I have four of these, I think, hooked directly to E3500s & 420Rs, and
through UltraSpec's USB-to-serial keyboard adapters and Sun 13W3-to-VGA
adapters. (Hey, you work with what you have.) Is that close enough?

Sometime I have to fiddle with the video that a given _display_ will
take, but the VKM has never been an issue before. My hunch is that the
newer card and a relatively current monitor are having trouble
negotiating a sync rate they both support because of the presence of the
adapter and the older KVM. (Is this crazy?)
I have one such combination where I just use an rc script to force
the resolution & refresh at boot time.

This happens to me, too, with LCDs in the chain. Like I said, force
the resolution and you should be in tall cotton.

And I don't think there _is_ a manual, but I could dig on Thursday.
