98 - Terminology
By strengthening or weakening the tone of the colors, it is possible to project char-
acters and pictures more clearly and attain a softer tint. This is known as contrast
adjustment.
Refers to the simultaneous duplicate projection of images with the use of multiple
projectors in order to increase projection image brightness.
A theft-proof cable (available on the open market) is passed through the holes on
the projector case to secure it to a desk or column. These holes support the Micro-
Saver Security System manufactuered by Kensington Inc.
Outputs computer signals at a pre-determined frequency. The image will not be
projected clearly unless this frequency is aligned with the frequency of the projec-
tor. Aligning the signal phasing is known as synchronization. Projected images
will be subject to distrubance, blurring and horizontal noise if not synchronized.
