EDID NOTES: EDID Minder is only supported on the VGA and DVI video groups. Attempting to assign an EDID file to the HDMI
or composite video group (
X!
= 3 or 4) will give an error (E13).
In DVI/HDMI input combine mode, the DVI inputs are routed to the HDMI output. The EDID of the HDMI output
is used for the DVI group inputs when DVI/HDMI combine mode is enabled.
For the DVI video group,
X1^
= 12-13 are 256-Byte EDID files, each containing a CEA 861 extension block, with
the listed audio support. For the VGA video group, these EDID files are 128-Byte with no audio support, so they
are repeated for consistency.
