 User’s Manual     3-25. 
Use options in the Image 
Settings menu to alter your 
main image without affecting 
its size or position. Changes 
made to the Image Settings 
menu are applied 
immediately and are saved 
when you exit the menu 
(press 
Ex i t or
 Menu). Options 
not available for the projector 
model or source are disabled 
and appear dim (gray).

maintaining good details for blacks. Conversely, if the image is washed out and 
unnatural, with excessive detail in black areas, increase the setting. In high ambient 
light conditions, lower gamma may produce better results than higher gamma. Gamma 
of 2.5 (default) indicates the gamma table has not been adjusted. For more 
information, refer to Advanced Image Settings, Gamma Table submenu. Again, good 
gamma improves contrast while maintaining good...

For these signals, change the Color Space to RGB, then define a new channel for 
future use.

INPUT VIDEO BLACK: This control 
compensates for incoming elevated black 
levels present in certain video signals, and 
ensures that blacks in the display are 
neither crushed (i.e., where dark grays appear black) nor excessively elevated (i.e., 
where blacks appear dark gray). By default, the projector automatically determines the 
best setting according to the type of incoming video signal:

monitoring image content and adjusting the controls appropriately—further 
adjustment is typically not required to obtain proper blacks or whites. NOTE: This 
automatic adjustment requires at least 6-12 consecutive white pixels in the image. 
Without these pixels, input levels may produce skewed colors, particularly in non-
video images. 
However, for a very unusual source exhibiting one or more overly high blacklevels 
(typically caused by a noisy...

AUTO COLOR ENABLE – When a checkmark is present, selecting a specific blacklevel 
or drive to adjust will automatically enable the corresponding color in the display. 
Delete the checkmark to see all colors, or to enable a different specific color through 
the Color Enable Control. 
CLAMP LOCATION – This option (formerly known as sync tip 
clamping) can brighten the image produced from certain high-
resolution high-frequency graphic sources. For...

5. It may be advantageous to go back and check the black band—adjust the 
blacklevel slidebar if necessary. NOTE: Readjusting blacklevels at this point 
affects the gain; only readjust when absolutely necessary. 
6.  Repeat Steps 3-5 with the other two remaining primary colors. When each 
primary color shows one optimized black band and white (or colored) band, 
the input levels for this source are correctly set. Upon exiting the Input Levels

Keep in mind that any Gamma Table choice sets the related Gamma value (shown in 
the Image Settings menu) to a 2.5 default, where it can be fine-tuned as desired. 
Different values (1-3) here indicate that the original gamma table has been adjusted 
with either the Gamma slidebar or direct key. 
SELECT COLOR ADJUSTMENT: In “Select Color Adjustment”, 
choose an overall color palette for all images. The “Max

With your sync cable, Z-screen and, if desired, emitter connected as described in the 
Using 3D in Mirage
 manual, select the option suited to your 3D configuration (see 
above). If Frame Delay is 2 (or 0), do not invert; if frame delay is 1 or 3, invert. 
Generally, an “Unlocked” setting is synchronized with the incoming L/R signal rather 
than the vertical sync output, and may be needed only with multi-projector 
installations in which the vertical...
