How long is the hdmi cable? The principle of data transmission via HDMI. Which is better: HDMI, DVI or VGA

Modern TVs have an innovative interface and a wide range of features. They, like computers, are digital devices, so they have many connectors on the back. Many buyers, when they come to the store to make a purchase, are faced with the question - what is HDMI on TVs and what is it for? It's simple. This connector is used to transmit high quality images.

Nowadays it is almost impossible to find equipment on store shelves that is not equipped with an output for an HDMI cable. It is present on the casing of players, multifunctional multimedia centers, various game consoles, personal computers and video players. It is used to transmit the highest quality (HD) video, audio and photos.

Modern plasma and LCD TVs have many outputs, to which several devices can be connected simultaneously. This interface is a great space saver because one cable can transmit audio and video in different directions. As a result, the user can use one cord instead of 5-6 others.

The cable supports high quality signal. For example, video is transmitted with a resolution of up to 1080 p, and audio is transmitted with up to eight audio channels at a frequency of 192 kHz. These parameters meet the highest standards in the field of quality multimedia content.

Want to know what HDMI is on TVs? This data transfer protocol was first developed in 2002, after which it became widespread in equipping household appliances. It has the following characteristics:

High throughput (up to 18 Gbit/s);
Long cable length (standard up to 10 m, and extended size up to 35 m);
Ability to support CEC and AV.link protocols;
DVI compatible. There are special adapters that allow you to connect other devices to the equipment.

Also, any master can install special rings on the cable at the very beginning and end of the cord. They provide high immunity to interference. To increase the signal range, video senders, as well as amplifiers - repeaters and equalizers, can be used in combination with them.

Before purchasing, always check to see if your TV has an HDMI input on the back. What is it for, you ask? It transmits a high-quality digital signal - high-definition video and multi-channel audio. At the same time, all data in the interface is protected from copying. This protocol is an alternative to analog connection types - SCART (Euro-AV) or RCA (standard AV).

Specifics of the device and varieties

There are the following types of interfaces containing 19 contacts:

Standard (Type A);
Mini (Type B);
Micro (Type C).

However, the cable has an unusual design. On the outside it is covered with a special shell that protects it from mechanical stress. The next layers are a shielding braid made of copper wire for soldering, an aluminum screen and a polypropylene sheath. Inside the cord there are communication cables (twisted pair type) and separate conductors for power and other signals.

Allows you to turn the device into a multimedia station with an HDMI input on an LCD TV. What is this multi-function connector used for? It allows the user to control all devices from one remote control, and in the near future - from a personal computer.

Thanks to the HDMI interface, we can transmit uncompressed audio and video signals digitally. The transmission method using digital wire appeared on the market almost 15 years ago. What does an HDMI cable look like?

Many cables on sale look similar, and customers don't focus on their specifications when choosing a cable for their home theater, console or receiver. Does it matter how we choose cable? Undoubtedly!

This article will tell you which digital cable to choose for individual devices, but first let’s find out what an HDMI cable is, how transmission through this interface works, why you should buy an HDMI cable, what it is used for and what parameters such a cable should have.

HDMI cable and interface

HDMI is an abbreviation for High-Definition Multimedia Interface, which in English means high-definition multimedia interface. The presentation of this standard took place in 2003. A lot has changed since then, and several remakes have already appeared on the market. Each of them offered increasingly faster data transfer than its predecessor.

As already mentioned, this standard is used to send uncompressed multi-channel audio and video data. The digital cord is ideal for connecting digital devices. Thanks to a single standard, most television devices such as Blu-Ray players or even DVD players, TVs, game consoles, set-top boxes, set-top boxes or monitors can be combined. There are a lot of configuration options.

Starting with version 1.4, HDMI technology supports scan resolutions exceeding 1080p, including Deep Color technology and 3D formats. The HDMI High Speed cable has been designed to deliver 1080p and higher resolutions, including new imaging technologies such as 3D, 4K and Deep Color.

HDMI cable classification

In fact, the HDMI standard is a complete mess. Of course, everything is described in great detail in the standards tables, which is true, in fact we have many modifications of the HDMI standard, and they all relate to a connector that looks identical in each version. It's no surprise that electronics retailers are trying to exploit this confusion and push us into buying expensive but unnecessary cords.

