I think you may need to force the display if you can to the 1000x1022
resolution. That doesn't sound too far off what I recall the
are you connecting into the thing thru serial so you can poke around? I
don't recall for sure if the default loaded system allows serial login,
but you might be able to get on thru the serial port and adjust things
as well. I didn't read the guide above, this is from fighting with the
systems long ago.
I used a box that was made by Raritan or such to convert the video and
keyboard to allow connection to VGA KVM and those boxes had some active
circuitry in them to do things with the selects. They weren't doing
anything as far as sync adjustment, but may have pulled a different set
of settings to both the Sun system and to the KVM and on to the
display. I did not have much trouble with that, so don't recall having
to play with the frame buffer settings.
