Hdmi or displayport which is better for gaming. HDMI, Display Port, VGA, DVI - which is better. Bandwidth and video streams

To visualize information that is processed by a computer, you definitely need a screen. On the technical side, the monitor is connected to the system unit with a cable. There are four types of cable connectors: HDMI, DisplayPort, DVI, or VGA. Each of them has both advantages and disadvantages. So what's the best way to connect your monitor? DVI or HDMI or VGA - Which is Preferred?

High-Definition Multimedia Interface

Even in connecting a screen to a computer, there are standards. So, DVI or HDMI - which is better for a monitor? The choice definitely falls on the last connector. This 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 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 for displaying especially high quality images.

Advantages of HDMI over other connection types

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

1. Simplicity. The image is transmitted through one cable, which is very convenient, because it avoids the accumulation of a large number of different wires. Thanks to this type of interface, you can easily and quickly digitize your entire entertainment multimedia system. HDMI, due to its wide format, allows the connection of many devices (for example, for home theaters) using the same cable.
2. Compatibility. Each new version is perfectly supported and interchangeable with previous ones.
3. Efficiency. connection (10.2 Gb / s) provides transmission of video clips 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 gaming speed increases.

HDMI intelligence and innovation

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

Manufacturers and developers of this type of connector are focused on the consumer as much as possible, therefore the 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 resolution and aspect ratio. The latest development of the company is Consumer Electronics Control - the technology allows you to control playback, recording and even launching a series of commands with a single button.

DisplayPort

When deciding how best to connect a monitor - DVI or HDMI or DisplayPort - you need to know that the latter option is definitely not suitable for HD lovers. This interface was developed by specialists from the VESA company, which is quite authoritative in its field. But despite this, many users find the connector 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 probably 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 latching mechanism and is free from screw fixings, which maintains reliable operation. DisplayPort is also quite small in size.

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 lost its relevance due to the appearance of HDMI. But still, what is the best way to connect a monitor? DVI vs 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, it is suitable for computers that do not have speakers);
• analog only;
• digital and analog.

Video Graphics Array

In order to fully talk about what (DVI or HDMI) is best for a monitor, you need to remember the long-forgotten VGA. It was once widely used in electronics, but now it is practically extinct. Several years ago, leading IT companies finally abandoned this interface, arguing that they were planning to move 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 you refuse it? After all, he served some people faithfully for more than ten years.

Summarizing

How will you decide on the choice - DisplayPort, VGA, DVI or HDMI? What's best for a monitor? First of all, you need to indicate the purpose of the interface for each specific connection. The best option is, of course, HDMI, which is versatile. This connection is suitable for both TV and computer.

If versatility doesn't come first, then DisplayPort is a good choice for PCs. The connector is now supported and used by many manufacturers. VGA and DVI, as outdated, but proven versions, will also find their, albeit not widespread, but widespread. Yet the most technologically advanced, innovative and forward-looking solutions will be DisplayPort and HDMI.

HDMI audio / video interface is ubiquitous. You will find them on TVs, digital set-top boxes, DVD and Blu-ray players, game consoles, camcorders, digital cameras, and even some smartphones.

You can also find HDMI ports on most custom desktops and laptops. Not a single modern candy bar is complete without this port, which allows you to connect a game console or digital TV receiver to your computer and thereby expand the range of possibilities for its use.

But while HDMI is ubiquitous, you may be forgetting another digital audio / video standard: DisplayPort. Although you can find it on par with HDMI in many "advanced" models of monitors, embedded video cards, and so-called "business class" notebooks, this connector is rarely found on Windows personal computers aimed at the general consumer.

Both of these interfaces, HDMI and DisplayPort, are capable of transferring high-definition digital video and audio from source to display. What, then, is the difference between them? We will try to answer this question as fully and clearly as possible, starting with the history of these two standards, as well as their copyright holders.

A brief history of the two interfaces

HDMI (High Definition Multimedia Interface) was born in 2002 as a collaboration between renowned consumer electronics giants including Panasonic, Philips, Silicon Image, Sony, and Toshiba. Today, this development is entirely controlled by HDMI Licensing, which in turn is wholly owned by a subsidiary of Silicon Image. Electronics manufacturers are required to pay royalties to use the HDMI connector in their devices.

