Apple Studio Display on XP Problem

Hello, I've recently acquired a 21" Apple Studio Display monitor that is
both huge and awesome. However, I cannot change the geometry settings
with my video card(old GeForce2) software. I downloaded the Display
Tuner program, but the monitor doesn't support DDC-CI, so I can't manage
my settings with it. Obviously, I can't change these settings from a
panel on the monitor itself either.

If someone could direct me to a different program that allows me to
manage the geometry settings of this Apple monitor on my Windows OS, I'd
be truly grateful.

Thanks in advance.
