Creates a new format knob list based
on video format information stored in
the EDID structure of a VESA® DDC
compliant monitor attached to the
VGA or digital video connector. The
generator builds the list by first
selecting VESA standard formats
from generator's built-in library. The
selection is based on the standard
formats bits set in the EDID structure.
If the EDID structure indicates the
monitor has a non-VESA preferred
video format, a new video format is
created based on the preferred format
parameters. The created format's
name starts with the three character
manufacturer's ID code in the EDID
structure and ends with a number
based on the number of active lines
and refresh rate. The format is saved
in user memory and added to the new
knob list.
The newly created knob list is given a
three character name that matches
the manufacture's ID code and the list
is saved in user memory. Any previ-
ously created knob list with the same
name is overwritten with the new list.
The generator will then start using
the newly created format knob list.
If the generator is powered down in
this configuration, it will continue to
use the DDC configured format knob
list on power up.
Pressing the DDC autoconfiguration
button combination while using an
autoconfigured knob list will always
switch to the format knob list named
"fmt" (factory default list). Pressing
the DDC auto-configuration button
combination a second time will trigger
a new DDC autoconfiguration cycle.
NOTES:
The function will report
Error 9491
(DDC Not Available) on the front
panel LCD if valid DDC data can not
be obtained for any reason.
The

monitor's EDID information.
The bottom line of the
GenOps

knob list currently in use. The factory
default format knob list is named
