By the way, which technology type are you choosing?

I'd expect it to be Wide Gamut CCFL, unless you have better information.
Also, is this the only screen you have connected to your computer?
Also, do you have any other computers in the house you can try calibrating, to make sure the calibrator itself isn't faulty?
