What cables are needed to connect the monitor

HDMI specifications

Let’s continue to analyze which is better, DVI or HDMI. The latter has smaller dimensions and 3 form factors. This is the standard connector for connecting monitors and TVs to a computer. But the other two, namely mini and micro, are much smaller and are used to connect mobile devices that do not have enough space to install a full-fledged HDMI.

cables, needed, connect, monitor

There are several HDMI revisions and the connector itself is constantly evolving. In this, both types are similar. This complicates the answer to the question of which is better, DVI or HDMI.

The latest versions can support resolutions up to 10K, and the frame refresh rate is 60 Hertz. But with 3D images it works at a frequency of 120 Hertz.

It should be noted that an HDMI cable carries audio in 8-channel mode, which eliminates the need for additional wires. This is especially useful for TVs with built-in speakers. Supports AMD FreeSync for gamers. Let’s add that the maximum cable length is longer than that of DVI. Models up to 30 meters long are on sale.

DVI vs HDMI: which is better for a monitor, features and specifications

Manufacturers often bundle video cards, TVs and monitors with several different connectors. Most often you can find HDMI and DVI. Of course, other connectors are also found, but not always both devices are equipped with them. For example, analog VGA is outdated and video card manufacturers no longer use it, which automatically removes the question of application. Consider the most common connectors and analyze which is better, DVI or HDMI.

DVI specifications

DVI connectors are among the most popular and commonly found. Despite the fact that it was developed a long time ago, the connector owes its popularity to the development of modern technologies. So, this kind of connector boasts high frame rate operation, unlike other inputs.

Before answering the question, which is better. DVI or HDMI, consider what the former is. Note that there are several types of DVI. Each has its own characteristics, so they are not always compatible with each other. For this reason, you need to know exactly which DVI is used in your device.

How DVI and HDMI are similar

To decide which is best for a monitor, DVI or HDMI, consider their common features:

  • Both connectors are common enough.
  • Both are modern and evolving.
  • Capable of transmitting high quality digital signal in high definition.
  • Supports the transmission of 3D images with a refresh rate of 120 Hertz.
  • Signal quality is indistinguishable.
  • Due to the use of one digital data transmission technology, both connectors are compatible with each other, only an adapter is needed.

This list is for comparison HDMI with DVI-D dual link connector, as other versions are noticeably inferior and are not able to compete on equal terms.

Which connector is better, DVI or HDMI?

Both connectors have a lot in common. The merits make them desirable for connecting a monitor, TV or projector to a computer. And the differences are not flaws, but rather the features of a particular system. However, based on the latter, it is possible to identify areas for which each connector is better suited.

Which is better, a monitor over DVI or HDMI? The answer will depend on which goals prevail for the user. Monitor specifications are also taken into account.

So, if this is a regular model with FullHD resolution (the most common option), there will be no difference between the connectors. The same situation is in the case when the monitor is capable of reproducing in 3D format. Even at 2K resolution, both connectors will show the same result.

DVI types

  • DVI-A. perhaps the simplest and oldest option. The letter A here means that this connector is for analog signal only. In fact, this is an analogue of the outdated VGA.
  • DVI-I single link. This option combines two signals at once, analog and digital. Which one will be used depends on the device and type of connection. Note that this option is fully compatible with VGA, although a small adapter is required.
  • DVI-I dual link. It differs from the previous one in that it is capable of transmitting an analog signal and two digital signals at once. This allows you to increase the maximum allowable resolution.
  • DVI-D single link. This variant is equipped with only one digital channel, which limits its capabilities. So, it is capable of transmitting only images with a resolution of up to FullHD, and the maximum frequency is only 60 Hertz. Login can be considered obsolete.
  • DVI-D dual link. This is the most advanced and modern type of this connector. It has two digital channels at once, which allows you to work with a maximum resolution of 2K. The connector is perfectly compatible with monitors with a refresh rate of 144 Hertz. Supports 3D image. There is also support for Nvidia’s G-sync feature, which gamers will especially appreciate.

Not all formats are compatible with each other, and this should be taken into account. The connector itself is quite large, which is why it is equipped with an additional mount. Note that the cable length is limited and usually does not exceed 10 meters.