The DisplayPort specification was developed and still remains under the control of the Video Electronics Standards Association (VESA), an impressive consortium of many manufacturers from AMD to the ZIPS Corporation. DisplayPort debuted in 2006 as part of an effort to supplant the much older VGA (Video Graphics Array, analog interface, first introduced in 1987) and DVI (Digital Video Interface, born 1999) standards previously used in computer monitors. DisplayPort is royalty free.

HDMI and DisplayPort connectors and sizes

HDMI connectors are equipped with 19 pins and are most commonly found in three sizes: Type A (standard), Type C (mini), and Type D (micro). Of these, type A is much more common than others.

The much more infrequently used Type B has an extended video channel for transmission of images above 1080p. Another type of HDMI connector, type E, is used to connect external devices to car media systems.

Most HDMI connectors are equipped with a friction stopper, which means that a tightly inserted plug ensures that the pins are securely connected. However, some manufacturers design their own locks so that the wire cannot be accidentally pulled out of the socket. Such locks, for example, for obvious reasons, are necessarily equipped with type E connectors.

Three types of HDMI connectors you are most likely to encounter (from left to right): standard, mini, micro

DisplayPort connectors have 20 pins and come in two sizes: DisplayPort and Mini DisplayPort (the latter is the connector preferred for the Microsoft Surface Pro tablet). Interestingly, the Intel Thunderbolt controller interface combines the capabilities of Mini DisplayPort and PCI Express data connections - however, this is beyond the scope of this article.

Although most full-size DisplayPort connectors have a locking mechanism that prevents the wire from being pulled out accidentally, this option is not considered mandatory by the official specification.

You can find a Micro D Type HDMI connector on some smartphones and tablets, but no electronics manufacturer other than Microsoft even puts Mini DisplayPort on their portable devices. A lock is very common on full-size DisplayPort connectors, but even Type A HDMI connectors are rarely equipped with this useful feature.

HDMI and DisplayPort cables - what they are

The biggest problem with the HDMI cable varieties is that there are currently four of them, and a fifth is on the way, which will implement the recently released HDMI 2.1 specification. At the same time, a huge number of older cables do not have markings that explain their capabilities and bandwidth.

However, using an HDMI cable that is not suitable for a specific task is fraught with problems such as transmission failures or image distortion, artifacts in the frame, picture and sound out of sync.

Let's take a closer look at the current four types of HDMI cables.

• Standard HDMI Cable:provides sufficient bandwidth for 720p and 1080i video only. Designed to connect any home devices with undemanding parameters (DVD players, satellite TV receivers, plasma and liquid crystal panels ...). A budget option for conventional signal sources and receivers. Suitable for those who do not need high quality picture and sound.
• Standard HDMI Cable with ethernet: has the same channel, plus supports additionally a bi-directional Ethernet HDMI data channel up to 100 Mbit / s. Allows the device to receive a high-speed Internet connection and simultaneously distribute the content received from the network to other HDMI-connected devices. Unlike cable, Standart supports Audio Return Channel technology, which makes it possible to transfer audio data without using any S / PDIF audio connection (no additional cable).
• High Speed \u200b\u200bHDMI Cable: provides a wider channel, capable of transmitting video with a resolution of 1080p and 4K (4096x2160). Supports Audio Return Channel technology and almost all video formats, including Deep Color and 3D. Designed to connect high quality devices (Blu-ray and HDD players, plasma and LCD panels, satellite TV receivers). Provides, however, a maximum refresh rate of only 24 Hz, which is good enough for movies but disgusting for video games.
• High Speed \u200b\u200bHDMI Cable with ethernet: supports wide bandwidth and all the same technologies as High Speed \u200b\u200bHDMI Cable, and additionally provides Ethernet HDMI up to 100 Mbps.

Make sure to buy a High Speed \u200b\u200bHDMI Cable if you intend to use it to transfer 1080p or higher resolution video from your computer or Blu-ray player to your monitor (Ethernet support is optional)

All four cable types support ARC (Audio Return Channel) technology, which allows the TV to send audio data back to the AV receiver. Without it, you would have to connect a second cable to transmit sound (note that if you subscribe to cable or satellite TV and use a digital set-top box, you can do without ARC).

