Anamorphic Option
• Select
Anamorphic
to display an incoming Cinema scope signal in a 16:9 aspect ratio without the use of
an anamorphic lens mount. The image fills the screen from top-to-bottom, and be centered between
narrow black bars on each side.
Size Option
Select the Size option from the
Size and Position
menu. Size controls both the image width and height in
tandem, maintaining the current aspect ratio (proportion) of the displayed signal data.
Vertical Stretch Option
Select the Vertical Stretch option from the
Size and Position
menu. 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 Option
Select the Pixel Track option from the
Size and Position
menu. 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 (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 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
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 the Pixel Phase described next.
Pixel Phase Option
NOTE:
Adjust Pixel Phase after Pixel Tracking.
Select the Pixel Phase option from the
Size and Position
menu. 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.
