User assigned EDID Mode — Using SIS commands, an EDID file can be selected from a
table of 19 EDID files. One additional EDID file location is reserved for user-loaded EDID files
for the VGA and DVI groups. Once a user assigned EDID is chosen, the switcher stores it at
the inputs and no longer polls for the EDID of a connected display. The chart below lists the
native resolution of each factory EDID file and timing characteristics associated with each.

If the display connected to the VGA output of the switcher does not support DDC, or the
switcher does not obtain EDID from the output, the default resolution (2) is used.
HDCP
The DVI and HDMI groups are HDCP compliant. When EDID Minder is enabled, (default),
HDCP is not supported on the DVI inputs.
HDCP communication occurs between the selected input source and the output device
directly (pass-though).
