining high image quality.

DVI is backwards compatible: almost all computers are equipped with a DVI-I connector that can carry both digital video and VGA.

Inexpensive video cards are equipped with a DVI output in the Single Link modification (single-channel solution). The maximum resolution in this case is 1920x1080 pix. (Full HD). More expensive models of video cards have a two-channel DVI (Dual Link) interface. They can be connected to monitors with resolutions up to 2560x1600 pix.

The DVI connector is large enough that Apple designed the Mini DVI interface for their laptops. Using the adapter, you can connect devices with Mini DVI and to monitors equipped with a DVI connector.

connection interfaces

■HDMI. The abbreviation HDMI stands for High Definition Multimedia Interface, that is, a high-definition multimedia interface. In modern home entertainment devices such as flat-panel TVs and Blu-ray players, HDMI is the standard connection interface.

As with DVI, the signal is transmitted digitally, which means that the original quality is preserved. Together with HDMI, HDCP (High Bandwidth Digital Content Protection) protection technology was developed, which prevents the creation of exact copies, for example, of video materials.

The first HDMI-enabled devices appeared in late 2003. Since then, the standard has undergone several changes, in particular, support for new audio and video formats has been added (see table above).

For miniature models of equipment, there is a Mini HDMI interface; An appropriate HDMI/Mini HMDI cable is included with many devices.

■ DisplayPort(DP). A new type of digital interface for connecting video cards with display devices is designed to replace DVI. The current version of the standard 1.2 allows you to connect multiple monitors when they are connected in series in one chain. However, at present, there are not so many devices that have a DP port. As a direct competitor to HDMI, this interface has a significant advantage from the point of view of manufacturers: it does not require licensing fees. While for each device with HDMI you have to pay four US cents. If the connector of a computer or laptop has the designation "DP ++", this indicates that using an adapter you can connect monitors with DVI and HDMI interfaces.

In order to leave enough space on the back of modern video cards for connectors for other purposes, a smaller version of the DP interface was developed. For example, Radeon HD6800 series graphics cards have up to six Mini DP ports.

HDMI,DVI,VGA,DisplayPort

Which of these standards will be the most widely adopted? HDMI has a very high chance of success, because most devices have this interface. However, there is a new trump card in the deck of Asian manufacturers: according to official data, the Digital Interactive Interface for Video and Audio (DiiVA) provides a bandwidth of 13.5 Gb / s (DP: 21.6; HDMI: 10.21. In addition, the companies promise that the maximum cable length between devices such as a Blu-ray player and a TV will be up to 25m. No word yet on what the DiiVA interface looks like.

USB video transfer

Two years ago, it became possible to connect monitors via USB using DisplayLink adapters. However, due to the low (480 Mbps) bandwidth, a USB 2.0 connection is unsuitable for video transmission. Another thing is the latest version of the USB standard (3.0), which provides data transfer rates up to 5 Gb / s.
The DisplayLink adapter allows you to connect monitors directly to your computer's USB port.

How to connect a computer and a monitor with different interfaces.

Thanks to the adapters, there are many connection options (see table below).

Common adapters, such as DVI-I / VGA, are quite affordable. So-called converters that convert the digital DisplayPort signal to an analog VGA signal are much more expensive.

However, for example, when you connect a TV with an HDMI interface to the DVI connector, there is almost always no sound.

Is it possible to mix devices with different HDMI versions

With this combination, only the functions of an earlier version of the corresponding interface will be available. For example, if a video card with HDMI 1.2 is connected to a 3D TV that supports HDMI 1.4, 3D games will only be displayed in 2D.
Advice. Installing the new driver allows you to add HDMI 1.4 support to some video cards based on NVIDIA chips, such as the GeForce GTX 460.
Which connectors provide the best picture quality?

