In addition to the
resolution and refresh rate include resetting the output rate using the front panel
(see "Resetting the Output Rate," below), SIS commands (see the

Custom Rates
In addition to the factory output resolutions, three custom user-defined rates are available.

you can capture the EDID of the device connected to the HDMI output or upload a custom
EDID file from a computer (see the
(see the DSC 401 and DSC 401 A Help File). When no custom EDIDs are defined, these
three custom slots default to 1080p @ 60 Hz.
The OSD dynamically updates based on the current file stored in the custom EDID
slot. For example, if a custom 720p EDID has been uploaded, the OSD would display
C1: 1280x720 @ 60 Hz (see