The HDMI specification does not specify a maximum cable length, nor does it set limits on the material for its manufacture. Copper wire is the most popular material, but HDMI signals can also pass through CAT 5 or CAT 6 cable (up to 50 meters), coaxial cable (up to 90 meters), or fiber optic (over 100 meters), as described by HDMI Licensing LLC. ...

"Active" HDMI cables have integrated circuits built in to amplify the signal. Active cables can be longer and thinner than passive cables (the thinner the cable, the less likely it is to deteriorate and fail to bend severely if necessary).

DisplayPort cables are much easier to describe: they only come in one type!

The current version, DisplayPort 1.3, provides a sufficient bandwidth for video transmission with a resolution of up to 3840x2160 pixels with a refresh rate of 60 Hz and supports all common 3D video formats. DisplayPort cables are also capable of carrying multi-channel digital audio. On the other hand, DisplayPort cannot transfer ethernet data, and this standard does not support Audio Return Channel technology either.

Two types of DisplayPort connectors - standard and mini

By adding a simple adapter, a DisplayPort cable can link a DisplayPort source to a VGA display (this is an extremely useful option if you need to connect your laptop to an older video projector). Adapters are also available for connecting a DisplayPort source to a single link DVI or HDMI display. An HDMI cable can also be connected via an adapter to the DVI interface, but that's about it.

DisplayPort passive copper cable is capable of transferring extremely high amounts of data (for example, video with a resolution of 3840x2160) up to two meters in length. If you want to use a 15 meter passive DisplayPort copper cable, this standard will limit your potential transmission capacity to 1080p. But the specifications are conservative, and they are made with a margin, in practice, a 15-meter cable is capable of transferring enough bits to support a resolution of 2560x1600 (this is great for a 30-inch monitor).

An active copper DisplayPort cable, which feeds the signal amplifier built into the connector through itself, can transmit video with a resolution of 2560x1600 already up to 20 meters. Finally, DisplayPort fiber optic cables can be over a hundred meters long.

How many devices can be connected via HDMI and DisplayPort

Each HDMI cable can carry one video stream and one audio stream at the same time, which is enough to support only one display. This is enough if you only connect one monitor or TV panel, but nowadays many people use more than one monitor.

One DisplayPort interface can support up to four monitors with a resolution of 1920x1200 pixels each, or two monitors with a resolution of 2560x1600 pixels, with each display receiving its own independent video and audio stream. And since some GPUs are capable of supporting multiple DisplayPort interfaces, you have the ability to daisy-chain up to six compatible monitors from a single source.

So which interface is better - HDMI or DisplayPort?

HDMI was designed primarily for mainstream consumer electronics such as Blu-ray players, televisions, video projectors, and the like. When you deal with the difficult classification of cables by purpose and ability, this standard provides capabilities that are beyond the power of DisplayPort connectors. In the meantime, DisplayPort was created mostly as a general purpose interface specifically for computer displays, so this standard does not replace, but rather complements HDMI.

Unfortunately, many PC makers - especially those of consumer notebooks and all-in-ones - seem to feel that it is sufficient to equip them with an HDMI connector. We hope that this view will change as DisplayPort can provide at least as much value to the consumer as it has long been to business users.

HDMI isn't going anywhere, and we're very happy about it, but it's time for the computer industry to take a more affectionate look at DisplayPort.

Do you need DisplayPort?

As we said earlier, the HDMI standard is ubiquitous. This interface is present on almost any TV panel, and every consumer computer monitor will be equipped with it. You can also surely find it on most embedded video cards, on laptops, system units of prefabricated computers and in every all-in-one.

But monitors, desktops and monoblocks of a higher level, in addition to HDMI, will be equipped with DisplayPort connectors. As for laptops - they, of course, lack space to accommodate connectors. However, the more expensive business-oriented models will also necessarily be equipped with a DisplayPort interface.

If you plan on using your laptop with a free-standing monitor, you won't regret the small overpayment for a model equipped with a DisplayPort connector. The ability to support multiple displays at the same time and the ability to connect through inexpensive adapters to virtually any type of monitor offers significantly more flexibility than HDMI alone can offer.

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, he even started appearing in some smartphones.

