• If the monitor does not "sync up" at the default console
resolution, it may be necessary to choose a different console
resolution.
A.1.2 EDID Auto-Detect Feature
If you are using a monitor with DDC2B/EDID protocol the default
resolution will be determined using the Auto-Detect feature.
With this protocol, the Raptor 4000/4000e card first checks the
Detailed Timing and Established Timing Identifiers (taking the first
one supported) and then tries to match the Standard Timings.
NOTE: The monitor must be turned ON prior to booting the
system in order for a Raptor 4000/4000e series card to
communicate with it. Some adapters and cables may block this
signal.
If the Auto-Detect feature fails the card will default to
2048x2048@60,analog.
Other methods described in this appendix will override any
information obtained via EDID.
A.2 Output-Device Method
For systems with multiple displays, the output-device variable
provides a method to specify which should be used as the console.
When using a Sparc Ultra 25 or 45, please be aware that there is a
limitation in the number of characters you can assign to the
output-device variable. To avert this limitation, you will need to
use the devalias command to set your Raptor 4000/4000e card
as the console device.
The following steps will set a Raptor 4000/4000e card to display
console video by using the output-device variable. Be sure to
make a note of your configuration prior to changing your settings.