As tests have shown, the analog VGA interface gives the worst image quality, especially when transmitting signals with a resolution of more than 1024x768 pix. Even 17-inch monitors support this resolution today. Owners of monitors with a larger diagonal and a resolution of 1920x1080 pix are strongly recommended to use DVI, HDMI or DP.

How to connect a monitor to a laptop?

Most laptops are equipped with connectors for connecting external monitors. Connect the monitor to the laptop first. After that, using the W and KPI buttons, you can switch between the following modes.

■ Using an external monitor as the main monitor. The laptop display turns off, the image is displayed only on the connected external monitor. The best option for movie buffs and gamers.

clone mode. External monitor and laptop display show the same image

■ Practical function for presentations and seminars.

■ Multi-screen mode. Allows you to increase the size of your Windows desktop by using multiple monitors. It is very convenient, for example, when typing text in Word, to have electronic messages in front of your eyes.

Can you connect a TV to a computer?

Modern computers and laptops lack analog video interfaces such as S-Video or composite. Therefore, connecting an old CRT TV will definitely not work. However, the vast majority of flat models are equipped with DVI or HDMI interfaces, which means that connecting them to a computer is not difficult.

Netbooks, as a rule, have only a VGA output, and only those TVs that have a VGA input can be connected to them.

Is it possible to connect a monitor via USB

For traditional monitors, this is only possible with the optional DisplayLink adapter. However, there are also models on sale that connect directly to the computer's USB port - for example, Samsung SyncMaster 940 UX.

What is the maximum cable length for the monitor?

The capabilities of the cable depend on the type of connection. When using DVI, the connection length can be up to 10 m, but in the case of HDMI and VGA, it should not exceed 5 m. To achieve the maximum transfer rate.

What should I pay attention to when buying a video cable?

To ensure that nearby electronic devices do not affect the quality of the transmitted signal, purchase only well-shielded cables. When using a low-quality cable, other devices, creating interference, may even reduce the data transfer rate in some cases. As a result, an intermittent image will be displayed on the screen or an aliasing effect will appear. Gold-plated contacts prevent corrosion of plugs due to high humidity. In addition, the gold-plated contacts used in modern cables reduce the resistance between the connector and the plug, which improves the quality of transmission. But as you can see from practice: all this can be scored, on gold-plated contacts and other lobud, cheap Chinese-made cables, namely, they are supplied complete with monitors and video cards. And they do their job very well.

For reference: somewhere, music lovers were gathered to test cables. They were present with both gold-plated and platinum contacts, from $ 1000 for a lace and much more expensive. Well, the scores were given for sound quality. To determine the winner, the competition was held naturally in the dark, the manufacturer was not visible. Well, some of the organizers came up with the idea to send a signal through an ordinary iron crowbar (with which they hammer the earth). And what do you think, he took one of the prizes.

And music lovers have been explaining for a long time what a crystal clear sound comes through this cool cable. So turn on your head, otherwise I saw the guys have a cable DVI at a price more expensive than the video card and monitor combined.

To visualize information that is processed by a computer, a screen is certainly needed. On the technical side, the monitor is connected to the system unit using a cable. There are four types of cable connectors: HDMI, DisplayPort, DVI or VGA. Each of them has both its advantages and disadvantages. So what is the best way to connect a monitor? DVI or HDMI or VGA - which one is better?

High Definition Multimedia Interface

Even connecting a screen to a computer has its own standards. So, DVI or HDMI - which is better for a monitor? The choice definitely falls on the last connector. Such undeniable leadership is due to the fact that many modern development companies use it by default.

HDMI is the most popular type of interface at the moment. It is used to connect most monitors and TVs. But the use of HDMI is not limited to these devices. It provides connection of laptops, tablets, smartphones, game consoles, multimedia players. HDMI is already a standard for connecting equipment to output images of especially high quality.

Advantages of HDMI over other connection types

In order to decide whether DVI or HDMI is better for a monitor, you need to remember the advantages of each type of connection. The advantages of the second are:

Simplicity. The image is transmitted through one cable, which is very convenient, because it allows you to avoid the accumulation of a large number of different wires. Thanks to this type of interface, you can easily and quickly convert the entire multimedia entertainment system into digital form. HDMI, due to its wide format, allows you to connect many devices (for example, for home theater) using the same cable.
Compatibility. Each new version is perfectly supported and interchanged with the previous ones.
Efficiency. connection (10.2 Gb / s) provides the transfer of video fragments with a resolution of 1080. Thus, using HDMI, you can watch movies of really high quality. For gamers, this moment is important because, thanks to the high resolution, the game speed increases.

Smart and Innovative HDMI

HDMI is an all-digital format that does not require image conversion or compression. In addition, in the future, developers plan to improve this technology as well: firstly, they are working on higher resolutions and increased frequency, and secondly, the next know-how is the expanded color palette technology, which will include up to a trillion colors, but for now At the moment it is at the development stage. The latter will allow you to get a more realistic and high-quality picture.

Manufacturers and developers of this type of connector are consumer-oriented as much as possible, so a two-way connection ensures full interaction of devices with each other. This interface allows you to automatically determine the capabilities of each type of equipment in order to adjust the necessary options. HDMI has learned to control the resolution and aspect ratio of the image. The latest development of the company is Consumer Electronics Control - a technology that allows you to control playback, recording and even launching a series of commands with a single button.

display port

If you decide how best to connect a monitor - DVI or HDMI or DisplayPort - you need to know that the latter option is definitely not suitable for fans of the HD level. This interface was developed by specialists from VESA, a fairly reputable company in its field. But, despite this, many users consider the connector to be the most suitable for connecting the screen and the power supply.

However, programmers and designers, thinking about how best to connect a monitor (DVI or HDMI or D-Sub DisplayPort), will most likely give preference to the latter. And all because the main feature of this type of connection is the ability to work simultaneously with multiple monitors.

Another advantage of the interface is the absence of license fees. Another feature of the DisplayPort connector is that each color is transmitted on its own personal channel. Unlike HDMI, it has a locking mechanism and does not require screw fasteners, which maintains reliable operation. DisplayPort is also quite small.

Summarizing the above, it can be argued that the main purpose of this type of connection is to provide communication between the monitor and the computer. For TVs, this is not the best option.

Digital Visual Interface

DVI in the nineties had the status of a standard interface for connecting monitors, but soon fell out of favor due to the advent of HDMI. But still, what is the best way to connect a monitor? DVI or HDMI - which is better? DVI can be used where 4K resolution is not required. This interface supports several modes:

only digital (the difference between the digital format is that it does not transmit an audio signal, suitable for computers that do not have speakers);
only analog;
digital and analog.

Video Graphics Array

In order to fully talk about (DVI or HDMI), which is better for a monitor, you need to remember the long-forgotten VGA. It was once widely used in electronics, but is now practically extinct. A few years ago, leading IT companies finally abandoned this interface, arguing that they were planning to switch to new high speeds.

But still, VGA is still found in old computers, projectors. And if it is convenient to use it, then why should it be abandoned? After all, he served some faithfully for more than a decade.

Summarizing

How to decide on the choice - DisplayPort, VGA, DVI or HDMI? Which is better for a monitor? First of all, you need to designate the purpose of the interface for each specific connection. The best option would be, of course, HDMI, which is universal. This connection is suitable for both TV and computer.

If multifunctionality is not in the first place, then DisplayPort will be a good choice for a PC. Now the connector is supported and used by many manufacturers. VGA and DVI, as outdated, but proven versions, will also find their own, although not widespread, but widespread. And yet the most technologically advanced, innovative and promising solutions will be DisplayPort and HDMI.

HDMI today it is the most common video transmission interface in computers and home electronics. It has even recently begun to appear on business-class smartphones. It's easy to find on the back of your computer or on the side of your laptop. No multimedia device comes without it. It has long been the standard that many devices are equipped with.

