EDID Minder
the DVI and VGA/YUV groups feature EDID Minder, ensuring that each input source reads
the EDID of the output display even when not selected. the result is the video source powers
up properly and reliably outputs content when selected. the EDID remains in the selected
mode (automatic or user assigned) even after loss of power.
the DVI group does not support HDCP by default. In order to support HDCP, EDID Minder
must be disabled. EDID Minder can be disabled for the DVI group using SIS commands.
Automatic Mode — If an output display has not been connected, a default EDID file is
placed on the VGA and DVI inputs according to the following table:
Input Group Default EDID
VGA 1024 x 768 @ 60 Hz
DVI 1024 x 768 @ 60 Hz
Figure 18. Default EDID Resolutions
When a display is connected to the group output, the EDID of that display device is read and
replaces the default EDID on each input. the EDID remains even if the display is removed.
If a different display is connected or a user assigned EDID is selected, the previous EDID is
overwritten.
NOTE: When the HDMI/DVI combine mode is enabled at the same time EDID Minder
is enabled on the DVI inputs, the EDID will be updated with the HDMI output
device EDID.
