Appendix C: Detailed Setup Information
C-1. Setting Representation, Resolution, Colors
Most computers do not just support one single screen mode but rather a series of different modes which
differ in type of representation (text or full graphic), resolution (number of pixels) and number of colors.
Pre-stored standard mode settings for a variety of IBM compatible and Apple Macintosh computers help
the projector to recognize the current mode and adjust for optimum performance automatically.
Apart from this you can enter and save additional modes with any parameters by means of the menu
system. An upper limit is given by the maximum admissible pixel rate (Appendix A-1).
Adjust the projector to optimum display quality, as described below, by using the menu control (see
section 4-4). All steps described can be carried out via the keyboard or the remote control:
1. Adjust the background as necessary to obtain a display with the highest possible contrast. For use
under Microsoft Windows it is recommended that you close all applications first, and by using the
system control, adjust the desktop background to an even black-and-white raster.

Glossary
Glossary of Terms
Amorphous Silicon
See Thin-Film Transistor.
Composite video
A video signal that combines all color and timing components of the picture in a single input line. The
U.S. standard is NTSC. European standards are PAL and SECAM.
Hz, KHz, MHz (Hertz, Kilohertz, Megahertz)
Hertz is a unit of measurement used to express the frequency, in cycles per second, of an electrical signal
or event. (Kilohertz = 1000, Megahertz = 1 million cycles per second).
Keystone correction
Keystoning (distorted image) is caused when the path of the projector light beam is not perpendicular to
the screen. Projectors normally project the image with an angle (e.g. 16°) on the screen. The optical
system can be designed for distortion free projection at this angle (keystone correction).
Lumens
A measure of light output on a screen or other surface. One lumen is the light of one candle power on
each square foot of a surface of a sphere at a radius of one foot from the light source.
Metal halide lamp
A metal halide lamp is a modified mercury arc lamp that is extremely bright. It is filled with a gas with
elements known as “halogens”. The properties of this fill gas allows the lamp to burn longer and
brighter than ordinary incandescent lamps.
NTSC (National Television Systems Committee)
Standard for television signals and other video equipment signals. Uses interlaced scans and 525
horizontal lines per frame at a rate of 30 frames per second.
PAL (Phase Alternate Line)
The format for color television signals used in England, Germany, the Netherlands, and several other
countries. PAL is an interlaced format with 25 frames per second and 625 lines per screen.
Pixel
Short for “picture element.” Unique position on a display that consists of a single dot or group of three
dots (red, green & blue). Total pixels are usually expressed in horizontal x vertical dimensions (e.g. 640
x 480).
Power ON/OFF switch
The power ON/OFF switch is used to turn the machine on and off. The power switch is located on the
back of the projector in the lower left-hand corner.
Refresh rate
The number of times the screen image is “painted” or refreshed per second, expressed in Hz.
28 3M Multimedia Projector MP8620 3M 1997
Remote control sensor
The remote control sensor is located on the front of the projector. It receives signals from the remote
control transmitter (direct line-of-site or bounced off of the projection screen) which control the
different operating functions of the projector. See remote control transmitter.
Remote control transmitter
Allows remote operation of the projector functions by aiming the transmitter directly at the sensor
(maximum range) on the front of the projector or aiming the transmitter at the projection screen so the
signal will bounce off the screen and back to the sensor. The remote also has mouse emulation
capability that will also control the mouse functions of the computer input source.
Resolution
The number of pixels available in a display device for creating images. Expressed as a number of
columns by number of rows (e.g. VGA resolution, 640 x 480 or 720 x 400).
S-Video
A video signal that separates luminance (Y) and chrominance (C) signals. Also known as Y/C video.
SECAM (Séquentiel Couleur à Mémoire)
The color television standard developed in France and used in certain other countries.
SYNC
The timing of the computer's video signal. Usually a PC uses two separate lines for horizontal
synchronization (beginning of the line) and vertical synchronization (beginning of the frame). This
scheme is called
separate sync
If the two synchronization signals are transmitted on a single extra line, this is called
.
composite sync
. If
the composite sync signal is transmitted together with a video signal (usually the green video signal), this
is called
sync on green
. The projector can be set to handle all three kinds if synchronization schemes.
Thin-Film Transistor (TFT)
A tiny (less than fifty microns across) nearly-transparent wafer of semiconduction silicon. These act as
extremely precise electronic switching mechanisms.
VGA (Video Graphics Array)
This is a standard analog interface for PC computers. The resolution for text mode is 720 x 400 and for
graphics mode 640 x 480.
Video
The capability to project images from a VCR, Laser Disc, or PC with CD-ROM Drive is a standard
analog interface for PC computers. The resolution for text mode is 720 x 400 and for graphics mode 640
x 480.