HDMI technology has four main cable versions:

standard – for 1080i scanning;
high-speed – for 4K/60 Hz;
premium – for 4K/60 Hz, but with full color resolution 4:4:4, that is, without so-called subsampling;
ultra-high-speed – for 10K using the connector in version 2.1.

Speaking of connectors, from the point of view of the intensity of the supported signal, we can also distinguish four main options:

in version 1.0-1.2a the approximate throughput is up to 5 Gbit/s;
version 1.3-1.4b provides up to 10 Gbit/s;
version 2.0-2.0b – up to 18 Gbit/s;
version 2.1 – up to 48 Gbit/s.

The latest version of the HDMI standard, 2.1, was announced on November 28, 2017. The HDMI 2.1 cable supports a maximum data transfer rate of 42.6 Gbps, and can also support Display Stream Compression (DSC) to deliver 7680 x 4320 resolution images at 120 Hz.

HDMI technology implies a high quality plug-in connection. The HDMI cable may have different connectors. The classic digital cable has two plugs (“male”). On sale you may find wires with a socket contact (“female”) on one side and a plug (“male”) on the other side as an extension cord. There are also angled or rotatable ends, which will be useful, for example, when you hang a TV on the wall.

Continuous progress and miniaturization are encouraging manufacturers to equip equipment with smaller and smaller connectors, while their throughput increases. The microHDMI and miniHDMI standard is intended for connectors on portable devices.

Connecting a TV to a computer is not a problem at the moment. Just make sure your computer and TV have HDMI jacks. Every HDTV has at least one or two HDMI connectors. Laptops often have HDMI, while ultrabooks or other models offer microHDMI. If your computer has microHDMI installed, you will need to purchase an adapter or microHDMI to HDMI cable with the adapter.

First of all, you must decide what the HDMI cable is for, i.e. what maximum permissions will be sent via it.

Buying an HDMI cable for your TV at, choose a cable made in the High Speed HDMI Cable standard, version 1.3 or 1.4, up to 15 meters long. High-speed transmission is especially useful when watching movies in Full HD mode.

D A lower cord is suitable for the monitor. Of course, by choosing High Speed wire, you will eliminate bottlenecks that lead to slow transmission of information. But in most cases, standard wire should do the trick. There is also a length limitation here - no more than 15 m, and the optimal length is 3-5 meters. It is advisable to choose a digital cable 1.3+, with support for Deep Color, as well as a bandwidth of 340 MHz.

For PlayStation 4, as in the case of TVs, you need a High Speed cable with Ethernet or simply High Speed. When playing on PlayStation 4, it is recommended to use faster transmission. By choosing version 1.4+, you will be able to enjoy Dolby True HD support, an audio return channel, 340 MHz bandwidth, a maximum bit rate of 10.20 Gbps, and audio and video synchronization.

Before choosing an HDMI cable for connecting digital gadgets, you should check the quality of the materials from which it is made:

copper-aluminum - inexpensive, but more susceptible to cracks;
copper-steel - durable, but less flexible;
Oxygen-free copper is the most commonly used material in the production of digital cords, characterized by high conductivity and absence of signal attenuation problems, supporting all the functions offered by the HDMI standard.

Expensive or cheap

Cheap and expensive digital cables are no different in terms of picture and sound quality. Fancy cables from famous brands will not provide improved contrast or saturation of the picture; rather, they will guarantee the absence of problems. Moreover, expensive cables, due to the use of various creative shielding methods, become rigid, difficult to bend and hide from view.

You may encounter digital cords labeled Premium. Does this mean they are somehow better? Partially yes. Premium is a paid certificate issued to the manufacturer. This marking tells us that this wire can operate up to 18 Gbit/s and can cope with the 2.0 standard. But products without this badge of honor also support the specified transmission speed, so there is no need to specifically “chase” for it, but you just need to carefully study the inscriptions on the packaging.

The best idea when choosing an HDMI cable is to buy a regular, simple digital cable, and in case of problems that most likely will not arise, advertise it.

How to check the functionality of a digital cable when purchasing? Follow the instructions:

check the wire with a cable tester, it can be ordered in the online store;
inspect the soldering of the connector for any mechanical defects; the color of the metal of the plug should not be different;
inspect the cord along its entire length - no protrusions or irregularities are allowed;
study the packaging, it must contain information about the manufacturer and be in a marketable form.

What should an HDMI cable be like?

