the pixel-sampling clock, indicated by the number of incoming pixels per line, so that all pixels generated by a 
particular source are sampled. 
NOTE:  By default, the projector samples at  the correct frequency for most sources.  
For best results, use a test pattern such as a smooth  grey consisting of a clear pattern of black and white 
pixels. Adjust the slide bar until the vertical stripes  broaden to the...

BLANKING (TOP, BOTTOM, LEFT, and RIGHT) 
Crop the image so that unwan ted edges are removed from the 
display (changed to black). Blanking defines the size of the 
Active Input Window,  or area of interest. Range of adjustment 
depends on the source resolution and other factors. 
NOTE:  Blanking a PIP image resembles zoom. For 
example, left Blanking zooms the right side of the PIP 
image; Right Blanking zooms...

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 b ecome black. Conversely, high brightness changes black to 
dark grey, causing washed-out images. 
COLOR SPACE
Determines how the color components of  an analog input signal are decoded for accurate color in the display. 
Useful only for...

• VIDEO STANDARD 
The projector automatically detects the incoming horizontal and vertical frequencies and sets the processing of 
this signal to the corresponding standard. Th e current video standard name appears in the  Video Options 
submenu, and includes an “A” if it is auto-detected. Press  E
NTER to view or select a different video standard 
from those available to the projector— any that are disabled...

•SAMPLING MODE  
Sets the color sampling mode for a digital signal to either YCbCr 4:4:4, RGB or YCbCr 4:2:2. The proper 
sampling mode is determined automatically by the projector; you can override this setting.
• FILM MODE DETECT
Enables or disables film motion detectio n. Film mode detect is a control that you will not need to adjust. The 
image processor automatically detects th e type of input for most...

INPUT LEVELS - Submenu
NOTES: 1) Because the projector 
automatically optimizes in put levels for all but 
the most unusual of sources, it is 
recommended that only experienced users use 
the Input Levels submenu.  
2) Before 
beginning, check that  overall contrast and 
brightness settings are near 50 and that color 
temperature is properly set up on an internal 
greyscale test pattern.  
3) Refer to  3.1.1...

4. If black levels are too high (and/or whites are too low, which is rare), you likely have a noisy source that is 
producing skewed input levels. Enable “Auto” in the  Input Levels menu. Wait for all six values to 
stabilize. Alternatively,  do not use “Auto”—reduce black levels  manually instead. Judge by eye and 
change one or more of the six levels as necessary to  obtain proper blacks and whites. You may...

•COLOR ENABLE  
Select which color or colors you want  to see in the display, useful while working with color temperature white 
levels or input levels. 
NOTES: 1)  Input levels apply for the current sour ce only, but for any color temperature 
used.  
2) If color temperature is set up based on the internal  test patterns, you can set up input levels for a given 
source so that it matches the color temp erature...

The 2.22 curve is a power curve typically used to encode graphics 
and video sources, see  Figure 3-29 Gamma Curve . The standard 
curve (auto setup default) is a mo dified 2.22 curve with a small 
linear section in the black that enhances the detail in darker areas 
of the projected content. Typically standard or 2.22 is used for all 
sources. Alternatively, if neither default is ideal, apply a simple 
gamma...

• NOISE REDUCTION
Selects a filter sensitivity to noise. A higher value may improve noisy sources, but it will soften the image.

Reduces mosquito artifacts around sharp edges in DCT ba sed compression by dynamically...
