I had a similar issue once with my old B&W and one of those weird
semi-fixed frequency Sun monitors.
I would try the following:
1) Zap the PRAM about four or five times in a row
2) Perform a safe boot (Hold shift when powering on)
3) If this mode works and you are able to log into the system, check
your display settings
4) Adjust as needed, attempt a normal boot
