Changing the Output Resolution and Refresh Rate

In addition to the 

the output resolution and refresh rate include resetting the output rate using the front 
panel

 button (see 

 beginning on page 54, and the Windows-based 

Control Program (see the program help file).

Custom Rates — DSC 3G-HD A Only

In addition to the 42 factory output resolutions, 3 custom user-defined rates are available 
for the DSC 3G-HD A via SIS commands (see the 

on page 54 for the command format) or the Windows-based Control Program (see the 
program help file). When no custom EDIDs are defined, these three resolutions and rates 
default to 720p @ 60 Hz. The OSD dynamically updates itself based on the current file 
stored in the custom EDID slot. For example, if a custom 720p EDID has been uploaded, 
the OSD would read 

C1:

 

720P

 

@

 

60

 

Hz

. 

Importing an HDMI EDID — DSC 3G-HD A Only

You can also import the EDID of a connected HDMI sink to use as a custom rate. This 
EDID can be saved and stored in one of three custom EDID slots, which are then available 
for custom EDID emulation or custom output rate generation (custom rate based on the 
EDIDs preferred timings) (see the 

NOTE:  If an imported or custom rate is not a valid output resolution, the output 

reverts to the default (720p @ 60 Hz).

Changing the Output Resolution from the Front Panel — DSC HD-3G A Only

Depending on which Output LED is lit (2.97 Gbps for 3G-SDI, 1.485 Gbps for HD-SDI, 
or 270 Mbps for SD-SDI) you can press a combination of front panel buttons to cycle 
through the different levels of output signal format and change the resolution. This is 
helpful if you are not able to display an image on the screen.
To change the resolution using the front panel buttons:

With the scaler powered on, press and hold the Menu and Auto-Image () buttons 
until the 1.485 Gbps (HD-SDI) LED lights approximately 5 seconds), indicating that 
the unit is now outputting 720p @ 59.94 Hz. If a screen is connected, the following
