For a long time now, the lighting market for home theaters and Ethernet connections has been using a new type of cable called HDMI. This avoids transmitting data entirely to analogue, as was common in older RCA cables. Now it is possible and necessary to transmit information in a completely digitized manner and waste data, video and sound will not be prevented in principle. First of all, select the required type of cable, and then check with them.
Yak right vibrate
- Let us first show respect to the category. If your TV supports low video resolution (up to 1080 pixels), you can select a Category 1 HDMI cable that can transmit data over an internal Ethernet network.
- For HD TVs, you should immediately buy a cable of a different category, which supports a separate 1920x1080 pixels. The truth of the picture will appear high level– the pixels will not be visible.
- Moreover, communion can be different. Considering the American AWG (American Wire Gauge) standard, a 30AWG cable is significantly different from a 24 AWG cable. The first type appears thinner than the remaining richly. For example, 30AWG will be mated in the range of 6-7.3 mm, while 24AWG will be mated in the range of 9-10.5 mm. Naturally, the sooner the cable appears, the more vivid the picture that will be removed will be revealed. Although not as high as buyers might think, the fragments, as has already been said above, are all transferred to a completely digitized view.
- If your computer is connected to a fiber optic line, then to connect it, select a High Speed HDMI cable, which has 19 conductors, 5 of which are connected in pairs of interconnectors, which allows for faster transmission audio and video information ( TMDS).
- I am particularly fortunate to have the opportunity to add the last of the bays. It has already become a standard that the depth does not need to be more than 5 m. If you need a depth of more than 15-20 m, then the buyer needs to be prepared before the brightness of the picture is reduced, The cable will become more sensitive to your support.
The best companies that produce HDMI cables.
This is probably everything you need to know when buying a cable, so you can earnestly respect which HDMI company you choose, and you can quickly find them on the market correct choice I'll help:
- ProLink
Visnovok
The three most popular companies present on our market, ProLink and Belkin, offer carbon dioxide for reasonable prices. I especially buy Belkin up to 5 meters, which is available for most needs, but if you have other needs, you can take a 50-meter cable, but the price will be steep... You can also buy unknown brands, but cables go out of order, that And you don’t know their characteristics, and most often go with the original package or go without it. No more shopping!
Peredmova:
The 4K video format, also called Ultra High Definition (UHD), provides high clarity and vivid color of the image, which is especially important for digital signage systems professional work from video. And, like all innovations, this format has introduced new features that need to be supported.
To transmit a video signal in the 4K format, high bandwidth will be required, up to 10 Gbps. And then new capabilities appear across the entire infrastructure. For the successful implementation of technology in real minds, the entire system may be designed with the following features in mind:
- Lack of permissions
- Vimoga up to frame rate
- Supporting the format with different audio/video interfaces
- New benefits until the cables are exhausted
4K video cameras are required to be taken seriously before testing to ensure that the devices will be suitable for integration into 4K systems, thereby enabling integrators to There is no need to carry out such verifications independently.
Why are you swearing by the 4K format?
Those in the professional audio/video industry will always have to be aware of the remaining developments, and since the 4K format is still not wide enough, a great market is just around the corner.
Technologies are developing, and many manufacturers of displays and media players are already presenting their products with 4K support. This allows for the brightness of the image to be enhanced by large cuts, and given the fact that prices are falling, this technology is becoming even more attractive to the market.
A look at 4K technology
The term "4K" is used to designate video signals with horizontal separation of up to 4,000 pixels (meaning 3840 pixels). In the previous generation, the video signal was assigned a vertical separation (for example, 1080p is a signal with 1080 vertical lines). The difference between the previous 1080p and the new 4K is simply magnificent.
In professional fields, the terms 4K and Ultra HD (UHD) have become practically synonymous, but the important fact is that they are not interchangeable. It is clear that there is a practical difference between them, to be sure. Simply put, 4K is the standard for video production and cinema. UHD is the standard for live displays in the television industry.
Peculiarity of the first. Lack of permissions
All video signals from separate 720p, 1080i and 1080p may, however, be on the same side as 1.78:1 (16:9). Since almost all the displays and signals were used on the same side, everything was simple. For a decade, there was no need to satisfy the daily needs of different parties in a relationship. With the advent of 4K, everything changed, and now there are two standards for the aspect ratio.
