Installation
Choosing a location
Your projector is designed to be installed in one of two possible installation locations:
1. Floor in front of screen; or
2. Floor at rear of screen
Your room layout or personal preference will dictate which installation location you select.
Take into consideration the size and position of your screen, the location of a suitable power
outlet, as well as the location and distance between the projector and the rest of your
equipment.
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video format
each factors in the projected image size.
The maximum (native) resolution of the projector is 1024 x 768 pixels, which is a 4 to 3
aspect ratio (expressed as 4:3). To be able to project a complete 16:9 (widescreen) aspect
ratio image, the projector can resize and scale a widescreen image to the projector's native
aspect width. This will result in a proportionally smaller height equivalent to 75% of the
projector's native aspect height.
Thus, a 16:9 aspect image will not utilize 25% of the height of a 4:3 aspect image displayed
by this projector. This will be seen as darkened (unlit) bars along the top and bottom
(vertical 12.5% height respectively) of the 4:3 projection display area whenever displaying
a scaled 16:9 aspect image in the vertical centre of the 4:3 projection display area.
When determining the position of your projector, you should consider its intended use and
input signal aspect ratios. All inputs (other than composite Video being fed a 16:9 aspect
signal) will display in a 4:3 aspect ratio (and will require an additional 33% display height
than that of the scaled 16:9 aspect image projection area).
IMPORTANT: Do not select a permanent projector position based upon a 16:9 projection if you
will ever need to select an input other than composite Video being fed a 16:9 aspect signal.
I. Floor front: Select this location with the
projector placed near the floor in front of the
screen. This is the most common way to position
the projector for quick setup and portability.
II. Floor rear: Select this location with the
projector placed near the floor behind the screen.
Note that a special rear projection screen is
required. Set in the Advance > Mirror
menu after you turn the projector on.