It would seem that the popularity of HDMI has overshadowed all its competitors, no matter how it transmits high-definition video and even audio. one wire and is available on many devices, but it was not there. the site is in a hurry to inform you that there is one competitor who can “meet in the ring” with such a strong opponent, the name of this technology display port.

DisplayPort, like HDMI, is used on new computers and electronics, but it's not that widespread. For example, you are unlikely to find it on PCs and laptops that are used for performing everyday tasks: work in Microsoft Office, Internet surfing, simple games, reading e-books. In home electronics, it is also less common.

Both HDMI and DP carry high-end video and digital audio over a single cable, and occasionally UI updates coming out that further expand their digital capabilities.

But which is better? What can give its owner a real pleasure to use and can perceive more modern interfaces? You will find answers to these questions below, but first we suggest going back to history and following the path of development of these modern technologies.

A bit of history

Development HDMI(High Definition Multimedia Interface) was simultaneously engaged in six global giants in the world of electronics:

Silicon Image;
Panasonic;
Toshiba;
Sony;
Philips;

Version 1.0 appeared on December 9, 2002. HDMI Licensing is currently under the control of Silicon Image. The interface is paid and each manufacturer must pay for its use 4 cents for one interface. Plus, each connector must contain a company logo.

VESA (Video Electronics Standards Association) has developed and maintains the interface display port. Since 2006, this interface has been massively installed on their products by a large number of manufacturers of computer equipment and electronics. This was done in order to quickly move away from such outdated technologies as VGA andDVI. The interface is completely royalty-free.

An interesting fact is that all the companies that created HDMI (except Philips and Hitachi) are also members of the VESA association.

Main types of connectors

HDMI have 19 contacts and is produced in four variations of connectors:

Type ofA- is a kind of standard and is used on most modern devices. Type ofC and TypeD(mini and micro) - are reduced copies of the standard size and are used in portable equipment such as: smartphones, psp, tablets. Type ofE used in the automotive industry to connect the on-board computer and multimedia devices. It is protected from engine vibration and sudden temperature changes.

The DisplayPort interface has in its arsenal 20 contacts. With the dimensions of the connectors, things are somewhat more modest than for HDMI. It is produced in two variations:

DisplayPort;
Mini DisplayPort.

Despite the fact that the official specification of the connectors does not require the mandatory presence of a blocking element, DisplayPort contains it, unlike HDMI. On the last connector, only some manufacturers provide this mechanism.

Cables to HDMI

HDMI has four types of cables that have been finalized in 2010. Since the interface is quite common, finding a few cables at home is not difficult for you. Almost all users of computers and electronics will be able to do this.

Everything would be fine, but these cables are not marked with the year of manufacture and it will be quite problematic to determine whether you have a new cable (from 2010) or an old one. If you have an earlier version, be prepared for certain difficulties in video display and audio transmission.

By the way, each of 4 types cables has different characteristics:

HDMI standard: used for video transmission up to 720p 1080i;
HDMI standard + Ethernet: all as in the previous + Ethernet;
HDMI high-speed: has increased bandwidth and can broadcast video resolutions of 1080p and even higher;
HDMI High Speed + Ethernet: Same as above + Ethernet.

All HDMI cables support ARC function, which allows you to transfer audio signal between your devices. For example, from a Blu-ray player to a TV and back to the receiver.

Prior to this, everyone had to connect a second cable between devices to achieve this effect.

HDMI cables are made primarily from copper, although there is no specific material regulation. The maximum length of such wires is 20 meters. To transmit a signal over long distances, other types of cables are used:

CAT 5 (CAT 6) - 50 meters;
Coaxial - 90 meters;
Fiber optic - more than 100m.

Also used to amplify the signal active types of cables.

