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 EdidData test image shows a monitor's EDID information.

The bottom line of the GenOps test image shows the name of the format knob list currently in use. The factory default format knob list is named fmt.