The split-frame, commonly called UHD (3840×2160), surpasses the split-frame of 1080p by several times and results in an increase in the number of horizontal and vertical pixels per resolution 1920x1080. In this case, UHD sides are the same as HD video, 16:9. Most 4K displays are available in 3840x2160 sizes.
Other separate productions in 4K format - 4096×2160, from related sides 19:10. It is also called 4K DCI, and is used in the production of films and in cinema systems. Thus, there are displays with separate dimensions of 4096×2160, and more often they are narrowed down - 3840×2160.
A lot of cameras and signals can work with these two permissions. Veterans of the professional audio/video industry may recognize the separate SXGA 1280×1024 format, which may have a non-standard 5:4 aspect ratio, although it does not allow for a 4:3 aspect ratio. This situation even predicts the situation with 4K, if it is necessary to carefully select the display and signal and adjust them to avoid unnecessary stretching and cropping of the image. Expanding the capabilities between current resolutions and 4K will help overcome the challenges of advanced new technology.
Friend's personality. Vimoga up to frame rate
To transmit a video signal from a separate source 1920×1080 and a frequency of 60 frames per second, the required bandwidth is 4.46 Gbps. Thus, increasing the number of pixels by 4 times is also possible to increase the throughput. For example, HDMI supports a maximum throughput of 10.2 Gbps. Therefore, most 4K devices can frame at 30 frames per second or less. Of course, this is not suitable for films, since the output material runs at a frequency of 24 frames per second. It is important to understand what is needed for the video computer programs The frame rate is reduced by half. This results in the need for a system that can process content at 24, 25, 30, 50 and 60 frames per second.
Image encoding technology, known as color subsampling, ensures video transmission in 4K format at a frequency of 60 frames per second, with a data throughput of 9 Gbit/s, with high-quality compression of information up to 4 colors :2:0 – format that is used for Blu-encoding ray. Kolirna Subdisretizatiya is transferred about the jaskravystzhnnya in the publicity of the buildings, and the ilformat about the stabir at the Menchi Zdatatnosti (at the TSOu vipad 1920 × 1080). The human eye is at least sensitive to color, less to brightness, this technology will ensure the absorption of information in at its best with available smoothie throughput.
Particularity third. Supporting the format with different audio/video interfaces
HDMI is not the only way to deliver 4K content. Let's take a look at other interfaces and the frame rates they support.
DVI
The DVI interface is being reviewed in computer environment and in the field of professional audio/video. The DVI standard is based on TMDS technology and comes in two types: single-link and dual-link. Single-link DVI allows you to transmit video from a separate area 1920×1200, dual-link DVI transmits video from a separate area 2560×1600 (2048×2048). Zagalom, single-link is used in 23/24″ displays, for simplicity called Full HD panels. Allow dual-link to create a larger display size, 27″ for 2560×1440, 30″ for 2560×1600, or square displays with separate sections 2048×2048.
Transmission of full separate content 4K - 3840×2160 or more via Dual-Link DVI is possible, but only with a frequency of no more than 30Hz, in connection with limited bandwidth. For a single link, the bandwidth must be up to 4.95 Gbit/s (165 Mhz) and 9.9 Gbit/s (2x 165 Mhz) for a dual link.
HDMI
Essentially, HDMI is the same format as DVI, but it supports a higher pixelation rate, and also allows for greater bandwidth and color depth. This data is included in the HDMI version. Up to version 1.2, HDMI MAVs are similar technical characteristics DVI version 1.3. Moreover, HDMI 1.4 surpasses the characteristics of dual-link DVI, although it is truly a single link. HDMI 1.3/1.4 capacity – 10.2 Gbit/sec (single link 340 Mhz).
As of today, all HDMI 4K displays on the market operate at 30Hz. Version HDMI 2.0, released recently, increased bandwidth to 18 Gbps (600 MHz), successfully competing with DisplayPort, which supports 4K at 60 frames per second. on Narazi There were no displays with components that provide the same functionality. HDMI is becoming the most common standard for almost any common professional audio/video device.
