8.0 ADJUSTING THE IMAGE
50 R599790 - FORCE Series User Manual
Size
Controls both the image width and height in tandem, maintaining the current aspect ratio of the displayed signal
data.
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 tracking ensures that the image quality is consistent across the screen, the aspect ratio is maintained,
and that the pixel phase can be optimized (described below). Tracking determines the frequency of 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 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 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: One must 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 “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
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. If
disabled and the source is not a special case video source where a default stretch is defined, the source is scaled to
fit the platform.
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 1920 x 1080, the remaining active input window will be reduced to 1720 x 1080.
• Blanking (Top, Bottom, Left and Right)
Crop the image so that unwanted edges are removed from the display (changed to black). Blanking defines the size
of the Active Input Window, or area of interest. Range of adjustment depends on the source resolution and other
