When connected via an analog connection, an LCD is vulnerable to the same distortions that affect CRT monitors. However, when connected via a digital connection, DVI, no digital-to-analog conversion is required, and there should be no loss or corruption of the signal. As a result, when running at its native resolution, an LCD should give you a cleaner and crisper image than you'd see on a CRT.
However, the advantage of digital signals for LCDs is of somewhat less importance now than it was a few years ago. Analog signal processing has improved to the point where major differences in image quality can be difficult to detect.

Which is why we get threads like this. Circle of life and all

One other point is that once HDDVD/Blueray becomes common and there are discs out there requiring HDCP, you'll need a digital connection such as DVI or HDMI to play them at full quality.

It also allows the driver software to control more of the screens controls.

That's reminded me of something actually.
Before nVidia moved to the 90-series drivers I was able to fiddle with my TFT settings through the "direct access" bit, like you say.
Now they've moved to the (imo much worse) control panel system I can't find that anymore. Where's it gone?
