The Basics of DVI Standard  DVI  is  a  well-known  form  of  video  interface  technology.  It  is  to  maximize  the  quality  of  flat  panel  LCD monitors and modern video  graphics  cards.  Before  they  came  into  the  market,  there  were  short-lived  Plug  &  Display  standards.  But  once  DVI  came  into  the  market,  it  replaced  them.  If  we  see,  most  cards  include one or two  DVI output ports.   

  Apart  from  used  as  the  standard  computer  interface,  the  DVI  standard  was  the  method  for  HDTVs,  movies,  and  DVDs.  But  if  we  look  at  the  current  market,  HDMI  cable  have  taken  place  for  high-definition  media  delivery.  And  DVI  is  more  exclusive  to  the  computer market.

About the DVI Formats?   DVI  cables  are  mostly  for  direct  digital  connections  between  the  source  video  and  LCD  monitors.  It  provides  faster,  high-quality  results.  With  old  video  cards,  digital  video  signal  converts  into  analog  at  the  VGA  output.  Then  the  analog  signal  travels  to  the  monitor  and  reconverts  the  digital  signal.  With  DVI  cables,  it  eliminates  the  analog  conversion.  Hence  the  process  improves  with better connection between source and display.

Here are some of the popular types of DVI cables:  ● DVI-D Cables  These  are  for  direct  digital  connections  between  the  source  video  and  LCD  monitors.  It  provides  faster,  high-quality  images  because  of  the  digital format. All video cards initially produce a digital video  signal.  Then  it  converts  into  analog  at  the  VGA  output.  Then  the  signal  travels  to  the  monitor  and  the  cable  converts  it  to  a  digital  signal.  Overall,  DVI-D  eliminates  the  analog  conversion  process  and improves the connection between source and display.  ●

DVI-A

If you  connect  a  DVI  computer  to  a  VGA  monitor,  it  the  perfect  cable  for  your  use.  They  carry  a  DVI  signal  to  an  analog  display  such  as  CRT  monitor  or  budget  LCD.  The  most  common  application  of  DVI-A  is  connecting  to  a  VGA  device  because  DVI-A  and  VGA  carry  the  same  type  of  signal.  Otherwise,  there  would  be  some loss in the quality of the signal involved.

DVI-I

These cables  are  capable  of  transmitting  either  a  digital-to-digital  signal  or  an  analog-to-analog  signal. This makes it a more versatile  cable, usable for digital as well as analog connections.    Like  any  other  format,  DVI  format  and  analog  formats  are  non-interchangeable.  It  means  that  DVI-D  cable  will  not  work  on  an  analog  system  for  DVI-A  on  a  digital  system.  To  connect  an  analog  source  to  a  digital  display,  you  need  a  VGA  to  DVI-D  electronic  converter.  You  will  need  a  DVI-S  to  VGA  converter  to  connect a digital output to an analog monitor.

The Length Considerations   According  to  the  official  DVI  specifications,  all  DVI  equipment  must  maintain  a  signal  at  5  meters.  However,  many manufacturers  put stronger cards and bigger monitors for maximum length.    When  a  DVI  is  unstable,  you  might  experience  artifacts  and  “sparkling”  pixels.  Eventually,  you  will  lose  the  display.  To  curb  such  situations,  consider  in-house  tests  on  various  equipment.  Using  DVI-I  cables  at  extensive  lengths  may  show  a  digitally-clear  image  on  your  screen.  Because  analog  has  a  longer  run.  VGA  or  HDMI cable​ is the best choice for long runs. 

  Choosing The Right DVI Cable    It  is  critical  to  choose  the  correct  type  of  cable  for  your  products.  Make  sure  to  check  both  of  the  female  DVI  plugs  to  determine  what signals are they compatible with.

● If your one connection is DVI and the other is VGA, DVI is analog-compatible. And you need a DVI to VGA cable or a  DVI/VGA adaptor.  ● If both the connectors are DVI-I, you may use any ​DVI cable​. 

● If one connection is analog and the other is digital then there is no way to connect them with a single cable. You will have  to use an electronic converter box, such as our analog VGA to  digital DVI/HDMI converter. 

 

How To Recognize A DVI Cable   To recognize the cables, the flat pin on one side states whether the  cable is digital or analog.

● A flat pin with four pins is either DVI-I or DVI-A. ● A flat pin alone states DVI-D.    Its  pin  sets  vary  depending  on  whether  the  cable  is  single-link,  dual-link, or analog:  ● Two separated 9-pin sets (rows of 6) for a single-link cable.  ● A solid 24-pin set (rows of 8) for a dual-link cable.  ● A separated 8-pin and 4-pin set is for DVI-A   

Connecting DVI To VGA   It depends on the connectors and displays. 

DVI Source To VGA Monitor​:  1. DVI-I Source:​ You need a DVI to VGA adapter.  2. DVI-D Source:​ You'll need a DVI-D to VGA Video Adapter.

VGA Source To DVI Monitor   Here  either  you'll  need  either  a  VGA  to  HDMI/DVI  converter  or  a  DualHead2Go VGA to Dual DVI/HDMI Converter.
