I have a Sun Ultra 30 and a monitor which is supposed to work with this
but I get an "Out of range" error from the monitor.

fH: 81.3kHz too high
fV: 76.1Hz

This appears even when doing Stop-A to get to the OpenBoot prompt!

What can I do to fix this as the supplier said the monitor should work with
an Ultra 30!

you should power down the monitor ,then telnet into the server from 
another computer. Then do
#fbconfig -prconf
to find out what the current configuration of your hardware is. Check to 
make sure that the frame buffer has an output mode which is compatible 
with the monitor. You can then use the fbconfig command to set the frame 
buffer output to one usable to the monitor.
#fbconfig -res "what you want to set it too (resoultion,bit 
depth,refresh rate , etc)"
See the fbconfig man pages-
#man fbconfig

The resolution at the OpenBoot prompt is a different matter...
