EDID MANAGEMENT
EDID Modes
1. EXTERNAL MODE:
In order to use the external (display) EDID, the DVI to VGA Converter must
be powered after it has been connected to the display. If the Converter is
powered before it is connected to the display, then the internal EDID will be
used.
2. INTERNAL MODE:
The internal EDID is a preset EDID that is stored in the DVI to VGA
Converter. This pre-programmed standard EDID data structure is compatible
with most A/V displays. All resolutions and audio formats specified in
the internal EDID will be passed to the source device. See page 8 for a
complete listing of the resolutions and audio formats listed in the internal
EDID.
