Nick,

Do you have the PC to monitor cable that would have come with the
monitor. If you do you can purchase a simple adaptor that will convert
Mac DB15 to PC monitor connector and then throught the existing cable
onto the monitor.

I recently picked up an adaptor to just this job, costs around �18. The
particular adaptor I chose allows you to set the resolution handshaking
for the monitor and also set where the sync's go to via a set of DIP
switches. The adaptor can work with fifteen resoulations with six
difference sync options.

If the monitor is up to it you can drive it as a multi-sync monitor
controlled from the 'Monitors and Sound' control panel.
