Also, I admit I don't know how to use or where the black point is.
By this I presume you are looking for the black point "control button".
It is not your fault if you do not find it, it is simply because there is no
such control on most LCD displays.
Here are two indirect methods to change the contrast (please do not laugh!):
You can increase the brightness and this will increase the contrast, up to a
point..
You can increase the ambient light (your room light) to decrease the
contrast.
I know that both suggestions are not practical, but only show how much
"progress" the display technology has made in the last years, or, more to
the point, how small the market for professional color displays is
considered to be by the display vendors.

I must admit, I don't know what contrast ratio I want. I have learned
monitors with contrast ratios in the 1:400 and lower are meant for
professional imaging.

I need to understand something regarding LCDs that have ratios over

So, what recommendations does the list members have for my cd/m2?
What contrast ratio do you want? Ideally its something real close to
the
output (print), so these high ratio's are not ideal! One could argue
you'd
be hard pressed to find a print with a white and black (Dmax) that
produces
a contrast ratio of 500:1 if that.
Divide the white luminance by the black point in order to figure out
the
contrast ratio. If you had 150cd/m2 luminance and a black point of .25,
that
would be a 600:1 contrast ratio.