You already know that the quality of a cable for digital technology does not match the quality of the picture, although the cheapest copies may simply be faulty. We've also determined that the Premium designation is more of a formal price for a defect-free guarantee rather than a criterion that affects the quality of what's connected to our TV. Does this mean that you can take the first cable you see off the shelf and head to the checkout?

Not really. Those who buy a cable only to watch TV and movies in Full HD can do the same. However, it's time to prepare for the UHD standard, that is, 4K resolution with HDR. You may already have such a TV, or you will.

HDR (High Dynamic Range) - high dynamic range

Good cables should have high transmission capacity and maximum resolution at a screen refresh rate of 60 Hz - at least 18 Gbps and 4K with HDR, respectively. Slower cables will stream at 24Hz and provide 4K resolution, but without HDR.

Maximum length

The length of the wire is one of the main parameters taken into account when making its purchase. Therefore, the route and length of the cord should be thought out in advance.

The maximum permissible length of an HDMI cable cannot exceed 15 meters - this is the recommendation of the HDMI Working Group consortium (with the participation of Hitachi, Panasonic, Philips, Sony, Thomson, Toshiba), which oversees the standard. If your telecommunications infrastructure requires the use of a longer wire, then you will have to resort to so-called signal repeaters or signal regenerators. However, in most cases this problem will not affect you, since devices are rarely more than 2-5 meters away from each other. As an exception, we can only assume a projector placed on the ceiling or at the other end of the room.

Numerous tests have shown that a working digital cord, made of the simplest basic materials, up to 1.5 m long, copes well with transmission. The quality of transmission can only be noticed on fairly long wires and large TV screens, for example, when you need to be able to transmit images using 3D technology or 4K HDR (a new standard that is becoming increasingly popular among gamers) using this wire.

If you still don't know how to choose an HDMI cable that is reliable, does not attenuate the signal and supports all the important functions of a modern TV, we will try to help you. We suggest using several important characteristics as selection criteria: cost, version of the standard, dimensions, connector shape.

Price

No matter how hard marketers try to highlight the special qualities of expensive HDMI cables (more than $100), which include gold and silver elements, practice has shown that they are practically no different from their budget $5 counterparts in their ability to transmit video signals and multi-channel audio without loss.

If you are not going to constantly disconnect and reconnect the HDMI cable to the connectors of your TV and peripheral device, then purchasing its inexpensive version will be quite justified. This axiom is valid for short HDMI cables (up to 10 meters).

HDMI cable version

Since the approval of the HDMI standard in 2002, the following versions have been developed: 1.0, 1.1, 1.2, 1.2a, 1.3, 1.3b, 1.4a, 1.4b, 2.0. Today, most modern multimedia equipment supports HDMI 1.4, although there are quite a lot of cables of the old 1.3 standard on sale.

The most modern version of HDMI 2.0, which provides ultra-high resolution three-dimensional image transmission at an increased frame rate (50/60 Hz), is used only in top models of electronic equipment. For the average user who wants to watch 3D programs and UltraHD videos in acceptable quality (at a frame rate of 25/30 Hz), it will be enough to stick with an HDMI cable version 1.4.

Some HDMI cables contain the word Ethernet in their markings, which means that they additionally contain a twisted pair cable that allows you to directly connect to the Internet. The point is controversial, considering that most modern TVs already support Smart technologies, which involve wireless and wired web switching methods.

HDMI Cable Dimensions

When choosing an HDMI cable, you should follow a simple rule: the longer you need the cable, the thicker it should be. In this case, manufacturers use thicker conductors and a good layer of insulation, which do not weaken the signal and provide increased reliability of the cable itself.

For example, experts say that if an HDMI cable is about 5 meters long, its thickness should not be less than 7 mm. But a 20-meter cable should not be narrower than 11 mm. Sometimes the marking of an HDMI cable is indicated not in the usual metric system, but in the American AWG caliber. In this case, remember: the lower the specified AWG, the thicker the HDMI cable will be.

Connector shape

Well, the last parameter that determines which HDMI cable to choose is the shape of the connector. Today, 4 types of HDMI connectors are most common:

Standard or full-size HDMI (Type A Full Size) – for most modern home equipment;
Mini-HDMI (Type C Mini) – for smartphones, tablets, portable video players and digital video cameras;
Micro-HDMI (Type D Micro) – for digital video cameras and miniature devices, such as video cards;
Car HDMI (Type E) – has a more secure mount.

