Chapter 7 Configuring Key ForceWare Graphics Driver Features Color Correction Settings 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.
