• Full height fills the display from top-to-bottom. Depending on the source, this may create
borders.
• Anamorphic displays an anamorphic image in its native 16:9 aspect ratio. The image fills the
screen from side-to-side and be centered between black bars at top and bottom.
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. 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, 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 the Pixel Phase.
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.
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. Adjust Pixel Phase after Pixel Track.
If some shimmer from a video or HDTV source persists, use the Filter control to remove high-
frequency noise from the signal.