Therefore, before going to the store, it is advisable to look at the technical documentation of the equipment that you want to connect with a cable to find out what type of HDMI connector it uses.

If the materials in this article did not help you solve your question, ask it on our forum.

Hello, friends.

From this article you will receive basic useful information about HDMI, what it is, where and why it is used, what characteristics it has and what types there are. Why should you know this?

Nowadays, most multimedia equipment is connected through this interface, and it is possible that you also use it, perhaps without knowing it. Also, after reading the article, you will be able to correctly select cables for connecting devices.

Introducing HDMI

This abbreviation means the phrase “High Definition Multimedia Interface”, which exactly translates as a high-definition multimedia interface. It sends high-resolution digital video signals as well as copy-protected multi-channel digital audio.

Simply put, it is a channel for transmitting digital images and sound from one high-definition device to another. This process is carried out using appropriate cables. They can connect video cards and monitors, home theaters/game consoles and modern TVs, tablets/phones and computers, etc.

By the way, the connectors for the above gadgets differ in form factor (size): large equipment is usually connected, mini-HDMI - smartphones and some tablet models, micro-HDMI - laptops, tablet PCs, etc. equipment. Each port contains approximately 19 pins.

Characteristics

Let's look at the main features that distinguish this interface from others:

Data transfer speeds range from 4.9 to 48 (new for 2017) Gbit/s.
Capable of transmitting uncompressed high-definition video, 3D TV signals, and 8 channels of digital audio.
Displays high-quality images on screens with an aspect ratio of 16:9, a resolution of 1920×1080 pixels and higher. So that you can compare: TVs that were outdated by today’s standards had the corresponding parameters of 4:3 and 704x480 pixels.
The frequency of supported resolutions in modern interfaces varies from 50/60 to 100/120Hz
Supports Ethernet connection at speeds up to 100 Mbit/s.

About cables

Cable cross-section includes:

External covering;
Wire braiding for shielding with the addition of a bare copper core for soldering;
Another shielding layer of aluminum foil;
Sheath made of polypropylene;
Twisted pairs of the 5th category with a resistance of 100 Ohms, which are intended for transmitting information;
Shielding of the specified twisted pairs from external insulation and wire for soldering;
Another twisted pair without shielding, tailored for SDA SCL signals;
Additional conductors for control signals and power.

Length

The standard cable length is 10 meters. But you can extend it to the required size using external or built-in repeater amplifiers. They are not installed at the signal output, but closer to the receiver.

To avoid interference, some manufacturers equip their products with ferrite rings on one side and the other.

And keep in mind that the longer the cable, the more massive the conductor should be.

Types

There are 5 types of HDMI cables:

Standard. Looking for a budget option? Standard - for you. Used to connect not too demanding household appliances (DVD player, satellite receiver, plasma and LCD panels, etc.).

It doesn't have super high-quality work. Judge for yourself: it transmits an image with a resolution of 1080i or 720p, the maximum throughput is 4.9 Gbps, the frequency band (video stream transmission) is 165 megapixels, and the color depth is 24 bits.

High speed. Do you own a Blu-ray/HDD player, widescreen screen or other upgraded equipment, or are you simply a connoisseur of high-quality images? Note "High Speed".

Interacts with any formats, including Deep Color and 3D. It features support for Audio Return Channel technology, which allows you to transmit audio without another cable. Note that receiving devices must also support it. These are usually marked ARC.

It has the following parameters: it works with a resolution of 1080i and higher, the same number of bandwidths (in megapixels), a speed of 10.2 Gbps and a color depth of 48 bits.

Standard with Ethernet. The same as in the first paragraph, only in addition there is an option to connect to the Internet.
High-speed Ethernet. I think it's clear without explanation.

Automotive version (Standard Automotive). A separate type of cable used to connect devices to a car media system.

Difference between HDMI and DVI

The predecessor to HDMI was the . Most likely, you also dealt with it when you connected a monitor to your first computer. But only video was transmitted through this channel. As you can already conclude, the main improvement of the HDMI interface is that it can also transmit sound.

But this is not its only difference from DVI. Another modern port is smaller in size. It also transmits only digital signals, unlike its older brother, which can also handle analog data. The bandwidth of HDMI is also higher than that of DVI (the latter operate at a speed of 3.4 Gbps).