The difference between the two connectors will help answer the question of how best to connect a monitor, DVI or HDMI:

  • HDMI version 1.4 allows you to transmit images at a maximum resolution of 10K, which is not the case with DVI-D, which is capable of transmitting images in 2K resolution.
  • HDMI has a refresh rate of 60 Hertz. In other words, this is the number of frames that it can output. DVI-D, on the other hand, is capable of supporting a much higher refresh rate.
  • The HDMI connector is equipped with an audio channel to reduce the amount of wiring required when connecting to a TV. And in version 1.4 Ethernet is still present. Thus, using only one cable, you will transfer the image, sound and connect the TV to the Internet.
  • HDMI must be equipped with HDCP. This is protection against illegal copying. It determines whether you can watch pirated films on a licensed Blue-Ray player.
  • HDMI cable is much longer than DVI.

Similarities are also reported for HDMI and DVI-D with two digital channels

About the interface

The abbreviation HDMI stands for High Definition Multimedia Interface, which means “interface for high definition multimedia”. This standard is used to transmit digital signal in high (uncompressed) resolution and multi-channel audio signal with copy protection. Actually, the scope of application is the answer to the question of what HDMI is needed for. to connect one device (signal source) to another (receiver and translator), and this is clearly demonstrated by the illustration below.

Let’s give a brief analogy: if we discard the appearance of connectors and cables for connection, the interface we are considering is inherently a qualitatively improved version of the previous DVI standard used to connect a monitor to a computer. An important difference between the first and the second is that it supports not only video data, but also audio. Below, in the paragraph “What is different”, is a link to our material, where HDMI and DVI are compared.

What are the types

In addition to the fact that HDMI as a standard is used in different areas, more precisely, on different equipment and technology, cables (and therefore connectors) used for direct connection are of four types. Their main differences lie in the speed of data transfer, and sometimes in functionality. We talked about all this in detail, as well as about the existing form factors, on our website in one of the previous materials.

Where is used

Obviously, since HDMI is designed to transmit video and audio signals, then it is also used in multimedia and computer technology. This includes PCs (more precisely, graphic adapters and monitors), laptops, televisions, TV-set-top boxes, game consoles, players (home theaters, stereos, radio tape recorders (including in cars), receivers, etc.). projectors, and some smartphones and tablets. On our website you can find separate materials on connecting different devices via HDMI cable, links to some of them are presented below.

How to choose

Of course, knowledge about what an HDMI cable is, where it is used and what types it is, is enough only in theory. Much more important is practice, namely, choosing the right cable to “bundle” specific devices with each other, be it a TV and a console or a multimedia set-top box, a computer and a monitor, or something else. We have already answered all the questions that an ordinary user may have before making a purchase in a separate article.

What is the difference

So, we have designated all the features of HDMI, including both the connectors themselves and the cables corresponding to them. The last thing I would like to draw your attention to is the difference between this interface and other related standards used primarily in computers and laptops to connect a monitor. For each of them on our website there are separate materials, with which and

What is an HDMI cable for?

Almost any modern technology focused on working with video and audio is endowed with an HDMI connector. To connect, in this case, you cannot do without an appropriate cable. We will tell you about what he is and why he is needed at all in our today’s article.

In this short article, we tried to briefly talk about what an HDMI cable is for, what it is and where it is used. You can learn more about each of the varieties, selection issues and comparison with similarly intended interfaces from individual materials on our website, the links to which we have provided above.

Popular questions about connection and cable selection

We figured out the features of the interfaces, now let’s talk about which one to choose from. Typically, a computer or laptop has multiple outputs, while a screen has multiple inputs and a monitor power cable. Which cable is better and more reliable? Do you need a monitor adapter? The following sections will address these and other issues.

What are the cables for connection

Connection interfaces are divided into two types. analog and digital. The first transmit a signal by changing the voltage on each channel of the cable, which is responsible for one or another parameter. Appeared in use when CRT monitors were in use. Now, when LCD displays are on sale all the time, analog interfaces are being replaced by the second type. The digital interface uses binary code to transmit data and is therefore ideal for new monitors and computers. However, the analog ones are still not out of use.

The following are the types of interfaces commonly encountered in modern technology:

  • VGA;
  • DVI;
  • HDMI (and its variations);
  • DisplayPort;
  • Thunderbolt.

The monitor and the computer have the same interface. HDMI or DisplayPort?

Which interface to choose? When there is a choice between analog and digital data transmission methods, it is logical that you should opt for the latter. But HDMI and DisplayPort, at first glance, are very similar to each other. Which one is better to stop at??