You will also find an HDMI port in most desktops and laptops. No modern all-in-one device is complete without HDMI input, which allows you to connect your 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 will find it along with HDMI in many of the latest models, and it has been added to graphics cards as well as notebooks aimed at the business user market, it rarely appears in Windows PCs aimed at general 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 the other? We will try to answer these questions in a head-to-head comparison of their feature sets and typical use cases. But first, let's look at how these two standards came about, and what legal 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.

Today, the most popular interface for broadcasting digital video and audio data from a PC to a monitor (TV) is HDMI. PCs, laptops and even some mobile devices support this technology. Nevertheless, according to the statements of specialists, the HDMI interface has a serious competitor in the face of DisplayPort. What is it and what are its advantages?

What is DisplayPort? DP is one of the interfaces used to broadcast video and audio data. How does this standard differ from HDMI, which has conquered the market so far? This is what we will try to figure out.

Connectors

The first thing you should pay attention to is the connector. The HDMI interface has 19 pins, which are intended for broadcasting information. In this case, the connectors developed using this technology have 4 options:

• A. The most common form factor. It is used in almost all PCs, laptops, displays, etc. Among these four types, it is the most dimensional.
• C. Mini-variant, which is used in laptops, netbooks and tablets.
• D. Micro-variant, which is used to transfer information in portable devices. That is, this form factor can be found in smartphones, PDAs, etc.
• E. Used exclusively in automobiles. Thanks to this connector, you can connect the device to the on-board computer of the car. Among the features of this form factor, it is worth highlighting: protection against temperature extremes, moisture and vibration, which the car engine produces.

As for DisplayPort, this interface has 20 pins. Moreover, the connectors developed using this technology have only two types:

• DisplayPort. Standard full size interface. It is used in PCs, laptops, TVs. If we draw an analogy with HDMI, then this connector can be assigned an A-type interface.
• Mini DisplayPort. Reduced version of the interface. As a rule, it is found on tablets, small-sized laptops. If we talk about the characteristics, then in this regard, Mini DisplayPort is similar to the HDMI C-type connector.

One of the main features of this connector that distinguishes this interface from the same HDMI is the blocking element. It is found on almost all full-size connectors. In the Mini version, blocking is less common, since installing the mechanism on a small port is simply impractical.

Cable

The last HDMI update happened in 2010. The updated interface solved the problems with broadcasting audio and video data. The production of cables according to the old standard was discontinued. Outdated HDMI versions are no longer available for sale. However, many users have older cables. And outwardly they almost do not differ from the new ones. This can lead to a number of difficulties.

Currently, there are 4 types of cables for HDMI-interfaces on sale:

• HDMI Standard. The most common type. This cable supports 720 by 1080 image transmission.
• HDMI Standard and Ethernet. In terms of quality, the image is no different from the previous model. The only difference is that this standard, as the name implies, supports Internet technologies.
• High Speed \u200b\u200bHDMI. Supports audio and video data with Ultra HD resolution (4096 by 2160). As a rule, this cable is used by professional designers who work with computer graphics. High-speed HDMI is in demand among 4K TV owners who want to enjoy high-quality games and movies. However, the cable's Ultra HD support is lame. Sometimes the broadcast frequency can drop to 24 Hz. This is enough for watching videos. However, playing at such a low frequency is uncomfortable.
• High Speed \u200b\u200bHDMI and Ethernet. Everything that is said about High Speed \u200b\u200bHDMI is also true for this type. However, the HDMI to Ethernet cable supports Internet connection and 3D videos.

It should be noted that these cables support a special feature called ARC. Thanks to it, you can simultaneously transmit sound and image. That is, there is no need to use additional headsets.

What about DisplayPort? There is only one cable variation (called version 1.2). It is believed that in terms of quality, DisplayPort is head and shoulders above HDMI. DP cable transmits video data with a resolution of 3840 by 2160. The quality is not degraded (the frequency is kept at 60 Hz). In addition, DisplayPort is capable of delivering 3D video clips. Another advantage is compatibility with various connectors. DP cable can interface with DVI, HDMI, VGA standards.

Among the minuses are problems with the playback of the audio track. This is quite natural, because DP does not have built-in ARC. In order to correct this shortcoming, it is necessary to buy a specialized audio headset. In addition, the standard in question does not support the Internet.

Streams

HDMI interfaces do not support multithreading. This means that only one display can be output at a time. This is enough for an ordinary user. However, this functionality may not be enough for professional designers and avid gamers.