That's all.

I look forward to seeing you more often on my blog.

The IT technology industry does not stand still, but, on the contrary, is developing dynamically. Almost every day new devices appear that make everyday tasks much easier. Particular attention should be paid to the synchronization of television equipment and computer equipment.

To connect a laptop or PC to a TV, the HDMI interface is often used. This TV cable is significantly superior to other available cords, such as VGA or tulips.

Despite the fact that this method of synchronizing a laptop and TV has been used for quite a long time, few people know according to what criteria an HDMI cable is selected. In fact, it is extremely easy to get confused and make mistakes. Especially if you have no idea what meaning is hidden behind this English abbreviation.

High Definition Multimedia Interface or HDMI is a multimedia interface that provides the transmission of the highest quality video content and multi-channel digital audio signals.

Terminology is, of course, good, but let's figure out why HDMI is better than conventional tulips. The fact is that using old interfaces, you will not be able to broadcast images with maximum quality to the TV screen. Therefore, to watch movies in Full HD, you should use HDMI and not any other cable.

If we compare this interface with DVI, it will also be more advantageous. Firstly, it is compact. Secondly, it is equipped with copy protection.

We are convinced of the relevance of the cord, but how to choose it? Let's consider the main criteria:

version;
price;
length;
thickness;
material.

In the future, we will consider these criteria in detail and give specific recommendations for choosing a wire, but now we will analyze the areas of use of the cord.

Where are HDMI cables used?

The purpose of the interface is to transmit high-quality content. Mainly using this cord, but you can also use it to connect a smartphone, tablet and other devices.

Bandwidth capacity – 18 Gbit/sec. This protocol was created in 2002 and began to be actively used. The HDMI cable provides high-quality image transmission and clear sound from your computer to your TV. The interface is unique in that it replaces 5-6 cords at once.

What does the wire look like? In appearance, it is not much different from its analogues. Modern models are available in a fabric shell. Their advantage is that they are better resistant to mechanical damage.

We list the main functionality:

transferring the image to;
clear sound;
copy protection;
displaying pictures on a large screen;
connecting game consoles;
watching films, TV series, TV shows;
playback content from Blu-ray players.

If the laptop is connected to the Internet, then you can watch your favorite movies or TV series online. How does the cable work? Elementary, just connect one end of the wire to the laptop and the other to the TV. Then select the appropriate signal source. After this, the desktop will be displayed on the monitor.

Types and versions

Several well-known companies worked on the creation of the interface: Thomson, Sony, Philips, Hitachi and others. As a result, in 2002 the emergence of a new standard was officially announced. For more than 15 years, HDMI has held a significant position in the digital technology industry. The developers do not stop there, constantly improving the cable.

To determine your HDMI version, check the specifications. Let's briefly look at the distinctive features of all existing versions:

Version 1.0 appeared in 2002. Maximum throughput 4.9 Gbps.
Two years later, modification 1.1 appeared. The developers have managed to improve sound processing for DVD-Audio playback.
In 2005, the interface underwent major changes. Release 1.2 included a wide range of innovations:
- Supports 1-bit audio.
- Using a uniform color space.
- Interaction with low-voltage signal sources has been established.
- The remote control protocol has been added.
1.3 – 2006. The clock frequency has been increased to 340 MHz. The interface began to support deep color, color rendering was improved to the xvYCC standard.
1.4 – added support for playing content in 4K format.
Latest version 2.0. The developers have increased the resolution to 3840x2160 pixels. Supports up to 32 audio channels.

HDMI 2.0 4K 3D UHD CABLE

We've sorted out the versions, this factor needs to be taken into account when choosing a cable. After all, if you buy a cord for playing video in 4K format, but it is the first version, then nothing will come of it.

Now let's talk about the types of HDMI cables, there are also a lot of them. The high-speed cord specification identifies 5 types. Let's look at all the varieties and their specific features.

Standard

Standard View supports 1080i (Full HD) or 720p (HD) video content. Used to connect all kinds of home appliances with minor parameters: DVD, satellite receiver, plasma, LCD and LED screens.

This is a budget option designed for household devices. Suitable for users who are undemanding about high quality picture and sound. Characteristics:

The maximum throughput is 4.9 Gbit/s.
Video transmission frequency – 165 MP.
Color depth – 24 bits.

That's all the average user needs to know.

