CHAPTER 2: Introduction
With the 262K Color LCD Panel,
you can project computer video
on a screen big enough for a whole
room to watch. It’s perfect for
business meetings, conferences,
and classroom instruction.
Your LCD Panel has a range of
262,144 colors, for rich true-color
images. It’s compatible with both
Apple®Macintosh®and IBM
®
compatible computers; on the IBM
compatibles, it will work with VGA—
or with CGA, EGA, or Hercules
®
compatible video, with the optional
DB9 Y cable.
The Y cable that comes with the
LCD Panel lets you attach both the
Panel and your computer monitor
at once, so you can display your
presentation on both
simultaneously.
What’s in the Package
Besides this manual, the package
should contain these items:
• 262K Color LCD Panel
• DB15HD Y cable for VGA
• DB15 Y cable for Mac
®
• Power adapter with cord
• Remote control
• Two AA batteries (for the
remote control)
If anything on this list is missing,
call Black Box right away.
2. Introduction

262K COLOR LCD PANEL
When you connect the LCD Panel
to a PC, it works the same way a
monitor does, taking signals from
the same video port on your PC.
If you have a portable or notebook
computer with an internal screen,
you may have to activate the external
video port before it will work. See
the manual for your computer.
3.1 Setting Up
1. Position your overhead
projector at the right level and
distance for projection. For
best results, you’ll want:
• A high-intensity overhead
projector—for instance, a
400-watt halogen or metalvapor type—that projects a
bright, uniformly illuminated
image. (A rating of 4000
lumens or better is
recommended.)
• A dimmed room with no
direct sunlight shining in.
The LCD Panel works with all
transmissive overhead
projectors—projectors with a
light source that shines through
the image (the kind of
projector you ordinarily use
with transparencies, not
opaque sheets of paper).
2. Make sure everything is turned
off—the computer, the
overhead projector, the
monitor, and the LCD panel.
3. Set up your computer and
monitor near the projector—
close enough for the 15-foot
(4.6-m) Y cable to reach
without stretching.
4. Place the LCD Panel on the
projector’s glass plate with the
controls on the Panel toward
the screen.
3. Installation
Connectors and Switch on the LCD Panel.
