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. 
Use “Vertical Stretch” to change the aspect ratio of the display.  
Pixel Track 
Steady flickering or several soft vertical stripes or bands across the entire image 
indicates poor pixel tracking. Proper pixel...

relation to the total number of pixels available vertically. This varies widely 
according to the signal—watch the image while adjusting.

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.

Brightness 
(
SHORT CUT: Press Bright and adjust the slide bar.) 
“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 images....

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 “Filter”...

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 between this source and the AGC. 
VIDEO STANDARD: For all but the more unusual video 
standards...

COLOR: This slide bar 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 slide bar 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...

internal test patterns, you can then set up input levels for a given source so that it 
matches the color temperature of the internal test patterns.
