Brightness Uniformity — SUBMENU 
Brightness Uniformity provides further refinement of displays already matched for 
their primary colors and overall light output. Use Brightness Uniformity to create an 
exceptionally smooth image in which no area appears brighter and/or more red, green 
or blue than another. In the Brightness Uniformity menu, enable the “Uniformity 
Enable” checkbox (enter a checkmark) to access a multitude of adjustments for

• Color Adjustments by X,Y
 — Enter known x/y coordinates from the 
chromaticity graph. For best results, use with a color meter. 
• Color Saturation
 — Adjust color slidebars and judge image color by eye. A 
color meter can also be used.  
A user-defined color “adjustment” can be applied by selecting it in the Advanced

NOTES: 1) Adjust offset before gain, since offset affects gain. 2) A value of 128 
represents no change in normal odd pixel offset or gain. 3) Odd Pixel Adjustment 
eliminates “1 pixel on, 1 pixel off” patterns only, not any type of larger patterns.

Whenever you install a new lamp in the 
projector, access the Lamp menu to record 
the lamp serial number in the projector’s 
memory. You can also choose a lamp mode 
for regulating power and light output, 
change optical aperture size, and access 
other read-only information pertaining to 
past and present lamps.

“

Do not lower the “

 IMPORTANT  
Always record the serial number of a NEW lamp. 
When a new lamp is installed and its serial 
number recorded by selecting “Change 
Lamp” in the Lamp menu, the lamp timer 
resets to “0” and begins logging time for 
the new lamp. This tally appears in both 
the Lamp menu (see right) and the Status 
menu. 
To review the number of hours logged for 
previous lamps, consult the Lamp History 
menu.

A single Mirage projector can display 3D (stereographic) images as described below. 
Such images require a specialized source, as well as additional hardware and software 
in order to be displayed and interpreted correctly in a typical 3D active stereo viewing 
environment. 
In simple terms, images generated from a 3D-video source consist of a series of 
images (frames or fields) that alternate quickly between two slightly different 
viewpoints...
