DPMS – Abbreviation for
➟
VESA Dis-
play Power Management Signaling. This
allows several stages of monitor power
saving mode. The graphics boards de-
scribed in this manual support VESA
DPMS.
쎲
DRAM – Abbreviation for Dynamic Ran-
dom Access Memory. Dynamic random
access memory with direct access.
쎲
EDO-RAM – Abbreviation for Extended
Data Output Random Access Memory (hy-
per page mode). EDO-RAM is especially
advantageous in graphics boards because
the most recently required data remains
held in memory. Image rendering involves
multiple consecutive read access of simi-
lar data, so EDO-RAM results in signifi-
cantly faster speeds.
쎲
FCC – The FCC radiation standard states
that this device has been tested and meets
the requirements for digital class B devic-
es in accordance with section 15 of the
guidelines as provided by the American
Federal Communications Commission
(FCC).
쎲
FIFO method – Abbreviation for first in,
first out: A system used in batch process-
ing and queues, in which the first arriving
signal is processed first.
쎲
Fixed-frequency monitor – A monitor
that can only be operated with at a specif-
ic resolution and refresh rate.

mapping
쎲
Front buffer – Refers to the visible im-
age area in the case of
➟
Double buffer .
쎲
Full-scene anti-aliasing – Describes a
type of
➟
Anti-aliasing that is applied to
a complete frame. Two processes are
used in this form of anti-aliasing: Super
sampling and Accumulated buffers. In the
case of super sampling, a much higher res-
olution is calculated than the one to be
displayed and then reduced. With the ac-
cumulated-buffer process, several views
of a scene are drawn that are then com-
bined to a single image.
쎲
Geometrical transformation – The po-
sition of the objects in space is determined
based on the observer.

Graphics accelerator – ELSA Synergy
2000 is a graphics accelerator board that
is especially well-suited for the user envi-
ronment that requires intense graphics.
쎲
HighColor – Stands for a graphic display
mode with 15 or 16 bit color depth per pix-
el (32,768 or 65,536 colors).
쎲
Horizontal frequency – The monitor
line frequency (horizontal scan frequency)
in kHz. This value must be set according to
the monitor's requirements to prevent the
monitor from being damaged in extreme
cases!