DisplayPort 1.2
DisplayPort is a unique standard. The capacity of the building is approximately 17 Gbit/s, so at the moment DisplayPort is the only interface for full-fledged separate data with full UHD 3840 x 2160 frequency 60 frames per second. DisplayPort is mostly used on graphics cards personal computers. Varto means, everything is daily graphic cards with DisplayPort support new characteristics DisplayPort 1.2, and with a throughput of 5.3 Gbps per bus, and the card connected to it supports more than 30 frames per second.
Thunderbolt
Thunderbolt 1.0 is an interface that is limited to Apple devices. Vikorist is used for a variety of purposes, including video transmission. It is also suitable for DP 1.1 and is used as an output for DisplayPort signals. To support 4K at 60fps, Thunderbolt version 2.0 and DisplayPort 1.2 capacity are required.
Particularity of the fourth. New benefits until the cables are exhausted
However, due to the reduced frame rate and high color subsampling, 4K video transmission requires high bandwidth. And here comes a new benefit for system integrators, maximum dozhina twisted pair (CATx STP) is much smaller, and the cable for HD video transmission is lower.
In analog systems, transmission over long cables resulted in poor picture quality. With digital systems, images may appear faded when transmitting large distances. Moreover, the inconsistency between signal circuits and displays becomes even more problematic when cables are damaged. Just because certain devices have been tested with the latest cables does not mean that all other devices that can be integrated into the system will also work. In practice, the addition of an HDMI cable can provide more bandwidth, which is necessary for 4K.
To combat such negative effects when transmitting video in 4K format, it is recommended to use high-quality HDMI cables. For larger distances, it is necessary to use rubber bands. The HDBaseT™ standard is the basis for the 4K format.
Visnovok
Companies working on the production of 4K devices face the problem of conducting feasibility testing, as the rest are not widely represented on the market. TV receivers need 4K content, and content will be widely available once 4K displays are available. Moreover, these devices seem to be incredibly absurd. These companies are trying their best to solve these problems.
There are a lot of pseudoscientific facts around the world of wires, but the HDMI cable is the worst. The vibrator must swear that his product itself has a high resolution and clear sound, and can also drive out the devil from evil spirits that will rediscover your possession.
In truth, may it be HDMI cable– from a copy to the most expensive one – gives you approximately the same vividness of the image, since the skin from them may meet the most common criteria. However, due to the same characteristics, it is not possible to note that all HDMI cables are the same.
Use standard and high-speed cables. Older models that comply with standards 1.0 to 1.4 have much lower transmission speeds (1.3 Gbit per second, up to 10 Gbit for high speed ones). Newer HDMI 2.0 cables reach 18 Gbps, but are more suitable for new technologies. In addition to these features, it is possible to increase respect for durability, change the flow of other characteristics. To make your selection easier, we have seen 5 Shortest HDMI cables.

KaterinaHDMI is a technology for direct transmission of a digital signal that can be converted into images, video and audio. Today there is the widest transmission option and is available for almost everything computing technology where video information is transferred - from smartphones to personal computers
The port has 19 contacts for all variations. The connector is also divided into several types, which require purchasing the necessary cable and adapter for the new one. And these types:
Types of ports can be distinguished from each other by a different appearance or by special markings in the same Latin letter (not on all ports).
Information about the additional cable
For wide use, HDMI cables are sold for lengths up to 10 meters, but can be extended up to 20 meters, which is completely suitable for the average consumer. Retail enterprises, data centers, IT companies for their needs can purchase cables of 20, 50, 80 and run over 100 meters. For homemade bath It’s not a good idea to buy a cable “from stock”; a 5 or 7.5 m option will be enough.
Cables for home wireless stations are mainly made from special media, so that they can easily carry the signal to small villages. However, the storage capacity of the copper is made according to the type of copper used for making the cable, and its type.
For example, models made from specially treated copper, branded “Standard”, with a thickness of approximately 24 AWG (with an area of diameter equal to approximately 0.204 mm 2) can transmit a signal to a distance of no more than 10 meters at the separation 720×1080 pixels with a screen refresh rate of 75 MG. Similar cable, except for the technology High fluidity"(Can be set to High Speed) with a thickness of 28 AWG (area in diameter 0.08 mm 2) the building can already transmit a signal of 1080 × 2160 pixels with a frequency of 340 MHz.
