Digital Vibrance
Note:
The
Digital Vibrance Control
(DVC)
feature supported by the GeForce2 MX
and newer series of NVIDIA GPUs.
DVC
, a mechanism for controlling color separation and intensity, boosts the color
saturation of an image so that all images
including 2D, 3D, and video
appear
brighter and crisper (even on flat panels) in your applications.
Digital Vibrance can be turned
off
or set to different levels from
low
to
high
as shown
in
Figure 7.1
.
Brightness, Contrast, and Gamma
Note:
The
Color profile
option on this page must be set to
Standard Mode
in order
to use the
Brightness
,
Contrast
, and
Gamma
sliders.
To adjust the
Brightness
,
Contrast
, or
Gamma
values for the selected color channel,
click and move the sliders until you see the desired adjustment.
Notice that the color curve graph changes as you adjust values using these sliders,
which also reflects in the values of the
Input
and
Output
boxes displayed on the left
of the Gamma slider.
Adjusting brightness, contrast, and gamma values helps you compensate for
variations in luminance between a source image and its output on a display. This is
useful when working with image processing applications to help provide more
accurate color reproduction of images (such as photographs) when they are
displayed on your screen.
Also, many 3D-accelerated games may appear too dark to play. Increasing the
brightness and/or gamma value equally across all channels will make these games
appear brighter, making them more playable.
