DVI Cables
DVI Cables: DVI is a standard video interface covering the transmission of video between a source device (such as a personal computer) and a display device. Today many laptops and even the most contemporary retail desktop PCs and LCD monitors feature a DVI interface, and many other devices (such as projectors and consumer televisions) support DVI indirectly through HDMI, another video interface standard. Therefore DVI cables are something which has always been necessary for visuals and videos. OutletPC offers a good range of high quality DVI cables and adaptors including LD (C0265, C0273), GoldX GXDV-AV-06 and Syba C8129. | |||||||||||
| Why Buy a DVI Cable?
DVI Video Cables (DVI stands for Digital Video Interface) is a computer to monitor video connectivity technology commonly used to transmit video from a desktop computer to an LCD monitor. The DVI video cable standard is very easy way to connect a computer to a monitor and offers enhanced image quality and simple Plug & Play installation. DVI video cables are unique because they exist in both analog and digital video cable formats. Which DVI Video Cable do I Need? DVI video cables, for linking PCs to displays, can be confusing since there are three separate types of cables, DVI-A, DVI-D, and DVI-I, which stand for Analog, Digital, and Integrated respectively. Analog DVI (DVI-A) video cables are only equipped to deal with analog signals which come from older desktop to monitor video sources such as VGA. Digital DVI-D video cables accept video from HDMI, DisplayPort, and other computer to monitor digital sources. The best DVI video cable to buy is DVI-I which are DVI Integrated video cables that can carry both Analog and Digital signals, making them compatible with many monitors and computers. How Much Should I Pay for a DVI Video Cable We sell our desktop-to-display DVI video cables for between .60 and .70 cents-per-foot of cable. Some name-brand companies put very high markups on their DVI video cables and claim that their DVI video cables can outperform "lesser" computer to monitor cables. This is not always true. Analog DVI video cable signals have some potential to degrade slightly over a certain distance. DVI-digital video cables however, have no potential to degrade over distance so more expensive DVI video cables are not any better at transmitting video between a monitor and a desktop than cheap DVI video cables. What is the difference between Single-Link DVI and Dual-Link DVI? A Single-Link (also known as a Single Data-Link) DVI video cables uses a single transmitter to send information across computer and monitor. A Dual-Link (or Dual Data-Link) DVI video cable uses two transmitters and can relay a great deal more information and data across the wire (almost twice as much). This increase in data manifests as improved image quality, signal strength, and greater resolution support. Physically a Dual-Link DVI video cable will contain many more pins than a Single-Link cable so it is important to check for device compatibility before determining which cable is the correct one. How does a DVI to VGA / SVGA conversion work? The simple conversion from a DVI video cable to an analog VGA cable (either DVI-A or DVI-I) involves mapping the analog portion of the signal to the analog VGA interface. This process is done relatively inexpensively and adapters and/or cables are readily available for that purpose. Mapping DVI-D to VGA (DVI-Digital to Analog VGA) is much more difficult, more costly, and requires a DAC converter. The difficulty of converting DVI-D video cables to an analog source is the main reason why a DVI-I video cable is the best choice, since it's able to do both. | |||||||||||
