OPERATION
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 slidebar 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 slidebar 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
— SUBMENU
This submenu consists of the
following options:
This
ACTIVE INPUT WINDOW:
read-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 window size by adjusting 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
