the pixel-sampling clock, indicated by the number of incoming pixels per line, so that all pixels generated by a
particular source are sampled.
NOTE: By default, the projector samples at the correct frequency for most sources.
For best results, use a test pattern such as a smooth grey consisting of a clear pattern of black and white
pixels. Adjust the slide bar until the vertical stripes broaden to the point where one large stripe fills the
image. If the image still exhibits some shimmer or noise, adjust Pixel Phase (below).
PIXEL PHASE (analog input signals only)
NOTE: Adjust "Pixel Phase" after "Pixel Tracking".
Adjust pixel phase when the image (usually from an RGB source) still shows shimmer or "noise" after pixel
tracking is optimized. Pixel phase adjusts the phase of the pixel-sampling clock relative to the incoming signal.
Adjust the slide bar until the image stabilizes and each pixel is clearly defined. You may notice that you can
stabilize the image at more than one point—i.e., you may find that the image appearance at "5" is identical to
the image appearance at "25", thus you can use either setting.
If some shimmer from a video or HDTV source persists, use the "Filter" control to remove high-frequency
noise from the signal.
H-POSITION
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
Moves the image up or down 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 vertically. This varies widely according to the signal—watch the image while
adjusting.
KEEP ASPECT ON AUTO SETUP
Ensures that auto setup for any source will maintain the input aspect ratio when the default size is calculated.
NTSC and PAL formats always keep aspect ratio during auto setup regardless of the Keep Aspect on Auto
Setup control.
BLANKING - Submenu
This submenu consists of the following options:
• ACTIVE INPUT WINDOW
This read-only value indicates the current size of your displayed data or "region of interest" as defined by the
blanking controls. By default, the projector automatically determines what portion of its full resolution to use,
and pixels in the surrounding borders are turned off. To specify a specific active input window size by adjust
one or more "Blank" settings. For example, if you have blanked (cropped) 100 pixels from both the left and
right edges of an incoming source of 1400 x 1050, the remaining active input window will be reduced to 1200
x 1050.
