I'm hoping someone can shed light on this. For
the past week, I've
been battling to get my Sun Ultra-60 video switchable through a Belkin
8-port KVM switch. The monitor is a Samsung 214T 20" LCD.

- Connect either of the above to a port on the KVM
switch: Switch
does not recognize that anything is connected and refuses to pull in
the relay (I can hear an audible click from any channel with
recognized video). The status LED on the KVM keeps flashing to say
"no one there!". Obviously no video.
I don't know about your specific KVM, however, the Belkin 8 port one I
have specifically looks for a keyboard port. Even if there is an active
video source, unless I also plug in the KVM into a PS/2 style port on
the computer end, it will refuse to display video.
I'm not sure if it's looking for 5V or something else. You might
experiment with a PS/2 style plug and see if you can provide ground and
+5V on the appropriate pins - that might do the trick.
I've had troubles even using a PS/2<->USB keyboard plug with some
machines (i.e. G4 Macintosh), but there are boxes that simulate an
always connected keyboard and mouse. When connected to those, it always
worked. I don't know if you can still get those anymore - they were
meant for PC servers whose BIOS (or badly written OS) would freak out if
there was no keyboard attached and therefore behaved badly when attached
to KVMs.
