• AUTO SOURCE: If checked, (default), the projector can automatically locate 
this channel when an incoming input signal matches. If not checked, the 
projector can locate the selected channel only when it is directly selected via 
C han nel on the keypad—and a change in input signal will not result in a channel 
change. 
• 
LOCKED: If checked, all of the image settings for this channel are disabled. If 
unchecked (default), all available image...

In the Size and Position menu, 
you can increase or decrease 
the size of your image, change 
its proportion (aspect ratio), 
move the image to a specific 
area of the screen, and refine 
other related parameters. Use 
Size and Position controls to 
match the image precisely to 
the screen used at the site. 
Refer to Using Slidebars and 
Other Controls (earlier in this section) if you need help using any of the options and 
controls. Changes made in the...

• Select
 “NO RESIZING” to display the image in its native resolution, which may or 
may not match the projector’s 1400 x 1050 resolution. For example, for a source 
with a native resolution of 800 x 600, “No Resizing” will use the central 800 x 600 
pixels and have a black border—the black border areas are unused areas. See 
below. 
 
• Select “FULL SIZE” to use 
all pixels (1400 x 1050) for 
displaying the image, 
regardless of source or 
original...

• Select “ANAMORPHIC” to display an anamorphic image 
in its native 16:9 aspect ratio. The image will fill the 
screen from side-to-side and be centered between black 
bars at top and bottom.  
 
Size 
“Size” controls both the image width and height in tandem, maintaining the current 
aspect ratio (proportion) of the displayed signal data.  
Vertical Stretch 
“Vertical Stretch” adjusts the height of the image while keeping the width constant.

H-Position 
This option moves the image right or left within the area of available pixels. 
NOTE: The value shown represents where the approximate center of the image lies in 
relation to the total number of pixels available horizontally. This varies widely 
according to the signal—watch the image while adjusting. 
V-Position 
This option moves the image up or down within the area of available pixels. 
NOTE: The value shown represents where the...

BLANKING (TOP, BOTTOM, LEFT, and 
RIGHT): 
Crop the image as desired so 
that unwanted edges are removed from 
the display (changed to black—see 
right). Blanking defines the size of the 
Active Input Window, or area of 
interest. Range of adjustment depends 
on the source resolution and other 
factors.  
 
 
 
PLUG & DISPLAY (EDID): By default, a Plug & Play (EDID) 
source outputs a signal according to the EDID information 
provided by the projector....

Contrast 
(
SHORT CUT: Press Contra st and adjust the slidebar.) 
“Contrast” increases or decreases the perceived difference between light and dark 
areas of your image (0-100). For best results, keep close to 50. If contrast is set too 
high, the light parts of the image lose detail and clarity. If set too low, the light areas 
will not be as bright as they could be and the overall image will be dim. For best 
results, start with a low value and...

Detail 
“Detail” adjusts the sharpness of a video image so that edges remain clearly defined. It 
can be particularly useful if a significant “Noise Reduction” adjustment has caused the 
image to appear too soft. Adjust until the display is as sharp as desired, keeping in 
mind that because “Detail” adds some high frequencies back into the image, it can 
also re-introduce a certain degree of noise. 
Noise Reduction 
“Noise Reduction” is similar to the...

Video Options — SUBMENU 
This submenu is used with video 
sources only (
INPUTS 3 or 4). 
ENABLE DECODER AGC:  Automatic 
Gain Control (AGC) affects decoded 
video images only. Enter a checkmark 
(default) in most instances—this 
activates the decoder’s AGC circuit to 
ensure properly bright images. Delete 
the checkmark if a decoded video image exhibits strange color artifacts such as stripes 
in highly saturated colors, indicating an incompatibility...

COLOR — This slidebar adjusts the color saturation level, i.e. the amount of color in a 
video image. Lower settings produce less saturated colors — for example a setting of 
“0” produces a black and white image. If the color level is too high, colors will be 
overpowering and unrealistic. 
TINT — This slidebar adjusts the red/green color hue for true color reproduction of 
video signals connected to 
INPUT 3 or 4. For best results, adjust tint while...