So, using DisplayPort is advisable if:

  • You have multiple monitors with this interface;
  • You have a high-resolution monitor;
  • There is one monitor, but HDMI connectors are needed for other equipment.

In all other cases, feel free to use HDMI. this will be the best choice.!

What if I take different versions of the HDMI connector?

Problems can only arise if you want to connect a Mini or Micro HDMI cable to a standard connector. In this case, you will need to use an adapter (this is not an adapter, and therefore it is inexpensive).

If we are talking about different versions of the HDMI interface. for example, 1.3 and 1.4, then the devices can be safely connected. It is just that the data transfer will take place according to the older version. In our case, it will be 1.3.

The devices have different interfaces. For example on laptop HDMI on VGA monitor

A common problem is when device connectors do not match. However, there is no need to worry. computer engineers have found a solution. Although HDMI and VGA use fundamentally different methods of transferring data, you can find converters on the market that do not take up much space and convert one type of signal to another. Thus, by combining the SVGA cable and the HDMI adapter, it is possible to continue using the monitor, forgetting about such an annoying discrepancy.

Monitor cable

Connecting a monitor to a computer is a very effortless process. The screen is connected to the system unit with a cable, and everything works. But questions about the choice of cable are already emerging. Typically, a monitor has several inputs with different connectors. Which one should you choose? The article is intended to provide an answer to this question.

Monitor connectors for connecting to a computer

The names listed above are the names of the technologies that include the monitor cable, jack, etc. Therefore, it is logical that the connectors in the monitors are named according to the interfaces used. The following subheadings will briefly discuss these computer connectors and their features.


This digital interface is predominantly used for high-resolution displays because it has a high data transfer rate (up to 21.6 Gbps on a wire up to 3 meters) and also has audio signal transmission capabilities. Like HDMI, it uses signal encryption, but using its own technology. The resolution supported by the interface is up to 3840×2400.

Projector to computer

The need to use a projector is found in various institutions. But often the connectors on the devices do not match. In this case, a converter is required as most projectors display an analog image.

Adapter selection

Modern video cards have digital inputs, but they can be connected to analog monitors. For this, an active adapter is used. The device helps to convert digital image to analog.

Before buying a converter, you must:

When choosing, keep in mind that cable size affects image quality, reducing the latter with increasing length. Most digital interfaces carry not only video but also audio. Thanks to this, they can be connected to speakers or a TV, but you need a special adapter model. Converters do not require configuration: just connect and start using.

HDMI adapter. VGA

The simplest device, model HD1161, allows you to display an image on a monitor. It is a wire with HDMI output, while VGA can be both output and input. Does not output sound, but has a low cost. Has a length of 15-20 cm, which is increased by a 2 HDMI wire of the required length.

Model HD1160. Similar to a simple adapter, but also provides sound with a 3.5 jack. Has four cables: HDMI for connection to the source. graphics card, VGA for monitor connection, jack for audio transmission and USB for charging. The latter is plugged into an available video card slot, if possible, otherwise. to any free admission. If the graphics card has high power, HDMI power is allowed.

The converter has three inputs. mom, and USB. dad. To extend the length, use a 2 HDMI cable. The device supports FullHD resolution with a refresh rate of up to 60 Hz.

HDMI adapter. VGA with YPbPr S / PDIF RCA

This is a transducer, model HD1181. powered by the electrical network. Contains four outputs. Supports one of two sources connected at the same time. by VGA and YPbPr. To switch between the latter, there is a key on the main panel of the device.

Sound is transmitted via optical cable or RCA. S / PDIF output allows you to connect the device to RCA interface with one input and transfer video and audio signal.

Permitted resolution. 1920×1080 VGA or 1080p YPbPr. Allowable refresh rate of the screen. 50 or 60 Hz respectively. The converter is used as an adapter or splitter of an analog signal.

Studio equipment to computer

Studio equipment refers to cameras used to capture images. Converters are used when writing to a device connected to a computer with a wire. This is found in cinematography and professional photography studios. The image is immediately sent to the processing program, where special effects specialists and editors process the video sequence, and photographers apply various filters.

Reasons for connecting through an adapter

Many users change parts of a PC one at a time, first purchasing a computer, then a peripheral. There is no VGA connector on modern video cards from leading manufacturers. HDMI and DVI only. On the other hand, older monitors only have a VGA output.

In such a situation, the problem arises of connecting devices to each other. To solve it, you need an adapter. Please note that VGA. analog connector, and HDMI and DVI. digital. An active adapter is used to connect RX 400 or GeForce 1000 and higher video cards. signal converter.

