UltraSharp is merely a marketing term they apply to what they consider
to be the best Dell branded panels. You were wise to look at the specs.
Although, well, you know ;-)
IIRC, TFT active matrix LCD flat panels have a fixed number of pixels
and the native resolution reveals that arrangement. For example, the
1905fp has a native resolution of 1280 x 1024, so the display consists
of 1280 x 1024 pixels. Each pixel is made up of red, green, and blue
subpixel elements arranged horizontally,. I believe that when you see a
"dot pitch" or "pixel pitch" measurement for an LCD monitor, it normally
equates to the distance between the centerlines of same colored subpixel
elements in horizontally adjacent pixels. Or IOW, the distance between
the centerlines of the Rs in "RGB RGB RGB". I don't know whether
some LCD manufacturers and/or resellers use another dimension. But if
you also know the actual display area dimensions, you can crunch some
numbers and see how close they are. For example:
1280 x .294 mm = 376.32 mm = 14.8157"
1280 x .255 mm = 326.40 mm = 12.8504"
If you come across a 19" LCD flat panel with a 14.8" wide display
area advertised as having .255 mm, I'd dig deeper ;-)
A lower dot or pixel pitch number is better in the sense that it can
produce sharper images. But there is more to LCD display quality
and customer satisfaction than just that. I'd say let it ship and take it
for a spin and see if you like it. If you don't, maybe a friend or
family member would take it off your hands.