Change your attention to the frequency of updating the screen on the cable (this is indicated in the technical documentation or written on the packaging). For comfortable viewing of video and video, the human eye clocks around 60-70 MHz. Therefore, you need to chase the numbers and the strength of the signal that is displayed only in situations like:
- Your monitor and video card support 4K resolution and you would like to use their capabilities 100%;
- If you are professionally involved in video editing and/or 3D rendering.
In order to ensure the flexibility and strength of signal transmission, it is better to buy the cable with a small deposit. If for any reason you need a larger model, then it is better to pay attention to the options with the upcoming markings:
HDMI versions
Together with the combined efforts of six great IT companies, HDMI 1.0 was released in 2002. Today, the American company Silicon Image is engaged in almost all further improvements and development of this connector. In 2013, the birth came out on its own current version– 2.0, which is not possible with other versions, it is better to buy an HDMI cable for this version only if the port on your computer/TV/monitor/other equipment is also This is this version.
The recommended version before purchase is 1.4, which was released in 2009, but is also limited to versions 1.3 and 1.3b, which were released in 2006 and 2007, and is the most advanced. Version 1.4 may include modifications – 1.4a, 1.4b, which is similar to 1.4 without modification, 1.3, 1.3b versions.
Cable types version 1.4
If this version is not recommended before purchasing, then we will take a look at this report. There are five varieties: Standard, High Speed, Standard with Ethernet, High Speed with Ethernet and Standard Automotive. Let's take a look at their skins below.
Standard – suitable for connecting non-vibrating home appliances. Supports separate content in 720p. It has the following characteristics:
Standard with Ethernet - has identical characteristics to the standard analogue, the same performance - it supports Internet connection, it is possible to transfer data at a speed of no more than 100 Mbit/s in two directions.
High-quality or Speed High. It is supported by Deep Color, 3D and ARC technologies. I’ll stay and look at the report. Audio Return Channel – allows you to simultaneously transmit video and sound directly to someone else. Previously, in order to achieve high-quality sound, for example, on a TV connected to a laptop, you needed to use an additional headset. The maximum working resolution is 4096×2160 (4K). The following specifications:
- 5 Gbit/s – maximum throughput threshold;
- 24 bits – maximum color depth;
- 165 MP - the maximum range of frequencies allowed.
High-quality version with Internet support. Internet data transmission speed will also be 100 Mbit/s.
Standard Automotive – is used in cars and can only be connected to E-type HDMI. The specifications for this variety are similar to the standard version. The fault is that the protection stages are deprived of movement and an ARC system is installed, which is absent in a standard wire.
The characteristics of the material, the material of preparation, and the flexibility of the folding, as written here, are important and important. Speed up your tributes in order to spare a little bit and vibrati best option. List of recommendations:
- The wiring has been expanded so that cables with gold-plated contacts conduct the signal more quickly. This is not the case, gold plating is applied to protect the contacts from moisture and mechanical inflows. Therefore, it is better to choose conductors with nickel-plated, chrome-plated or titanium coatings, as they will provide better protection and be cheaper to construct (including titanium coating). If you use a cable in your home, there is no need to buy the cable with additional contact protection;
- Those who need to transmit a signal at a distance of more than 10 meters are advised to take note of the availability of a built-in repeater to strengthen the signal or to add a special booster. Change the value to the cross-cut area (appears in AWG) - the smaller the value, the faster the signal will be transmitted to distant stations;
- Use a special protectant to protect the cables from the screens or the cylindrical type. It is designed to maintain optimal transmission speed (prevents the appearance of distortions) on even thin cables.
To make the correct choice, you must check all the characteristics of the cable connected to the HDMI port. If the cable and port are not consistent, you will need to either buy a special adapter or completely replace the cable.
A familiar situation: the seller modestly approaches the salesperson who is purchasing a new HD TV, and she offers further assistance. Then you will need to pay attention to the HDMI cables required for the selected TV. But the price is high - 60 or 70...
