Select
•
“DeFaUlT” for most sources (factory default). The image will be centered and
displayed as large as possible depending on the type of source.
Select
•
“nO ResIZInG” to display the image in its native resolution, which may or may
not match the projector’s 1400 x 1050 resolution. For example, for a source with a native
resolution of 800 x 600, “no resizing” will use the central 800 x 600 pixels and have a black
border—the black border areas are unused areas. See below.
Select
•
“FUll sIZe” to use all 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
•
“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”).
Select
•
“FUll HeIGHT
” to fill the display from top-to-bottom. Depending on the source, this
may create borders.•
Select
•
“aleTTeRbOX” to display a letterbox image in its native 16:9 aspect ratio. The
image will fill the screen from side-to-side and be centered.
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.
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 Pixel Phase
(next page).