How to connect

Regardless of which technique is connected, the connection is not difficult. To connect a VGA monitor to HDMI, the connectors are connected to the corresponding interfaces, if necessary connecting with an additional adapter.

To provide sound, use a converter with jack or RCA, connecting them to the appropriate connectors. It is necessary to take into account the colors of the so-called tulip.

Adapter advantages

The converter is designed to connect devices with VGA output to computers with HDMI or DVI input. Adapters. the only way to create a workable system without the clutter of wires or buying a new monitor. In addition, with their help, you can connect not only a computer to a monitor, but also a TV or studio equipment with a screen.

How to connect a monitor to a computer

Each user must be able to correctly connect the monitor (and other components) to the computer system unit (PC, PC). The need for this arises when buying a new monitor (display) instead of the old one, and with elementary cleaning or rearrangement of the workplace. To better understand the components of a computer, we suggest reading an article about how a computer works. For connection on the system unit there are connectors with holes for connecting cables from the display. The terminal connectors of such cables have pins instead of holes for mating with them. (These two constructive types of connectors in everyday technical speech are often called “dad” and “mom”).

Interfaces designated by the same letters should be distinguished from connectors. Strictly speaking, connectors are nothing more than switches. Interfaces are a broader concept. They have different technical characteristics. The same interface can be switched using different connectors.

DisplayPort Monitor Connection

Modern monitors and video cards are equipped with a DisplayPort (DP) connector to implement the most advanced interface of the same name to date.

The DisplayPort interface is available in four versions, designated 1.2, 1.3, 1.4, and 2.0. Their main technical characteristics are presented below in the same sequence.

  • Bandwidth in Gbps. 21.6, 32.4, 32.4 and 80.
  • Screen resolution at frame rate in fps. 38402160, 51202880, 51202880 and 10240 × 4320.
  • Frequency in kHz and the number of audio channels. 768/8, 768/8, 1536/32 and 1536/32.

Types of computer connectors and interfaces

On a modern system unit, there are the following specialized connectors for communication with the display:

  • VCA;
  • DVI;
  • HDMI;
  • Display Port.

Connection can also be made via a universal USB 3.1 Type C connector.

The video card (video adapter) connectors for connection with the monitor are located on the back of the system unit. Their position depends on the type of video card installed in the computer. As you know, it can be built into the system (motherboard) board or stand-alone (discrete). If it is discrete, then the corresponding connectors for inserting the cable from the monitor into them should be found in the lower part of the rear wall of the system unit. In the case of a video card integrated into the motherboard, its connectors are located at the top.

Connecting a monitor via DVI

All other communication interfaces between the monitor and the computer are digital. Information transmission is based on discrete electrical signals in the form of a sequence of ones (there is a signal) and zeros (there is no signal). They are much better protected from interference. Relatively recently, Russians could be convinced of this when they switched to digital television.

There are several types of DVI connector.

DVI-A only supports analog data transmission. The other two are digital. Additional DVI-D pins make it HDMI compatible. And the DVI-I version is also compatible with the outdated VGA connector. Both of these varieties are available in Single Link and Dual Link variants, which differ in the maximum screen resolution. For Single-link it reaches 19201600, and for Dual-link. up to 25601600. DVI bandwidth. up to 3.4 Gbps. To maintain picture quality, the cable length should not exceed 10 meters.

Configuring display settings

The preferred way of setting is software, through the Windows 10 settings window. It does not depend on the video card used.

  • We click the “Start” button, then the gear sign (item “Parameters”). Read more in the article about the Start menu.
  • In the “Parameters” window, click the “System” section.

The first (top) configurable parameter is “Night Light”. If the user regularly works at the computer in the dark, then he can activate an ergonomic parameter that allows you to give the colors of the screen a “warm” shade. Adjustable “Night light parameters” are presented in the window of the same name.

The following. “Windows HD Color Setting”, are activated only on a suitable display.

The following settings are much more in demand. scale, resolution and screen orientation (see screenshot above).

Connecting a monitor via USB 3.1 Type C

The newest universal USB Type-C interface with excellent technical characteristics has three modes of operation. standard, alternate mode and Thunderbolt 3. Standard mode is not suitable for transferring images to the Monitor. But this can be done in two other modes.

USB Type-C Alt Mode is DisplayPort and HDMI compatible. True, the connected source must support the alternate mode of the USB Type-C interface. Another limitation is that the cable length should not exceed a meter.

