SECTION 15 GLOSSARY
This glossary includes definitions for only a few of the terms used in the S3
Graphics User Manuals. Numerous on-line glossaries are available if the
graphics term you are looking for is not listed below.
Brightness - Visually, brightness reflects the intensity (or luminance) of the
image going from darker to lighter. In S3 ScreenToys Desktop color, brightness
represents the lowering or raising of the gamma curve. Brightness adjustments
cause all values on the gamma curve to move down or up by the same amount.
Contrast - Visually, contrast reflects the ratio between the lightest and darkest
elements in the image going from low contrast to high contrast. In S3
ScreenToys Desktop color, contrast represents the angle of the gamma curve.
Contrast adjustments decrease or increase the angle of the gamma curve while
keeping the (x, y) point on the curve fixed at (0, 0).
CRT – Cathode Ray Tube. Used in reference to an external analog display
device, the CRT has the 15-pin VGA connector as its standard interface.
DualView -- Microsoft’s term for extended desktop mode in Windows. Microsoft's
definition for DualView is available online at

DVI - Digital Video Interface, is a high-speed digital connection for visual data
types that is display technology independent. DVI provides digital and analog
support in a single connector and allows for plug and play through hot plug
detection, EDID and DDC2b. DVI is often used to describe a detachable flat
panel display device.
Gamma -- Gamma is the brightness of a display adapter's output. In practice,
gamma is differentiated from brightness and contrast by the way it affects the
adjusted output. Gamma adjustments do not change the bottom left point and the
top right point of the gamma curve. In the S3 ScreenToys Desktop color, the
Gamma slider allows you to adjust the gamma within a pre-determined range.
The value reported on the slider is relative and does not report an actual gamma
value.
HDMI – High-Definition Multimedia Interface is an uncompressed, all-digital
audio/video interface between any audio/video source, such as a set-top box, PC,
DVD player, or A/V receiver and an audio and/or video monitor, such as a digital
television. HDMI transmits all ATSC DTV standards and supports 8-channel
digital audio.
