Do I need a DVI display to properly change screen resolution?

[cadensol]

I have this after installing iPC 10.5.6:

NVIDIA GeForce 8600 GT:

and now, i am running on OS X 10.5.7

but I get a blue screen whenever I've tried to change display resolutions. i've tried nvinject. My display doesn't have a DVI out or am i missing something? Would greatly appreciate any insights you guys might have. Thanks.
