The advantages of HDMI

HDMI advantages comparing with the analog video interface existing such ascomposite, S-Video and video component:

1, quality:HDMI  is a digital interface, since all of the simulated connection (such ascomponent video or S-video) requirements in the converted from analog to digitalwithout loss, so it can provide the best video quality. This difference in the higherresolution, such as 1080p is particularly evident. Digital video than component video is more clear, eliminate the discovery component video in softness and tailing phenomenon. Such as text of this kind of small, high contrast detail the difference will be developed to the extreme.

2, ease of use: HDMI in the single cable integrated video and multi-channel audio,eliminating the use of the A/V system in the multi cable cost, complexity and chaos.This is particularly useful in upgrading or add equipment.

3, Gao Zhineng:HDMI supports video source (such as a DVD player) and bidirectional communication between DTV, the realization of new functions, such as automatic configuration and a key player. By using HDMI, equipment for the connection of the automatic transmission display the most efficient format (such as 480p vs 720p, 16:9 vs 4:3)? From the consumer need to scroll all the formatting options, to guess the best viewing format trouble.

4, high definition content ready: support for HDCP HDMI devices to access highdefinition content high, we bring some comfort to me. HD-DVD and Blu-ray have for today's high definition movie delayed starting image resisting marking (also calledcontent protection mark), to help minimize the potential problems caused by the conversion, but is expected to start this tag within a few years, means that the futureof high definition movie will not pass not protected interface (such as analog element)broadcast in high definition.

WISDOM vga cable and cable industry still wary of the drawbacks

With the introduction of five- integrated transportation system planning , the state railway construction policy warmer, promote urban rail transit construction across the news heard booming transportation construction , for cable companies is undoubtedly favorable . However, the same should also see that the cable industry development and construction of rail transit is not completely synchronized.
WISDOM vga cable users centralized monopoly WISDOM hdmi to dvi adapter  enterprises decentralized , less large central enterprises , no international brands such as traditional cable market criticized in the field of rail transport cable still exists . Compared with traditional cable market , due to the metro cable , marine cable and other cables strictly retardant , halogen-free , smoke suppression requirements ; country regional differences, such as the hot and humid climate of the South and the high and low voltage power cables and more ants environment , mica insulation fireproof cable accessories , mineral insulated cable fire , leakage coaxial cable and other high-end products , our R & D capability is still less than the current low level of popularity , in part dependent on imports of high-end products .
In addition , WISDOM vga cable due to the cat5e patch panel  rapid development of rail transport market , capable of producing less sophisticated end product companies , one of the few companies with limited human and financial resources, in order to meet customer demand, intense side of the purchase of equipment , additional human resources side , resulting in increased fixed costs , a shortage of liquidity , the objective follow-up research and development capabilities of the enterprise caused some impact . The small business , capital, technology, personnel are relatively weak, the product quality can not be guaranteed due to its low price , the market tends to be dominated by them . These companies did not form their own core competitiveness , it is difficult to resist the impact of the market.
Then, in the field of rail transport , the cable companies WISDOM fiber optic cable  should be alert to how the drawbacks of traditional markets , namely domestic enterprises should improve their technical level, the high-end product development and foreign cable snapping ; second is to break the monopoly of the current technology , so that more enterprises to participate come ; Third, production of cable products should be in accordance with national standards.

Process characteristics vga cable wire product manufacturing

Wire and cable manufacturing process characteristics: the great length of the combination of continuous production mode superposition large continuous length overlay combination mode of production, the impact on the global wire and cable production and controllability, which involves and affects:
A production process and equipment layout workshop equipment required by the various product requirements and reasonable process emissions, so that the various stages of semi-finished products, sequential flow. Device configurations to consider and balance the different WISDOM micro usb connector  productive capacity, and some equipment It may be necessary to configure two or more units, abilities production capacity of the production line can be balanced. vga cable so reasonable matching combinations and arrangements equipment production facilities, according to the product and production capacity necessary to balance considered.
2 production organization and management of production organization and management must be scientific and reasonable, accurate and careful, meticulous, the operator must be meticulously executed according to process requirements, vga cable any link problems will affect the process of smooth, affect product quality and delivery. especially multi-core cable, one  WISDOM rca video cable pair or the basic unit length is short, or quality problems, the entire length of cable will be enough to cause scrapped. Conversely, if a cell is too long, it must be sawn wasteful .
3 large length of continuous quality management overlay portfolio vga cable production, so that any one part of the production process, instantaneous little problem, it will affect the whole cable quality. More quality defects occur in the inner, and did not discover the termination of production , then the greater the losses caused due to the production of wire and cable products unlike assembled, you can open other pieces of heavy equipment and replacement;. either a part or the wire and cable process quality WISDOM dvi to hdmi adapter  problems, these cables is almost irreversible and irreparable. afterwards disposal are very negative, not sawn disposal is downgraded, or scrap the entire cable. unable to open the heavy equipment. quality wire and cable management, it is necessary throughout the entire production process. quality management and inspection department To tour the entire production process inspection, the operator self-inspection, mutual inspection process from top to bottom, this is to ensure product quality, and means an important guarantee for improving economic efficiency of enterprises.

Some major role vga extension cable for

VGA extension cable is a few empty legs . 5 m of the line is entirely possible . If your graphics card is DVI interface before , then you need to set up a second monitor and the first monitor the same. Some  WISDOM mini usb connector vga extension cable dual interface display there is a button to select the input interface can be extended is possible bq, but there may be too long too 8406quy 9186 that resulted in a low signal attenuation to below the detection threshold of a TV cable TV to get in front of the notebook , bought the line alone try, to determine which lines are easy to use , if no problem , then it should be too much to extend the signal attenuation is possible, but WISDOM pcb spring terminal block  there are may be too long , resulting in signal attenuation too , vga extension cable to the TV so low below the threshold of detection . That is a problem with your line quality connection is not wrong but the extension cord should be increased with the length of male and female that point does not cause signal interruption of this phenomenon is normal, because VGA is an analog signal transmission , the longer the line the usb 2.0 cable  more  attenuation powerful.
At the same time the quality of the line attenuation great impact , it is recommended to buy a good brand is the best VGA extension cable