The use of USB Type-C to connect a monitor to a computer has good prospects in the current trend towards universalization.

Wireless connection

The evolution of computer technology leads to an increase in the specific weight of wireless equipment. It is implemented using three technologies. Bluetooth, Wi-Fi and infrared connection.

Wireless monitors also exist, but the picture quality on their screen is quite often poor. The fact is that most video cards cannot fully transmit the generated video signal over a wireless channel. Dell 23 S2317HWi is one of the few wireless monitors that can display a high-quality picture. It uses built-in Wi-Fi.

Types of cables for connecting a monitor and what they are?

Good day, friends! A wireless monitor is a convenient thing, but a pleasure for most gamers is still expensive.

I draw your attention to the fact that this is so far: when the first LCD monitors appeared on the market, not everyone could afford them and the majority continued to buy pot-bellied CRTs, but after a dozen years the situation changed dramatically.

Today, everything is exactly the opposite: almost everyone uses liquid crystal displays, and cathode-ray tubes have gradually “died out”, as they are almost never produced or used.

For this reason, most users in the old fashioned way use wires in order to connect the monitor to the system unit.

In this post, let’s look at what kind of monitor cables there are, which is better to use depending on the features of the device’s operation and how long the wire should be so that there is no signal loss and, as a result, picture distortion.

The oldest format, which was developed in 1989 by IBM for the PS / 2 series computers. It is logical that the corresponding cables appeared along with the slots on the video card. In older CRT displays, one end of such a cable can be soldered tightly to the board inside.

However, almost all modern flat-panel monitors are equipped only with slots where you can connect the corresponding cable. Sometimes you have to buy it separately: for example, the basic package contains only VGA, but you have to pay extra for HDMI.

A modern lace of this format is equipped at both ends with plugs with special locks that screw into suitable connectors on a video card or monitor.

Typically, the tips are marked in blue. The higher the maximum resolution of the transmitted image, the shorter the permissible length of any wire connected to the computer (not only VGA). In this case, with a resolution of 1600×1200, the length of the wire should preferably not exceed 10 meters.

It can transmit both digital and analog images. There are several types of DVI ports, each of which must use the correct cable. They are equipped with incompatible keys, so you will not be able to connect an unsuitable cable to the slot.

When transmitting an image with a resolution of 1920×1200, the length of the cable should not exceed 10 meters, and the length of an active one, equipped with a signal amplifier, should not exceed 61 meters. The connectors of such a cable resemble VGA and are fixed in a similar way, however, they are usually marked in white or yellow.

Suitable not only for PC and monitor, but in general for any video equipment: home theater, projector and the like. In addition to the image, it can also transmit sound. There are three types of incompatible connectors of different sizes, which are usually not color coded. regular, mini and micro. Retainers are not provided.

The maximum length of a simple cable is 10 meters, and equipped with a signal amplifier and ferrite filters, up to 35–40 meters. As in the previous case, such a lace is convenient to use in public places: for example, a sports bar to connect a monitor or a conference room when giving a presentation.

Display Port

Not suitable for connecting a budget video card, as they are usually not equipped with such connectors.

Expensive gaming models are able to produce maximum results using such a cable, including due to the possibility of activating AMD Freesync and Nvidia G-sync technologies (for more details, see the publication “What makes a gaming monitor different from a regular one”).

Today there is only one type of such connector, which is also not color coded. The maximum wire length should preferably not exceed 15 meters. Signal amplification, alas, is not provided for by the design.

Adapters and adapters

If the connectors on your monitor do not match the slots on the video card, you can always find an easy way out in terms of cost. For example, there are adapters and adapters VGA-DVI, VGA-HDMI DVI-HDMI, and for any type of connectors.

The problem is to “make friends” a display with an incompatible port, so you should not buy an adapter, but an adapter, the cost of which is usually only a couple of dollars higher.

I recommend keeping a reference point and using HDMI cables as the most popular and convenient option. Not every monitor or graphics accelerator can boast of the Display Port, which is more advanced in technical terms.

HDMI is provided by the design of any modern device.

I also advise you to read about the pros and cons of a curved monitor. it turned out to be a very interesting article.) And if you have 3 minutes of time, you can enlighten yourself about which brand of matrices is better.

I would be grateful to everyone who shares this publication on social networks. I hope the information was useful to you. Thank you for attention. Till tomorrow!
