• FILM MODE DETECT
Enables or disables film motion detection. Film mode detect is a control that you will not need to adjust. The 
image processor automatically detects the type of input for most types of interlaced signals. i.e. 3:2, 2:2. 
However, there are cases where progressive segmented frame signals (PsF, a broadcast Sony standard) are not 
detected properly. For those cases, the de-interlacer can be...

Section 3: Operation
Good RGB or input levels—that is, the drives and black levels for each of the three colors, red, green and 
blue—ensure that images from analog sources other than decoded video have maximum contrast without 
crushing black or white. By default (and in an “Auto Setup”), the projector automatically determines the best 
input levels by monitoring image content and adjusting the controls appropriately—further...

•CLAMP LOCATION 
Brightens the image produced from certain high-resolution high-frequency graphic sources. The projector 
automatically selects the best clamp location for most sources. Use the normal Back Porch location if the 
image is either sufficiently bright or overly bright. Select Sync Tip if the image appears unusually dim, if there 
are horizontal streaks across the image, or if there is...

•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 source 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 temperature of...

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 modified 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 SETTINGS - Submenu
• NOISE REDUCTION
Selects a filter sensitivity to noise. A higher value may improve noisy sources, but it will soften the image.
• BLOCK ARTIFACT REDUCTION 
Locates and reduces block edges produced by discrete cosine transform (DCT) based compression processing.
• MOSQUITO NOISE REDUCTION 
Reduces mosquito artifacts around sharp edges in DCT based compression by...

Optical Aperture
The optical aperture inside the projector controls the diameter of the light beam passing through the system. 
With a fully open aperture (slidebar default of 0), the maximum amount of light passes through for 
maximum brightness in your images. Increase the slidebar setting to reduce the aperture diameter and 
maximize contrast ratio instead. Performance of aperture depends on the lens in...

• MANUAL ZOOM/FOCUS
When this control is selected, the holding current is removed from the zoomand focus motors so that they can 
be changed manually.
 NOTE: Zoom and Focus should not be adjusted manually when this control is not 
selected, as this will result in damage to the motors.
•CALIBRATE 
The lens calibration procedure is needed each time a new lens is installed in order for the ILS feature to...

•TURN OFF IMAGE AFTER (min) 
This sets the activation interval (in minutes) for Auto Shutdown. If all activity (input signals, web or serial port 
activity, key presses) is lost for this length of time, and Auto Shutdown is enabled, an Auto Shutdown cycle 
will begin.
•ENTER STANDBY AFTER (min) 
This sets the interval (in minutes) between starting Auto Shutdown and entering Standby mode. Once Auto 
Shutdown...
