•Scan-quadrupled sync-on-green.
For these signals, change the color Space to RGB, and then define a new channel for future use.
VIDEO OPTIONS 
This submenu is used with video sources only.
•AUTOMATIC GAIN CONTROL (AGC): 
AGC affects decoded video images only. Enter a 
checkmark (default) in most instances. Activate 
the decoder’s AGC circuit to ensure properly 
bright images. Delete the checkmark if a decoded 
video image exhibits strange color...

•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:

•CHROMA/LUMA DELAY: 
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 shadows occur 
with adjacent colors.

compensating for differences in sources and cabling, to perfect the source image input levels and 
eliminate the “overshoot” and “undershoot”. NOTES: 1) Input Levels are of limited use with digital 
signals, but do offer some ability to tweak poorly mastered source materials. 2) Input levels apply for 
the current source only, but for any color temperature used. 3) Assuming that color temperature has 
been set up based on the...

•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 significant color drift. This moves the clamping...

•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...

video signals. A simple gamma curve is a true power curve that does not alter the contrast or the 
intensity of mid-level colors. Although the projector automatically applies either the graphics or video 
curve according to what type of incoming signal is detected, in some cases you may wish to override 
this default and use graphics gamma for a video source or video gamma for a graphics source. 
Alternatively, if neither default is ideal, you may...

DETAIL SETTINGS:
• DETAIL:
Adjusts the sharpness of the image. Setting detail 
above the halfway point can introduce ‘noise’ in 
the image. Lower settings can improve a noisy 
signal.
• TEXTURE ENHANCEMENT:
Applies texture detail enhancement based on 
adaptive horizontal, vertical, and diagonal large edge and small edge enhancement processes.
•DETAIL THRESHOLD: 
Selects a filter sensitivity to noise. A higher value may improve noisy...

SELECT COLOR ADJUSTMENT
Select the output color adjustment most suited to this input signal. The options include the following:
Max Drives - All color 
adjustments are turned off 
allowing the projector to 
run at maximum brightness. 
Color Temperature - 
Allows you to specify a 
color temperature between 
3200 and 9300 based on the 
setting of the color 
temperature slidebar.
Expressed in degrees Kelvin [3200K, 5400K, etc.]. Lower numbers appear...

set the Manual Iris control to set the iris to a fixed position, as a percentage of fully open. If Dynamic 
Iris Mode is set to OFF, the position of the iris will be fixed at fully open.
• MANUAL IRIS:
When the Dynamic Iris is set to manual, adjust the aperture for a fixed position where 100% 
represents fully open. Adjusting the aperture will increase or decrease the levels of blacks in dark 
scenes.
