Thinking hard now.... I have to calibrate my own monitors so that they match the printer - a thoroughly miserable task - trust me...
Check that your monitor is running an appropriate screen profile. If your monitor is fairly recent, go to the manufacturer website and look for colour management and profiles. Any of these should improve what sounds fairly extreme, but I use an SRGB profile. If you see this one and it still looks odd, then we have at least narrowed it down. Keep positive - this, is progress :-)
If this confuses you at all, then PM me with monitor and vid card details and I will try to find them for you.
