NOTE: By default, the projector samples at the correct frequency for most sources.
For best results, use a good test pattern such as a smooth gray consisting of a clear
pattern of black and white pixels, or a similar "half on, half off" graphic image, such
as the Windows shutdown screen. 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
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.
For best results, use a good test pattern such as a smooth gray consisting of a clear
pattern of black and white pixels, or a similar "half on, half off" graphic image, such
as the Windows 2000 shutdown screen. 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 "11" is identical
to the image appearance at "38", 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
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 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.
Advanced Size and Position
This submenu consists of the following options:
ACTIVE INPUT WINDOW:
only value indicates the current
size (i.e., area) 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. You can
also specify a specific active input
