Cross Hatch - Used during manufacture to align the DMDs this pattern can be use-
ful in the field for overlaying the images in multiple projector stacks.
Grey Bars- Provides a grey scale for adjusting the projector colour balance away
from that set during manufacture for applications where a custom balance is
required.
Black Raster- Used as the off measurement for calculating the on/off contrast
ratio.
Grey Raster- Gives an indication of the on screen luminance level that can be
expected when displaying...

The projectors arc lamp emits a luminous fluxmeasured in lumens. This flux is
directed at the screen and illuminates it, the illuminance(E) can be measured in Lux
(lumens/m2) or Foot Candles (lumens/ft
2). The illuminanceof the screen is 
calculated by dividing the incident flux by the illuminated screen area.
The brightness of the screen, known as the screen luminance(B) is determined by
the amount of light reflected from it (or transmitted through it if using a rear 
projection screen). If the screen...

A DMD™ (Digital Micromirror Device™) is a true digital light modulator and
utilises 786,432 (gv) or 1,310,720 (sx) moving aluminium mirrors, with each one
representing a pixel in the final projected image. Each mirror is suspended over
address electrodes by a torsion hinge between two posts. Depending on the voltage
polarity applied, each mirror will either tilt to left or to the right. When light is
applied to the complete DMD™, only the light redirected from a mirror tilting to
the left is projected....

The mirrors in the DMD™ are arranged in a 1024 x 768 (gv) or 1280 x 1024 (sx)
array allowing images of all aspect ratios to be displayed. However, the proportion
of DMD™ effectively used will differ depending on the aspect ratio of the image
e.g. a 5 x 4 aspect ratio on a 5100gv would only require the use of 960 x 768 mir-
rors. The diagrams below show the DMD™ usage for each aspect ratio (4 x 3, 5 x 4,
8 x 5, 14 x 9 and 16 x 9) with the shaded areas representing redundant mirrors.

Up to three HIGHlite Displays projectors can be stacked without any additional 
framing (gravity stacking). One unit can be stacked on top of the other up to three
units. Make sure that each foot is securely seated on the stacking pad.
Connection Instructions
To connect multiple projectors use the supplied DVI-D cable to connect the RGB 
DIGITAL output (INPUT 9) of the master projector to the RGB DIGITAL input of
the slave projector (the second and third stack) until all the projectors are connected....

Next, using a commercially available, bi-directional RS-232C cable connect the
OPTION OUT terminal of the master projector to the OPTION IN terminal of the
slave projector(s) until all the projectors are connected.
OPTICAL AND MECHANICAL ADJUSTMENT
Place the projectors at the proper height for best screen to projector relationship and
ensure that all projectors have the same display orientation. Next, turn on all the
projectors and display the internal crosshatch test pattern using a different single...

Setting up for Double or Triple Stacking
Adjust the lens shift, zoom and focus to clearly display all projected patterns.
If the vertical alignment of the projector(s) is incorrect, adjust the height of the
feet. If there is any keystone distortion, use Keystone adjustment to correct and
save the settings on each projector.
SIGNAL DATA PREPARATION
When stacking multiple projectors each projector should be configured to display
the input image in exactly the same manner. This requires configuring the...