In this regard, DS is clearly superior to the competitor. After all, this standard supports multithreading. That is, information can be displayed on several displays at once. However, it should be noted that the number of connected monitors is inversely proportional to the image quality. For example, if you need to display information in Ultra HD resolution, then you will not be able to connect more than 2 screens. If there is a need to broadcast to 4 displays at once, you will have to display the picture in Full or HD format.

What to choose?

After reading the article, a completely natural question is brewing - which is better than HDMI or DisplayPort? It all depends on your goals. If you are engaged in graphics, modeling three-dimensional objects, or simply are an avid gamer, then you should pay attention to devices with DisplayPort interfaces. If you are an ordinary user and do not require much from your PC, then the HDMI connector will be enough for you.

HDMItoday it is the most common video transmission interface in computer technology and home electronics. It has even started appearing on business-class smartphones recently. It can be easily found on the back of your computer or from the side of your laptop. No multimedia device comes without it. It has long become the standard that many devices come with.

It would seem that the popularity of HDMI has eclipsed all its competitors, no matter how it transmits high-definition video and even audio one wireand 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 is able to “meet in the ring” with such a strong rival ”, the name of this technology DisplayPort.

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

Both HDMI and DP transmit high-quality video and digital audio over the same cable, and from time to time interface updates are outthat further expand their digital capabilities.

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

A bit of history

Development HDMI (High Definition Multimedia Interface) were simultaneously engaged by 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 corporate logo.

The Video Electronics Standards Association (VESA) has developed and maintained the interface DisplayPort... Since 2006, a large number of manufacturers of computer equipment and electronics began to install this interface on their products. 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.

Basic connector types

HDMI have 19 connections and is produced in four connector variations:

A typeA - is a kind of standard and is used on most modern devices. A typeC and TypeD(mini and micro) - are reduced copies of a standard size and are used in portable equipment such as smartphones, psp, tablets. A typeE used in the automotive industry to connect an on-board computer and multimedia devices. It is protected from engine vibration and extreme temperature changes.

DisplayPort has in its arsenal 20 contacts... With the dimensions of the connectors, the situation is somewhat more modest than that of HDMI. It is produced in two variations:

• DisplayPort;
• Mini DisplayPort.

Despite the fact that the official connector specification does not contain the requirement for a mandatory blocking element - DisplayPort does contain it, unlike HDMI. On the last connector, only some manufacturers provide this mechanism.

HDMI cables

HDMI has four types of cables that were finalized in 2010... Since the interface is quite common, it will not be difficult for you to find several cables at home. Almost all computer and electronics users can do this.

Everything would be fine, but only these cables are not marked with the year of manufacture and it will be quite problematic to determine your new cable (from 2010) or the old one. If you happen to 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 with a resolution not exceeding 720p 1080i;
• HDMI standard + Ethernet: everything as in the previous + Ethernet;
• HDMI High Speed: has increased bandwidth and can broadcast video at 1080p and even higher;
• HDMI high speed + Ethernet: everything as above + Ethernet.

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

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

HDMI cables are made predominantly 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 - over 100m.

To amplify the signal, more active cable types.

DisplayPort Cables

Unlike HDMI - DisplayPort has only one type of cable, whose current version is 1.2 capable of transmitting video with a maximum resolution of 3840 x 2160 @ 60 Hz and has 3D support. In terms of sound transmission, it is a little more complicated here: the cable can transmit multichannel sound, but it cannot return the audio signal and transfer Ethernet data.

Pleases support DisplayPort, 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 the 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: is capable of multiplying the signal and transmitting a 2560 x 1600 picture already at 22 meters, and if it is made of optical fiber (not copper), then the image can be "delivered" to 100 meters and further.

Number of tracks of audio and video content

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

Each DisplayPort is capable of simultaneous output to 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 have come to the most interesting part: let's analyze which is better - HDMI or DisplayPort.

HDMI was designed 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 cannot do, for example, audio return over the same cable (ARC).

DisplayPort, more, was developed for computer technology, 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 very good. HDMI got more distribution and widespread use... Perhaps, in the future, manufacturers will take into account the need to complete their devices with several interfaces, which will give more "flexibility" to the average user.
