How To Optimize The DOS-Mode  
Plug And Play  
Plug & Play DDC2B Feature  
This  monitor  is  equipped  with  VESA  DDC2B  capabiliti es  according  to  the  VESA  DDC  STANDARD.  It  allows  th e 
monitor to inform the host system of its identity a nd, depending on the level of DDC used, communicate  additional 
information about its display capabilities.     
The DDC2B is a bi-directional data channel based on  the I²C protocol. The host can request EDID information over 
the DDC2B channel.   
This  monitor  will  appear  to  be  non-functional  if  th ere  is  no  video  input  signal.  In  order  for  this  monitor  to 
operate properly, there must be a video input signa l. 
  
This  monitor  meets  the  Green  monitor  standards  as  s et  by  the  Video  Electronics  Standards  Association  (VESA) 
and/or  the  United  States  Environmental  Protection  A gency  (EPA)  and  The  Swedish  Confederation  Employees  
(NUTEK). This feature is designed to conserve elect rical energy by reducing power consumption  when the re is no 
video-input  signal  present.  When  there  is  no  video  input  signals  this  monitor,  following  a  time-out  period,  will 
automatically switch to an OFF mode. This reduces t he monitors internal power supply consumption. After the video 
input signal is restored, full power is restored an d the display is automatically redrawn. The appeara nce is similar to 
a Screen Saver feature except the display is comp letely off. Pressing a key on the keyboard, or clicking the mouse 
restores the display.