Cables to DisplayPort

Unlike HDMI, DisplayPort has only one type of cable, the current version of which is 1.2 capable of transmitting video with a maximum resolution of 3840 x 2160 at 60 Hz and has 3D support. In terms of audio transmission, this is a little more complicated: the cable can transmit multi-channel audio, but cannot do audio return and Ethernet data transmission.

Pleased with DisplayPort support, through the use of adapters, other video technologies: HDMI, DVI and VGA - this can help if you have to connect a device that does not have your video connector. For example, HDMI only supports DVI.

Like HDMI, DisplayPort has 2 cable types: active and passive.

Passive: Capable of transmitting a maximum resolution of 3840 x 2160 at 2 meters. This is quite enough to display the image from the video card on a computer monitor. If the cable length is between 2 and 15 m, then the maximum resolution will be 1080p, but experiments have shown that it is quite possible to transmit an image of 2560 x 1600, which is quite a good indicator.
Active: capable of repeatedly amplifying the signal and transmitting a 2560 x 1600 picture already at 22 meters, and if it is made of optical fiber (and not copper), then the image can be “delivered” to 100 meters and further.

Number of tracks of audio and video content

HDMI transmits only 1 video and audio stream, so the technology only supports 1 monitor. In today's realities, this is not enough. Suppose you are a trader and you constantly need to monitor quotes. Doing this on one display is extremely inconvenient.

Each DisplayPort interface is capable of simultaneously displaying 2 monitors at 2560 x 1600 resolution and 4 monitors at lower resolutions. This outputs separate audio tracks for each of the displays.

Which is better: HDMI or DisplayPort?

We come to the most interesting: let's figure out which is better - HDMI or DisplayPort.

HDMI was created primarily for home electronics: media and Blu-ray players, TVs, acoustics, soundbars and others. Although this interface can confuse the inexperienced user with its variety of cable markings, it can still take what DisplayPort does not, for example, take audio return over the same cable (ARC).

DisplayPort, on the other hand, was developed under computer equipment, take for example its ability to output separate audio and video for different monitors.

At the moment, DisplayPort is not a standard interface for many devices, and this is not a good thing. HDMI got bigger distribution and widespread use. Perhaps in the future, manufacturers will take into account the need to equip their devices with several interfaces, which will give more "flexibility" to the average user.

The HDMI audio/video interface standard has become very successful. This is the most common digital connection you'll find on TVs, set-top boxes, Blu-ray players, AV receivers, game consoles, camcorders, and digital cameras. Heck, it even began to appear in some smartphones.

You will also find an HDMI port on most desktops and laptops. No modern all-in-one is complete without an HDMI input that allows you to connect a game console or set-top box to your computer so you can use its display for a second purpose.

But given the ubiquity of HDMI, you may have forgotten about another digital audio/video standard, DisplayPort. While you'll find it alongside HDMI in many of the latest models, and it's been added to graphics cards as well as laptops targeted at the business user market, it rarely appears on Windows PCs aimed at mainstream consumers.

Both HDMI and DisplayPort can transfer high-definition digital video and audio from a source device to a display. So what's the difference? Is one display interface better or more flexible than another? We'll try to answer these questions with a nose-to-nose comparison of their feature sets and typical use cases. But first, let's take a look at how these two standards came about, and which entities control them.

Back to history

The HDMI (High Definition Multimedia Interface) specification was conceived over a decade ago by six consumer electronics giants: Hitachi, Panasonic, Philips, Silicon Image, Sony, and Toshiba. Today, HDMI Licensing, LLC, a subsidiary of Silicon Image, controls the specification. Manufacturers must pay royalties to include HDMI ports in their products.

display port (DP, DisplayPort) is an interface that is an accepted standard VESA (Video Electronics Standard Association) May 3, 2006 and intended for the transmission of audio, video, USB and other data at high speed.

Designed as a high-performance interface that could completely drive obsolete interfaces out of the market. Compatibility with these standards is still maintained with the help of special adapters. display port has all the same features as the standard, but is not intended to replace it.

