3.1 Aligning the Image
Aligning the image will probably not be necessary. However should there a be a slight misalignment, it
is important that you do this before you use the Position controls. Adjust the image so that it covers the
entire screen.
What is overscan?
Our rear projection technology is capable of show-
ing every pixel of the incoming image. Historically,
CRT televisions, especially cheaper sets could not
reliably show all the pixels without distortion.
Televion industry standards allow a television set to
chop off up to 20% of the image. This is known as
overscan. Some video content assumes that this over-
scanning is taking place and may not have picture
information all the way out to the edges. When
shown on our display, you may see black bars, lines of
white or other non picture information on the edges
of an image. Use the overscan setting to avoid seeing
this. Video inputs and YPbPr colorspace inputs have a
default overscan of 3% which will match most mod-
ern TV sets. Computer inputs default to 0% overscan
so you see the whole image.
What is effective resolution?
The Bengal is the thinnest rear projection DLP
product available. This thin technology comes with
some trade-offs. The ultra wide-angle lens that allows
it to be so thin causes the image to be distorted and
undisplayable at the edges. As a result, the native
1280x720 engine resolution is not viewable on the
screen. The effective resolution of the display (i.e. the
number of pixels visible on the screen) is about
1232x693 pixels, but may vary slightly from unit to
unit. Because the position of internal mirrors and
lenses may shift very slightly during shipment of your
Bengal, the effective resolution window may also
shift. The Image Alignment menu allows adjustment
of the effective resolution in order to compensate for
any minor variations that may occur after factory
alignment.
Aligning the Image
1. Turn on the AC power to the display. On first
turn on, the lamp will power up automatically.
(You may choose later to turn off the "auto lamp

Use the test pattern to align the image to the screen.
The
pattern is good for general alignment.
GRID
will allow you to see just how far
ILLUMINATE BORDER
from the edge of the screen the active image will be by
turning the background green. The green background
will appear outside the edges of the test pattern. It
will turn to black once you exit the menu.
