PRELIMINARY
• Full Size: Select Full Size to use all pixels for displaying the image, regardless of
source or original aspect ratio. Incoming source material having a different aspect ratio
than the projector will be stretched to fill the display.
• Full Width: Select Full Width to fill the projector’s display from left-to-right without
changing the original aspect ratio of the image. Depending on the source, data at the
top and bottom may be discarded (cropped), or the display may have black borders at
the top and bottom (called “letterbox”).
• Full Height: Select Full Height to fill the display from top-to-bottom. Depending on the
source, this may create borders.
•Anamorphic: Select Anamorphic to display an anamorphic image in its native 16:9
aspect ratio. The image will fill the screen from top-to-bottom and be centered between
narrow (64 pixels wide) black bars on each side.
• “Custom” Resizing: The “Custom” re-size descriptor automatically appears in the
Size and Position menu when any of the values for Size, Vertical Stretch, H-Position,
V-Position or Blanking do not correspond to those for a preset. This option is not
offered in the Resize Presets pull-down list.
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 tracking helps ensure that the image
quality is consistent across the screen, that aspect ratio is maintained, and that pixel
phase can be optimized (see 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.
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. 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 (described below).
Pixel Phase: 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. 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; that is, you may find that the image
appearance at “11” is identical to the image appearance at “38.” Use either setting in such
cases. If some shimmer from a video or HDTV source persists, use the “Filter” control in
the Image Settings menu (described later) to remove high-frequency noise from the signal.
H-Position: This option moves the image right or left within the area of available pixels.
V-Position: This option moves the image up or down within the area of available pixels.
Adjust “Pixel Tracking” before “Pixel Phase.”
