Why does detect displays screw up my picture?

I am trying to get 1920 x 1080 working with my Mac mini. It was working fine until a recent restart now it is not available, leaving me with 1280 x 768. I tried hitting the "Detect Displays" button but then my screen just goes black.

Thanks Doc. I still can't get the resolution I want and had before but at least the detect displays button no longer screws up my screen.
