Brightness 
(
SHORT CUT: Press Bright and adjust the slidebar.) 
“Brightness” increases or decreases the amount of black in the image (0-100). For best 
results, keep close to 50. Start with a high value and decrease so that dark areas do not 
become black (i.e., are “crushed”). Conversely, high brightness changes black to dark 
gray, causing washed-out images.  
Gamma

SHORT CUT: Press Gamma and adjust the slidebar.)...

up noisy RGB images such as those from a PC. Adjust as desired, keeping in mind 
that reducing noise (which reduces high frequencies) may also soften the image. 
Color Space 
“Color Space” determines how the color components of an analog 
input signal are decoded for accurate color in the display. 
Selecting a color space option is useful only for analog signals 
connected to 
INPUT 1, INPUT 2, or INPUT 5. Although color space...

VIDEO STANDARD: For all but the more unusual video standards 
available in the world, the projector automatically detects the 
incoming horizontal and vertical frequencies and sets the projector’s 
processing of this signal to the corresponding standard. The current 
video standard name appears in the Video Options submenu, and 
includes an “A” if it has been auto-detected. Press 
 to view or 
select a different video...

DECODER LUMA DELAY – This control affects any incoming composite or S-video 
signal, delaying the luma signal (intensity) in relation to the chroma (color). In the 
image, increasing the luma delay will move luma (seen as a shadow where colors 
overlap) to the right slightly, with colors remaining in place. Decreasing this delay 
will move the shadow slightly to the left. If necessary for your current source, adjust 
so that no...

then delete the checkmark and exit. The Auto Input Level is automatically turned off 
upon exiting the Input Levels menu.  
BLACKLEVELS AND DRIVES – To check your image levels and adjust these controls: 
1.  Make sure overall “Contrast” and “Brightness” settings are both set to near 50. 
NOTE: Not required for “Auto” adjustment.

Contra st= 50 (approx.) 
• 
Bright= 50 (approx.) 
2.  Check the color temperature setup using...

from this source will then display correct blacks and whites without crushing.

Advanced Image Settings — SUBMENU 
Use the Advanced Image Settings 
submenu to make the adjustments 
necessary for lesser-used but more 
specialized applications on your 
projector. 
GAMMA TABLE: This control applies a 
default video or graphics gamma 
table or “curve” to your images, 
controlling the intensity of midlevel 
colors and producing maximum 
contrast, brightness and color 
performance. As shown at right, the...

of each color component in the Color Adjustment by X/Y or Color Saturation 
submenus. It is most often needed with multiple-projector applications. Select the 
color adjustment producing the best color accuracy for your application and 
installation. 
To configure a “User” color adjustment (gamut), use either the Color Adjustment by

Simulation 3D — SUBMENU OF ADVANCED IMAGE SETTINGS 
This submenu allows you to adjust 
the timing between the input signal 
and its appearance on screen. This is 
most useful in applications where you 
want to match the timing of the 
projector to other equipment, such as 
a video recording device in 
broadcasting environments.

value changes as it monitors the 
latency between input and output....

DETAIL THRESHOLD — Use “Detail Threshold” to define at what frequency level the 
“Detail” control will begin to magnify high frequencies, which adds details back into 
the image. Raise the threshold to ignore more of these high frequencies, and lower the 
threshold to magnify more of these frequencies. A setting of “0”, for example, means 
no noise will be ignored and all will be magnified. An ideal detail threshold is one in...
