DVI Cabling Explained

There are three types of standards you will see in DVI cables as well as many types of cross over adapter cables. It's important to know how each works and which ones are needed for what you want.

• DVI-I - DVI Integrated (Digital and Analog in One Format)
  
  DVI-I is the most popularly used DVI connection. Any video card out there that does support DVI will more often than not have a DVI-I connection on it. It supports both analog signals and digital signals in one cable. It means that if you have a DVI-I port on your video card your fine hooking up most DVI-D or DVI-A devices without needing a separate adapter. Click Here for a DVI-I Cable

• DVI-D - DVI Digital (True Digital)
  
  DVI-D is a direct digital connection between your video card and your monitor. This type of connection provides a fast transfer rate, high quality image and no quality loss due to the fact that all signals from PC's are purely digital; no digital-analog-digital conversion is needed. Unfortunately, due to the lack in conformity by the monitor and video card industry, this standard is not usually seen in either piece of hardware.

• DVI-A - DVI Analog (High-Resolution Analog)
  
  This format is used to carry a DVI signal to an analog display. This format is also used to carry a DVI signal to some HDTV's. Some image quality is lost of course due to the conversion process, but the format transmits a picture of higher quality than standard VGA formats. Tthis format is virtually obsolete. We have seen cables for this standard, but no equipment that actually supports it. Click Here for a DVI-A to VGA Cable

Note: None of these cables can be interchanged with other cables. A DVI-D cable cannot be placed on an analog system nor can a DVI-A cable be placed on a digital system. The standards can not be mixed. A DVI-I port however can accept another DVI-I, DVI-D or DVI-A cable
