Right now I have an LCD monitor (Sony Xbrite) hooked up w/analog (new monitor on old system).
In a week or so I will have it hooked up to DVI. Will I see improvements in the text? Not that it's
bad,
it's very crisp, almost too crisp, like it needs some rounding or smoothing. I'm used to reading on
a Sony
200sx (I think "sx").

Whether you'll 'notice' it is as much a function of your perception as it
is the LCD.
The digital interface is all synchronized together. That's it's purpose.
The video 'dots' are sent in concert with a synchronized dot clock so it
tells the LCD "here's the dot for that pixel".
When using analog, though, the LCD monitor is decoding the video like an
analog monitor does. I.E. the synchronization is 'line start' and then a
stream of dots come out. Difference between the two being, while the
electron gun in a CRT can light up whatever phosphors happen to be under it
when the video signal says 'dot here', an LCD has *exactly* the right
number of pixels for the precise resolution it's displaying that must match
the dots being sent, one for one, so whatever the analog video is saying
when it 'scans over' that LCD pixel is how bright it will be. So, if the
analog video and LCD dot scanning are not *exactly* in sync (and there's no
dot clock to make it so), the pixel brightness can be off a bit (pun)
because it's sampled before, or after, it reaches the 'exact' value.
And in the analog world, there is always some jitter, timing error, etc so,
in theory, you lose some of the crispness and contrast ratio with analog on
the LCD since you don't necessarily get samples at the precise peaks and
valleys of the video dots. On the other hand, the analog video is being
generated by a rather precise clock in the video card and if the LCD clock
is rather precise then the error isn't much and maybe you'd never notice it.
That whole scenario is not a problem on a CRT because the 'dot' isn't
sampled; it's always modulating the beam and a dot can land just anywhere
and hit phosphors so the 'dots' are, well, where they are. They don't have
to 'line up' with anything on the tube like they do on an LCD.
I hope that made sense.
