Use Wisdom hdmi vga cable, electrical goods can be taken directly from the DVI signal source, reliability is very high. Products made at the receiving end of a very delicate connector, when the need to wear a tube connectors can be disconnected, etc.

HDMI interface specifications in digital form can transmit uncompressed high-definition video and multi-channel audio data while maintaining the high quality of the case. Its superior displayport to hdmi cable performance beyond all previous products.
HDMI specification connectors use a single connection, replacing the complex cable behind the product.
Interface cable using the HDMI specification does not limit the length. For example: DVI cable length can not exceed 8 meters, otherwise it will affect the picture quality, and compliance with the HDMI specifications mini displayport cable of the product is not the problem.
The HDMI specification can be used with broadband digital content protection (HDCP), in order to prevent copyrighted audio and video content from unauthorized copying.

VGA extension cable
Home in a variety of computer, digital, home appliances can be connected together to use, but Wisdom Vga extension cable equipment in the bedroom, den, some also in the living room, they are PCB spring terminal block moving up on the very trouble, use an extension cord it, even the most long extension cords are out of reach. Fortunately, when the home renovation embedded a network cable, then the equipment of each room you can use it to "connect" the.Such as televisions, projectors and other video devices are generally connected via VGA and computers, we can modify the network cable into a long VGA cable, so do not move the computer, you can watch the content on the bedroom computer in the living room. First, use a knife to cut open the cable sheath, length of about 3cm, revealing eight different plug in terminal block colors of tiny wires. Use wire strippers to each thin strip of insulation around 1cm. Then deal with the other end of the network cable using the same method. Got a pair of detachable VGA adapter, you need to select the appropriate male or female depending on the interface type of device. The next step is welded, open VGA connector housing, a control pin connection diagram will correspond to a small line of welding cable and VGA connector.

hdmi cable wire is used to transmit high-definition multimedia video signal
hdmi cable can be high-quality transmission of uncompressed HD video and multi-channel audio data, the maximum data transfer speed of 5Gbps. At the same time without the signal before displayport to hdmi cable transmission / A or A / D conversion, can guarantee the highest quality audio and video signal transmission. Transmission principle HDMI cable 2HDMI data cable data lines 1HDMI
hdmi cable line has a "plug and play" feature, automatically, "negotiation", automatically selects the most appropriate video / audio formats between the signal source and the display device. Volume DVI HDMI interface, compared with the smaller, and can PCB Spring Terminal Block simultaneously transmit audio and video signals. DVI cable length can not be more than eight meters, otherwise it will affect the picture quality, but HDMI can transmit as far as 15 meters. As long as an HDMI cable, you can replace up to 13 analog transmission line, a home entertainment system can effectively solve the tangled mess behind the wiring problem.

Using yourself infinite wisdom of the VGA cable
Unlimited extension of yourself making clever use of the network cable extension cord Decrease font Increase font Home in a variety of computer, digital, home appliances can be connected Barrier terminal block together to use, but Wisdom vga cable equipment in the bedroom, den, some also in the living room, they are moving up on the very trouble, use an extension cord it, even the most long extension cords are out of reach. Fortunately, when the home renovation embedded a 15 pin vga cable, then the equipment of each room you can use it to "connect" the. VGA extension cable such as televisions, projectors and other video devices are generally connected via VGA and computers, we can modify the network cable into a long vga extension cable, so do not move the computer, you can watch the content on the bedroom computer in the living room . First, use a knife to cut open the cable sheath, length of about 3cm, revealing eight different colors of tiny wires. Use wire strippers to each thin strip of insulation around 1cm. Then deal with the other end of the network cable using the same method. Got a pair of detachable VGA adapter, you need to select the appropriate male or female depending on the interface PCB Screw Terminal Block type of device. The next step is welded, open VGA connector housing, a control pin connection diagram will correspond to a small line of welding cable and VGA connector. Note welding wire well insulated, do not short-circuited. After the welding is good, then close the lid on the joint, you can achieve a long-distance transmission of video signals. If your USB device is relatively large, inconvenient to move, but also a shorter USB cable, you can also use the network cable to create a USB extension cable.
First cut the original USB cable is designed to get two USB connectors. Respectively the network cable and the USB connector cable peel, due to the small USB cable is only 4, while cable has eight, then the extra white line network cable can be cut off. Before welding in order to put in the back of a small shrink tube insulation.

HDMI sources
HDMI from DVI interface technology, they are primarily based on Silicon Image's TMDS signal transmission technology as the core, which is why the HDMI interface and DVI interface adapter PCB Screw Terminal Block conversion through reason. Silicon Image's HDMI eight sponsors are the only IC design and manufacturing company, is a leader in the field of high-speed serial data transmission technology, because the TMDS signal transmission technology to be mentioned below is that they developed, so here is a little mention it.
TMDS (Transition Minimized Differential Signaling) is also known as Transition Minimized Differential Signaling refers to the XOR and XNOR logic algorithms, such as converting the raw signal data into 10, after the first 8 data from the original signal obtained by the operation, after 9 indicates operation mode corresponding to the first 10 to a DC balance (DC-balanced, that is to ensure that the channel encoding process in the DC offset is zero, the level conversion achieves matching between different logical Dvi to hdmi adapter interfaces) conversion data transmission to the differential transmission mode. This algorithm is such that the upper punch and the lower transition of the transmission signal offset is small, tends to be DC-balanced data transmission, the signal transmission line for the electromagnetic interference is reduced to improve the speed and reliability of signal transmission.

What is a vga cable
Card information will eventually be processed output to the monitor, video card output connector is a bridge between the computer and the monitor, which is responsible for the display micro usb 2.0 cable output corresponding to the image signal. CRT monitors on the design and manufacture of reasons, can only receive analog signal input, which requires graphics input analog signal. vga cable analog signal is output on the graphics interface, VGA (Video Graphics Array) port, also called D-Sub connector. Although the LCD monitor can receive digital signals directly, but vga to hdmi cable many low-end products in order to match with the VGA interface card, which uses the VGA connector. VGA interface is a D-type interface, there are above 15-pin space, divided into three rows, each row of five. VGA graphics card interface is the most widely used type of interface, the vast majority of graphics cards with such an interface

DVI and HDMI Mistakes
1 Myth: DVI and two HDMI interfaces quality vary greatly
Under the existing circumstances, the same resolution, DVI and HDMI picture quality was no significant difference between the two interfaces, but with the development of the HDMI interface than DVI interface can provide more functionality.
2, Myth: HDMI interface can transmit hdmi wall plate audio signals, DVI can transmit audio signals
DVI pin from the above definition can be found, there is no use of empty data pins. As 4,5,12,13,20,21 these pins, graphics card makers can use these empty needle transmission of audio signals. However, due to the DVI standard does not define a special pin to transmit crossover ethernet cable audio signals, so this is something the manufacturers themselves do set standards and interoperability between different vendors are not common. Also, because most manufacturers prefer to use advanced HDMI interface to transmit audio, DVI can transmit audio function was abandoned.
