(250-0446)                Disabling DDC               Faxback Doc. # 32875

As previously mentioned, DDC offers "Plug and Play" ease of set-up to the
user.  To take advantage of DDC requires suitable hardware and software
inside your computer and it is possible that you will be attaching your
monitor to a computer that does not support DDC.  In most cases, this does
not cause a problem other than the fact that the screen mode will need to
be optimized manually.  However, if you are attaching to a PS/2 computer or
one of a handful of video adapter cards, the DDC may not be compatible with
the computer and results in either a blank screen or a green screen being
displayed.  In such a situation, this sequence should be followed:

Press and hold the left hand side of Key 7 (see page 10) for 15 seconds.
This disables DDC.  DDC can be enabled again by pressing and holding the
right hand side of Key 7 for 15 seconds.

In both cases it is mandatory this is done while something is displayed on
the screen since after the 15 second delay the screen will flash,
confirming that the change has been implemented.

Note that it is possible to find out whether or not DDC is enabled by
powering off the monitor and then powering it on again while looking at the
LED.  If DDC is disabled, the LED will go amber for two seconds at power
up, before turning green.
