No digital video output from XVR-300 in Ultra-45

Question

I am switching from solaris 10/x86 to sparc. I have a new Ultra-45 with XVR-300 graphics adapter. It's running Solaris 10u4. The system was ordered as a standard configuration from the catalog.
The XVR-300 graphics adapter currently produces no digital output. My Sun A1240P0 24" monitor reports no signal on the DVI input. That is, there is no digital output at power on (boot ROM), during Solaris boot (terminal), nor after Solaris finishes booting (X).
The graphics adaptor uses a connector with two video outputs, and comes with a splitter cable with two DVI output connectors. I get no video output on either. The DVI cable I am using is the one that works when connected to the graphics adaptor on the old system.
I added a VGA adapter plug to connector 1 of the splitter cable, and was able to get an analog signal to drive the display via the VGA input connector.
The manuals for the Ultra-45 and for the XVR-300 make no mention of analog vs digital output. They both just say to connect the adapter to the monitor.
Since I can get analog output from the SVR-300, the card is basically working. The DVI cable and the monitor's DVI input work with another system. The only variables are the digital output from the XVR-300 and the splitter cable. (The splitter cable's analog signals work.)
How can I activate digital output and make it the default?

To Set the Sun XVR-300 Graphics Accelerator as the Default Monitor Console Display
1. At the ok prompt, type:
ok show-displays
The following shows how to set the console device:
a) /pci@1f,700000/SUNW,XVR-300@0
b) /pci@1e,600000/pci@0/pci@8/SUNW,XVR-300@0
q) NO SELECTION
Enter Selection, q to quit:
2. Select the graphics accelerator you want to be the default console display.
In this example, you would select b for the Sun XVR-300 graphics accelerator.
Enter Selection, q to quit: b
/pci@1e,600000/pci@0/pci@8/SUNW,XVR-300@0 has been selected.
Type ^Y ( Control-Y ) to insert it in the command line.
e.g. ok nvalias mydev ^Y
     for creating devalias mydev for
/pci@1e,600000/SUNW,XVR-300@5
3. Create an alias name for the Sun XVR-300 graphics accelerator device.
This example shows mydev as the alias device name.
ok nvalias mydev
Press Control-Y, then Return.
4. Set the device you selected to be the console device.
ok setenv output-device mydev
5. Store the alias name that you have created.
ok setenv use-nvramrc? true
6. Reset the output-device environment:
ok reset-all
7. Connect your monitor cable to the Sun XVR-300 graphics accelerator on your system back panel.
Man Pages
The Sun XVR-300 graphics accelerator man pages describe how you can query and set frame buffer attributes such as screen resolutions and visual configurations.
Use the fbconfig(1M) man page for configuring all Sun graphics accelerators.
SUNWnfb_config(1M) contains Sun XVR-300 device-specific configuration information. To get a list of all graphics devices on your system, type:
host% fbconfig -list
This example shows a list of graphics devices displayed:
