Here are the specs on the Dell 1905fp Ultrasharp:

The contrast ratio is 800:1. The NEC has a 700:1 contrast ratio. For
looking at dental x-rays, contrast ratio is one of the most important
specifications.


I hope your approach to dentistry is more multi-dimensional than your
methodology of evaluating display hardware. The NEC, like many newer LCD
monitors, but unlike the 1905fp uses a transreflective display. If you are
unfamiliar with this type of display versus a conventional LCD display, use
the analogy of a glossy versus a matte finish photographic print. Clearly,
some prefer one over the other, but the higher end of the market, especially
product geared for the graphics enthusiast is gravitating toward the
transreflective type of display. And more to the point, any comparison
between numerical contrast ratios between a standard LCD and a
transreflective LCD is completely meaningless. The transreflective displays
offer a much higher qualitative contrast ratio and much richer color
saturation than a standard LCD, very much like viewing a good quality CRT in
that respect. Their one downside is their reflective characteristic, which
is shared by CRT's, and can be problematic if you have little or no control
of the lighting in your workspace. Don't take my word for it, let your own
eyes decide by doing some eyes-on shopping. Or you could read what these
