Hue, saturation, and brightness are the three qualities which
constitute what we normally refer to as “color”.
Hue
, often used as a synonym for “color”, is the quality
that distinguishes among red, green, yellow, and so on.
Saturation
is the amount of color present that distinguishes
pale or washed-out colors from vivid ones.
Brightness
is related to the amount of light emitted by your
display or reflected from an object. This quality enables
you to describe an object as “bright” or “dim”.
Hue is generally not adjusted. Depending on the TV, however, it
may be necessary or desirable to adjust the hue to approximate
the monitor’s display.
Anti-Flicker
reduces the amount of display flicker. Display
flicker is both a distraction and tiring to your eyes, and is most
pronounced when text is being displayed.
Dot Crawl
is an undesirable characteristic of many Composite
televisions that is seen as thin, jagged edges moving around
objects on the screen. The “Frozen” setting freezes, or
eliminates, the dot crawl, and is especially useful for viewing
pictures or stills. S-video equipment does not exhibit this effect.
