I'm sure there are various guides on the web to choosing a monitor
that would be useful. Any article that explains the different
characteristics of the panel technology is probably a good
lead (ie. look for LCD + IPS + PVA).
The black characteristics of an LCD are pretty much fixed by
the nature of the pixels when they are off (blocking light), and
the backlight. The black level will change as the backlight
level is changed, but one of the things about an LCD is that the
color of the black (the black point) is often slightly different
to the color of the white point (ie. the "off" state of the pixels
is not a neutral filter).
A very few displays have a RGB LED backlights, and these permit
modifying the white point of the display directly, and this will
probably alter the black point as well.
Which are the most critical parameters to take in consideration while
choosing a monitor?
In my opinion:
Black level
Viewing angle
Uniformity
Stability
Dead Pixels
Gamut
and you need to put screen size and cost in there somewhere :-)
There are many other details that will be important for some
people:
Resolution
Brightness
DVI, HDCP
In monitor LUTs > 8 bit
Calibration software & instrument
