• Select
"FULL SCREEN"
pixels (1400 x 1050) 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 for display.
• Select
to fill the
"FULL WIDTH"
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 "letterboxed").
• Select
"FULL HEIGHT"
to fill the display from
top-to-bottom.
Depending on the
source, this may
create borders.
• Select
"ANAMORPHIC"
in its native 16:9 aspect ratio. The image will fill the
screen from side-to-side, and be centered between
narrow black bars on top and bottom. This is used for
DVD players that output widescreen images compressed
into 4:3 NTSC format.
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 (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.
