Frame Buffer
The portion of the memory buffer on the graphics card used to store the
image being displayed. All rendering processes have been accomplished by
this stage and this buffer contains only a one-to-one relationship of the data
to be relayed to the display.
Frames Per Second
In terms of 3D graphics, refers to the rate at which the graphic processor
can render new screens per second. Higher rates equals better, more
naturalistic performance for such things as games set in a 3D environment.
Sometimes abbreviated to “fps.”
Gamma
Sometimes confused with brightness, gamma actually refers to the
correction that is applied to any display device in order to produce more
gradual increases or decreases in the perceived brightness for that device.
A change in gamma produces a non-linear change in the color curve,
ensuring that perceived changes in color and intensity are consistently
applied.
Gouraud Shading
A shading method used to produce a smooth lighting effect across a 3D
object. A specific color is used at each vertex of a triangle or polygon and
interpolated across the entire face.
GPU
GPU is an acronym for “Graphics Processing Unit. The GPU powers the
operations of a graphics card including support for 2D/3D and video.
HDCP
HDCP is an acronym for “High-Bandwidth Digital Copy Protection.” It is
a form of digital rights management designed to protect copyright of
signals being transported across DVI or HDMI™ connections. Several
international regulatory bodies have recommended its incorporation into
high-definition display and playback devices.
