They are expensive HDMI cables worth the price?

They are expensive HDMI cables worth the price?

Hdmi

If you have recently purchased a new piece of home entertainment equipment, then no doubt the seller is also trying to sell an expensive HDMI cable with the new product. But why pay more for a "high quality" HDMI cable when you could be a bog-standard cable for a fraction of the cost? This article aims to provide expensive HDMI cables if you actually see the benefits, or you are just another way to squeeze a little money 'moreThem.

HDMI is a relatively new digital standard for quick access to all new AV equipment. No longer do you need a set of cables with HDMI, there is only one cable, and run. So that HDMI is a digital format, then surely there is no advantage in buying an expensive cable, certainly all the cables offer the same quality and the only thing you have to pay extra for a brand?

Well, unfortunately, is notso simple because not all HDMI cables are the same! Although the format is still relatively young, has already been some major updates after the initial introduction - in fact, these revisions have fewer updates itself - the only more confusion. Of course, the cables meet the latest specifications and more expensive than the old cables that match specific to the elderly, it is not just a matter of selecting a cable on the price. They must alsoexamine which of your equipment specifications to optimize performance requires, as you will find that you have a cable with a lower specification impair the quality of sound and image. In some cases, the device will not even work with the cables can be so sure to see the manual, you need to check the version of HDMI.

Another thing to keep in mind that the HDMI signal can be a strong demand to bring the cable itself, therefore less expensive cables can not offer the same qualitymore expensive than cable. This is especially true for longer cable lengths: the longer the cable, the easier it is for the distorted signal. Therefore, if you need a long cable, verify that the cable has been manufactured to a high standard with quality components. Cheaper brands tend to have lower quality cables that are vulnerable to perturbation signals for use as supplies of poor quality.

Otherwise, it should be noted that while the HDMI platform, nothave some features error correction, which does not completely eliminate error. When a compatible device receives an error, try to estimate what would have been the signal, but if the signal is not transmitted correctly in the first place for the rectification of error can do little. HDMI signals are certainly less prone to error, but it can still happen, so therefore a higher quality cable would help ensure that the odds were reduced for it.

Wouldbe great if all the HDMI cables that offer the same quality and performance, but unfortunately this is not the case. No matter what market you are in there have always been products that have a high quality, independently produced and the cost of the products that were made to a lower standard, to be more accessible. The good news from a consumer perspective, is that the difference will be smaller, so if you are in terms of performanceneed an HDMI cable I would definitely recommend that you make sure that a good quality product, but there is no need to spend large amounts of money.

What is the difference between component and HDMI cables?

On a short section, not the cord indifferent. What is different is that in the case of component cables to convert the TV signal to analog component to digital. In the case of HDMI cable, the signal is already digital. So it may be a significant difference if your TV does not convert well.

Image quality aside, the reason why we recommend using the HDMI cable carries the signals is that HDCP is not component. If the source device, such as aCable box, the search for the HDCP handshake, and do not get it, it will output an HD signal. So if you want to watch HBO in HD from a cable box, you must use HDMI or DVI.

I use component cables. Then again, I was above $ 60 on it (gold plated, great conductors, often shielding, etc.) for both component video and audio channels. And, I bought a few years earlier were still in the HDMI cable. The difference in performance between the top-end component video cableand an HDMI cable is negligent. But if only standard RCA cables - as the company offers cheap cable TV for you - are not as good as the HDMI cable.

How the HDMI cable connections spread more and more, we are often asked: What is better HDMI or component video? The answer, as it happens, it will not cut and dried.

First, a note: everything is said here, as it appears for DVI-HDMI, DVI for consumer electronics devices less and less of alltime, not so often asked, but DVI and HDMI are essentially the same story, the image quality-wise. The main differences are that HDMI carries audio and video, and uses a different type of connector, but both have the same encoding scheme, which is why a source to a DVI to HDMI monitor, or can be connected and vice versa, with a cable DVI / HDMI cable, with no intervening converter.

The conclusion of this article - if you are not inclined to read all the details - iswhich is very difficult to predict whether an HDMI connection is better or worse image of an analog component video to connect. It will often be significant differences between digital and analog signals, but the differences are not part of the connection type and instead depend on the characteristics of the source (eg DVD player) and the display device (such as your TV). Why this is so, however, takes the discussion a little 'more.

Several peopleDay looking for a solution trying to HDMI interconnect to the outputs of the component via a connection cable for their high-definition equipment. Unfortunately, this is not a matter of reorganizing the right kind of cables and plugs. This is compared to a similar fundamental incompatibility issues like the upcoming digital broadcast digital TV switchover to receive respect for your rabbit ears current analog broadcasting signals. They are not compatible and can only confuse peoplelike the poor guy in the commercial register.

Component video is analog format. With analog signals, the signal voltage on the cable in wave format and how changes in wave height, what is important. Theoretically, there is an infinite number of values ​​between zero and maximum, variable wipers I had something like on an old Thunderbird. With HDMI or DVI format, these are based on digital signaling. Digitally as you have probably heard, uses ones and zeroswith a series of pulses all at the same height, and are present or absent. At the other end of the new set of information processing systems. Mounted on a 4-bit binary encoding can be one of 16 different values ​​of 4 1 and 0 as the group can have 16 different combinations. Equipment only at the end of the cable, the signal acquisition and is looking for analog waveforms would put out a total nonsense when he received pulses of 1 and 0

Some solutions are verysimple. When an HDMI or DVI on both boxes, use them. The difference between DVI and HDMI is that HDMI caries in addition to audio and video signals. But DVI is just as good and other than the cost of an additional audio cable, that will solve the problem. If you try to use the component outputs, because it is already linked to the HDMI connection, HDMI switch box that they are fairly cheap, where there are multiple HDMI cables on one side with a pin can outputother.

Components via a power analog signal is transmitted. HDMI is digital. Among other things, this has the following advantages: As long as the data is successfully transferred the perfect image of the incoming data into your TV. It is not a single pixel in the difference that erases the device 'submit' and what the TV will be reached. Component signals (such as all analog signals) may be of varying quality, and you can get interference.

So basically: At first glance, might seem the HDMI cablemore expensive than component cables, but it is not right. For the quality of the HDMI cable is requiered to the length you need together. If you have only a short distance (two or three meters) to cover a cheap cable offers the best possible result that can be achieved by any means ... is digital ... the cheap cable does not affect the image quality ... exactly as you use the Ethernet cable from your computer to connect to inet has no influence on image qualityVideo download / stream.

Of course this does not mean bad part: In favor of analog video connections is probably by far the best, but only HDMI has the advantage of not having to worry about the signal accidentally "touched" by external influences during the transfer. So if you can: HDMI is the best choice.
