First and foremost, the first thing i noticed when i got my first
LCD was that the dynamic color range bites really bad when compared
to a CRT. A CRT, by it's basic design, has the ability to create an
infinite number of colors and shades of those colors while the LCD
is limited by some other dimension like how dark an LCD pixel, at its
best, can go. A CRT 'pixel', can go almost perfectly black while
an LCD pixel always has a small bias of light to it. What this means
is that pictures that are relatively dark have a very limited dynamic
color resolution, although pictures that are relatively 'normal' or light
seem to display ok.
It seems that if they would incorporate a backlight dimmer this
problem could be adjusted, at least to some degree.
