You're probably referring to contrast or brightness ratio,
which is a measure of the range of brightness a monitor
can display, from black to white. This translates into a
range of colors, or color gamut, the monitor can resolve.

Because of the backlight technology used on LCD
monitors, the range of colors they can display is more
limited than CRTs, with near blacks and near whites
being the most problematic. CRT manufacturers never
made a habit out of publishing this brightness ratio spec,
because a lack of color gamut wasn't a major issue
until LCDs came along. A Sony Trinitron typically has
a brightness ratio exceeding 750:1, and brighter tubes
such as Mitsubishi's Diamondtron can exceed 800:1.
Meanwhile most LCDs only range from 400:1-450:1,
with a few higher-end models exceeding 600:1.

Some are.

Not really.
