Changing the Output Resolution and Refresh Rate

In addition to the Output submenus (see pages 25 and 27), other options for setting the output resolution and refresh rate include resetting the output rate using the front panel button (see Resetting the Output Rate on page 37), SIS commands (see the Output Configuration commands 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 Output Scaler Rate SIS commands 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 Output EDID command on page 54).

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:

1.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 message is displayed:

Press Enter to confirm the new resolution. Unit will return to previous resolution in 15 seconds if not confirmed.

2.Press the or button repeatedly to cycle through the output resolutions typically associated with the HD-SDI output format.

NOTE: If you do not press a button within 15 seconds, the DSC reverts to the previous output rate and you must return to step 1 if you want to select another resolution.
