EDID Minder
EDID Minder ensures that the connected source sees the EDID of a display, even if a display
is not connected. Depending on the EDID mode selected (by SIS command), the EDID of a
connected display can be stored automatically, or the user can manually select from the table
of factory loaded EDID les. This EDID is stored on an EEPROM located at the HDMI input.
By default, the HDMI DA2 is congured to store EDID from the display connected to output 1
automatically. The unit reverts to this configuration after a factory reset.
Automatic Mode
In automatic mode, the HDMI DA2 automatically reads and stores EDID from output 1 (a
different output can be chosen using SIS commands). This EDID is retained until a different
display is connected or the unit is power-cycled. If no display is connected when the unit is
powered on, then a factory default EDID (720p @ 60 Hz, 2-Ch audio) is present.
User Assigned Mode
In user assigned mode, the user can select from 46 factory loaded EDID les, each catagorized
by rate type (PC or HDTV), video format (DVI or HDMI), audio type (2-Ch or Multi-Ch), and
native resolution. The unit retains this setting after a power cycle.
Additionally, four user-loaded slots are available to save the EDID of any connected display.
EDIDs saved to these slots are retained after a power cycle. Upon a factory reset, these EDIDs
revert to the factory default (720p @ 60 Hz, 2-Ch audio).
A table showing the factory loaded EDID options is shown on the following page. The EDID
memory location is labelled
X$ for consistency with the value in the SIS commands.
