(since this is the second time today this question comes up, I'm CC-ing the
other poster too)

Wrong. You can change the default resolution at the open boot prompt, as
documented at
(search for output-device on that page). According to that page, 1152 x 900 at
76 Hz is the default resolution.

On that same page, there are also user contributions about which monitors do and
which don't work. It is meant for a Sun Blade 100, but the on board video card
in those machines is very similar to the one in an ultra 5 / 10, so it could be
useful for those machines as well. (Search for SyncMaster on that page to see
the reports.) Note that some (all?) the resolutions mentioned in there are for
Solaris X server (XSun), which can be changed by the solaris program

BTW: perhaps the 13W3 connector can be used to connect an old 13W3 sun monitor
to a standard vga card? (Or at least to a sun framebuffer with vga connector,
which is what I use in my setup.)

Hope this helps