A familiar situation: the seller modestly approaches the salesperson who is purchasing a new HD TV, and she offers further assistance. Then you will need to pay attention to the HDMI cables required for the selected TV. However, their price is high - 60 or 70 dollars, and sometimes more than 100 dollars. (For just a few pennies you can buy an inexpensive player and a bunch of Blu-ray discs!) The seller confirms that these are special cables. Miracle cables. Cables are absolutely necessary to cut out the unnecessary rigors of watching movies in your home theater. However, for many people who have home cinemas, everything is a complete disappointment.
On the right, for most HDTVs there is absolutely no difference between the HDMI cable and the cost of 3 dollars. from a brand name, available from Amazon.com, and a Monster cable ($120) from your local electronics store. We conducted preliminary testing of five different HDMI cables, ranging in price from less than $5 to $100, to identify the advantages between cheap and high-cost cables.
HDMI Basics
We must first remember that HDMI is a digital standard. Available as component video, composite video, S-video or coaxial cable, HDMI signals are subject to noise and loss of clarity in the world of their progressive attenuation and increasing distortion. If a digital signal such as HDMI contains enough data to be accepted, its form will be updated. If there are not enough data, the signal simply disappears. Failures in signal processing and transmission can lead to blockages or a blank screen, but in general the HDMI signal is displayed at all outputs as long as it successfully reaches the receiver. The assertion that expensive cables will provide greater precision in video and sound is absolutely undeniable; With the same success we can say that you can improve the appearance of YouTube videos on your laptop screen by purchasing Ethernet cables. From a technical point of view, this does not hurt the thirsty sense.
This, however, does not mean that all HDMI cables are of equal value in any situation. HDMI specifications range from data transmission capacity to cable characteristics.
All cables that meet the exact HDMI specification (version 1.4a) will support 3D video, 4K resolution (approx. 4000 x 2000, or approximately four times higher not detailed in line with the accurate 1080p HD standard), data transmission via Ethernet channels . To be consistent with skin conditions, this may require increased bandwidth, and the capabilities of older HDMI cables (and all older HDMI devices) such as HDMI 1.3b and previous disadvantages. Creation of 3D video is a single mode needed by most users. Ethernet over HDMI is vikorized mainly in Merezheve obladnannya replacement of primary Ethernet or WiFi channels (which are installed in most common electronics devices). The audio return channels are not necessary in most situations with sound systems (this can be corrected by running an audio cable to the system). At this time, live displays and devices made from separate 4K units are not available (the price of an available 4K projector is over 75 thousand dollars). All types require an unambiguous power supply to ensure the cable. this function. There is no talk about clarity or a clear signal.
However, in some situations, it is important to add more power to the cables and try to maintain the strength of the signal so that most HDTVs do not experience interruptions. If you intend to use an HDMI cable longer than 3 m, make sure to use insulation to avoid interference with the signal. For cables longer than 1.8 m, the problem is not present in the network, but as the distance between multimedia devices and displays increases, the signal shape changes and sensitivity to magnetic transients increases. If the distance extends 9 m, the HDMI Licensing Committee recommends that you boost the signal or consider an alternative solution, such as converting HDMI over Ethernet. At heights close to the maximum, signal stability can be improved due to greater isolation and high vigor collection of expensive cables. However, if the distance between the Blu-ray player and HD TV is 9 m, it’s better to think about rearranging the furniture. Or simply use technology that is insured to transmit signals to more significant areas.
Another thing to keep in mind: the price of HDMI cables will always be the same in most stores. Go to Best Buy or Radio Shack, and you'll end up paying $40 for a 1.8-meter HDMI cable. In stores with low prices, such as Wal-Mart and Target, the average price of the cheapest and easiest HDMI cables is no less than $15. Prices on the Internet are much lower. Amazon.com and Monoprice.com have much cheaper cables than Wal-Mart. Both sites sell dozens of different types of HDMI cables for $1.50. Use the simplest HDMI cables or products from unknown distributors, otherwise they are completely suitable for most HDTV users. We can confirm this with all the evidence, the fragments of the stench protested them at the PCMag Labs laboratory.
