In recent years, the HDMI standard has gained incredible abundance: this connector can be seen not only on TV but also on computer monitors.Through a cable with equal success, you can transmit audio and video.
It should be noted that the disclosure of the potential of all modern formats for high definition video it requires standard HDMI.Older cables simply can not convey so much information, and the amount of signal distortion when using them is too great.So today we'll talk about how to select the HDMI-cable.This theme is today very urgent.
Pricing Policy
known that the quality of the cable of this type will have to pay very, very much.And it is so annoying, the more many companies exaggerate the virtues of the product that comes to market them.Moreover, given the demand, which still falls short of that of the sale of hot pies, many manufacturers (and retailers - especially) try to sell even very average (so to speak) model cables for the transcendent prices.
Naturally, words like "gold contacts", "the highest data rate" and the like constantly flashing in the speech consultants.So how to choose the HDMI-cable?
Introduction to
first specify that for the transmission of information via HDMI-port differential digital signals are used.And this standard is considered to be copy-protected so that all the information is encoded on a fairly complex algorithm.In addition, this technology safely rescues from interference.
With some algorithms, maybe even a full recovery after a serious signal distortion during transmission.
Faults
If the cable is short, its technical condition and in good order, then the signal is passed without distortion or loss.When you use a too long cable or its quality is not too high (or both), the TV can not correctly interpret the received signal.There is a "failure", and the screen or monitor and stars of various sizes appear in light spots.
In the case where the received data is partly enough, the picture will be diluted by "failures" interference.But this is very rare, because most of the corrupted data will not allow the device to form an image.
Dispelling myths
What are we all talking about?It is necessary to understand one simple thing: all the words of "the differences in picture" with different HDMI-cables are in the same plane as the "warm tube sound."
cable can not exert any influence on the quality of the digital (!) Of the signal!Data or tested by forming pixels of the image, or they are not tested at all.Someone might object, thinking of sequins during playback.Alas.These symptoms indicate deterioration of the cable: see "snow" or "sparkles", prepare to be without the image at all, since the signal may soon simply does not pass through the defective portion.Note that the cost of production for such phenomena does not affect: the smallest flaw can be found in the cable for $ 10, and "choosing music lover" for $ 1,000.
about the reliability of signal transmission
Note that largely depends on the quality of the transmission distance, if we are talking about a couple of meters, you can take any cable.Long same variety (more than four meters) must be made subject to strict quality control, since the slightest defect will result in a loss of signal.
So how to choose the HDMI-cable when you really need the maximum length of transmission?This need may arise in the case where you plan to broadcast the video signal from your computer to your TV, located somewhere in the bedroom or the summer terrace.To know the answer to that question, we suggest that you read all of the following.
Types HDMI-cable
There are four main types of cables HDMI: velocity models of the first and second category.Where are the two options?It's simple: each cable is the first or second type may or may not support Ethernet.And what HDMI cable is particularly suitable for high-definition?
All models of the first category is theoretically designed to transmit video up to 1080 p.Accordingly, the second type supports a higher resolution.A little trick: the majority of high-quality cables, the first category without a problem allows you to watch 1080 p, although technically they are, as it were, and not calculated.So if "string" for five dollars conducting such a signal is no reason to buy something more expensive there.Here's how to select the HDMI-cable, while not overpaying.
little about the frequency
Many sellers "catch" of potential buyers on the claim, though expensive models "fit" for the frequency of 200 Hz.This is a provocation and lies.Translation from 100 Hz to 200 Hz is done exclusively by the receiving device and cable because the process does not even have a distant relationship.The only exception - 3D-view movies from the disc Blu-Ray.And what a HDMI-cable select for 3D?Only one that complies with HDMI 1.4.
real differences of cheap and expensive versions
Perhaps the only difference between expensive and cheap models is the presence of a thicker and "capital" slippage, better connectors.That's only worth it to overpay for the money that they ask for sellers?The cable is stiffer, the easier it pops out of the socket.This is especially true in cases where a TV set-top box or stand close to the wall.
In addition, the weight of a long cable with heavy insulation over time can lead to damage and deformation of the port.
Select the cable set-top boxes
All this concerns mainly TVs.Is there any nuances in the case of consoles?What is HDMI-cable select for the Xbox 360?Let's find out.At the same time again we debunk some of the stereotypes that are popular with our vendors.
There is an opinion that is artificially supported and inflated sales consultants that there is a special HDMI-cable.How to connect - there is no difference, but the course is and "gold plating" and "highly purified metals for manufacturing."As you might guess, this is just an advertisement.
course, do not buy cable on the collapse of 200-300 rubles, as the quality of its production under the big question.But take the model for 5000 rubles is also very stupid.Once again we remind that the length of up to four meters difference in Manufacturer no.Take for buying and check if the cable is something you are not satisfied, wear it for a replacement.
Conclusions
Surely we will not be mistaken if we say 99% of the needs of users.Most likely, you will need a cable 1.5-3 meters long to connect the set-top box, Blu-Ray player or monitor.With such a length of even the cheapest model will give the perfect sound and image.Even at large distances, cheap cables are often doing their job well, no different from his insanely expensive "colleagues."
So when "young and promising" the store manager offers HDMI for three or four thousand rubles, just pass by.Models for 300-400 rubles will prove just as good.
Here's how to select HDMI-cable TV.As you can see, not necessarily to pay for the amount of wild brand models, since no real improvement in sound and video you will not notice.The only exceptions (as we mentioned above) is the selection of cables for viewing of 3D-films.In this case, the cord passes through the vast amount of information, the signal has a high frequency.Standard models do not fit.