Standard VESA implies that you do not need to deduct additional money (royalties) for using this port. Per use HDMI For example, it is necessary to deduct a minimum 4 cents and then, provided that there is a mark on the booklets and the body of the device with the inscription HDMI. If no notes, then all 15 cents.

How Display Port Works.

AT display port a completely different system for data transmission is implemented than in previous interfaces. Packet data transfer is used, like in interfaces, or ethernet. This is a big plus, since the signal is not directed to any particular device, it can be split for several thanks to packet transmission. All this allows you to reduce the number of contact pads on the connector and great opportunities for expanding the bandwidth without changing the standard. But there is also a disadvantage that reduces the bandwidth. Since the signal is encoded by the method 8b/10b, the effective throughput is 80% , a two beats out of ten are used for service information and error correction.

The interface can transmit both video signal and audio, and this is possible separately. The audio signal can be transmitted to 8 channels with quality 192 kHz 24 bit without compression.

The video stream can be transmitted from 18 bit color representation up to 48 bit, which allows you to use the interface in conjunction with monitors that have extended color gamut(with support from the signal source).

display port has a bidirectional, half-duplex additional channel for device control, transmission of service information and support VESA-EDID, DPMS, MCCS. Plus, this channel can transmit bidirectional USB signal.

DispalyPort versions, differences.

display port 1.0

Presented 3 May 2006 of the year. First version of the standard. Data transfer rate 8.64 Gbps. The cable length is up to two meters.

display port 1.1a

Introduced April 2, 2007 of the year. Got the opportunity to use fiber optic and other technologies for signal transmission. This allows data to be transmitted over long distances without signal loss. There is also support 40bit HDCP.

display port 1.2

Introduced December 22, 2009 of the year. The most important change since the first version is the doubled throughput, which is now equal to 17.28 Gbps. This made it possible to increase the maximum resolution, color depth and refresh rate of the video signal. There is support for multiple video streams from one signal source, support for stereoscopic 3D images, a significant increase in throughput AUX channel to 720Mbps, support Global Time Code (GTC ). Added support for new color spaces such as xvYCC, ScRGB, Adobe RGB 1998. Remained backward compatible with all previous standards.

Portable devices.

Embedded Display Port 1.3(for portable devices)

Previewed in February 2011 and includes new modes Self Refresh (PSR), which allow the video card to disable the interface if the picture on the screen does not change, keeping the picture unchanged in the frame buffer. This change should benefit portable devices and their battery life.

DisplayPort Specifications:

Transfer rates 8.64 Gbps (1.0) and 17.28 Gbps (1.2).

Benefits of DisplayPort over LVDS, VGA, DVI.

Large manufacturers are gradually abandoning obsolete interfaces in favor of display port.

display port has such Benefits compared to VGA, DVI and LVDS:

DP is completely free.
DP is constantly improving.
A small amount of interference and interference created by the DP cable.
Ability to transfer any data.
Smooth distribution between audio and video data.
Ability to transmit over long distances using optical fiber (since v1.1a).
Significantly higher throughput.
Multiple video streams through one connection (since v1.2).
Internal adjustment for cable length and signal quality.
The ability to transmit a signal at 15 meters, but with a reduced bandwidth (up to 1920x1080, 60 Hz, 24 bits). Transmission through a cable up to 2 meters goes at full speed.
Connector with a simple latch.

Expanded color gamut.

Wide Color Monitor Manufacturers 30bit (1.07 billion. shades) and more, for the full disclosure of possibilities, it is recommended that display port. Other ports are for transmission only 24 bit color gamut, including HDMI for PC. However, in order to fully support 30bit, you will also need a professional level accelerator AMD FirePro or NVIDIA Quadro With D.P..

On video cards, an incomplete display port, and reduced - mini Display Port (miniDP ).
