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 congured 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.
