HMI human-machine interface manufacturersSelect the HDMI cable for the display method, how to let the display display picture, in addition to the power cord, but also the display data cable, there are currently three main, HDMI cable, VGA cable and DVI cable. Now basically choose a display with hdMI interface (HD interface), so it is very important to choose a good HDMI line.
HDMI interface version
To select an HDMI cable, first look at the version number of the HDMI interface. HDMI interface version is different, bandwidth and support technology is also different, currently, HDMI line and HDMI interface can be divided into 1.3 to 2.0 versions, high version can be compatible with low version, so, when choosing HDMI line is best to match the HDMI interface, at least not lower than the interface version. If the version below the interface, you can not transmit HD impact, on the contrary, if higher than the interface version, although you can use, but you have to spend more money.
HDMI line certification
HDMI line is standard, so if there is certification mark, generally in the quality of no problem, there are currently two kinds of certification, one is HDMI certification, the other is Sinplay certification, both certifications as long as there is one, of course, if both certifications are the best.
Joints for HDMI wires
HDMI wire joints are generally gold-plated and non-gold-plated, gold-plated joints will have better corrosion, conductivity and high temperature resistance. So normally, there are gold-plated joints of the wire will be better, many of the gold-plated joints on the market use 24K gold-plated, brightness is relatively high, it is easy to distinguish. But that's not to say it's bad not to be gilded, because it's the PIN needle inside the HDMI connector that ultimately works during use, which is the main connection point.
This PIN pin is mainly made of tin bronze, in the production, will be on the PIN needle first nickel, and then gold plated, so, if the workist is better HDMI line, carefully look at the PIN pin, you will find three layers.
The process of HDMI wire
HDMI wire core is very important, the best is the copper core, copper core transmission capacity and transmission quality are very good, can prevent signal interference, while the signal in transmission will not have too much loss, there is also a inner core is alloy and iron made, of course, this is relatively poor. If you want to really distinguish this words can only be opened to see, but should not be a few people will buy a line back to break, so the author to introduce a relatively simple method, you can bend HDMI line, repeated bending several times, if more soft, is the copper core, if more hard is the alloy and iron core, but pay attention not to bend too much, alloy and iron core easy to break.
Of course, the current HDMI line core also has a certain development, some directly using fiber as the inner core. The benefits of using fiber here is not mentioned, today's broadband is basically fiber optic, so we should all understand, of course, fiber core HDMI line is very expensive, if not poor money recommended the use of fiber core HDMI line, if you need a longer HDMI line, but also choose fiber inner core, ordinary users generally choose copper core.
Weight of HDMI lines
HDMI line has thick, some thin, how to choose? Normally, the same brand, the thicker the line, the better the transmission performance, and more stable, but it is best to choose the brand line, some miscellaneous lines are added a bunch of miscellaneous things, so that the line looks thicker only, so choose HDMI line when the best choice of brand, foreign general is magic sound, line Saint, BG, Gefen, Philips, SONY and so on
Thin HDMI line is absolutely not available, this line for data transmission, the signal will be relatively poor, HDMI wire wire regulation (AWG), the larger the number is finer, this in the purchase of attention, such as the same brand, 20AWG will be better than 30AWG.
Take a summary.
HDMI line production costs are relatively high, so the normal more expensive the better, but the premise is the quality of the better, but the premise is that the quality of the pass, how to choose an HDMI line to believe that after reading the above content is also very clear, the first version is appropriate, its second is suitable for your use of the environment, and then the line's brand and quality to be guaranteed, if the above conditions are in line, that is a good HDMI wire.
