EDID Minder

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 files. This EDID is stored on an EEPROM located at the HDMI input.

By default, the HDMI DA2 is configured 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 files, 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.
