• 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 
narrow black bars on top and bottom. This is used for 
DVD players that output widescreen images compressed 
into 4:3 NTSC format. 
Size 
“Size” controls both the image width and height in tandem, maintaining the current 
aspect ratio (proportion) of the displayed signal data.

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.

PLUG & DISPLAY (EDID): By default, a Plug & Play 
(EDID) source outputs a signal according to the EDID 
information provided by the projector. To override this 
information and display in a different format (for 
example, if your Plug & Play [EDID] device does not 
support the projector’s resolution and/or frequency), 
select the desired Plug & Play (EDID) resolution from 
the list.

NOTE:  If the environment lighting changes, an adjustment of Gamma is 
recommended (see below). 
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...

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...

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 between this source and the AGC. 
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...

TINT: This slidebar adjusts the red/green color hue for true color reproduction of 
video and HDTV signals connected to Input 3 or 4. For best results, adjust tint while 
displaying an external test pattern—otherwise, it is recommended that tint remain at 
its default setting. 
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

AUTO INPUT LEVEL – Temporarily enter a checkmark only if you are an experienced 
user and you have an unusual source that you feel needs further color temperature 
and/or input level adjustment. This compensates for incoming out-of-range drives 
(white) and blacklevels (black) that would cause “crushing” of light and dark colors 
in the image. After entering a checkmark, wait for the six slidebar values to stabilize, 
then delete the checkmark and exit....