High Speed

The high-speed type features support for almost all video formats, including 3D and Deep Color. Specifications:

The maximum throughput is 10.2 Gbit/s.
The video stream transmission frequency is 1080 megapixels.
Color depth – 48 bits.

Support for reverse audio channel is implemented, which ensures the transmission of the highest quality audio without the use of additional cords. Naturally, connected devices (home theater or regular TV) must have this technology. Transmits a video signal with a resolution of 4096 x 2160 pixels.

Standard with Ethernet

Standard + Internet is absolutely no different from the first type cable, except that it is equipped with an additional channel for transmitting Internet data at speeds of up to 100 Mbit/s. The function will only be available if the connected device supports Ethernet HDMI technology.

This type of connection makes it possible to establish a high-speed Internet connection and distribute the received data to other devices connected via the HDMI interface. Audio Return Channel support is also implemented.

High Speed with Ethernet

By and large, this is an improved version of the previous type. As for the specifications, they correspond to the parameters of version 1.4. A universal cable that is suitable for receiving and broadcasting content with an Internet connection.

Automotive Standard

A special type that allows you to connect external HDMI devices to car media systems. Experts use this cable when installing an audio system in a car.

HDMI cable connectors

Previously, it was determined that the most progressive type is the High Speed with Ethernet cable in specification 1.4, and now we will talk about modifications to the connectors. Absolutely all types of HDMI are designated in Latin letters. Let's look at popular connectors:

A – standard interface; this is the connector that manufacturers often equip digital equipment with. Suitable for connecting TVs.
C (micro) and D (mini) – reduced HDMI connectors. Used to connect smartphones, cameras, laptops, tablets and other portable devices.
B – the connector has an expanded video channel for broadcasting content with a resolution of more than 1080p. It is less popular than the previously listed types.
E – equipped with a special lock that securely fixes the connector with the port when connecting the device. Used in cars when connecting audio systems.

How to choose the right connector? Consider the connection features, the size of the connector connector, as well as the goal that you set for yourself. For example, Type A is suitable for TVs, and C or D for smartphones.

HDMI cable length and thickness

Surely many users are wondering what length of HDMI cable is best to purchase? According to regulatory documentation, the maximum wire length is 10 meters. There is no such information in the specifications, but often this parameter varies from 75 centimeters to 10 meters.

It is possible that you will be able to find a longer wire. However, it is absolutely not necessary to buy a cord, which is called “with a reserve”. Dimensions that do not comply with regulated standards may later become a catalyst for problems during operation. For example, attenuation or distortion will appear - all this will negatively affect the quality of the broadcast picture.

The quality of transmission depends not only on the size, but also on the material from which the cord is made. For testing, let's take the standard view of version 1.4. These cables are often constructed using 24 AWG oxygen-free copper. As for the High Speed type, it is created from a similar material, but the thickness is 4 AWG greater. This comparison clearly demonstrates that the quality of the material and its thickness directly affect the functionality and service life of the conductor.

It should be emphasized: if a standard cable is made of really high-quality material, then it will provide signal transmission up to 15 meters. If the length of the cord is more than 15 meters, and after connection the loss of picture quality is noticeable with the naked eye, then be sure to use special signal amplifiers.

The high-definition interface must convey absolutely all data to the receiver without any distortion. Many manufacturers note that wires made from expensive metals demonstrate the highest speed of information transfer with the complete absence of interference and failures.

It is worth considering that the use of expensive metals directly affects the cost of the wire. When choosing a cable accordingly, take into account the tasks you set for it. For example, to transfer data from a tuner or satellite receiver, a very ordinary cord will do, since the information flow is not large. Viewing 3D content will require more expensive models.

Expensive or cheap

As noted, the standards are clearly regulated. Therefore, the cable will either provide information transfer or not. Which HDMI cable is better to choose? German gamers conducted an interesting experiment regarding the effect of the cost of the wire on its operation. They purchased many different models from popular and unknown manufacturers.

Video game fans connected to a monitor and displayed the same images. Subsequently, a comparison of screenshots was carried out. For maximum accuracy, checksums were compared. These figures coincided 100%.

It would seem that the cost of choice does not affect the choice of an HDMI cable, but this experiment does not take into account sound transmission at all. Therefore, a repeat experiment was carried out. Again no difference was found. Therefore, there is absolutely no need to overpay for cable.