Cable testing
We had five cables, including the HDMI/Ethernet combo set Monster Cable 1200 Higher Definition Experience Pack (recommended price: $119.95), which, however, can be purchased for $79.95. on Amazon.com; Monster Cable HDMI 500HD High Speed Cable (recommended price: 59.95 dollars, in the Amazon online store - 52.62 dollars); Spider International E-HDMI-0006 E-Series Super High Speed HDMI with Ethernet (recommended price $64.99, Amazon price $45.29); Cables Unlimited 6-Foot HDMI Male to Male Cable (PCM-2295-06) for $3.19 at Amazon; OEM cable without marking from the Monoprice store, supplied from Belkin, but not comparable to the standard HDMI cables from this company (single price - 3.28 or 2.78 dollars when purchasing 50 cables).
We have been able to test even expensive HDMI cables, such as the AudioQuest series cables with a retail price of up to $700.
Based on specifications, Monster Cable HDMI cables are the best. Of course, this is explained by the fact that Monster Cable is one of several companies that has specified the characteristics of its product. The information about cables Spider International and Cables Unlimited is very poor, and for the nameless cable there are no necessary data, except 28 AWG (American Wire Gauge). This number simply indicates the diameter of the wire that is used in the cable (28 AWG is the standard value, but there are also cables with sizes 26 or 24 AWG). Compliant with HDMI standards, all HDMI 1.4 cables are designed to provide a throughput of 10.2 Gbps. The nominal capacity of the Monster Blu-Ray 1200 Higher Definition Experience Pack cables is 17.8 Gbps. The other characteristics that are really important are: the flexibility of HDMI 1.4 and the capabilities that are significant. Increased capacity is of no importance for HDTV signals. The capacity may be limited to 4K video, but since the current display for current HD TVs is 1080p, the power supply will be limited.
Please find some cable that confirms HDMI standard 1.4 z access control 10.2 Gbit/s (and this is very satisfactory for all cables that are compliant with the 1.4 standard). It is significant that we have not found a cable that is not crazy with the 1.4 standard.
For the purity of the experiment, we only used 1.8- and 2-m cables, so that the excess did not affect the test results. In all tests, the Sony Bravia KDL-46EX720 3D HDTV and LG BD670 Blu-ray player were used. Bullets installed standard setup TV image, and the Blu-ray player is set to 1080p video output. For the skin cable, we tested three different tests: assessment of technical strength, “slip” video test and 3D test.
To evaluate technical brilliance, a Blu-ray disc was tested using HQV reference video tests. For the skin cable, a set of different HQV video tests was installed to test the numerical methods of image processing, frame synchronization and color correction functions. Numerical patterns and animations are used in tests to highlight the display characteristics. HQV tests successfully tested all five cables, with one fault common to all cables (probably caused by a malfunction of the HD TV or Blu-ray player): the 2-2 reversal seemed slightly survivable. This small amount was not included in the cable ratings.
The “slip” video test was conducted using five volunteers from the PCMag Lab. They showed one scene from the movie “Predators” on a Blu-ray disc with separate cables. Until the end of the test, they were not informed of the brand of cable that was being tested. No one found any significant difference between 3 and 120 dollar cables. However, we noticed a noticeable phenomenon: the screen looked a little darker and less vibrant when connected to Blu-ray playback via the optional Monster Cable 1200 High Definition Experience Pack. Through the cable, the HDTV receives a new signal with 12-bit color; This way, fewer colorful parts came through the high-speed Monster cable. However, the difference is very small, and it can be done by calibrating the HDTV.
Let’s say we’re captivated by the 3D movie “Avatar” on Blu-ray Disc, so we need to check it out standard function HDMI 1.4: 3D content transmission. All cables, including the cheap $3 cable, were designed to support 3D video on HDTVs.
Many HDTVs make do with a compact configuration, without having devices on large displays, so there is no reason to spend more than 10 dollars on the purchase of an HDMI cable, not even about 100 dollars. None of the possible achievements of expensive, overhead engineering solutions will ever appear on your home theater screen. Otherwise, if you are using a 4K projector or Blu-ray player or HD TV located in different parts of the 7th Hall, or if you want to demonstrate your magnificent home cinema to your guests. Simply connect your Blu-ray player, cable box or video game system to your HDTV, browse great stores and popular brands, and look for great deals online. And with the money you save you can buy new ones electronic devices And eat them one by one.
