How to use the vga cable?

 VGA connector is the output of the analog signal on the graphics interface, VGA (Video Graphics Array) port, also called D-Sub connector. Although the LCD monitor can receive digital signals directly, but many low-end products in order to match with vga extension cable  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 cable interface is the most widely used type of
 Most computer with an external display is through analog VGA interface display image information, the computer digitally generated internally between devices is changing the video card in a digital / analog converter for the R, G, B three primary signals and lines, field sync signal, the signal is transmitted to the display device via a cable. For analog display device, such as an analog CRT display, the signal is sent directly to the appropriate processing circuitry, the drive control tube to generate an image. As for LCD, dvi cable and other digital  display devices, display devices need to configure the A / D (analog? Digital) converter, the analog signal into a digital signal. After a D / A conversion and A/D2, inevitably result in some loss of image detail. VGA interface used in CRT monitors is understandable, but the loss of connection for image display devices like LCD, the conversion process will display a slight decline.interface, the vast majority of graphics cards with such an interface.

How To extend hdmi extension cable?

HDMI cables have simplified our electronic lives, but things get tricky when those cables have to cover a long distance.
Let’s give the mini HDMI cable some credit. It helped clean up the tangled mess of wires behind our TVs, gave us a way to quickly link a stunning range of devices with a new generation of displays and provided a sturdy backbone for the HD revolution. But for everything this unassuming all-in-one cable can handle, sometimes it comes up short.
Like many video, audio and data cables, hdmi extension cable can suffer from signal degradation at longer lengths—50 feet is generally considered the maximum reliable length. And it’s rare to see an hdmi extension cable longer than 25 feet in a store. Even online, vga to hdmi cable more than 50 feet long can be hard to find. If your TV, set-top box and other AV equipment are all on the same piece of furniture, this isn’t much of a concern. With a collocated setup, you’ll probably never need more than 6 feet of cable at a time.
But HDTVs have introduced a whole new way of arranging home theater gear. Flat screens are increasingly thin and lightweight, and their picture-frame profiles make them perfect for hanging on walls. Similarly, HD home theater digital projectors are now affordable enough for nongazillionaires to set up a basement cinema. A clean installation of either of these setups generally requires a bit of in-wall wiring, sometimes even from one room—an AV closet, for instance—to another. And when you’re fishing wires up into ceilings, over doors and under floors, the necessary spool of cable gets long quickly. 

About vga extension cord

CRT monitors on the design and manufacture of reasons, can only receive analog signal input, which requires graphics input analog signal. VGA mini usb connector‍ is the output of the analog signal on the graphics interface, vga extension cable (Video Graphics Array) port, also called D-Sub connector. Although the LCD monitor can receive digital signals directly, but many low-end products in order to match with VGA interface card, which uses the VGA connector. VGA interface is a D-type interface, there are above 15-pin space, cate5e network cable‍ 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.

vga extension cable design specifications

VGA, A refers to the "array (array)" instead of "converter (adapter)", because it was designed from the outset as a single integrated chip, to replace Motorola mini displayport cable‍ and dozens of discrete logic ISA combination chip master, this design before the MDA, CGA and EGA use. This feature vga extension cable allows it to be easily cloned into PC motherboards among cat6 patch cord‍ need additional video memory, oscillator, and a RAMDAC, will have a display. IBM's PS / 2 PC series is the use of the VGA placed on the motherboard design.

hdmi extension cable features an infrared receiver

hdmi extension cable infrared receiver features: 

1 External colloids using electrical terminal block‍, and add coloring, play better shielding effect. 

2 senior internal IC chip imported from Germany and PD, achieve longer distances and more sensitive receiver acceptance angle, to ensure the 21 pin flat scart cable‍ and consistency of performance. 

3 fixation using high-temperature aging process, to ensure infrared receiver bracket rust during storage.

hdmi extension cable High Definition Multimedia Interface

hdmi extension cable High Definition Multimedia Interface (English: High Definition Multimedia Interface) is an all-digital video and audio transmission interface, you can send uncompressed audio and video signals. 

HDMI cable supports uncompressed all-digital audio / video, a single cable can transmit high-definition, all-digital audio and video content, based on the core technology of the latest generation of TMS, with thousands of Cat6 keystone Jack‍ per second of bandwidth content can be combined with high-definition video and multi-channel audio data to a single interface, support to the (1600 * 1200) UXGA resolution, the maximum transmission speed of 5Gbps, thus truly "HD Emergency, which greatly simplifies the wiring. widely used in LCD TVs, plasma 8 port HDMI switch‍  rear projection TVs, LCD computer monitor crystal and home digital video systems HDTV (hard disk player), digital set-top boxes, DVD, projectors and other equipment in the data center control, information distribution, high definition digital signal needs a place conference room presentation, school and corporate training, HDMI cable is one of the most capable high-definition audio and video data transmission lines.‍
